Total power being consumed across the island of Ireland right now — homes, factories, offices, everything.
Demand rises on cold mornings and winter evenings and falls overnight.
Learn more →How much electricity wind turbines are producing right now.
When wind is strong, gas-fired power stations run less, cutting carbon emissions.
The forecast shows expected output in the coming hours.
Learn more →How much electricity solar panels are producing right now across Ireland.
Solar is a growing but still small contributor — output peaks at midday and is zero at night.
The forecast shows expected output in the coming hours.
Learn more →How much of Ireland's electricity demand is currently being met by imports through the undersea interconnectors to Great Britain.
When Ireland is a net exporter, this shows zero — the grid is self-sufficient and selling surplus abroad.
For a breakdown by individual cable (EWIC, Greenlink, Moyle), see the Interconnector Flows section below.
Learn more →Everything that isn't wind, solar, or net imports — primarily gas-fired power stations, but also batteries and hydro.
Calculated as Demand minus Wind minus Solar minus Net Interconnector flow.
This is the dispatchable backbone that balances the grid when renewables fall short.
Learn more →The heartbeat of the electricity network — must stay at exactly 50 Hz.
If more power is being used than generated, the frequency dips; if there's too much supply, it rises.
Large deviations trigger automatic safety responses to protect equipment.
Learn more →SNSP measures what share of electricity is being supplied by sources that are not physically spinning in sync with the grid — wind turbines, solar panels, batteries, and imports.
Traditional generators like gas or coal turbines spin in lockstep with the grid's 50 Hz frequency, and their spinning mass acts as a natural shock absorber against sudden changes. Non-synchronous sources lack this inertia.
Above about 75% SNSP, the grid becomes harder to keep stable, so EirGrid may curtail wind or run extra conventional plant to maintain a safety buffer.

The lower the better. Ireland's 2030 climate target is 105 g/kWh.
When wind and other renewables are generating strongly, intensity falls because gas-burning plants run less.
Learn more →Breakdown of electricity being generated in the Republic of Ireland right now, by fuel type.
Renewables (wind + hydro) are shown as a single bucket — the centre shows what percentage of ROI generation is currently renewable.
Gas is the dominant dispatchable fuel. Data updates with each pipeline run.
Learn more →All three cables linking Ireland to Great Britain — EWIC, Greenlink, and Moyle — are High-Voltage Direct Current (HVDC) submarine links.
They carry power as direct current rather than the alternating current used on the grid, so they are not synchronised with either grid at the ends.
That lets them join separate AC systems without matching frequencies, makes the power flow fully controllable in either direction, and cuts losses over long undersea distances.
Learn more →Total electricity being consumed across the grid, in megawatts. The all-island figure combines the Republic of Ireland and Northern Ireland.
Demand peaks on winter weekday mornings and evenings, and drops overnight and at weekends.
Learn more →Electricity being produced by wind turbines, in megawatts.
Actual output is shown alongside the short-term forecast.
When wind is strong it displaces fossil-fuel generation, cutting carbon emissions and lowering electricity costs.
Learn more →Electricity being produced by solar panels, in megawatts.
Output follows daylight hours and peaks in summer afternoons.
Solar is still a small but growing part of Ireland's generation mix.
Learn more →Electricity flowing between Ireland and Great Britain through undersea cables.
Positive values mean Ireland is importing; negative means exporting.
EWIC and Greenlink connect to Wales, Moyle connects Northern Ireland to Scotland.
Learn more →Grams of carbon dioxide emitted per kilowatt-hour of electricity generated in the Republic of Ireland. EirGrid does not publish CO₂ data for Northern Ireland.
Lower is cleaner. Ireland's 2030 climate target is 105 g/kWh — the dashed yellow line.
Intensity falls when wind and solar output is high and gas plants run less.
Learn more →The electrical frequency of the grid, measured in hertz and shown as an hourly average. The target is exactly 50.000 Hz.
Frequency drops when demand exceeds generation and rises when generation exceeds demand.
Large deviations can damage equipment.
Learn more →The share of electricity coming from non-synchronous sources (wind, solar, batteries, imports) at any moment, expressed as a percentage.
EirGrid currently limits SNSP to 75% to maintain grid stability.
Pushing this instantaneous limit up to 95% or higher is key to reaching 80% renewables on average by 2030.
Learn more →The percentage share of each fuel type in the daily electricity supply.
Gas is the main dispatchable backup when renewables are low.
The mix shifts day by day as wind output and demand change — a greener mix means less carbon emitted per unit of electricity.
