In this paper, a description is given of the national policy, legal framework, official monitoring and accumulation of geothermal energy statistics in Iceland in a global context. The legal framework and amendments to the energy legal framework since 2010 will be reviewed. In particular the effect of Act for the Master Plan for the Utilization and Protection of Energy Resources no. 48/2011 which sets up the legal framework for the Master Plan which has been in preparation since 1999, where geothermal and hydro resources are categorized to be exploited, protected or further researched. It is the policy of the Government of Iceland to increase the utilization of energy resources and hence governmental support was increased for new geothermal based heat utilities by 50% even though 9 out of 10 households are heated with geothermal energy. The Icelandic National Renewable Energy Action Plan was published in year 2012 in accordance with Directive 2009/28/EC which outlines the strategy for 2020 and goals of geothermal utilization. In accordance with the plan, electricity generation from geothermal sources is estimated to increase by 12% from 5.2 TWh in year 2014 to 5.8 TWh in year 2020 and geothermal heat use from 28.1 PJ in year 2014 to 34 PJ in year 2020. Geothermal energy plays an important role in providing the nation with clean and reliable energy and is fundamental to the Icelandic economy as well as Icelandic welfare and independence. Effective policy making and official monitoring of geothermal development for sustaining a renewable energy society in Iceland is crucial for sustaining a long-term lifespan of the resource. Population growth is expected of 36% until 2050 and geothermal utilization is estimated to increase by over 70% until 2050 to almost 50 PJ.
During the 20th century Iceland has emerged from being a nation dependent upon imported oil and coal, to a country where practically all stationary energy, and 86% of primary energy, is derived from domestic renewable sources with near carbon-free electricity production in year 2014. This is the result of an effective policy in making renewable energy a long-term priority in Iceland. Nowhere else does geothermal energy play a greater role in providing a nation’s energy supply. In Figure 1 an overview is given of the main production wells in Iceland operated by main activity producers for electricity generation and heat production. On the image are excluded auto-producers which are well over 100 in Iceland although only 14% of the final use is from them but 86% (24.1 PJ) from main activity producers.

Already in the 1940s, the State Electricity Authority promoted geothermal development and carried out a regional survey of geothermal areas suitable for space heating and explored promising fields with exploratory drilling. The capital Reykjavik obtained by law a monopoly to operate a geothermal heating service in the town and took the initiative in production drilling and establishment of the first large geothermal district heating system. The State guaranteed loans for the construction of the system. In 1950 about 25% of families in the country enjoyed geothermal heating services, 40% used coal and 20% oil for heating. The low cost geothermal heating was attractive and intensified the flux of people from rural areas to the capital. To balance that the Parliament approved an Act in 1953 on geothermal heating services in communities outside Reykjavik which permitted the State to guarantee loans up to 80% of the total drilling and construction cost of heating services. Further, to encourage the development, the State established a Geothermal Fund in 1961. The fund gave grants for reconnaissance and exploratory drilling carried out by the Geothermal Department of the State Electricity Authority and offered loans to communities and farmers for exploratory and appraisal drilling covering up to 60% of the drilling cost. If the drilling was successful the loans were to be paid back at the highest allowed interest rate within 5 years of exploitation commencement. If the drilling failed to yield exploitable hot water the loan was converted to a grant and not paid back. In this way the fund encouraged exploration and shared the risk. Within the next 10 years many villages used this support and succeeded in finding geothermal water. In 1967 the fund was merged with the Electricity Fund and named the Energy Fund. The Electricity Fund had since the 1940s supported electrification and transmission in rural areas. Over 350 geothermal loans have been issued since the beginning that has led to the wide spread use of geothermal across Iceland.
When the oil crisis struck in the early 1970s, fuelled by the Arab-Israeli War, the world market price for crude oil rose by 70%. At about the same time, close to 90,000 people enjoyed geothermal heating in Iceland, about 43% of the nation. Heat from oil served over 50% of the population, the remainder using electricity. In order to reduce the effect of rising oil prices, Iceland began subsidising those who used oil for space heating. The oil crises in 1973 and 1979 (Iranian Revolution) caused Iceland to change its policy, reducing oil use and turning to domestic energy resources; hydropower and geothermal heat. This policy meant exploring for new geothermal resources, and building distribution networks. It also meant constructing transmission pipelines (commonly 10‒20 km) from geothermal fields to towns, villages and individual farms. This involved converting household heating systems from electricity or oil to geothermal heat. But despite the reduction in the use of oil for space heating from 53% to 7% from 1970 to 1982, the share of oil still remained about 50% to 60% of the total heating cost due to rising oil prices. Today about nine out of ten households are heated with geothermal. In Figure 2 areas of various users are shown that either are auto-producers or buy heat from main activity producers. Total use of geothermal energy amounted to 28.1 PJ in year 2014 as can be seen in Figure 3. From an economical perspective, the present value of the estimated savings of house heating with geothermal instead of oil between 1914 and 2013, using 2% real interest rate over the cost price index, is estimated at 2,500 billion ISK (132 ISK/US$) (see Figure 4). In 2014 the estimated savings of that year amounted to about 5.5% of the GDP of Iceland or 2,300 US$ per capita only for 2014. Beside the economical impact of high energy security and avoided cost of importing energy to the country, there are also environmental benefits for reducing greenhouse gas emission by using geothermal energy compared to conventional fossil fuel based technologies. In 2014 geothermal utilization reduced the anthropogenic release of CO2 by 5.0 million tonnes for geothermal based electricity generation and 3.4 million tonnes for geothermal based heat use compared to coal. This has also considerably improved air quality in populated areas over the decades since the time Icelanders used to heat their houses with coal and later oil.
