The Werdohl-Elverlingsen power plant in Elverlingsen near Werdohl is a largely decommissioned medium and peak load power plant belonging to the Mark-E , which will be used as a battery storage power plant from 2018 .
The power plant is located on the Lenne , from which cooling water was obtained. It was fired with natural gas and hard coal . The Werdohl-Elverlingsen power plant has existed since 1912. The last units in operation, which together had a nominal output of 693 megawatts , were built between 1971 and 1982.
blocks
The power plant consists of two hard coal blocks. Unit E3 (186 MW) was built in 1971, unit E4 (301 MW) in 1982. Units E1 and E2 were built in 1975, which are designed as gas and steam turbine systems with 75 MW each and in 1999 and 2003 respectively for the Provision of peak-load electricity and control energy were converted. In the two hard coal blocks, around 4,500 tons of hard coal are converted into electricity every day, which are delivered in block trains by rail . Around 2.2 billion kilowatt hours (2.2 TWh) of electrical energy are generated annually .
The chimney of block E3, which was built in 1971, is 200 meters high, that of block E4, which was built in 1982, is 282 meters high. The cooling tower has a height of 106 meters.
Block E3 is connected to the grid on the 110 kV high-voltage level, and blocks E1 / 2 and E4 are connected to the 220 kV extra-high voltage level in the electricity grid of the operator Enervie AssetNetWork .
Decommissioning and subsequent use
In July 2012 it was announced that the Enervie Group wanted to take the coal-fired unit E3 off the grid in 2014. The reason was the necessary investment of around 20 million euros, which would lead to a "hardly calculable risk". The shutdown took place in April 2014.
In December 2017, the remaining blocks E1 / 2 for provisional and block E4 for final shutdown were reported to the Federal Network Agency. Block E4, which runs on hard coal, was shut down at the end of March 2018. However, a fluidized bed furnace for sewage sludge will continue to be operated.
In 36 years of operation, the 310 MW unit was started almost 2,000 times, had around 180,000 operating hours and was therefore an average of around 5,000 hours per year, i.e. 60% in use.
Battery storage power plant
In June 2018, a battery storage power plant was put into operation on the power plant site, providing primary control power with 8.96 MW and 9.8 MWh of energy from electric car batteries . This is the third large-scale storage system made up of automotive battery systems that Daimler AG and its subsidiary Mercedes-Benz Energy GmbH are connecting to the grid in northern Germany. A total of 1,920 battery modules are bundled as a "living spare parts store" for the third generation of electric smart, built from 2012 to 2015 . Regular use instead of just storage prevents the batteries from being deeply discharged , which would result in a loss of functionality. The response time is in the millisecond range, which means that the storage system can react much faster than conventional power plants. A response time of less than 30 seconds is legally required.
