The project was commissioned by Ireland’s state-owned xf(ESB) to meet Dublin’s recent, unprecedented upsurge in demand for electricity, due to the proliferation of new data centers.

Hitachi delivered a 220 kilovolt (kV)/110 kV substation with gas-insulated switchgear, including the protection and control SCADA system enabling an advanced power system management and monitoring of equipment status while in service.

Overview

– Delivered a fully integrated, high-voltage substation close to Dublin’s digital business hub at Castlebagot, fast-tracking the standard two-and-a-half-year execution time to just 18 months, to keep the city’s growing number of large, increasingly important data centers running smoothly 24/7.

Outcomes

– Early collaboration with ESB ensured a design that fulfilled the utility’s availability and reliability requirements.

– Leveraging Hitachi Energy’s vast knowledge of utility grid codes and connection practices in different countries enabled fast project execution.

– 70% saving with gas-insulated switchgear, compared to the air equivalent.
