‘If you want to have a capacity market and security of supply in the future, you should not model it on an energy system of the past,’ said Fluence’s Elisabeth Giesemann, left. Image: Solar Media.

The upcoming German capacity market must be designed in such a way that enables battery energy storage systems (BESS) to generate revenue, or risk excluding BESS from the mechanism entirely.

This was an opinion expressed by speakers on a panel held during the first day of the Energy Storage Summit at the Battery Show Europe, hosted by Energy-Storage.news publisher Solar Media and co-located with parent company Informa’s The Battery Show Europe, this week in Stuttgart, Germany.

Elisabeth Giesemann, senior policy associate at Fluence, said that the design of capacity market mechanisms is “critical” to the successful integration of BESS into the programme.
