Westinghouse with the AP1000 and Candu Energy Inc. with the EC6 were asked by OPG to prepare detailed construction plans, schedules and cost estimates for two reactors. The reports must be ready by June of this year and will be submitted to the Ontario government for selection and go-ahead, or not. With Ontario’s unique generation mix of baseload/intermediate/peak hydro (8,000 MW), nuclear (13,000 MW), frackgas/oil (10,000 MW), coal (3,300 MW until shutdown in 2014), and intermittent wind (2,000 MW) and solar generators (482 MW), the operating characteristics of the new nuclear units will need to be carefully considered.
