Fans in front of their TVs, gas-fired plants on standby. An English match and a heatwave triggered a price shock in the British power grid.

Millions of switched‑on fans, air conditioners, and mass tea‑making during the England–Ghana World Cup match pushed the British power grid to its limits. Under African‑style heat and windless conditions, the operator had to pay gas power plants nearly 4 million pounds for just a few hours of operation, driving electricity prices to astronomical levels.

The kettle effect and a heat‑driven blow to the system

Not long ago, we published an expert article titled “104 matches, millions of kettles and air‑conditioned stadiums. The energy rollercoaster of the 2026 World Cup.” It presented various perspectives on the relationship between the energy market and the football world championship. The theses and forecasts it contained quickly proved accurate. Exactly a week ago, the British system operator had to deal with the combination of two extreme phenomena — a record heatwave sweeping across Europe and the so‑called TV pickup, a sudden, mass surge in electricity demand during breaks in major events.

Experts from consultancy LCP Delta estimated that the goalless draw between England and Ghana, during which Harry Kane wasted the best chance, caused a sudden increase in power demand of 300 MW during halftime (when millions of fans went to their kitchens to switch on electric kettles and open refrigerators) and another 225 MW immediately after the final whistle. Interestingly, the water‑break pauses introduced for players on the pitch did not spread out this load or ease the grid — they were too short and irregular for viewers to change their habits.

4 million pounds in a few hours. Who profited from emergency supply?

To maintain grid stability at a moment when the evening sun stopped powering photovoltaics, NESO had to deploy all available reserves. In total, between 17:30 and 22:30, the operator paid gas power plants as much as 3.85 million pounds, with the lion’s share going to two facilities:

• 2.7 million pounds went to the Seabank gas power plant (owned by SSE) near Bristol for rapidly increasing energy production.
• 1.0 million pounds went to the Killingholme gas power plant (owned by Uniper) in North Lincolnshire.
• An additional 2.9 million pounds was spent by the British operator on emergency electricity imports from continental Europe during the match.

Rates for gas power plants, which had to start up their units at lightning speed, reached 1000 pounds per megawatt‑hour. This is nearly 14 times the average market price from June last year. Analysts emphasize, however, that this was not an attempt at market manipulation by the companies but a natural valuation of an extreme energy shortage. Batteries previously charged with solar energy were also used to manage short‑term fluctuations.

The heat dome paralyzes Europe’s energy system

The situation in the UK and on the continent was worsened by the fact that a powerful anticyclone (the so‑called heat dome) brought an almost complete lack of wind, drastically reducing output from wind farms. Additionally, high temperatures caused failures and generation limits at five British conventional power plants.

The crisis affected all of Europe, making easy rescue with cheap imported energy impossible:

• In France, where temperatures exceeded 40°C, four nuclear power plants had to reduce output because river water became too warm to cool reactors effectively and safely.
• In the UK, a rare summer electricity‑supply warning was issued on Wednesday. Although NESO ultimately withdrew it after securing 1.7 GW of imports from the continent, the price for this emergency energy rose to 1400 pounds/MWh — nearly 20 times above the June norm.