Figure 2: Satellite image of Iceland in summer time showing where geothermal is used for various uses like swimming, fish farming, industrial processes and heating greenhouses in year 2014.
Geothermal utilization amounted to 28.1 PJ in 2014 as shown in Figure 3 using both IGA and IEA final use categories. Residential use amounted to 13.3 PJ, commercial services to 0.7 PJ, fisheries to 2.5 PJ, industry 0.9 PJ and services 10.7 PJ using IEA categories. Space heating amounted to 20.0 PJ, swimming and bathing 2.0 PJ, snow melting 2.0 PJ, fish farming 2.5 PJ, industrial use 0.9 PJ and greenhouses 0.7 PJ using IGA categories. Detailed monitoring of geothermal utilization has been set up in Iceland by Orkustofnun with data from over 53 geothermal based heat utilities (where geothermal energy production is the main business activity) and over 100 auto-producers (where geothermal energy is produced mainly for own use in support of some business) of geothermal energy using a web portal for authentication. The data is accumulated and analysed annually by Orkustofnun with 19 categories of utilization in order to be able to fully disseminate information to the public in accordance with the legal role of the institution and international requirements.

The main international agencies and offices have already joined forces in collecting energy statistics with annual questionnaires with historical revisions. Two of those questionnaires collect geothermal energy statistics, Annual Questionnaire on Renewables and Annual Questionnaire on Electricity and Heat in addition to Mini-Questionnaires. Those international agencies that collectively and consistently gather this data are; the Energy Statistics Division of the International Energy Agency (IEA), the Organisation for Economic Co-operation and Development (OECD), the Statistical Division of the United Nations Economic Division for Europe (UNECE), the Statistical Office of the European Communities (EUROSTAT) for the Commission of the European Communities (EC) and finally the Statistics Division of the United Nations (UN). It is the legal responsibility of Orkustofnun to gather energy statistics for which the institution can enforce by means of fines on companies that are obliged to submit the data. Orkustofnun is gathers and maintains an energy statistics database that is coherent and meets the requirements of the relevant regulation which in this case is the regulation (EC) No. 1099/2008 on energy statistics. Therefore Orkustofnun is obliged to follow the framework set out in the regulation.Within the geothermal industry Orkustofnun participates in several associations and partnerships and collaborates with many others like the Implementation Agreement within the IEA (IEA Geothermal), International Geothermal Association (IGA), European Geothermal Energy Council (EGEC), Geothermal ERA NET, International Partnership for Geothermal Technologies (IPGT) to name a few. As part of the role of these organizations, data collection on geothermal energy statistics is often the focus of the work, in particular of the IEA Geothermal, EGEC and IGA. However the industry statistics between these multinational associations are inconsistent, and also differ from the official statistics. The fact is that the industry statistics are quite fragmented although consistent within the respective association. With time, databases have been developed and special annual questionnaires have been established within each association which make up what is here referred to as industry statistics as previously noted. In some cases the data collection is similar but often there are important differences that result in the data not being interoperable across associations and when numbers are compared from one to the other, drastic differences can be found which can be difficult to resolve. Orkustofnun is one of few institutions that in the past has both accumulated, interpreted and disseminated both the official statistics and the industry statistics on geothermal data and hence is able to have a broad overview of the various data being collected by different organisations as shown in Figure 3. Taking into account that the aim of international collaboration is to reduce fragmentation, it is the position of Orkustofnun that this is one of the key issues that need to be resolved. Therefore it is ideal for Orkustofnun to share its knowledge of data reporting to the geothermal community and with time this fragmentation will hopefully be reduced. Through the Geothermal ERA NET a special Joint Activity called GeoStat has been proposed for reducing this fragmentation and increase consistency. For further review see report by Ketilsson et al. (2015).
