It's just as well that the Ontario Legislature added an aboriginal prayer to its proceedings that beseeched the Great Spirit for "your wisdom and your strength," because the government is soon going to test the patience of everyone in the province.

The selection of the Darlington nuclear generation station as the site of two new reactors moves this whole nuclear adventure one more step past the theoretical and nearer to the point where we know what it will cost. But even at this point it's a near certainty that the renewed program is going to be much more expensive than originally forecast, which would throw an element of confusion into Ontario's electricity system and threaten its economic health.

This is a speculation, of course. Now, we know only where the new reactors - the first since the original Darlington units went into service in 1993 - will be. We don't know the technology to be used - the Candu of Atomic Energy of Canada Ltd. or the designs of Areva NP or Westinghouse Electric Co. - but we will by the end of the year.

What we won't know for a very long while is how much this whole endeavour is going to cost. For now, that's good news for the government because few voters are going to like what they find out. Indeed, skepticism about nukes has been ingrained in Ontarians ever since the original Darlington plants opened a decade late and three times over initial cost estimates.

Energy Minister Gerry Phillips is right when he says that the cost overruns were mostly caused by a stop-start construction program. He hopes that fierce bidding among AECL, Areva and Westinghouse will keep costs down.

But there is a limit to what the firms can do as the costs of commodities, labour and high-tech fabrications soar.

When the government first received advice in 2005 about its power-supply system, the Ontario Power Authority was assuming nuclear construction costs of $2,600 per kilowatt or $2.6-billion for a 1,000-megawatt reactor. It is to dream. Now, a U.S. industry group, the Washington-based Nuclear Energy Institute, is saying that the figure is at least $3,500 per kilowatt and this might even be a low ball.

Last fall, for example, Moody's Investors Service said new reactors could cost as much as $6,000 per kilowatt. The company said this was "only marginally better than a guess," but this spring, Florida Light and Power proposed building new units at a cost of up to $8,000 per kilowatt or $12-billion per reactor.

"We are shocked at the magnitude of the escalation," said David Kraft, director of the Nuclear Energy Information Service, an anti-nuclear group in Chicago. He cited the cost of construction materials such as copper, steel and concrete as one reason for the surge in costs, but noted as well that the 20-year moratorium on construction has forced the industry to reinvent the specialized techniques that nuclear fission requires. Nuclear Energy Institute spokesman Steve Kerekes agreed that commodity prices "are up pretty substantially."

The government has been advised by the Ontario Power Authority that a $26-billion investment over 20 years will allow the construction of new reactors and the refurbishment of old ones to ensure that nuclear generation continues to provide about half the province's electricity. But if, as seems likely, the new Darlington reactors eat up a huge chunk of that budget, the question is where the money will come from to refurbish or replace the aged Pickering reactors or other projects not yet dreamed of.

"We are weak, we are small," says the Ojibwa prayer recited in the legislature. "We need your wisdom and strength."

Wise words, indeed.

How Alberta’s lithium-laced oil fields can fuel the electric vehicle revolution

Alberta Lithium Brine can power EV batteries via direct lithium extraction, leveraging oilfield infrastructure and critical minerals policy to build a low-carbon supply chain with clean energy, lower emissions, and domestic manufacturing advantages.

 

Key Points

Alberta lithium brine is subsurface saline water rich in lithium, extracted via DLE to supply EV batteries.

✅ Uses direct lithium extraction from oilfield brines

✅ Leverages Alberta infrastructure and skilled workforce

✅ Supports EV battery supply chain with lower emissions

 

After a most difficult several months, Canadians are cautiously emerging from their COVID-19 isolation and confronting a struggling economy.
There’s a growing consensus that we need to build back better from COVID-19, and to position for the U.S. auto sector’s pivot to electric vehicles as supply chains evolve. Instead of shoring up the old economy as we did following the 2008 financial crisis, we need to make strategic investments today that will prepare Canada for tomorrow’s economy.

Tomorrow’s energy system will look very different from today’s — and that tomorrow is coming quickly. The assets of today’s energy economy can help build and launch the new industries required for a low-carbon future. And few opportunities are more intriguing than the growing lithium market.

