FINDINGS
1. Approximately 1,400 persons attended the World
Geothermal Congress in Antalya, Turkey, during 24-29
April 2005. This was the largest meeting ever held devoted
exclusively to geothermal energy. The Congress was sponsored by the International Geothermal Association (IGA)
and the Turkish Geothermal Association (TGA). Delegatescame from 81 countries, representing all 6 continents.
Previous Congresses had been held in Italy (1995) andJapan (2000).
2. Over 700 papers were presented, and published in a CD,
covering every aspect of resource exploration, well fielddevelopment, electric power generation, district hot-water
heating, direct-use and geothermal heat pumps, balneology and recreational uses, project finance and economics,
public policy, and environmental benefits and protection,
all related to geothermal energy.
3. Keynote speakers included the Government Ministers
holding the portfolio for energy from Indonesia, Iceland,
the Philippines and Turkey, as well as ranking representatives of the European Commission, and the Governmentof Germany, plus the Minister of Environment of Turkey.
They, and leading representatives of industry and academia,
stressed several congruent points:a) There are significant environmental benefits from
replacing fossil fuels with geothermal energy, including
a reduction in greenhouse gas emissions.
b) There is an urgent need for increased investment in
geothermal demonstration and development projects
by government and international agencies.
c) There is an urgent need in many countries for legislation authorizing private investment in and ownershipof geothermal energy projects.

d) The record shows an increasing level of successful development and utilization of geothermal energy, with utilizationin over 75 countries worldwide, serving over 100 million people.
e) Development and utilization of abundant, indigenous geothermal energy is proving a means of freeing many countries from costly and often unreliable import of petroleum.
f) There is a need for policy statements by government and international agencies in which the preferential development and utilization of geothermal energy is promoted as a primary energy goal.
g) The utilization of geothermal energy will be accelerated if national energy development goals specify a fixed percentage
of future energy consumption to be reserved for geothermal and other environmentally friendly energy sources.
4. Regarding technological developments, several speakers reported on:a) improvements in electric power generation using low-enthalpy fluids, thus increasing the efficiency of utilization andthe size of available reserves, and greatly expanding the geographical area in which use is economically attractive;b) the sustainability of geothermal fields under various management strategies, reflecting either satisfying the immediate national needs for energy, or providing a long-term phased development;c) the approaching commercial development of enhanced geothermal systems (including hot dry rock systems) inwhich water is injected into relatively impermeable rock to extract heat energy;d) the economic advantages to be gained by trading carbon credits, based on the favourable chemistry and emissions
profile of geothermal energy, ande) increased utilization of heat pumps to extract heat energy from very shallow holes as an efficient and economicallyattractive means of home heating and cooling.
5. At present, the installed geothermal electric generating capacity is over 8,900 MWe in 24 countries. This has increased
at about 6.5% annually since 1975, with fluctuations reflecting economic cycles. The leading countries in geothermal
electric generation are the Philippines, the United States, Indonesia, Italy, Mexico, Japan, Iceland and New Zealand.
Recent additions to geothermal electric generation also have come in Papua New Guinea, Portugal (the Azores), Kenya,
Germany, Costa Rica, Russia and Austria.
6. Non-electric utilization (‘direct use’) of geothermal resources in 71 countries totals nearly 28,000 MWt, including the
new geothermal heat pump technology. Growth in installed capacity has been about 11% annually since 1975. Leading
nations include China, Sweden, the United States, Iceland, Turkey and Japan. In Iceland, over 85% of space heating comesfrom geothermal energy.
7. It was agreed that the next World Geothermal Congress will be held in Bali, Indonesia in the year 2010. In the interim,
meetings will be held by regional affiliates of the IGA.

RECOMMENDATIONS

1. It is urged that nations and multinational groups adopt energy policy statements that give a preferred status to thedevelopment and utilization of geothermal energy. This can be done through a variety of ways:a) Acknowledgement of the environmentally benign (‘green’) nature of geothermal energy.
b) Encouraging the trading of geothermal carbon credits.
c) Requiring that a minimum percentage of future energy supply be reserved for geothermal energy and related ‘green’sources of energy.
d) Recognizing formally that the utilization of indigenous geothermal energy results in a reduction in oil imports, orconversely allows a greater percentage of domestic petroleum to be exported, both having favourable impact onnational balance of payments.
e) Establishing a preferential pricing schedule for geothermal energy.
2. It is urged that national legislatures speedily adopt legislation:a) allowing the investment by private organizations and individuals in the development of geothermal resources and in
the ownership of facilities that produce and utilize geothermal energy;b) streamlining the permitting and resource allocation procedures;c) providing tax incentives for organizations or individuals that explore for, produce and sell or distribute geothermalenergy within their national boundaries;d) protecting geothermal energy developments from unfair competition from hydrocarbon imports and other highpollution sources of energy by removing financial and other subsidies that help support the continued use of thosenon‑renewable energy sources;e) actively supporting geothermal energy development by:i)establishment of policies favouring geothermal energy;ii)
placing a ‘pollution tax’ on hydrocarbon and other high-pollution energy sources;iii)
providing grants for geothermal demonstration projects, new technology, and projects in regions not adequately served by existing energy suppliers;
iv)
provision of loan guarantees and insurance policies for environmentally benign geothermal energy projects.

3. Because of the growing need for geothermal scientists, engineers and technicians, it is urged that national legislaturesand multinational institutions:a) sponsor and financially support training programs at the technical institute and university level;b) provide scholarships for students to attend these institutions;c) sponsor and financially support lectureships at secondary schools to educate the youth about environmental aspectsof energy utilization, especially regarding geothermal energy;d) provide endorsement and financial support for international geothermal conferences, to encourage the developmentof new technology and the exchange of ideas and experiences, ande) encourage participation by indigenous groups who are landowners and the guardians of the resource in many countries.
4. It is urged that national and multinational organizations continue to support programmes of geothermal explorationand development, even in high-risk environments, through grants, non-recourse loans, loan guarantees, and related
financial measures, so that less-developed regions may benefit from the utilization of geothermal energy.
5. It is urged that, in nations experiencing energy shortages, the multinational organizations take an active role in speeding the development of geothermal energy. This can be done through accelerated programmes of financing, provision oftechnical and management expertise, and project reviews and approvals.

