The UK's battery energy storage (BESS) sector is one of the fastest-moving segments in the national planning pipeline. Developers, investors, grid consultants and insurers all need to know: which projects are new, which changed status, and which changed ownership — without manually re-reading a quarterly CSV export every time.
The official source, the Renewable Energy Planning Database (REPD), is a flat, unfiltered snapshot. It tells you everything currently in the pipeline, but nothing about what actually changed since your last check. This article explains how to turn that static register into a real change-detection feed.
Why a flat REPD export isn't enough
REPD is published quarterly by the UK Department for Energy Security and Net Zero, under the Open Government Licence. It's comprehensive — but as a raw export it has three practical limitations:
- It's a full snapshot every time: there's no built-in way to see only what changed since last quarter.
- Battery projects aren't separated from other renewable technologies by default — you have to filter
Technology Type == "Battery"yourself, covering both standalone BESS and storage co-located with, say, a solar farm. - A project resubmitted for planning can get a new REPD Ref ID, which — without extra logic — looks like a brand-new project rather than a continuation of an existing one.
For anyone tracking dealflow, planning risk or grid capacity, re-reading a full CSV every quarter and manually diffing it against your own spreadsheet doesn't scale.
The solution: UK BESS Pipeline Tracker
The UK BESS Pipeline Tracker on GeoFetch downloads the official REPD extract directly (no scraping), filters it to battery storage projects, and — using a snapshot persisted between runs — delivers only new and changed projects. You're never charged for re-delivering an unchanged project.
What you get per project
- Capacity (MW), development status, region, planning authority, and coordinates (native OSGB36 easting/northing)
- A full status history across runs (e.g. "Under Construction" → "Operational")
- The co-located generation project resolved to its name, technology and capacity, via REPD's own cross-reference — not a free-text label
- Explicit flags:
isNewSinceLastRun,isChangedSinceLastRun,operatorChanged— so a status change and an ownership change are never conflated - REPD Ref ID continuity: a resubmitted project is recognised as a continuation, not miscounted as new
Example output
{
"projectName": "AES Kilroot Station Battery Storage Array",
"capacityMW": 10,
"status": "Operational",
"previousStatus": "Under Construction",
"region": "Northern Ireland",
"planningAuthority": "Mid and East Antrim",
"isChangedSinceLastRun": true,
"operatorChanged": false
}
A free batch summary record (totals by status and region, total MW in the pipeline) is included with every run at no extra charge — useful for a quick market-density check before drilling into individual projects.
Getting started
- Go to the UK BESS Pipeline Tracker on Apify.
- Create a free Apify account.
- Optionally filter by region, capacity range, planning authority or status — or leave it unfiltered to track the entire pipeline.
- Run it again next quarter (or on a schedule): you'll only be charged for what actually changed.
