Island power plan not most environmentally sound: critic

A plan put forward by an energy economist proposes reducing
pollution
emissions to almost one-tenth that proposed by B.C. Hydro.
Hydros plan calls for a natural gas power plant for Vancouver
Island
fed by a pipeline across Georgia Strait. The end result would be
1,850
tonnes of carbon dioxide pumped into the atmosphere a year by 2010,
Simon Fraser University professor Mark Jaccard predicts.
By contrast, a mixture of cogeneration, woodwaste and small hydro
power from around the province, fed to Vancouver Island via a new
power cable, would produce just 190 additional tonnes of carbon
dioxide.
Savings in harmful nitrous oxide emissions would be from 174 tonnes
under the B.C. Hydro plan to just nine tonnes under his plan.
The additional cost for these savings, Jaccard predicts, would be a
residential rate increase of 0.04 cents a kilowatt hour in B.C.
The report has had a lukewarm reception so far from both B.C. Hydro
and Nanaimo city council, but Jaccard, a former chairman of the
B.C.
Utilities Commission, isnt surprised the power company has yet to
do
an about-face.
Jaccard believes B.C. Hydro hopes to fix two problems with one
solution an aging power cable to Vancouver Island that needs
replacing
and an increased demand for electricity across the province.
Through B.C. Hydros solution, Vancouver Island will be paying the
price for all B.C.s increased energy needs, Jaccard says.
Youre going to get the emissions for the whole province, he says.
The economist believes three power plants will eventually be built
on
Vancouver Island simply because B.C. needs an additional 660
megawatts
of power, and the public utility will be under pressure to use the
gas
pipeline to make it pay for itself.
Meanwhile, Jaccard sees simpler solutions through many smaller
projects.
A model for the woodwaste solution is already taking place in
places
like Quesnel where energy-efficient wood-based burners are
replacing
old bee-hive burners that produced no energy.
The result is a dramatic reduction in particulate pollution.
The increase in NOx emissions in Quesnel have almost no
environmental
effect relative to the greater good from reducing particulates, he
says.
We have the double benefit of getting rid of NOx and particulates
in
Nanaimo while also reducing particulates in Interior communities.
Cogeneration is Jaccards second solution one already being explored
in
places like Europe. Jaccard sees more institutional cogeneration
instead of just industrial.
Its fairly easy to add aero-diffusion and reciprocating turbines,
he
says. Examples would be hospitals and colleges anywhere youve got a
fairly decent-sized boiler. It can even be apartment buildings or
office towers.
Jaccard believes the cost for this energy form will fall
dramatically
once experience and economies of scale reduce costs.
His third solution is small hydro projects either turbines in
rivers
or small retention dams.
Even considering sites too far from grids or limited by First
Nation
or environmental considerations, Jaccard believes B.C. Hydro could
easily realize between 300 and 1,000 megawatts from the remaining
sites.
An incredible response to B.C. Hydros own call for proposals is
proof
of the potential, Jaccard adds.
All these energy forms will entail private involvement.
Its hard to do the small stuff with the big elephant, Jaccard says.
These are more entrepreneurial projects.
Jaccard splits no hairs about his solution not being the
environmentally-friendly approach espoused by other B.C. Hydro
critics, who see reductions in use and a reliance of alternative
energy forms as the solution.
But if were burning waste anyway, why not get some electricity from
it? he says.
Environmentalists have embraced his report anyway, and at least
Jaccard says it buys time to see whether a gas pipeline to
Vancouver
Island is really needed.
Wind, tidal, solar and other energy forms are too distant to be
financially viable now, Jaccard says.
But building a super-sized gas plant will only put all B.C. Hydros
eggs in one basket, Jaccard says. Three to four years from now were
going to regret it once we see how cheap renewables are getting, he
says.
