Create an app to help Ontarians unlock the potential of Green Button electricity data.

The Energy Apps for Ontario Challenge is offering $50,000 in funding to software developers for the best new, proof-of-concept apps that help Ontarians unlock the potential of Green Button-enabled electricity data. Green Button is a standard which offers a secure way for consumers to share electricity data from smart meters. Apps can help Ontario households and businesses better understand and manage their electricity use, so they can make informed decisions and take action.

Find out more about how the Green Button Initiative is helping drive electricity conservation and economic growth on the Resources page.

Organized by MaRS Discovery District and funded by the Ontario Ministry of Energy, the Energy Apps for Ontario Challenge is open primarily to Ontario residents and businesses; however, residents of the United States and the rest of Canada (excluding Quebec) may compete in the Best App Created Outside of Ontario category.

To get access to the resources needed for the Energy Apps for Ontario Challenge please visit the Resources page.
