In theory, P.E.I. has the potential to meet its own electricity needs. But half of its generating mix at present is from wind, which can't be relied on as a constant source of power, while the rest is expensive and comes from polluting oil and diesel plants. So the Island imports about 85 per cent of its electricity through New Brunswick, with about a third of that normally contracted from NB Power's Point Lepreau nuclear station and Dalhousie oil-fired plant. However, Point Lepreau has been offline for refurbishments since 2008, forcing Maritime Electric, the private provincial utility, to acquire most of its electrons on the expensive open market. The result has been steep price hikes for P.E.I. customers of about 25 per cent in the last three years. They pay the highest average energy rate, 16 cents per kilowatt-hour, of all the provinces — well above the national average of 10.1¢/kWh.

The provincial government waded in last fall with a new five-year pact with Maritime Electric that guarantees a 14 per cent rate cut starting March 1, followed by a two-year freeze. Premier Robert Ghiz's Liberal government is effectively subsidizing the deal by taking on some of Maritime Electric's debt. The province has also scaled back its ambitious plans for additional wind power from a 500-MW target unveiled three years ago, to 130 MW hoped for in spring 2010, to just 40 MW of utility-owned turbines under the P.E.I. Energy Accord.
