German optimisers and tolling providers - and where to find them
As an asset owner, you need to choose the right optimiser for your battery to perform in the market. Germany is one of Europe's most established battery storage markets, with a large and growing operational fleet and a well-developed set of revenue streams spanning frequency markets such as FCR and aFRR, the day-ahead energy market, and deep and liquid intraday trading. As competition in ancillaries has intensified and the revenue stack has evolved, the choice of optimiser - and the sophistication of their cross-market strategy - will shape how much of that value an asset actually captures.
At Modo Energy, we have prepared a list of market participants offering third-party representation and optimisation services for battery storage in Germany. Below, optimisers and toll offtakers are listed in two separate lists, both ordered alphabetically.
