New Brunswick has a modest amount of excess generating capacity and exports surplus power  to P.E.I. and the northeast United States. But its mix of power plants — with lots of oil, diesel and coal — is dirty, generating nearly twice as many greenhouse gases per megawatt of capacity as Ontario, and more than 10 times as much as Quebec.

Things will get substantially cleaner as the 40-year-old Dalhousie oil-fired plant shuts down this year and 320 MW in wind generation starts up by 2014. But the biggest question mark in the province's electricity future is the 635-MW Point Lepreau nuclear station. It was taken offline in 2008 for a planned 18-month, $1.4-billion refurbishment that would extend its life by 25 years. Major problems have set the completion date back to 2012, and the work is at least $1 billion over budget.

New Brunswick's transmission links to the U.S. will skyrocket in strategic importance starting in 2017, when the announced $6.2-billion Lower Churchill hydro development  comes online and Newfoundland and Labrador seeks to export that electricity to New England via underwater cable to the Maritimes.
