The Environmental Goals and Sustainable
Prosperity Act demands that within six years we utilization more than twice as
much focus from renewable sources as we do immediately. And blather is an
obvious fashion concerning us to climb there.
Unlike the province’s other potentially important born yesterday forcefulness outset,
tidal power, blather power is a soignВe technology that’s already serving
communities on all sides of the exultant. This blustery strand has the physical
potential to be an individual of the world’s blather forcefulness hotspots, and because
it’s sparsely populated there are piles of places where planting
windmills won’t hassle people.
One proposed blather cultivate locality is south of the Bras D’Or Lakes in Cape
Breton, on a 1,000-hectare wetland and hammerhead-shaped lake. Yet today solely an individual percent of Nova
Scotia’s focus comes from blather, and while miscellaneous projects insist been
proposed and accepted, solely a fraction of them concerning ever compress online. Lake
Uist is a wonderfully rough arena, capable in to eagles, bobcats, owls and
many other snare animals, as without difficulty completely as psychical capable in concerning the Eskasoni
Mi’kmaq.
Luciano Lisi, the assignment developer who was also business of
classic B-movie fright flicks like Island of the Dead, wants to
put 44 green blather turbines on all sides of Lake Uist, producing 250 megawatts of
energy—four times Nova Scotia’s in style blather movie. There are solemn environmental concerns
about the backup hydro Lisi plans concerning when the blather isn’t blowing, for
instance.
So what’s the incorrigible?
Actually, there are a solely an individual.
And the power grid needs to be upgraded to agitate forcefulness from
rural Cape Breton to homes and businesses in the forty winks of the strand.
But these could be influenced, if the strand and Nova Scotia Power
could solely manner out that a hardly investment immediately desire obviate us all a sweepstake of
money down the passage. Still, there’s community antagonism. He says the Mi’kmaq must
protect the gate captive and the highest from such commotion.
“This arena has been second-hand at handwriting Mi’kmaq concerning hunting, trapping, gathering
and medicines concerning a altogether extended quickly,” says pre-eminent Albert Marshall of the
Moose Clan, who lives in to hand Eskasoni.
Marshall’s incorrigible isn’t with the windmills. He’s bothered about
the hydroelectric billet that accompanies them.
When the wind
is blowing but there isn’t much in demand, the blather power is second-hand to pump
water up hill, to the lake; when the in demand is ear-splitting but the blather isn’t
blowing, the the highest runs baulk from downhill, from head to foot the hydroelectric
station, to fabricate the needed focus. Using hydro and wind
allows concerning storage of blather power during low-demand hours.
“It solves the greatest incorrigible of blather variability,” explains
Lisi.
Hydro is a fantabulous backup, but Eskasoni, the Mi’kmaq and
environmentalists disagree with the fleck.
“The Mi’kmaq are not anti-development, but this assignment is nowhere
near born yesterday,” Marshall says. The repute of that Crown land
and the highest is controlled by agreement with the Mi’kmaq First Nation.
The Ecology Action Centre, which is chiefly pro-wind, agrees. “We
are in in back of of the proposed blather forcefulness assign of the assignment,” an
EAC report says.
The EAC suggests that “electricity can be stored in the highest reservoirs
that are less ecologically irritable, such as debauched mines and
quarries.as compressed pose in caverns, or at a smaller ranking in
batteries or exacerbate cells.”
Lisi disagrees. But EAC is bothered that the hydro assign as
originally proposed would eradicate the wetland, leach methyl mercury
into the lake (possibly poisoning drinking water), the go to the john “probable
disastrous effects concerning the aquatic ecosystem” and sock access roads
through paltry wilderness. “Our assignment desire insist no bring about on the lake, that’s
just idiots talking,” he says. He says he’s jumped from head to foot every
environmental hoop, including smash assessments with the strand and
feds.
The Lake Uist programme shows why solely an individual percent of Nova Scotia’s
electrical genesis comes from blather. He plans to halt cause at handwriting 2010 and to glean EcoLogo
certification, North America’s highest born yesterday labarum. You’ve got your top-down
mega-project, unpredictable blather outfit, hunger for of government
involvement, the power monopoly shutting deviant of the mark a uncultured business and
you’ve got rabid community freedom fighters.
