South Humber Bank Power Station
is a 1260MW
gas-fired power station on South Marsh Road
in North East Lincolnshire north
and the A180
near the South Marsh Road Industrial Estate. It is owned by Centrica
Energy, being run as Centrica SHB Ltd.
Phase 1 was completed in 1997 with 750MW of power, and Phase 2 was completed in January 1999, adding 510MW. It was originally financed by Finland
, the former Midlands Electricity
, Tomen and Alstom. It was initially ran by IVO Generation Services, a company owned by Fortum. Construction started in 1994.
In May 2001, Centrica bought 60% of the power station, and with 40% owned by TOTAL, it was run as South Humber Power Ltd. This meant that the Phase 1 section was run by Centrica, and the Phase 2 part was run by TOTAL. In September 2005, the station was bought outright (100%) by Centrica, costing £150m. The plant was built by Switzerland's ABB.
Cooling water is drawn from the River Humber
. It is a CCGT
type power station using natural gas. Phase 1 consists of three gas turbines
with three heat recovery steam generators
, made by CMI
(Cockerill Maintenance & Ingenierie), and steam turbine
. Phase 2 consists of two gas turbines, two heat recovery steam generators and a steam turbine. It is similar to two CCGTs next-door to each other.
The gas turbines used are ABB Alstom GT 13E2
engines which produce 165MW each. Exhaust gas leaves each turbine at 540C. The engines spin at 3000rpm
. The terminal voltage of the generators is 15.75kV. Electricity enters the National Grid
via a transformer at 400kV. The engines can generate electricity for base load
or for peak load
operations. Performance of the power plant is dependent on local air temperature and humidity.
