Battery storage on a capacity market
In Germany – but not only there – there is a heated debate about the pros and cons of a capacity market. The German Renewable Energy Association is against it, and recently the German New Energy Industry Association, the DIHK and the EEX energy exchange have also taken a clear stance: Germany does not need a “power plant subsidy program.” In this article, four experts explain why battery storage can also play an important role in a capacity market and make recommendations on how the design of the market can help avoid mismanagement, wrong incentives and unnecessary costs.
