Geothermal Resources in the Balkans 1

The Database of Geothermal Resources in the Balkans

contains information on 237 specific geothermal sites or

projects in the six countries which constitute the Balkans –

Albania, Bosnia and Herzegovina, Croatia, the Former

Yugoslav Republic of Macedonia (FYR Macedonia),

Slovenia, and Yugoslavia (Serbia and Montenegro). 

A summary of geothermal resources found in the six

countries is shown in Table 1. The 237 sites have a

projected electricity generation potential of 439 MWe and

a direct use potential of 3,390 MWt. Thirty-three or 14%

of the sites have a temperature of 100oC or more, and may

be suitable for power generation development. 

The Database and market research report were designed,

built, and written by a team led by Liz Battocletti of Bob

Lawrence & Associates, Inc. (BL&A) for UT-Battelle

LLC under Purchase Order Number F99-181039,

“Collection and Assembly of Published Data on

Geothermal Potential.” It was compiled using information

collected in an extensive data and Internet search which

accessed technical literature dating back 25 years, as well

as numerous U.S. and Balkan sources.

Dynamic Database

The Database is designed to be dynamic. Created using

Microsoft® Access 2000, it can be easily updated or

modified to include specific data which the industry would

find most useful. In addition, the Database can be made

more comprehensive by adding pertinent data, e.g., local

population and market data, location of transmission lines

and roads, etc., using the Geographic Information System

(GIS), to the present structure. 

To date, BL&A has conducted similar extensive surveys

of geothermal resources in Latin America and the

Caribbean, Turkey, Poland, China, Hungary, and Russia,

building databases for each. The databases could be

adapted for posting on the World Wide Web and searched

using a variety of variables, e.g., country, temperature of

resource, estimated power potential, and other parameters.

Slightly smaller than Maryland, Albania shares land

borders with Greece, the Former Yugoslav Republic of

Macedonia, the Federal Republic of Yugoslavia’s southern

province of Kosovo, and the Republic of Montenegro –

and an off-shore border with Italy. 

The poorest country of Europe has faced many challenges

following the collapse of communism and the centrally

planned economy. In 1991 and 1992, economic

depression and lack of opportunity led to the mass exodus

of thousands of young Albanians to Italy and Greece. 

The economy recovered in 1993-95 but in election year

1996, the government’s weakening resolve to maintain

stabilization policies increased inflation and the budget

deficit. 

The collapse of financial pyramid schemes in early 1997 –

which had attracted deposits from a substantial portion of

Albania’s population – triggered an economic meltdown

and widespread civil insurrection including more than

1,500 deaths, widespread destruction of property, and an

8% drop in GDP. Following fundamental reforms in

1998, the economy recovered. 

In early 1999, the Government of Albania (GOA), with

international assistance, handled the influx of nearly

500,000 Kosovar refugees (which increased the country’s

population by 14%) with minimal disruption to the

country. 
Geothermal Resources in the Balkans 6

Currently, Albania is reviving its infrastructure and

privatizing potentially lucrative telecommunications,

energy, banking, and mining companies. The country has

a well-educated and inexpensive work force, an

entrepreneurial populace, and is near lucrative Western

European markets. U.S. products and companies are

highly regarded by Albanian consumers; the GOA is eager

to attract U.S. investment. 

Albania’s economy is currently growing by 7-8% a year. 

Power Summary

Albania has a total installed capacity of 1,892 MWe –

1,668 MWe from hydropower plants (HPPs) and 224

MWe from thermal power plants (TPPs). In 1998,

Albania consumed 5.29 billion kWh, produced 5.15 billion

kWh, and imported 500 million kWh of electricity. With

over 90% of production supplied by HPPs, the country is

vulnerable to frequent droughts. Much of the equipment is

old and in need of renovation. Technical and nontechnical losses are high. 

Only 35% of the country’s hydropower potential has been

developed. The Albanian, state-owned electricity

monopoly, Albanian Power Corporation (Korporate

Elektoenergjetike Shqiptare [KESH]), plans to build two

new HPPs by 2006, and three steam-power plants.2 A grid

overhaul and the rehabilitation of four old HPPs are

underway. 

In addition to hydropower, Albania has significant

hydrocarbon resources (oil and gas) as well as vast

reserves of coal. Renewable energy, e.g., solar, wind, and

low-enthalpy geothermal for heating, are also potential

sources of energy.

Demand for electricity has been increasing 6% annually

since 1992. Albania became a net energy importer in

1998, primarily due to an increase in consumer demand

for electricity as households imported appliances and

electric heaters. Nationally, 80% of home heating demand

is covered by electricity. The country imports 37% of its

electricity. Forecasters estimate that electricity demand

could reach 9.01 TWh in 2010 (up from 4.57 TWh in

1995). 

With its significant petroleum and natural-gas reserves,

coal deposits, and hydropower resources, Albania could

produce enough energy for domestic consumption and

export fuels and electricity. 

2 China International Water and Electric Corporation

(CWE) will build a 168 MWe (2x84) hydropower

plant in Bushat. Both turbines should be operational

in 2004.

Government / Legislation

The Government of Albania is very interested in

increasing the share of foreign investors’ participation in

the energy sector of Albania.

Albania has no umbrella energy policy law or basic

principles for the whole energy sector in the long-term

perspective. The country also lacks legislation in the field

of renewable energy sources, as well as energy

conservation. The GOA, however, is in the process of

preparing an Energy Law and an Energy Efficiency Law.

The principal laws relating to investment in the energy

sector are the following: 

• Law on Competition, No. 8044 of December 1995 

• Law on Environmental Protection, No.. 7664 of

January 1993

• Mining Law No.7796 of February 1994

• Law on Foreign Investment, No. 7764 of

November 1993

• Law on Concessions and the Participation of the

Private Sector in Public Services and

Infrastructure, No. 7973 of July 1995

• Law on Electricity, No. 7962 of July 1995

• Law on the Purchase and Sale of Urban Land, No.

7980 of July 1995

• Law on the Privatization of the Power Sector, No.

7963 of July 1995 

• Law on Electricity Regulation, No. 7970 of July

1995

The Albanian energy sector is not a legal monopoly;

foreign investment is allowed and is not subject to

government authorization. The only limitation to foreign

investment is the issue of land ownership rights. Foreign

investors may own real estate in Albania with the

exception of agricultural land, forests, pastures, and

meadows. The latter may be leased, however, for up to 99

years under the provisions of the Albanian Civil Code. 

Foreigners may buy urban land if they invest three times

the purchase price. 

A bilateral investment treaty between the United States

and Albania was signed in 1995 and entered into force on

3 January 1998. This treaty ensures U.S. investors receive

national or most-favored-nation treatment and provides for

dispute settlement.

Albania’s energy sector remains under state ownership. 

The International Monetary Fund (IMF) has urged Albania

to complete reforms in the energy sector in order to

continue the country’s economic progress, specifically

advising the GOA to improve payment collection, promote

alternative sources of energy, and change the tariff

structure. 

Albania’s power system development strategy has been

elaborated on the basis of studies carried out by

international consultants and financed by the World Bank
Geothermal Resources in the Balkans 8

and the European Bank for Reconstruction and

Development (EBRD). The strategy foresees:

• Meeting the domestic electricity demand at

the lowest cost and good quality by

minimizing the interruption of supply to the

customers; 

• Exporting excess electricity production;

• Rehabilitating existing HPPs and TPPs;

• Developing new capacities for HPPs as well

as for TPPs burning imported natural gas;

• Decreasing technical and non-technical

losses within the system;

• Restructuring the power system; and

• Attracting private foreign and local capital.

Ministry of Public Economy and Privatization

Since 1997, the Ministry of Public Economy and

Privatization represents the Government as the owner of

the energy sector assets. (Formerly called the Ministry of

Mineral Resources and Energy.)

National Energy Agency

The National Energy Agency is responsible for energy,

and acts as an adviser to the Minister of Public Economy

and Privatization.

Entity for Electricity Regulation (EER)

Following the adoption of Law No. 7970 on Electricity

regulation in July 1995, an independent Entity on

Electricity Regulation (EER) was established in

September 1995. The EER is responsible for tariff

regulation and licensing in the power sector, and is

accountable to the Council of Ministers.

Energy prices, with the exception of electricity prices,

have been liberalized. In April 1994, electricity prices

were increased sharply, to bring them closer to production

costs. It is estimated that the long run cost of supply is 

4.2-4.6¢/kWh.3

Albanian Power Corporation (Korporate Elektoenergjetike

Shqiptare [KESH])

KESH is a state-owned joint stock company, established

in 1992 in accordance with the Law of State Entities, and

operated under the jurisdiction of the Ministry of Public

Economy and Privatization.

KESH is responsible for power generation and

transmission. It also distributes power through 38

subsidiaries, including Shkoder, Elbasan, and Vlora,

which were subject to an unsuccessful pilot privatization

process.

1 LEK = 0.007067 USD (12 February 2001)
Geothermal Resources in the Balkans 9

In July 1995 the Albanian parliament passed a package of

laws to enable major changes in the management of the

power sub-sector. The laws provide for the establishment

of a regulatory system, the staged privatization of KESH’s

distribution functions, and the development of

independent private power production. 

KESH will be privatized by 2003-2005 most likely by

international tenders. 

No Specific Law for Geothermal

Albania has no specific geothermal legislation. No

guidelines exist for geothermal exploration permits or

licensing geothermal exploitation. Geothermal licensing

is issued by the state. 

The GOA supports investment in geothermal projects

through price indexing (price in relation to other energy

sources) and the free utilization of existing wells.

Geothermal Sites / Projects

Albania is a predominantly mountainous country. 

Approximately 75% of its territory is highlands with

elevations of 300 m. One mountain range, which

generally runs from north to south, is the southern end of

the Dinaric Alps. The North Albanian Alps, a glaciated

limestone range in extreme northern Albania, are

extremely rugged. 

The greatest heat flow densities in Albania are located in

the center of the Preadriatic Depression, where the value is

42 mW@m

-2 , and in the east of the ophiolitic belt, where

heat flow density reaches values of up to 60 mW@m

-2.

 

Temperatures vary from a minimum of 12oC at a depth of

100 m to a maximum of 105.8oC at a depth of 6000 m. In

the central part of the Preadriatic Depression, there are

many deep oil wells where the temperature reaches up to

68oC at a depth of 3000 m. The isotherm runs in a

direction that fits that of the strike of the Albanides. The

configuration of the isotherm is the same down to a depth

of 6000 m. With increasing depth, the zones of highest

temperature align in a direction southeast to northwest,

towards the center of the Preadriatic Depression and even

further towards the northwestern coast (Frasheri, 2000).

Albania has many low enthalpy thermal water springs and

wells with temperatures up to 65.5oC. The country has

three main geothermal areas: Kruje, Ardenica, and

Peshkopi. The geothermal potential of these three areas is

39-63 GJ/m2 (Frasheri, 1999). 

The Kruje geothermal area is the largest geothermal area

in Albania. It begins on the Adriatic coast, north of

Rodoni Cape in the Ishmi region, continues southeast to

Tirana down to the Albanian-Greek border, and extends

into the Konica district in Greece. Aquifer temperatures

have been calculated to be 145-250oC. Surface water

temperatures vary from 30oC to 65.5oC with flow rates of

3.5-15 l/s (Frasheri, 1999). 
Geothermal Resources in the Balkans 10

Located on the coastal areas, the Ardenica geothermal area

is comprised of the molassic-neogenic braehyanticline

Ardenica structure, the Semani anticline, the northern

pericline of the Patos-Verbas carbonatic structure, and the

neogenic molasses [sic] which cover it in the Verbas

sector. The Ardenica geothermal area extends on that part

of the peri-Adriatic Depression where the

Vlora-Elbasan-Diber transverse passes. Water

temperatures from deep wells in this area are 32-38oC;

flow rates are 15-18 l/s (KAPA Systems and EGEC,

1999). 

The Peshkopi geothermal area is situated in northeast

Albania in the Korabi hydrogeologic zone. Two

kilometers east of the town of Peshkopi, thermal springs

flow out on the Banja river slope, which is composed of

flysch deposits. These springs are linked with the

disjunctive tectonic zone, in the Ohri-Diber deep fault,

peripherically of the Permian-Triassic gypsum diapir, that

has penetrated the Eocene flysch which surrounds it in a

ring-like pattern. Water temperature is 43.5oC; flow rates

are 14-17 l/s (Frasheri, 1999). 

In addition to Kruje, Ardenica, and Peshkopi, numerous

thermal springs are found across Albania. Situated

primarily in tectonic fractures, thermal springs have

temperatures of 21oC to 58oC.

Geothermal studies have been conducted throughout

Albania. Temperature maps have been compiled for

different levels of up to 500 m depth. Geothermal

gradient maps and heat flow density maps have also been

drawn. Greater activity is needed in an assessment of

Albania’s geothermal resources, definition of development

goals, and selection of priority areas. 

Hot springs have been used mostly for bathing and

vacation spas; little actual development has occurred.

Albania has no electricity generated from geothermal

resources. The country’s potential markets for geothermal

are district heating, greenhouses and agriculture, and

cascaded uses, and to a lesser extent – health spas,

swimming pools, and industrial processes. Financing is

available for geothermal projects as loans with

commercial interest rates. 

