A South Derbyshire power station may be brought back into operation after the site was derelict for 10 years.
RWE npower is looking at turning the empty site of the former coal-operated power station at Willington into a gas-fired plant.
The firm said plans were at an early stage and it would consider possible impacts on the area before proceeding.
A planning application for a residential development at the site was turned down in January.
Mike Peel, RWE npower project manager said: "A number of existing power stations are expected to close in coming years and, as a result, the UK could face a major shortfall in power supply.
"A new power station at Willington would help plug this energy gap."
The site has a connection to the National Grid and access to cooling water.
Mark Todd MP said: "Some parts of the site, which stretches down to the Trent, are clearly undevelopable and should be set aside for community use and open space.
"I look forward to seeing detailed proposals as will, I am certain, local people who have been concerned at the long dereliction of the site."
