Selling solar power

If you produce more electricity than you need, you can sell the surplus energy to us at market price.

We will buy your surplus electricity when

Connecting microgeneration equipment to the network

The local distribution systen operator must always be notified when microgeneration equipment is connected to the network. This ensures electrical safety also in network fault situations.
