Welcome
Island Green Power has put forward proposals for a new solar and energy storage project in Wiltshire, with associated infrastructure to connect it to the national grid.
The proposed solar park would comprise five Solar PV Sites, together with supporting infrastructure, landscaping and environmental measures. The electricity generated would be exported via an underground cable connection into the existing national electricity transmission system at Melksham Substation.
The project is anticipated as being able to deliver up to 500 megawatts (MW) of renewable electricity through ground-mounted solar photovoltaic (PV) panels. This is enough clean, affordable electricity to power approximately 115,000 homes every year.
Lime Down Solar Park is classed as a Nationally Significant Infrastructure Project (NSIP). Under the Planning Act 2008, projects of this scale require permission through a Development Consent Order (DCO). An application for a DCO was submitted to the Planning Inspectorate, which has now completed its Examination of the proposals. The Secretary of State will make the final decision on whether development consent should be granted.
