Severn Power station is situated at Uskmouth near Newport in South Wales and uses gas to produce electricity which is feed into the national grid. The power station consists of two identical units and began generating power commercially on 9th November 2010, when the first of its twin gas and steam turbines was brought on-line. The second unit followed 26 November 2010.

The new energy-efficient gas-fired power station has the capacity to generate up to 824 MW net of electricity. This is enough to meet the average power needs of around 1.5 million homes or capable of meeting more than 1 per cent of the UK peak electricity demand on its own

Severn Power Station uses combined cycle gas turbine (CCGT) technology, which makes it one of the most advanced power stations of its class. Using some of the most modern energy generating equipment available, Severn Power Station has a thermal efficiency of approximately 58 %, making it one of the most efficient natural gas-fired power stations of its type in the UK. This is a big improvement compared to the performance of older style power stations. As a result, it produces far less emissions per unit of energy generated.
