Types of PPA contracts



The generator's OZE installation is located in the immediate vicinity of the customer (e. g. on the roof of the building) - electricity generated from OZE  installations is directly supplied to the recipient's internal network.

Near site

The OZE installation is located close to the installation of the energy consumer and the electricity generated from the OZE installation is transmitted via a dedicated transmission line.



The most common version of the PPA assumes that the transmission of electricity from the OZE installations to the recipient's installation is via the transmission network of the network operator.
