The startup offers green electricity at a variable rate. In return, Ostrom buys electricity like many other suppliers, but passes it on to customers at cost. Earned is a fee of six euros per month.

We adjust prices – if necessary – and also go back down again. That motivates people to use electricity efficiently and save costs,” according to founder Martensen, especially when electricity is expensive at the moment.
