Cold reserve refers to a generating unit which has been decommissioned but has a valid operating permit and can be used to the full extent from a technical perspective and, which is, however, not operated for other reasons (e.g. long-term fuel shortage, too high fuel prices, too low exchange prices). Recommissioning requires the preservation measures to be removed and is, hence, not possible right away. For this reason, the output which is part of the preserved cold reserve is not directly usable for the market either.
