Coal, the dirtiest source of fuel, will remain the world's main source of power until 2030 and nuclear will lose market share, the International Energy Agency said.

Expectations of slower economic growth have led the IEA to downgrade its 2030 world electricity demand forecast to 23,141 terawatt hours (TWh), but the share of coal generated power would rise to 44 percent by 2015 from 41 percent in 2006.

It would stay at that level to 2030.

"Globally, coal-based electricity is projected to rise... to almost 14,600 TWh by 2030, giving rise to significant increases in associated CO2 emissions," the Paris-based agency said in its World Energy Outlook.

Most of the growth was expected in non-OECD countries, such as China, which the IEA expected soon to become the world's biggest electricity consumer. Its demand for power doubled between 2000 and 2006.

The IEA urged stronger policies for carbon capture and storage (CCS), saying the world was likely to make only a minor contribution in the period.

"Market mechanisms alone will not be sufficient to achieve the demonstration program on the scale required. Another challenge is financing the necessary CO2 transport infrastructure," it said.

Despite a global nuclear renaissance sparked by efforts to cut greenhouse gas emissions and mitigate climate change, the IEA expected nuclear's share in power generation to drop to 10 percent by 2030 from 15 percent in 2006.

"Over the past few years, a large number of countries have expressed renewed interest in building nuclear power plants," it said. "Few governments, however, have taken concrete steps to build new reactors."

As of the end of August, China topped the list of countries with nuclear power plants under construction, with 5,220 megawatts (MW), followed by India at 2,910 MW and Korea at 2,880 MW.

On a brighter note, the IEA predicted the share of renewable energy to rise to 23 percent by 2030 from 18 percent in 2006.

"Higher fossil fuel prices, increasing concerns over energy security and climate change are expected to encourage the development of renewable energy for electricity," the IEA said.

The agency said high prices would constrain growth in gas-fired generation, although it remained attractive due to lower capital costs and shorter construction time. Its market share was likely to fall slightly from 20 percent.

Looking into per capita electricity demand around the world, the IEA saw a gloomy outlook for some non-OECD countries, despite overall anticipated strong growth.

"A large number of people living there are not expected to have access to electricity even in 2030. India and Africa have the highest number of people in this category," it said.

Per capita electricity consumption in non-OECD countries was likely to rise to almost 2,400 kilowatt hours (kWh) by 2030, but the IEA saw it rising only to 671 kWh in Africa from 518. It would rise to 4,776 kWh in China from 1,788 in 2006.

Financial update from N.L energy corp. reflects pandemic's impact

Nalcor Energy Pandemic Loss underscores Muskrat Falls delays, hydroelectric risks, oil price shocks, and COVID-19 impacts, affecting ratepayers, provincial debt, timelines, and software commissioning for the Churchill River project and Atlantic Canada subsea transmission.

 

Key Points

A $171M Q1 2020 downturn linked to COVID-19, oil price collapse, and Muskrat Falls delays impacting schedules and costs.

✅ Q1 2020 profit swing: +$92M to -$171M amid oil price crash

✅ Muskrat Falls timeline slips; cost may reach $13.1B

✅ Software, workforce, COVID-19 constraints slow commissioning

 

Newfoundland and Labrador's Crown energy corporation reported a pandemic-related profit loss from the first quarter of 2020 on Tuesday, along with further complications to the beleaguered Muskrat Falls hydroelectric project.

Nalcor Energy recorded a profit loss of $171 million in the first quarter of 2020, down from a $92 million profit in the same period last year, due in part to falling oil prices during the COVID-19 pandemic.

The company released its financial statements for 2019 and the first quarter of 2020 on Tuesday, and officials discussed the numbers in a livestreamed presentation that detailed the impact of the global health crisis on the company's operations.

The loss in the first quarter was caused by lower profits from electricity sales and a drop in oil prices due to the pandemic and other global events, company officials said.

The novel coronavirus also added to the troubles plaguing the Muskrat Falls hydroelectric dam on Labrador's Churchill River, amid Quebec-N.L. energy tensions that long predate the pandemic.

