    Hydro One Limited history, profile and corporate video

       Hydro One Limited is an electricity transmission and distribution service provider headquartered in Toronto, Ontario, Canada.

    HISTORY

       Hydro One history dates back to 1906 when the Ontario Legislature passed the Power Commission Act establishing the Hydro-Electric Power Commission of Ontario (HEPC).

       In 1974, the Hydro-Electric Power Commission of Ontario (HEPC) was renamed Ontario Hydro.

       In 1999, Ontario Hydro was restructured into five separate entities: Ontario Power Generation, Ontario Hydro Services Company, Independent Electricity System Operator, Electrical Safety Authority, and Ontario Electricity Financial Corporation.

       In 2000, the Ontario Hydro Services Company was renamed Hydro One Incorporated and reorganized as a holding company.

       In 2014, Hydro One acquired the assets and customers of Norfolk Power.

       In 2015, Hydro One became a publicly-traded company on the Toronto Stock Exchange.

       In 2017, Hydro One announced the purchase of the U.S. energy company Avista but the purchase was blocked in 2018 by the Washington Utilities and Transportation Commission.

       In February 2017, Hydro One Brampton was acquired by Alectra Utilities.

       In May 2017, the Ontario government completed the sale of 60% shares of Hydro One.

       In 2018, the Ontario government announced they had sold over 14 million shares of Hydro One to OFN Power Holdings.
