Energy Storage Ireland is pressing EirGrid to raise its ambition as the national LDES procurement framework advances, warning that the proposed minimum capacity of 201MW still falls far short of the Government’s 500MW target for 2030. In its response to the ongoing consultation, the organisation welcomed progress but stated that the mechanism requires greater clarity and a more competitive design if Ireland is to meet its renewable integration and security of supply goals at pace.

ESI argued that long duration storage is central to stabilising the grid as renewable penetration increases, reducing curtailment and cutting dependence on imported fossil fuels. The organisation highlighted that more storage capacity would support lower wholesale electricity costs by enabling a more flexible, efficient system that can absorb excess renewable generation and dispatch it when demand rises.

Pat Lambert, policy analyst at ESI, said that effective long duration storage will be crucial for system stability, energy independence and the delivery of Ireland’s climate commitments. He emphasised the consumer benefits of a more balanced grid that relies less on volatile fossil fuel markets.

Chief executive Bobby Smith added that while the consultation is a milestone, it is only a starting point. He noted that the Government’s stated ambition for significantly expanded storage capacity is not reflected in the current minimum procurement figure, calling for a clearer pathway to the full 500MW by 2030. Smith also raised concerns that the proposed 10 year contract duration will limit investor confidence, recommending a minimum of 15 years to align with international norms and drive better value.
