What are you planning?

The same prices answer three quite different questions. Pick yours and we will open the right one.

Charging an EV
Say how much you need and how fast your charger is, and get the cheapest unbroken stretch tonight with what it will actually cost — not a list of scattered cheap hours a car cannot use.Show me →
Heating with electricity
Heating is a multi-day decision, so it needs the outlook rather than tonight's prices — and the honest reach of that outlook, which we publish per zone and never round up.Show me →
Solar or a home battery
The one question this page normally answers backwards: not when power is cheapest to use, but the stretch when it is worth the most to send back or discharge into.Show me →

Every day gets one of four labels

Compared with the same zone's last sixty days, never against a fixed price — so “expensive” means expensive for here, at this time of year, which is the part you cannot work out for yourself. Cool is cheap, warm is dear.

  • CheapWell below this zone's recent normal — the day to move usage into.
  • NormalOrdinary for this zone, this time of year.
  • ExpensiveAbove normal. Worth shifting what you can.
  • ExtremeThe top few percent of recent days. Avoid the peak hours.

What you get

Prices, hour by hour
The day-ahead market result for today and tomorrow, updated hourly. Kept at the market's native 15-minute resolution and shown by the hour.
Find a cheap stretch
Pick how long you need the power on — one hour, two, three, five — and get the cheapest unbroken window. A dishwasher cannot use three cheap hours scattered across a day.
The days ahead, with their accuracy
Each day labelled against this zone's own recent normal, and each carrying the accuracy measured at that range — a five-day label is a weaker claim than tomorrow's, and it says so.
A note before your week
One email, on the day you choose, with the days worth planning around. Only ever the days we can stand behind.

An outlook that admits what it does not know

Most price forecasts show you a number everywhere. Ours is measured per zone against prices that actually happened, and shown only where it cleared both bars we set in advance — separating cheap days from expensive ones (AUC ≥ 0.75) and ranking the ordinary days in between (ρ ≥ 0.65). Today that is 14 of 24 zones.

Outlook published
Separation and day-ranking, as measured for the predictor that serves each zone.
Prices only
These show prices and no outlook. A confident label that is barely better than a coin flip is worse than none.
