Keeping You & your neighbours connected.


ESB Networks is constantly striving to provide stakeholders and customers with better information, insight, and transparency.  As a result we have just refreshed the ESB Networks Availability Capacity Heatmap. 

The Heatmap provides a snapshot of available transformer capacity for new demand and generation customers. It is a user-friendly and interactive map that shows the available network transformer capacity, in terms of how much demand or generation could be added into a substation without reinforcement.

It is mainly for our large Industrial & Commercial customers, and other customer groups like small businesses, farming, and small community projects.

It helps potential customers have a better understanding as to where to connect, enabling the easy identification of potential capacity in the vicinity of customer sites.
