ABOUT US

The Spalding Energy plant, a 860 MW power station, has a long term energy tolling agreement with the UK gas and power company Centrica. The plant provides it power to Centrica’s domestic and industrial customers via the UK national Grid. The Spalding plant employs some of the most technically advanced equipment in the power industry and combined with the use of the most energy efficient fuel (natural gas) the Oxides of nitrogen (Nox) are approximately 1% of a those emitted by a conventional coal plant with sulphur dioxide (SO2) emissions approaching zero. In addition the facility generates less than half the carbon Dioxide (CO2) of a coal station making the plant a positive force in the global effort to reduce levels of green house gases.
