What Happens When Millions of People Switch the Kettle On at Once
Picture the scene: England are playing a crucial football match. Half-time arrives, millions of people head to the kitchen, kettles start boiling, ovens are switched on and fridges are opened.
For a few minutes, electricity demand across England suddenly jumps.
This is known as the TV pickup effect – a well-established phenomenon where large numbers of people respond to the same televised event at roughly the same time, creating a sudden increase in electricity demand.
Although streaming and on-demand television have made these events less predictable than they once were, major sporting fixtures can still create significant changes in electricity use.
At SolarTherm UK, we’re interested in what this means for the future of the electricity grid – and how technologies such as solar panels, battery storage and smart energy management can help households take greater control of their electricity use.
What Is the TV Pickup Effect?
The TV pickup effect occurs when a large number of people change their electricity consumption at the same time.
It traditionally happens during:
- Half-time during major football matches
- The end of popular television programmes
- Advertising breaks
- Major royal events
- National broadcasts
- Other events attracting exceptionally large audiences
The effect is particularly noticeable when people switch on high-power appliances such as kettles, ovens and microwaves.
NESO, the organisation responsible for balancing Great Britain’s electricity system, has recoded some enormous historical examples. The largest recorded TV pickup occured after the penalty shoot-out during the 1990 World Cup semi-final between England and Germany, when electricity demand increased by around 2,800 MW. That is an extraordinary amount of additional electricity demand arriving in a very short period.
Why Does TV Pickup Matter to the Electricity Grid?
The electricity system has to maintain a constant balance between supply and demand. When demand suddenly increases, additional electricity generation or other forms of flexibility are needed to keep the system balanced.
NESO forecasts electricity demand using factors including weather, consumer behaviour and major events. Its control room can then respond to sudden changes using tools such as the Balancing Mechanism, additional generation and flexible technologies.
The important point is that a TV pickup does not mean the National Grid is suddenly unable to cope. These events are anticipated and planned for. Instead, the demonstrate one of the fundamental challenges of running a modern electricity system: millions of individual decisions can collectively have a significant impact on national electricity demand.
The TV Pickup Effect in 2026
The phenomenon hasn’t disappeared. NESO specifically prepared for the 2026 FIFA World Cup, forecasting that England and Scotland group matches could each produce an electricity demand pickup of around 600 MW.
However, the way we consume television has changed considerably. Streaming services, catch-up television and on-demand viewing mean fewer people necessarily watch programmes at exactly the same time. This has made traditional TV pickups less dramatic and less predicatable than they were several decades ago.
At the same time, households are using electricity for more purposes than ever before. Electric vehicles, heat pumps, home batteries, smart appliances and other electrical technologies are increasing the importance of managing when electricity is consumed, rather than simply how much is consumed.
It’s Not Just Television That Can Cause Energy Spikes
Large changes in electricity demand can happen for many different reasons. One example was the UK’s Clap for Carers events during the COVID-19 pandemic. NESO recorded an electricity pickup of around 800 MW as people returned indoors and switched appliances back on.
Weather can also have a major impact. Extremely hot or cold conditions can increase electricity consumption through heating, cooling and refrigeration. The electricity system therefore has to respond to a constantly changing combination of consumer behaviour, weather conditions, generation availability and renewable energy output.
Where Do Solar Panels Fit Into This?
Solar panels don’t directly stop a TV pickup from happening. If millions of households switch on their kettles at the same time, national electricity demand will still increase. However, solar PV allows individual households to generate some of their own electricity rather than purchasing all of it from the grid.
During daylight hours, your solar panels can generate electricity for your home while any surplus can be stored in a battery or exported to the grid. This gives homeowners greater control over where their electricity comes from and when they use it.
For example, instead of relying entirely on the grid to supply electricity later in the day, a household with solar and battery storage may be able to use energy that was generated and stored earlier.
How Battery Storage Can Help
A solar battery stores surplus electricity so it can be used when your solar panels aren’t generating enough. This can be particularly useful during the evening, when solar generation has fallen but household electricity consumption often increases.
