ESB Networks Availability Capacity Heat Map

At ESB Networks we are committed to improving the experience of our customers. As part of this commitment, we have developed our interactive Capacity Heatmap. It contains capacity information on all our 3-phase LV, MV and HV DSO substations. It provides an interface that enables the easy identification of potential transformer capacity in the vicinity of your site. An excel file is available to download from the download section on this page.
We envisage that the map will be used to inform initial discussion between ourselves and our customers. Although we have taken steps to ensure the accuracy of the map, it cannot replicate the level of accuracy provided by the detailed assessment carried out as part of the formal application process. Please read the accompanying notes and important details section to understand what the map does and does not provide.
If the Available Capacity Heatmap indicates that there is insufficient capacity to accommodate your development, please contact us to discuss the next steps. We will always work with customers to find solutions.
