A £220 million project to introduce the latest combined cycle gas turbine technology has improved efficiency by 50% and drastically reduced emissions to the atmosphere at Peterhead Power Station.
The project, which is the first of its kind in the UK and the country’s largest energy efficiency project, was officially opened last week by His Royal Highness, The Prince Charles, Duke of Rothesay.
Undertaken by Siemens Power Generation, the project was delivered on time and budget. The three 250 MW gas turbines deliver 57% efficiency burning natural gas which compares favourably compares with the average coal fired station efficiency of just over 30%. The concept was designed in-house by Scottish and Southern Engineers who worked with Siemens to deliver the project.
The energy saved has been calculated as equivalent to the average annual domestic use of a city the size of Glasgow. It is of Europe’s most flexible power stations with the ability to burn gas and oil simultaneously and has the capacity to supply 750,000 domestic electricity customers.
The reduction in emissions is equivalent to removing 400,000 cars from the roads – equivalent of nose to tail from Peterhead to Stuttgart – or 6% of Scotland’s emissions from electricity generation.
Scottish and Southern Energy was formed in December 1998 by the merger of Scottish Hydro-Electric and Southern Electric. In August 2000 it acquired Swalec and now has 5 million customers throughout the UK. The company is the UK’s largest generator of renewable energy and it has modern gas fired generation at Keadby in Lincolnsire and Seabank near Bristol in addition to Peterhead.
