Offshore wind farm provides control reserve
The Borkum Riffgrund 1 wind farm operated by Ørsted and Greencoat Renewables PLC is the first German offshore wind farm whose flexibility is used to stabilize the German power grid. Since May 2022, the offshore wind farm has been providing secondary control power for the German electricity grid. The wind farm maintains flexibility and responds to control signals from the e2m virtual power plant, which are requested by the transmission system operator as part of the marketing process.
Energy2market and Ørstedfulfilled the conditions for prequalification ina joint pilot project and played a key role in shaping the project. Approval was granted by the transmission system operator TenneT and the offshore wind farm has since demonstrated in regular operation that short-term grid fluctuations can be balanced out with renewable electricity from offshore wind energy.
Release of the concept for all control areas
In addition to TenneT, the Energy2market prequalification concept on which the project is based also convinced the other three German transmission system operators and was approved for all four control areas.
e2m demonstrates innovative strength
The integration into the German balancing energy market via the virtual power plant of e2m enables Ørsted to market the potential of the offshore wind farm in a system-serving manner and to release additional revenue electricity.
It is also a milestone in the energy transition. Borkum Riffgrund 1 shows that renewables can make a contribution to grid stability and thus turn from a cause of grid fluctuations into a problem solver.
To the point
“Offshore wind power is in no way inferior to electricity from conventional power plants. The power plants at sea not only produce far more electricity than any other renewable energy source. The technology is also competitive in terms of cost. And now offshore wind power is also conquering the area that was previously reserved for conventional energy sources: stabilizing the power grid. Offshore wind power is therefore one of the foundations of the energy transition in Germany, as it contributes to security of supply on many levels.” Jörg Kubitza, Managing Director of Ørsted in Germany
"Not producing inexpensive, sustainable electricity from solar systems in the first place because the framework conditions were not right was not the solution for us. With the storage system, the PV electricity is reliably fed into the grid when it is needed."
Franz Obermayer Junior, project manager for a PV storage combination in Kirchweihdach