Work at the remote site stopped in March over concerns about spreading the virus. Operations have been resuming slowly, with a reduced workforce tackling the remaining jobs.

Officials with Nalcor said it will likely be another year before the megaproject is complete.

CEO Stan Marshall estimates the months of delays could bring the total cost to $13.1 billion including financing, up from the previous estimate of $12.7 billion -- though the total impact of the coronavirus on the project's price tag has yet to be determined.

"If we're going to shut down again, all of that's wrong," Marshall said. "But otherwise, we can just carry on and we'll have a good idea of the productivity level. I'm hoping that by September we'll have a more definitive number here."

The 824 megawatt hydroelectric dam will eventually send power to Newfoundland, and later Nova Scotia, through subsea cables, even as Nova Scotia boosts wind and solar in its energy mix.

It has seen costs essentially double since it was approved in 2012, and faced significant delays even before pandemic-forced shutdowns in North America and around the world this spring.

Cost and schedule overruns were the subject of a sweeping inquiry that held hearings last year, while broader generation choices like biomass use have drawn scrutiny as well.

The commissioner's report faulted previous governments for failing to protect residents by proceeding with the project no matter what, and for placing trust in Nalcor executives who "frequently" concealed information about schedule, cost and related risks.

Some of the latest delays have come from challenges with the development of software required to run the transmission link between Labrador and Newfoundland, where winter reliability issues have been flagged in reports.

The software is still being worked out, Marshall said Tuesday, and the four units at the dam will come online gradually over the next year.

"It's not an all or nothing thing," Marshall said of the final work stages.
Nalcor's financial snapshot follows a bleak fiscal update from the province this month. The Liberal government reported a net debt of $14.2 billion and a deficit of more than $1.1 billion, even as a recent Churchill Falls deal promised new revenues for the province, citing challenges from pandemic-related closures and oil production shutdowns.

Finance Minister Tom Osborne said at the time that help from Ottawa will be necessary to get the province's finances back on track.

Muskrat Falls represents about one-third of the province's debt, and is set to produce more power than the province of about half a million people requires. Anticipated rate increases due to the ballooning costs and questions about Muskrat Falls benefits have posed a significant political challenge for the provincial government.

Ottawa has agreed to work with Newfoundland and Labrador on a rewrite of the project's financial structure, scrapping the format agreed upon in past federal-provincial loan agreements in order to ease the burden on ratepayers, while some argue independent planning would better safeguard ratepayers.

Marshall, a former Fortis CEO who was brought in to lead Nalcor in 2016, has called the project a "boondoggle" and committed to seeing it completed within four years. Though that plan has been disrupted by the pandemic, Marshall said the end is in sight.

"I'm looking forward to a year from now. And I hope to be gone," Marshall 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.

Europe's Worst Energy Nightmare Is Becoming Reality

European Energy Crisis shocks markets as Russia slashes gas via Nord Stream, spiking prices and triggering rationing, LNG imports, storage shortfalls, and emergency measures to secure energy security before a harsh winter.

 

Key Points

Europe-wide gas shock from reduced Russian flows drives price spikes, rationing risk, LNG reliance, and emergency action.

✅ Nord Stream cuts deepen supply insecurity and storage gaps

✅ LNG imports rise but terminal capacity and shipping are tight

✅ Policy tools: rationing, subsidies, demand response, coal restarts

 

As Russian gas cutoffs upend European energy security, the continent is struggling to cope with what experts say is one of its worst-ever energy crises—and it could still get much worse. 

For months, European leaders have been haunted by the prospect of losing Russia’s natural gas supply, which accounts for some 40 percent of European imports and has been a crucial energy lifeline for the continent. That nightmare is now becoming a painful reality as Moscow slashes its flows in retaliation for Europe’s support for Ukraine, dramatically increasing energy prices and forcing many countries to resort to emergency plans, including emergency measures to limit electricity prices in some cases, and as backup energy suppliers such as Norway and North Africa are failing to step up.

