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 Visual impact
No Air or Water Pollution
Only small amount of land required
Running costs are very low
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 = 50M• Total Capital Costs of the Geothermal Power Project per kW – 3000Euro• Payback Period = 10 – 15 years
Budget & Finance
Risk – Barriers
High initial capital costs.
Environmental risk – fines and penalties.
Planning, permit and legislation – any changes hold up project.
Inappropriate funding schemes
Inappropriate legal framework
Geographical risk–Tremors, land subsidence, temperature decline
Pre build risks – survey errors and research oversight.
Failure of Equipment or injection/production Wells
Cost over runs over the life of the project.
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)
Having a Power Purchase Agreement in place - help to raise financial support
European geothermal fund scheme– GEOFUND
Guaranteed loan structure.
Project plan & Timeline
Project plan & Timeline
Finding 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
Temperature Gradient & Fault Lines
Transmission & Available Land and Water
Infrastructure
