TORONTO, ONTARIO--(Marketwire - Dec. 21, 2011) - An Ontario Energy Board (OEB) decision expected to be handed down this week could plant a ticking timebomb in the City of Toronto's electrical grid, says Rod Sheppard, President of the Society of Energy Professionals. Toronto Hydro has applied to the OEB to have its' rates set through a Cost of Service (COS) rate application heard by the OEB, rather than through a hearing under the Incentive Regulation Mechanism framework.
