Siima Solution GmbH (Stromkonto)

Decentralization, empowered prosumers, and fragmented markets are reshaping how energy is produced, shared, and consumed. We are building the first energy wallet - combining data, trading, flexibility, and services in one account. Turning electricity into a tradable, usable asset.
With Stromkonto®, this vision becomes reality. It allows prosumers to store, share, and trade their energy – all in one account. For the first time, you can use 100% of your solar energy. In the evening. In winter. Or wherever you need it – for example when charging your electric car on the go.
