Feed-In Tariffs are separate to the Renewables Obligation (RO). The RO is a regulation which requires licensed electricity suppliers (the companies you buy your electricity from) to ensure that an increasing proportion of the energy they sell comes from renewable sources. The RO mainly supports larger scale centralised renewable generation such as landfill gas, hydropower and offshore wind-farms. The tariffs are intended for people and companies who install renewable generators mainly for their own use.
