I hope you can help me. In our development area, there will be a cold local heating network, where the energy provider supplies the heat pump in the house through deep drilling and a connected ring main network.
We have been considering integrating a photovoltaic system to use the self-generated electricity to power the heat pump. So far, so good! Today we received a letter from the energy provider stating that, for billing reasons, it is not possible to use the self-generated electricity for the heat pump.
Here is the original wording:
“As you have correctly understood, for billing reasons it is not feasible to register self-generated electricity from a photovoltaic system. By feeding it into the system through us, there would additionally be the disadvantage that the full Renewable Energy Act surcharge would apply to all electricity, so the benefit of self-generated electricity would no longer be fully realized.”
Has anyone heard of something similar? Is it really not possible?
If that is the case, a photovoltaic system almost doesn’t make sense anymore. The contract conditions do not state anywhere that self-generated electricity cannot be used for the heat pump.
Thank you very much in advance!

knalltüte25 Feb 2021 21:59Heat sold to third parties generated from self-produced electricity is simply not subject to the Renewable Energy Act! It is heat, not electricity. That’s just how the energy producers operate. Of course, I’m not a lawyer, but if it’s not specified in the contract, how are they supposed to technically prevent that? Are they only now realizing that electricity from homeowners’ photovoltaic systems isn’t good for their business?

The utility provider can prohibit you from powering the heat pump with your own electricity because it would make their system unprofitable. Somehow, the huge costs for building the system need to be recovered. They have to be able to count on at least the electricity for the heat pumps.
However, what they cannot forbid you is to use the photovoltaic electricity for the “normal” household consumption. So, solar panels are definitely worthwhile.
Are you planning to add a battery storage system?

Because there has to be a complete separation between household electricity and heat pump electricity.Similar topics
