About London Hydro

London Hydro's Building

London Hydro is a Local Distribution Company that services the City of London, Ontario, Canada. With a peak load of 694 megawatts, we deliver a safe and reliable supply of electricity to over 168,000 customers from the residential, institutional, commercial and industrial sectors, through over 3,100 kilometres of overhead and underground cables, spanning 420 square kilometres of service territory. As a wholly-owned subsidiary company, we operate much like a private entity under the Ontario Business Corporations Act, paying an annual dividend to our sole shareholder, the City of London. In essence, all Londoners own London Hydro.