Figure 4: Avoided cost of using geothermal energy instead of oil. The lower columns show actual total utility revenues for hot water but the higher columns the estimated cost with oil, adjusted to a price index (1 US$ = 132 ISK).
The information Orkustofnun disseminates is based on the accounting system of the heat utilities after extensive review and collaboration over recent years which still is ongoing to ensure the reliability of the information. For the first time categorization of space heating for residential and commercial and public services is possible. Verification of the information is through comparison of data from Registers Iceland and Iceland Met Office. That being said, the focus of this paper is not to give a detailed account of statistics in Iceland. The point is to examine Icelandic policy in respect of geothermal energy, both research and utilisation, and at the same time observe how official monitoring of both geothermal research and utilisation manifests itself in Icelandic legislation and amendments from a previous review in year 2010 (Ketilsson et al., 2010).
2.1 National Renewable Energy Action Plan for 2020
The Icelandic National Renewable Energy Action Plan (NREAP) was published in year 2012 in accordance with Directive 2009/28/EC which outlines the strategy for 2020 and goals of geothermal utilization amongst other renewable energy sources. Promotion of the use of energy from renewable sources was further stipulated by changing law no. 30/2008 for promotion of electricity generation with renewable resources taking into consideration Directive 2009/28/EC. For 2020 the total use of geothermal energy for heating is estimated to increase by 20% until year 2020 from 28.1 PJ in year 2014 to 34 PJ in year 2020. Electricity generation from geothermal power plants is expected to increase by 12% from 5.24 TWh in year 2014 to 5.8 TWh in year 2020 according to the NREAP which corresponds to about 80 MW installed electrical capacity. This excludes possible investments in the power intensive industry which is subject to great uncertainty but corresponds to general increase in electricity demand in the country for other sectors. The predicted overall share of renewable energy of final energy use in Iceland of 72% as a binding target has already been achieved in year 2014.The Icelandic Government has expressed a strong will and supported various research and demonstration programs for the transition from hydrocarbon fuels, e.g. methane collected from waste-deposits, hydrogen generation and recycled carbons. In the NREAP for 2020 a goal of 10% share of renewables is targeted. Currently oil is still needed for 12% of the primary energy demand in the country, about half to operate the fishing fleet and the other half mainly for motor vehicles. All electricity in Iceland is produced from renewable energy sources and 18.1 TWh/a are generated in year 2014. One of the possibilities of transition from hydrocarbon fuels is thus electricity as fuel. It is estimated that 0.6 TWh are required to drive private motor vehicles in Iceland (200,000 in total) with 200 Wh/km consumption. The capacity needed is thus about 170 MW assuming 15,000 km/yr per vehicle. This means that all use of electricity in transport, in Iceland, can be fossil free from well to wheel. Carbon dioxide capturing from geothermal power plants can as well be a source for alternative fuel by converting it to methanol, e.g. Carbon Recycling Ltd. is running a pilot plant at Svartsengi power plant for this purpose with promising results. Up to this time, Iceland has been an island not only geographically but also economically to a greater extent than many of its neighbours in Europe (Björnsson, 1995). In recent years another possibility, besides energy intensive industry in Iceland, of increased utilisation, of the country’s energy resources has been considered with growing seriousness, viz. export of electricity via HVDC submarine cables. The feasibility of interconnecting the country to mainland Europe is under assessment. Not only is there a need for a cable but also for further interconnection of the transmission system on land. Hence the issue is complex and needs thorough investigation.

2.2 Geothermal Energy Forecast 2014-2050
The Geothermal Working Group, under the Icelandic Energy Forecast Committee, has regularly developed a multi decade forecast for geothermal utilization in Iceland based on assumptions concerning the development of Icelandic society. The base assumptions are stipulated by the Energy Forecast Committee and are common to all energy forecasts for Iceland. Orkustofnun compiles the energy statistics data, which in turn is important for all studies on future geothermal utilization that are used for the forecast. A new geothermal forecast for the period 2014‒2050 is now being developed. It will describe the assumptions used and the predicted effect geothermal utilization will have on the renewable energy sector in Iceland. Statistics Iceland predict a population growth of 36% until 2050 so geothermal utilization, e.g. residential and commercial services, is expected to increase considerably over the next decades. The energy forecast committee has predicted the total cubic meters of heated buildings to increase by 50% until 2050 from the current value of 60 million cubic meters to close to 90 million cubic meters. In total geothermal use is predicted to increase from 28.1 PJ in year 2014 to 48.6 PJ in year 2050 (see Figure 5). Fish farming is expected to increase considerably relative to other sectors.
