Lease storage capacity at SemperPower and take the load off in large-scale sustainable energy storage.

SemperPower provides capacity in large batteries for sustainable energy storage with transparent pricing and a proven capacity offtake contract structure. Plus this guarantee: green electricity always and everywhere. But our approach goes further.


We take the load off by developing and managing these energy storage systems entirely ourselves. The best technology, risk management, regulations, permits, guarantees, insurance, maintenance and other red tape can all be left to our specialists. We ensure that it works, and take away all the concerns. We call this Storage-as-a-Service (SaaS). An attractive proposition for grid operators, sustainable energy traders and portfolio holders, wind and solar farm developers and industrial consumers. 

To purchase an energy storage system or lease capacity

To purchase your own battery with a service life of 20 years, or to lease a piece of energy storage? You only lease capacity you need, and we take care of the rest. From the best technical configuration to the energy storage control system, with 24/7 service from a single provider.

Without risk or investment, our energy storage systems contribute to the challenges facing the energy sector. As an operational partner, you gain additional return from the MWh generated.

Battery dependability is front and centre

We work transparently, selecting the best technology every time. That isn’t necessarily the same supplier every time - because we believe quality and safety are of the utmost importance, we assess this from scratch with every new energy storage project. Each and every partner is a specialist in their field, and all boast a proven track record.
