An energy storage facility with a synchronous compensator from Siemens will be built in Ireland

Siemens Energy has initiated an innovative energy storage project in Shannonbridge, Ireland, with a value exceeding EUR 85 million. In addition to its primary function of storing and supplying energy to the grid, the system will incorporate a synchronous capacitor to stabilize grid voltage.

Hybrid system as a network aid

Siemens Energy intends to deploy a hybrid energy storage facility in Shannonbridge, comprising a synchronous device, a 160 MWh battery, a power conversion system, energy management, and supplementary equipment to bolster the medium-voltage network.

With a project value surpassing EUR 85 million, construction has commenced. The synchronous capacitor will be pivotal in preserving grid stability, particularly given the increasing prominence of wind and solar farms in power systems.

Energy storage with synchronous compensator – functions

The synchronous capacitor within an energy storage system plays a critical role in maintaining grid voltage stability, serving two primary functions. Firstly, it ensures that short-circuit power and inertia remain at levels necessary for network stability.

Secondly, in case of short circuits, the synchronous capacitor restores voltage to the appropriate levels. Siemens Energy anticipates that such devices will see increasing adoption, particularly as wind and solar farms play a larger role in power systems.

Moreover, earlier this year, Ireland was identified by Aurora Energy Research as one of the top five most promising energy storage markets in Europe.
