The largest operational Battery Energy Storage System in The Netherlands Castor is energized and ready to go

We are extremely proud to announce that SemperPower has, after the successful installation by Rolls-Royce, taken over control of its second utility-scale energy storage project Castor.

This project could not have reached its operational phase without the cooperation of our suppliers, capacity off takers as well as financiers. We truly believe that only together we can accelerate the energy transition. To pursue this goal; energy storage systems need to be realized. Therefore, the team of SemperPower is developing its concrete pipeline of 1.4GW, including the realization of our first HV-connected BESS. Stay tuned as the launch of star Antares is in sight!
