If a PV vendor purchases and installs system on the project site, then the project does not have ‘ownership’ of the renewable system. To obtain LEED credit, the project must get into a ‘power purchase agreement’ where the building buys the electricity from the PV vendor at or lower than market price. The electricity has to flow into the building. The PV vendor may not retain the Renewable Energy Credits (RECs) of the system. If they are retaining the RECs then the LEED project can’t claim credit under EAc2. This is done to avoid any double counting of renewable energy by one plant.