“This is the most extreme energy crisis that has ever occurred in Europe,” said Alex Munton, an expert on global gas markets at Rapidan Energy Group, a consultancy. “Europe [is] looking at the very real prospect of not having sufficient gas when it’s most needed, which is during the coldest part of the year.”

“Prices have shot through the roof,” added Munton, who noted that European natural gas prices—nearly $50 per MMBTu—have eclipsed U.S. price rises by nearly tenfold, and that rolling back electricity prices is tougher than it appears in the current market. “That is an extraordinarily high price to be paying for natural gas, and really there is no immediate way out from here.” 

Many officials and energy experts worry that the crisis will only deepen after Nord Stream 1, the largest gas pipeline from Russia to Europe, is taken down for scheduled maintenance this week. Although the pipeline is supposed to be under repair for only 10 days, the Kremlin’s history of energy blackmail and weaponization has stoked fears that Moscow won’t turn it back on—leaving heavily reliant European countries in the lurch. (Russia’s second pipeline to Germany, Nord Stream 2, was killed in February as Russian President Vladimir Putin prepared to invade Ukraine, leaving Nord Stream 1 as the biggest direct gas link between Russia and Europe’s biggest economy.)

“Everything is possible. Everything can happen,” German economy minister Robert Habeck told Deutschlandfunk on Saturday. “It could be that the gas flows again, maybe more than before. It can also be the case that nothing comes.”

That would spell trouble for the upcoming winter, when demand for energy surges and having sufficient natural gas is necessary for heating. European countries typically rely on the summer months to refill their gas storage facilities. And at a time of war, when the continent’s future gas supply is uncertain, having that energy cushion is especially crucial.

If Russia’s prolonged disruptions continue, experts warn of a difficult winter: one of potential rationing, industrial shutdowns, and even massive economic dislocation. British officials, who just a few months ago warned of soaring power bills for consumers, are now warning of even worse, despite a brief fall to pre-Ukraine war levels in gas prices earlier in the year.

Europe could face a “winter of discontent,” said Helima Croft, a managing director at RBC Capital Markets. “Rationing, industrial shut-ins—all of that is looming.”

Unrest has already been brewing, with strikes erupting across the continent as households struggle under the pressures of spiraling costs of living and inflationary pressures. Some of this discontent has also had knock-on effects in the energy market. In Norway, the European Union’s biggest supplier of natural gas after Russia, mass strikes in the oil and gas industries last week forced companies to shutter production, sending further shockwaves throughout Europe.

European countries are at risk of descending into “very, very strong conflict and strife because there is no energy,” Frans Timmermans, the vice president of the European Commission, told the Guardian. “Putin is using all the means he has to create strife in our societies, so we have to brace ourselves for a very difficult period.”

The pain of the crisis, however, is perhaps being felt most clearly in Germany, which has been forced to turn to a number of energy-saving measures, including rationing heated water and closing swimming pools. To cope with the crunch, Berlin has already entered the second phase of its three-stage emergency gas plan; last week, it also moved to bail out its energy giants amid German utility troubles that have been financially slammed by Russian cutoffs. 

But it’s not just Germany. “This is happening all across Europe,” said Olga Khakova, an expert on European energy security at the Atlantic Council, who noted that France has also announced plans to nationalize the EDF power company as it buckles under mounting economic losses, and the EU outlines gas price cap strategies to temper volatility. “The challenging part is how much can these governments provide in support to their energy consumers, to these companies? And what is that breaking point?”

The situation has also complicated many countries’ climate goals, even as some call it a wake-up call to ditch fossil fuels for Europe. In late June, Germany, Italy, Austria, and the Netherlands announced they would restart old coal power plants as they grapple with shrinking supplies. 

The potential outcomes that European nations are grappling with reveal how this crisis is occurring on a scale that has only been seen in times of war, Munton said. In the worst-case scenario, “we’re talking about rationing gas supplies, and this is not something that Europe has had to contend with in any other time than the wartime,” he said. “That’s essentially where things have got to now. This is an energy war.”

