National Grid ESO has an ambition to be able to operate the GB transmission system carbon-free by 2025. Today, NGESO depends on gas and coal plants for a range of essential ancillary services and takes actions to ensure they are online and able to provide them. To enable zero-carbon operation, zero-carbon technologies require routes to market for all of these services. In many cases, either the current technical specifications or procurement mechanisms prevent zero-carbon generators from participating.
