Spalding Power Station is an 860MW gas-fired power station one mile north of Spalding on West Marsh Road close to the River Welland. The current site provides enough electricity for one million households.
The power station, known as the Spalding Energy Facility, is sited on a former sugar beet site of British Sugar. It was first proposed in October 1996 and given approval by the DTI in November 2000. It is run by the Spalding Energy Company Ltd, a subsidiary of Intergen. Intergen is jointly owned by the Ontario Teachers' Pension Plan and China Huaneng Group.
The electricity is supplied to Centrica under a 17 year deal agreed on 22 May 2002; Centrica originally had 50% of the equity in the project in December 1999, and they supply the gas. It was the first power station to be project financed under the New Electricity Trading Arrangements in England and Wales, and funded by Barclays Capital.
Construction began in March 2002. It opened in October 2004 at a cost of £425 million.
A development of the power station will be constructed from 2011, to begin operation in 2014, at a cost of £500 million. The expansion is timed to coincide with withdrawal of older UK power stations. The combined plant will have a capacity of around 1800MW.
It is powered by natural gas in a combined cycle (CCGT) plant. It features two General Electric 9FA+e gas turbines with two VOGT-NEM heat recovery steam generators and one Hitachi steam turbine. VOGT Power International is based in Louisville, Kentucky, and is owned by Babcock Power Inc. It uses two GE air-cooled turbo generators, rated at 296 MVA with a terminal voltage of 15.5 kV on each of the gas turbines. On the three-stage steam turbine is a Hitachi hydrogen-cooled turbogenerator, with a rating of 430 MVA and a terminal voltage of 24 kV. Actual power output depends on atmospheric conditions, such as temperature and humidity. 360MW comes from the steam turbine generator, and 265MW from each of the gas turbine generators.
