Wholesale prices for the interval covering this moment, bidding zone by bidding zone — countries with several zones appear once per zone, with its code in brackets. The average is arithmetic across zones, not weighted by demand: a small zone counts as much as a large one. The figures exclude network tariffs, excise duty and VAT.
What balancing cost, in the last 24 hours
Generation and consumption never match perfectly. The operator covers the difference through the balancing market, and that energy has a price of its own. The bars show the cost of balancing in each 5-minute interval.
data for the last 24 h · up to 12/09/2026, 22:15:00
539,012 EUR was paid for 6,234.6 MWh of balancing energy, that is 86 EUR/MWh on average. The most expensive interval: 21:10, 15,216 EUR.
288 of 288 intervals have a published price. Prices are those published by SEMO every five minutes (Imbalance Price Report, BM-025); the thirty-minute settlement price may differ.
Positive imbalance = the system had energy to spare (surplus); negative = it was short (deficit). The cost is the imbalance price times the volume; in surplus the money flows the other way, so the bar is negative. A negative price is real: then whoever had spare energy paid to get rid of it.
Source: SEMO, Imbalance Price Report (Imbalance Pricing Period) — the imbalance price and the net imbalance volume for each five-minute interval.
Who consumes: the base, the work rhythm, the day
An estimate from the shape of the consumption curve, not a measurement by customer category — that is not published in real time. Three parts: what never stops, what runs in shifts on working days, what switches on during the day.
archive up to 12/09/2026, 20:00:00
Over the last seven days consumption averaged 3,944 MW and ranged between 3,233 and 4,627 MW.
How it was measured: the median of the 02–05 hours over 8 Sunday mornings (3,241 MW) and over 28 working mornings, Tuesday to Friday (3,372 MW), across the last 8 weeks; the average over the last seven days. The parts are cut from one another in order and add up exactly to the average.
The parts are shapes of the curve, not customer categories: the base holds every household's fridge as well as a plant that never stops; the day holds single-shift factories too. “Industrial” and “household” would be words these data cannot defend.
The operator's consumption forecast
How much the country is expected to consume, hour by hour, according to the forecast the transmission operator publishes for today and tomorrow. The line is the forecast; the bars, consumption measured so far.
forecast issued 12/09/2026, 22:00:00 · EirGrid
The forecast is the transmission operator's, published on its own platform — not a model of ours. It is revised during the day; for each hour the latest issue is shown. The running hour, in the bars, only shows what has accumulated so far.
Ireland, in detail
What EirGrid and SEMO publish and no other country shows: grid frequency minute by minute, the operator's own carbon figures, the share of non-synchronous generation, and the wind and solar forecast next to what was actually produced.
Grid frequency, last hour
The frequency of the island's synchronous system (Ireland and Northern Ireland), minute by minute: the minute's average and the band between its minimum and maximum. The target is 50 Hz.
last published hour · up to 12/09/2026, 22:46:00 · EirGrid
EirGrid publishes samples every five seconds; we reduce them to minutes, with their average, minimum and maximum. The deviation is written in millihertz from 50 Hz.
System margin, today
How much is available in the plants against how much is being consumed, every five minutes, from SEMO's balancing market report. The margin is the difference; the reserves and the backup price come from the same report.
day of the last publication · 12/09/2026, 22:10:00 · SEMO
Source: SEMO, Imbalance Price Report (BM-025), every five minutes — “TotalUnitAvailability”, “ShortTermReserveQuantity”, “OperatingReserveRequirement”, “MarketBackupPrice”. Availability is the capacity units declare available, not generation; demand is EirGrid's quarter-hourly figure, taken at the nearest moment before the latest availability.
CO₂ intensity today, as published by the operator
How many grams of CO₂ per kilowatt-hour generated in Ireland, quarter-hour by quarter-hour, as EirGrid publishes them — not our estimate from the mix.
day of the last publication · 12/09/2026, 22:30:00 · EirGrid
EirGrid computes the intensity from generation by fuel and each plant's emissions. Our mix-based estimate elsewhere on the site uses average factors; here the figure is the operator's.
SNSP today — non-synchronous generation, All-Island
The share of non-synchronous generation (wind, solar, imports over DC cables) in what the whole island consumes, every half hour. EirGrid publishes it only All-Island.
day of the last publication · 12/09/2026, 22:30:00 · EirGrid
Non-synchronous generation gives the system no inertia; the operator caps it in real time, and the percentage says how much of the island was running, at that moment, on wind, sun and cables.
Wind: forecast and actual
The solid line is what was produced; the dashed one, what EirGrid forecast for today, latest issue.
forecast issued 12/09/2026, 22:00:00 · EirGrid
The forecast is the operator's, revised during the day; the latest issue is shown for each quarter-hour. The difference is not a grade for the forecast: the wind changes, and that is exactly why the operator revises it.
Solar: forecast and actual
The solid line is what was produced; the dashed one, what EirGrid forecast for today, latest issue.
forecast issued 12/09/2026, 22:00:00 · EirGrid
The forecast is the operator's, revised during the day; the latest issue is shown for each quarter-hour. The difference is not a grade for the forecast: the wind changes, and that is exactly why the operator revises it.
The intraday auctions, against the day-ahead price
The SEM market holds three intraday auctions after the day-ahead one: IDA1 the evening before, IDA2 in the morning, IDA3 at midday. Each re-corrects the price for the hours that remain.
delivery day September 11, 2026 · SEMOpx
Each auction's most expensive interval: IDA1: 409.76 EUR/MWh at 09:00 · IDA2: 294.31 EUR/MWh at 18:00 · IDA3: 299.02 EUR/MWh at 18:30
The difference against day-ahead is computed over the SHARED hours, not over whole averages: IDA3 covers only the evening, and its average next to the day's average would only have said that evenings are expensive. Intraday results are published late — verified: the auctions of 8 and 9 September 2026 appeared only in the night of the 10th — so the day shown is a finished one. The prices are the Republic's market (ROI); Northern Ireland has its own prices in the same document.
Northern Ireland, today
The island's other half: its own demand and generation, hour by hour, plus the Moyle cable to Scotland. The operator is SONI; the dashboard is shared with EirGrid.
day of the last publication · 12/09/2026, 22:45:00 · EirGrid
Northern Ireland has no country code of its own (it is GB-NIR) and shares the SEM bidding zone with Ireland, so the price is common and is not counted twice. The gap between demand and own generation is covered from the Republic and through Moyle; it is not a country's “import” but the balance of half an island. SNSP and frequency are not published separately for it: the system is synchronous across the whole island.
What the data centres consume
In Ireland, other people's computers are a quarter of the country's electricity. The official statistics count them separately, quarter by quarter: the coloured part is the data centres, the rest is everyone else.
published 2026-07-07 · Central Statistics Office, Ireland
“Metered consumption” means what passes through meters, not the system's generation: energy consumed on site, behind the meter, is not included. The figure is quarterly and appears about six months late, so it does not compare with the live consumption elsewhere on this page.
Live flows on interconnector lines
The flow measured right now on each physical border line, from the operational feed.

How the renewable share is computed
Σ(renewable sources, positive values only) / Σ(all sources, positive only).
Numerator: Onshore wind, Solar.
Denominator: 2,555 MW.
Pumped-storage hydro and waste are not counted as renewable — the first would double-count energy, the second is partly fossil and its biogenic fraction cannot honestly be separated.
Consumption — 24 hours
