Ayrshire Power is to submit plans to build a new multi-fuel power station in Hunterston.
Plans for the project, which will be based on the site of the existing Clydeport coal handling facility, will be submitted to the Scottish Government this week.
It will be the first application for a coal-fired power station to be submitted since environmental laws in the UK were changed.
Under the new regulations, which were introduced last year, coal plants must be fitted with carbon capture technology. The new power station will include Carbon Capture and Storage (CSS) technology. It will also burn both coal and biomass fuels.
Ayrshire Power, which is owned by Peel Energy Ltd, said the new facility would meet the energy need of three million homes.
The plans will be formally submitted to the Scottish Government’s Energy Consents Unit on Monday.
It will then enter a “gate checking” phase while the Government ensures all the information needed for a full assessment of the proposals is included, before being put forward for public consultation.
The company said it would “use highly efficient modern technology with strict emissions control”, with 90% of carbon from the plant being captured, and reducing coal consumption by up to 25%.
It also claimed that the new power station would generate a “significant” number of jobs in the area, with up to 1,600 people being employed during construction and 160 permanent jobs when the power station is running.