Editor´s Note: Invitation from Geothermics
Marcelo Lippmann and Marnell Dickson, Editor and Associate Editor of the journal Geothermics, the International
Journal of Geothermal Research and its Applications, which is published under the auspices of IGA, have asked me
to pass on an invitation to members of the Association to submit papers to Geothermics. You might be interested inreading their recent editorial.
Editorial published in Geothermics Vol. 35, No. 1 (February 2006)
The changes in recent years in the energy market and in business in general, along with government policies, have all had an influence, whether direct or indirect, on the type and number of manuscripts submitted to Geothermics.
The rising cost of fossil fuels, particularly of oil derivatives and natural gas used in the generation of electricity, in space heating
and in industrial processes, has admittedly given a welcome boost to geothermal development, though this has not been felt uniformly
across the board. The direct uses are growing at a faster rate, in terms of numbers of projects, than the geothermal electric power sector. Our readers will no doubt have noticed a corresponding rise in the number of articles dealing with direct applications, which are
only a part of the many manuscripts submitted in recent years on this topic.
Governments all over the world have been implementing laws and regulations and offering incentives (or disincentives) that promote (or ignore) the development and use of renewable energy resources; these differ significantly from country to country. In thecase of geothermal there has been an overall reduction in the funds allocated to R & D by governments and international agencies. In
a few cases the decision-makers have adopted the view that geothermal is a “mature industry” and consequently no longer in need ofgovernment support, while continuing to help the fossil fuel and nuclear industries and the development of other renewables. This has
led to cutbacks in funding for research groups that have been involved in geothermal energy for many years, and even to the closureof the training courses held annually (for almost 25 years) in Auckland, New Zealand, in Kyushu, Japan, and in Pisa, Italy. The net
result of these policies is that there are fewer researchers and students working on geothermal-related issues these days. On top of that,and paraphrasing one of our Board members, “despite the great legacy of some countries, mine is terribly underfunded, with aging
demographics trending towards a reduction in overall knowledge and capability”.
Another negative influence on the number of manuscripts submitted to the journal is the increasing tendency to withhold
permission to publish data. In many countries, privatization of geothermal activities has meant less incentive to spend funds on
R&D, and a distinct reluctance to disseminate information that might prove useful to the competition. Although major researchis still being done, the companies are driving their technical personnel to complete exploration and development work as fast
as possible, leaving very little time for them to gather their wits and prepare manuscripts that are good enough for publication.
The combined result of all these factors is, unfortunately, a reduction in the number and breadth of R&D projects, and the draftingof far fewer scientific papers providing information on the latest theoretical, laboratory and field studies.
Despite the bleak scenario that we have just described, not all hope is lost, neither for geothermal R&D, nor for Geothermics.
Three important geothermal conferences were held in 2005, whose participants were able to present the results of their projects
and share their problems and successes with colleagues. All three were well attended: about 130 registered participants at the 30th
Stanford Workshop on Geothermal Reservoir Engineering, around 1300 at the World Geothermal Congress 2005, and about 500 at the
Geothermal Resources Council 2005 Annual Meeting. Attendance at the GRC meeting was indeed the largest since 1997. This showsthat there is still a strong interest in geothermal energy and encourages us to think that, with appropriate “prodding”, our colleagues
could be convinced of the importance of publishing the results of their work. We can all benefit from the experience of others.
IGA News, January – March 2006
During this last year, the “editorial team” of Geothermics (i.e., Stefano Bellani, Joe Moore and ourselves) has invited
potential authors to send in manuscripts on a number of occasions. The results have not been as positive as we expected, probably because of the factors we have just discussed. To keep Geothermics as the leading “international journal
devoted to the research and development of geothermal energy”, however, we must have a ready supply of good quality material. In an Editorial exactly a year ago, you were all invited to submit your papers to the journal. We would like toextend this invitation once again, with the promise that we will do our best to process and publish them as soon as possible.

EUROPE
Renewable Energies for Heating and Cooling:
Dinner Debate in the European Parliament in Brussels
Burkhard Sanner, President EGECEUFORES (a group of Members of the European Parliament interested in renewable energies) and EREC, theEuropean Renewable Energy Council, organized a meeting of relevant people from politics, administration and industry
on 6 December in the restaurant of the European Parliament in Brussels. Mechthild Rothe, German MEP and presidentof EUFORES, welcomed MEPs from different parties, officers from the European Commission, policy and energy
experts, industry representatives, and others, including former MEP Eryl McNally, one of the key supporters of renew‑
able energies in the last decade. Among the MEPs were some key actors for renewable energy; beside Mechthild Rothe,
Fiona Hall (UK), Peter Liese (Germany) and Claude Turmes (Luxembourg) were also present.
The goal of the event was to show the importance of the still‑missing pillar in the EU’s renewable energy support
activities - the heating and cooling sector. A European Directive on Electricity from Renewable Energies has existed
since 2001 and the Biofuels Directive is on its way for the transport sector, but for the largest energy consumption sec‑
tor - heat, with almost 40 % of the total - no EU-wide support regulations are in place. Without the heating and cooling
sector, the targets set for the European Union in the Kyoto process (the “White Book” targets) and the target of 12.5 %of renewables in all energy supply by the year 2010 cannot be met. It is even more critical to the longer-term targets
for 2020 (Turmes-report) and 2040.
EGEC and fellow EREC members have called for a suitable European Union directive to increase the share of renew‑
able energies in the heating and cooling sector. This was underlined at the EGEC Business Seminar 2005 in Berlin,
where the relevant EREC-brochure had been presented on 6 April, listing all the reasons and need for such a directive.
It can be downloaded from:http://www.erec-renewables.org/documents/RES-H/EREC_RES-H.pdf.
At the dinner debate in Brussels the main speaker, Ole Pilgard, president of the European Solar Thermal Industry
Federation and one of the directors of EREC, explained again the need to foster renewable sources for heating andcooling in order to achieve the targets. Three speakers from the associations for geothermal, solar thermal and biomass
promoted the potential of their respective technologies, while the participants enjoyed a light but tasty dinner. A lively
discussion followed, and in total the event was a clear signal to the MEPs to discuss favourably the draft initiative reporton the need for such a directive. This draft report is currently before the relevant committee of the European Parliament
and will be put to the vote in the plenary early next year. It is also hoped that the representatives of the European
Commission will acknowledge this clear signal and follow the Parliament report by submitting a draft directive on heat‑ing and cooling from renewable energy sources.
On the day after the dinner debate, the European Commission released a statement concerning the RES-Heat direc‑
tive, in item 2.1 (“Legislation on renewable energy in heating”) of the EC Communication on the Biomass Action Plan:“This is the missing piece of the jigsaw, alongside existing directives covering electricity and transport. The Commission
will work towards this legislation in 2006.”