The Database of Geothermal Resources in the Balkans

contains information on 22 specific geothermal sites or

projects in Albania. See Table 2 for a complete listing of

the sites, their development status, temperature (oC), and

electric power generation potential. A complete

description of each site, to the extent information is

available, is included in the Appendix.

Albania’s highest enthalpy geothermal resource identified

to date is Peshkopi where the temperature is 105.8oC at

6000 m. The average temperature of all sites in Albania is

40.6oC. One site has a temperature of 100oC or more.

Slightly smaller than West Virginia, Bosnia and

Herzegovina (BiH) is divided into two highly autonomous

entities: the Federation of Bosnia and Herzegovina

(Federation), composed primarily of Bosnian Muslims

(Bosniaks) and Croats, and the Republika Srpska (RS),

composed primarily of Bosnian Serbs. BiH is bordered by

Croatia, Serbia, and Montenegro. 

Both parts of the country have considerable autonomy. 

The same governing and civil institutions are generally 

duplicated in each. The central governing entity in

Sarajevo is weak and can act only with consensus of the

Federation and RS. 

Once the scenic backdrop to the 1984 Winter Olympics4,

Sarajevo and Bosnia and Herzegovina were devastated by

the 1992-1995 Bosnian War.5

 An estimated 250,000

people were killed, more than 200,000 wounded, and

13,000 permanently disabled. Some 1.2 million people

were refugees and an additional 850,000 were internally

4 Sarajevo is considering a bid to secure the Winter

Olympics in 2010.

5 Bosnia and Herzegovina’s declaration of

sovereignty in October 1991 was followed by a

referendum for independence from the former

Yugoslavia in February of 1992. The Bosnian Serbs

– supported by neighboring Serbia – responded with

armed resistance aimed at partitioning the republic

along ethnic lines and joining Serb-held areas to

form a “greater Serbia.” 
Geothermal Resources in the Balkans 13

displaced. Over 400,000 land mines located along the

front lines continue to pose a hazard. 

Signed in November 1995, the Dayton Agreement brought

an end to the conflict, and divided the country into two

parts. In 1995-96, a NATO-led international

peacekeeping force (IFOR) of 60,000 troops served in

Bosnia to implement and monitor the military aspects of

the agreement. IFOR was succeeded by a smaller,

NATO-led Stabilization Force (SFOR) whose mission is

to deter renewed hostilities. SFOR was restructured in

early 2000 and currently numbers about 20,000 troops.

Immediately following the war, output plunged to 25% of

the pre-war 1990 level. Unemployment was 80-90% with

most households surviving off humanitarian assistance. 

The international community endorsed a US$5.1 Billion

Priority Reconstruction Program. BiH’s political and

economic situation is improving slowly. Elected in

November 2000, Bosnia’s new reform-oriented

government, the first elected since the war, has pledged to

focus on economic reform, building a functioning state,

returning refugees, and tackling corruption. 

According to the IMF, Bosnia’s economy growth rate in

2000 was a healthy 10% and inflation under control at

2-3%.

Power Summary

The Bosnian War had a major impact on BiH’s energy

sector. Overall, damages were estimated at US$1.34

billion. Seventy percent of BiH’s generating capacity and

60% of its transmission network and control systems were

damaged and made inoperable. District heating facilities

in many towns were also severely damaged. Following a

massive influx of foreign assistance, by 1998, generation

had recovered to 78% of its pre-war levels. 

In addition, prior to the war, BiH had a countrywide,

vertically-integrated state-owned power company. After

the war, three Entity-owned utility companies were

created: two in the Federation – Elektroprivreda BiH

(EPBiH) and Elektroprivreda Mostar (EPM), and one in

the RS – Elektroprivreda Repbublika Srpska (EPRS). 

Despite being interconnected, the three companies are

virtual monopolies within their territories. 

As a whole, BiH has a total installed capacity of 3,999

MWe – 51% in hydroelectric plants and 49% in thermal

power plants powered by coal or lignite. Sixty-five

percent of the capacity is located in the Federation. The

power plants’ average age is 22 years. The country has no

identified oil or natural gas reserves. Coal reserves are

estimated at 3.8 billion tons; more than 60% is lignite. 

The country’s rivers – the Bosna, Drina, Una, Vrbas,

Nerevta, and Sava – are an abundant source of

hydropower. 
Geothermal Resources in the Balkans 14

BiH has several proposed greenfield power projects. 

EPBiH plans to award a BOT (Build-Operate-Transfer)

contract for the 118 MWe Konkjic HPP. EPRS plans to

build the 450 MWe Buk Bijela HPP. And EPM has plans

for a 550 MWe Kongora TPP and two HPPs totaling 100

MWe at Mostarko Blato and Tihaljina. Enron is

negotiating with EPM. 

In addition to large HPPs, BiH has little renewable

resources developed. BiH issued an invitation for bids to

build 20 small hydropower plants on a BOT basis. There

is also an interest in developing windmills.

Energy consumption has not grown as quickly as

expected. Following growth of 10% in 1998, gross

consumption increased only 2.5% in 1999. Distribution

gross consumption grew 2.8%; direct consumption

decreased 3.4%. The modest increase in 1999 resulted

from a warmer winter and reductions in distribution

losses. 

The World Bank Second Electric Power Reconstruction

Project was designed to restore normal and reliable power

supply in Bosnia and Herzegovina by increasing coal

production, upgrading generation capacities, and

rebuilding transmission and distribution networks. The

US$200-million Third Power Reconstruction Project

(“Power 3"), currently under preparation, will continue

post-war reconstruction with support for restructuring and

reforming the power sector. A major objective is to

reconnect BiH to the Union for the Coordination of

Transmission in Europe (UCTE), especially important as

BiH is a net energy exporter. BiH exports electricity to

Croatia, Montenegro, Italy, and Slovenia. 

Government / Legislation

The BiH state-level government is headed by a threemember Joint Presidency. The Presidency appoints the

state-level Council of Ministers. Simultaneously, each

Entity has a presidency and council of ministers. Except

for the Joint Power Coordination Center (JPCC), there are

no state-level energy institutions. 

Elektroprivreda BiH (EPBiH) 

EPBiH, headquartered in Sarajevo, was created in 1993. It

is the largest electricity provider in BiH serving 597,000

customers. Supervision of the Federation’s electric sector

rests with the Ministry of Energy, Mining, and Industry.

Tariffs are proposed by the company’s management board

and approved by the Federation’s Council of Ministers.

There is no independent, apolitical regulation at this time,

and there is no regulatory coordination with the other two

utilities, EPM and EPRS.

Elektroprivreda Mostar (EPM)

EPM is headquartered in the city of Mostar and serves the

western part of the Federation. EPM is not monitored by a

regulatory agency. During the war, the regional

government set retail prices; currently, the utility suggests
Geothermal Resources in the Balkans 15

prices to the local administrations. It is then up to the

cantons and municipalities to decide how to collect that

revenue from their electric customers. If the municipalities

feel that the rate is too high to be passed through, they

have to make up the difference.

Elektroprivreda Republika Srpska (EPRS)

The Assembly of Republika Srpska established EPRS in

June 1992 as a public enterprise according to the Law on

the Electrical Power Industry. EPRS’s operations are

overseen by its government-appointed management board

of directors. There is no independent regulatory agency. 

Electric prices are recommended by the utility to the 

government. These recommendations are based on the

utility’s cost of production, transmission, and distribution.

The government then decides on the consumer prices. 

The Ministry of Mining and Energy controls EPRS and

sets prices. 

Joint Power Coordination Center (JPCC)

In 1999, EPBiH, EPM, and EPRS established the JPCC to

coordinate the work of the three power transmission

systems in a secure and effective manner and to ensure the

transmission of electric energy from generating facilities

to domestic and foreign consumers. The ultimate goal is to

establish full operation of the 400 kV grid and its

synchronization with the Western European Pool and EU

systems.

At the State and Entity levels, BiH has virtually no legal

and regulatory framework for the power sector. The

World Bank has taken the lead in the reconstruction,

restructuring, and privatization of the power sector. 

Norwegian experts, with assistance from the Entity

Ministries, are preparing State and Entity electricity acts. 

The goal is to establish a system which meets EU

standards. Unbundling is envisioned as the preferred way

of restructuring and privatization of generation capacities

is to follow. This scheme would allow independent power

producers (IPPs) to enter the market on a larger scale. The

Law on the Policy of Foreign Direct Investments is very

liberal but not sufficient to attract large IPPs.

No Specific Law for Geothermal

Bosnia and Herzegovina has no specific geothermal

legislation at the State or Entity levels. In the Federation,

geothermal resources are covered by the Water Act and

the Decree on Concession for Water Resources. The

Federation Ministry of Agriculture, Water Resources, and

Forestry is responsible for geothermal resources. The

situation is similar in the RS. No guidelines exist for

geothermal exploration permits or licensing geothermal

exploitation. 

Geothermal Sites / Projects

Most of Bosnia and Herzegovina is covered by the Dinaric

Alps. Little exploration for geothermal resources has been

done. The country’s geothermal potential for space
Geothermal Resources in the Balkans 16

heating and balneological purposes, based on existing

wells, is about 33 MWt (KAPA Systems and EGEC,

1999).

A 1-MWe geothermal power pilot plant was to be built in

Sarajevo prior to the civil war. Due to lack of financing,

however, the project has been put on hold. The resource

has a temperature of 58°C and a flow rate of 240 l/s.

The Database of Geothermal Resources in the Balkans

contains information on 3 specific geothermal sites or

projects in Bosnia and Herzegovina. See Table 3 for a

complete listing of the sites, their development status,

temperature (oC), and electric power generation potential. 

A complete description of each site, to the extent

information is available, is included in the Appendix.

BiH’s highest enthalpy geothermal resource identified to

date is Bosanki Samac with a temperature of 85oC. The

average temperature of all sites is 65.6oC. No sites have a

temperature of 100oC or more.

Slightly smaller than West Virginia, Croatia is the richest

of the Balkan countries with a 1999 per capita income of

US$5,584. Following its independence from Yugoslavia

in 1991, Croatia was immediately plunged into the conflict

over Bosnia-Herzegovina, until the March 1994 cease fire.

Following the death of nationalistic President Tudjman in

1999, and the defeat of his party in the 2000 elections, a

new government has taken the reins. The new Croatian

Government’s economic priorities are maintaining

stability and moderate growth, completing the transition to

a market economy, and gaining admission to the World

Trade Organization (WTO), the Central European Free

Trade Agreement (CEFTA), and the European Union. 

Croatia shares borders with Bosnia and Herzegovina,

Hungary, Serbia, Montenegro, and Slovenia. 

Croatia’s 2000 GDP growth rate was 3.7%, up from 0% in

1999. Following a recession which began in 1998,

economic growth is forecasted to increase by at least 5%.

Power Summary

Croatia’s total installed capacity in January 2000 was

3911.6 MWe – 57% hydropower, 42% fossil fuel, and less

than 1% nuclear.6 The country is a net energy importer,

About 10-20% of Croatian demand for electricity has been

covered by imports. 

6 The 632-MWe Krsko Nuclear Power Plant (NPP),

located on the border with Slovenia, is jointly

owned by the two countries. Croatia and Slovenia

have failed to resolve financial and other issues

concerned with the plant. Currently, Croatia is not

using electricity from Krsko and may sell its share

of the plant. 
Geothermal Resources in the Balkans 18

Croatia’s electricity consumption, which increased from

10.9 billion kWh in 1992 to 13.6 billion kWh in 1999,

continues to exceed domestic generation. Domestic

demand increased 5% annually from 1993 to 1999. 

In order to help satisfy increased demand, Croatia plans to

build new generating capacity, which it hadn’t done since

1992. In 2000, the new government renegotiated the

terms of Enron Europe’s PPA with the previous

administration to build a 240-MWe natural gas combined

cycle plant, agreeing to complete the utility company’s

restructuring and privatization and fully liberalize the

electricity market within the next two years. In return,

Enron will build an independent power plant at Jertovec

within five years. The two sides agreed to continue the

earlier power supply agreement, but with Enron selling

electricity to Croatia at 3.79¢/kWh instead of the original

5.6¢/kWh. 

In addition, the renovation and rehabilitation of several

older plants are planned, as well as the construction of

new hydropower and coal-fired plants. All together,

including the Enron plant, an additional 1,156.5 MWe of

installed capacity is planned. Foreign loans and direct

investment are the primary sources of financing. 

Investment in the reconstruction, modernization, and

upgrade of Croatia’s generation capacities and distribution

network could total US$1 billion. 

By 2005, Croatia expects to have 4,650 MWe installed

capacity composed of 4.4 MWe geothermal, 2,467.6 MWe

fossil fuels, 2,152.0 MWe hydro, and 26.0 MWe other

renewables (JeliÉ et al., 2000).

Government / Legislation

Croatia’s power sector is state-owned. The Ministry of

Economy is the lead government institution which

develops and implements energy policy. 

