Association of Power Producers of Ontario (APPrO)
APPrO is a non-profit organization representing more than 100 companies involved in the generation of electricity in Ontario, including generators and suppliers of services, equipment and consulting services. APPrO members produce power from co-generation, hydro-electric, gas, coal, nuclear, wind energy, waste wood and other sources. APPrO's members currently produce over 98% of the electricity made in Ontario. 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.
