Screening a site of your own?
Braintree 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 2 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.
Braintree’s record on battery storage

How big is Slamseys Energy Storage?
Slamseys Energy Storage has a recorded installed capacity of 10 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 Slamseys Energy Storage?
REPD records the operator as Gridserve Energy Storage. 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 Slamseys Energy Storage approved and built?
The application was submitted on 6 July 2017. Permission was granted on 15 September 2017, 2 months later. The site is recorded as under construction and has no operational date yet.
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 7000.
