Private consumption alliance (PCA) – a worthwhile venture

Would you like an economical and sustainable energy supply for an existing or planned multi-unit property? If so, you can opt for photovoltaics in conjunction with a private consumption alliance (PCA). This model offers many lucrative advantages to both property owners and residents.

PCA – jointly benefiting from solar power

With a PCA, you sell your self-generated solar power to others in your neighbourhood instead of feeding it into the grid. This decentralised energy supply is a win-win situation for everyone:

  • Your investment has a shorter amortisation period and generates a higher return. Through the building’s own energy supply, you can add value to your property.
  • Locally produced solar power is also cheaper than electricity from the grid, as it does not incur any grid costs or levies. Residents benefit from lower electricity costs.
  • Sharing or charging solutions for e-cars or e-bikes can be easily integrated. You are thus paving the way for e-mobility.
  • In addition, the ecological and sustainable power supply from your roof helps to protect the climate significantly.

Frequently asked questions

What is private consumption?

The very word explains what characterises private consumption: According to Art. 16 of the Energy Act (EnA), self-produced energy must either be used by the operator of the system itself and/or be made available to other local consumers directly. The term "private consumption" ceases to apply as soon as the operator's grid connects the system with consumers.

Various consumption scenarios exist:

  • The system produces exactly as much energy as is required over the same period. Additional energy from the grid is not fed in.
  • The system generates more energy than is currently required. This can then either be stored or fed into the grid. Feed-in is remunerated accordingly by the grid operator.
  • The system generates less electricity than is currently needed. In this case, energy can be taken from the storage system or from the grid.

How is energy for private consumption calculated?

With your own photovoltaic system, you basically generate electricity free of charge – at least you don’t need to pay for energy, grid use, grid surcharge and system services. In addition, there are no charges or payments for the community. You pay only for the additional energy you obtain from the grid.

Who purchases the unused solar power?

Where does surplus solar power from your own photovoltaic system go to? You don’t have to worry about that with a PCA: If you don’t want to sell your excess energy on the electricity market, the distribution system operator will accept it from you and pay for it accordingly – in fact it is obliged to do so.

What is unique about a PCA?

The distribution system operator treats a PCA like an individual consumer: Electricity fed from the PCA into the grid counts as a return delivery is metered and remunerated accordingly.

How is a PCA set up?

The following conditions apply when setting up a PCA: The self-produced energy must equal at least 10% of the energy required locally. Several property owners can join forces in the immediate vicinity of the energy-producing system. Or property owners pass on the energy to local tenants, who can, however, choose freely: They can join the private consumption alliance to cover their own needs or remain with their grid operator. At a later date, the tenant can withdraw from the private alliance only if the property owner has failed to adequately fulfil its basic obligation. By the way, this also applies if a tenant changes.

For which type of electricity generation is a PCA possible?

Yes. Private consumption is possible in conjunction with photovoltaics, biomass, and wind installations – regardless of the size of the respective production facility.

Does a PCA also work over several plots of land?

Yes, in every case. The decisive factor is for the self-produced energy to be used locally and not flow through the grid of the distributor. "Locally" is clearly defined as:
• Adjacent plots of land, at least one of which adjoins the one on which the production system is located
• Plots of land separated only by a road, railway line, or watercourse – if the respective property owners have given their consent
