Today’s energy markets are still reflecting the cost structures of power plants. Bidding for novel flexible services (like battery storage) is not supported well, mostly because their value comes to a large degree from timing: they can freely shift towards when their service is most valuable. Seita, together with CWI, will test out a new financial product called “energy loans”, which can improve today’s markets. This idea will be prototyped algorithmically, but in parallel Seita will also develop the business case by holding conversations with potential business stakeholders. Funding for this project was granted by NWO Domain Applied and Engineering Sciences.
