Glanford Brigg Power Station, also known as Glanford Brigg Generating Station is a 240 megawatt (MW) gas-fired power station located between the towns of Brigg and the villages of Scawby and Hibaldstow, on the River Ancholme in North Lincolnshire, England.
History
Construction of the power station started in late 1991 and it was opened in December 1993. It was built just south of a former British Sugar sugar beet factory, which is the planned location of Brigg Renewable Energy Plant[1]. Initially, it was owned by Yorkshire Electricity, but operated by a Finnish company, Fortum, under the name Regional Power Generators Ltd. In 2000 it was bought by Fortum, who were then known as IVO Energy. In July 2002 the plant was bought by Centrica for £37 million, with the operating company known as Centrica Brigg Ltd.
Operations
Glanford Brigg power station is a natural gas, combined cycle gas turbine power station with four gas turbines, four heat recovery steam generators, and two steam turbines, divided into two modules. It can produce 240 MW of base load electricity and 272 MW at peak load, from a thermal input of around 515 MW. In the event of interruption of main fuel supply, it can burn diesel instead. It can run at a maximum thermal efficiency of 46.8% when on constant running; the actual efficiency depends on factors in the local weather conditions such as temperature and humidity. It is used to fulfill peak load requirements from the National Grid, as the electricity output can be decreased when demand is less. Each gas turbine and both steam turbines are connected to a 40 MW electrical generator (alternator).
The station's four chimneys are 70 m (230 ft) high. The gas turbines are a General Electric Frame 6 MS6001B type, producing 39.16 MW at 31.6% thermal efficiency. They rotate at 5135 Revolutions per minute (rpm), and are connected via a gearbox to the electrical generator revolving at 3000rpm. Exhaust gas reaches the steam generator at 541°C. The gas turbine electrical generators are rated at 50.2 MVA, with a terminal voltage of 11 kilovolts (kV). The electricity enters the National Grid via a transformer at 132 kV.
The station falls within the supply area formerly ran by Yorkshire Electricity, with distribution currently run by CE Electric UK. The site employs thirty six people.
