Overview

The purpose of Sellafield Ltd. is to create a clean and safe environment for future generations. Sellafield Ltd. commits to safe, secure, sustainable, site stewardship enabled by the management of a smart, agile, and resilient site. 'Fellside' comprises the Combined Heat and Power Plant (CHPP) and Fellside Boiler Park (FBP); its purpose is to provide a continuous, safe supply of process and welfare steam to the Sellafield nuclear site.

This agreement is the Operations, Maintenance & Management Agreement (OM&M Agreement). The duration of the contract is for an initial term of six years with an option to extend the agreement by up to two further years. The estimated value of the 8-year contract is £128M. The contract commenced on 03/12/2025.
