  1. Orkuveita Reykjavíkur Sustainable Quality of Life Guðmundur Þóroddsson CEO June 16th 2007

  2. Overview • About the Company • The Geothermal Resource • The Global Perspective • New Innovations and Developments

  3. Orkuveita Reykjavíkur • Orkuveita Reykjavíkur operates distribution networks and provides: • Electricity • To about 58% of the population of Iceland • Hot Water • To about 67% of the population of Iceland • Cold Water • To about 55% of the population of Iceland • Sewage system • To about 53% of the population of Iceland • Orkuveita Reykjavíkur operates in 20 municipalities

  4. Quality systems • Orkuveita Reykjavíkur operates in accordance with: - ISO 9001 - ISO 14001 - OHSAS 18001 - HACCP • The Power Generation is certified as Green by TÜV in Germany

  5. Trends in power generation in Iceland • Shift from electricity generation by hydro to geothermal • New geothermal from less than 100 MW in 1995 to 1000 MW in 2012 • New Geothermal more and more without heat production • More and more of marginal areas being heated by geothermal as fossil fuel becomes more expensive and technology becomes better

  6. Trends in geothermal power generation • Faster development of geothermal • Shorter time from first permit to generation • Bigger initial units – lower cost • Competitive with hydro in Iceland • In the last decade Iceland has been the biggest developer of new geothermal in the world • Big demand for participation in overseas projects • Direct use like district heating spreading

  7. Iceland’s Unique Position • The only place where the ridge reaches surface • The plates drift apart, about 2.5 cm/year • Main effects: • Earthquakes • Volcanic activity • Presence of the geothermal resource Eurasian plate American plate The Atlantic ridge

  8. Exploiting the Geothermal Reservoir Advanced drilling technology Application of properwell- and wellhead equipment Targeting the producing zones Casing off uppermost layers Directional drilling increases success rate in many reservoirs Secure for long-term operation 2000

  11. Geothermal Power Plant – Nesjavellir • Electricity 120 MWe • Hot water 300 MWt • 1640 l/sec (432 gallons/sec) 83°C (181°F) • 23 boreholes • depth 1000 – 2000m • temperatures up to 380°C (716°F)

  12. Hellisheiði Power Plant Project • Combined heat and power plant • Total projected output 300 MW electricity, 400MW thermal • Objective is to meet increasing demand for electricity and hot water in the industrial and domestic sectors of Iceland • Output from first stage, 90 MW of electricity, was delivered to Nordic Aluminium in fall of 2006 • Increased need for hot water in Reykjavik as soon as 2009 • Three additional areas under development, total capacity of 400 MW electricity

  13. The Stern Review and Iceland • The aluminium companies are relatively footloose • Expected global action to mitigate GHG emissions is already acting as a key in driving energy-intensive sectors to countries with renewable energy sources • Prospects of Iceland becoming Europe’s largest aluminium producer

  14. “Exporting Electricity”Estimated Aluminium Production in Iceland by end of each year

  15. The Global Hot-spots

  16. Global Geothermal Electricity • 24 countries generate power from geothermal resources • Costa Rica, France, Iceland, Indonesia, Italy, Kenya, Mexico, Nicaragua, and Russia all show an important increase of relevant power plant installation activities Source: Bertani 2005

  17. Global Geothermal Electricity Source: Bertani 2005

  18. Global Geothermal Direct Use • Capacity 27,824.8 MWt • Use 261,418.0 TJ/yr • Use 72,621.9 GWh/yr • Capacity Factor 0.30 • The countries with the largest installed capacity and annual energy use were the USA, Sweden, China, Iceland and Turkey, accounting for about 66% of the installed capacity and 60% of the annual energy use.

  20. Consciousness of global warming • “Society's dependence on fossil fuels is jeopardizing social and economic progress and our future security. Fortunately, there are many policy and technological options available to avert the impending crisis, but we need increased political will to use them.” Secretary General Ban Ki-moon, June 5 2007 • EC’s 20 by 2020 • Geothermal energy seen as a contributor to the solution • Considerable lack of knowledge and adequate training in harnessing geothermal resources • Utilization of geothermal energy will increase in the near future

  21. CO2Sequestration • Scientific project with University of Iceland, Columbia University (USA), Université Paul Sabatier (Toulouse, France) • Laboratory work • Sequestering CO2 from Hellisheiði plant into boreholes • Combines with carbon-low basaltic rock and crystallizes

  22. Iceland Deep Drilling Project • Scientific project with other Icelandic power companies and NEA. • Drilling of 4-5 km deep hole to reach 400-600°C supercritical hydrous fluid. • Increased power output, perhaps by an order of magnitude. • First hole to be drilled in 2008.
