Right now
Grid under pressureThe grid is under more pressure than usual. Demand is high relative to available clean generation.
Current grid conditions
How the all-island electricity system is doing right now.
The grid is under more pressure than usual
Grid under pressureDemand is high relative to available clean generation. Easing heavy electricity use for a while helps the grid.
Official data: Supported by EirGrid Group Data
System demand today
All-island electricity demand from EirGrid’s public dashboard — production required to meet national consumption.
Solar generation today
All-island solar from EirGrid’s public dashboard, plus Surpl-connected exports where available.
Weather outlook
How temperature, wind and cloud may affect demand and generation over the next day or two.
Temperatures around 11–20°C, mostly light winds, often cloudy, mostly dry
Surpl estimateNear Ireland (all-island)
Over the next 24–48 hours: Temperatures around 11–20°C, mostly light winds, often cloudy, mostly dry. Cloud cover and sunshine affect solar output; wind and temperature shape grid demand.

Recent warnings
Earlier system notices for context. Official EirGrid and Surpl analysis are always labelled separately.
- Official EirGridnotice3 May 2026
Planned transmission maintenance (May 2026)
EirGrid published notice of planned maintenance affecting parts of the transmission system. The notice was forward-looking and aimed at market participants and the public for awareness. Surpl includes it here as historical context on the energy-signals page.

Morning tight-margin signal (Surpl analysis)
Public dashboard data suggested demand was rising faster than wind and conventional plant could comfortably cover for a morning period. Surpl labelled this as analysis to distinguish it from any official EirGrid notice. No amber or red alert was recorded for this entry in the public log.

Amber Alert — evening generation shortfall
EirGrid issued an Amber Alert because available generation was expected to be tight during the evening peak. Consumers were asked to be mindful of electricity use where practical. Surpl’s public log preserves the headline and timing for context. Follow EirGrid and your supplier for official instructions.

Strong renewables window (Surpl analysis)
Based on public Smart Grid Dashboard readings, Surpl flagged an afternoon window with a high share of wind on the system and relatively lower demand. This is Surpl’s plain-English summary — not an official EirGrid alert. Members might use it as context for timing flexible loads when that feature is enabled.

Wind variability notice (January 2026)
EirGrid noted increased variability in wind output across the all-island system. The notice was informational — there was no consumer amber or red alert at the time. Surpl republished this as context only. For official wording and any active alerts, always check EirGrid directly.

What the signals mean
Short explanations — open any item for detail.
Lots of clean energy
What it means
A large share of electricity is coming from renewables such as wind.
Why it matters
Often a good time to run charging or heating when generation is cleaner.
Stable conditions
What it means
The grid is within normal ranges with no active notices.
Why it matters
No action needed — use electricity as usual.
Grid under pressure
What it means
Demand is high relative to clean generation, or an alert is active.
Why it matters
Easing heavy use for a while helps the grid and can lower fossil-heavy generation.
Weather outlook
What it means
Temperature, wind, cloud and sunshine over the next day or two.
Why it matters
Weather shapes both demand and how much solar and wind can contribute.
Warning history
What it means
Earlier notices kept for context — official EirGrid and Surpl analysis are labelled separately.
Why it matters
Past events help you judge whether today looks typical or unusual.
