Severn

  • Location: Newport, Gwent, Wales  

  • Year commissioned: 2010

  • Construction cost: £600 million

  • Max capacity: 850 MW 

  • Fuel type: Natural gas

  • Technology type: Combined cycle 

  • Interconnection: Uskmouth 275 kV

  • Operating status: Mothballed

Industrial companies and energy suppliers: if you need clean, reliable electricity, Severn and Sutton Bridge combined cycle power plants can be contracted for less than 1.8 pence per kilowatt-hour per year (plus fuel and carbon costs).

​

Due to the UK’s energy market structure, Severn and Sutton Bridge operated at substantial losses for years before ultimately entering administration in June 2020. The plants could no longer afford to provide reliable electricity for the people of the UK and, in August 2020, were forced to enter an indefinite non-operational ("mothball") state.

​

Despite the recent extreme volatility in the UK energy market, the plants have not been contracted and remain in an idle state. Having exited administration in March 2021, Severn and Sutton can be contracted for less than 1.8 pence per kilowatt-hour per year (plus fuel and carbon costs).

  • Can Severn and Sutton be contracted?
    Yes – Severn and Sutton are available to contract in the UK or could even be moved abroad. If you are interested in potentially contracting these low-cost, low-emission plants, please email enquiries@ukpowerplants.co.uk
  • How much would it cost to contract with Severn and Sutton?
    For multiyear contracts, both plants can be contracted for less than 1.8 pence per kilowatt-hour per year (plus fuel and carbon costs).
  • Where are Severn and Sutton located?
    Both plants are located in the UK. More specifically, Severn is located in South Wales, and Sutton is located in Lincolnshire.
  • Were these power plants operating during the September event?
    No – Severn and Sutton have been in a preservation ("mothball") state since August 2020 and are waiting to be economically contracted.
  • How much power can they produce?
    Severn and Sutton each have a maximum capacity of 850 megawatts. Together, these plants are capable of producing 1,700 megawatts of power, meaning they could provide electricity for up to 1.7 million British homes.
  • What fuel do Severn and Sutton run on?
    Both are combined cycle, gas-fired power plants. Natural gas typically costs less and, since it emits up to 50% less CO2, is much cleaner than coal. Moreover, gas-fired generation emits over 75% less NOx than does coal and virtually no SO2 or particulate matter. Severn and Sutton can currently run on up to 15% hydrogen and could eventually be reconfigured to run entirely on hydrogen. In time, Severn and Sutton could be fitted with carbon capture technology to further abate emissions.
  • What is combined cycle?
    Combined cycle power plants, like Severn and Sutton, use both a gas turbine and a steam turbine to produce power. For reference, simple cycle plants use only a gas turbine; per unit of gas, simple cycle plants do not produce as much power as combined cycle plants. Here is a short video that illustrates how combined cycle power plants generally work.
  • Do these plants have carbon capture technology?
    Severn and Sutton could be fitted with carbon capture when the technology is available. Presently, these plants can run on up to 15% hydrogen and could be reconfigured to run on more or even all hydrogen in the future.
  • How can I learn more about Severn’s and Sutton’s technical capabilities?
    Severn was commissioned in 2010 and has two Siemens F-class gas turbines (SGT5-4000F). Sutton was commissioned in 1999 and underwent £45mm of voluntary upgrades in 2016; Sutton has two GE F-class gas turbines (9FAe+).
