Siemens to build combined cycle power plant in the UK


Mar 12, 2007

The Siemens Power Generation Group (PG) will build a turnkey combined cycle power plant in the UK. The purchaser is Marchwood Power Ltd., a 50/50 joint venture of ESBI and Scottish & Southern Energy Plc, who will jointly operate the plant on completion, scheduled for summer of 2009. The contract including a long-term service agreement for the power plant is valued at approximately 500 million euros.

Siemens will build the gas-fired combined cycle power plant with a capacity of 840 megawatts (MW) in the vicinity of Southampton on the English south coast. For the turnkey project, Siemens PG will supply two SGT5-4000F gas turbines, one SST6-5000 steam turbine and three generators. The scope of supply will also include the entire mechanical equipment with two heat-recovery steam generators, the electrical system, the SPPA-T3000 plant control system as well as a 22-km gas pipeline to connect the plant to the national gas transmission network.

“The Marchwood Power plant will be the eighth turnkey power station constructed by Siemens in the UK,” says Klaus Voges, President of Siemens Power Generation. “With a capacity of more than 6000 MW these plants confirm our strong UK power plant presence,” added Voges.

Up to 12,000 MW of new generation capacity could be required in the UK by 2012 to meet the growing demand and to compensate plant retirements. Renewables as well as gas-fired combined cycle power plants are integral parts of the UK’s aim at reducing CO2 emissions. Siemens recently secured an order for the Whitelee Wind Farm, Europe’s largest, to be located south of Glasgow, Scotland.
