This Order is made under section 32 of the Electricity Act 1989 and imposes an obligation (“the renewables obligation”) on all electricity suppliers, which are licensed under that Act and which supply electricity in Scotland, to supply to customers in Great Britain a specified amount of electricity generated by using renewable sources. As alternatives, in respect of all or part of an electricity supplier’s renewables obligation, an electricity supplier is permitted to provide evidence that other licensed electricity suppliers have supplied electricity generated using renewable sources instead of it, or to make a payment to the Gas and Electricity Markets Authority (“the Authority”). Renewable sources include sources of energy such as wind, water, solar and biomass.
