 Contracts from the last three rounds remain in place with the generators receiving the agreed amount from the NFPA and the NFPA effectively taking ownership of the Renewables Obligation Certificate (ROC) which the generator is entitled.Funding for the NFFO was originally generated by the Fossil Fuel Levy, a levy placed on all electricity consumption in the UK.This was collected by Ofgem, which paid it to the Non-Fossil Purchasing Agency, a body created in 1990 by the public electricity suppliers to purchase on the supplier's behalf.
