What is LDES?

What is Long Duration Energy Storage and why do we need it?

Long Duration Energy Storage (LDES) refers to technologies that can store energy for 8 - 12 hours, making them essential for balancing supply and demand in a renewable-powered grid. By storing excess renewable energy and releasing it during peak demand, LDES also cuts emissions, lowers system costs, and prevents renewable curtailment - making our energy system cleaner, cheaper, and more secure.

8% of wind power generated in ROI in 2024 was lost due to grid constraints and curtailments

LDES is a vital element in the upgrading of Ireland's grid infrastructure and therefore vital for Ireland’s transition to a cleaner, more reliable energy system and cheaper electricity for consumers. In fact, studies show that sourcing all system services from zero-carbon options like batteries could save Ireland €117 million a year by 2030 and avoid nearly 2 million tonnes of emissions.
