The NDA group announces CX Power as strategic developer for the Chapelcross green energy hub masterplan. It says the focus of the CX Power development is 135 acres of the available land within the unlicensed landholding of the NDA estate, adjacent to the former nuclear power site and wider nuclear licensed area, with plans including a potential 1 GW data-centre campus. evidence

- Precision scope
- Area centroid of the red-line boundary on page 7 ('Site Location Plan') of the developer's April 2026 consultation boards, registered to Esri World Imagery with a four-parameter similarity fit on nine road, track and building controls (RMS residual about 6 m, maximum 11 m; leave-one-out centroid shifts at most 2.3 m). The traced boundary encloses 56.1 ha and the point lies inside it, 79 m from its nearest edge. It marks the proposed campus land as a whole, not a building, the council's application red line or a surveyed position.
- Horizontal uncertainty
Not reported
The plan has no scale or coordinates; residuals measure only the fit of the consultation graphic to imagery of unknown date and accuracy, and hand tracing adds unquantified error. The 55 ha site extends about 1.3 km across, and building positions are not shown.

A locator places the site on the map. It is not a building footprint, a construction extent or a surveyed boundary unless the use scope is an official boundary, and even then it is a parcel or permit boundary.
