Screening a site of your own?
Swindon approves 100% of battery storage schemes. Redline puts that number, and everything else the record holds, against your own boundary: the authority’s actual approval rate and decision times, every designation inside the red line, agricultural grade, 1 m LIDAR earthworks, how contested the grid is, and yield with a P90 — before you spend on a consultant.

What this site sits on
The recorded coordinate falls on land surveyed as Grade 4 agricultural land.
REPD gives one representative coordinate per scheme, not the site boundary, so this describes the point on record rather than the whole site — a large site can straddle a designation edge. Boundaries come from planning.data.gov.uk, which publishes for England only.

How big is Mannington Battery Storage Plant?
Mannington Battery Storage Plant has a recorded installed capacity of 49.9 MW. That figure is the capacity registered in REPD, which is the scheme as consented — the metered output of a site can differ.
Who operates Mannington Battery Storage Plant?
REPD records the operator as Still Waters Green Technology. Ownership of built renewable assets changes hands regularly and REPD is published quarterly, so treat this as the operator of record rather than confirmation of who owns it today.
When was Mannington Battery Storage Plant approved and built?
The application was submitted on 21 November 2017. Permission was granted on 7 December 2018, 13 months later. The site became operational on 1 October 2021, 34 months after consent.
Source: Renewable Energy Planning Database (REPD), Department for Energy Security and Net Zero, Open Government Licence v3.0, plus planning designation boundaries from planning.data.gov.uk (England only). REPD is published quarterly and covers schemes of roughly 150 kW and above. Capacity is the installed capacity on record, not metered generation. Operator is the operator of record at the last extract, not confirmation of present ownership. Reference 7024.