2.2 Market Development and Stimulation
The government has encouraged exploration for geothermal resources, as well as research into the various ways geothermal energy can be utilised. As stated earlier this work began in the 1940’s at The State Electricity Authority, and was later for decades, in the hands of its successor, Orkustofnun, established in 1967. The aim has been to acquire general knowledge about geothermal resources and make the utilization of this resource profitable for the national economy. This work has led to great achievements, especially in finding alternative resources for heating homes. Since the electricity market was liberalized with adaption to EC Directive in year 2003 Orkustofnun only contracts research for exploration of domestic resources. According to a new Energy Act in 2003, the Energy Fund is now under Orkustofnun.Geothermal energy is today competitive with hydro in Iceland and is not subsidised; providing reliable base load, small surface footprint, green energy and favourable prices; 14.2 ISK/kWh + VAT for 3.5 MWh/a public consumption (of which 9.1 ISK/kWh is for distribution and transmission) but can get considerably lower for the power intensive industry due to a high load factor and no distribution cost. Transmission and distribution costs are high in Iceland due to low population density. See total generation per month in Figure 6 from geothermal power plants in Iceland showing how stable the generation is over the year. For cost of residential heating see Figure 7. In recent years geothermal has become cost-competitive for electricity which was not the case a few decades ago (Bjornsson, 1995) when geothermal was not competitive with hydro on a major scale.Space heating of residential buildings is subsidized by the state as shown on Figure 6 for those areas where geothermal based district heating systems are not reachable. The lump sum of this state subsidization for 8 years has been available to support home owners to transform to renewable heating (Act No. 78/2002). This has recently been increased by 50% to be equivalent of 12 years lump sum. In addition if the project receives other grants it will not effect in any way this lump sum payment. This has stimulated new geothermal based district heating systems to be installed like in the town of Skagastrond, operated by RARIK in year 2013.New and effective exploration techniques have been developed to discover geothermal resources. This has led to the development of geothermal heating services in regions that were not thought to enjoy suitable geothermal resources. Iceland’s geothermal industry is now sufficiently developed for the government to play a more limited role than before. Successful power companies now take the lead in the exploration for geothermal resources; either geothermal fields that are already being utilized, or discovering new fields.
Figure 6: Electricity generation by geothermal power plants per month for the past three years.
The Government supports the Iceland Deep Drilling Project (IDDP) with 342 million ISK. If successful this project could start a new era in geothermal development. The main purpose is to find out if it is economically feasible to extract energy and chemicals out of hydrothermal systems at supercritical conditions. The first well drilled yielded superheated steam after drilling into magma at roughly 2 km depth. The second well is planned to be drilled in Reykjanes. Orkustofnun also supports a few projects coordinated by the Icelandic Research Cluster GEORG, e.g. the Deep Roots for Geothermal Systems (DRG-project) aimed at research of the roots of magma-driven high temperature geothermal systems.Drilling success has been on average 74% in Iceland into high temperature systems for electricity generation (Sveinbjörnsson, 2014). In total 105 wells were used in year 2013 to generate electricity and hence the average well is contributing 6.3 MW of electric power and generating 50 GWh of electricity. The average high temperature well is 1866 m deep, cased down to 1585 m. For low temperature systems in total 173 wells are used and 9 hot springs with an average depth of 1055 m, cased down to 223 m (Oddsdóttir and Ketilsson, 2012).
Figure 7: Comparison of energy prices for residential heating mid-year 2014 is USD cents per kWh of heat.
2.3 Master Plan for New Projects
Earlier energy developments in Iceland were focused on meeting the basic energy needs of the society for space heating and electricity for the general market. Through the years it has become more and more evident that utilisation of energy resources (as other development) must take into account not only the energy needs and the economic aspects of the development, but also a range of other interests as well. This includes other land uses and the impact of development on the environment and the cultural heritage. The first step towards such an evaluation was undertaken by a collaboration committee of specialists from the Ministry of Industry, the National Power Company, Orkustofnun and the Nature Conservation Council. This committee was active during the 1970’s to the 1990’s. It discussed plans for various electrical power plants with special emphasis on the natural conservation aspects of the projects. A general view on the energy policy and the nature conservation policy was needed for the country. This became even more important by 1994 when the Parliament of Iceland passed the first Act on Environmental Impact Assessment. The Icelandic Government published a white paper on sustainability in the Icelandic society in 1997. There the need of the development of a long term Master Plan for energy use in Iceland was once again stressed. All proposed projects should be evaluated and categorized on the basis of energy efficiency and economics, as well as, on the basis of the impact that the power developments would have on the environment.A Master Plan of this kind is comparable to the planning of land use and land protection in a strategic environmental assessment (SEA) process. It is not supposed to go into the details required for environmental impact assessment (EIA). The vision is to prepare an overview of the various potential energy projects in hydro and geothermal and to evaluate and rank these based on their energy and economic potential, feasibility, national economy and the estimated impact that each project would have on nature, environment, cultural heritage and the society, as well as the potential for other uses of the areas in question. The Master Plan should be based on the best available scientific information and conclusions should be transparent and reproducible and made available to the public. It was considered of vital importance to establish public confidence in the evaluation process.The Master Plan aims to identify power projects that rank high from an economical point of view, have a minimum negative impact on the environment, and a positive impact on the society. Such a score card for the energy projects helps decision makers to filter out which of the proposed projects are likely to become controversial and disputed and which ones not. It also directs attention to those project areas that might have protection value and should be left untouched by human development.A method for evaluating and ranking energy alternatives based on impact upon the natural environment and cultural heritage was developed as part of the first phase of the Master Plan for the use of hydropower and geothermal energy in 1999 to 2003. The three step procedure involved assessing i) site values, ii) development impacts within a multi-criteria analysis, and iii) ranking the alternatives from worst to best choice from an environmental–cultural heritage point of view. The natural environment was treated as four main classes (landscape+wilderness, geology+hydrology, species, and ecosystem/habitat types+soils), while cultural heritage constituted one class. Values and impacts were assessed within a common matrix of 6 agglomerated attributes: 1) diversity, richness, 2) rarity, 3) size (area), completeness, pristineness, 4) information (epistemological, typological, scientific and educational) and symbolic value, 5) international responsibility, and 6) scenic value.
