Non-Fossil Fuel Obligation
（重定向自NFFO）
The Non-Fossil Fuel Obligation (NFFO) refers to a collection of orders requiring the electricity Distribution Network Operators in England and Wales to purchase electricity from the nuclear power and renewable energy sectors. Similar mechanisms operate in Scotland (the Scottish Renewable Orders under the Scottish Renewables Obligation) and Northern Ireland (the Northern Ireland Non-Fossil Fuel Obligation).
