But after a renewable energy law that introduced a tariff scheme of EU €0.15 [US $0.23] per kilowatt-hour (kWh) for electricity produced from geothermal sources came into effect that year, a construction boom was sparked and the new power plants are now starting to come online.
The first German geothermal power plant was built in 2003 in Neustadt-Glewe located in northern Germany.
This power plant implements Organic Rankine cycle (ORC) technology and has an electricity output of 230 kW.

This conclusion has regard to the fact that geothermal sources have to be developed sustainably because they can cool out if overused.
