The Independent Electricity System Operator (IESO) is a Crown corporation responsible for operating the electricity market and directing the operation of the bulk electrical system in the province of Ontario, Canada. It is one of eight Independent System Operators in North America.
The IESO was established in April 1999 as the Independent Electricity Market Operator (IMO) under the provincial government of premier Mike Harris in preparation for deregulation of the province's electrical supply and transmission system. As part of government plans to privatize the assets of Ontario Hydro, the utility was split into 5 separate Crown corporations with the IMO responsible for directing the flow of electricity across the high-voltage, province-wide network owned by Hydro One and other transmission companies. It was also given the responsibility of managing and operating the competitive wholesale electricity market and working with neighbouring jurisdictions to manage an integrated North American electricity network.
The IMO was renamed to the IESO in January 2005 as a result of the passage of Bill 100, which redefined the direction of deregulation and also led to the creation of the Ontario Power Authority.
The IESO is an independent, not-for-profit entity. It is governed by a board whose directors are appointed by the government of Ontario, its fees and licences are set by the Ontario Energy Board and, most importantly, it operates independently of all participants in the electricity market.
In April 2012, the Energy Minister of Ontario Christopher Bentley introduced legislation in Parliament to merge both the Ontario Power Authority and the IESO . The merger is expected to take place in Fall 2012.

“Where beauty is worshipped for beauty’s sake as a goddess, independent of and superior to morality and philosophy, the most horrible putrefaction is apt to set in. The lives of the aesthetes are the far from edifying commentary on the religion of beauty.”
—Aldous Huxley (1894–1963)
“There are two great unknown forces to-day, electricity and woman, but men can reckon much better on electricity than they can on woman.”
—Josephine K. Henry, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 4, ch. 15, by Susan B. Anthony and Ida Husted Harper (1902)
“I candidly confess that I have ever looked on Cuba as the most interesting addition which could ever be made to our system of States. The control which, with Florida, this island would give us over the Gulf of Mexico, and the countries and isthmus bordering on it, as well as all those whose waters flow into it, would fill up the measure of our political well-being.”
—Thomas Jefferson (1743–1826)