Croatia’s energy sector is currently dominated by three

state-owned companies: 

1. Croatian Electricity Company (Hrvatska

Elektroprivreda [HEP]),

2. Croatian Oil and Gas Company (Industrija Nafte

[INA]), and 

3. Adriatic Pipeline (Jadranski Naftovod [JANAF]). 

Croatian Electricity Company (HEP)

HEP is responsible for the generation, transmission, and

distribution of electricity. The utility presently generates

about 95% of Croatia’s electricity, the remainder coming

from privately-owned industrial co-generation power

plants and small HPPs. Its infrastructure is old and

insufficient. 

HEP posted a 690 million Croatian kuna (US$80.1

million) net loss in 2000, due primarily to drought and the

increase in heating fuel and natural gas prices, which rose

86% and 66% respectively. The utility is owed its book
Geothermal Resources in the Balkans 19

value – 1.8 billion kuna (US$211 million) – by industry,

households, and local administrations. HEP’s CFO

forecasted in March that HEP’s net profit would be 27

million kuna (US$ 3.2 million) in 2001. 

The U.S. Agency for International Development

(USAID)-HEP Joint Electricity Reconstruction Project,

formally launched in April 2001, will restore electric

service in war-affected areas with the aim of promoting

the return of refugees to their homes. Under the initiative,

USAID will finance US$5 million worth of equipment and

construction services. HEP will provide design,

construction supervision, and electro-mechanical services

totaling US$2.1 million. 

The Government of Croatia (GOC) selected a consortium

headed by the British law firm Norton Rose, and including 

French bank, BNP Paribas, and Ernst & Young, to prepare

HEP for a sell-off later in 2001. INA is slated for a selloff in 2002. Transmission will most likely remain under

state control.

Company Act

Foreign investments in Croatia are regulated by the

Company Act.7

 Foreign legal entities in Croatia are

allowed to acquire the right to exploit natural resources or

other assets of interest to Croatia; and take part in BOT

and BOOT (Build-Own-Operate-Transfer) deals. IPPs are

allowed under Croatian law. 

The right to exploit natural resources and other resources,

and the right to conduct certain other business activities,

are granted by concession. A concession may be granted

to a domestic or foreign legal or natural person for a

period of up to 99 years.

Foreign persons who conduct business activities in the

Republic of Croatia may, on the basis of reciprocity and

without any restrictions, acquire ownership rights to real

estate. A foreign person may also lease real estate.

Investment Incentives Law

Enacted in July 2000, the Investment Incentives Law

establishes employment and tax incentives for new

investment. Most notable, the Law offers the following tax

reductions for investments satisfying criteria set down in

the law:

• 7% corporate tax for 10 years for companies

that invest 10 million kuna (US$1.2 million)

and create 30 new jobs;

7 Croatia has adopted a more sophisticated approach

to the legal and regulatory framework for foreign

investment with the presumption being that, since

foreign investors receive national treatment, no

special legislation is required. Rather, the rights and

protections for foreign investors are implicit and

incorporated into domestic laws.
Geothermal Resources in the Balkans 20

• 3% corporate tax for 10 years for companies

that invest 20 million kuna (US$2.3 million)

and create 50 new jobs; and

• 0% corporate tax for 10 years for companies

that invest 60 million kuna (US$7 million)

and create 75 new jobs.

The Law also provides a one-time lump sum subsidy of

15,000 kuna (US$1,800) to the new investment for each

new employee. Investors may also receive assistance from

the GOC in offsetting costs of employee re-training. The

GOC may also be able to contribute real estate (or permits

or infrastructure) to an investment either cost-free or on a

preferential basis. Finally, the GOC will allow the

importation of capital equipment for the investment on a

duty-free basis.

No Specific Law for Geothermal

Croatia has no specific geothermal legislation. No

guidelines exist for geothermal exploration permits or

licensing geothermal exploitation. Geothermal licensing

is issued by the state. 

The GOC supports investment in geothermal projects

through price indexing (price in relation to other energy

sources) and the free utilization of existing wells. 

Financing is available for geothermal projects as loans

with commercial interest rates and grants. 

Program of Geothermal Energy Utilization, (GEOEN)

In 1997, the GOC created the Program of Geothermal

Energy Utilization, (GEOEN), as part of the National

Program of the Croatian Energy Sector Development and

Organization. GEOEN’s objective is to promote

knowledge and experience in the geothermal energy

sector. Institutional coordination is carried out by the

Energy Institute “Hrvoje Pozar.” Other participants

involved in program are: the Ministry of Economy, the

Ministry of Development and Reconstruction, the Ministry

of Science and Technology, the State Administration for

Environmental Protection, HEP, INA, and the Faculty of

Mining Geology and Petroleum Engineering. GEOEN’s

second phase, currently in progress, includes pilot projects

and implementing a geothermal energy utilization

program.

The future development of geothermal energy in Croatia

has been defined within the GEOEN Program, according

to three possible scenarios:

1. Slow introduction of new technologies and

insufficient government activities in the energy

sector reform and restructuring;

2. Implementation of new technologies, made possible

by technology transfer resulting from Croatia

joining the European Union and supported by state

incentive mechanisms; and
Geothermal Resources in the Balkans 21

3. Compilation of highly technological and ecological

features, characterized by a strong influence of the

environmental protection concept to global

economic and energy development.

Geothermal Sites / Projects

Croatia can be divided into two geological regions. In the

southeastern part, which belongs to the Dinaride area,

Mesozoic carbonate rocks prevail. Towards the northeast,

in the area belonging to the Pannonian Basin, Quaternary

and Tertiary sedimentary rocks predominate, overlying

crystalline bedrock and occasional Mesozoic sedimentary

rocks. 

Croatia is endowed with significant geothermal potential

in the Pannonian area. The temperature gradient in this

region ranges from 0.03 to 0.07°C/m. The terrestrial

heat-flow density is also high, ranging from 60 to 100

mW/m2, and occasionally up to 120 mW/m2 (KovaÖiÉ,,

2000). INA, in the process of exploring for oil and gas,

has discovered, explored, and tested geothermal fields

since 1976. 

More than 50 deep boreholes have been drilled through

geothermal aquifers in the Pannonian region.

Temperatures are 40-170°C. Some geothermal fields have

been defined, but the majority require further

investigation. A small fraction of known geothermal

energy potential in Croatia is currently under exploitation. 

As of 2000, Croatia had 113.9 MWt of installed capacity. 

The bulk – 77.24 MWt – is used for bathing and

swimming, followed by 36.66 MWt for space heating

(JeliÉ et al., 2000). The country’s direct use potential from

tested reservoirs is estimated at 815 MWt. 

Croatia’s potential markets for geothermal are district

heating, greenhouses and agriculture, fish farming, health

spas, swimming pools, and cascaded uses, and to a lesser

extent – industrial processes (e.g., drying, pasteurization,

and fruit and vegetable processing), and combined space

heating and cooling. 

Croatia currently has no electricity generated from

geothermal resources. Estimated power generation from

tested reservoirs with temperatures higher then 120oC is

approximately 28 MWe (GEOEN). Total power

generation potential using the data included in the

database is 47.87 MWe. It is estimated that geothermal

energy could produce 3.9% of Croatia’s total electricity. 

Unfortunately, the most promising geothermal fields for

power generation, located in northern Croatia, are

relatively far (10-15 km) from potential consumers. 

Northern Croatia is also well supplied by a natural gas

pipeline, leaving little incentive to develop geothermal

resources for power generation at this time. 

Plans are underway to build Croatia’s first geothermal

power plant – a 4.4 MWe combined heat and power plant 
Geothermal Resources in the Balkans 22

in Velika Ciglena – by 2005. The plant would be

increased to 13.1 MWe by 2015. 

The Database of Geothermal Resources in the Balkans

contains information on 28 specific geothermal sites or

projects in Croatia. See Table 4 for a complete listing of

the sites, their development status, temperature (oC), and

electric power generation potential. A complete

description of each site, to the extent information is

available, is included in the Appendix.

Croatia’s highest enthalpy geothermal resource identified

to date is Velika Ciglena with a temperature of 170oC. 

The average temperature of all sites is 75.9oC. Four sites

have a temperature of 100oC or more.

The Former Yugoslav Republic of Macedonia (FYR

Macedonia) is a landlocked country slightly larger than

Vermont. It is located on a major transportation corridor

from Western and Central Europe to the Aegean Sea, and

from Southern Europe to Western Europe. FYR

Macedonia shares borders with Albania, Bulgaria, Greece,

Serbia (Kosovo), and Montenegro. 

International recognition of FYR Macedonia’s

independence from Yugoslavia in 1991 was delayed by

Greece’s objection to the new state’s use of what it

considered a Hellenic name and symbols. Greece finally

lifted its trade blockade in 1995, and the two countries

normalized relations. 

United Nations sanctions against Yugoslavia took away

60% of the country’s export market, resulting in US$3.5

billion in losses. Economically, despite a very rough start

from blockades and loss of export markets, FYR

Macedonia has made significant progress toward

westernizing its economy and furthering its goal of

integration with Euro-Atlantic structures. 

By mid-1998, 95% of industrial, commercial and mining

enterprises had been privatized. In the same year, FYR

Macedonia’s exports increased faster than imports for the

first time since independence, and foreign investment

exceeded all previous years’ Foreign Direct Investment

(FDI) combined. 

For 2001, the Government of FYR Macedonia predicts

that inflation will be maintained at 2.2% and that GDP

will grow by 6%. 
Geothermal Resources in the Balkans 25

A multi-ethnic society in a volatile region, FYR

Macedonia faces internal challenges. During NATO’s

bombing campaign, almost 260,000 Kosovar refugees

arrived in the country. Most returned to Kosovo after June

2000. 

More recently, fighting broke out between the Albanian

National Liberation Army (NLA) and Macedonian

security forces in Tetovo, the country’s second largest

city, located in northwestern Macedonia. Among the

NLA’s demands are to change the Macedonian

constitution to give Albanians equal status with

Macedonians as a “state-forming” people and to place the

Albanian language on par with Macedonian as an official

language. The NLA denies wanting to create a “Greater

Albania” or a “Greater Kosovo.” International

organizations are working with the Macedonian

Government to address the Albanian minority’s concerns

in the political arena. 

Power Summary

FYR Macedonia has an installed capacity of 1,494 MWe –

423 MWe hydroelectric and 1,071 MWe thermal. The

country lacks oil, gas, or high quality coal resources. 

Wood is used extensively for home heating. The country

imports around 40% of its energy consumption – mostly

petroleum, and is beginning to import natural gas from

Russia. 

After declining following FYR Macedonia’s independence

and the economic contraction resulting from the UN and

Greek embargoes, energy demand is expected to increase

commensurate with GDP, at approximately 3% annually. 

The state utility, Elecktrostopanstvo na Makedonija

(ESM) forecasts that electric demand will reach 7,229

GWh in 2005, up from 6,329 GWh in 1996. Using these

projections, no additional generating capacity is needed

until about 2003. Priority will be given to developing

domestic resources, e.g., hydropower. Concessions or

BOT will be used.

FYR Macedonia is strategically located in the heart of the

Balkans, which places it in the middle of critical energy

transmission links. The US$85-100 million Trans-Balkan 

Electric Transmission System Interconnection Project,

which will connect the electric grids of Macedonia,

Bulgaria, and Albania, has high priority within the

Stability Pact. 

Under the World Bank US$39.6 million Power System

Improvement Project scheduled for completion in 2005,

ESM will rehabilitate the country’s six largest

hydropower plants; improve the utility’s Energy

Management System including controls, dispatch center,

and communications; and begin rehabilitating the

electricity distribution system. The project will also

facilitate the development of independent power

producers, and the eventual reintegration of ESM into

UCTE. 
Geothermal Resources in the Balkans 26

The development of alternative domestic energy sources 

received considerable attention in recent years, including

numerous efforts to assess and develop geothermal energy

for greenhouses and space heating. Such activity was not

extensive, however, due to economic constraints.

Government / Legislation

FYR Macedonia’s power sector is controlled by the state

with ESM as the principal entity. State control is

principally in the areas of investment planning,

management selection, and pricing. Several ministries and

the Council of Ministers have various responsibilities.

Elektrostopanstvo na Makedonija (ESM)

ESM manages the production, transmission, and

distribution of energy in FYR Macedonia. 

Council of Ministers

The Council of Ministers sets electricity prices based on a 

request from ESM through the Ministry of Economy. The

Council also makes top management appointments for

ESM and ratifies major investments by ESM. 

Energy prices generally cover costs. Under an EBRD loan

to FYR Macedonia, a target pattern of real electricity price

increases in German Marks (DM) has been established. 

District heating prices are comparable on a heat

equivalent basis to West European prices for light fuel oil

or natural gas supplied to households, averaging around

$35/Gcal. 

Regarding prices for geothermal energy, one of the most

difficult problems is to overcome the conception by

consumers that geothermal energy is free of charge and

that therefore they do not have to pay for its use, apart

from distribution and maintenance costs (Popovska et al.,

1995). 

According to a new state regulation introduced in 1999,

the price of geothermal energy is set relative to the prices

of other sources (e.g., fossil fuels and electricity), and

determined by m3 rather than by kWh used heat. 

