About Us

The Association of Power Producers of Ontario (APPrO) represents electricity generators and other stakeholders in the generation community, and serves as a leading advocate on policy and regulatory issues. Ontario is undertaking generational electricity investments, moving an already robust electricity system towards becoming an energy superpower.

As Ontario's voice for power producers, we advocate for policies and regulations that ensure a reliable, affordable, and secure power system, and enable timely investment in generation and infrastructure. We support effective market and procurement design, frameworks that promote efficiency, transparency and fair competition, integrated system planning, and a strong domestic electricity value chain that sustains well-paid local jobs, and long-term value for Ontario ratepayers and the economy.

Our Impact

APPrO is Ontario's leading advocate for power producers, representing member companies responsible for generating most of the province's electricity. For 40 years, APPrO has shaped energy policy, and given the generation sector a unified voice in government and regulatory proceedings.

History of APPrO

For the first 17 years of its operation, the organization was known as IPPSO, the Independent Power Producers' Society of Ontario.

In 2002, when Ontario's electricity market was officially opened to competition, the organization began a process in which it broadened its scope to include more generators, and changed its name to APPrO, the Association of Power Producers of Ontario.

Since then, APPrO has been the key voice of the province’s generation community. APPrO is Ontario's leading association for power producers, advocating to protect and promote Member interests on policy and regulatory issues that are critical to the success of the sector, and the economy.
