De-rated capacity margin
Planning our electric future: a White Paper for secure, affordable and low-carbon electricity, Glossary, published by the Department of Energy & Climate Change on 14 July 2011, defines the de-rated capacity margin as: ‘The capacity margin adjusted to take account of the availability of plant, specific to each type of generation technology. It reflects the expected proportion of a source of electricity which is likely to be technically available to generate (even though a company may choose not to utilise this capacity for commercial reasons).’
Where the capacity margin is: ‘The difference between peak demand and installed capacity, adjusted for probable availability at peak.’
