If solar PV is allowed to bid into a future Capacity Market it will be derated to less than two per cent of headline output, according to a consultation published by the EMR Delivery Body.
That means it would receive less than two per cent of the per kilowatt clearing price.
Under the proposals, onshore would be derated to under 9 per cent, offshore wind to under 15 per cent and short duration storage (half an hour or less) to between 15 and 17 per cent.
The Delivery Body said those calculations were based on long term averages using NASA MERRA and other datasets to look at 12 years of actual conditions and output from renewables.