The world needs lithium – and Alberta has plenty

It’s estimated that three billion tonnes of metals will be required to generate clean energy by 2050. One of those key metals – lithium, a light, highly conductive metal – is critical to the construction of battery electric vehicles (BEV). As global automobile manufacturers design hundreds of new BEVs, demand for lithium is expected to triple in the next five years alone, a trend sharpened by pandemic-related supply risks for automakers.

Most lithium today originates from either hard rock or salt flats in Australia and South America. Alberta’s oil fields hold abundant deposits of lithium in subsurface brine, but so far it’s been overlooked as industrial waste. With new processing technologies and growing concerns about the security of global supplies, this is set to change. In January, Canada and the U.S. finalized a Joint Action Plan on Critical Minerals to ensure supply security for critical minerals such as lithium and to promote supply chains closer to home, aligning with U.S. efforts to secure EV metals among allies worldwide.

This presents a major opportunity for Canada and Alberta. Lithium brine will be produced much like the oil that came before it. This lithium originates from many of the same reservoirs responsible for driving both Alberta’s economy and the broader transportation fuel sector for decades. The province now has extensive geological data and abundant infrastructure, including roads, power lines, rail and well sites. Most importantly, Alberta has a highly trained workforce. With very little retooling, the province could deliver significant volumes of newly strategic lithium.

Specialized technologies known as direct lithium extraction, or DLE, are being developed to unlock lithium-brine resources like those in Canada. In Alberta, E3 Metals* has formed a development partnership with U.S. lithium heavyweight Livent Corporation to advance and pilot its DLE technology. Prairie Lithium and LiEP Energy formed a joint venture to pilot lithium extraction in Saskatchewan. And Vancouver’s Standard Lithium is already piloting its own DLE process in southern Arkansas, where the geology is very similar to Alberta and Saskatchewan.

Heavy on quality, light on emissions

All lithium produced today has a carbon footprint, most of which can be tied back to energy-intensive processing. The purity of lithium is essential to battery safety and performance, but this comes at a cost when lithium is mined with trucks and shovels and then refined in coal-heavy China.

As automakers look to source more sustainable raw materials, battery recycling will complement responsible extraction, and Alberta’s experience with green technologies such as renewable electricity and carbon capture and storage can make it one of the world’s largest suppliers of zero-carbon lithium.

Beyond raw materials

The rewards would be considerable. E3 Metals’ Alberta project alone could generate annual revenues of US$1.8 billion by 2030, based on projected production and price forecasts. This would create thousands of direct jobs, as initiatives like a lithium-battery workforce initiative expand training, and many more indirectly.

To truly grow this industry, however, Canada needs to move beyond its comfort zone. Rather than produce lithium as yet another raw-commodity export, Canadians should be manufacturing end products, such as batteries, for the electrified economy, with recent EV assembly deals underscoring Canada’s momentum. With nickel and cobalt refining, graphite resources and abundant petrochemical infrastructure already in place, Canada must aim for a larger piece of the supply chain.

By 2030, the global battery market is expected to be worth $116 billion annually. The timing is right to invest in a strategic commodity and grow our manufacturing sector. This is why the Alberta-based Energy Futures Lab has called lithium one of the ‘Five big ideas for Alberta’s economic recovery.’  The assets of today’s energy economy can be used to help build and launch new resource industries like lithium, required for the low-carbon energy system of the future.

Industry needs support

To do this, however, governments will have to step up the way they did a generation ago. In 1975, the Alberta government kick-started oil-sands development by funding the Alberta Oil Sands Technology and Research Authority. AOSTRA developed a technology called SAGD (steam-assisted gravity drainage) that now accounts for 80% of Alberta’s in situ oil-sands production.

Canada’s lithium industry needs similar support. Despite the compelling long-term economics of lithium, some industry investors need help to balance the risks of pioneering such a new industry in Canada. The U.S. government has recognized a similar need, with the Department of Energy’s recent US$30 million earmarked for innovation in critical minerals processing and the California Energy Commission’s recent grants of US$7.8 million for geothermal-related lithium extraction.

