‘Green Button’ gives Ontarians more control over electricity and natural gas bills

November 1, 2021  By Government of Ontario

London – More control is being given to Ontario’s families and businesses to deal with their natural gas and electricity bills with the province’s new Green Button standard.

It allows customers to track their energy use, reduce bills and save money. Green Button can help consumers make informed decisions and achieve energy savings of up to 18 per cent.

Ontario is the first province to mandate the standard.


“Families and businesses want to be in the driver’s seat when it comes to their energy bills,” Todd Smith, minister of energy, said. “Green Button is part of our commitment to give consumers more choice when it comes to their energy use and will enable easy and quick access to their consumption data through smartphone or computer apps so they can find customized tips to reduce energy use or switch electricity price plans to save money.”

Starting Nov. 1, the government is requiring nearly all regulated Ontario electricity and natural gas utilities to provide Green Button to their customers within 24 months. This builds on progress made by London Hydro and Festival Hydro, which voluntarily offer Green Button to their customers, which gave families and businesses in their regions the first opportunity in Ontario to find additional savings on their bills using this method.

Green Button lets customers download their natural gas and hourly electricity data in a standardized format from their utility and authorize the secure transfer of this data to applications of their choice. This real time data can then be accessed on their smartphone or computer. These apps can also analyze the energy data and provide customers with helpful energy-saving tips to reduce their energy bills and personalized retrofit options to achieve long-lasting savings.

“The Green Button standard ushers utilities into the modern technology era of open utilities, increased customer choice, and uniform energy management services for the benefit of customers,” Vinay Sharma, CEO of London Hydro, said. “Indeed, Green Button will manifest the true benefits of smart meter systems for customers.”

The implementation of the Green Button standard comes as the Ontario government celebrates one year of providing consumers with customer choice. For the first time, Ontarians can choose an electricity price plan that best suits their lifestyle and electricity usage. As of Nov. 1, 2020, most families, small businesses, and farms can select either a time-of-use (TOU) or tiered billing structure for their electricity usage. Over the past year, more than 280,000 Ontario electricity customers have used this choice to better manage their electricity bills by switching their pricing plan to one that is a better fit. Green Button provides families and businesses the information they need to better understand their energy use so they can make an informed decision on which price plan is right for them, helping them to lower their energy bills.

“Secure and automated access to energy data through Ontario’s Green Button program will empower consumers to make affordable, climate-friendly decisions for their homes and businesses,” Julia Langer, CEO of The Atmospheric Fund, said.

Festival Hydro has been collaborating with London Hydro to enhance their online customer engagement solutions since 2017, Jeff Graham, CEO of Festival Hydro, said. The collaboration included launching MyFestivalHydro powered by Green Button – a standard, easy-to-use platform for customers to access and take charge of their energy usage data.

“By working together, we have recognized cost efficiencies while providing our customers more online service options, with more to come in the future,” he said.