According to the regulation, energy of geothermal origin

has a certain value and price which should be covered by

users. The value is composed of the costs for exploration

and investigation, project development, and system

exploitation and maintenance. The price should be not

lower than 40% or higher than 60% of the heat unit of a

heavy oil origin. In order to ensure proper use of the

temperature difference on disposal, used energy should not

be calculated in energy units but in cubic meters of the

used thermal water. The regulation has not been properly

applied (Popovski and Lund, eds., Popovski and

Popovska-Vasilevska, 1999).

Ministry of Economy

The Ministry of Economy has principal oversight

responsibility for the energy sector, and reviews and
Geothermal Resources in the Balkans 27

approves ESM’s investment plans. It recommends to the

Council of Ministers the tariffs for electricity, based upon

the proposals of the interested companies. In the special

case of district heating prices, the Ministry can approve

these prices without the intervention of the Council of

Ministers. It is involved in the selection of top

management for ESM.

Under proposed restructuring, the Ministry of Economy

would be responsible for policy and oversight. A new,

independent regulatory system would be created which

would be responsible for setting prices for transmission,

distribution, and power generation, by both IPPs and

ESM.

Ministry of Development

The Ministry of Development reviews and comments on

major investment plans, especially those of ESM, and may

also review and comment on pricing proposals. 

Ministry of Finance

The Ministry of Finance may review and comment on

pricing proposals as well. 

The legal framework for the energy sector in FYR

Macedonia is being developed. Two key pieces of

legislation affecting the energy sector are the proposed

Energy Law and the proposed Law on Public Enterprises. 

Energy Law (draft)

The draft Energy Law establishes a basis for the operation

of energy companies. It establishes that, at least initially,

energy utilities are required to be public enterprises with

majority Government ownership. Private companies

would be allowed to operate in the sector, including the

electricity subsector, with the agreement of ESM on

obtaining access to the transmission system. 

If agreement cannot be obtained, the Ministry of Economy

would be allowed to prescribe the terms and conditions of

an agreement designed to facilitate participation by IPPs in

power generation. There is significant potential for IPPs

both as small scale hydropower plants and as cogenerators. The Energy Law also requires the 

Government to develop a comprehensive Energy Plan.

Law on Waters

The Law on Waters applies to “spring, stream, standstill

and underground waters, then to the atmosphere water, the

drinking water and the waste water, to both the beds and

the banks of the water streams, the torrents, the lakes and

the accumulations, as well as to the thermal and mineral

waters, unless otherwise determined by another Law.” 

Pursuant to Article 132, legal persons who produce

electric power pay compensation for the used water for

every produced kW per hour. Pursuant to Article 153,
Geothermal Resources in the Balkans 28

water is given for use by concession for the production of

electric power. 

The Ministry of Agriculture, Forestry, and Watereconomy supervises this Law and its regulations.

No Specific Law for Geothermal

FYR Macedonia has no specific geothermal legislation. 

The ownership of geothermal resources has not been

defined. 

General legislation on geothermal resources is covered by

the Law for Mineral Resources (24 March 1999) which is

governed by the Ministry of Economy. 

Pursuant to Articles 85 and 86 of the Law, a concession

for geothermal resources may be granted to any foreign or

local legal or physical entity which possesses financial

resources and equipment to invest in, develop, and exploit

such resources. Pursuant to Article 85 of the Law, a

concession is granted by the Government of the Republic

of Macedonia by submitting a written application or a

letter of intent. The following information is required: 

• Name and address of the legal or physical entity,

and description of the company;

• Company bank statement;

• Location and size of geothermal area;

• A topography map (scale of 1:25,000) in which the

boundaries of the area are outlined;

• General geology of the area;

• General hydrogeology and geothermal

characteristics of the area; and

• Brief description of planned utilization of resource.

The Government will submit the concession application to

the Ministry of Economy for further consideration. The

Ministry will prepare a decision on which basis the

Government shall issue the concession. 

A concession for geothermal exploration may be granted

for four years with a possible four-year extension. A

concession for geothermal exploitation may be granted for

30 years with a 30-year extension. A concession is limited

to an area of 200 km2. The area size is reduced after the

first year to 50% of the area granted, and by 15% of the

remaining area in each successive year of exploration. 

There is no limit to the number of concessions a company

may have. 

Fees are as follows:

• Area fee – US$50/km2

 per year for exploration;

US$1,000/km2 per year for exploitation;

• Royalty – 0.2-2% of the value of the commercial

product

The Government of FYR Macedonia also supports

investment in geothermal projects through price indexing
Geothermal Resources in the Balkans 29

(price in relation to other energy sources), free utilization

of existing wells, tariffs, and a special selling price. 

Financing is available for geothermal projects as loans

with commercial interest rates.

Geothermal Sites / Projects

FYR Macedonia is located in the central part of the Balkan

Peninsula, in the geothermal zone which runs from

Hungary in the north and Italy in the west, and crosses

Greece, Turkey, and beyond to the east. Specifically, the

country is situated in the southernmost part of the

Bosnian-Serbian-Macedonian geothermal area which

includes the mountains of the internal Dinarides and parts

of the Serbian-Macedonian massif. 

The country contains six geotectonic zones: the CukaliKrasta zone, the West Macedonian zone, the Pelagonian

horst anticlinorium, the Vardarian zone, the SerboMacedonian massif, and the Kraisthide zone. Geothermal

manifestations are mainly connected to the Vardarian zone

where the earth’s crust is about 32 km.

FYR Macedonia has 18 geothermal fields. More than 50

thermal springs, boreholes, and wells discharge almost

1,400 l/s water with temperatures of 20-79oC. Thermal

waters are primarily bicarbonate with equal amounts of

Na, Ca and Mg. Dissolved minerals range from 0.5 to 3.7

g/l. All are of meteoric origin (Dragasevic, 1974).

FYR Macedonia’s hot springs have been used since

Roman times for bathing. More recently, in 1963, the first

geothermal greenhouse in the world was built near

Bansko. The 1979-1984 energy crisis stimulated more

geothermal exploration. Six large greenhouse heating

projects, a rice drying project, a complete hotel heating

project, and several smaller heating installations were

developed during this period. Some have been abandoned

or operate below their design capacity. Development

ceased after independence and during the U.N. and Greek

embargoes. The bulk of Macedonia’s low-enthalpy

geothermal resources are used for greenhouses. 

As of 2000, Macedonia had an installed capacity of 81.2

MWt producing 510 TJ/yr or 142 GWh/yr. The capacity

factor is 20%. One well has been drilled; 55 person-years

and US$15 million have been invested in geothermal

development (Lund and Freeston, 2000).

FYR Macedonia’s geothermal development objectives to

2010 are: 

• The reconstruction, modernization, and

optimization of existing projects; 

• The addition of new industrial and residential

projects in the Kochani geothermal system;

• Connecting additional hotels to the Bansko heating

system; and 

• Completing the water center at Negorci and the

medical center in the Katlanovo Spa (Popovski and

Popovska-Vasilevska, 1999). 
Geothermal Resources in the Balkans 30

In addition, the country will draft a national geothermal

master plan with Italian assistance. 

Macedonia has approximately 2,200 MWt in unexploited

low-enthalpy geothermal resources (GEOTHERNET). 

The country’s potential markets for geothermal are district

heating, greenhouses and agriculture, and cascaded uses,

and to a lesser extent – fish farming, health spas,

swimming pools, and industrial processes. 

FYR Macedonia has no electricity generated from

geothermal resources. The country’s estimated power

generation potential is 200 MWe.8 Total power generation

potential from the specific sites included in the database is

unknown. 

The Database of Geothermal Resources in the Balkans

contains information on 32 specific geothermal sites or

projects in FYR Macedonia. See Table 5 for a complete

listing of the sites, their development status, temperature

(oC), and electric power generation potential. A complete

description of each site, to the extent information is

available, is included in the Appendix.

FYR Macedonia’s highest enthalpy geothermal resource

identified to date is Gornitchet with a temperature of

150oC. The average temperature of all sites is 56.7oC. 

Twelves sites have a temperature of 100oC or more.

The furthest west of the former Yugoslav republics,

Slovenia declared its independence in 1991. The country

has done well, averaging 4% annual growth since 1993,

and is one of the most advanced countries in the Balkans

with a GDP per capita comparable to several EU member

countries. In information technology, Slovenia is at the

forefront of the Internet revolution, with the highest

concentration in Europe of Internet connections per

inhabitant or per server. Slightly smaller than New Jersey,

Slovenia borders Austria, Croatia, Italy, Hungary, and the

Adriatic Sea.

Slovenia is currently aligning its political and economic

systems with EU requirements. Subject to continued

sound macroeconomic management, the prospects for

Slovenia appear good. The country’s ability to sustain

high growth rates with price stability, however, will

increasingly depend on its capacity to reinvigorate the

structural reform agenda. The accession process to the EU

is helping in this respect, encouraging the authorities to

advance key structural reforms. Slovenia is well

positioned to be among the first Central and Eastern

European countries to become a full member of an

enlarged EU (World Bank, Country Brief).

Power Summary

Slovenia has an installed capacity of 2,517 MWe – 1,117

MWe fossil fuels, 768 MWe hydropower, and 632 MWe

nuclear.9

9 Due to an unresolved dispute with Croatia over

restructuring and operational costs, since July 1998,

the 632-MWe Krsko NPP has delivered all its

electricity to Slovenia, resulting in a power surplus. 
Geothermal Resources in the Balkans 34

The country has minimal indigenous reserves of oil and

gas, and is dependent upon imports from Croatia, Algeria,

and Russia for over half of its total primary energy supply.

The country has proven lignite coal reserves, and also

imports coal from Indonesia, Germany, and the Czech

Republic. In the future, natural gas will be substituted for

coal and hydropower will be prioritized. 

With an estimated 8,800 GWh/yr of technically feasibly

hydropower potential, only a third of which has been

developed to date, and a desire to minimize import costs,

increased hydroelectric power generation is a strategic

objective of the Government of Slovenia’s (GOS) energy

policy. An additional 1.5 TWH of electricity by 2010 is

planned, requiring that 70% of the potential sites are

exploited. In addition to large HPPs, small, mini, and

micro hydro plants are being constructed. 

The Government of Slovenia’s vision for the energy sector

is outlined in its “Strategy of Efficient Use and Supply of

Slovenia” which was approved in 1995. The main

objectives of the Strategy are to maintain a sustainable

level of electric power production in the present thermal

power plants and newly constructed capacities, to

disengage and decommission nuclear power production, to

increase natural gas use by commercial and residential

users, to maintain the rate of domestic coal use, and to

increase the share of renewable energy sources.

Based on high and low demand forecasts, four supply

scenarios to 2010 have been prepared using three sets of

basic assumptions: high and low rates of economic

growth; larger and smaller investments in energy

conservation and efficiency; and different supply options. 

According to the low economic growth scenario model

designed by the Ministry of Economic Affairs (MEA),

electric consumption could grow 0.5% per year from 1995

to 2010. The high economic growth scenario forecasts a

growth rate of 2.3% per year in the same period. 

The GOS’s 10-year expansion program for 1997-2006

calls for a total of US$1.5 billion in investment financing

(Energy Sector Management Assistance Programme,

1999). 

For the transmission and distribution system, investment

plans up to 2010 include the modernization of the national

dispatching and local distribution control centers,

renovation of the transmission grid, better control of

reactive power in the system and the completion and

renovation of the east-west 400 kV transmission lines with

a connection to Hungary and a 400 kV substation. 

By 2005, Slovenia’s projected installed capacity will be

2,870 MWe – 1,345 MWe fossil fuels, 883 MWe

hydropower, and 10 MWe geothermal. 

A Westinghouse PWR which operates to

U.S. Nuclear Regulatory Commission safety

standards and regulations, the Krsko NPP is

scheduled for decommission in 2023. 
Geothermal Resources in the Balkans 35

Increasing renewable energy is a long-term strategic goal,

i.e., increasing the use of hydropower, biomass,

geothermal, solar, and waste-to-energy sources for

electricity generation. The GOS promotes renewable

energy via tax incentives.

Government / Legislation

Slovenia has a well-developed, structured legal system. 

The GOS’s operational goal is to have the entire energy

sector in full conformity with EU standards by the end of

2002.

Slovenia’s energy industry is divided according to

generation, transmission, and distribution and is primarily

publicly-owned. 

Ministry of Economic Affairs (MEA)

The MEA is responsible for planning long-term energy

investments and operational management. It heads the

Agency of the Republic of Slovenia for Efficient Use of

Energy and the Inspectorate of the Republic of Slovenia

for Energy, Mining, and Construction. 

Elektro-Slovenija (ELES)

State-owned ELES is in charge of energy transmission and

dispatching as well as electricity trade and technical

relations with the West European interconnected grid

UCTE. The Slovenian power system is part of the UCTE

network, with interconnecting links to Italy, Austria, and

Croatia. ELES is also formally responsible for establishing

purchase and sales contracts between power sector

enterprises. 

Public companies buy power from ELES, which was, prior

to the new Energy Law, the only company authorized to

purchase and transfer electricity from generators. ELES in

turn supplies the country’s five largest industrial

consumers through direct sales. Electricity is otherwise

marketed through five regional distributors (Elektro

Ljubljana, Elektro Maribor, Elektro Celje, Elektro

Gorenjska, and Elektro Primorska). . There are eight

generating companies. 