To accelerate lithium development in Canada, this kind of leadership is needed. Government-assisted financing could help early-stage lithium-extraction technologies kick-start a whole new industry.

Aspiring lithium producers are also looking for government’s help to repurpose inactive oil and gas wells. The federal government has earmarked $1 billion for cleaning up inactive Alberta oil wells. Allocating a small percentage of that total for repurposing wells could help transform environmental liabilities into valuable clean-energy assets.

The North American lithium-battery supply chain will soon be looking for local sources of supply, and there is room for Canada-U.S. collaboration as companies turn to electric cars, strengthening regional resilience.

Rolls-Royce expecting UK approval for mini nuclear reactor by mid-2024

Rolls-Royce SMR UK Approval underscores nuclear innovation as regulators review a 470 MW factory-built modular reactor, aiming for grid power by 2029 to boost energy security, cut fossil fuels, and accelerate decarbonization.

 

Key Points

UK regulatory clearance for Rolls-Royce's 470 MW modular reactor, targeting grid power by 2029 to support clean energy.

✅ UK design approval expected by mid 2024

✅ First 470 MW unit aims for grid power by 2029

✅ Modular, factory-built; est. £1.8b per 10-acre site

 

A Rolls-Royce (RR.L) design for a small modular nuclear reactor (SMR) will likely receive UK regulatory approval by mid-2024, reflecting progress seen in the US NRC safety evaluation for NuScale as a regulatory benchmark, and be able to produce grid power by 2029, Paul Stein, chairman of Rolls-Royce Small Modular Reactors.

The British government asked its nuclear regulator to start the approval process in March, in line with the UK's green industrial revolution agenda, having backed Rolls-Royce’s $546 million funding round in November to develop the country’s first SMR reactor.

Policymakers hope SMRs will help cut dependence on fossil fuels and lower carbon emissions, as projects like Ontario's first SMR move ahead in Canada, showing momentum.

Speaking to Reuters in an interview conducted virtually, Stein said the regulatory “process has been kicked off, amid broader moves such as a Canadian SMR initiative to coordinate development, and will likely be complete in the middle of 2024.

“We are trying to work with the UK Government, and others to get going now placing orders, echoing expansions like Darlington SMR plans in Ontario, so we can get power on grid by 2029.”

In the meantime, Rolls-Royce will start manufacturing parts of the design that are most unlikely to change, while advancing partnerships like a MoU with Exelon to support deployment, Stein added.

Each 470 megawatt (MW) SMR unit costs 1.8 billion pounds ($2.34 billion) and would be built on a 10-acre site, the size of around 10 football fields, though projects in New Brunswick SMR debate have prompted questions about costs and timelines.

Unlike traditional reactors, SMRs are cheaper and quicker to build and can also be deployed on ships and aircraft. Their “modular” format means they can be shipped by container from the factory and installed relatively quickly on any proposed site.

Report: Solar ITC Extension Would Be ‘Devastating’ for US Wind Market

Solar ITC Impact on U.S. Wind frames how a 30% solar investment tax credit could undercut wind PTC economics, shift corporate procurement, and, without transmission and storage, slow onshore builds despite offshore wind momentum.

 

Key Points

It is how a solar ITC extension may curb U.S. wind growth absent PTC parity, transmission, storage, and offshore backing.

✅ ITC at 30% risks shifting corporate procurement to solar.

✅ Post-PTC wind faces grid, transmission, and curtailment headwinds.

✅ Offshore wind, storage pairing, TOU demand could offset.

 

The booming U.S. wind industry, amid a wind power surge, faces an uncertain future in the 2020s. Few factors are more important than the fate of the solar ITC.

An extension of the solar investment tax credit (ITC) at its 30 percent value would be “devastating” to the future U.S. wind market, according to a new Wood Mackenzie report.

The U.S. is on track to add a record 14.6 gigawatts of new wind capacity in 2020, despite Covid-19 impacts, and nearly 39 gigawatts during a three-year installation boom from 2019 to 2021, according to Wood Mackenzie’s 2019 North America Wind Power Outlook.

But the market’s trajectory begins to look highly uncertain from the early 2020s onward, and solar is one of the main reasons why.