They also underscore the long and painful battle that Europe will continue to face in weaning itself off Russian gas. Despite the continent’s eagerness to leave Moscow’s supply behind, experts say Europe will likely remain trapped in this spiraling crisis until it can develop the infrastructure for greater energy independence—and that could take years. U.S. gas, shipped by tanker, is one option, but that requires new terminals to receive the gas and U.S. energy impacts remain a factor for policymakers. New pipelines take even longer to build—and there isn’t a surfeit of eligible suppliers.

Until then, European leaders will continue to scramble to secure enough supplies—and can only hope for mild weather. The “worst-case scenario is people having to choose between eating and heating come winter,” Croft said.

We Energies refiles rate hike request driven by rising nuclear power costs

We Energies rate increase driven by nuclear energy costs at Point Beach, Wisconsin PSC filings, and rising utility rates, affecting electricity prices for residential, commercial, and industrial customers while supporting WEC carbon reduction goals.

 

Key Points

A 2021 utility rate hike to recover Point Beach nuclear costs, modestly raising Wisconsin electricity bills.

✅ Residential bills rise about $0.73 per month

✅ Driven by $55.82/MWh Point Beach contract price

✅ PSC review and consumer advocates assessing alternatives

 

Wisconsin's largest utility company is again asking regulators to raise rates to pay for the rising cost of nuclear energy.

We Energies says it needs to collect an additional $26.5 million next year, an increase of about 3.4%.

For residential customers, that would translate to about 73 cents more per month, or an increase of about 0.7%, while some nearby states face steeper winter rate hikes according to regulators. Commercial and industrial customers would see an increase of 1% to 1.5%, according to documents filed with the Public Service Commission.

If approved, it would be the second rate increase in as many years for about 1.1 million We Energies customers, who saw a roughly 0.7% increase in 2020 after four years of no change, while Manitoba Hydro rate increase has been scaled back for next year, highlighting regional contrasts.

We Energies' sister utility, Wisconsin Public Service Corp., has requested a 0.13% increase, which would add about 8 cents to the average monthly residential bill, which went up 1.6% this year.

We Energies said a rate increase is needed to cover the cost of electricity purchased from the Point Beach nuclear power plant, which according to filings with the Securities Exchange Commission will be $55.82 per megawatt-hour next year.

So far this year, the average wholesale price of electricity in the Midwestern market was a little more than $25.50 per megawatt-hour, and recent capacity market payouts on the largest U.S. grid have fallen sharply, reflecting broader market conditions.

Owned and operated by NextEra Energy Resources, the 1,200-megawatt Point Beach Nuclear Plant is Wisconsin's last operational reactor. We Energies sold the plant for $924 million in 2007 and entered into a contract to purchase its output for the next two decades.

Brendan Conway, a spokesman for WEC Energy Group, said customers have benefited from the sale of the plant, which will supply more than a third of We Energies' demand and is a key component in WEC's strategy to cut 80% of its carbon emissions by 2050, amid broader electrification trends nationwide.

"Without the Point Beach plant, carbon emissions in Wisconsin would be significantly higher," Conway said.

As part of negotiations on its last rate case, WEC agreed to work with consumer advocates and the PSC to review alternatives to the contracted price increases, which were structured to begin rising steeply in 2018.

Tom Content, executive director of the Citizens Utility Board, said the contract will be an issue for We Energies customers into the next decade

"It's a significant source (of energy) for the entire state," Content said. "But nuclear is not cheap."

WEC filed the rate requests Monday, one week after the withdrawing similar applications. Conway said the largely unchanged filings had "undergone additional review by senior management."

WEC last week raised its second quarter profit forecast to 67 to 69 cents per share, up from the previous range of 58 to 62 cents per share.

The company credited better than expected sales in April and May along with operational cost savings and higher authorized profit margin for American Transmission Company, of which WEC is the majority owner.

Wisconsin's other investor-owned utilities have reported lower than expected fuel costs for 2020 and 2021, even as emergency fuel stock programs in New England are expected to cost millions this year.

Alliant Energy has proposed using about $31 million in fuel savings to help freeze rates in 2021, aligning with its carbon-neutral electricity plans as it rolls out long-term strategy, while Xcel Energy is proposing to lower its rates by 0.8% next year and refund its customers about $9.7 million in fuel costs for this year.

