Canadian Provincial Electric Grid Operators to Spend $1 billion to Accommodate Wind Power.

This is an opinion piece. The author apparently needs a long lecture about Denmark and the ten homes powered by wind hydrogen on the island of Utsira in Norway.

EDMONTON - It's official: The glorious future of abundant free energy has been put on hold. In May, the Alberta Electric System Operator (AESO) announced that the province's grid could not safely accommodate more than 900 megawatts of wind-power generation, a target that will be met late next year. Proposals for 3,000 more MW of production have been thrown into indefinite limbo at an estimated cost to producers of $6-billion; meanwhile, the province is already spending $1-billion to strengthen the transmission system so that even the 900-MW cap can be reached. In Ontario, meanwhile, the grid operator warned late last month that 5,000 MW -- about one-fifth of the province's current peak consumption -- is probably the absolute technological limit. (A total of 1,280 MW of wind capacity is already in operation or being built.)...

...The depressing corollary is that even in reaching the modest limits now being laid down by the grid police, Alberta and Ontario are relying implicitly on the relative sluggishness of their neighbours in adopting wind technology, using interconnections with other provinces and states to off-load excess power and cover shortfalls. So the system operators' warnings aren't just a sign that wind has reached a dead end in their home provinces. They also mean that B.C., Saskatchewan and parts of the U.S. Northeast will never be able to get major wind projects off the ground if they are to continue to serve as an energy release-valve for their wind-harnessing neighbours...

Energy Probe's analysis of hour-to-hour capacity factors at Ontario wind farms shows output declining disconcertingly in the morning, just when we greedy energy hogs are getting out of bed, turning on appliances and lights, and going to work. On a month-to-month basis, data from this summer show wind output remaining flattest during the hottest periods. And the AESO has found that in Alberta's southern wind corridor, the turbines spin like crazy when the chinook is blowing and little electricity is needed; in the still air of serious cold snaps, when loads are high, the turbines grind stubbornly to a stop...

...As an internationally observed rule of thumb, wind farms are expected to deliver, on average, 30% of their theoretical maximum power output. On the basis of partial data, Energy Probe expects the three major farms in its study to come in at 24%-27% over a full 12 months. And that's not even including the showpiece Windshare turbine at Toronto's CNE, which delivered a mean capacity factor of just 14.7% in its first 42 months of operation.