European committee adopts report calling for a Green Heat target
Reproduced from Refocus, the international renewable energy magazine, issue 181, by permission of Elsevier Ltd.
BRUSSELS, Belgium, February 1, 2006 (Refocus Weekly) The energy committee of the European Parliament has
adopted a report which recommends countries set ambitious targets to increase the share of green heat technologies by
2020.
The Committee on Industry, Research & Energy adopted the Initiative Report on Renewable Heating & Cooling presented by German member of Parliament, Mechtild Rothe, by a vote of 39 to 0, with three abstentions. The report callson the European Commission to propose a directive to promote heating and cooling from renewable energies, which
would substantially contribute to increasing the security of the continent’s energy supplies and to reducing dependenceon oil and natural gas.
“We expect that Rothe’s Initiative Report will receive a similarly clear vote in the European Parliament’s plenary andhope that the European Commission will soon present a Directive proposal,” says Raffaele Piria of the European Solar
Thermal Industry Federation. The group expressed satisfaction with the vote despite a significant weakening of someissues in Rothe’s original text that was released late last year.
Targets for green heat should consider the current national shares of space conditioning and water heating,and the potential for solar thermal, earth energy / geothermal, and biomass in each country. The committee had
debated the term ‘binding’ but a vote of 21 to 15 agreed to retain “binding targets” contained in the original version.
The report does not suggest that national support schemes be harmonized at the EU level, but it proposes to agree on
general principles for support schemes to be adopted and a range of instruments such as tax breaks, financial incentives
or regulatory measures. It also proposes measures to reduce the administrative barriers to the use of green heating andcooling.
ESTIF represents manufacturers and service providers in the solar thermal sector, and promotes acceptance for solar
thermal as a key element for heating and cooling in Europe.

RussiaObituary - Vladimir Kononov 01.01.1932 – 25.12.2005
Scientific Council on Geothermal Problems of the Russian Academy of Sciences
Vladimir Ivanovich Kononov, Main Reseacher of theGeological Institute of the Russian Academy of Sciences, Doctorof Sciences (Geology and Mineralogy), Member of the Russian
Academy of Natural Sciences and the pre-eminent scientist in
the field of hydrogeology, hydrochemistry and hydrogeother‑mics died on December 25, 2005.
V.I. Kononov graduated from the hydrogeological faculty of
the Moscow Geological Prospecting Institute in 1954 and joined
the Laboratory of Hydrogeology and Engineering Geology
Problems of the USSR Academy of Sciences, where he studied
the influence of water and other natural factors on the processof underground gasification of coals. After reorganization of thisLaboratory in 1961 he worked in the Geological Institute of theRussian Academy of Sciences until the end of his life.
There were some basic directions in his scientific activity.
The first one was development of general theoretical ques‑
tions of hydrogeology: hydrophysical zonation of the Earth’s
crust, formation of chemical compounds of underground waters, their genesis and classification.
The second direction consisted in regional researches based on the comparative analysis of thermal waters from differ‑ent areas of modern volcanism in Kamchatka, Kuriles and many foreign countries. He took part in long-term geodynamic
expeditions of the USSR Academy of Sciences to Iceland. Then he studied thermal fluids in the Transmexican volcanic belt
and its surroundings during several field trips. He revealed the distinctions in composition of deep high-temperature fluids
in island arcs and rift zones, he identified some genetic types of fluids (including earlier unknown “hydrogen” v. “methane”
steam-water mixtures), and he proposed a new classification of thermal waters in volcanic areas, reflecting specificity of theirinteraction with rocks and with heat sources in various geo-tectonic conditions.
IGA News, January – March 2006


The third direction involved studying various aspects of hydrothermal activity, i.e. the basic regularities of formation ofthermal waters, their roles in transfer of deep heat, mass balance in hydrothermal systems and the effect of their discharge at theocean floor. He carried on marine geothermal researches in the Caribbean-Mexican region of the Atlantic Ocean and in the areaof the Central-American trench of the Pacific Ocean, heading several cruises of the RV “Academician Nikolay Strakhov”.
Finally, the fourth direction was connected with an estimation of the prospects for use of hydrothermal resources in anational economy as an energy source and a mineral raw material. With this purpose he carried out researches in the Caucasus,in CisCaucasia, Baykal Rift Zone, Kuriles-Kamchatka region and in other areas of the country. One result of his long-term
efforts on the organization of practical use of deep heat was the construction of the large Mutnovsky geothermal power stationon Kamchatka.
V.I. Kononov published over 200 scientific works and 12 monographs, which are widely known in Russia and abroad.
About 30 of his works are issued in English, French, Spanish and Icelandic. His monograph “ Geochemistry of thermal watersof areas of modern volcanism (in rift zones and island arcs)”, in Science, 1983, received wide acclaim.
V.I. Kononov gave much force and a lot of time to organization of scientific work. In the Geological Institute he man‑aged the Laboratory of Geothermics (1972-1986) and the Laboratory of Geoenergy and Hydrogeochemistry (1986-1997).
Since 1989 he was the Chairman of the Scientific Council on Geothermal Problems of the Russian Academy of Sciences.
V.I. Kononov was also a member of the Scientific Council of the USSR Academy of Sciences on Engineering Geology andHydrogeology, the Bureau of the hydrogeology section of National Committee of Geologists of the USSR, the ScientificCouncils of the Geological Institute RAS and VSEGINGEO, editorial boards of magazines “Proceedings of the Academy of
Sciences, 'A' series, Geological” (1990-1992), “Lithology and mineral resources” (1992-2005), and “Geothermics”.
V.I.Kononov had wide international popularity. He was a member of the International Association on Hydrogeology (IAH)
and the International Geothermal Association (IGA). He worked in the Commission of thermal and mineral waters of IAH, he
was a member of the IGA Board of Directors (1992-1995) and he headed a number of the international projects.
V.I.Kononov’s activity was marked by the Diploma of Presidium of the USSR Academy of Sciences and the Russian
Academy of Sciences in connection with the 250th and 275th anniversary of the Academy of Sciences, by medals «the Veteranof Labor», «300 years to the Russian fleet» and «In memory of the 850th anniversary of Moscow ».
In recent years V.I.Kononov did not limit his activity to scientific work only. He wrote and published three editions of“Geological etudes” in which the sparkling humour and literary talent of the author was shown.
Memories of Vladimir Ivanovich Kononov will remain forever in the hearts of his colleagues, friends and relatives.