Trade and Investment Promotion Office (TIPO)

Companies making foreign direct investments in Slovenia

may be eligible for financial assistance in the form of

grants from TIPO. Incentives are provided to projects that

create at least 100 new jobs; or 20 new jobs in less

developed areas or where investment is made in R&D. 

Foreign investors are treated legally the same way as

domestic companies and enjoy the same rights and

obligations as domestic Slovenian companies. Foreignowned companies may own property in Slovenia.

Phare Programme

Supported by the EU, the Phare Programme granted

Slovenia i228 million (US$203 million) between 1992-
Geothermal Resources in the Balkans 36

1998, and plans to give a further i560 million (US$499.6

million) by 2002. 

With a zero-interest loan from the Phare Programme, the

MEA energy efficiency agency created an energy

efficiency investment fund in January 1998 to develop the

potential of decentralized energy supply based on

cogeneration and utilization of renewable energy sources.

Managed by the Austria National Bank, the fund provides

industry and institutions with a limit of i500,000

(US$446,000) per project under attractive interest rates. 

The Phare Programme is the main channel for the EU’s

financial and technical cooperation with the countries of

central and eastern Europe. The fundamental objective for

Phare in Slovenia is to help the country join the EU as

soon as possible.10

Energy Law

Enacted in September 1999, the Slovenian Energy Law

ensures full harmonization with the energy-related laws

and practices of the EU’s electricity market directive

especially with respect to environmental protection and

the establishment of a market.

Under the Law, Slovenia’s electricity market will be

opened for domestically produced electricity. 

Specifically, by January 2001, all electricity users with at

least 41kV connected power, all of industry, and most

services (about 62% of the market) will be able to freely

choose domestic suppliers, and in January 2003, to import

electricity given national reciprocity. 

Slovenia’s internal electricity market will be opened to

foreign players on 1 January 2003, but only on a

reciprocity principle, i.e., if Slovenia has not entered the

EU by then, the date for integration into the EU electricity

market will be extended accordingly. The future

electricity market will be comparable to the United

Kingdom model. 

Article 119a of the Law allows public electricity

producing or distributing enterprises to privatize. Utilities

engaged in electricity transmission, operating the

electricity transmission network, or operating the

organized electricity market, as well as the Krsko NPP, are

specifically exempted from privatization under this Law. 

The Law also foresees the establishment of the Energy

Agency, an independent regulatory body, which will be

responsible for setting prices for electricity, fuel, and

services. 

10 The Phare partner countries fall into two basic

groups: those that have applied to become members

of the European Union (Bulgaria, the Czech

Republic, Estonia, Hungary, Latvia, Lithuania,

Poland, Romania, Slovakia and Slovenia), and those

that have not (Albania, Bosnia and Herzegovina,

and FY Macedonia). (Croatia was suspended from

the Phare Programme in 1995.) 
Geothermal Resources in the Balkans 37

The GOS introduced a new tariff system on 15 December

1998 and value-added tax (VAT) on 1 July 1999. It has

raised electricity prices several times since. In November

2000, prices for households increased 4% (roughly in line

with inflation); for other users, 2%. Prices for industrial

consumers rose more modestly as Slovenian industry

already pays more than its EU counterparts on average.

Electricity prices in Slovenia are generally higher than in

the EU. 

Public Trading Services (PTS) Act

The PTS Act allows for concession arrangements but

refers to sectoral legislation to define for which particular

services concessions may be granted. Foreign investors

may obtain concessions for the exploitation of renewable

and non-renewable natural and public goods.

No Specific Law for Geothermal

Slovenia has no specific geothermal legislation. 

Geothermal licensing is issued by the state. Some

financing is available for geothermal projects as loans with

commercial rates, grants, and project financing. 

Geothermal Sites / Projects

With the Julian and Karawanken Alps in the north, and the

Dinaric Alps in the south, Slovenia is extremely

mountainous. The country’s complicated tectonic and

stratigraphical setting is reflected in the Earth’s thermal

field. In the upper few kilometers of the crust,

temperatures increase from southwest to northeast. 

The geothermal conditions in western Slovenia are

influenced by the large crustal thickness in the Outer

Dinarides and Southern Alps. Thermal springs in this area

located southwest of the Pannonian Basin, have

temperatures of less than 45oC. Northeastern Slovenia is

affected by the high enthalpy geothermal system, Termal

II, in the Pannonian Basin. At depths of more than 2500

m, thermal fluids reach temperatures of 100-200oC. About

6% of the country’s total area, or 3200 km2, is promising

for geothermal development. 

Geothermal resources in northeast Slovenia total about 7 x

106 TJ. East Slovenia’s geothermal resources total 7.66 x

106

 TJ (Rajver et al., 1995). 

Geothermal exploration for high enthalpy resources on

Slovenia began after the first energy crisis in 1973. 

Systematic geothermal investigation aimed at acquiring

rock temperatures and their gradients, measuring thermal

conductivity, and identifying the concentration of

radiogenic elements in the rocks began in 1982. From

1995 to 2000, 18 wells with a total depth of almost 12 km

were drilled (Kralj and Rajver, 2000). Forty-three personyears and US$16.08 million have been invested in

geothermal development (Lund and Freeston, 2000). 

Presently, hydrogeothermal and geophysical investigations

are needed in general, especially in western and central
Geothermal Resources in the Balkans 38

Slovenia where there is an interest in developing new

recreational facilities. A cost-benefit analysis to determine

the most rational use for proven resources is also needed.

As of 2000, Slovenia had an installed capacity of 42 MWt

producing 196 GWh/yr. Geothermal resources are

primarily used for thermal spas and recreation, space

heating and cooling, greenhouses, industrial processing,

and heat pumps. Reinjection is not currently used. 

Slovenia has an additional 64 MWt in unexploited, proven

resources. 

Slovenia’s potential markets for geothermal are district

heating, health spas, swimming pools, and cascaded uses,

and to a lesser extent – greenhouses and agriculture, fish

farming, and industrial processes. 

Slovenia has no electricity generated from geothermal

resources. A 1-MWe plant (probably binary) is planned at

Lendava and should be operational by the end of 2002. 

The Database of Geothermal Resources in the Balkans

contains information on 52 specific geothermal sites or

projects in Slovenia. See Table 6 for a complete listing of

the sites, their development status, temperature (oC), and

electric power generation potential. A complete

description of each site, to the extent information is

available, is included in the Appendix.

Slovenia’s highest enthalpy geothermal resource identified

to date is Ljutomer with a temperature of 175oC. The

average temperature of all sites in Slovenia is 33.6oC. 

Two sites have a temperature of 100oC or more.

Created by the dissolution of the Socialist Federal

Republic of Yugoslavia (SFRY) in 1992, the Federal

Republic of Yugoslavia is composed of two republics –

Serbia and Montenegro, and two autonomous provinces –

Vojvodina and Kosovo (which includes Metohija). 

Kosovo effectively became a U.N. protectorate in June

1999. 

Combined, Serbia and Montenegro are slightly smaller

than Kentucky. Serbia is slightly larger than Maine;

Montenegro is slightly smaller than Connecticut. The

country shares borders with Albania, Bosnia and

Herzegovina, Bulgaria, Croatia, and Hungary. 

How long Yugoslavia retains its current structure is

uncertain. President Djukanovic wants Montenegro to

break away from the existing federation, then negotiate a

much looser confederal arrangement, sharing only foreign

affairs, defense, and a common currency with Serbia. 

Montenegro’s parliamentary election of 22 April,

however, was very close and did not indicate a clear

popular mandate for independence. Yugoslav President

Kostunica is against any break-up and favors a much

closer relationship, one that would include economic

affairs.
Geothermal Resources in the Balkans 42

The break-up of SFRY in 1992 was economically

disruptive as trade ties between the six former republics

were severed. In addition, Milosevic’s repeated attempts

to build a “Greater Serbia,” conduct ethnic cleansing

campaigns, and wage wars have prevented Serbia and

Montenegro’s economies from recovering. The country

has 800,000 refugees, an unemployment rate of 40%, a

shrinking GDP, US$30 billion worth of damage caused by

the NATO bombing, and is US$12 billion in debt.

Following the democratic election of President Kostunica

in October 2000, the EU and U.S. lifted their sanctions

and oil embargoes against Serbia. The U.S. established

diplomatic relations with the Federal Republic of

Yugoslavia on 17 November 2000. Many international

financial institutions, e.g., the World Bank, IMF, EU,

EBRD, and USAID are developing assistance programs

for Yugoslavia. 

The Government of Yugoslavia hopes the arrest of

Milosevic on 1 April persuades the U.S. administration to

recommend the release of US$50 million in aid and back

Yugoslavia’s request for loans from the World Bank and

the IMF. The Government calculates it needs a further

US$600 million in 2001. On top of that, Serbia expects to

receive an additional US$1 billion at a donors’ conference

in May-June. 

Power Summary

Yugoslavia has a total installed capacity of 10,410 MWe –

7,430 MWe in Serbia proper, 850 MWe in Montenegro,

1,567 MWe in Kosovo, and 563 MWe in Vojvodina.11 

Coal-fired plants produce 70% of the country’s electricity

with the balance coming from hydropower. HPPs are

located on the Danube, Drina, and Morava rivers in

Serbia, and on the Moraca, Piva, and Zeta rivers in

Montenegro.

The 78-day NATO bombing campaign during the Kosovo

conflict (March-June 1999) targeted the Serbian power

sector. Fourteen power stations, two major refineries, and

many transmission facilities, including nine key oil storage

depots, were damaged or destroyed.12 

Serbia has nearly 13 billion tons of exploitable lignite

reserves, primarily located in the Kosovo coal basin, now

under UN control, and nearly 7,000 GWh of hydro

11 These are 1994 estimates. U.N. estimates are higher.

The U.N. reported total capacity for Serbia and

Montenegro at a constant 11.8 gigawatts (11,800

MW) for 1994-1997.

12 A high level executive of the State Power

Corporation of China, currently reconstructing

power facilities damaged by NATO bombing in

1999, traveled to Belgrade in August 2000 to assess

future cooperation.

potential. With such resources, Serbia should be in a

position to export electricity again by 2002-2003. 

According to power company executives, the Serbian

power system has been severely neglected since the early

1990s. Due to mismanagement, corruption, lack of

maintenance, and drought, the Serbian power system was

near collapse by October 2000. During one of the worst

blackouts in December, power for most homes was shut

off 8-18 hours a day. 

Gross consumption in Serbia in 2000 was 33.3 GWh;

production was 32.9 GWh. The existing plants are based

on U.S. technology from the 1950s (Country Commercial

Guide, 1997). 

In the past several years, electricity demand increased at

an average rate of more than 5% per year. According to

Serbian power company forecasts, gross electricity

consumption in Serbia will increase at an average yearly

rate of 2.1% by the middle of next decade. 

Government / Legislation

The majority of Serbia and Montenegro’s electricity

generation, transmission, and distribution is carried out by

two state-run companies.

Yugoslavia plans to privatize its power sector within the

next two years. 

Elektroprivreda of Serbia (EPS)

EPS is active in Serbia and Vojvodina Autonomous

Province. EPS manages one transmission company

(Elektroistok), 11 distribution companies, and seven

public power generation companies. The responsible

authority is the Ministry of Mining and Energy of the

Republic of Serbia. 

EPS’s Managing Board defines the structure of the tariff

system, according to the Law on Electric Power Industry,

The Ministry of Trade approves price changes. Kept

artificially low by the Government to subsidize all parts of

the economy, electricity prices will be increased to cover

generating costs and bring a reasonable profit.13 

Elektroprivreda of Montenegro (EMK)

EMK is a small company, with one coal-fired power plant

and two large hydroelectric plants.

Kosovo Electricity Company (KEK)

KEK is the sole electricity service provider in Kosovo. 

The United Nations Mission in Kosovo (UNMIK) Public

Utilities Department (PUD) has regulatory, supervisory,

13 In Vojvodina, where there is a well developed

natural gas distribution network, households often

heat with electricity, rather than the more-effiecient

natural gas, because it is cheaper. 
Geothermal Resources in the Balkans 44

and management control responsibilities, including

oversight of organizational structure, staffing levels,

budget, and government subsidies for KEK. 

Having dealt with emergency repair and maintenance,

UNMIK is developing a comprehensive strategy to

address Kosovo’s long-term energy needs. World Bank

consultants are expected to begin a 12-month energy

sector study of Kosovo in April 2001. 

Serbian Law on Electric Power Industry (“Official

Bulletin of the Republic of Serbia [RS]” No. 45/91, 67/93,

48/94, 69/94, and 44/95)

The Electric Power Industry Law defines in detail

electricity supply industry’s activities which cover the

generation, transmission, and distribution of electricity. 

