LCCC

LCCC is a government-owned company that manages two key schemes supporting the UK's electricity system: Contracts for Difference (supporting renewable energy) and the Capacity Market (ensuring enough generation capacity exists).

LCCC responsibilities:

• Administering CfD contracts with renewable generators
• Calculating quarterly Interim Levy Rates (ILR) for CfD
• Managing Capacity Market payments to providers
• Calculating Capacity Market supplier obligations
• Publishing levy rates and methodologies

CfD administration: When renewable generators produce electricity, LCCC pays them the difference between the "strike price" (the guaranteed price) and the market reference price. When market prices exceed strike prices, generators pay money back. LCCC calculates the net cost and passes this to suppliers via the quarterly levy.

Capacity Market administration: LCCC also acts as the counterparty for Capacity Market agreements, making payments to providers who commit to being available during system stress events.

Why LCCC matters for bill validation: EnergyCode uses LCCC's published levy rates to validate CfD charges on your bill. If your supplier is charging a different rate than the published LCCC Interim Levy Rate for that quarter, that's an error.
