E.ON SE is planning to install several small-scale power plants at its German geothermal facility in Kirchweidach, Bavaria, to enable the site to produce green electricity.
The company plans to build total generation capacity of around 6 MW and will operate the plant for 15 years, it said Aug. 19.
The plant produces heat for the local district heating network and a major customer that grows vegetables, and E.ON said it is a challenge to expand it in a way that carbon-free baseload electricity can be generated economically.
In order to do this, the utility is using so-called ORC modules from its partner Orcan Energy AG, whose waste heat recovery technology converts heat into electricity in an efficient manner.
The construction will take place in two phases, with a capacity of 1 MW to be installed in the first phase of the project, which will involve an investment of €7.5 million.
Upon completion at the end of 2021, the construction of a large-scale ORC plant and a combined heat and power plant is planned.
"In cooperation with E.ON, we can fully exploit the heat potential of our geothermal plant and generate green electricity economically," said Wolfgang Hageleit, managing director of the plant's operating company, FG Geothermie.