Madison Gas and Electric is negotiating a two-year rate structure with consumer groups who are optimistic that fuel savings can help prevent or offset rate increases, though some utilities are exploring higher minimum charges for low-usage customers to recover fixed costs.

Blood Nickel and Canada's Role in Global Mining Sustainability

Blood Nickel spotlights ethical sourcing in the EV supply chain, linking nickel mining to human rights, environmental impact, ESG standards, and Canadian leadership in sustainable extraction, transparency, and community engagement across global battery materials markets.

 

Key Points

Blood Nickel is nickel mined under unethical or harmful conditions, raising ESG, human rights, and environmental risks.

✅ Links EV battery supply chains to social and environmental harm

✅ Calls for transparency, traceability, and ethical sourcing standards

✅ Highlights Canada's role in sustainable mining and community benefits

 

The rise of electric vehicles (EVs) has sparked a surge in demand for essential battery components, particularly nickel, and related cobalt market pressures essential for their batteries. This demand has ignited concerns about the environmental and social impacts of nickel mining, particularly in regions where standards may not meet global sustainability benchmarks. This article explores the concept of "blood nickel," its implications for the environment and communities, and Canada's potential role in promoting sustainable mining practices.

The Global Nickel Boom

As the automotive industry shifts towards electric vehicles, nickel has emerged as a critical component for lithium-ion batteries due to its ability to store energy efficiently. This surge in demand has led to a global scramble for nickel, with major producers ramping up extraction efforts to meet market needs amid EV shortages and wait times that underscore supply constraints. However, this rapid expansion has raised alarms about the environmental consequences of nickel mining, including deforestation, water pollution, and carbon emissions from energy-intensive extraction processes.

Social Impacts: The Issue of "Blood Nickel"

Beyond environmental concerns, the term "blood nickel" has emerged to describe nickel mined under conditions that exploit workers, disregard human rights, or fail to uphold ethical labor standards. In some regions, nickel mining has been linked to issues such as child labor, unsafe working conditions, and displacement of indigenous communities. This has prompted calls for greater transparency and accountability in global supply chains, with initiatives like U.S.-ally efforts to secure EV metals aiming to align sourcing standards, to ensure that the benefits of EV production do not come at the expense of vulnerable populations.

Canada's Position and Potential

Canada, home to significant nickel deposits, stands at a pivotal juncture in the global EV revolution, supported by EV assembly deals in Canada that strengthen domestic manufacturing. With its robust regulatory framework, commitment to environmental stewardship, and advanced mining technologies, Canada has the potential to lead by example in sustainable nickel mining practices. Canadian companies are already exploring innovations such as cleaner extraction methods, renewable energy integration, and community engagement initiatives to minimize the environmental footprint and enhance social benefits of nickel mining.

Challenges and Opportunities

Despite Canada's potential, the mining industry faces challenges in balancing economic growth with environmental and social responsibility and building integrated supply chains, including downstream investments like a battery plant in Niagara that can connect materials to markets. Achieving sustainable mining practices requires collaboration among governments, industry stakeholders, and local communities to establish clear guidelines, monitor compliance, and invest in responsible resource development. This approach not only mitigates environmental impacts but also fosters long-term economic stability and social well-being in mining regions.

Pathways to Sustainability

Moving forward, Canada can play a pivotal role in shaping the global nickel supply chain by promoting transparency, ethical sourcing, and environmental stewardship. This includes advocating for international standards that prioritize sustainable mining practices, supporting research and development of cleaner technologies, and leveraging adjacent resources such as Alberta lithium potential to diversify battery supply chains, while fostering partnerships with global stakeholders to ensure a fair and equitable transition to a low-carbon economy.

Conclusion

The rapid growth of electric vehicles has propelled nickel into the spotlight, highlighting both its strategic importance and the challenges associated with its extraction. As global demand for "green" metals intensifies, addressing the concept of "blood nickel" becomes increasingly urgent, even as trade measures like tariffs on Chinese EVs continue to reshape market incentives. Canada, with its rich nickel reserves and commitment to sustainability, has an opportunity to lead the charge towards ethical and responsible mining practices. By leveraging its strengths in innovation, regulation, and community engagement, Canada can help forge a path towards a more sustainable future where electric vehicles drive progress without compromising environmental integrity or social justice.