Figure 8: Flow diagram illustrating the processes around the Master Plan.
The Government decided to use the work on the Master Plan to establish a permanent planning tool, with regular re-evaluation phases followed by subsequent confirmation of the Master Plan by Parliament. For that purpose, a new Act on a Master Plan for Protection and Development of Energy Resources (Master Plan) was passed in Parliament in May 2011. According to the Act the Minister for the Environment, shall in co-operation with the Minister of Industry, at least every four years, propose a Master Plan to the Parliament. The Master Plan shall divide the different projects in three categories, projects for utilisation, projects awaiting further research or projects in areas appropriate for protection. A total number of 84 potential power projects were evaluated during the second phase in 2011 and a Master Plan ranking 28 hydropower projects and 38 geothermal projects approved by the Parliament in 2012.The flow diagram in Figure 8 illustrates the processes around the Master Plan before the feasibility of a geothermal system is analysed in detail and Figure 9 shows proposed sites of power plant development. After the steering committee has decided that resources in a designated area should be harnessed, protected or further studied, the projects themselves can be re-evaluated and hence subject to review again by the Master Plan until the municipalities have adjusted their regional plans. The municipalities could also take the initiative to designate a certain area for protection and another area for re-evaluation. This process of re-evaluation is necessary because with increased understanding on the effects of these projects and with technological advancements, assumptions can change. This re-evaluation is relative until either the area has been formally protected or licenses for the power plant have been issued. Administrative bodies can grant licenses relating to projects that are categorized for utilisation and all research that does not require licensing can be carried out. Administrative bodies cannot grant licenses for projects that await further research if the intended work requires assessment of environmental impact. Research that does not require licensing can be carried out in these areas with the same restriction. Administrative bodies cannot grant any licenses for projects that are in areas categorized for protection except for a limited research license for prospecting on surface without affecting the environment. The projects in question are approved by Orkustofnun before submittal to the Steering Committee and can both be state owned and privately owned. Before presenting the proposal to Parliament the Steering Committee of the Master Plan must ask for both written comments and publicise the draft proposal. After the confirmation of the Parliament, the Master Plan is valid and binding for all parties for up to four years, unless the Parliament changes its resolution. The municipalities are required to adjust their regional plans accordingly within 15 years from the decision of the Parliament. In Figure 8 this process is illustrated. The Master Plan only covers projects that have the potential of at least 10 MW electric or at least a thermal potential of 50 MW. The plan is binding for all municipalities and is to be included in their general land use plans.

