This is the fifth, and final, post in a series inspired by a UKStudy that concluded a “truism” for natural gas in the coming
decades is ‘want wind, need gas.’”
My previous post noted that the
need for variable generation capacity, presumably primarily natural gas-fired,
does not decrease as wind capacity increases over the next decade, although the annual generation
from ‘peaking’ type sources may drop from about 20TWh annually, to 17TWh
annually.[i] The decline for gas producers may be more
than offset by the removal of coal-fired generation. In Ontario, it is frequently noted the costs
of the feed-in tariff programs for renewable (FIT and microFIT) have not yet
impacted bills. I’ll demonstrate that
isn’t entirely true. I’ll explore market
mechanisms required in a system that includes intermittent generation that is provided
with priority purchase status; and the alternate, non-competitive, mechanisms
Ontario has substituted for market mechanisms.
That will provide the basis to calculate a figure to add to the
accounting for the cost of Ontario’s wind strategy.
