An overview map of WPD's West Midlands EHV networks (33kV and above), highlighting those circuits which are operating at or near their limits for the connection of any further Distributed Generation (DG). The reason for the constraint is shown as either a ‘thermal’ or ‘voltage’ limitation. The map provided here is in pdf format. We hope to update this with GIS data in the near future. https://www.westernpower.co.uk/our-network/distributed-generation-ehv-constraint-maps