The ownership of resources in the ground is attached to a private land, while on public land resources in the ground are the property of the State of Iceland, unless others can prove their right of ownership. Even though the ownership of resources is based on the ownership of land, research and utilisation is subject to licensing according to the Act on Survey and Utilisation of Ground Resources, No. 57/1998 (Resource Act) and the Electricity Act, No. 65/2003. Survey, utilisation and other development pursuant to these Acts are also subject to the Nature Conservation Act, Planning and Building Act, Environmental Impact Assessment Act and other Acts relating to the survey and utilisation of land and land benefits.The Ministry of Industries and Innovation is the head organisation of energy matters in Iceland. The Ministry has today two ministers, Minister of Industry and Commerce and Minister of Fisheries and Agriculture. The Ministry has authority of the Resource Act and the Electricity Act which are the two main legal acts that geothermal energy exploration and utilisation is based on in Iceland.Orkustofnun is a government agency under the Ministry of Industries and Innovation. Orkustofnun works on the basis of the Act on Orkustofnun no. 87/2003. The main responsibilities have been to advise the government of Iceland on energy issues and related topics, promote energy research and administer development and exploitation of the energy resources. Orkustofnun is also responsible for gathering, guarding and mediating information on energy resources and their exploitation. It has been responsible for the regulation of the fore mentioned Acts, among other Acts such as the Act on Prospecting, Exploration and Production of Hydrocarbons, the Water Act and the Act on the Ownership of the Icelandic State of the Resources of the Sea Floor. More recently Orkustofnun has received the responsibility of granting licenses for exploration and exploitation of natural resources as well as all licenses according to the Electricity Act, thus acquiring full independence regarding the granting of licenses based on the Acts regulated by Orkustofnun. Figure 10 gives an overview of the role of Orkustofnun and the two ruling committees that decisions of Orkustofnun can be appealed to.In 2008 the Parliament decided to prevent any further sale of water resources, including geothermal energy, to private entities. As of that same year, all natural resources that were not privately owned were guaranteed to remain in the possession of the State. As described previously the State can grant licenses for utilisation, for up to 65 years, according to the Resource Act. As of that same year the Parliament also decided to implement into the Act, a clause stating that the Minister of Energy could delegate the power to grant licenses to Orkustofnun. Prior to that time, the Minister himself granted such licenses. The decisions made by Orkustofnun, derived from the newly granted power, could be appealed to the Ministry for revision. In that way, civilians had the possibility to have a decision revised in the administrative sector, without having to turn to the courts. Another amendment that same year dictates that CHP power plants are obliged to keep separate accounts for heat and power production to prevent cross subsidisation of electricity. Producers of electricity compete in an open market in Iceland whereas the heat is sold based on a natural monopoly license to sell heat within a certain area, hence, it is necessary to keep financial records separate in relation to e.g. the Administrative Act, No. 37/1993 as well as Art. 65 of the Icelandic Constitution. Later, or in 2012, the Parliament decided to move that same license granting power to Orkustofnun by amending the law, making Orkustofnun fully independent in its decision making. Such decisions can today be appealed to the Appeals Committee for Environmental and Resource Matters as previously mentioned (see Figure 10).
3.1 Resource Act
The Resource Act covers resources in the ground, at the bottom of rivers and lakes and at the bottom of the sea within netting limits. The Act also covers surveys of hydropower for the generation of electricity. The term resource applies to any element, compound and energy that can be extracted from the earth, whether in solid, liquid or gaseous form, regardless of the temperature at which they may be found.
Figure 10: Role of Orkustofnun as a licensing authority and the two ruling committees that can be appealed to.
According to the Act, Orkustofnun is permitted to take the initiative in and/or give instructions on surveying and prospecting for resources in the ground anywhere in the country, regardless of whether the owner of the land has himself or herself begun such surveying or prospecting or permitted others such surveying or prospecting, unless the party in question holds a valid prospecting licence pursuant to the Act. In the same way, Orkustofnun may permit others to survey or prospect, in which case a prospecting licence shall be issued to them. A prospecting licence confers the right to search for the resource in question within a specific area during the term of the licence, survey extent, quantity and potential yield and to observe in other respects the terms which are laid down in the Act and which Orkustofnun considers necessary.The utilisation of resources in the ground is subject to a licence from Orkustofnun, whether it involves utilisation on private land or public land, with the exceptions provided for in the Act. A landowner does not have priority to an utilisation licence for resources on his or her land, unless such an owner has previously been issued a prospecting licence. An utilisation licence permits the licence holder to extract and use the resource in question during the term of the licence to the extent and on the terms laid down in the Act and regarded necessary by Orkustofnun. Before the holder of an utilisation licence begins extraction on private land the holder needs to reach an agreement with the landowner on compensation for the resource or obtain permission for expropriation and request assessment. In the event that neither an agreement is made on compensation nor expropriation requested within 60 days immediately following the date of issue of an utilisation licence, the licence shall be cancelled. The same applies if utilisation on the basis of the licence has not started within three years of the issuance of the licence. This also applies to the utilisation of resources on public land.Orkustofnun may revoke the above licences if their conditions are not fulfilled. If a licence holder does not comply with the conditions established in the licence or contracts relating to the licence, Orkustofnun shall issue a written warning and provide time limits for rectification. Should the licence holder not comply with such a warning, the licence shall be revoked.
3.2 Electricity Act
According to the Electricity Act a licence issued by Orkustofnun is required to construct and operate a power plant. However, such a licence is not required for power plants with a rated capacity of less than 1 MW, unless the energy produced is delivered into the distribution system of a distribution system operator or into the national transmission grid. The owners of power plants with a rated capacity of 30–1000 kW shall submit technical details of the plant to Orkustofnun. Also, Orkustofnun shall be informed annually of the total generation of power plants with a rated capacity of over 100 kW.
