Energy Electricity generator seeks nuclear allies

UK Hydrogen Storage Caverns enable long-duration, low-carbon electricity balancing, storing surplus wind and solar power as green hydrogen in salt formations to enhance grid reliability, energy security, and net zero resilience by 2035 and 2050.

Key Points

They are salt caverns storing green hydrogen to balance wind and solar, stabilizing a low-carbon UK grid.

✅ Stores surplus wind and solar as green hydrogen in salt caverns

✅ Enables long-duration, low-carbon grid balancing and security

✅ Complements wind and solar; reduces dependence on flexible CCS

The U.K. government must kick-start the construction of large-scale hydrogen storage facilities if it is to meet its pledge that all electricity will come from low-carbon electricity sources by 2035 and reach legally binding net zero targets by 2050, according to a report by the Royal Society.

The report, "Large-scale electricity storage," published Sep. 8, examines a wide variety of ways to store surplus wind and solar generated electricity—including green hydrogen, advanced compressed air energy storage (ACAES), ammonia, and heat—which will be needed when Great Britain's electricity generation is dominated by volatile wind and solar power.

It concludes that large scale electricity storage is essential to mitigate variations in wind and sunshine, particularly long-term variations in the wind, and to keep the nation's lights on. Storing most of the surplus as hydrogen, in salt caverns, would be the cheapest way of doing this.

The report, based on 37 years of weather data, finds that in 2050 up to 100 Terawatt-hours (TWh) of storage will be needed, which would have to be capable of meeting around a quarter of the U.K.'s current annual electricity demand. This would be equivalent to more than 5,000 Dinorwig pumped hydroelectric dams. Storage on this scale, which would require up to 90 clusters of 10 caverns, is not possible with batteries or pumped hydro.

Storage requirements on this scale are not currently foreseen by the government, and the U.K.'s energy transition faces supply delays. Work on constructing these caverns should begin immediately if the government is to have any chance of meeting its net zero targets, the report states.

Sir Chris Llewellyn Smith FRS, lead author of the report, said, "The need for long-term storage has been seriously underestimated. Demand for electricity is expected to double by 2050 with the electrification of heat, transport, and industrial processing, as well as increases in the use of air conditioning, economic growth, and changes in population.

"It will mainly be met by wind and solar generation. They are the cheapest forms of low-carbon electricity generation, but are volatile—wind varies on a decadal timescale, so will have to be complemented by large scale supply from energy storage or other sources."

The only other large-scale low-carbon sources are nuclear power, gas with carbon capture and storage (CCS), and bioenergy without or with CCS (BECCS). While nuclear and gas with CCS are expected to play a role, they are expensive, especially if operated flexibly.

Sir Peter Bruce, vice president of the Royal Society, said, "Ensuring our future electricity supply remains reliable and resilient will be crucial for our future prosperity and well-being. An electricity system with significant wind and solar generation is likely to offer the lowest cost electricity but it is essential to have large-scale energy stores that can be accessed quickly to ensure Great Britain's energy security and sovereignty."

Combining hydrogen with ACAES, or other forms of storage that are more efficient than hydrogen, could lower the average cost of electricity overall, and would lower the required level of wind power and solar supply.

There are currently three hydrogen storage caverns in the U.K., which have been in use since 1972, and the British Geological Survey has identified the geology for ample storage capacity in Cheshire, Wessex and East Yorkshire. Appropriate, novel business models and market structures will be needed to encourage construction of the large number of additional caverns that will be needed, the report says.

Sir Chris observes that, although nuclear, hydro and other sources are likely to play a role, Britain could in principle be powered solely by wind power and solar, supported by hydrogen, and some small-scale storage provided, for example, by batteries, that can respond rapidly and to stabilize the grid. While the cost of electricity would be higher than in the last decade, we anticipate it would be much lower than in 2022, he adds.

BC Hydro COVID-19 Site C updates detail monitoring, self-isolation at the work camp, Northern Health coordination, social distancing, reduced staffing, progress on diversion tunnels, Highway 29 realignment, and public reports to Peace River Regional District.

Key Points

Regular reports on COVID-19 monitoring, isolation protocols, staffing, and Site C work with Northern Health.

✅ Daily updates to Peace River Regional District

✅ Isolation rooms reserved in camp dorms

✅ Construction continues with social distancing

BC Hydro says it will begin giving regular updates to the public and the Peace River Regional District about its monitoring of the coronavirus COVID-19 at Site C, reflecting broader industry alerts such as a U.S. grid warning on pandemic risks.

BC Hydro met with the Peace River Regional District Sunday via phone call to discuss the forthcoming measures.

"We did a make a commitment to provide regular updates to Peace River Regional District member communities on an ongoing basis," said spokesman Dave Conway.

"(It's) certainly one of the things that we heard that they want and we heard that strongly and repeatedly."