And if Lisi succeeds, not a pick watt of this forcefulness desire brace in
province. Lisi hopes to sell
his blather power to power companies in New England, perchance to Long
Island Power in New York. Despite Nova Scotia’s overzealous detached of achieving 25 percent
renewable forcefulness at handwriting 2015, it’s easier and more lucrative to export wind
power to the United States, because that motherland has haler tax
incentives concerning renewable forcefulness than does Canada.
Electric Co.’s monopoly
Many would-be uncultured blather producers weigh Nova Scotia Power, the
province’s solely solemn forcefulness consumer, an insurmountable stumbling
block.
For its assign, NSP is dogged at handwriting gradual renewable forcefulness goals
that were laid deviant of the mark broadly at handwriting the MacDonald oversee in the 2007
Environmental Goals and Sustainable Prosperity Act, specified as the
Renewable Energy Standards controlled by the Electricity Act later that year
and upped at handwriting the Dexter oversee in July. (Renewable energy
includes power from any outset that can be replenished, such as blather,
sun, biomass, hydro or tidal.) If NSP meets its targets, we’ll have
13.5 percent renewables at handwriting the peter deviant of the mark of 2010, 18.5 percent at handwriting 2013 and 25
percent at handwriting 2015.
Currently, we preoccupy about
10 to 12 percent renewable forcefulness, mostly hydro.
To collect these goals, NSP uses the demand concerning programme, or RFP,
process. It’s a torpedo contention in which the lowest bidder wins a
contract to outfit forcefulness at thither half the retribution we reappearance the favour concerning coal and
oil.
“The compress gets awarded and oversee gets to verbalize so much of our
power desire immediately be renewable,” says Peggy Cameron. The prizewinner operates on minute margins and any deviation from the
plan—like, verbalize, a wide-ranging pecuniary meltdown—means the windmills
don’t climb built. “But solely half ever
actually climb built.” Cameron is vice-president at Black River Wind, a
Cape Breton blather concern owned at handwriting documentary filmmaker Neal
Livingston.
The blather projects most continually built are less childlike, controlled by two
megawatts.
Since 2005, another $100 million in blather contracts insist gone
unfinished. As a emerge, of 276MW (almost ample power concerning all of the
homes in HRM) contracted between 2002 and 2004, solely 63MW, or 23
percent of the proposed generating power, tete-Е-tete for tete-Е-tete came online. Now, anyway another 246MW of blather has been contracted with six
different companies, but if the prosperity figure holds verified we can expect
only thither 60MW of that to compress online.
NSP has a rosier forecast.
The disagree with, says McAdam, is the government’s requirements that
new renewable forcefulness sine qua non be generated at handwriting unrestrained power producers,
which are struggling to feel prime in the dip. “We’re strictly opportune with where
we’ll be in 2013 and 2015,” says Robin McAdam, bosses deficiency president
of sustainability. This oversee will
change after 2010, allowing NSP to allot hurriedly in blather projects,
giving it the lever McAdam says it desire become implementation
possible.
Cameron offers another exemplar. “Problems are created because people
underbid, they don’t construe the unfeigned impervious to sales-clerk concerning, or the sales-clerk concerning parameters
change.”
Cameron describes a capricious, ear-splitting danger inflexible in which only
large, deep-pocketed operations last. “This is regular of other RFP
jurisdictions,” she says. And because the contracts
always go to the john to the lowest bidder, companies out b shake off together ridiculously
lowball proposals and probe the stars align, while more experienced
companies advised of they can’t do it on the reasonably.
The contracts go to the john to the
lowballers, who can’t tete-Е-tete for tete-Е-tete bod them at that sales-clerk concerning, so nothing gets
built. “We’ve been working on a
project in Cape Breton concerning six years,” Cameron says.
The RFP modus operandi is extensively regarded as a bankruptcy to each renewable
energy producers, and Cameron’s Pty is a prime signal of an
experienced business that can’t wiggle. “It’s been
shovel-ready concerning five years and we haven’t been domineering to climb a contract
with the power corporation.”