RussiaHeat and electricity from Hot Dry Rocks of Avachinsky Volcano for the Center of Kamchatka
Dr. Prof. Oleg A. Povarov, Russian Association of Geothermal Energy Society,
Dr. Viktor M. Sugrobov, Nauka SC

At the International Mineral Extraction Conference held in September this year in Petropavlovsk-Kamchatsky City,
experts and scientists discussed a proposal to radically solve the problem of heat and power supply of densely populated
Petropavlovsk-Kamchatsky City by utilizing geothermal resources located not far from the city. The proposal rests on
the idea of using accumulated heat of Hot Dry Rocks forming the magma chamber of Avachinsky Volcano. The idea was
first brought forward by V.V. Averev (1964-1967), who justified deep drilling in the pre-chamber area to study geother‑mic conditions and develop a heat extraction system. By that time the interbedded magma chamber under Avachinsky
Volcano had been discovered by geophysical methods (Institute of Volcanology, Siberian Branch of the Academy of
Sciences, USSR, Schteinberg, Zubin, 1963).
Assumptions of high temperatures in the HDR chamber (600-1000°С) and its big area, derived from geophysical andpetrological data, implied that the chamber has a big energy potential. The idea of V.V. Averev was further developedin the report on “Possibilities for utilizing heat of Avachinsky Volcano magma chamber” (Fedotov, at el,) made at theSecond United Nations’ Symposium on the development and use of geothermal resources (San Francisco, USA, 1975)(see Fig. 1).
Avachinsky Volcano is located in the vicinity of Petropavlovsk-Kamchatsky City. The distance between the volcanic
crater and the city is 25-28 km. Avachinsky Volcano, forming part of the Avachinsky Group of volcanoes, lies in a vol‑cano-tectonic depression. The maximum depth of Upper Cretaceous igneous-sedimentary rocks constituting the base‑
IGA News No. 63ment is registered directly under Avachinsky Volcano (1.5 km below the sea level). The abnormal zone associated withthe peripheral magma chamber creates a big local gravity anomaly, does not produce a significant positive magnetic
anomaly, but induces anomalies in seismic-wave propagation. Interpretation of geophysical data allows the suggest­ionthat the peripheral magma chamber of Avachinsky Volcano is deposited between the Upper Cretaceous basement andthe volcanogenic overburden. From seismic data, the depth of the chamber top edge is 1.5 km below the sea level, whilegravimetric data show that the center of the gravity anomaly is located at
the depth of 4 km. Seismic surveys reveal that the chamber area at the base‑ment level is about 5.2 ± 0.9 km in radius, with the most “heated” part ofthe chamber being 3.6 km in radius.
Continuous seismic refraction and deep seismic profiling acrossAvachinsky Volcano performed in 1982-84 in a south-easterly direction
proved the existence of a zone with higher absorption properties and seis‑mic waves velocity inversion at depths between 1.5-3 km.
The size of the Avachinsky Volcano chamber along the seismic profile
can be evaluated to be within the range of 2 and 5.2 km in radius. A smaller
radius is determined using the total magma consumption data over the rec‑ognized chamber life-period of 60 thousand years.
It is impossible to measure precisely the geometrical size and form of
the chamber by geophysical methods, due in particular to an inability toevaluate rock density. Given the depth of the main anomaly (2-6 km) and the Figure 1. Petropavlovsk-Kamchatsky
above radii, one can assume that the larger anomaly has an ellipsoidal form district heating system operating on HDR
while the smaller anomaly has the form of sphere. Respectfully the size of technology.
the chamber can be estimated within 35-350 km3.
At present utilization of the huge heat reserves of the magma chamber (of the order of 1-10 ·1020 J) can hardly berealized without a technology of drilling at high temperatures. At the same time in the pre-chamber zone the temperatureof 250°C, even in non-stationary conditions and given the chamber life-period of 20 000 years (Fedotov, at el, 1976),
can be assumed to extend over 2 km (see Fig. 2). Based on the temperature profile survey of the area around the magma
chamber, the accumulated heat potential is estimated to be of the order of n·1021 J. It becomes obvious that we should
utilize the accumulated HDR energy of the nearest pre-chamber area. For example, from 1 km3 of rocks at the depth of
5 km and 6 km distance from the volcano one can produce about 8·1017 J in
non-stationary conditions.
To utilize HDR heat it is envisaged to create within the pre-chamber area
an underground circulation system comprising deep wells. Model tempera‑ture profiles around the magma chamber justify possibilities of uncoveringby 4 km-deep wells high-temperature areas (250-400°C), including in nonstationary conditions. If we assume the chamber radius to be 5 km, verticalwells should be drilled at a distance of 6-8 km away from and south of the
volcano. Inclined wells should be drilled at a greater distance - 7-9 km fromthe volcano (see Fig. 2).
At the first stage of the project implementation, drilling of one paramet‑ric well is envisaged, aimed at confirming the existence of the temperature
anomaly in the pre-chamber zone. Further, in case of positive results, one Figure 2. Temperature profiles underor two more wells will be drilled to perform hydraulic frac tests and form Avachinsky Volcano at different depths

