Almost 50% of Electricity Came From Renewable Sources in February as New Peak for Wind Energy Is Recorded

Why It Matters

The surge in renewable generation demonstrates Ireland’s accelerating decarbonisation trajectory and reduces reliance on fossil fuels, while record demand peaks test grid flexibility.

Key Takeaways

• Renewable share hit 48% in February, up from 39% January.
• Wind contributed 41% of total generation, 1245 GWh produced.
• Record wind output 3,898 MW on 14 Feb, surpassing 2025 peak.
• System demand fell to 3,027 GWh, lower than January.
• Saturday demand peaked at 5,408 MW, new Saturday record.

Pulse Analysis

Ireland’s renewable penetration approaching the half‑mark marks a pivotal step toward the EU’s 2030 climate objectives. By delivering 48% of electricity from clean sources, the island nation not only narrows its carbon footprint but also strengthens energy security amid volatile fossil‑fuel markets. The upward trend from 39% in January reflects both seasonal wind advantages and the cumulative impact of recent policy incentives that have accelerated solar and on‑shore wind deployments across the grid.

The wind sector’s performance in February set a new benchmark, with a 3,898 MW instantaneous output that eclipsed the previous record. Such high‑capacity generation tests the grid’s balancing mechanisms, prompting greater reliance on advanced forecasting, demand‑response schemes, and short‑term storage solutions. Grid operators like EirGrid are investing in digital control platforms and flexible interconnectors to accommodate these peaks without compromising reliability, illustrating how Ireland is modernising its infrastructure to handle a renewable‑heavy mix.

Looking ahead, the combination of a modest drop in total demand and a record Saturday peak underscores the evolving consumption pattern as winter heating loads rise. Continued investment in offshore wind, battery storage, and cross‑border capacity will be essential to meet higher peaks while keeping import dependence low. Policymakers are likely to tighten renewable procurement targets, leveraging the February data as evidence that ambitious goals are achievable and that the Irish power system can sustain higher renewable shares without sacrificing stability.