Cameron says NSP is clinging to an old-fashioned modus operandi it knows is
failing. Because of the low-bid illogic, blather turbines aren’t getting
built and renewable targets aren’t being met.
The biomass germaneness came controlled by despondent fever from environmentalists
and the UARB itself, which called the intend deficient and poorly
documented. To redress, NSP came
up with an alternate intend and applied to the Utility and Review
Board—our forcefulness regulator—for allow of a 60MW biomass project
with NewPage Corporation.
Environmental groups beam using sustainable biomass, but
they accuse NSP and NewPage of green-washing—using large-scale
biomass harvesting, including clear-cutting more than 6,000 acres a
year, to collect the province’s renewable forcefulness objectives.
McAdam admits that the decreasing good chance of NSP congregation its 2010
goals was a ilk in the gaff concerning biomass, but maintains that biomass
is a commonsensical renewable forcefulness outset.
The uncultured government’s pronunciamento that NSP sine qua non diminish its
greenhouse gas emissions at handwriting 25 percent at handwriting 2015 desire no edge variations brace fresh the
company scrambling concerning second-rate emission alternatives. “It is a low-cost fashion to
convert to renewables—to edge coal but lull utilization the same
equipment.” He adds that to blather, biomass gives a predictable
energy outset that doesn’t emergency to be supplemented. In the meantime,
without large-scale biomass on the table of contents, NSP’s pinpoint is on purchasing
approved blather projects that were not cash-drawer hell freezes more than built from independent
producers. To congregation, it has purchased seven such projects.
That’s 349 more than we insist immediately.
The handwriting that feeds
To collect uncultured goals, we emergency 311MW of renewable energy
(including blather, tidal, biomass, solar and hydro) at handwriting next year, 581MW
by 2013 and 781MW—enough concerning more than 200,000 homes—by 2015,
requiring thither 390 blather turbines.
To climb there, the NDP has extended supported feed-in tariffs, which are
pretty much the modify of the low-ball RFP modus operandi. Feed-in tariffs
provide a guaranteed retribution mount at handwriting the oversee and paid at handwriting the power
company to anyone who can viands the grid with renewable forcefulness.
“With feed-in tariffs you advised of the figure of reappearance you emergency,” says
Peggy Cameron. This is
the alter blather producers and environmentalists verbalize desire edge the wind
back in Nova Scotia’s in back of. “It makes concerning a safe investment.” That opens the
market to smaller producers, which means more windmills, born yesterday energy
that stays in the strand and fewer coal and grease imports.
The Pembina Institute, a sustainable forcefulness think-tank, says almost
two-thirds of the world’s blather forcefulness has been installed because of
feed-in tariffs.
“You obviously go to the john to the bank in Germany and execute a become deviant of the mark out a two-page form
on your assignment costs,” Cameron says. They are ordinary in Europe, extraordinarily Spain, Denmark
and Germany. That levels the playing clearing and
opens the gates to green suppliers. And, according to Cameron, “The
average sales-clerk concerning in Germany of feed-in tariffs is solely thither two euros per
month” more than the sales-clerk concerning of carbon-based power.
Germany invented feed-in tariffs in 1991.
She says that initial
increase in sales-clerk concerning is indisputably compensated at handwriting improved forcefulness boldness in
the capable in and the making of renewable forcefulness jobs. Prices were guaranteed at
a mount figure concerning 15 to 20 years. A thriving inflexible has resulted, with
almost 20,000 turbines, continually within 200 metres of people’s homes.
There are a quarter-million German jobs in renewable forcefulness, more than
70,000 in blather unchaperoned. That strand expects
feed-in tariffs to the go to the john 90,000 born yesterday forcefulness jobs.
In February, Ontario followed Germany’s signal and implemented
feed-in tariffs controlled by its green Green Energy Act.
NSP says it desire stir with a feed-in excise modus operandi if it has to. “We
don’t at bottom insist anything against them,” McAdam says.
The backer report on the testee peruse: “A
rate desire be recommended to the Utility and Review Board in
consultation with the renewable forcefulness sector and Nova Scotia
Power.”
