A power plant at Kiel in Germany is to take a delivery of 20 Jenbacher J920 Flextra gas engines with a power output of 190 MW, which represents the largest sale in the history of the Jenbacher company, according to GE.
The gas-fired power plant is to serve a district heating system in Kiel. General contractor Kraftanlagen München (KAM) will build the plant on behalf of municipal utility Stadtwerke Kiel. The new power plant will replace the existing coal-fired community power plant.
The company added that the marketing of balancing energy and the integration of an electrode boiler (power-to-heat) during periods of low electricity prices provide a flexible and economical solution. This ensures not only the regional supply, but also guarantees operational cost-effectiveness. Compared with the previous coal-fired power plant, CO2 emissions are reduced from 1.8 million tonnes to approximately 540 000 tonnes.
“The new gas-fired thermal power plant in Kiel is a groundbreaking example for the successful realization of the energy transition plan by employing highly efficient combined heat and power generation,” said Gerrit Koll, business unit leader, energy and power plant technology at KAM.
The greatest possible flexibility was a primary requirement of the new Stadtwerke Kiel plant, said GE. Due to the high proportion of wind-generated electricity in the regional grid, the power plant has to be able to feed full power into the local electrical grid within a short period in order to offset the volatility of the wind level, thus ensuring stability of the grid. The Jenbacher J920 FleXtra gas engines can be called up to their full capacity in just a few minutes.
The initial project involves the planning and construction of the pump house to connect to the district heating system, the electrode boiler and heat storage as well as scheduling and obtaining operating approval for the entire system, including gas engines. The second phase of the project, including construction of the gas engine power plant, is scheduled to be underway starting in May 2016.
