The '''Independent Electricity System Operator''' ('''IESO''') is the [[Crown corporations of Canada|Crown corporation]] responsible for operating the [[electricity market]] and directing the operation of the [[electrical system|bulk electrical system]] in the province of [[Ontario]], Canada. It is one of seven [[independent system operator]]s in [[North America]].

The IESO was established in April 1999 as the '''Independent Electricity Market Operator''' ('''IMO''') under the provincial [[government of premierOntario]] during the premiership of [[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 5five 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]].

TheAs a Crown corporation, IESO is anowned independent,by not-for-profitthe entity[[government of Ontario]] but operates at arms-length. It is governed by a board whose directors are appointed by the governmentprovincial of Ontariogovernment, 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 [[ChristopherChris Bentley (politician)|Chris Bentley]] introduced legislation in [[Legislative Assembly of Ontario|provincial Parliament]] to merge both the [[Ontario Power Authority ]] and theIESO.<ref>{{Cite web|url=https://www.thestar.com/news/queenspark/2013/05/24/possible_opa_merger_would_reduce_public_consultation_on_planning_oppositions_says.html|title=Possible ''IESOOPA ''merger would reduce public consultation on planning, oppositions says|date=May 24, 2013|website=thestar.com}}</ref> The merger iswas expected to take place in Falllate 2012.
