ESB Upgrades Julianstown Substation with 10 MVA Capacity

ESB Networks has completed an upgrade at Julianstown 38 kV substation in County Meath, Ireland, doubling installed transformer capacity from 10 MVA to 20 MVA.

The project replaced two existing 5 MVA power transformers with two new 10 MVA units, adding 10 MVA of capacity. Transformer performance and operating limits are closely linked to cooling system design, particularly as electricity demand increases.

The additional capacity is equivalent to the electricity demand of approximately 2,500 homes and is intended to support population growth, new developments, and the electrification of heating and transport. As network assets operate under changing demands, thermal monitoring of transformer subsystems can also support equipment condition assessment.

Julianstown substation serves communities and businesses across County Meath.

“This upgrade at Julianstown 38 kV Station is an important investment in the electricity network across the northeast,” said James Finn, Network Capacity Deployment Manager at ESB Networks.
