Since 1993 the Fellside Combined Heat and Power Plant's (CHPP) primary role is the production of steam to the Sellafield site, the plant has a secondary role in the production of electricity to be exported to the National Grid.

The CHPP is now an ageing fragile facility operating beyond its design life. The site comprises an existing Gas Turbine unit (GT1) and its associated ancillary equipment which have been in operation since 1993 and are expected to continue operating until 2030. The generation of steam is supplemented by 4 boilers in the Fellside Boiler Park. The boilers are expected to be operational until 2045.

The duration of the agreement is six years with an option to extend for up to two years. The current expectation is that the agreement will start mid-2025 and operate to mid-2031 (six years) or mid 2033 (eight years). The scope of the agreement will include a period of combined Gas Turbine and Boiler operations up to 2030 and then boiler only to 2031. There is an opportunity that Gas Turbine and Boiler operations may be extended to 2032.
