EDF Energy selects Alstom for West Burton and Cottam power retrofit 13 June 2013

The West Burton and Cottam coal-fired power stations are to get Alstom retrofit intermediate pressure (IP) turbines, , designed to improve efficiency and extend the life of the turbines.

Both of the East Midlands power stations are rated at 2,000 MW, and the contract entails replacing the inner cylinder and fitting a new rotor and blades on Cottam 2 and West Burton 1.

Steve Jones, vice president Alstom Power Thermal Services, expects the engineering work to improve the heat rate, reset the life of the major IP turbine components, and ensure lower maintenance costs for the remainder of the turbines' lives.

"We've already successfully carried out retrofits on both low pressure and high pressure turbines at both stations, and look forward to continuing our relationship with EDF as we help make their turbines more efficient and reduce maintenance costs," he says.

Work is due to be completed in spring and summer of 2014, with both turbines being installed during existing planned outage windows.
