What does electricity cost?

Day-ahead price now

€/MWh

This is the wholesale exchange price — not the rate on a household electricity bill.

Cost of imports

per hour

Current imports multiplied by the exchange price: what a full hour would cost at this level.

Since midnight today

Electricity imported since midnight valued at exchange prices, less export revenue.

Today's day-ahead price

Electricity is sold a day ahead: the dashed section has not happened yet, but its exchange price was settled yesterday.

What does that actually mean? · of imports

this many times more than every household in Hungary combined, on average

this far in an electric car on one hour of imported electricity

this many electric kettles switched on at once (2 kW)

When should you use electricity?

below the daily middle — worth it around the daily middle above the daily middle — avoid tap or hover an hour

Is it raining in the Danube catchment? · 7 nap0mm in the basin today

The rainfall is a modelled forecast, not a measurement. The blue glow indicates timing only — when rain falling on the catchment could reach Paks — not volume: most of it evaporates or soaks in before ever reaching the Danube.

Paks · up close

The river did not run dry. The cooling-water intakes sit at a fixed height — once the Danube drops below them, the pumps cannot lift water. On top of that, the law caps the temperature of the water returned: 500 m downstream of the outflow channel the Danube may not exceed 30 °C. Together these two limits forced the plant back.

How much cooling water is needed?

Plant fully shut down

2.5m³/s

The plant's design basis assumed the 100-year minimum was more than 1 m higher than the 2018 record. The current level has gone past that assumption.

Scheduled vs. actual grid load · 24 hours0MW below plan

0MW below schedule · past hour

Below schedule 0 / 0 quarter-hours That’s 0 GWh less than the schedule since midnight

The “schedule” is MAVIR’s own forecast, so the gap includes forecast error — on its own it does not prove deliberate saving, but it shows the direction well.

What the electricity came from · 24 hours

The layers add up to consumption: whatever is not generated at home is covered by imports.
