Two UK Solar Farms Approved: Green Hill and Steeple

The government has approved two more large solar farms in England in as many days: Green Hill Solar Farm on 8 October 2026 and the Steeple Renewables Project on 9 October. Together they add roughly 950MW of consented solar plus battery storage. They won't change your roof or your bill directly, but they say a lot about where UK solar is heading, and what that means for homeowners.

What was approved

Green Hill Solar Farm (Northamptonshire and Milton Keynes) was granted development consent on 8 October 2026 by the Department for Energy Security and Net Zero, for up to 500MW of ground-mounted solar with associated energy storage, according to gov.uk. The decision was taken by Baroness Curran on behalf of the Energy Secretary. Developer Island Green Power describes it as 500MW of solar alongside a 500MW battery energy storage system, per Solar Power Portal. The developer's claim that it could meet the annual needs of more than 200,000 homes is a developer estimate rather than an official figure, and other reports quote lower numbers.

Steeple Renewables Project (Nottinghamshire) followed on 9 October. Gov.uk confirms it was granted consent for about 450MW of solar and a roughly 150MW battery system. It sits near the decommissioned West Burton Power Station and will use existing grid infrastructure, Solar Power Portal reports, which also notes local opposition to solar development in the area.

Why a central government decision?

Both are Nationally Significant Infrastructure Projects (NSIPs): generating projects above 100MW are decided by the Secretary of State rather than the local council. The threshold was raised from 50MW to 100MW under the 2025 solar roadmap. Gov.uk notes Green Hill was the 114th energy application out of 182 examined to date, and that the examination finished within the statutory timescale, so this is a well-trodden route rather than an exception.

How it fits the 2030 target

The roadmap aims for 45–47GW of solar by 2030, up from nearly 19GW in May 2025. Provisional DESNZ data reported by pv magazine put deployment at about 21.8GW in January 2026, which leaves a big gap to close. Large farms like these provide the bulk of the megawatts, while rooftop installs supply the volume of households taking part. Our guide on what a solar farm is covers how they differ from home systems.

What it means for homeowners

• No direct effect on your quote or panels. Nothing in either decision changes MCS rules, installer pricing or the Smart Export Guarantee.
• Possible downward pressure on wholesale prices over time. More cheap generation tends to help, as covered in our explainer on the renewables auction and energy bills, but timing and size of any bill effect are uncertain. The farms still need to be built, and neither has a confirmed switch-on date in the sources.
• Batteries matter more. Pairing large solar with storage is designed to soak up midday surplus, the same problem behind negative electricity prices. A home battery plays the same role on a small scale.
• Grid access is the real constraint. Steeple reuses existing West Burton capacity; the Solar Power Portal article says 14 solar plants at various stages will connect there, totalling 1,586MWp. See how this ties into the Great British grid and home solar.

If you'd rather generate your own, rooftop solar on new builds and export payments remain the practical routes for households.

Bottom line: two big consents move the UK a step toward its 2030 solar goal, but the benefit to a household is indirect and slow. If you're weighing panels, decide on your own usage and roof, not on farm approvals.
