Belectric’s Energy Buffer Unit At The Alt Daber Solar Project Now Approved To Operate In Germany’s Grid-Balancing Frequency Response Market

Belectric’s 2,000 kWh (kilowatt-hour) containerized battery storage system (the Energy Buffer Unit) at the Alt Daber solar project in Brandenburg, Germany, has been green-lighted to begin operating in the country’s grid-balancing frequency response market, according to recent reports.

For a bit of background here, the 2,000 kWh battery storage system at the Alt Daber power plant was installed in order to provide some backup to the 67.8 megawatt (MW) solar project, to add further revenue streams to the project, and to aid in the stabilization of the wider grid, amongst other things.


With regards to the recent approval to begin providing grid stabilization, the request was granted by the transmission network operator 50 Hertz, thereby approving the storage system to provide 1.3 MW of frequency response.

Probably worth noting here is that Belectric representatives have stated that, owing to the certification process, there was apparently some rethinking of the specifics required for batteries, with some of the testing protocol developed entirely for this installation.

The approval is apparently something of a point of pride for the company, with the comment even being made that “battery storage improves the safety of transmission network operation, even during heavy fluctuations like a generator or interconnector trip.”

I suppose that as far as Germans go, that counts as exuberance.

The approval is certainly interesting, though. I’d imagine that there are many other companies watching the events unfold and considering the possibilities. While the company is apparently pursuing similar plans in the UK, a wider deployment of such an approach is still a bit of an open question.
