What is a smart energy system?

As part of an exciting energy revolution that's under way in Great Britain, a new smart energy system is being developed that will use digital technology to actively monitor what electricity the country needs, when it needs it - then suppliers can generate enough to meet demand. Smart meters are key to a modern smart energy system because they'll gather the information the energy networks require to react to the amount of energy needed. This means the system will be more flexible in actively managing supply and demand.

Why do we need one?

Our current energy system simply can’t map the demands from homes and businesses accurately, so a lot of energy goes to waste. A smart energy system, working with smart meters, will help reduce waste because it will know precisely where to direct our valuable resources. For example, if London's energy use peaks between 8pm and 10pm, and Newcastle's peaks between 7pm and 9pm, then resources can be redistributed to reflect this.

A smart solution

By upgrading to a smart meter you're helping to move Britain towards a cleaner, greener, lower-carbon economy. Good for the nation, good for the planet.

We all want to make big changes to help our planet, but sometimes to make big changes, we have to start small. Smart meters can't solve climate change on their own but with the smarter, more energy efficient system they help to create, they're a start.

Helping us be smarter with our energy

Smart meters are having a positive impact on how people use energy, with nearly three quarters saying they're doing more to save energy since getting one.1

Sarah, a mum of two from Chelmsford, says her boys no longer leave their gaming consoles on standby and she always makes sure they turn the lights off. By making a few changes around the house, she's seen significant savings on her gas and electricity bills.

Positive incentive to use energy outside peak times will help us as a nation balance supply with demand without having to build and generate more dirty and expensive energy. The National Infrastructure Commission say that a truly smart energy system could save the nation £8bn each year!