Since the dawn of the modern American renewables market, the wind and solar sectors have largely been allies on the national stage, benefiting from many of the same favorable government plans and sharing big-picture goals. Until recently, wind and solar companies rarely found themselves in direct competition.

But the picture is changing as solar catches up to wind on cost and the grid penetration of renewables surges. What was once a vague alliance between the two fastest growing renewables technologies could morph into a serious rivalry.

While many project developers are now active in both sectors, including NextEra Energy Resources, Invenergy and EDF, the country’s thriving base of wind manufacturers could face tougher days ahead.

 

The ITC's inherent advantage

At this point, wind remains solar’s bigger sibling in many ways.

The U.S. has nearly 100 gigawatts of installed wind capacity today, compared to around 67 gigawatts of solar. With their substantially higher capacity factors, wind farms generated four times more power for the U.S. grid last year than utility-scale solar plants, for a combined wind-solar share of 8.2 percent, according to government figures, even as renewables are projected to reach one-fourth of U.S. electricity generation. (Distributed PV systems further add to solar’s contribution.)

But it's long been clear that wind would lose its edge at some point. The annual solar market now regularly tops wind. The cost of solar energy is falling more rapidly, and appears to have more runway for further reduction. Solar’s inherent generation pattern is more valuable in many markets, delivering power during peak-demand hours, while the wind often blows strongest at night.

 

And then there’s the matter of the solar ITC.

In 2015, both wind and solar secured historic multi-year extensions to their main federal subsidies. The extensions gave both industries the longest period of policy clarity they’ve ever enjoyed, setting in motion a tidal wave of installations set to crest over the next few years.

Even back in 2015, however, it was clear that solar got the better deal in Washington, D.C.

While the wind production tax credit (PTC) began phasing down for new projects almost immediately, solar developers were given until the end of 2019 to qualify projects for the full ITC.

And critically, while the wind PTC drops to nothing after its sunset, commercially owned solar projects will remain eligible for a 10 percent ITC forever, based on the existing legislation. Over time, that amounts to a huge advantage for solar.

In another twist, the solar industry is now openly fighting for an extension of the 30 percent ITC, while the wind industry seemingly remains cooler on the prospect of pushing for a similar prolongation — having said the current PTC extension would be the last.

 

Plenty of tailwinds, too

Wood Mackenzie's report catalogues multiple factors that could work for or against the wind market in the "uncharted" post-PTC years, many of them, including the Covid-19 crisis, beyond the industry’s direct control.

If things go well, annual installations could bounce back to near-record levels by 2027 after a mid-decade contraction, the report says. But if they go badly, installations could remain depressed at 4 gigawatts or below from 2022 through most of the coming decade, and that includes an anticipated uplift from the offshore market.

An extension of the solar ITC without additional wind support would “severely compound” the wind market’s struggle to rebound in the 2020s, the report says. The already-evident shift in corporate renewables procurement from wind to solar could intensify dramatically.

The other big challenge for wind in the 2020s is the lack of progress on transmission infrastructure that would connect potentially massive low-cost wind farms in interior states with bigger population centers. A hoped-for national infrastructure package that might address the issue has not materialized.

Even so, many in the wind business remain cautiously optimistic about the post-PTC years, with a wind jobs forecast bolstering sentiment, and developers continue to build out longer-term project pipelines.

Turbine technology continues to improve. And an extension of the solar ITC is far from assured.

Other factors that could work in wind’s favor in the years ahead include:

The nascent offshore sector, which despite lingering regulatory uncertainty at the federal level looks set to blossom into a multi-gigawatt annual market by the mid-2020s, in line with an offshore wind forecast that highlights substantial growth potential. Lobbying efforts for an offshore wind ITC extension are gearing up, offering a potential area for cooperation between wind and solar.

The potential linkage of policy support for energy storage to wind projects, building on the current linkage with solar.

Growing electric vehicle sales and a shift toward time-of-use retail electricity billing, which could boost power demand during off-peak hours when wind generation is strong.

The land-use advantages wind farms have over solar in some agricultural regions.

