Take part in a trial to help decide the future of energy! Greenwich Energy Hero is a service being piloted in Greenwich which helps you use electricity more effectively and earn rewards - all from the comfort of your home.Sign-up Find out more
Greenwich Energy Hero is a 12 month trial intended to help you and your neighbours use electricity more efficiently at home. By sending notifications via an app, the digital service will alert you when electricity supply is lower in your area. By using less electricity during this period, you’ll receive rewards. This is important as the supply of electricity is shifting towards solar and wind which produce electricity at variable rates, and the demand for electricity is changing too.
We’re looking for 100 homes across Greenwich to take part in this exciting 12 month trial which will launch in June 2019, and last for 1 year. By taking part you’ll help us to test out this new technology, and your feedback will inform how we can improve and perfect the service, which, in the future, has the potential to be rolled out to homes across the UK. You’ll also be compensated for taking part in the trial.
A Green Doctor will install a small device in your home to measure your electricity usage, and connect you to the Greenwich Energy Hero app
The Greenwich Energy Hero app lets you track the electricity use in your home in real time
You will receive an alert that there is a Peak Response Event via your app when electricity supply is lower- on average once or twice a month, with advance notice
If you accept the alert, you reduce your electricity usage for the suggested time- a few hours
You will be rewarded for your action with points which you can convert into vouchers for yourself or a donation to a local charity
Due to rising populations and a move over to renewable energy sources (which can produce variable amounts of electricity), there can be occasions when demand for electricity is higher than supply. Reducing the amount of electricity being used at certain peak times is the most efficient way of solving the problem, rather than building new power stations, or keeping old stations available for occasional use. Many large companies already take part in Peak Response Events, and we want to see if households can also take part in these actions too. If successful, it would ensure that we can continue our move over to renewable sources such as solar or wind, without the need to rely on back up fossil fuel power sources.
The National Grid is the network of cables that transfers electricity from where it is made (such as power stations, wind farms) to where it is used in homes and businesses.
The peaks of high demand of electricity happen when many households are using a lot of electricity at the same time- for example on a cold, dark winter's night when lots of lights, electric cookers and heaters and tumble driers are being used; or at the half-time in a big football match when everyone turns on the kettle.
Lower supply of electricity might occur on a cloudy and windless day when there is less solar and wind power being produced, or if a coal or nuclear power plant is turned off for maintenance.
A smart meter is supplied by your electricity supplier, and it measures how much electricity (or gas) your household is using (often every 30 minutes) and sends this information to your supplier where it is used to calculate your bill.
This project is using a similar meter, but it measures your electricity use more often (every 6 seconds or so) and cannot be used for billing. It is being used to calculate your reward for reducing your electricity usage after an alert.
In the future, if this trial and others like it are successful, these technologies are likely to be combined.