Opinion: Now is the time for a western Canadian electricity grid

Western Canada Electric Grid could deliver interprovincial transmission, reliability, peak-load support, reserve sharing, and wind and solar integration, lowering costs versus new generation while respecting AESO markets and Crown utility structures.

 

Key Points

Interprovincial transmission to share reserves, boost reliability, integrate wind and solar, and cut peak capacity costs.

✅ Cuts reserve margins via diversity of peak loads

✅ Enables wind and solar balancing across provinces

✅ Saves ratepayers vs replacing retiring thermal plants

 

The 2017 Canadian Free Trade Agreement does not do much to encourage provinces to trade electric energy east and west. Would a western Canada electric grid help electricity consumers in the western provinces? Some Alberta officials feel that their electric utilities are investor owned and they perceive the Crown corporations of BC Hydro, SaskPower and Manitoba Hydro to be subsidized by their provincial governments, so an interprovincial electric energy trade would not be on a level playing field.

Because of the limited trade of electric energy between the western provinces, each utility maintains an excessive reserve of thermal and hydroelectric generation greater than their peak loads, to provide a reliable supply during peak load days as grids are increasingly exposed to harsh weather across Canada. This excess does not include variable wind and solar generation, which within a province can’t be guaranteed to be available when needed most.

This attitude must change. Transmission is cheaper than generation, and coordinated macrogrids can further improve reliability and cut costs. By constructing a substantial grid with low profile and aesthetically designed overhead transmission lines, the excess reserve of thermal and hydroelectric generation above the peak electric load can be reduced in each province over time. Detailed assessments will ensure each province retains its required reliability of electric supply.

As the provinces retire aging thermal and coal-fired generators, they only need to replace them to a much lower level, by just enough to meet their future electric loads and Canada's net-zero grid by 2050 goals. Some of the money not spent in replacing retired generation can be profitably invested in the transmission grid across the four western provinces.

But what about Alberta, which does not want to trade electric energy with the other western provinces? It can carry on as usual within the Alberta Electric System Operator’s (AESO) market and will save money by keeping the installed reserve of thermal and hydroelectric generation to a minimum. When Alberta experiences a peak electric load day and some generators are out of service due to unplanned maintenance, it can obtain the needed power from the interprovincial electric grid. None of the other three western provinces will peak at the same time, because of different weather and time zones, so they will have spare capacity to help Alberta over its peak. The peak load in a province only lasts for a few hours, so Alberta will get by with a little help from its friends if needed.

The grid will have no energy flowing on it for this purpose except to assist a province from time to time when it’s unable to meet its peak load. The grid may only carry load five per cent of the time in a year for this purpose. Under such circumstances, the empty grid can then be used for other profitable markets in electric energy. This includes more effective use of variable wind and solar energy, by enabling a province to better balance such intermittent power as well as allowing increased installation of it in every province. This is a challenge for AESO which the grid would substantially ease.

Natural Resources Canada promoted the “Regional Electricity Co-Operative and Strategic Infrastructure” initiative for completion this year and contracted through AESO, alongside an Atlantic grid study to explore regional improvements. This is a first step, but more is needed to achieve the full benefit of a western grid.

In 1970 a study was undertaken to electrically interconnect Britain with France, which was justified based on the ability to reduce reserve generation in both countries. Initially Britain rejected it, but France was partially supportive. In time, a substantial interconnection was built, and being a profitable venture, they are contemplating increasing the grid connections between them.

For the sake of the western consumers of electricity and to keep electricity rates from rising too quickly, as well as allowing productive expansion of wind and solar energy in places like British Columbia's clean energy shift efforts, an electric grid is essential across western Canada.

Dennis Woodford is president of Electranix Corporation in Winnipeg, which studies electric transmission problems, particularly involving renewable energy generators requiring firm connection to the grid.
