CM Forecast Cost

This dataset includes the 24 month forecast of Capacity Market monthly payments. The forecast monthly CM costs are estimated as the Auction Acquired Capacity Obligation (kW) × Adjusted Capacity Cleared Price (£/kW/year) × Monthly Weighting Factor.

The capacity obligation is valued at the relative CM auction Capacity Cleared Price (CCP) and is adjusted for UK Consumer Prices Index (CPI) for T-4 Auctions only. “CPI” means the UK Consumer Prices Index (All Items) published monthly by the Office for National Statistics.
