🇮🇪 Ireland — EirGrid / iSEM
EirGrid (ROI) + SONI (NI) operate the all-island Single Electricity Market (iSEM). Ireland tracks SNSP — System Non-Synchronous Penetration — the unique metric for real-time wind/solar share of grid inertia. Current limit: 75%, target 95%.

SNSP — System Non-Synchronous PenetrationEirGrid target: 95%
What is SNSP?
SNSP measures what percentage of electricity comes from non-synchronous sources (wind, solar, HVDC imports) vs synchronous generators (gas, hydro) that provide natural grid inertia.
Current limit: 75% — EirGrid is the only TSO in the world to have pushed this so high. Target is 95% SNSP via grid-forming inverters and synthetic inertia.
Ireland's wind resource and small grid size make it a global laboratory for high-penetration renewables operation.
