Twenty Arguments Against Building Site C Dam on the Peace River
by
Chris Aikman
Here Are Twenty Misleading and Erroneous Arguments Against Site C:
- "We don't need the electricity. Efficiency and conservation will reduce the need
for additional generation.”
This seems to imply that we don't
need additional electrical generation.
How then do we replace fossil energy, which still supplies four-fifths of our primary energy supply? Simply cutting back on our total primary energy supply will put us all back in the stone age.
- "Electrical demand in British Columbia has plateaued."
Sadly, this is true. Through its 'Power Smart' program, BC Hydro has has always campaigned to limit electrical use. The fact is that most of the changes they suggest to limit your electrical use actually increase your fossil fuel use. If you do the environmentally wise thing, and heat your dwelling with a heat pump, you will be immediately punished by a 50% increase in your hydro rate per kilowatt-hour as you move from Tier 1 to Tier 2 rates. BC Hydro's
Integrated Resource Plan (IRP) makes no real goal or consideration to displace fossil energy – which is our most urgent task!
It seems obvious that BC Hydro has been run for the benefit of the fossil fuel industry, rather than serving as the replacement for it.
BC Hydro needs to plan ahead of the market, and beyond provincial borders. It has
clearly not done this yet. In that sense, a new IRP is needed. Electrical energy has been depicted as the problem, while in fact it is the only viable solution to our energy & climate problems.
In BC, the Hydro rate policy, plus the lack of long-term planning, represent a political problem. They require a political solution. Unfortunately, no political party in BC is presently offering a solution.
- "It will create an immediate oversupply of electricity”.
Once again the myth of too much electricity is repeated. Electricity can displace fossil fuels for all building heating and operations: it can replace fossil fuels for most transportation purposes. These uses alone account for about two-thirds of our present carbon emissions. Solar/hydro-produced electricity will be cheap enough to displace fossil energy by market forces alone. No contrived taxes or regulation will be required for this transformation.
- "The electricity from Site C will only be used to process LNG, or to increase our fossil fuel extraction."
Well, the Christy Clark government really muddied the political waters with its plan to use Site C electricity to liquify natural gas. In that case, its energy would be entirely consumed in cooling natural gas to -160 Celsius in order to liquify it; that energy is 100% wasted and unrecoverable. Fortunately the mad schemes of politicians are no match for physical law and the realities of market economics. We all know that the massive LNG projects talked about will never happen in British Columbia. The power from Site C can be 100% used to displace fossil fuels from our primary energy supply.
- "Demand-side Management will solve the intermittency problem of sustainable energy."
It is impossible to make the case that demand-side management is
superior to supply-side management. The big advantage that fossil
energy has enjoyed is that it's there when you need it. Once
electricity is always there when you need it, its other advantages
(cost, ease of transmission, scalability, environmentally
cleanliness) will allow it to displace fossil power.
Demand-side management is simply not an issue when you have over two years
supply of water behind the W.A.C. Bennett dam. Doesn't it make more
sense to use this relatively unique advantage we have in BC? We can
deliver electrical power anytime, at a fixed rate. Other
jurisdictions can't. This is a huge advantage we should be using to
draw investment into our province.
Demand-side management is the reality faced by jurisdictions without a backup
power generation capacity. To put it very bluntly, demand-side
management is for losers.
- "Energy storage is a rapidly advancing field of research”
This suggests that some magic of chemistry or physics will somehow emerge to solve
intermittency of supply. That simply won't happen. The truth is
there is only one method of energy storage that is almost 100% efficient
and totally scalable: water at elevation. The technology we already
have is the best there ever will be. We need to expand stored
capacity if we are to make progress in sustainable use of energy.
- "Superbatteries will solve the energy storage problem."
We've been developing batteries for centuries. The limits of chemistry and chemical energy
storage should be pretty clear by now. Batteries typically require about fifty times the mass of fossil fuels to store the same amount of chemical energy.
There will be progress in
battery technology, but it won't be spectacular, and it is incapable of solving the energy storage problem on a societal scale.
- "Site C is a gigantic mega-project.”
Is there something wrong with that? Isn't it precisely megaprojects that make the plethora of smaller projects possible? This is especially true when it comes to the question of energy. It seems obvious our energy future requires a mix of large
and small facilities: the large enable the small to happen, wherever they are needed.
- "Gas-fired generation can solve the intermittency problem."
Yes, but you'll need a gigawatt of gas-fired generation for each gigawatt of wind or solar generation. That hardly leads to CO2 reduction and a climate solution.
- "Solar photovoltaic electricity is already cheaper, and getting cheaper everyday."
Yes, but solarPV cannot deliver a stand-alone solution, because the sun sets. In fact the spectacular
rise of solarPV puts increased urgency of the need for nighttime power generation that Site C could supply.
The cheaper solarPV power gets, the more we need Site C to complement it. That's the reality.
- "Wind generation will solve our electrical needs."