mined by heat demand, HDR properties and the wells’ output.
Presently heat demand in Petropavlovsk-Kamchatsky City reaches 700 Gkal/h (0.8 GJ/s). Assuming an averagetemperature in the pre-chamber zone of around 300°C and its cooling by 50°C, the circulation system’s rock volume
will be about 20 km3. Based on preliminary guidelines from French specialists from BRGM, assuming a well output
of some 25 kg/s from the circulation system and assuming a fluid enthalpy of 1080 kJ/kg, drilling at least 45 injection
and production (vertical and inclined) wells to depths between 3.5-4 km will be needed. To support the operation of thegeothermal circulation system some 1000 l/s of water will be required, which can be taken from water flows streaming
down the volcano.
At the meetings held in July and August this year in Moscow specialists from Moscow, France and Germany decided
to prepare jointly an international report on utilization of HDR of Avachinsky volcano to produce heat and electricity forthe center of Kamchatka (see Fig.1), in which exploration and exploitation of the petrothermal energy source, technicaland economic parameters of the project, and other associated issues will be thoroughly studied.

Mexico2005 Annual Congress and XIII Ordinary General Assembly of the Mexican Geothermal
Association (AGM)
Luis Gutiérrez-Negrín, Mexican Geothermal Association

On November 25, 2005, the Mexican Geothermal Association (AGM: Asociación Geotérmica Mexicana)held its Annual Congress and its XIII General Ordinary Assembly at the facilities of the Comisión Federal deElectricidad (CFE) of the Los Azufres geothermal field, located in the State of Michoacan, in central Mexico.
Seven technical papers were presented during the congress, regarding some aspects of the Cerro Prieto and
Los Azufres geothermal fields, the Mexican histories and legends related to geothermics and the submarine
geothermal resources. The proceedings were collected on a CD. Some of those papers will be published in the
Mexican magazine Geotermia (which can be read at the Geothermal Resources Council website: http://geothermal.org).
During the opening of the congress, Alejandro Abril-Gaspar, President of the AGM, read a salutation letter sent by John W. Lund, President of the International Geothermal Association (IGA), to which the AGM
belongs as a national association.
After the congress, the AGM assembly was conducted by its President, under the following agenda:
1. Approval of the Minutes from the General Extraordinary Assembly of June 15, 2005.
2. Report of the Directive Board.
3. Report of the Treasurer.
4. Presentation of the 2005 Pathé Award.
5. General issues.
The Pathé Award was recently instituted by the AGM to honour annually a person with a minimum of 15
years working in Mexican geothermics, whose professional trajectory or contributions are regarded as important. In this, its first year, the Pathé Award went to Héctor Alonso-Espinosa. He is a 69 year old Mexican
geologist who has been involved in geothermics since 1958. Between 1977 and 1989, as head of the Cerro
Prieto field and of the Mexican geothermal division of the Comisión Federal de Electricidad (CFE), he was
the executive responsible for the construction and commissioning of almost 600 MW of geothermal-electricunits in the Mexican fields of Cerro Prieto and Los Azufres. Presently, Héctor Alonso-Espinosa is a consultant
for the CFE’s geothermal division.
The AGM finished its business by taking the traditional photo, this time having as background the firstgeothermal-electric unit installed in the American continent, the one of 3.5 MW formerly operating in the
Pathé, Mexico, geothermal field, which is now on exhibition in Los Azufres.

INAGA Geothermal Seminar
Alimin Gintin
On 29 September 2005, the Indonesia Geothermal Association (INAGA), in cooperation with the IndonesianChamber of Commerce (KADIN) and the Indonesia Electricity Society (MKI), held a one-day seminar with the title“Geothermal Breakthrough for Fuel (BBM) Crisis Solution and Security of Energy Supply” in Indonesia.
The Seminar was opened by Mr. Wimpy S. Cecep on behalf of Coordinating Minister for Economy Mr.
Aburizal Bakrie and the closing remarks were made by the Minister of Energy and Mineral Resources, Mr. Purnomo
Yusgiantoro.
Background
The Indonesia archipelago has numerous active volcanoes associated with a 7,000 km long plate boundary along
which there is both convergent and strike slip movement. This has given rise to a large concentration of high tempera‑ture geothermal systems. Indonesia may have the highest geothermal potential of any nation, with a geothermal resourceof about 27,000 MWe. It is estimated to consti‑
tute 40% of the world geothermal resources.
Although Indonesia has abundant geothermal
resources, which are known to produce environ‑mentally clean energy, development of geother‑
mal energy in Indonesia is facing many chal‑lenges. Over a span of 20 years, Indonesia hasdeveloped 807 MWe of geothermal power or 4%of its geothermal potential. INAGA and IGA,
as part of the world geothermal society, need topromote geothermal utilization in Indonesia.
To date, the government program of removing
subsidies for electricity and petroleum fuel haveconsiderably aided progress toward geothermal
development. Since the fuel price is high andIndonesian oil production is limited, and there
is a need to import some fuel for domestic con‑sumption, geothermal energy may be able toreplace fossil-fired base power plant to generate
electricity.
Objectives of the Seminar were:
1. to present the current situation of geothermal development in Indonesia from all aspects i.e. legal/regulatory,
commercial, technical, institutional, etc.
2. to review and analyze whether the present situation has a positive or negative influence on achieving the
4,000 MWe target for geothermal power plant in Indonesia.
3. to make recommendations to the government of Indonesia and to the business community regarding what kindof challenge, change, and improvement should be made to the current situation to support and create a business envi‑
ronmental condusive to geothermal power development reaching 4,000 MWe by 2010.
Factors and challenges to develop geothermal in Indonesia:
1. High investment cost.
2. Limited funding and incentive mechanisms.
3. Gasoline products remain below the market price.
4. Legal and fiscal uncertainties.
5. Uncompetitive energy prices.

