Details

The Renewables Obligation scheme places an annual obligation on UK electricity suppliers to present to Ofgem (the scheme’s administrator) a specified number of Renewables Obligation Certificates (ROCs) per megawatt hour of electricity supplied to their customers during each obligation period.

The Secretary of State is required to publish the level of the obligation (in ROCs per megawatt hour) 6 months before the start of each obligation period (which runs from April to March).

This note sets out the level of the obligation for the 2025 to 2026 period and explains the underpinning methodology.
