In energy and infrastructure documents, Fellside Heat and Power Ltd refers to the corporate entity for the Fellside combined heat and power (
chp) plant adjacent to the Sellafield
site in Cumbria. It is a descriptive
company name, not a term defined in legislation or case law, and is used across contractual, regulatory and property contexts.
The CHP plant generates electricity and steam with an installed capacity of about 170 MW. Approximately 24–26 MW is supplied directly to the Sellafield site, with the balance (circa 142–146 MW) exported to the GB transmission system (National Grid). The plant is located just outside the Sellafield nuclear
licensed site boundary.
Practitioners typically encounter this term in power purchase agreements (PPAs), steam and utilities supply agreements with Sellafield, grid connection and use of system arrangements, balancing and ancillary services documentation, wayleaves/easements, planning consents and environmental permits. Its siting outside the licensed boundary informs allocation of regulatory responsibility (general electricity generation and environmental permitting versus nuclear site licensing obligations).
Usage and meaning are consistent across England & Wales, Scotland, Northern Ireland and Ireland, but the regulatory and market references are those of Great Britain rather than the Single Electricity Market on the island of Ireland.
