1. 15 MW Geothermal Energy Plant Stephen Mc Loughlin Stephen Devlin Paul O Reilly Mark Flanagan

2. Project Introduction Asked by interested investors to look into viability of investment in renewables - Particulary Geothermal. Market gap for mid sized geothermal solution. Fluctuation of fossil energy prices have made for a volatile market – Goethermal is a safe alternative. Geothermal generation offers a dependable and constant source of revenue – costs are virtually unaffected by prevailing fuel prices. Many geothermal plants have been in operation for years around the globe – Proven Reliability.

3. Presentation Brief All aspects of planning and development of a geothermal plant in Ireland. Planning Permission and Regulation. Budget and Risk. Timeline and project plan. Suitable locations and technical aspects.

5. A Natural form of Energy Heat Generated from decay of minerals Worldwide use – Iceland geezers, thermal baths, New Zealand ect…. 30 Degree temp rise for each KM drilled – Ireland Considered to be sustainable – Takes little heat from overall Not dependant on other energy sources Low emissions and visual impact

6. Choosing A Suitable Location High Temperature Gradient Possibly at a natural fault line (Fracture) Near Transmission or a large Industry Near Supply of Water for Cooling Good Surrounding Infrastructure Reasonably priced Land – Private Local Community impacts and planning

7. Temperature Gradient & Fault Lines

8. Transmission & Available Land and Water

9. Infrastructure

10. Planning and Regulation Five areas are of key importance relating to planning and regulation for this type of project. Pre Planning negotiations Environmental impact statement Planning submissions Planning appeals Public consultations and awareness

11. Pre Planning negotiations Local authority consulted from outset Important first step prior to detailed plan Consulted in all aspects of project Informed of benefits to local community – job creation, clean energy ect… Building relationships are key to this projects success

12. Environmental Impact Statement An EIS is a tool for decision making Lists the pros and cons of any environmentally related project aswell as suggesting alternatives EPA annex 1 development ensures that EIS is mandatory Forms part of the basis of planning Environmental consultants are tasked with EIS

13. Planning submissions Notice placed in local and national papers Application lodged with local council within 2 weeks 2-5 weeks required by council to assess development and allow for objection Further 4 weeks required to allow appeals to be made to Bord Pleanala If no objections within this timeframe final permission is granted

14. Public awareness / consultation Transparent and open approach towards the community Public meetings to hear local views and address concerns Website and phone information service Sponsorship of local evens Avoid poor communication as seen in Corrib pipeline project.

15. Technical aspects of project Kinegad location shows a 90 degree gradient – perfect for binary cycle plant. Expected thermal efficiency of 10 – 13% System is “closed loop” No emissions to atmosphere Takes nothing but heat – water goes back down Expected to generate at 20kV – 15 MW output. Plant is high availability, little downtime once operational – ideal base load generator.

17. Project plan & Timeline

19. Budget & Finance Figures not correct, this is just basic idea for the slide Research, geophysical surveys and test drilling – 4 Million Planning and consultations – 2 million Cost of Transmission Line – 4Million. Cost of plant build – 20 Million Assumed Online Availability Factor = 95% Operation and Maintenance Costs for Plant and Field in cents/kWh = 1c Production prices of about 5-7 cent per KWh once running Electricity Sales Price in cents/kWh = 12 cents Money made from Electricity Sales Price in cents/kWh = 5 cents Average Cost of Production Well = 10 million Average Cost of Injection Well = 10 million Total Capital Costs of the Geothermal Power Project per kW = 100M Total Capital Costs of the Geothermal Power Project per kW – 3000Euro Payback Period = 20 years 30 – 40 according to GT energy

20. Budget & Finance

21. Risk – Barriers High initial capital costs. Planning, permit and legislation – any changes hold up project. Pre build risks – survey errors and research oversight. Geographical risk–Tremors, land subsidence, temperature decline Environmental risk – fines and penalties. Failure of Equipment or injection/production Wells Cost over runs over the life of the project. Very little information of deep geology in Ireland Lack of supporting funding schemes Inappropriate regulatory framework

22. Risk Mitigation Government cost sharing and grant schemes. Large database of research and operation projects. Be informed of up to date technical information and associated risk. Tax incentives. Funding From Sustainable Energy Authority (SEAI) Renewable Energy Feed-In Tariff (REFIT) Having a Power Purchase Agreement in place - help to raise financial support Risk insurance schemes – state sponsored like in Germany – never claimed Guaranteed loan structure.

23. Communication

24. Environmental impact Geo generation is far cleaner then thermal plants such as coal, oil ect…. No negative effect on climate change Plants of this type are low profile – surrounding area not badly affected. The right balance must be struck regarding heat extraction Geothermal water can be toxic – must not be released Steam is only byproduct – large plumes can be seen from this type of plant

25. Benefits of Geothermal Energy Not dependant on climate – Available 24/7 Secure, Reliable and Unlimited Energy Supply Decreases dependency on fossil fuels Price of energy will not change Low Emissions and minimum Visual impact No Air or Water Pollution Only small amount of land required Running costs are very low Helps government to achieve energy and emissions targets
