Glanford Brigg Power Station
From Wikipedia, the free encyclopedia
Glanford Brigg Power Station is a 240MW gas-fired power station in North Lincolnshire, just south-west of the town of Brigg close to the River Ancholme and B1206 near Scawby Brook.
[edit] History
It was commissioned in December 1993, with construction started in late 1991. It was built just south of a former British Sugar sugar beet factory. Initially, it was owned by Yorkshire Electricity, but operated by (Finnish) Fortum under the name Regional Power Generators Ltd. In 2000, it was bought by Fortum (known as IVO Energy - an abbreviation of Imatran Volma Oy). Since July 2002 when it was bought for £37m, it has been owned by Centrica, with the operating company known as Centrica Brigg Ltd. The station is also known as the Glanford Brigg Generating Station. It falls within the supply area formerly run by Yorkshire Electricity, with distribution currently run by CE Electric UK. It employs thirty six people.
[edit] Specification
It is a natural gas CCGT type power station with four gas turbines, four heat recovery steam generators, and two steam turbines, divided into two modules. It can produce 240MW of base load electricity and 272MW at peak load, from a thermal input of around 515MW. 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% (at constant running); the actual efficiency depends on local weather conditions (temperature and humidity). It is used to fulfil 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 40MWe electrical generator (alternator).
The four chimneys are 70m high. The gas turbines are a General Electric Frame 6 MS6001B type, producing 39.16MW at 31.6% thermal efficiency. They rotate at 5135rpm, connected via a gearbox to the electrical generator revolving at 3000rpm. Exhaust gas reached the steam generator at 541°C. The gas turbine electrical generators are rated at 50.2 MVA, with a terminal voltage of 11kV. The electricity enters the National Grid via a transformer at 132kV.