Conway said updates could be posted as early as Monday on BC Hydro's website for the project.

As of March 23, there were sixteen people in self-isolation at the work camp just outside Fort St. John. Conway did not know how many of the workers have been tested for the virus, but said there are no confirmed cases on site. Provincial guidelines are being followed, he said.

"If they show any of the following symptoms, so sneezing, sore throat, muscle aches, headaches, coughs, or difficulty breathing, they're isolated for 14 days," Conway said.

"We're being very cautious of our application of the guidelines. We're asking anybody to self isolate if they have any slight symptoms."

BC Hydro has set aside one 30-room dorm at the camp for workers who need to isolate themselves, similar to measures in other jurisdictions where the power industry may house staff on-site to maintain operations, and has another four dorms with another 120 rooms that can be used as necessary. Conway could not immediately say whether additional rooms at hotels or at its apartment block have also been reserved.

There have been  700 workers home since a scale-back in construction was announced on March 18, and more workers are expected to be sent home this week. There were 940 people in camp on March 23, Conway said.

"To put that into perspective, the number of people staying in camp at this time of year, based on previous years, usually averages around 1,700," Conway said.

Brad Sperling, board chair for the Peace River Regional District, said BC Hydro has committed to formulating a strategy over the next few days to keep local government and public informed.

Electoral director Karen Goodings said she was pleased by that, and that it's important to everyone that BC Hydro works with Northern Health and adheres to provincial guidelines.

"The senior governments are critical to what measures will be undertaken not only on the project, including the camp, but also on the rules around transportation of workers and on addressing workplace conduct investigations at other utilities," Goodings wrote in an email.

On Sunday, the Site C leisure bus was seen at Totem Mall with two passengers on board.

Conway said the ongoing use of the shuttle is being monitored and evaluated, and is operating under social distancing and extra cleaning guidelines aligned with public transportation changes that have come under BC Transit.

The bus makes 10 trips per day from the camp, with an average of two passengers per trip, Conway said.

"We still have, of course, people in camp, and it's an opportunity for guests to get out and go for a walk and re-provision themselves for essentials for personal needs," Conway said.

Construction of the river diversion tunnels continues to meet a fall deadline, while work also carries on to realign Highway 29, build the transmission line, and clear the valley and future reservoir. Other site security and environmental monitoring work also continues, as utilities confront a dangerous dam-climbing trend driven by social media.

BC Hydro has said measures have been put into place, amid concerns similar to those voiced by nuclear plant workers about precautions at industrial sites, to minimize the potential spread of the COVID-19 on site, such as closing the camp gym and theatre, eliminating self serve dining stations, as well as non-essential travel, tours, and meetings.

Some workers, however, have raised worries about the tight working conditions on site, noting field safety incidents that highlight risks in the sector.

The province announced Monday 48 new cases in B.C., including one more in the Northern Health region, bringing the region's total to five, while Saskatchewan's numbers show how the crisis has reshaped that province. Their precise whereabouts are not being reported by B.C. public health officials.

IESO Capacity Auctions will competitively procure resources for Ontario electricity needs, boosting reliability and resource adequacy through market-based bidding, enabling demand response, energy storage, and flexible supply to meet changing load and regional grid conditions.

Key Points

A competitive, technology-neutral auction buys capacity at lowest cost to keep Ontario's grid reliable and flexible.

✅ Market-based procurement reduces system costs.

✅ Enables demand response, storage, and hybrid resources.

✅ Increases flexibility and regional reliability in Ontario.

The Independent Electricity System Operator (IESO) is introducing changes to Ontario's electricity system that will help save Ontarians about $3.4 billion over a 10-year period. The changes include holding annual capacity auctions to acquire electricity resources at lowest cost that can be called upon when and where they are needed to meet Ontario electricity needs. 

Today's announcement marks the release of a high level design for future auctions, with changes for electricity consumers expected as the first is set to be held in late 2022.

"These auctions will specify how much electricity we need, and introduce a competitive process to determine who can meet that need. It's a competition among all eligible resources, and it's the Ontario consumer, including industrial electricity ratepayers, who benefits through lower costs and a more flexible system better able to respond to changing demand and supply conditions," says IESO President and CEO Peter Gregg.

In the past decade, electricity supply was typically acquired through very prescriptive means with defined targets for specific types of resources such as wind and solar, and secured through 20-year contracts.  While these long-term commitments helped Ontario transform its generation fleet over the last decade, electricity cost allocation also played a role, but longer term contracts provide limited flexibility in dealing with unexpected changes in the power system. 

"Imagine signing a 20-year contract for your cable TV service. In five years' time, electricity rates could be lower, new competitors may have entered the market, or entirely new and innovative platforms and services like Netflix may have emerged. You miss out on opportunities for improvement by being locked-in," says Gregg.

