Manitoba Hydro is asking the provincial regulator, the Public Utilities Board, to approve electricity rate increases of 3.5 per cent in each of the next two years. It also warns that it will likely need rate hikes above the rate of inflation in the future if it is to meet government debt-reduction targets. "These proposed increases will help ensure Manitoba Hydro has the financial resources available to handle the risks created by our $24-billion debt load and factors that are out of our control like fluctuating interest rates, export market prices and water levels," Jay Grewal, president and CEO of the Crown-owned utility, said in a press release Wednesday.
