Overview
About the CompanyThe Geothermal ResourceThe Global PerspectiveNew Innovations and Developments
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
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
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
Trends in geothermal power generation
Faster development of geothermalShorter time from first permit to generationBigger initial units – lower costCompetitive with hydro in Iceland In the last decade Iceland has been the biggest
developer of new geothermal in the worldBig demand for participation in overseas projectsDirect use like district heating spreading

Iceland’s Unique Position The only place
where the ridge reaches surface

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

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

The Global Hot-spots
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

Global Geothermal Direct Use
Capacity 27,824.8 MWt Use 261,418.0 TJ/yrUse 72,621.9 GWh/yr Capacity Factor 0.30The 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.

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
CO2 Sequestration 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
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.
