Swedish energy company Vattenfall has revealed plans to start work to look at the potential for a renewable energy hybrid scheme at Mynydd Lluest y Graig in Wales.
Vattenfall will look at developing a range of technologies, including wind turbines, solar panels and energy storage options at the site, which is located in north Powys between the villages of Talerddig and Llanerfyl.
Previous plans for the site were shelved in 2013 following changes to regulatory regimes in the UK, the company said.
Work will now look afresh at the site and see how the latest developments in technology could be deployed, it added.
Up to 14 turbines at the site would produce enough electricity annually to power 77,500 Welsh homes.
The company also revealed the scheme would include plans for local investment that could bring around £500,000 of funding to the area annually for the lifetime of the project.
Consultation on the plans will start in the Autumn.
Vattenfall project manager for the scheme Jonathan Hewett said: “We’re looking forward to talking to the local community about this renewable energy scheme and seeing what the full potential of the project could be.
“The amount of investment planned through this scheme could be transformative – supporting communities at a grass roots level to reduce their energy bills, invest in the local economy over the long term and build a real benefit from hosting the project.
“Plans are at a very early stage, and later this year we’ll send out information to local homes inviting them to come along and get involved in more detailed plans and designs for the project.”
