Photovoltaic panels solar power generation planning
The existing solar NSIPs regime applies to projects where the proposed generation capacity is more than 50MW in England – estimated by the government to typically consist of around 100,000 to 150,000 solar panels and cover between 125 to 200 acres – and 350MW in Wales. The government is not proposing to change these limits under the revised regime,. The draft revised EN-3 retains the helpful steer given in the initial 2021 proposed reforms that impacts from solar farms should be considered as temporary, though it does recognise that project developers will take different approaches to determining how the project lifetime should be considered in the consenting process. In particular, the update. The draft revised EN-3 sets out factors around site selection for solar farms that will play into NSIP planning decisions. The proposed new policy confirms that development of ground mounted solar arrays is not prohibited on so-called 'best and most versatile' (BMV) agricultural land, but that poorer quality land should be preferred for development.