Speakers at this one day seminar came from geothermal developers, government (Director General of Electricity andEnergy Utilization, Secretary for Director General of Geology and Mineral Resources, Tax Department, and Indonesia
National Development Plan Board), a state-owned company, geothermal industries, observers, and others.
Some recommendations (API’s general and specific recommendations) were formulated by API as follows.
General recommendations:• Outlining road maps and master plan according to energy and energy mix, with clear time and period and targets.
The road maps and master plans are binding for all related institutions to develop geothermal energy (the GeothermalRoad Map is attached).
• The role of renewable energies is expected to be enhanced, especially for renewable energies like geothermal that haveachieved economic scale, through an integrated program.
• In response to the energy crisis in Indonesia, there is a need to simplify procedures and bureaucracy in order to accel‑
erate energy conservation and diversification.
• As skyrocketing oil prices in the world market have exceeded USD 50 per barrel, geothermal - renewable energy
utilization needs to be implemented soon, to reduce oil usage for electricity purpose.
• As a developing country, Indonesia has to produce policies on consolidated energy prices so as to increase added value
in the real sectors.
Among the specific or special recommendations are:
• To accelerate the issuing of the Government Regulation to implement Geothermal Law #27/2003 on geothermal
resources, to attract new investment - especially for new or green field sites.
• Honour and resolve all issues related to existing geothermal contracts in Indonesia.
All the above recommendations were submitted to the Minister of Energy and Mineral Resources during the closing
ceremony of the seminar. In his closing remarks, the Indonesian Minister of Energy and Mineral Resources warmly wel‑comed the Seminar and expected that the global oil price hike will drive and create opportunities for renewable energy
enhancement like geothermal energy.

Japan
GRSJ Annual meeting at a local spa resort
Kasumi Yasukawa, AIST, JapanThe Geothermal Research Society of Japan (GRSJ) held its 2005 Annual Meeting at Obama, Nagasaki from 18 to 20
November, 2005, followed by a 2-day excursion to geothermal sites. Approximately 150 members, including five inter‑national participants, participated in the meeting for technical presentations (20 posters, 74 oral presentations), special
lectures and general meeting. Technical sessions cover as wide an area as ever: scientific and engineering studies from
exploration to sustainable operations. Among them, the numberof presentations on geothermal heat pump applications has been
increasing in recent years.
Obama is a traditional beachside spa resort, located in
Shimabara Peninsula, at the foot of Unzen Volcano, the latest
eruption of which occurred in 1990. Although NEDO confirmedoa geothermal reservoir of over 200 C in this area by co-operation
with the local authority as a result of “Geothermal Development
Promotion Surveys” (see IGA News, No. 57, p. 10), further drill‑
ing was interrupted by Nagasaki prefecture due to negative pres‑sure from hot spring owners in Unzen, a neighboring district.
The 2005 meeting was the first GRSJ annual meeting held at
a local spa resort since it was founded in 1978, by collaboration
with the local authority. Two of four organized sessions were open

11Shimabara Peninsula”, recent studies on Unzen Volcano were presented and questions about the location of the magma
chamber and passage of geothermal fluid were discussed enthusiastically. GRSJ hopes these open discussions will help tobreak an “invisible wall” between geothermal society and local hot spring owners. ‘It was very successful! I believe thesecollaborations at Obama really helped the mutual understanding between local residents and geothermal society,’ said
Hiroaki Niitsuma, GRSJ Director, Tohoku Univ., after an informal discussion with hot spring authorities from the region.
Two other organized sessions were titled “Problems and their solutions on steam supply operations for geothermal
power plants” and “Introduction to the technical lecture series on geothermal heat pumps on the GRSJ journal.” The former
session was planned and organized by Japan Geothermal Developers’ Council. Also a special lecture “Eruption of Unzen
Volcano and its scientific drilling” by invited speaker Prof. H. Shimizu, Kyushu Univ. was of interest.
An IGAJ (IGA-Japan) general meeting was also held during the period. Toshihiro (Toshi) Uchida, AIST was selected
as the new representative of IGAJ, succeeding Sachio Ehara, Kyushu Univ.
GRSJ 2006 Annual Meeting is to be held in Ten-ei, Fukushima, another local spa resort, known as a village of renew‑
able energies. Ten-ei is a target area of NEDO’s promotion survey as well.

Philippines
Unocal Philippines now part of Chevron
Edgar P. Sevilla
On August 10, 2005, the stockholders of Unocal Corporation approved the merger agreement between Unocal andChevron Corporation.
The Chevron-Unocal merger paves the way for the creation of a combined company that is now the fourth-largest
publicly traded company in terms of oil and gas production and the third-largest reserve holder among international oil
companies globally.
With the acquisition, Unocal Philippines, Inc. (UPI) officially became a member of the Chevron family. UPI is now
part of the Geothermal and Power group of Chevron’s Indonesia-Asia strategic business unit.
Unocal operates geothermal assets located at Tiwi (232 MW) and Mak-Ban (402 MW) in the Philippines and at
Salak (377 MW) on West Java, Indonesia. Chevron operates geothermal and associated power generation assets at
Darajat (145 MW) also on West Java and a cogeneration facility in North Duri. Consolidation of these geothermal
assets positions Chevron as the leading geothermal energy company in the world with 1,156 MW of installed capacity
in Southeast Asia.
Chevron Corporation is one of the world’s leading energy companies. With more than 53,000 employees, Chevronsubsidiaries conduct business in over 180 countries around the world, producing and transporting crude oil and naturalgas, and refining, marketing and distributing fuels and other energy products. Chevron is based in San Ramon, Calif.