BC Hydro estimates that it can currently integrate 3,000 MW of wind
capacity onto its system”. This represents only 5% of generating capacity, so BC Hydro is effectively saying they will
limit wind generation to 5% of the electrical supply. Compare that
with what Denmark and Germany are already doing with wind: at times it suffices for all their electrical needs. With the ability to store power in reservoirs such as Site C, we essentially erase the limits to how much wind-generated electricity we can handle.
- "Geothermal electrical generation could supply all our energy needs."
This is almost certainly true. But so far, we do not have a single large-scale geothermal power plant in Canada to demonstrate that it can deliver energy in a cost-efficient manner. It's unrealistic to believe that geothermal can power Canada cost-efficiently when no proof-of-concept power station has yet been built in this country.
- "Treaty rights have been violated."
BC Hydro has consulted Treaty 8 and other First Nations groups for a decade, and some settlement of claim has been made. First nations'
rights are indeed important. They must be suitably consulted and
accommodated. But we do not grant an absolute veto to any citizen
group, aboriginal or otherwise, against the common good. Actually, optimization of the power system with its existing grid capacity from Treaty 8 lands offers these communities an incredible opportunity to lead the sustainability revolution with solarPV and wind generation from their lands.
The manageability of Site C's generation capacity is what makes the
those power sources viable in the first place.
The most-cost effective wind resource in BC is found in the Peace River region. First nations have
already become leaders in run-of-river and wind power projects. We can do this together.
As of February 2, 2017, 9 court cases have been heard on motions to stop Site C construction, mostly based on alleged treaty violations. The courts have rejected all 9 cases. Generally, courts in Canada have been staunch defenders of treaty rights.
- "The environmental impacts will be hugely negative."
We need to acknowledge that that the natural flow of the Peace
River has already been disrupted by the two existing power dams.
With a third dam and three reservoirs, there is far more freedom to
operate reservoir-to-reservoir release to produce more desirable
downstream effects, including a restoration of the natural river flow.
Site C potentially can have a very positive environmental impact.
- "Hydro dams consume so much water."
Hydro dams do not consume water: every drop is conserved: what goes in comes out. What the hydro generators do is harvest the gravitational energy of the water,
which was imparted to it by the sun, via the hydrologic cycle.
- "Reservoirs are huge sources of carbon dioxide and methane."
This statement is a total misrepresentation of the carbon cycle. Bodies of water do not create carbon dioxide or methane, but they can absorb, transport and release them. Biomass will create those gases with or without water reservoirs.
- "Hydroelectric dams and reservoirs are not clean sources of carbon-free energy."
Well, actually they are very clean and carbon-free. Their advantage is huge:
Lifecycle greenhouse gas emissions by electricity source
- "The flooded farmland could feed a million people."
This widely quoted claim has no quantitative basis. At present, only about one quarter of the land to be flooded at Site C is actually
under cultivation. Most of that farmland is used to grow animal fodder, not human food.
Agricultural productivity of the Peace River region is now limited by the extreme temperatures, which produce a very short growing season from last frost to first frost.
Large bodies of water do mitigate such temperature extremes. The Site C reservoir might actually increase agricultural productivity of the Peace region by moderating temperatures, and lengthening the growing season.
- "The soils in the valley are the best agricultural soils."
The valley contains a mix of soils; some are poor. Actually, the best agricultural soils in Canada would be found underwater on the bottoms of freshwater lakes and rivers that cover about 9% of Canada. No one is proposing that we drain all those bodies of water in order to farm them.
- "The Peace Valley is too precious and beautiful to flood."
It's one thing to argue against flooding valleys when the remaining
land is entirely rock and mountaintop. That is simply not the case in the deep soils east of the Rockies. There the surrounding terrain is all flat, rich, fertile agricultural land.
The Peace Valley is indeed beautiful. Yet, there will always remain hundreds of kilometers of the Peace Valley just as beautiful. There are many other beautiful rivers flowing from the Rockies onto the prairies. And remember, the lake formed by the new reservoir will be pretty awesome sight to behold.
A natural, market-driven solution to catastrophic climate change:
It has often been stated that in order to address the real and present dangers of climate change
from CO2, that we need to react in much the same way as did the
Allies at the outbreak of World War II. That is, we need to mobilize
all our efforts towards achieving a necessary goal. In 1939, the goal was the
preservation of freedom and democracy. Today it is the preservation of a stable climate environment on our planet.
Then as now there wasn't a perfect master plan of how the goal might be achieved. It just
requires a total commitment to get it done.
The climate war is truly underway. And we are losing.
What we need to do to stop catastrophic global warming is
simple enough: stop burning carbon! We do know there
will be huge intermittency problems as we eliminate fossil fuels, and
the only
large
scale solution to intermittency of supply will be water stored at
elevation (that is to say hydro reservoirs). In short we very much
will need Site C in any plausible scenario to eliminate our hydrocarbon dependence.
Note:
The original version of this paper was written in 2014.
Since then, it has become even more obvious that solar photovoltaic power, coupled with hydro storage, will provide the most viable solution to climate change.
They will provide the fastest, safest path to a more stable climate. The answer to the crisis is available right now.
