Screening a site of your own?
Redline runs the record on your own boundary in South Oxfordshire: 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 Urban 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.

When was EFDA JJET Fusion Flywheel approved and built?
REPD does not record a submission date. REPD does not record a grant date. The site became operational on 1 January 2006.
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 6865.