China
Geothermal Serves the Development of Renewable Energy in Tibet
Keyan Zheng, Geothermal China Energy Society (GCES)The Tibet Autonomous Region is located on the southwestern border of China. There is a lack of coal and oil
resources, and previously there were small power plants that used diesel. Yangbajain Geothermal Power Plant started
generation in 1977 and reached a capacity of 25.18 MW in 1991. A big hydropower plant at Yamzho Yumco Lake started
generation in 1997 and reached a capacity of 90 MW in 2004. After that, the Lhasa diesel power plant stopped running.
Therefore, the Central Tibet Grid connecting the main cities of Lhasa (capital city of Tibet), Rikaze etc., basically carries
electricity from renewable energy.
The Qinghai-Tibet railway has just been completed and will start operation this summer. Given the cheap cost ofrailway transportation and the large potential of transportable load, is there a need to transport coal to Tibet to meet thedeveloping local electricity demand? Chinese scientists specializing in energy and renewable energy recently made a
combined proposal. In order to protect the local blue sky, they advocate developing local renewable energy sources tosolve the electric power demand in Tibet, and also solve the problem of local space heating in winter, rather than trans‑
porting coal into Tibet.
There is a load capacity of 24.18 MW in Yangbajain Geothermal Power Plant now, and it has generated 1,880 GWh
of electricity since 1977. It generated 115.4 GWh in 2005. Although its real capacity has decreased to 75 % of design
IGA News, January – March 2006

12
capacity (say about 18.5 MW now) it has run for about 6,000 hours annually in the last 2 years. The Tibetan Bureauof Geological Exploration has explored the Yangbajain deep reservoir and another Yangyi geothermal field. Both hightemperature geothermal fields have the same potential of load capacity of about 30 MW. In addition, several geothermal
fields along the Qinghai-Tibet railway have been surveyed in detail and showed a potential total capacity of 41 MW.
It is predicted that the future demand for power will call for an additional 1,200 MW capacity in 2020. There arerich hydropower resources of about 100 GW capacity that can be developed in Tibet. It is sufficient for the power
demand of the Tibetan main grid, and would also solve the problem of small hydropower supply in decentralized vil‑lages. Hydropower usually runs about 2,000 hours per year, the problem being that there is a lower flow rate in winter.
However, geothermal power generation can fill the peak demand. In addition, for the rather decentralized populationin northwestern Tibet where there is a lack of hydropower, solar and wind energy would be able to meet local power
demand.
Another big energy demand in Tibet is space heating in winter. Only about 10 % of buildings in Lhasa now havespace heating facilities. Most local residents burn cow (yak) dung and firewood for heating. From the point of view ofenergy resources, the huge waste heat from Yangbajain geothermal power plant could be transported after heat exchange
and sent by pipeline to Lhasa. This could provide space heating for 35% of all Lhasa’s buildings. If ground source heatpumps (GSHP) were used on the returned warm water, local groundwater plus GSHP would be able to provide spaceheating for the rest of the buildings and houses in Lhasa and other areas where there is a power supply. For some remoteareas without electricity supply, solar and wind energies can solve local space heating.
Therefore, we can use renewable energy to solve all power and heating demands in Tibet.

OCEANIANew ZealandObituary - Neville Dench 1927-2005
Manfred Hochstein and Richard Bolton
It is with regret that we record the death of Neville
Dench on 17 October 2005 at his home in Auckland, New
Zealand. He was well known in the international geo‑
thermal community for the great contribution he made to
the development of geothermal energy not only in New
Zealand but in many other, mainly developing countries.
The cause of his death was asbestosis, almost certainly
the result of exposure to asbestos during his early careerin geothermal engineering.
Educated at Christ’s College and Canterbury University
College in Christchurch, New Zealand, Neville graduatedBachelor of Engineering (Civil) in 1949. He was electeda Fellow of the Institution of Professional Engineersof New Zealand and became a member of the Instituteof Petroleum Engineers and of the NZ Geothermal
Association.
Shortly after graduating, he joined the New Zealand
Ministry of Works (MoW), transferring to the Wairakei
geothermal project in 1954 at a stage when the investi‑
gations were very much in their infancy. While he wasprimarily responsible for measurements, quality control
and engineering research, the small staff and limited
resources meant that everyone contributed to the solutionof problems as they arose. Thus, Neville laid the foundation on which he built his wide knowledge of the technology
he applied so ably in later years. Among his many contributions at this time was the design of the twin tower silencers
for noise and waste water control, now in wide use overseas as well as in New Zealand. While at Wairakei, he wasawarded the 1963 W.A.Stevenson Award enabling him to visit geothermal installations in the USA, Italy and Iceland
and attend a fluid production course at Texas A & M University.
IGA News No. 63

13Neville transferred to the MoW Head Office in Wellington in 1964 where he was involved with the planning, costing
and assessment of projects within the geothermal programme. During this period he began his long association withgeothermal developments overseas, providing technical support to United Nations Development Programme (UNDP)
and New Zealand Ministry of Foreign Affairs (MFA) geothermal aid projects. In 1971, this involved six weeks in New
York preparing the specification for and assisting in the procurement of the large drilling rig for the UNDP project at El
Tatio in Chile. The following year, at the request of the UNDP, he was granted leave to take up a two year appointment
as drilling engineer with the Olkaria investigation project. Among other things, this gave him valuable experience inthe application of new drilling techniques as well as beginning his long association with Kenya. On his return, as wellas his continued involvement with local geothermal schemes, he visited Indonesia and the Philippines to advise on New
Zealand’s bilateral aid projects then in progress.
In 1975, he was offered and accepted the position of General Manager of Geothermal Energy (N.Z.) Ltd (GENZL).
The firm had just been awarded the contract for the development of the 30 MW(e) pilot plant at Kamojang in Indonesia
and Neville’s first task was to take this through to a successful conclusion. However, as General Manager, he had muchwider responsibilities than Kamojang. Over the next few years, he traveled extensively, promoting GENZL’s interests
in fresh projects as well as providing technical advice on those already underway.
In1984, the Kenyan Power Company asked GENZL to assist with further developments at Olkaria and Eburru, atthe same time asking that Neville be closely involved in the management of the project. He therefore spent the next
two years in Nairobi as Project Director responsible for the overall coordination of these projects. On his return from
Kenya, Neville continued to provide technical support to the GENZL’s work, again requiring much overseas travel. He
retired from GENZL in 1992 as Engineering Director, following which he undertook part time consulting work, finallyretiring in 2004.
Neville contributed much more to geothermal technology than just the hands-on activities he enjoyed so much. His
input as a member of the technical committee which developed the Code of Practice for Deep Geothermal Wells (New
Zealand Standard 2403-1991) was invaluable. This code is still in use both in New Zealand and a number of countries
overseas. Neville also authored or co-authored a wide range of papers and reports on geothermal development, begin‑ning with his paper on silencers given to the 1961 UN Rome Conference on New & Renewable Sources of Energy. As
an indication of the breadth of his geothermal knowledge, a few of the topics he covered include casing string design,
the relationship of law and geothermal development in New Zealand, well measurements and an assessment of thegeothermal resources in the Pacific.
But of possibly even more value to the international geothermal community was the contribution he made to theformation and operation of the Geothermal Institute at the University of Auckland. Following the 1977 decision toestablish the Institute, Neville was asked to join the Founding Committee, where he took an active part in the develop‑
ment of training policies and the syllabus. He became a member of the Board of Studies monitoring the activities of
the Institute and, from the initial course in 1979 until 1998, was a part-time lecturer. Over 500 ex-Diploma students
received the benefit of his block lecture “Introduction to Well Siting and Field Development Strategies.” His wide
experience gave him a deep understanding of the learning and adjustment problems of students from developing­countries which, together with his own ability in transferring his knowledge, made him an excellent lecturer.
Throughout his career, Neville continued to extend his understanding of geothermal technology. He was never reluc‑tant to share the knowledge he gained and had the great ability to do so easily. This, together with his warm interest inother people won him many friends among the international geothermal community.
He will be sadly missed.