Serbian Law on Resources owned by the Republic

(“Official Bulletin of RS” No. 53/95, 3/96, 54/96, and

23/97)

Under the Resource Law, resources of common interest

(e.g., natural resources, public goods) may be exploited by

concession or by the right of usufruct.14

Serbian Law on Concessions (“Official Bulletin of RS,”

No. 20/97)

The Concession Law of the Republic of Serbia outlines a

general frame or common rules for all kinds of

concessions. Detailed conditions for pursuing a concession

are dealt with in special laws, e.g., the Law on Mining, the

Law on Electric Power Industry, the Law on Railways,

and the Law on Roads. The Concession Law regulates the

execution of projects on the basis of BOT and may be

granted for a period of up to 30 years. A concession is

granted through a public bidding process. 

A foreign national may build, manage, and use for no

longer than 20 years an object, facility, or plant as his own

company or infrastructure. For infrastructure projects, the

approval can be given for up to 30 years (“Official

Bulletin of RS,” No. 6/90).

The Ministry of Mining and Energy of the Republic of

Serbia, a competent local government agency (town and

municipality), or an interested party through the Agency

for Investment in Activities of Concern to the Republic

would recommend a concession to the Government of the

Republic of Serbia. 

The Government of Serbia passed a Decree on granting a

concession, under public bidding, for exploring,

exploiting, and developing the geothermal field in Bogatic

municipality. 14 Usufruct is the right to enjoy the use and advantages

of another’s property short of destruction or waste

of its substance. 
Geothermal Resources in the Balkans 45

Serbian Law on Foreign Investments (“Official Bulletin of

RS” No. 79/94 and 29/96)

The Law allows investments by concessions, including

BOT projects, with the condition for foreign investments

being reciprocity. In the energy and electricity sector, the

Law does not provide for special limitations or constraints

to foreign investments in Yugoslavia. Foreign investments

are protected in case of subsequent change of regulations

in Yugoslavia. 

Firms established by foreign capital are exempt from

profit tax for 72 months after entry in Serbia and 60

months in Montenegro. If a firm is located in a free zone,

this tax break lasts for 6 years in Serbia and 10 years in

Montenegro. New jobs created by investors are graced

with a two-year, 40% reduction in wage taxes in Serbia

(50% in Montenegro). Foreign citizens employed in Serbia

by foreign investors are entitled to a 50% reduction in

income tax. 

The Montenegrin Law on Special Conditions for Foreign

Companies contains some additional incentives for foreign

investment under certain circumstances.

No Specific Law for Geothermal

Serbia and Montenegro have no specific geothermal

legislation. Some financing is available for geothermal

projects as conditional loans, grants, and project financing. 

Geothermal Sites / Projects

Serbia is located in the tectonic center of the Balkan

peninsula where three main tectonic-structural systems are

developed, all of Alpine origin: the Dinarides in the west,

the Serbian-Macedonian Massif (or Rhodopes) in the

center, and the Carpatho-Balkanides in the east and

southeast. The Pannonian Basin in northern Serbia has the

most promising high-enthalpy geothermal resources. The

location of all Yugoslav oil and gas deposits, the

Pannonian region has been well investigated geologically.

Geothermal exploration in Montenegro has been minimal. 

Most of the country is covered by high and extensive

mountain massifs intersected by river gorges and deep

valleys. The high Dinaric mountains of Orjen, Lovcen and

Rumija rise steeply from the Adriatic Sea. Larger lowland

areas are located in the south, along the coast.

S. Radavanovic, the “father of Serbian hydrogeology and

geothermology” first described the area’s geothermal

resources in 1897. Thermal spring exploration began

between the two World Wars. The first borehole in the

Pannonian Basin was drilled in 1969. 

Following the energy crisis of 1974, a preliminary

evaluation of geothermal potential was completed in 1975. 

A more detailed regional exploration was conducted from

1981-1988. From 1991 to 1995, geothermal exploration

was ceased due to the breakup of the SFRY and the
Geothermal Resources in the Balkans 46

economic crisis caused by the U.N. embargo. Progress

since 1995 has been slow. 

Serbia has 60 convective hydrogeothermal systems – 25 in

the Dinarides, 20 in the Carpatho-Balkanides, 5 in the

Serbian-Macedonian Massif, and 5 in the Pannonian

Basin. Conductive hydrogeothermal systems are

developed in basins filled with Paleogene and Neogene

sedimentary rocks, and are primarily located in the

Pannonian Basin in Vojvodina in northern Serbia

(Milivojevic and Martinovic, 1999). 

Thermometric measurements in northern Serbia, down to

5 km, have produced temperatures as high as 240oC. At 3

km, temperatures close to 150oC have been found in the

Pannonian Basin, the Vardar Zone, and the SerboMacedonian Massif. Serbia’s geothermal potential or

geothermal resource base to a depth of 10 km is estimated

at 250 x 1021 J (Milivojevic, 1990). 

As of 2000, Serbia had an installed capacity of 80 MWt

producing 2,375 TJ/yr or 660 GWh/yr (Lund and Freeston,

2000). Low enthalpy resources are used for balneology

and recreation. Serbia has 59 thermal spas, many which

have been used since Roman times, and nine mineral

water bottling companies utilizing geothermal water. 

Using geothermal resources for space heating is in the

initial stages. In addition, the country has an additional

156 MWt of unexploited, proven resources.

Yugoslavia’s potential markets for geothermal are district

heating, greenhouses and agriculture, health spas,

swimming pools, combined space heating and cooling,

and cascaded uses, and to a lesser extent – fish farming,

electricity generation, and industrial processes. 

Geothermal energy is not used for power generation. 

Exploration has shown, however, that geothermal energy 

use in Serbia for power generation could provide a

significant component of the national energy balance. The

prospective geothermal reserves in the reservoirs of the

geothermal systems amounts to 400 x 106 tonnes of

thermal-equivalent oil.

Yugoslavia’s estimated power generation potential is 200

MWe.15 Total power generation potential from the

specific sites included in the database is unknown. 

The Database of Geothermal Resources in the Balkans

contains information on 100 specific geothermal sites or

projects in Yugoslavia. All are located in Serbia. See

Table 7 for a complete listing of the sites, their

development status, temperature (oC), and electric power

generation potential. A complete description of each site,

to the extent information is available, is included in the

Geothermal Resources in the Balkans 52

Conclusion

The multi-ethnic Balkans is a highly volatile region with

great potential, resources, and opportunity. 

Of the six countries of the region, four – Croatia, FYR

Macedonia, Slovenia, and Yugoslavia (specifically Serbia)

– have high-enthalpy geothermal resources which may be

suitable for power generation. Combined, the four

countries have 32 sites with a temperature of 100oC or

more. Based on political and economic stability, and a

favorable regulatory framework, Croatia and Slovenia are

the best candidates for geothermal resource development

in the short-term. More work is required in all countries,

however, in resource assessment, definition of

development goals, selection of priority areas, and costbenefit analyses.

Three items may support the development of geothermal

resources for both power generation and direct use across

the Balkans:

1. Increased international financing,

2. Greater regional cooperation, and

3. EU renewable energy directive.

Following the Kosovo campaign of 1999, under the

Stability Pact, created by the U.S. and the EU, a

significant amount of international financing began

flowing into the region. The EU will provide i2.4 billion

(US$2.1 billion) for the development of some 200 energy

projects in Southeastern Europe. The funds will play a

catalyst role in the development of the energy sectors and

attract other foreign investments.

In addition, many International Financial Institutions

(IFIs), including the World Bank, the EBRD, and the

European Investment Bank (EIB), have increased their

allocation of funds to the countries of Southeast Europe

for development projects. 

The EIB is expanding its global loans program to

Southeastern Europe to support regional cooperation. EIB

funding could cover up to 50% of the cost of specific

projects, the loans could be extended for terms of up to 25

years with a grace period of 10 years. The EIB lending

program for countries that have applied for accession to

the EU16, plus Albania and FYR Macedonia, is i3.5

billion (US$3.1 billion) annually from 2000 to 2006.

As of late 2000, the EBRD had invested US$2.13 billion

in Southeastern Europe. As part of its Southeast European

Regional Action Plan (SEEAP), the EBRD is focusing on

16 In the Balkans, Slovenia is the only “pre-accession”

country.

supporting private sector investment, including large

corporations, small and medium-sized enterprises (SMEs),

and micro-enterprises; commercial approaches to

infrastructure financing, including telecommunications,

airports, and municipal finance; and improving the

institutional capacity of the financial sector (Harris, 2000).

The EBRD launched a program in July 2000 to assist

small (less than 250 employees) businesses in

Southeastern Europe. The program is funded by US$100

million from the EBRD, and up to US$50 million, over a

four-year period, from the United States. 

An additional source of funding is the Southeast Europe

Equity Fund. Managed by Soros Private Funds

Management, the US$150-million Fund, capitalized by the

Overseas Private Investment Corporation (OPIC), will

make equity and equity-related investments in

privately-owned or privatizing companies in Southeast

Europe. The Fund will seek to generate significant capital

gains on its invested capital over a three to five year

average holding period. The Fund will be administered

through an office in Sofia, Bulgaria, and operates in

Albania, Bosnia-Herzegovina, Bulgaria, Croatia, FYR

Macedonia, Montenegro, Romania, Slovenia, and Turkey. 

Secondly, the countries of the Balkans and Southeastern

Europe are working to integrate their respective

infrastructures, including their power sectors. In

September 1999, Albania, Bosnia-Herzegovina, Bulgaria,

FYR Macedonia, Greece, and Romania agreed to establish

a unified regional electricity market (REM). The first

phase of the REM is targeted for completion by 2006. 

Finally, to date, one country of the Balkans – Slovenia – is

the closest to becoming an EU member. Once it does

accede to the EU, according to EU directives , 12% of its

total inland energy must be generated by renewable energy

sources by 2010. The Government of Slovenia may offer

support or subsidies to geothermal development after EU

accession.

The EU is also negotiating Stabilization and Association

Agreements (SAAs), a first step towards EU membership,

with several other countries in the region. The FYR

Macedonian Parliament ratified the SAA in April 2001. 

EU began negotiations with Croatia in 2000, may begin

negotiations with Albania in 2001, is conducting a

feasibility study for negotiations with Yugoslavia, and is

encouraging Bosnia Herzegovina to undertake further

reforms before talks begin.17

The most important resources explored until now are located in the northern half of the Kruje 

geothermal area, from Llixha-Elbasan in the south to Ishmi north of Tirane. The values of specific 

Temperature (oC) to 60

Geothermal Resources in the Balkans -- Appendix 9
Albania

reserves vary between 38.5 and 19.6GJ/m2.

The southern part of the Kruje area has resources of 20.63GJ/m2, evaluated by data obtained in the 

Galigati section. According to the geological conditions in this zone, its hydrogeological and 

geothermal characteristics, and referring to the geothermal springs found in Greece as a direct 

continuation of that zone towards south, it is expected that even in this part of the Kruje geothermal 

area there are important geothermal resources, at least to an extent similar to those of the TiranaElbasani zone (KAPA Systems and EGEC, 1999).

Geothermal Resources in the Balkans -- Appendix 11
Albania

Notes The geothermal resource is used for medicinal purposes.

Two kilometers east of Peshkopi, thermal springs are situated very close to each other. The thermal 

springs flow out on the Banja River slope, which is composed of flysch deposits, and are linked with 

the disjunctive tectonic zone, in the Ohri-Diber deep fault, peripherically of the Permian-Triassic 

gypsum diapir, that has penetrated the Eocene flysch which surrounds it in a ring-like pattern.

Temperatures vary from a minimum of 12oC at 100 m to 105.8oC at 6000 m. In the central part of the 

Pre-Adriatic depression, where there are many boreholes, the temperature reaches 68oC at 3000 m. 

The thermal springs, which are situated mainly in the regional tectonic fractures, have temperatures 

ranging from 21 to 58oC (KAPA Systems and EGEC, 1999).

Notes The geothermal resource is used for space and district heating, sanitary warm water, swimming pools, 

and balneology at Termia Recreational Center.

Fluid is extracted from two reservoirs at depths of 1800 m and 1600 m. Wellhead temperatures are 

96oC and 85°C with flow rates of 5 kg/s and 3 kg/s (mineralization 2 g/l and 30 g/l), respectively. 

Waste geothermal water has been discharged into

surface water bodies. Separate treatment of waste water is planned.

Bizovac is part of the East-Slavonija geothermal area.

There is an oil-bearing reservoir in a separate lithologic and hydrodynamic unit. The water from Bizgneiss reservoir contains 30 g/l dissolved solids and 1.5 m3/m3 hydrocarbon gas. The water from Bizsandstone reservoir contains 2 g/l dissolved solids and 1.3 m3/m3 hydrocarbon gas. The initial 

reservoir pressure in the gneiss was 30 bars above hydrostatic but rapidly dropped about 30 bars in 

the first year of production. In the sandstone reservoir pressure (initially hydrostatic) declines 

slowly. Scale appeared in the upper 30 m of the production wells and surface facilities. An inhibitor 

is now used (Cubric and Jelic, 1995).

Chronology 1995 - Prefeasibility study conducted by Virkir Orkint Consulting Group Ltd. found project to be 

questionable in terms of financial viability (Jelic et al., 2000).

