It is the third Nationally Significant Infrastructure Project (NSIP) – due to its capacity exceeding 100MW – approved in the past week, following the Peartree Hill solar farm and Dean Moor solar project.

The UK energy secretary Ed Miliband has granted a development consent order (DCO) for the 740MW One Earth Solar Farm project.
It is the second-largest solar PV project to receive DCO after the 800MW Springwell Solar plant in April of this year.
Located in Nottinghamshire and Lincolnshire, the project is being developed in partnership between renewables developers Perigus and PS Renewables.
It is also the third Nationally Significant Infrastructure Project (NSIP) – due to its capacity exceeding 100MW – approved in the past week, following the Peartree Hill solar farm and Dean Moor solar project, which received approval in the past few days. It is also the 30^th approved by the government since July 2024.
Ed Miliband, Secretary of State for Energy Security and Net Zero, said: “The only way to have energy security is if we take a pro-growth approach to building more clean energy in Britain. For two years, that is exactly what this Government has done."

The UK government added that the approval for the 740MW One Earth Solar Farm project also comes a few days after it confirmed new planning reforms that would scrap mandatory pre-application consultation requirements for major infrastructure projects. This would help reduce the planning process by up to 12 months and potentially save the industry £1 billion during this Parliament. Passed through the Planning and Infrastructure Act, the changes are expected to come into effect later this month.
Construction of the project is expected to begin in late 2027 and the 740MW solar project will be co-located with a battery energy storage system (BESS) of more than 50MW output.
“Solar power at scale means cheap, clean, homegrown power, insulated from the global instability that has caused energy prices to rocket. Solar farms offer the cheapest power available – and the larger they are, the bigger the economies of scale. Every panel, whether on the ground or on rooftops, is a step towards a better Britain, with an economy safeguarded from the whims of geopolitics,” said Solar Energy UK Chief Executive Chris Hewett.
The future of the development and approval of NSIPs was at the heart of a panel discussion last month at the Clean Power 2030 Summit, with panellists saying that changing political circumstances mean that NSIP approvals and development have become less certain.
Moreover, the approval of the second-largest solar PV project comes in the same week as the government unveiled the solar strike prices for the upcoming Contracts for Difference scheme. The administrative strike price – which is the highest bidding price generators can put into the auction – will remain unchanged at £75/MWh for solar PV in the Allocation Round 8 (AR8).
