Costain Siemens has been selected to deliver high voltage power supply systems for the HS2 project throughout the 225km route between Birmingham and London.
The contract, yet to be signed, is expected to be worth in the region of £300m to the joint venture, with optional contract extensions. There is a separate maintenance contract following the design and build phase. The maintenance contract will operate for seven years and is valued at £32m for the joint venture.
This contract is in addition to the £400m HS2 rail systems contract that Costain, operating alone, secured earlier this month. As previously reported, Costain is the sole supplier for tunnel and lineside mechanical and electrical systems for HS2. That contract will start in the first quarter of 2025 for a seven-year period, with the option for additional contract extensions.
Costain chief executive Alex Vaughan said: “This contract marks the start of a new partnership with Siemens Mobility and its team of experts who share our values and ambitions. Providing a safe, reliable power system will be critical to the success of HS2, with rail electrification a crucial part of the UK’s decarbonisation plans.”
