The gas-fired station, near Hoddesdon, is about eighteen miles north of London, was built in the early 1990s and fully commissioned in November 1993 and officially opened in April 1994.

Output from the station is enough to meet the daily power needs of nearly a million people - almost the population of Hertfordshire.

The three steam generators supply a single Siemens turbogenerator producing 250 MW at 15.75 kV.
