How UK Solar is Setting Records as Springwell Farm Approved
Solar farms across England, Wales and Scotland generated 14.1GW of electricity on 6 April. The output exceeded the previous record of 14GW set in July 2025.
The figure did not hold. Output climbed to 14.4GW on Tuesday afternoon, marking a new national high according to the electricity system operator.
The record coincided with a planning decision that could reshape the UK's energy infrastructure. The government approved the Springwell Solar Farm in Lincolnshire on the same day the second record fell.
The timing also highlighted ongoing concerns about energy security. The UK continues to adapt to pressures created by the ongoing conflict in the Middle East.
Lincolnshire project gets approval
The 800MW site will cover 1,280 hectares of farmland between Lincoln and Sleaford, near Navenby. EDF Power Solutions Limited and Luminous Energy are jointly developing the project.
At maximum capacity, the installation could generate enough electricity to power around 180,000 homes per year. That figure represents approximately half the households in Lincolnshire.
The site will incorporate a battery storage facility. EDF has committed to delivering 12 kilometres of new footpaths and more than 15 kilometres of new hedgerows as part of the environmental package.
The Department for Energy Security and Net Zero granted approval via a Development Consent Order. This planning mechanism applies to nationally significant infrastructure projects.
Matthew Boulton, Director of Storage, Solar and Private Wire at EDF Power Solutions, welcomed the decision.
"I would like to thank everyone who took part in the public examination process and consultations," he says.
"As the project moves forward, we remain committed to working collaboratively with local communities and partners to reduce the impacts of construction while delivering long-term benefits for the region."
Local opposition remains strong
The approval process faced considerable resistance from Lincolnshire residents. Concerns centred on the loss of agricultural land, landscape changes and safety risks associated with the lithium-ion battery storage facility.
Marc Williams, spokesperson for the Springwell Solar Action Group, expressed strong dissatisfaction. He notes he is "disgusted" at the decision and vows to "keep fighting this".
Local Conservative councillor Rob Kendrick spoke against the project at the public inquiry. He calls the outcome "sad news for Lincolnshire and its residents".
"Tourism is worth £1.6bn (US$2bn) to Lincolnshire and that will be impacted," he explains.
Energy Secretary Ed Miliband has made tackling NIMBYism a priority since Labour took office in 2024. The term describes the 'not in my backyard' attitude of locals opposed to infrastructure projects.
"We will take on the blockers, the delayers, the obstructionists, because the clean energy sprint is the economic justice, energy security and national security fight of our time," he notes.
Clean energy approvals accelerate
Springwell marks the 25th large-scale clean energy project approved by the Labour government since it took office in July 2024.
According to the government, those approvals could generate enough electricity to power the equivalent of 12.5 million homes. The figure supports the government's target of a virtually carbon-free grid by 2030.
The electricity system operator is understood to be preparing to run the grid without any gas generation for short periods. This could happen as early as this summer.
Energy Minister Michael Shanks framed the Springwell approval in terms of energy security as well as climate policy.
"We are driving further and faster for clean homegrown power that we control to protect the British people and bring down bills for good," he says.
"It is crucial we learn the lessons of the conflict in the Middle East – solar is one of the cheapest forms of power available and is how we get off the rollercoaster of international fossil fuel markets and secure our own energy independence."
Springwell is currently expected to begin exporting electricity to the national grid in 2029.