4. OFFICIAL MONITORING
In June 1999 the Icelandic Parliament passed Act on Official Monitoring no. 27/1999 in order to promote efficient yet beneficial monitoring pratice. The objective of this act is to ensure that official monitoring is conducted in the most economic way possible, both for the State and for those the monitoring is aimed at. The official monitoring rules have to be effective in order for it to serve its aims. According to Art. 2, the objective of the Act is also to ensure that official monitoring rules promote the welfare of the Nation, safety and public health, safety of property, environmental protection, normal business practices and consumer protection. The Official Monitoring Act requires authorities to conduct an economic evaluation before new monitoring rules are passed as law, to ensure that the extent of the monitoring is reasonable in proportion to the objectives aimed for. The monitoring should not be more extensive or more complex in execution than is required to achieve the distinctive objectives.The official monitoring of utilisation of geothermal resources in Iceland is rather extensive and is the responsibility of different public authorities, as will later be addressed. The objective of the monitoring for each sector is different, respectively: to protect the environment, to prevent overexploitation of the resource, and to secure occupational safety and safety of delivery at the power plants as outlined in the following sections.
The objective of official monitoring of the environment surrounding geothermal projects in Iceland is reflected in the stated aims of Art. 1 of the Nature Protection Act no. 44/1999. The objective is to regulate the interaction of man with his environment so that it harms neither the biosphere nor the geosphere, nor pollutes the air, sea or water. The ultimate aim is to ensure that the Icelandic ecosystem can develop according to its own laws and to ensure the conservation of its exceptional or historical aspects. An important pillar in environmental protection according to Icelandic legislation is Act on Environmental Impact Assessment no. 106/2000 (EIA) as previously mentioned. The objective of the EIA is to gauge the effects a project may have on the environment and to minimise as far as possible the negative environmental impact of projects. Furthermore, when resource utilisation and power plant licenses are issued, environmental factors should be taken into consideration. Surveying, utilisation and power plant licenses may be bound by specific conditions in order to safeguard environmental requirements, according to the Resources Act, Art. 17 and the Electricity Act, Art. 5. With the Strategic Environmental Assessment Act no. 105/2006 (SEA), Iceland adopted Directive 2001/42/EC from the European Parliament and the Council as previously mentioned. The objective of the Directive is to protect the environment and to encourage sustainable development by conducting an environmental assessment of plans which are likely to have an impact on the environment. In the Directive it is assumed that the impact of plans and programmes on the environment are assessed before they are passed and executed.The Health communities are responsible for official monitoring of the operation license. These committees derive their power from the Hygienic & Pollution Act no. 7/1998. The Act divides Iceland into ten regulatory zones and each zone has one committee. The operation licenses for power plants are issued by these health committees. The objective of these licenses is to prevent pollution from e.g. run-off water and to promote a clean environment. The operation license is equipped with conditions and the health committees oversee that these conditions are met. Failure to do so can result in official warnings, daily penalties and termination of the license.
4.2 Resource monitoring
Another objective of official monitoring of utilisation of geothermal resources is to ensure that the most efficient exploitation of the resource is adopted in the long run and that extraction of geothermal fluid does not exceed levels deemed necessary, according to Art. 25 of the Resource Act. One way to ensure this is to have effective official monitoring of the utilisation taking place at every geothermal project. Besides efficient monitoring it is also important that relevant institutions, municipalities and developers are aware of the fact that utilisation of geothermal energy in Iceland is to be conducted as stipulated in Art. 25 of the Resource Act. Some natural resources are exhaustible, therefore it has been considered necessary to apply rules to manage their utilisation, in order to ensure natural resources are protected and maintained for future generations. Orkustofnun has the responsibility to monitor geothermal areas being researched or utilised, according to the Resource Act. Orkustofnun is also responsible for the official monitoring stipulated in the Electricity Act. Appendices within utilization licenses and power plant licenses stipulate what detailed information a developer is supposed topresent annually to Orkustofnun. The information required is as follows: The amount of fluid extracted or reinjected into each well in the geothermal field, each month.
The temperature of the water reinjected into the geothermal reservoir each month.
Results of water level measurements in wells where the water level can be measured and are within the geothermal field.
The pressure changes or drawdown determined in the geothermal reservoir.
The results of measurements of the enthalpy of the fluid from every production well in the geothermal field.
Chemical analysis of the geothermal water (and steam, if appropriate).
Results from simulations of the geothermal reservoir.
Results of measurements made to monitor changes in the geothermal reservoir.
Information on drilling in the industrial area.
