Vattenfall is exploring a renewable energy project at Mynydd Lluest y Graig in Mid Wales, with plans expected to include a wind farm, and options for other renewable technologies such as solar and storage.

The plans are at a very early stage and consultation will take place in Autumn 2022, with a chance for local people to get involved in developing the project. Vattenfall is keen to develop a project that benefits local farmers, the community and regional businesses, as well as helping to meet Wales’s net zero ambitions.
