Ontario Announces 25-Year Integrated Energy Plan for Electricity and Fuels

The Ontario government released its first integrated energy plan, called “Energy for Generations,” on June 12, 2025. According to the province, the plan sets out a 25-year strategy to meet Ontario’s future energy needs by coordinating electricity, natural gas, hydrogen, and other energy sources under a single approach.

The plan is intended to address an expected 75 percent increase in electricity demand over the period, as stated by the province. Ontario reports that it will invest in energy infrastructure and modernization of the electricity grid in response.

The province says the plan is organized around four principles: affordability, security, reliability, and clean energy. Measures described include investments in energy efficiency, new electricity generation, storage, and distribution. Ontario states that the plan will make use of competitive procurements and, according to the government, the largest nuclear buildout on the continent, aiming for over 99 percent zero-emission electricity by 2050.

The government says it plans to increase exports of electricity, nuclear technology, medical isotopes, and engineering expertise, and to support grid connections with other Canadian provinces. Ontario states it will make it easier for individuals and businesses to generate, store, and manage their own electricity with technologies such as rooftop solar and batteries.

The province intends to end siloed energy planning by integrating electricity, fuels, and new technologies, which it describes as a way to respond more quickly to changes in demand. The government also reports it will protect access to natural gas and other fuels and will release Ontario’s first Natural Gas Policy Statement.

Ontario says municipalities, businesses, industrial partners, and Indigenous communities will be part of implementing the plan. The announcement includes plans to increase funding for the Indigenous Energy Support Program to $25 million annually, as well as raising loan guarantees for the Indigenous Opportunities Financing Program to $3 billion. The province states it will expand funding to support First Nations energy capacity.

According to Ontario, public and stakeholder consultations drew 136 submissions. Legislative changes from the Affordable Energy Act, 2024, provided the legal framework for this plan. The full plan is published as “Energy for Generations” and is available on the province’s website.
