It’s 1990 and Chris Waddle, England midfielder, steps up to the penalty spot. The 60,000 people in Turin’s Stadio delle Alpi watching him and the fate of England football go silent.
He takes a breath and fires a shot at Bodo Illgner, the German goalkeeper. It careers over the crossbar and misses – England are out of the World Cup. The now famous image of Paul Gascoigne crying into his shirt is beamed across millions of UK television screens.
There’s a shuffling on the sofas in front of those TVs as the population gets up to make a cup of tea, get a drink or turn on the oven. Millions of kettles, lights and fridges are powered up as the country collectively despairs. The demand for electricity across the country soars.
This is what’s called a ‘TV pickup’ – the moment during a popular television event when there’s a break and viewers unwittingly cause a huge surge of demand from the National Grid.
It’s these moments that have caused some of the biggest spikes in UK electricity demand. Here we look at what’s caused them:
What? Football World Cup Semi Final: England v West Germany
When? Wednesday, 4 July 1990
Electricity demand: 2,800MW – equivalent to 1,120,000 kettles (based on 1MW = 400 kettles), or 4.3 Drax-sized generation units (there are six 645MW units at Drax)
After that fateful penalty miss the population made for the kitchen. The match was watched by an estimated 26 million people in the UK, and when full time was called they caused a 2,800MW surge in electricity demand.
What? The Thorn Birds
When? 22 January 1984
Electricity demand: 2,600MW – 1,040,000 kettles – 4 Drax units
A sleeper hit, The Thorn Birds was a one-off American mini-series about a fictional sheep station in the Australian outback. Based on the novel of the same name, it was broadcast in the UK following building up a huge following in the US when it was aired in 1983. By the time it arrived on UK shores there was clearly enough of that excitement to create a surge of electricity demand – one of the largest in UK TV history.
What? Football World Cup Quarter Final: England v Brazil
When? Friday, 21 June 2002
Electricity demand: 2,570MW – 1,028,000 kettles – 4 Drax units
Broadcast early on a Wednesday morning in the UK due to time differences with South Korea, where the game was played, the match saw England put up a solid fight against overall tournament winners Brazil. A goal from Michael Owen provided early hope and at half time TV viewers left their screens to cause a huge 2,570MW spike in demand. By the time the game had reached its conclusion, Brazil had won thanks to a chipped Ronaldinho free kick that fooled England keeper David Seaman and those viewers who had lasted the duration caused a slightly smaller 2,300MW surge.
What? Eastenders: Lisa admits shooting Phil
When? Thursday, 5 April 2001
Electricity demand: 2,290MW – 916,000 kettles – 3.5 Drax units
In one of the most dramatic plot developments in UK TV history, Lisa Shaw, played by actress Lucy Benjamin, admitted to shooting her former boyfriend, Phil Mitchell. An estimated 22 million viewers turned on to see the dramatic reveal. When it was all over they caused a surge of 2,290MW, more than five times the normal pickup of 400MW seen at the end of an average Eastenders episode.
What? The Darling Buds of May
When? Sunday, 12 May 1991
Electricity demand: 2,200MW – 880,000 kettles – 3.4 Drax units
One of the more wholesome entries to the list, this British comedy drama racked up a huge following during its 20-episode run from 1991 to 1993. The peak was early in the first season, when the third ever episode saw the Larkin family take an unhappy holiday to Brittany. The family’s escapades drew a large audience and prompted a surge equivalent to 880,000 kettles being switched on at the same time.
What? Rugby World Cup Final: England v Australia
When? Saturday, 22 November 2003
Electricity demand: 2,110MW – 844,000 kettles – 3.3 Drax units
A unique sporting entry to the list as England ended as winners. More than 12 million people watched England beat Australia, with the largest electricity demand coming at half time and not at full time, when audiences were presumably still celebrating Jonny Wilkinson’s last minute drop goal.
What? The Royal Wedding – Prince William and Kate
When? Friday, 29 April 2011
Electricity demand: 1,600MW – 640,000 kettles – 2.5 Drax units
The biggest and most celebrated Royal Wedding in a generation, the marriage of Prince William and Kate Middleton attracted an audience of 24 million in the UK alone. Energy demand peaked at 1,600MW when the bride’s carriage procession returned to Buckingham Palace. This is the largest TV pickup in recent years, which hints at how changing viewer habits, on demand watching and smart TVs are changing the need for power and making TV pickups a rarer occurrence.
How do we deal with TV pickups?
Because the level of electricity needed to power the country can’t be stored, when there is a spike in demand it needs to be met quickly by a similar increase in real time generation.
To manage the supply and demand for events likely to cause electricity surges, the National Grid forecasts electricity need for large events like World Cups and major TV events.
The Grid can then put contingency measures in place to manage the huge changes in demand in real time. It does this through a suite of tools called the Balancing Mechanism, which allows it to access sources of extra power in real-time.
If it forecasts a period of high demand, the Grid will keep a number of power stations on reserve, ready to deliver additional electricity if needed.
If it wasn’t for this careful management of electricity by the Grid and the power stations like Drax supplying it, that cup of tea next time England crash out of a major sporting event would not only be tainted with disappointment but cold, too.