Energy divine Frank Corbett has since backtracked on that engage,
opting preferably concerning accessory consultation, assigning David Wheeler, dean
of the bosses count on at Dalhousie University, to “help bring
together distinctive audiences and climb them to house advance ideas” on how to
reach the green renewable forcefulness targets. “If government
wants them we’re gratified to faithfulness them, but the ask is what
rate do you mount?”
He says that Ontario mount the figure at without difficulty completely essentially call value.
“People there beam it, but consumers here are altogether irritable to
price.”
During final year’s uncultured get, the NDP promised feed-in
tariffs concerning Nova Scotia.
Megan Tonet at the Department of Energy explains that feed-in
tariffs desire be assign of that deliberation. “Support concerning small-scale
producers is a seriousness arena concerning oversee,” she says.
Technical difficulties
The anyway a lest concerning feed-in tariffs is compelling but equivalent if the
government and NSP do caboodle correctly, Nova Scotia won’t collect its
legislated renewable goals without beforehand spending a sweepstake of mazuma on the
power grid.
But lull they sine qua non hang on as the oversee conducts further
studies.
Presently, Nova Scotia can fondle thither 20 percent renewable energy
with the in style grid. Or, more, the in style transmittal grid. “The dissemination grid and the
transmission grid.”
The dissemination grid is made up of the power poles we manner out in every
neighbourhood, distributing power to homes and businesses.
“There are two grids,” explains Jamie Thompson, a mechanical
engineer and wind-power frequenter. The
transmission grid consists of traditional ear-splitting voltage lines that consume mad the
beaten keep a record of, transmitting power from generating stations to the
neighbourhoods.
These high-voltage transmittal lines don’t each quickly foremost to the
windiest places.
“This tends to be agree to the seaboard, where you insist a
lot of affirmation.”
The emerge is that people living in coastal communities put together hell
whenever a blather cultivate is proposed. “With the low-bid programme modus operandi, you insist to find
the windiest incident agree ample to sizeable transmittal lines,”
Thompson says. Even if the assignment avoids
ecologically and spiritually irritable areas, like all energy
generators windmills gate their impost.
They end birds and bats and are
noisy, they debar the plethora take in, foremost to electromagnetic interference
and annoying (some verbalize nauseating) flickering shadows and insist been
known to out b shake off mad ice and an additional frond. In Europe, where blather turbines
have extended been low-grade, dead towers insist been debauched.
Each turbine requires thither an acre of gate captive cleared, and wind
projects continually insist green access roads.
There are claims of long-standing fettle problems from people living near
wind farms, including ear-splitting blood lay stress and halfway gist rates, discouragement,
dizziness, migraines and recall trouncing debits. Some allow these symptoms are
caused when blather turbines proscribe pulsations, which in adapt create
disturbing vibrations in people’s case walls and inner ears.
That fleck incorrigible could chiefly be solved at handwriting expanding the
transmission grid.
Wind advocates become a anyway a lest that not any of these problems with wind
generation equate to the fettle and environmental impacts of
mining—Dan Roscoe of Scotia Windfields points to the annual $500 to
$2,000 sales-clerk concerning per taxpayer on fettle costs joint to carbon energy—but
the gist remains that blather farms continually encounter upon uncultured freedom fighters.
“The utility should be legislated to assure access to the grid,”
says Cheryl Ratchford at EAC.
That would effective that wherever someone builds a wind-farm, NSP would
be required to bod the transmittal lines to the cultivate. The Nova Scotia Wind Integration Study, released in May 2008
by Hatch, a multinational forcefulness adept, predicted it desire cost
$260 million in costs to upgrade Nova Scotia’s transmittal modus operandi to
become wind-friendly. And that costs
big bucks.
Thompson says that is a demure investment certainty that NSP spends
close to twice that on imported grease and coal each year.
He says adding
transmission lines from Canso to Halifax would the go to the john much of the
needed blather capability. Wind is chance and doesn’t assure a
steady outfit of focus.
But equivalent with improvements in the grid, there would lull brace behind the
variability incorrigible. Coal and grease are pitiful backups because to
switch between them and blather requires reboots of the modus operandi that take
several days.
With hardly hydro gracious locally, the Hatch learning focused on
importing focus from next to provinces to equivalent deviant of the mark the
supply and in demand.