Next Offshore Wind in U.S. Can Compete With Gas, Developer Says

Offshore Wind Cost Competitiveness is rising as larger turbines boost megawatt output, cut LCOE, and trim maintenance and installation time, enabling projects in New England to rival natural gas pricing while scaling reliably.

 

Key Points

It describes how larger offshore turbines lower LCOE and O&M, making U.S. projects price competitive with natural gas.

✅ Larger turbines boost MW output and reduce LCOE.

✅ Lower O&M and faster installation cut lifecycle costs.

✅ Competes with gas in New England bids, per BNEF.

 

Massive offshore wind turbines keep getting bigger, as projects like the biggest UK offshore wind farm come online, and that’s helping make the power cheaper — to the point where developers say new projects in U.S. waters can compete with natural gas.

The price “is going to be a real eye-opener,” said Bryan Martin, chairman of Deepwater Wind LLC, which won an auction in May to build a 400-megawatt wind farm southeast of Rhode Island.

Deepwater built the only U.S. offshore wind farm, a 30-megawatt project that was completed south of Block Island in 2016. The company’s bid was selected by Rhode Island the same day that Massachusetts picked Vineyard Wind to build an 800-megawatt wind farm in the same area, while international investors such as Japanese utilities in UK projects signal growing confidence.

#google#

Bigger turbines that make more electricity have cut the cost per megawatt by about half, a trend aided by higher-than-expected wind potential in many markets, said Tom Harries, a wind analyst at Bloomberg New Energy Finance. That also reduces maintenance expenses and installation time. All of this is helping offshore wind vie with conventional power plants.

“You could not build a thermal gas plant in New England for the price of the wind bids in Massachusetts and Rhode Island,” Martin said Friday at the U.S. Offshore Wind Conference in Boston. “It’s very cost-effective for consumers.”

The Massachusetts project could be about $100 to $120 a megawatt hour, according to a February estimate from Harries, though recent UK price spikes during low wind highlight volatility. The actual prices there and in Rhode Island weren’t disclosed.

For comparison, a new U.S. combine-cycle gas turbine ranges from $40 to $60 a megawatt-hour, and a new coal plant is $67 to $113, according to BNEF data.

 

A new power plant in land-constrained New England would probably be higher than that, and during winter peaks the region has seen record oil-fired generation in New England that underscores reliability concerns. More importantly, gas plants get a significant portion of their revenue from being able to guarantee that power is always available, something wind farms can’t do, said William Nelson, a New York-based analyst with BNEF. Looking only at the price at which offshore turbines can deliver electricity is a “narrow mindset,” he said.

To Limit Climate Change, Scientists Try To Improve Solar And Wind Power

Wisconsin Solar and Wind Energy advances as rooftop solar, utility-scale farms, and NREL perovskite solar cells improve efficiency; wind turbines gain via wake modeling, yaw control, and grid-scale battery storage to cut carbon emissions.

 

Key Points

It is Wisconsin's growth in rooftop and utility-scale solar plus optimized wind turbines to cut carbon emissions.

✅ Perovskite solar cells promise higher efficiency, need longevity

✅ Wake modeling and yaw control optimize wind farm output

✅ Batteries and bids can offset reliance on natural gas

 

Solar energy in Wisconsin continued to grow in 2019, as more homeowners had rooftop panels installed and big utilities started building multi-panel solar farms.

Wind power is increasing more slowly in the state. However, renewable power developers are again coming forward with proposals for multiple turbines.

Nationally, researchers are working on ways to get even more energy from solar and wind, with the U.S. moving toward 30% electricity from wind and solar in coming years, as states like Wisconsin aim to reduce their carbon emissions over the next few decades.

One reason solar energy is growing in Wisconsin is due to the silicon panels becoming more efficient. But scientists haven't finished trying to improve panel efficiency. The National Renewable Energy Laboratory (NREL) in Golden, Col., is one of the research facilities experimenting with brushing a lab-made solution called perovskite onto a portion of a panel called a solar cell.

