The Secretary of State has granted development consent for Beacon Fen Energy Park, a nationally significant solar and battery-storage scheme in Lincolnshire.
The project comprises a 400MW solar photovoltaic generating station with up to 600MVA of Battery Energy Storage System capacity, an on-site substation and an electrical connection to the national grid. The decision was announced by the Planning Inspectorate on 21 August 2026.

What has been approved?
Beacon Fen Energy Park is proposed on land around 2.5km north of Heckington and 6.5km north-east of Sleaford, with the electrical connection running towards Bicker Fen.
The consented project includes:
- a solar photovoltaic generating station with capacity of 400MW
- solar panels up to 4.5 metres in height
- a Battery Energy Storage System of up to 600MVA
- single-stacked BESS units up to 4.5 metres in height
- an on-site substation
- above-ground and below-ground electrical infrastructure at up to 400kV
- security fencing, access and ancillary works
- hedgerow improvements and ecological enhancements
The scale of the generating station means the project falls within the Nationally Significant Infrastructure Project regime rather than an ordinary local planning application.
Why was a Development Consent Order needed?
Large energy infrastructure projects are consented under the Planning Act 2008. Rather than applying to North Kesteven District Council for planning permission under the Town and Country Planning Act 1990, Beacon Fen Energy Park Limited applied to the Planning Inspectorate for a Development Consent Order (DCO).
A DCO is wider than an ordinary planning permission. It can authorise the nationally significant infrastructure itself together with associated development and, where justified, powers over land and other matters required to deliver the project.
The Planning Inspectorate examines the application and makes a recommendation, but the final decision on an energy NSIP is taken by the Secretary of State.
The application and examination timetable
The application was submitted on 8 April 2025 and accepted for examination on 1 May 2025. A six-month examination then allowed local authorities, statutory consultees, landowners, residents and other interested parties to submit evidence and take part in hearings.
The Examining Authority sent its recommendation to the Secretary of State on 22 May 2026. Development consent was granted on 21 August 2026.
The Planning Inspectorate says Beacon Fen was the 112th energy application decided out of 180 applications examined to that point, and that the examination was completed within the statutory Planning Act timetable.
What issues mattered during examination?
The examination record shows the breadth of issues that arise on a scheme of this scale. These included landscape and visual effects, ecology, cultural heritage, traffic and transport, flood risk, agricultural land, cumulative effects with other large solar projects, land rights and the detailed wording of the DCO.
For practitioners, this is an important reminder that the national policy support for renewable energy does not displace site-specific assessment. A solar NSIP still has to demonstrate an acceptable response to local environmental effects, heritage, highways, drainage, land use and construction impacts.
Our guide to Environmental Impact Assessment screening and scoping explains the role environmental assessment plays in major development, although NSIP EIA procedure sits within its own statutory regime.
What does the 400MW figure mean?
The 400MW figure is the generating capacity of the solar photovoltaic project. It should not be confused with the BESS figure, which the consent describes separately as up to 600MVA.
The battery system allows electricity to be stored and released at different times, helping the development interact with the electricity network more flexibly. The consent therefore combines generation, storage, substation infrastructure and a high-voltage grid connection within one nationally significant project.
This is not a precedent that every solar farm will be approved
Beacon Fen is a project-specific DCO decision. The grant of consent does not create an automatic planning route for other solar farms in Lincolnshire or elsewhere.
Future schemes must still be assessed against the policy and legal framework applicable to them, including the relevant National Policy Statements for energy infrastructure, environmental legislation and any site-specific constraints. Smaller solar development may instead fall within the ordinary planning regime or, in limited circumstances, permitted development rights.
For domestic and smaller-scale solar, see our separate guide to planning permission for solar panels.
What happens after the DCO decision?
Granting the DCO does not mean construction can simply start immediately. The Order contains requirements and controls that must be satisfied as the scheme moves towards implementation, alongside other licences and consents that remain necessary.
The developer has previously indicated that construction could begin from 2027, subject to securing development consent and completing the necessary pre-construction steps.
Following a DCO decision, a legal challenge is by way of judicial review rather than a planning appeal. The statutory challenge window is short; the Planning Inspectorate’s guidance identifies a six-week period after the decision. Our guide to judicial review and statutory planning challenges explains the distinction from an ordinary section 78 appeal.
Why Beacon Fen Energy Park matters for planning practice
The decision is another example of the growing interaction between national energy policy and local land-use planning. Large solar projects can cover extensive areas and bring questions about cumulative landscape effects, agricultural land, heritage settings, road construction, substations, cable corridors and compulsory acquisition.
For landowners and local communities, the key practical point is that the DCO process has its own timetable and participation stages. Waiting until the Secretary of State’s decision is too late to raise ordinary planning evidence that should have been put before the Examining Authority.
