Controversial plans for the first coal-fired power station to be built since the 1970s have been formally lodged.
The proposal to develop at Hunterston in Ayrshire, first submitted in March, has been checked by officials and can now be opened for public comment and consideration by the Scottish Government.
MSPs have already signalled their opposition to the plan, which environment groups also oppose. In March, MSPs backed the Green party in a 66-26 vote urging ministers to reject the application.
The vote added to concerns that the carbon capture and storage (CCS) technology, which removes CO2 emissions and pipes the gas underground, is not ready on a commercial scale.
Ministers did not vote on the issue following advice that they cannot air opinions while the application is being considered.
Applicants Ayrshire Power said the plant could meet the energy needs of three million homes and create 160 jobs, with 1,600 people working at the peak of construction.
It is the first application in the UK since rules forcing all new plants to be fitted with CCS technology were introduced last year.
Project director Muir Miller said: “We are pleased that our application has now progressed to the next stage of the planning process.
“We believe our proposal supports the UK and Scottish governments’ commitment to leading the way in developing CCS to assist in de-carbonising the UK’s electricity sector by 2030.”
The development is earmarked for a site between the existing Clydeport coal handling depot at the Hunterston terminal and Hunterston B nuclear power plant. It would burn coal and “biomass” fuel with “strict emissions control”, the firm said.
