Alstom has agreed a deal to upgrade nine gas turbines in UK power stations owned by the energy firm RWE Generation.

The engineers claims the upgrades at the 2,200 MW Pembroke and 1,650 MW Staythorpe sites will increase the performance and efficiency of the GT26 turbines they use.

The agreement also includes a maintenance programme for RWE Generation’s fleet of GT26 turbines across Europe.

Michael Rechsteiner, Senior Vice President for Alstom’s Thermal Services business said the upgrade would reduce maintenance hours over the life of the plant.
