Proposals to build one of the largest solar power farms in Wales, rated at nearly 50 megawatts, at a 140-hectare site at Llanwern in the Gwent Levels have been submitted to the devolved administration as a development of national significance.  The 345 acre project, just south of the former Llanwern steelworks, could power the equivalent of 15,000 homes for 30 years.  The project includes battery storage.
