Nalcor Energy’s chief executive Ed Martin is in Toronto this week for talks with the Ontario Power Authority and other Ontario energy officials about Newfoundland and Labrador’s latest megaproject: Nalcor’s development of the Lower Churchill hydro-electric project. Nalcor of course already has a $6.2 billion deal with Emera Inc. to develop the 824-megawatt Muskrat Falls project on the Lower Churchill. That power will move by undersea cable first to Newfoundland, then on to Nova Scotia. But Martin is also eyeing Ontario as a customer for the next step in the Lower Churchill: The 2,250-megawatt Gull Island project, upstream from Muskrat Falls. The Star takes a mainlander’s look at the two projects and their futures.
