Councils are losing 4 in 5 battery storage appeals
England's planning inspectors have decided 67 appeals over standalone battery storage sites. Councils lost 53. In the Green Belt, where refusing feels safest, they lost 23 of 27. The decision letters explain why, in the inspectors' own words - we read all of them.
Councils win the argument - and lose the appeal
Battery storage appeals do not succeed because inspectors find no harm. In the letters, landscape and character findings go the developer's way only 21% of the time, and Green Belt findings only 30%. Inspectors routinely agree with the council that the scheme causes harm.
They allow the appeals anyway. Where need was contested, the finding favoured the development 74% of the time, and the need for storage was the single most common decisive factor in successful appeals (21 of 42 grid-scale wins). The energy-transition balance - grid stability, net zero, a demonstrable unmet need for storage capacity - now outweighs moderate landscape and openness harm almost by default.
These decisions sit with councils by design. A 2020 order removed battery storage from the nationally significant infrastructure regime - the consenting route major power stations take - after the extra time and cost of that route was judged disproportionate for batteries, and because the old 50MW threshold was distorting projects (schemes clustered just beneath it; this dataset still carries the fingerprint in its 49.35MW and 49.9MW schemes). Even the 1.025GW scheme here was decided by a single inspector on an ordinary planning appeal.
The volume is new: 48 of the 67 schemes have been decided since the start of 2025. Refusals are rising, and so are the losses.
The objections that collapse
Across the 52 grid-scale appeals, the share of contested findings that went the developer's way, by issue. The technical objections councils lean on rarely survive scrutiny; only landscape and Green Belt findings usually hold - and even they lose the final balance.
| Issue | Found for the developer | Raised | Rate |
|---|---|---|---|
| Highway and access | 8 | 9 | 89% |
| Flood and drainage | 8 | 9 | 89% |
| Alternative sites | 10 | 12 | 83% |
| Noise | 8 | 10 | 80% |
| Need and benefits | 17 | 23 | 74% |
| Ecology and trees | 10 | 14 | 71% |
| Agricultural land (BMV) | 12 | 18 | 67% |
| Heritage | 8 | 13 | 62% |
| Fire safety | 6 | 10 | 60% |
| Green Belt | 8 | 27 | 30% |
| Landscape and character | 9 | 44 | 21% |
Fire safety deserves a special note, because it dominates local objection campaigns: it was raised as a main issue in only ten appeals and was decisive in just two dismissals. One turned on a submitted layout with battery separation distances below national fire-service guidance; the other on firewater containment above a drinking-water aquifer - and in that case the fire service itself did not object. Both are questions of design detail and site choice, not the principle of battery storage.
Grey belt is rewriting Green Belt refusals
Before December 2024, a Green Belt BESS refusal forced developers through the "very special circumstances" test - winnable, but never certain. The revised NPPF's paragraph 155 grey-belt route changes the question: previously developed or weakly contributing Green Belt land, a demonstrable unmet need, and a sustainable location can now make storage not inappropriate at all.
Thirteen grid-scale decisions engage the grey-belt question, and in ten the route delivered: eight inspectors found the site to be grey belt and the storage not inappropriate at all - Walsall's 49.35MW refusal fell exactly this way in February 2025, and later letters already cite it - and in two more the council conceded the point mid-appeal and withdrew its Green Belt refusal reason. In two others the grey-belt argument failed or did not apply, and the developer won on very special circumstances anyway. Only one, Burnley, ended in dismissal. Overall, BESS appeals that raised Green Belt were allowed 85% of the time - the Green Belt is now a weaker shield for refusing storage than most committees assume.
Six decisions that tell the story
"The relevant criteria contained in Framework paragraph 155 are met and this development does not fall to be considered as inappropriate development in the GB."
"The acknowledged significant weight that must be afforded to the need for the BESS ... far outweighs the low level of less than substantial harm that would be caused to the RPG ... the moderate/minor harm that would be caused to the character of the landscape ... and the temporary loss of 5 hectares of BMV land."
"The benefits amount to material considerations which indicate that the development should be granted planning permission despite the conflict with the development plan as a whole."
"I find the proposal would not involve the undue and permanent loss of a significant amount of BMVAL."
"While other considerations have been advanced including the stated benefits of the scheme ... they would not be sufficient to clearly outweigh the harms to the Green Belt, and the other harms I have identified above."
"Based upon the evidence before the Inquiry I find that it has not been demonstrated that the proposal would not be a significant risk to local residents and the environment."
How we measured this
Source. Decision letters for planning-merits appeals decided by the Planning Inspectorate for England, compiled from the Inspectorate's published decisions. A full-text search for battery-storage terms produced 205 decisive candidate letters; structured reading identified the schemes where a standalone battery energy storage system is the principal development. Solar farms with co-located storage are excluded by definition, costs rulings are removed, and one cross-boundary scheme decided in a single letter under two case references is counted once - leaving 67 standalone schemes, of which 52 are grid-scale (the other 15 are small roadside "micro" battery units, a distinct product class reported separately).
Verification. Every one of the 68 classified decisions was checked by hand against its decision letter - the development description, the operative decision, the determinative issue and the quoted passages. Outcomes are taken from the Inspectorate's case records, not inferred from the text.
Allow rate. The share of decided appeals that were allowed, out of allowed plus dismissed. Withdrawn, invalid and split decisions are excluded. A small number are appeals against non-determination, decided against the council's putative refusal reasons. The all-development baseline (31.1%) is computed from the same corpus on the same basis across 76,077 decisive planning-merits appeals.
The important caveat. An appeal only happens when a developer chooses to challenge a refusal, so this is the success rate among refusals that were appealed - not the share of all battery storage refusals that were wrong. The sample is also young and modest (52 grid-scale schemes; the 95% confidence interval on 80.8% runs from 68% to 89%). What is not in doubt is the direction: battery storage appeals succeed at a multiple of the all-development average.