A resume of improved understanding of the physical characteristics of the geothermal reservoir based on the results of latest drilling.
The above mentioned items should provide all the necessary information for the monitoring authority to monitor the utilisation of the resource. Furthermore Orkustofnun has stipulated certain limits on drawdown within the geothermal systems of the last three utilisation licenses for geothermal power plants. This is done to maintain long term balance of water in place, in order to secure the possibility of continuing carrying heat in place to the surface using water as the carrier. An example is given in Figure 11 for actual drawdown limitations stipulated in an utilisation license issued in year 2014 of the Þeistareykir Geothermal Power Plant proposed by Landsvirkjun to be built in the next years. In addition to limitation of drawdown there are also limitations in terms of annual reduction in steam supply to be no more than 3%. If those limits are reached Landsvirkjun is required to take the necessary steps in mitigating the effects by calibrating the reservoir model and predicting again whether the geothermal system can sustain enough yield through the lifetime of the power plant. The prediction is given with a calculated probability margin taking uncertainty into account. If the drawdown goes beyond the error margin the license holder needs to re-evaluate the reservoir model, change the extraction levels within the area or increase reinjection into the same geological formation to maintain long-term water balance. Figure 11: Limitations of drawdown to ensure long-term utilisation of the resource. The vertical scale shows pressuredrawdown from natural state in bars. The horizontal scale is in years of operation with an uncertainty margin(Orkustofnun, 2014).
4.3 Safety and management
The objective of monitoring utilisation of geothermal energy does not only entail monitoring of the surrounding environment and the resource. The third objective of monitoring of geothermal projects is to ensure the safe and responsible management of power plants which generate electricity from geothermal energy. Monitoring of a power plant starts before construction of the plant begins. First, the municipal authority in the area where the power plant is to be built issues a development license or a building license, according to the Planning and Building Act no. 73/1997. According to Paragr. 2 in Art. 38 it is the local authority’s responsibility to monitorpower plant development and its surroundings, according to the terms of the development or building license that it has issued for the power plant. The council is to make sure that all buildings are built according to the development plan, rules and regulations. Second, a power plant license is required in order to build and operate a power plant, according to Art. 4 of the Electricity Act. Orkustofnun is responsible for official monitoring of the conditions stipulated in the relevant license. The objective of monitoring after generation of electricity at the power plant has begun is to ensure that operations are conducted according to the requirements of the Act. On-site monitoring at the power plant, quality of electricity, security of supply of electricity and accounting should be as stipulated in the Electricity Act.4.4 Reaching the objectivesAccording to Official Monitoring Act the objective is to ensure that official monitoring rules promote the welfare of the Nation, safety and public health, safety of property, environmental protection, normal business practices and consumer protection. In Paragr. 4 in Art. 9 of the derivative Regulation of the Official Monitoring Act it is stipulated that the requirements of individual official monitoring authorities is to be harmonised and the monitoring implemented by one and the same party to the greatest possible extent.The objectives formulated in the legislation concerning the arrangements for official monitoring of utilisation are in general being reached, especially with regard to the preparation phase for utilisation, environmental protection and the construction phase.
This paper gives a short overview of the national policy, legal framework and official monitoring of geothermal resources in Iceland. Utilisation of geothermal resources has expanded rapidly during the last decade. Electricity generation is estimated to increase by 12% from 5.2 TWh in year 2014 to 5.8 TWh in year 2020 and heating with geothermal from 28,1 PJ in year 2014 to 34 PJ in year 2020. Iceland’s long term objective is to ensure long term utilisation of its resources and the legal amendments mentioned earlier, as well as the future implementation of the Master Plan for hydro and geothermal energy resources in Iceland are steps in maintaining and sustaining this objective. Iceland has developed a great deal of know-how and experience in harnessing of geothermal resources, both for space heating and electricity generation.A few major amendments have recently been made to the legal framework in Iceland that concerns geothermal development. These amendments were made with the goal of clarifying the rules regarding ownership of natural resources as well as making the division between production based on exclusive licenses and production on the open market more conclusive. On top of that the shift of power to grant licenses was made with a comparative goal in mind, which is efficiency. Orkustofnun is now purely an administrative agency when it comes to granting licenses and its decisions can be appealed to a ruling committee.Geothermal energy plays an important role in providing the nation with clean and reliable energy and is fundamental to the Icelandic economy as well as Icelandic welfare and independence. The rules and procedures of official monitoring in Iceland have been explained in this article in a concise manner. The legal framework itself is extensive and counting derivative regulations, the law on the matter is vast. Some of the legislation is recent while other branches are long-standing. Effective policy making and official monitoring of geothermal development for sustaining a renewable energy society in Iceland is crucial for sustaining a long-term lifespan of the resource.
