Rugeley B Turbine Hall and Gas Turbines

The turbine hall at Rugeley contains two C. A. Parsons generating sets, each have a capacity of 500 MW. The two units were numbered 6 and 7, a continuation of the numbering from the ‘A’ station. Unit 6 was commissioned on 9th January 1970, and Unit 7 later that year on 15th October 1970.

The turbines are Parsons TC2F110 model, consisting of one High Pressure (HP), one Intermediate Pressure (IP) and three Low Pressure (LP) stages. Steam is reheated after the HP stage.

Gas Turbines

In addition to the two steam turbine units, Rugeley also had two gas turbine generators. These were capable of starting the main generator sets without an electricity supply from the National Grid, and could also provide additional capacity as and when needed. The gas turbines were powered by Rolls Royce Olympus engines, and each had a capacity of 25 MW.
