British utility Scottish Power, owned by Iberdrola, plans to build a 950 combined-cycle gas turbine (CCGT) power plant near Bristol.
According to Reuters, the first stage of the consultation process for the plant, known as Avon, is scheduled to begin this month. Scottish Power has not made a decision on when to bring the new plant online.
"A number of power stations in the UK are due to cease operating from 2015 onwards and, in order to guarantee long-term security of electricity supplies, it is important that energy companies continue to look at the best options for replacing the electricity generation that will be lost," said Richard Escott, head of project development at Scottish Power.
Britain's Infrastructure Planning Commission (IPC), which manages planning permits for large-scale energy and infrastructure projects, said it had received pre-application information from Scottish Power for a 950 MW gas fired power station near Bristol.
The IPC expects to receive the project's full planning application on October 3, it said on its website. The body has 28 days following the submission to decide whether to approve the project.
Meanwhile, Scottish and Southern Energy, another one of Britain's largest energy companies, is set to sign later this year a 10-year gas supply deal with Norway's Statoil, the UK company said on Monday.
The Norwegian oil and gas giant will send 500m cubic metres (mcm) of gas annually to SSE's Peterhead power station via Scotland's St Fergus terminal.
Gas supply is expected to start in the fourth quarter of 2012 and the piped gas can be diverted to other SSE facilities if Peterhead power station undergoes maintenance or repair work. SSE also plans to develop a carbon-capture and storage (CCS) project at its Peterhead power plant.
