BELECTRIC GmbH, key shareholder of Si Power S.A., connected its state-of-the-art, cost-effective battery storage system, the Energy Buffer Unit, at the solar power plant Alt Daber in Brandenburg. It thereby became the first solar power plant in Europe capable of providing operating reserve at high-voltage level comparable to conventional plants.
The innovative lead-acid storage device with a capacity of 2,000 kWh is intended for use in both renewable energy and conventional power plants. The storage device lends greater flexibility to the plant’s service provision and actively stabilizes the energy grid. With its long service life and low cycle costs, BELECTRIC GmbH’s Energy Buffer Unit sets a milestone in the cost-effective and sustainable provision of system services.
“In the future, solar power plants will take over the functions of the most sophisticated network control,” explains Bernhard Beck, CEO of BELECTRIC GmbH. “In conjunction with storage devices, they make an important contribution to the adaptation of the energy supply and grid stability to the requirements of the energy transition.”
Connected to an Energy Buffer Unit “Made in Germany,” solar and wind farms become hybrid plants in which volatile energy sources assume responsibility for the system and contribute to fluctuation compensation. The must-run capacities of conventional power plants can be reduced and replaced by renewable energies equipped with the Energy Buffer Units.
Albrecht Gerber, Minister for Economic Affairs of the State of Brandenburg, declared at the inauguration in Potsdam: “The development of storage technologies is a central prerequisite for the success of the energy transition. Further research is urgently needed. With our Energy Storage Initiative, we seek to encourage the testing of storage technologies.”