Notes Carbonate breccia, which form the reservoir rock, is characterised by a porosity of ~7.5. The water 

contains 5 g/l of dissolved solids and 3 m3 of gas (85% CO2, about 15% hydrocarbon and traces of 

H2S). The measured productivity index is 450 m3/bar. In the reservoir evaluation study, an average 

flowrate of 80 kg/s with WHP 3-5 bars and wellhead temperatures of 125-140°C has been predicted.

Reservoir was tested by two exploratory (oil) wells -- Lunj-1 and Kt-1. The distance between the 

wells is 4.1 km; an interference test proved their hydrodynamic connection. The water contains 5 g/l 

dissolved solids and 3 m3/m3 gas (85% CO2, about 15% hydrocarbon and traces of H2S). Scale 

appears at pressures below 10 bars. The reservoir rock is carbonate breccia with an average porosity 

of 7.5%. The average reservior pressure is hydrostatic. The estimated pore volume, by a reservoir 

limit test, is about 10*9 m3 and the reservoir area about 100 km2. In the impermeable rocks, between 

the geothermal reservoir and the earth's surface, the temperature gradient is higher than 0.06oC m-1 

(Cubric and Jelic, 1995).

Chronology 1990 - Reservoir discovered by the exploratory oil well, VC-1 drilled to 4790 m. Log analyses 

showed several permeable zones in the interval 2550-2900 m.

1991 - Special geothermal well, VC-1A, confirmed predicted temperature and a productivity index of 

about 10,000 m3/d bar. Reservoir limit test and an inteference test indicated relatively small pore 

volume of 200-250 10 6 m3; wellhead pressure is 20-25 bars (Cubric and Jelic, 1995).

2005 - 4.4-MWe plant scheduled to become operational using existing well. The prefeasibility study 

on combined electricity and heat production in Velika Ciglena showed that such an energy generating 

plant could operate under economically acceptable conditions (Jelic et al., 2000). 

2015 - Two additional production wells would allow a total installed capacity of 13.07 MWe.

Notes The water from the dolomite reservoir (depth 3000 m) contains 24 g/l dissolved solid and 30 m3/m3 

CO2 with 59 ppm H2S. The predicted production well flowrate is 100 kg/s with wellhead pressure of

Notes The geothermal resource is used for space and district heating, balneology, and sanitary warm water 

at several facilities.

The Zagreb aquifer was discovered by an oil exploratory well. The geothermal water contains 2g/l of 

dissolved solids, 0.1m3/m3 of CO2 and traces of H2S. The reservoir temperature is 55-82°C at depths 

between 500 and 1000m. The very permeable section of the aquifer covers an area of

10km2 in the south-western part of the town in the sub-localities of Blato and Mladost.

At the Blato site, the planned geothermal capacity is 7MWt. In Mladost, there are several large 

buildings for sports activities (indoor and outdoor swimming pools and two other halls), which are 

entirely geothermally heated (6.3MWt), including peak consumption.

“Mladost” Sport Center, located in the south-western part of

the capital Zagreb, uses the water from the Zagreb geothermal

reservoir. The whole complex, including open-air and indoor

swimming pools with all the accompanying facilities, as well

as two sport halls, is entirely heated by geothermal energy,

including peak consumption. Heat is extracted from the water

flowing in a closed system, consisting of a production well,

cascaded heat exchangers, injection pumps and an injection

well. Pressure resulting from the density difference of water

with different temperatures is used to establish thermosiphon

injection. Consequently, the injection system can operate

without the support of the injection pumps for more than 7500

hours/year; installed capacity is 14.54 MWt (Jelic et al., 2000)

The University Hospital uses the geothermal resource for space heating and sanitary warm water; 

Geothermal Resources in the Balkans -- Appendix 35

installed capacity is 6.90 MWt

INA Consulting uses the geothermal resource for space and district heating; installed capacity is 0.58 

MWt.

The Lucko Factory uses the geothermal resource for space heating and sanitary warm water.

The Sveta Helena and Sveta Jana Spas use geothermal water for swimming pools.

A total of 17 exploratory and development wells have been drilled. Biogenic limestone of the 

Miocene age underlies the entire town and its suburbs (200 km2), but its permeability in the major 

part is not high enough for reasonable geothermal development. The geothermal water contains 2 g/l 

disolved solids, 0.1 m3/m3 CO2, and trace H2S. The most permeable part of the aquifer covers an 

area of 10 km2 in Blato and Mladost, the southwest suburbs of Zagreb. Initial reservoir pressure was 

106 bars at 1000 m (Cubric and Jelic, 1995).

Chronology Roman times - A natural hot spring with 30-35 l/s of 72oC water was used for bathing.

1963 - Agricultural company "Strumica" built the first commercial glasshouse for vegetable 

production in Macedonia. The 3.2-ha greenhouse complex was built about 200 m from the Bansko 

spring, becoming the first geothermally heated greenhouse in the world.

1985 - The Hotel "Car Samuil" was built near the spring. It uses geothermal water for heating, 

sanitary water, and balneology.

1988 -Thermal well drilled to 600 m; encountered a maximum temperature of 60oC; flowing enthalpy 

of 251 kJ/kg (Dimitrov et al., 1990). 

1994 - The geothermal system broke down due to political changes and the resulting undefined legal 

property issue. A "war for water" began as small farmers (owners of the complex of small soft 

plastics-covered greenhouses) tried to obtain the right to exploit the geothermal water, using the water 

in an improper way and destroying the previously accommodated water distribution system 

(Popovska-Vasilevska and Popovski, 2000).

The geothermal heat source and the common elements of the integrated project (e.g., well, central 

station, distribution pipes, etc.) belong to no one; no one is responsible for their proper maintenance 

and exploitation. The well is over-pumped continuously during the winter months. 

1999 - Feasibility study called for reorganizing the integrated Bansko project. 

2000 - Legislation was introduced to define ownership rights.

Geothermal Resources in the Balkans -- Appendix 40
FYR of Macedonia

Notes The geothermal resource is used for greenhouse and soil heating, space and district heating, sanitary 

warm water, and bathing and swimming in the Bansko integrated geothermal project. 

The water is low corrosive and is used directly in the steel-pipe heating installation.

Bankso was the first commercial block of greenhouses to be heated by geothermal energy in the 

world. The greenhouse complex is the only one in Macedonia that has constantly been profitable, 

even during the most difficult economic times (Popovski and Lund, eds., Popovski, 1999). 

Seven users utilize the resource: the ZIK Strumica Greenhouse, the Hotel "Car Samuil," the Spiro 

Zakov Hotel, the ZIK Strumica Hotel, private farmers' greenhouses, an open air swimming pool, and 

rest houses for children and retirees. The maximum geothermal heat power is 7.804 kW; the required 

flow rate is 70.09 l/s.

The greenhouse installations are connected improperly and disturb the proper use of the total system.

Bankso has temperatures of 68-73oC, flow rates of 6-55 l/s, and a heat power of 20.5 MWt (Popovski 

and Popovska-Vasilevska, 1999). The predicted temperature is 115-120oC (Popovski and Lund, eds., 

Gorgieva, 1999).

The Bankso project has never been finished. The Hotel "Car Samuil" is working more or less 

according to the design capacity; the greenhouse installations are obsolete and incorrect and hinder 

the overall system's proper use. Two additional hotels are not yet connected to the system (Popovski 

and Popovska-Vasilevska, 1999). 

If taking the temperature of effluent water of 25oC as economically feasible for the existing 

composition of users, the maximum geothermal heat power on disposal is 10.3 MWt.

According to the results of the feasibility studies made (Popovski et al., 1989), (Popovski, 1992) and 

(Popovski, Lund, 1999), it is technically possible and economically feasible to connect the heat users 

Geothermal Resources in the Balkans -- Appendix 41
FYR of Macedonia

by introducing a heat accumulator and activation of the already installed light oil boilers (in the Hotel 

"Car Samuil") for covering the peak loadings during the cold winter mornings. In that way, the 

system shall be composed of heat users with a total design heat power of 7.8 MWt. If market 

conditions for out-of-season vegetables improve, it shall be possible to reach even 9 MWt (by 

connecting a larger number of small greenhouses, using the lower part of the temperature difference 

on disposal), which is very near to the maximal heat power on disposal.

The main characteristics of the Bansko system are: the recharge and discharge zone occur in the 

same lithological formation-granites; there are springs and boreholes with different temperatures 

within small distances; maximum measured temperature is 73oC; the predicted maximum temperature 

is 120oC (Gorgieva, 1989); the reservoir in the granites lies under thick Tertiary sediments. The 

Bansko geothermal system has not been examined in detail apart from the drilling of several 

boreholes with depths of 100-600 m (Gorgieva et al., 2000).

Flow rate is 55 kg/s; inlet temperature is 70oC; outlet temperature is 35oC; installed capacity is 8.05 

MWt; annual utilization is 83.26 TJ/yr (Dimitrov et al., 2000).

Chronology 1983 - Greenhouses (22.5 ha) using geothermal energy began operating.

2001 - The greenhouse company is interested in finding a foreign partner to help develop the 

geothermal field. They would like to drill deep exploration and production wells (1500-2000 m).

Notes The geothermal resource is used for the Negorska Banja Spa and the Smokvica agricultural project. 

The hydrogeothermal system in the Gevgelia Valley is emptied at the surface through a natural spring 

near the village of Gornitchet, numerous natural springs and exploratory boreholes in Negorska 

Banja, and seven exploratory wells in Smokvica.

The Gevgelia Valley is located within the subduction Vardar zone which runs from Turkey through 

Greece to the Hungarian (Pannonian) basin. There are two geothermal fields in the Gevgelia valley: 

Negorska Banja and Smokvica. The discharge zone in both geothermal fields is in fault zones 

bounded by Jurassic diabases and spilites. Although these two fields are separated by several km 

there is no hydraulic connection between them, despite intensive pumping of thermal waters. The 

maximum temperature is 54oC, and the predicted reservoir temperature is 75-100oC. The geothermal 

system in the Gevgelia valley has been well studied by 15 boreholes with depths between 100-800m 

(Gorgieva et al., 2000).

used for heating 6 ha of glasshouses. Installed capacity is 4.92 MWt; annual utilization is 50.99 TJ/yr 

(Dimitrov et al., 2000).

The Istibanja project was never completed. Due to improper installation, operation is intermittent and 

the connections are rusted (Popovski and Popovska-Vasilevska, 1999). The geothermal system is 

now nearly abandoned.

Istibanja has temperatures of 56.6-67oC, flow rates of 4.2-12 l/s, and a heat power of 5.3 MWt 

(Popovski and Popovska-Vasilevska, 1999). The predicted temperature is 100oC (Popovski and 

Lund, eds., Gorgieva, 1999).

After electrical resistivity measurements, 12 shallow wells (up to 30 m deep) were drilled to locate 

the upflow zone. The water temperature in all 12 is 30-40oC. In addition, a 180 m-deep borehole 

yielded 2 l/s of 60oC thermal water, and another at 190 m yielded 6 l/s at 60oC. The latest production 

wells have been drilled to 200-350 m and resulted in a total flow of about 60 l/s at 60oC (Popovska et 

al., 1995).

The Istibanja reservoir is of gneisses and granites (Popovski and Lund, eds., Gorgieva, 1999).

Notes The geothermal resource is used for balneology at the Kezovica Spa.

The geothermal system is manifested at the surface through the natural spring Lzi in Novo Selo, on 

the right bank of the Bregalnica River. Its temperature in 1977 was 54oC, but it now has a 

temperature of 30oC and a very small flow. The spa uses water from two shallow wells with a flow 

of 4.5 l/s and a temperature of 63oC (Popovski and Lund, eds., Gorgieva, 1999).

Kezovica has a temperature of 57oC, a flow rate of 7 l/s, and a heat power of 1.3 MWt (Popovski and 

Popovska-Vasilevska, 1999). The predicted temperature is 100-115oC (Popovski and Lund, eds.,

Chronology 1980 - Borehole EBMP-1 drilled to 328 m; maximum capacity of 150 l/s (100 l/s for continual use) 

offered possibilities to resolve the bad energy situation of the neighboring 12 ha-greenhouse complex 

“Kotchansko pole." 

1982 - 18 ha of geothermally-heated glasshouses began operating. Non-corrosive water permitted the 

direct use of brine in the heating system. 

Agricultural combine “Mosha Pijade” decided to build a new greenhouse complex of 6 ha (15 MWt 

design heat power). The initial artesian pressure of 6.5 bars dropped to 0 bars during the first year of 

joint exploitation. As a result, the well in Banja, fed by the same geothermal field, ran dry and the 

existing balneological use was stopped.

A contract was later signed which regulated the division of available water flow.

1983 - A rice drying plant of 1.36 MWt was connected to the geothermal system. 

New borehole yielded up to 400-600 l/s, far above the real renewal capacity of the reservoir. 

1990s - Due to the economic blockade of the early 1990s and the loss of export markets in the former 

Yugoslavia, the export markets for vegetables, paper, and rice were lost. The vehicle parts

production industry stopped operating. Rice, formerly exported to Yugoslavia, lost that market and 

could not compete with cheaper Asian rice on the world market; the rice drying facility ceased 

operations. 

1994 - The integrated system consisted of different heat users of about 60 MWt design heat power.

