Prior to the suspension, the station had a generating capacity of 1875 megawatts (MW), making it the largest of any CCGT power station in Europe. The station could meet almost 3% of the electricity demand for England, Wales and Scotland. Opened in 1993, the station was initially operated by Enron

During maintenance closure in August 2001, an explosion near one of the power station's transformers killed three workers and injured another man.

After Enron's bankruptcy in 2002, the power station was sold to a management buyout. It was owned by Teesside Power Limited (TPL) and operated on behalf of its owners by PX Limited.

Plans for a £500 million upgrade of the station were granted planning permission in 2008. This upgrade would consist of replacing the existing generating equipment with four 300 MW gas turbines and two 340 MW steam turbines. This would retain the power station's current capacity. However with no work having begun by 2010, a five year extension to the permission was granted in April 2010.

 in 2010, the ownership of the site was shifted to the latter company.

On 1 April 2011, GDF surrendered 1,830 MW of transmission entry capacity (TEC) of the station and ceased operations of the CCGT element of the plant leaving the Open Cycle gas turbine as the only available machine, leaving the station with an operating capacity of 45 MW. This was due to the low cost of energy imports and a weak market in the UK, resulting in a need to save on operating costs. It is unknown how long the power station will be out of operation for and around 100 workers may lose their jobs due to the mothballing. International Power's lack of clarity over the workers' jobs has been condemned by unions, with Unite the Union

Specifications

With a total generating capacity of 1,875 MW, the station has the largest generating capacity of any CCGT power station in Europe, although it had been the largest in the world at the time of opening. It generates enough electricity to provide 3% of England, Wales and Scotland's combined power needs. The electricity is produced by a number of generators. These are: eight 152 MW Mitsubishi Heavy Industries
