In 1975, concerns about rapidly changing financial and energy markets as well as environmental and safety concerns led to the
Darlington project becoming part of the 5-year long Ontario Royal Commission on Electric Power Planning (RCEEP) study that assessed Ontario's future energy needs for the years

Following the completion of Unit 2 at the