A concession to exploit the Kochani geothermal field was given to the publically-owned water 

management firm, Vodovod, which has no interest in picking up additional "side" work (Popovski 

and Popovska-Vasilevska, 2000).

Notes The geothermal resource is used for greenhouses, agricultural drying, industrial processing, and 

district heating.

The integrated Kochani geothermal system is the largest in Macedonia and among the largest in 

Europe. It includes a heating system for 180,000 m2 of greenhouses, a rice drying facility, a paper 

production facility, a vehicle parts production factory, and six buildings (Popovska et al., 1995). The 

system's maximum heat power is 70-80 MWt.

The district heating scheme (designed 10-12 years ago) and the greenhouses (designed 15 years ago) 

are not in optimal working condition due to weak maintenance. The rice drying unit is out of 

working condition (Popovski and Popovska-Vasilevska, 1999). 

The 78oC water is too hot for the known types of submersible pumps. Spare pumps and reserve wells 

are necessary for secure exploitation of the resource. In order to neutralize the aggressive effects of 

used thermal water, a treatment plant has been designed. (Dimitrov et al., 2000).

The Kochani geothermal system is the best-investigated system in Macedonia. There are more than 

25 boreholes and wells with depths of 100-1170 m (Gorgieva et al., 2000).

The geothermal system was developed without a defined development strategy. In the future, it is 

necessary to collect all the effluent water of the system and to reinject it back into the reservoir. More 

Geothermal Resources in the Balkans -- Appendix 50
FYR of Macedonia

"reserve" wells should be drilled. A complete reconstruction of the heating system and addition of 

new low-temperature users (e.g., aquaculture, soil heating, etc.) is necessary.

The task for the near future is to improve the present annual heat loading factor of about 0.35 to 0.60 

(based on the maximum allowed continuous geothermal water flow of 170 l/s) with a better heat 

consumption distribution over the year. That should decrease the price of the used heat unit for about 

60% and prevent winter over-pumpings and sudden water level decreases.

The Kochani Valley has three primary geothermal localities: Podlog, Banja, and Istibanja (or 

Vinica). The valley forms the border between the Vardarian zone and the Serbo-Macedonian mass. 

The Kochani hydrogeothermal system is drained through the exploitation wells and boreholes in three 

fields: the village Banja, the village Dolni Podlog, and the village Istibanja. Banja and Podlog are in 

direct hydraulic connection (Popovski and Lund, eds., Gorgieva, 1999). Two major faults, both 

seismically active, run east-west.

The basic characteristics of the main geothermal spring are:

- constant discharge temperature of 78°C

- high but variable discharge capacity of 100-250 l/s

- high but variable water pressure at the discharge point

with a mean value of 0.65 MPa

- non-aggressive water, with low levels of total dissolved

solids and a pH = 6.8

- carbonic hardness of 23.9°C (425 mg/l CaCO3 equivalent)

- CO2 is in balance with free CO2 and the water is potable.

- The well is sited in an aquifer with thermally advantageous

hydro-geological parameters but with limited dimensions.

- The production well reaches only the upper part of the

aquifer and its thickness is still not established.

- The aquifer is bounded horizontally by several aquifers

of lower transmissivity, and there are hydraulic boundaries

primary reservoir in Precambrian and Paleozoic marbles covered by thick volcanogenic sedimentary 

rocks; presence of magmatic intrusions near the surface; borehole temperature up to 42oC; travertine 

deposits over young andesite and breccia (Gorgieva et al., 2000).

The Povisica-Kratovo hydrogeothermal system is one of the largest in Macedonia, according to 

volume. It lies at the border of the Vardarian zone and the Serbo-Macedonian mass. The system is 

drained through two exploratory boreholes in the Povisica River valley near the village of Zdravevci, 

and three boreholes in the Dobrevo mine (Popovski and Lund, eds., Gorgieva, 1999).

Chronology 1983 - Several shallow boreholes, between 20 and 130 m deep, were drilled.

1984 to 1985 - Two boreholes of 600 m each were drilled, resulting in a total thermal water flow by 

pumping of 80l/s at 51°C.

1986 - Borehole drilled to 300 m intersected a permeable fault at 250 m with a water temperature of 

62oC; used Head-On Resistivity profiling for the first time in the country.

1988 - Thermal pumped well drilled to 400 m; encountered a maximum temperature of 60oC; flowing 

enthalpy of 251 kJ/kg (Dimitrov et al., 1990).

Notes The geothermal resource is used for space and district heating, bathing, and swimming. 

The Negorska Banja has a very primitive, "self-made" central heating system which is presently not 

operating (Popovski and Popovska-Vasilevska, 1999). 

Negorska Banja has temperatures of 32-53.2oC, flow rates of 3-40 l/s, and a heat power of 13.1 MWt 

(Popovski and Popovska-Vasilevska, 1999). The predicted temperature is 75-100oC (Popovski and 

Lund, eds., Gorgieva, 1999).

Flow rate is 80 kg/s; inlet temperature is 51oC; outlet temperature is 46oC; installed capacity is 1.67 

MWt; annual utilization is 8.67 TJ/yr (Dimitrov et al., 2000).

Negorska Banja is characterized by steeply dipping diabases of Tertiary age and by numerous dykes 

and granite intrusions. The production horizon seems to be associated with spilites at a very shallow 

depth of 100-150m, and at the intersection of faults.

There are two geothermal fields in the Gevgelia valley: Negorska Banja and Smokvica. The 

discharge zone in both geothermal fields is in fault zones bounded by Jurassic diabases and spilites. 

Although these two fields are separated by several kilometers, there is no hydraulic connection 

between them, despite intensive pumping of thermal waters. The maximum temperature is 54oC, and

the predicted reservoir temperature is 75-100oC. The geothermal system in the Gevgelia valley has 

been well studied by 15 boreholes with depths between 100-800 m (Gorgieva et al., 2000).

1980 - A deeper well was drilled near EBMP-1. At 307 m, an aquifer was intersected, yielding over 

150l/s free flowing water at 79°C. 

1980 to 1986 - Eighteen (18) exploratory and production wells were drilled in the area, resulting in a 

total possible yield of 600 l/s and water temperatures of 57-79°C.

1988 -Two production artesian wells drilled to 350 m; encountered maximum temperatures of 68oC 

and 60oC; flowing enthalpies of 285 kJ/kg and 251 kJ/kg, respectively (Dimitrov et al., 1990).

Notes The geothermal resource is used for industrial process heat, greenhouse and soil heating, space and 

district heating, bathing and swimming, and agricultural drying.

Podlog has temperatures of 22.4-78oC, flow rates of 0.5-150 l/s, and a heat power of 161.6 MWt. 

Designed in the early 1980s, the system is not optimized for the intensive growing of vegetables and 

flowers but, due to good maintenance and proper exploitation, the system works well (Popovski and 

Popovska-Vasilevska, 1999).

Flow rate is 300-450 kg/s; inlet temperature is 79oC; outlet temperature is 38oC; installed capacity is 

51-77.20 MWt; annual utilization is 223.00 TJ/yr (Dimitrov et al., 2000). The predicted temperature

been observed during exploitation, probably due to the infiltration of colder water from surrounding 

rocks or non-sealed, non-cemented wells.

There are two geothermal fields in the Gevgelia valley: Negorska Banja spa and Smokvica. The 

discharge zone in both geothermal fields is in fault zones bounded by Jurassic diabases and spilites. 

Although these two fields are separated by several kilometers, there is no hydraulic connection 

between them, despite intensive pumping of thermal waters. The maximum temperature is 54oC, and 

the predicted reservoir temperature is 75-100oC. The geothermal system in the Gevgelia valley has 

been well studied by 15 boreholes with depths between 100-800 m (Gorgieva et al., 2000).

Toplec has a temperature of 25oC, a flow rate of 2 l/s, and a heat power of 0.1 MWt (Popovski and 

Popovska-Vasilevska, 1999).

This system is characterized by relatively low temperatures, up to 28oC, and low predicted reservoir 

temperatures because of lack of water-rock equilibrium and mixing of hot and cold water. It has not 

been studied in detail (Gorgieva et al., 2000).

Two exploratory boreholes were drilled in the vicinity of the natural spring; the water is used for 

irrigation. The system is also drained with the exploitation well "Deribas" near the town of Star 

Dojran, and with the natural spring near Mrdaja (Popovski and Lund, eds., Gorgieva, 1999).

The Toplec hydrogeothermal system is drained naturally by the thermal spring in Toplec which 

gradually lowers the flow and temperature of the water.

With a surface area of 7000 m2, Terme Catez is the largest geothermally heated pool complex in 

Slovenia. The resource at Terme Catez has a maximum flow rate of 80 kg/s, a capacity of 10.04 

MWt, produces 158.3 TJ/yr, and has a capacity factor of 5%.

The Agraria Catez resource has a maximum flow rate of 80 kg/s, a capacity of 8.70 MWt, produces 

137.2 TJ/yr, and has a capacity factor of 5% (Kralj and Rajver, 2000).

The maximum flow rate at utilization is 80 kg/s for both the pool and the greenhouse complex. They 

do not interfere much with each other because Terme Catez is most active during the summer and the 

Agraria is most active during the winter.

More than 20 wells have been drilled in Catez. The deepest borehole is 570 m, the maximum yield 

from a single well is 50 l/s, the maximum temperature is 64oC.

Chronology 1987 and 1988 - Two exploitation wells (Sob-1 and Sob-2) were drilled, to 870 m and 887 m, 

respectively. The wells penetrated Upper Pliocene intergranular acquifer, Termal I, and some 

underlying Lower Pliocene acquifers. Water levels in the wells constantly decreased, as did total 

dissolved solids (Kralj and Kralj, 2000).

Notes The geothermal resource is used for space and district heating, bathing, and swimming. Threehundred dwellings are heated through heat exchangers, especially from October to April.

The geothermal resource has a maximum flow rate of 25 kg/s, a capacity of 1.78 MWt, produces 24.7 

TJ/yr, and has a capacity factor of 44% (Kralj and Rajver, 2000).

The town of Murska Sobota (pop. 15,000) is located in the Mura basin which is part of the 

widespread system of the Pannonian basins. The most important thermal acquifer in the region is 

Termal I which formed in Upper Pliocene by the stacking of braided river deposits. It consists of up 

to a 100-meters thick sedimentary sequence of interbedded sands, silts, and clays, in which the 

thickness of beds with good permeability varies from 20-50 meters (Kralj and Kralj, 2000).

Intensive exploitation of Sob-1 and Sob-2 is reflected in a very decreased yield of thermal water, 

changing hydrodynamic pressures in Termal I near both wells, and the changing chemical 

composition of the water. Reinjection is necessary (Kralj and Kralj, 2000).

Chronology 1981 - First geothermal well BD-1 drilled to 400 m; yielded 50oC water with a flow rate of 15 kg/s.

1982 - Hydrothermal system discovered when a high conductive geothermal anomaly was detected in 

deposits at Dublje, central Macva, by borehole DB-1.

Since 1987 - 11 boreholes have been drilled in Semberia and Macva. Well BZ-1 is the deepest, with 

a depth of 1500 m. The reservoir depth is 400-600 m; water temperature is 80oC.

Notes Completed studies indicate that thermal water exploitation in Macva can provide district heating 

systems for Bogatic, Sabac, Sremska Mitrovica, and Loznica, with a population of 150,000.

Macva is one of the best agricultural regions in Serbia, and Yugoslavia, which makes the geothermal 

resources in its convective hydrogeothermal system extremely important for food production, heating 

of homes and green-houses. The chemical composition of the thermal waters is suitable for direct use; 

for example, calcite scaling in BB-1 will be 900 g/day at a pumping rate of 37 kg/s and temperature 

Temperature (oC) to 110

of 75oC (Papic, 1992).

A design was prepared for 25 hectares of green houses for production of vegetables, fruits, and 

flowers. The project cost estimate is about US$43 million. However, the project ctivities have been 

discontinued due to the economic blockade of Serbia and Yugoslavia.

On the southern part of the Pannonian Basin, Macva is located in the area with the greatest 

geothermal anomaly in Serbia (Bodri, 1982). 

A conductive geothermal anomaly, the highest in the Pannonian Basin (thermal water of 75oC found 

in the borehole BB-1 at the depth of 412 m), was detected above the reservoir in central Macva 

(Milivojevic and Peric, 1987). This makes Macva the Yugoslavian, and Serbian, "Red Spot", as the

Pannonian Basin is for Europe (Horvath et al., 1979).

Geothermal anomalies in Neogene sediments and previous hydrogeothermal investigations indicate 

thermal water-bearing

Triassic limestone beneath Neogene sediments throughout the whole Macva region. The highest 

measured temperature is 78oC at a depth of 610 m in Triassic limestone. The highest temperature 

expected in the aquifer on the basis of hydrochemical geothermometers, is about 100-110oC. Natural 

conditions in Macva are favorable for intensive exploitation of geothermal energy. Based on the local 

geology, hydrogeological and hydrothermal characteristics, the calculated thermal power potential of 

the Macva region is approximately 1500 kg/s of 75oC water or 150 MWt, based on a reservoir surface 

area of 800 km2 (Martinovic and Milivojevic, 2000).

The full extent of the geothermal anomaly has not been determined.
