Power stations
Checks on this page
Each feed is judged by the age of its newest data against its own timetable: “late” means the last check found nothing newer. Settlement period now: SP–.
Britain’s large power stations, unit by unit: what each is generating now, what’s holding output back, and the reasons operators have published — read at one shared moment across every fuel.

About these figures
Notified and delivered · registered capacity · not shown
How it works
These figures are expected output, not meter readings. Each reactor tells the system operator every half hour what it expects to generate (its physical notification) and the most it can export (its maximum export limit), and this page shows the lower of the two for the current half hour.
Notified and delivered can differ
A notification can run ahead of what a reactor delivers. On 16 September 2026 Heysham 2 Reactor 7 notified 640 MW with a 545 MW export limit, and EDF reported 554 MW: taking the lower figure gets much closer. Metered output for each unit arrives days later.
Registered capacity isn’t how much a reactor can make today
Bars measure against each unit’s registered generation capacity, which is fixed in the registration data. Ageing AGRs routinely run below it, so a reactor at 85% of registered capacity can still be at its normal full load.
Not shown on this page
It doesn’t show metered output, fuel, or why an operator chose a level beyond what its outage messages say. Stations outside the balancing mechanism don’t appear. The illustrations are stylised, not survey-accurate.

About these figures
Starting up · available, not running · mixed signals · not shown
How it works
These figures are expected output, not meter readings. Each unit tells the system operator every half hour what it expects to generate (its physical notification) and the most it can export (its maximum export limit), and this page shows the lower of the two at the time shown, never less than zero.
Starting up and shutting down
Notifications can ramp within the half hour, so a unit starting up or shutting down may show part of its output.
“Available · not running”
The unit has an export limit above zero but notified no output: it could run if called on, but isn’t generating this half hour.
Mixed signals and missing data
A unit that notifies output but has an export limit of 0 MW shows as not generating.
Not shown on this page
It doesn’t show metered output, heat supplied by the CHP plants, or the gas burned. The illustrations are stylised, not survey-accurate.

About these figures
Held at the limit · Wilton · small units · not shown
How it works
These figures are expected output, not meter readings. Each unit tells the system operator every half hour what it expects to generate (its physical notification) and the most it can export (its maximum export limit), and this page shows the lower of the two, never less than zero.
Held at the export limit
When a unit notifies more than its export limit, it counts at its limit.
Wilton’s figure covers the whole site
Sembcorp’s unit is registered as the Wilton site, not the biomass plant alone, so its 182 MW registered capacity is larger than Wilton 10 itself. When the site is taking power from the grid its notification goes negative; the page shows that as not exporting.
Small units can send mixed signals
A small unit can notify a few megawatts with an export limit of 0 MW, as JG Pears did on 16 September 2026 (5 MW notified, 0 MW limit). Taking the lower figure shows it as not generating, and a gap that small isn’t flagged as export-limited.
Not shown on this page
It doesn’t show metered output, heat supplied by the CHP plants, or the fuel burned. Biomass plants outside the balancing mechanism don’t appear. The illustrations are stylised, not survey-accurate.

Wind farms right now

Output by farm and unit, against registered capacity. Rotors turn faster the more of its capacity a farm is using, and stop when it isn’t generating.The four largest onshore wind farms

Lead party is the company registered for the units, often a trader rather than the owner. Names marked † aren’t in the register; they are inferred from the unit code: Beinn Tharsuinn, Blary Hill, Clashindarroch and Douglas West; T_TRLGW has no name in the register.

About these figures
Curtailment · big farms at zero · register oddities · not shown
How it works
These figures are expected output, not meter readings. Each wind unit tells the system operator every half hour what it expects to generate (its physical notification, based on its own wind forecast) and the most it can export (its maximum export limit), and this page shows the lower of the two at the time shown, never less than zero.
Curtailment isn’t taken off
⚠ When the system operator pays a farm to turn down (curtailment), that appears as a separate balancing instruction and isn’t taken off these figures.
Big farms showing zero
Sofia is still being commissioned, so some of its units can show 0 MW.
Register oddities
Galloper’s unit 22 is registered at 386 MW but its export limit never goes above about 81 MW, so its “in use” figure looks low. Thanet’s two units each report a 150 MW limit, so the farm’s total looks doubled. Walney unit 4 appears twice in the register and is counted once here.
Not shown on this page
Many smaller onshore farms, especially in England and Wales, don’t register units in the balancing mechanism, so they aren’t listed and the onshore total is an undercount. The page doesn’t show wind speed or metered output. The illustrations are stylised, not survey-accurate.

About these figures
The sun · batteries · two farms, one square · register oddities · not shown
How it works
These figures are expected output, not meter readings. Each solar unit tells the system operator every half hour what it expects to generate (its physical notification, based on its own sunshine forecast) and the most it can export (its maximum export limit), and this page shows the lower of the two at the time shown, never less than zero.
Output follows the sun
Solar output peaks around midday, falls through the afternoon, and every unit here reads zero at night.
Co-located batteries
Batteries can import as well as export, so their figure is kept between the import and export limits and can be negative.
Two farms, one square
EDF’s Burwell solar farm is registered as Beechgreen Energy Farm (T_BURWS-1). Its neighbour, Octopus’s Breach Solar Farm (T_BRCHS-1), connects to the same Burwell 400 kV substation. They keep separate rows in the tables and share one illustration.
Register oddities
Breach is registered at 50 MW but has reported a 67 MW export limit, above its registered size (its panels total about 68–70 MWp). Sutton Bridge’s export limit has been below its 49 MW registered capacity.
Not shown on this page
Britain has far more solar than the units listed: most of it is embedded in local distribution networks and shows up to the system operator as lower demand, not as generation. The page doesn’t show irradiance or metered output. Batteries that are approved or bought at Cleve Hill, Breach and Sutton Bridge aren’t listed because they have no BM unit or aren’t confirmed as built. The illustrations are stylised, not survey-accurate.
