The procurement involves a single supplier framework for comprehensive power equipment renewal and upgrading. The project is critical for enhancing system resilience and mitigating service-impacting failures, with a planned contract period starting from 29th September 2025 through to 28th September 2035.

Additionally, engaging in this project with Transport for London can enhance a company's portfolio, given the prestige of the client's public sector stature and the large scope of work involved.

## Notice

Single supplier framework for the design, commission and installation of substation power equipment. The Direct Current High Speed Circuit Breakers (DCHSCBs) that comprise the DC switchboard in Love Lane, Jubilee Bridge, Mitcham Junction, Woodside, Parkway, Beckenham Junction, Sandilands, Belgrave Walk, Dundonald Road, East Croydon Substations were installed in the late 1990's and these circuit breakers are nearing the end of their serviceable life. By renewing and upgrading the DC switchboard at these 10 Substations the project will improve the system resilience and availability by introducing new equipment. This will in turn reduce the risk of service impacting failures and improve the whole life costs for these assets.
