Outages and security of supply

Outages are the clearest signal of a grid under stress — and the strongest argument for battery storage. Here is the market reading, from a resilience angle, behind the Stromfee BESS optimizer.

Stress signals (real data)

What the Day-Ahead market reveals about grid stress · 2026-06-14

Without live outage feeds for Ireland, we read system stress where it is measurable and published: on the electricity market. A very high spot price indicates scarcity (demand approaching available supply); negative prices indicate a surplus (renewable generation above demand). The values below are the real ENTSO-E Day-Ahead prices for the day.

How the Irish grid is run

Who keeps Ireland in balance

EirGrid operates Ireland's high-voltage transmission grid and is the transmission system operator: it balances generation and demand at every instant, jointly with SONI in Northern Ireland across the all-island system. EirGrid publishes real-time system data (System Information, demand and wind dashboards) and flags system-stress situations. At the European level, ENTSO-E coordinates the transmission operators and publishes market and cross-border flow data. The detailed regulation — negative-price rules, market obligations — is set out, where documented, at /ie/rules/.

Illustrative — no real-time outage feed

Why do outages justify storage?

Most large supply incidents stem from extreme events — winter storms, heatwaves — that stress generation and transmission at the same time. A battery can pick up load instantly when the grid drops out, while emergency services are activated or the grid is restored.

Batteries respond in milliseconds to frequency deviations, injecting or absorbing power to hold the balance. The same battery that charges when prices are low (often negative) and discharges at peak hours is also available as backup supply.
