How to Interpret the Map — Layer Key
Northern Powergrid primary / BSP / GSP
Major primary and grid-level substations; visible from map zoom 8.
Point markerNorthern Powergrid distribution substation
Local distribution-level assets; visible from map zoom 13. Neither marker implies spare connection capacity.
Point markerWhat This Layer Shows
Two separate layers use Northern Powergrid’s Substation Sites List: major sites (Grid Supply Points, Bulk Supply Points and Primary substations) and distribution substations. Selecting a marker exposes the available site attributes.
Information may include the station name, primary voltage, station type, transformer rating, reported firm capacity, supplying upstream substation and geographical reference. Provider redactions for very small customer groups are preserved.
The detailed distribution layer requires map zoom 13 or higher; the major-sites layer starts at zoom 8. Very dense viewports have a 1,000-record display cap, with a warning to zoom closer.
Why It Matters for Your Site or Property
Public substation and capacity information helps early stage project screening, network planning and comparisons between candidate locations.
The network operator’s data cannot guarantee the available connection headroom, reserved capacity, point of connection or construction feasibility.
Planning and Property Impact
Use the data for preliminary network context and request a current connection assessment from Northern Powergrid before committing to site designs or commercial assumptions.

Important Limitations
- This dataset covers Northern Powergrid networks only, not every GB electricity distribution network.
- Distribution sites serving small customer numbers have redacted fields for privacy.
- Maplify caps dense views at 1,000 points, so users should zoom in before treating an area as comprehensively mapped.
- Published firm capacity is not the same as new-connection capacity and does not indicate safe positions for excavation.
Common Use Cases
Land and energy developers
Identify nearby published primary and grid assets and available attribute data.
Grid and EV consultants
Explore publicly mapped assets before obtaining formal operator capacity information.

Frequently Asked Questions
Do I need a paid API key?
No. Maplify uses the provider’s open Substation Sites List records API directly without a subscription.
Why do no distribution markers appear at low zoom?
Detailed distribution assets only load at zoom 13 or higher to avoid an incomplete overview of tens of thousands of records.
