Industrial batteries in France earn revenue by stabilizing the grid via secondary reserve (aFRR)
As the need for grid flexibility intensifies, French energy storage company Storio Energy is pioneering a new model for decentralized flexibility: behind-the-meter (BTM) industrial battery storage participating in secondary reserve (aFRR). This approach marks a significant shift in how industrial energy storage can contribute to electricity grid stability.
No extremes, except one: Battery trading in a surprisingly steady November
November brought calm to Germany’s power market. As volatility dropped and price spreads narrowed in a well-supplied system, battery revenues became harder to capture. Lennard Wilkening, CEO and co-founder of suena energy, unpacks what this meant for BESS operators and why multi-market coordination proved essential once again.
