Storio Energy, specialized in battery energy storage systems for large electricity consumers, has reached a new milestone in France by having its behind-the-meter batteries participate in the aFRR.
The aFRR is used to automatically correct deviations around the target grid frequency of 50 Hz. Until now, batteries providing aFRR services in France were almost exclusively front-of-the-meter, standalone systems connected directly to the transmission grid and equipped with dedicated meters.
“From the very beginning of Storio’s development, we wanted to demonstrate that behind-the-meter batteries can also contribute to the stability of the electricity grid, despite the technical challenges that come with it,” the company said.
One of those challenges is the lack of a dedicated meter, which traditionally prevents grid operators from monitoring BTM battery activity in real time.