In a demonstration video supplied by NREL, senior scientist Maikel van Hest said that, in the lab anyway, the painted cell and its electrical connections called contacts, produce more energy:

"There you go! That's how you paint a perovskite solar cell. And you imagine that ultimately what you could do is you could see a company come in with a truck in front of your house and they would basically paint on the contacts first, dry those, and paint the perovskite over it. That you would have photovoltaic cells on the side of your house, put protective coating on it, and we're done."

Another NREL scientist, David Moore, says the new solar cells could be made faster and help meet what's expected to be a growing global demand for energy. However, Moore says the problem has been lack of stability.

"A solar cell with perovskites will last a couple years. We need to get that to 20-25 years, and that's the big forefront in perovskite research, is getting them to last longer," Moore told members of the Society of Environmental Journalists during a recent tour of NREL.

Another part of improving renewable energy is making wind turbines more productive. At NREL's Insight Center, a large screen showing energy model simulations dominates an otherwise darkened room. Visualization scientist Nicholas Brunhart-Lupo points to a display on the screen that shows how spinning turbines at one edge of a wind farm can cause an airflow called a wake, which curtails the power generation of other turbines.

"So what we find in these simulations is these four turbines back here, since they have this used air, this low-velocity wake being blown to their faces, they're only generating about 20% of the energy they should be generating," he explains.

Brunhart-Lupo says the simulations can help wind farm developers with placement of turbines as well as adjustments to the rotor and blades called the yaw system.

Continued progress with renewables may be vital to any state or national pledges to reduce use of fossil fuels and carbon emissions linked to climate change, including Biden's solar expansion plan as a potential pathway. Some scientists say to limit a rise in global temperature, there must be a big decline in emissions by 2050.

But even utilities that say they support use of more renewables, as why the grid isn't 100% renewable yet makes clear, aren't ready to let go of some energy sources. Jonathan Adelman of Xcel Energy, which serves part of Western Wisconsin, says Xcel is on track to close its last two coal-fired power plants in Minnesota. But he says the company will need more natural gas plants, even though they wouldn't run as often.

"It's not perfect. And it is in conflict with our ultimate goal of being carbon-free," says Adelman. "But if we want to facilitate the transition, we still need resources to help that happen."

Some in the solar industry would like utilities that say they need more natural gas plants to put out competitive bids to see what else might be possible. Solar advocates also note that in some states, energy regulators still favor the utilities.

Meanwhile, solar slowly marches ahead, including here in southeastern Wisconsin, as Germany's solar power boost underscores global momentum.

On the roof of a ranch-style home in River Hills, a work crew from the major solar firm Sunrun recently installed mounting brackets for solar panels.

Sunrun Public Policy Director Amy Heart says she supports research into more efficient renewables. But she says another innovation may have to come in the way regulators think.

"Instead of allowing and thinking about from the perspective of the utility builds the power plant, they replace one plant with another one, they invest in the infrastructure; is really thinking about how can these distributed solutions like rooftop solar, peer-to-peer energy sharing, and especially rooftop solar paired with batteries how can that actually reduce some of what the utility needs?

Large-scale energy storage batteries are already being used in some limited cases. But energy researchers continue to make improvements to them, too, with cheap solar batteries beginning to make widespread adoption more feasible as scientists race to reduce the expected additional harm of climate change.

Hydro once made up around half of Alberta's power capacity. Why does Alberta have so little now?

Alberta Hydropower Potential highlights renewable energy, dams, reservoirs, grid flexibility, contrasting wind and solar growth with limited investment, regulatory hurdles, river basin resources, and decarbonization pathways across Athabasca, Peace, and Slave River systems.

 

Key Points

It is the technical capacity for new hydro in Alberta's river basins to support a more reliable, lower carbon grid.

✅ 42,000 GWh per year developable hydro identified in studies.

✅ Major potential in Athabasca, Peace, and Slave River basins.

✅ Barriers include high capital costs, market design, water rights.

 

When you think about renewable energy sources on the Prairies, your mind may go to the wind farms in southern Alberta, or even the Travers Solar Project, southeast of Calgary.

Most of the conversation around renewable energy in the province is dominated by advancements in solar and wind power, amid Alberta's renewable energy surge that continues to attract attention. 

But what about Canada's main source of electricity — hydro power?

