Benefits of geothermal energy

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

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

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

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.

Finding a suitable location

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
