context_page_description: South Humber Bank Power Station is a 1,365 MW gas-fired power station on South Marsh Road at Stallingborough in North East Lincolnshire north of Healing and the A180 near the South Marsh Road Industrial Estate. It is around two miles east of Immingham, and employs 64 people. The site of SHBPS is around 500 metres by 400 metres in area. It is next door to the Synthomer plant.
  It is owned by EP UK Investments Ltd., which is daughter company of EP Power Europe, which is 100% owned by Czech energy group EPH. EPH bought South Humber Bank power station from Centrica in June 2017.
context_section_description: Cooling water is drawn from the River Humber. It is a CCGT type power station using natural gas.
  Phase 1 consists of three 166 MW gas turbines with three heat recovery steam generators. It was designed and built by a consortium of Cockerill Maintenance & Ingénierie (CMI) and International Combustion, and 255 MW steam turbine.
  Phase 2 consists of two 169 MW gas turbines, two heat recovery steam generators and a 171 MW steam turbine. It is similar to two CCGTs next-door to each other.
  The gas turbines used are ABB Alstom GT 13E2 engines which normally produce 165 MW each. Each gas turbine has 72 EV (conical pre-mix) burners. Exhaust gas leaves each turbine at 540C. The engines spin at 3000 rpm. The gas turbines are each connected to an ABB WY21 TEWAC turbo generator.
  Exhaust gas from each gas turbine passes through an individual CMI heat recovery steam generator (HRSG). For Phase 1 the steam passes through an ABB steam turbine connected to an ABB 50WT hydrogen-cooled turbogenerator. For Phase 2 the steam passes through an ABB steam turbine connected to an ABB WY21 TEWAC (air-water-cooled) turbogenerator. The Phase 1 generator is larger than Phase 2 so needs to be cooled by hydrogen gas.
  The terminal voltage of the generators is 15.75 kV. Electricity enters the National Grid via a transformer at 400 kV connected to a single pylon line. 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. It has a nominal thermal efficiency of 55%, but usually produces 51%.
  In 2009 it produced 8,512 GWh of electricity.