WORLD
New EGS Project Handbook (EGS-PMDA) from IEA-GIA Annex III
Mike Mongillo, Secretary, IEA Geothermal Implementing Agreement andThomas Mégel, Alternate Member, GIA Executive Committee and GEOWATT Ltd.
The International Energy Agency Implementing Agreement for a Cooperative Programme on Geothermal Energy
Research and Technology, or Geothermal Implementing Agreement (GIA), provides a flexible framework for exten‑
sive international cooperation in geothermal research and development. Now in its second 5-year term of operation,
the GIA’s major goal is to support and advance the worldwide use of geothermal energy by breaking down barriers to
its development. In this pursuit, the GIA is currently directing its activities to the coordination of members’ national
research programmes for exploration, development and utilization of geothermal resources. As of January 2006,
IGA News, January – March 2006

14
the European Commission (EC) and ten countries: Australia, Germany, Iceland, Italy, Japan, Mexico, New Zealand,
Republic of Korea, Switzerland and the United States, were members.
At present, the GIA participants are working on five broad research areas specified in what are termed “annexes”,
with specific activities of each, defined in “subtasks”. The five current annexes are:
(1) Annex I: Environmental Impacts of Geothermal Energy Development•   To clearly identify possible environmental effects and devise and adopt methods to avoid or minimize their impacts(2) Annex III: Enhanced Geothermal Systems (EGS)•   To investigate new and improved technologies that can be used to artificially stimulate geothermal resources toenable commercial heat extraction(3) Annex IV: Deep Geothermal Resources•   To investigate the commercial development of geothermal resources at depths greater than 3,000 m(4) Annex VII: Advanced Geothermal Drilling Techniques•   To conduct advanced geothermal drilling research and investigate all aspects of well construction, aiming to reducethe costs associated with this essential and expensive part of geothermal exploration, development and utilization(5) Annex VIII: Direct Use of Geothermal Energy•   To improve the implementation, reduce costs and enhance the direct use of geothermal resources for heating andcooling applications
Annex III and the EGS-PMDA
The exploitation of high enthalpy geothermal systems through the use of EGS technologies is one of the most promis‑
ing options for providing sustainable and environmentally acceptable electricity generation and direct use applications.
Recognition of this prospect led the GIA to create Annex III in 1997, to investigate various aspects of EGS. The acqui‑sition and processing of EGS data, and its dissemination in useable form, are fundamental components of the Annex III
work.
For over 30 years, scientific, technical and organizational data and knowledge have accumulated from a successionof long-lived EGS research projects in different countries. In the present period of transition from R&D to commercial
exploitation, it is extremely important that new project teams have access to a synthesis of this data, knowledge andexperience to help ensure a smooth and successful start of their projects. To this end, the first version of an EGS- ProjectManagement Decision Assistant (EGS-PMDA) tool was developed as part of the work in Subtask C of Annex III.
The EGS-PMDA
The EGS-PMDA is a handbook for starting new EGS projects. It provides an information framework for the projectplanning and construction of the first generation of commercial EGS power plants. It assembles an overview of data,
data analyses and experiences (as a reference database of reports and publications, including many abstracts) obtained
from the major EGS projects worldwide since the early 1970s. It also includes an example index of suppliers of services
and equipment, which can be developed specifically for the user’s requirements and local part of the world. A very
important aspect of the EGS-PMDA is that it indicates what and when items of data and information must be obtained
during a project in progress, and where to obtain that data and the currently available experiences.
Specifically, the EGS-PMDA consists of five major sections:(1) Introduction- provides a description of the tasks and targets and the general status of the EGS-PMDA(2) Generic Project- includes the principal milestones within the whole lifecycle of an EGS plant (from the concept
to abandonment phase), and presents the data requirement for each project phase and the first point of need of a specificdata set(3) Index of Suppliers- contains an introduction to the list of suppliers of services and equipment for Western Europe
and an explanation of the information assembled for each of them(4) Collected Experiences- contains the historical, public funded EGS R&D information for Fenton Hill (USA),
Rosemanowes (GB) and Soultz-sous-Forêts (F); with the integration of information for Hijiori (J) now underway(5) Bibliography- includes 2,638 references, ~ 30% with abstracts, for all the terminology variations related to EGS,
such as Hot Dry Rock (DHR), Hot Wet Rock (HWR), Hot Fractured Rock (HFR), Deep Heat Mining (DHM), etc. The
majority of references concern one of the past or present EGS programmes such as Fenton Hill (USA), Rosemanowes(GB), Bad Urach (D), Hijiori and Ogachi (J), Soultz-sous-Forêts (F), Fjaellbacka (S), Deep Heat Mining (CH), Hunter
Valley and Cooper Basin (AUS).