More than half of Canada's electricity is generated from hydro sources, with 632.2 terawatt-hours produced as of 2019. That makes it the fourth largest installed capacity of hydropower in the world. 

But in Alberta, it's a different story. 

Currently, hydro power contributes between three and five per cent of Alberta's energy mix, while fossil fuels make up about 89 per cent.

According to Canada's Energy Future report from the Canada Energy Regulator, by 2050 it will make up two per cent of the province's electricity generation shares.

So why is it that a province so rich in mountains and rivers has so little hydro power?


Hydro's history in Alberta
Hydro power didn't always make up such a small sliver of Alberta's electricity generation. Hydro installations began in the early 20th century as the province's population exploded. 

Grant Berg looks after engineering for hydro for TransAlta, Alberta's largest producer of hydro power with 17 facilities across the province.

"Our first plant was Horseshoe, which started in 1911 that we formed as Calgary Power," he said. 

"It was really in response to the City of Calgary growing and having some power needs."

Berg said in 1913, TransAlta's second installation, the Kananaskis Plant, started as Calgary continued to grow.

Some bigger installations were built in the 1920s, including Ghost reservoir, but by mid-century population growth increased.

"Quite a large build out really, I think in response to the growth in Alberta following the war. So through the 1950s really quite a large build out of hydro from there."

By the 1950s, around half of the province's installed capacity was hydro power.

"Definitely Calgary power was all hydro until the 1950s," said Berg. 


Hydro potential in the province 
Despite the current low numbers in hydroelectricity, Alberta does have potential. 

According to a 2010 study, there is approximately 42,000 gigawatt-hours per year of remaining developable hydroelectric energy potential at identified sites. 

An average home in Alberta uses around 7,200 kilowatt-hours of electricity per year, meaning that the hydro potential could power 5.8 million homes each year. 

"This volume of energy could be sufficient to serve a significant amount of Alberta's load and therefore play a meaningful role in the decarbonization of the province's electric system," the Alberta Electric System Operator said in its 2022 Pathways to Net-Zero Emissions report.

Much of that potential lies in northern Alberta, in the Athabasca, Peace and Slave River basins.

The AESO report says that despite the large resource potential, Alberta's energy-only market framework has attracted limited investment in hydroelectric generation. 

Hydro power was once a big deal in Alberta, but investment in the industry has been in decline since the 1950s. Climate change reporter Christy Climenhaga explains why.
So why does Alberta leave out such a large resource potential on the path to net zero?

The government of Alberta responded to that question in a statement. 

"Hydro facilities, particularly large scale ones involving dams, are associated with high costs and logistical demands," said the Ministry of Affordability and Utilities. 

"Downstream water rights for other uses, such as irrigation, further complicate the development of hydro projects."

The ministry went on to say that wind and solar projects have increased far more rapidly because they can be developed at relatively lower cost and shorter timelines, and with fewer logistical demands.

"Sources from wind power and solar are increasingly more competitive," said Jean-Denis Charlebois, chief economist with the Canadian Energy Regulator. 


Hydro on the path to net zero
Hydro power is incredibly important to Canada's grid, and will remain so, despite growth in wind and solar power across the province.

Charlebois said that across Canada, the energy make-up will depend on the province. 

"Canadian provinces will generate electricity in very different ways from coast to coast. The major drivers are essentially geography," he said. 

Charlebois says that in British Columbia, Manitoba, Quebec and Newfoundland and Labrador, hydropower generation will continue to make up the majority of the grid.

"In Alberta and Saskatchewan, we see a fair bit of potential for wind and solar expansion in the region, which is not necessarily the case on Canada's coastlines," he said.

And although hydro is renewable, it does bring its adverse effects to the environment — land use changes, changes in flow patterns, fish populations and ecosystems, which will have to be continually monitored. 

"You want to be able to manage downstream effects; make sure that you're doing all the proper things for the environment," said Ryan Braden, director of mining and hydro at TransAlta.

Braden said hydro power still has a part to play in Alberta, even with its smaller contributions to the future grid. 

"It's one of those things that, you know, the wind doesn't blow or the sun doesn't shine, this is here. The way we manage it, we can really support that supply and demand," he said.
