EPH bought South Humber Bank power station from Centrica in June 2017.

Phase 1 was completed in April 1997 with 750 MW of power, and entered commercial service in September 1997.

It was initially run by IVO Generation Services, a company owned by Finland's Fortum (Imatran Voima Oy).

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.

The gas turbines used are ABB Alstom GT 13E2 engines which normally produce 165 MW each.

Electricity enters the National Grid via a transformer at 400 kV connected to a single pylon line.

Performance of the power plant is dependent on local air temperature and humidity.
