The WhenToPlugIn app shows you the live carbon intensity forecast and lets you know when the electricity in your home will be cleanest over the next 48 hours to help you plan your electricity usage.
What difference does it make?
Carbon intensity, the amount of CO2 emitted to produce 1kWh, varies by hour, day, and season due to, among other, weather conditions and changes in both electricity supply and demand. If one million Brits used the app and switched to using their washing machine when the electricity in their area was produced by cleaner energy sources, we could collectively help take a whopping 36,500 cars off the road!

What is WhenToPlugIn?
This is our new app! It tells you the best times of day to ‘plug in’, so you can make smarter energy choices at home; saving those energy intensive tasks for when they’ll have the least impact on the planet.
WhenToPlugIn is a handy tool for your mobile phone that helps you make smarter energy choices at home. It's powered by carbonintensity.org.uk, the same carbon intensity forecasting tool built by National Grid ESO, The Environmental Defense Fund Europe, The University of Oxford and WWF that powers the Green Light Signal.
