Plans for a renewable energy park in Neath Port Talbot have been announced which could power 40,000 households.
EDF Renewables UK has said it is looking to build Hirfynydd Renewable Energy Park near Crynant and Seven Sisters with an installed capacity of 100 MW.
The subsidiary of EDF Group will install a range of technologies at the site, including a wind farm of up to seven turbines, a solar farm and battery storage.
The company says having a range of renewable technologies increases the amount of energy that can be generated at the site in different weather conditions - with onshore wind and solar the most cost effective ways of generating electricity.
Battery storage on site will also allow surplus energy to be stored for grid balancing services.
Principal project development manager Simon Morgan said: "Hirfynydd would make a positive contribution to our efforts to tackle climate change and at a time of global uncertainty over energy supply and costs, renewable energy projects are vital to dealing with these challenges."
He added: "We are pleased to be developing Hirfynydd in partnership with three local farming families and we will work with the community to ensure that the project can deliver local benefits, such as a community fund and local ownership.”
EDF Renewables UK says it has been carrying out early ecological and other feasibility studies.
In September, the organisation's project team will hold events to share information about the proposed plans and obtain early feedback from locals living in Crynant and Seven Sisters in the Dulais Valley.
They will also hold public information days for communities near the proposed wind farm site for local people to gain a better understanding of the proposals and provide initial feedback.
Interactive 3D visual software modelling will be available at the exhibition so that residents can get an impression of what the proposed development might look like from different angles and viewpoints.
EDF Renewables UK will also be submitting a scoping report to Planning and Environmental Decisions Wales, with a final decision being taken by the Welsh Government.
It hopes to submit a planning application for the energy park towards the end of 2023.
An application to erect a meteorological mast – to collect wind speed data – will also be submitted to Neath Port Talbot County Council.
EDF Renewables UK has an operating portfolio of 38 renewable energy sites including battery, onshore and offshore wind (together totalling 1 GW), but it has 5 GW worth of projects in planning and development, including wind, battery and solar PV.
