Drilling begins in the UK's first deep geothermal power plant in Cornwall

Drilling will begin in Britain's first deep geothermal power plant in Cornwall, where "hot rocks" could supply 3,000 homes

  • The aim of the project is to show the potential of geothermal energy
  • Two wells will be drilled through granite boulders, the deepest will reach 2.8 miles
  • The plant could have the potential to power 3,000 households

Drilling will commence this week at what is possibly Britain's first geothermal power plant in Cornwall.

Near St Day, two wells will be drilled through hot granite boulders, the deepest of which will reach 4.5 miles and power 3,000 homes.

According to Geothermal Engineering, the potential of geothermal energy to generate electricity and renewable heat in the UK will be demonstrated.

The United Downs Industrial Estate plant is expected to have the potential to deliver up to 3 megawatts of electricity.

Once the site drilling is complete, water will be pumped from the deep well at a temperature of approximately 190 ° C (374 ° F).

This water is conveyed through a heat exchanger on the surface and injected again into the soil to absorb more heat from the rock in a continuous cycle.

The recovered heat is converted into electricity and fed into the national grid.

Geothermal technology is referred to as a "continuous" energy source because it does not suffer from peaks and valleys of other sustainable energy sources.

The developers hope that the technology used in the plant could be used at other sites in Cornwall and Devon where hot rocks are located (pictured).

Similar plants were developed in Insheim and Landau in Germany.

Dr. Geothermal Engineering General Manager Ryan Law said geothermal resources could cover up to 20 percent of UK electricity and heat energy needs.

He said, "It's incredibly exciting to see this forward-looking project getting off the ground with what we hope will be the launch of many similar initiatives across the UK."

The £ 18m ($ 24m) project worth £ 10.6m ($ 13.8m) from the European Regional Development Fund and £ 2.4m from the Cornwall Council (3, US $ 1 million) and 5 million GBP from private investors.

Cut your energy costs

If you've been with the same provider for some time, you could cut energy costs by hundreds.

Millions of households use the most expensive non-contractual offers from their provider. But if you switch to a better deal, you can immediately save money.

According to This is Money and MailOnline's expert partner service, energyhelpline, every tenth family could lower their annual bi-component use bill by £ 537 a year by phasing out the bill.
