RCP: the operational principle
The RCP (or ZEV) allows a building to consume its solar production locally before withdraw the balance from the network. Concretely, a main counter measures exchanges with the DSO, then an internal distribution allocates consumption to each batch.
Why it is economically interesting
Electricity self-consumed locally avoids part of the purchasing costs at the standard rate of the network. On well-sized buildings, this improves the profitability of the installation and reduces the bill for occupants, provided they have a clear and billing method. serious energy management.
Extension at neighborhood level
Local energy community models aim to share production beyond a single building. This development is promising but remains regulated: technical connection rules, GRD conditions, and legal compliance must be validated before launch.