Battery storage can help you:
- Use more of the electricity your solar panels generate
- Reduce your reliance on grid electricity
- Avoid purchasing as much electricity during expensive periods
- Take advantage of suitable time of use tariffs
- Increase your energy independence
- Potentially export surplus electricity when it makes financial sense
Modern batteries can also form part of a wider smart energy system, working alongside solar panels, EV chargers and smart tariffs. This is increasingly important as the UK electricity system becomes more flexible.
Can Solar Panels Protect Your Home During a Power Cut?
This is an important distinction. A standard grid-connected solar PV system will normally shut down during a power cut. This is a safety requirement designed to prevent electricity being fed back into the network while engineers may be working on the electricity supply.
However, some solar and battery systems can be installed with an Emergency Power Supply (EPS) or backup functionality. When correctly designed and installed, this can disconnect the property from the grid and allow the battery to supply selected circuits – or, depending on the system, a larger proportion of the home – during an outage.
So while solar panels don’t provide general protection against national electricity demand spikes, solar and battery storage with appropriate backup equipment can provide genuine additional energy resilience for your home.
Solar, Batteries and the Future of the UK Energy System
The TV pickup effect highlights something important about the UK’s changing energy system. Electricity demand isn’t static. As more households adopt electric vehicles, heat pumps, batteries and other electrical technologies, managing when electricity is generated and consumed will become increasingly important.
This is where technologies such as battery storage can play a much bigger role.
NESO is already using and planning for flexible technologies such as batteries and pumped storage to help manage changes in electricity supply and demand. During the 2026 World Cup, for example, NESO highlighted batteries as one of the technologies helping the system respond to expected demand increases.
For homeowners, this means a solar PV system can be about much more than simply generating electricity from your roof. A well designed system can combine:
- Solar generation
- Battery storage
- Smart energy management
- Flexible electricity tariffs
- EV charging
- Export payments
- Backup power where required
Together, these technologies can give homeowners greater control over their energy consumption and reduce their dependence on electricity purchased from the grid.
Why Solar and Battery Storage Could Make Sense for Your Home
The TV pickup effect is a fun example of how individual household decisions can collectively influence the electricity system. But for homeowners, the bigger opportunity is having greater control over their own energy. Solar panels allow you to generate electricity on your property, while battery storage lets you decide when that electricity is used.
The right system can therefore help you:
- Reduce your electricity bills
- Increase solar self-consumption
- Store surplus daytime generation
- Reduce grid imports
- Make better use of smart energy tariffs
- Prepare for future technologies such as EV charging
- Add backup capability where required
Every home is different, which is why system design matters. Roof orientation, available space, shading, electricity consumption, battery capacity, tariff choice and future energy requirements should all be considered before deciding what system is right for you.

Frequently Asked Questions
The TV pickup effect is a sudden increase in electricity demand that occurs when large numbers of people change their electricity usage at the same time, often during half-time or at the end of major televised events.
Yes. Streaming and on-demand television have reduced the frequency and size of some traditional TV pickups, but major sporting events can still create significant increases in electricity demand. NESO expected around 600 MW of additional demand during each England and Scotland group match at the 2026 FIFA World Cup.
Solar panels do not automatically protect a property against voltage surges caused by changes in grid demand. Appropriate electrical protection, such as surge protection devices, is a separate consideration. Solar and battery systems can, however, reduce reliance on grid electricity and may provide backup power when installed with suitable EPS equipment.
A standard grid-connected solar PV system will normally switch off during a power cut. A compatible solar battery system with EPS or backup functionality can continue supplying electricity to selected circuits, provided the system has been designed and installed for this purpose.
No. Solar panels can work without a battery. However, battery storage can allow you to store surplus solar electricity generated during the day and use it later, increasing your self-consumption and potentially reducing grid imports.
Yes. A battery can supply stored electricity to your home rather than requiring all of your electricity to come from the grid. Depending on the system and tariff, batteries can also be charged or discharged strategically to make better use of electricity prices.
It can be. A battery can store surplus daytime solar generation for use later in the day, while suitable export tariffs can provide payment for electricity sent back to the grid. The best system depends on your individual electricity usage and property.