Provincial electricity demand has traditionally fluctuated over time due to factors like economic growth, conservation and the introduction of generating resources on local distribution systems, with occasional issues such as phantom demand affecting customers' costs as well. Technological changes are adding another layer of uncertainty to future demand as electric vehicles, energy storage and low-cost solar panels become more common.

"Our planners do their best to forecast electricity demand, but the truth is there's no such thing as certainty in electricity planning. That's why flexibility is so important. We don't want Ontarians to have to pay more on the typical Ontario electricity bill for electricity resources than are needed to ensure a reliable power system that can continue to meet Ontario's needs," says IESO Vice President and COO Leonard Kula.

New Mexico EV Benefits highlight cheaper fuel, lower maintenance, cleaner air, and smarter charging, cutting utility bills, reducing NOx and carbon emissions, and leveraging incentives and renewable energy to accelerate EV adoption statewide.

Key Points

New Mexico EV Benefits are the cost, grid, and emissions gains from EV adoption and optimized off-peak charging.

✅ Electricity near $1.11 per gallon equivalent cuts fueling costs

✅ Fewer moving parts mean less maintenance and lifecycle costs

✅ Off-peak charging reduces utility bills and grid emissions

What would happen if New Mexicans ditched gasoline and started to drive on cleaner, cheaper electricity? A new report from MJ Bradley & Associates, commissioned by NRDC and Southwest Energy Efficiency Project, answers that question, demonstrating that New Mexico could realize $30 billion in avoided expenditures on gasoline and maintenance, reduced utility bills, and environmental benefits by 2050. The state is currently considering legislation to jump-start that transition by providing consumers incentives to support electric vehicle (EV) purchases and the installation of charging stations, drawing on examples like Nevada's clean-vehicle push to accelerate deployment, a policy that would require a few million dollars in lost tax revenue. The report shows an investment of this kind could yield tens of billions of dollars in net benefits.

$20 Billion in Driver Savings

EVs save families money because driving on electricity in New Mexico is the cost-equivalent of driving on $1.11 per gallon gasoline. Furthermore, EVs have fewer moving parts and less required maintenance—no oil changes, no transmissions, no mufflers, no timing belts, etc. That means that tackling the nation’s largest source of carbon pollution, transportation, could save New Mexicans over $20 billion by 2050 because EVs are cheaper to charge and maintain than gas powered cars, and an EV boom benefits all customers through lower rates.

Those are savings New Mexico can bank on because the price of electricity is significantly cheaper than the price of gasoline and also inherently more stable. Electricity is made from a diverse supply of domestic and increasingly clean resources, and 2021 electricity lessons continue to inform grid planning today. Unlike the volatile world oil market, New Mexico’s electric sector is regulated by the state’s utility commission. Adjusted for inflation, the price of electricity has been steady around the dollar-a-gallon equivalent mark in New Mexico for the last 20 years, while gas prices jump up or down radically and unpredictably.

$4.8 Billion in Reduced Electric Bills

While some warn that electric cars will challenge state power grids, New Mexico can charge millions of EVs without the need to make significant investments in the electric grid. This is because EVs can be charged when the grid is underutilized and renewable energy is abundant, like when people are sleeping overnight when wind energy generation often peaks. And the billions of dollars in new utility revenue from EV charging in excess of associated costs will be automatically returned to utility customers per an accounting mechanism that is already in state law that requires downward adjustment of rates when sales increase. Accordingly, widespread EV adoption could reduce every utility customer’s electric bill.

Thankfully, New Mexico’s electric industry is already acting to ensure utility customers in the state realize those benefits sooner rather than later. The state’s rural electric cooperatives have proposed an ambitious plan to leverage funds available as a result of the Volkswagen diesel scandal to build a state-wide public fast charging network that mirrors progress as Arizona goes EV across the Southwest. Additionally, New Mexico’s investor-owned utilities will soon propose transportation electrification investments as required by legislation NRDC supported last year that Governor Lujan Grisham signed into law.

$4.8 Billion in Societal Benefits from Reduced Pollution

The report estimates that widespread EV adoption would dramatically reduce emissions of greenhouse gases from passenger vehicles in New Mexico, and also cut emissions of NOx, a local pollutant that threatens the health off all New Mexicans, especially children and people with respiratory conditions. The report finds growing the state’s EV market to meet New Mexico’s long-term environmental goals would yield $4.8 billion in societal benefits.

The Bottom Line: New Mexico Should Act Now to Accelerate its EV Market

Adding it all up, that’s more than $30 billion in potential benefits to New Mexico by 2050. Here’s the catch: as of June 2019, there were only 2,500 EVs registered in New Mexico, which means the state needs to accelerate the EV market, as the American EV boom ramps up nationally, to capture those billions of dollars in potential benefits. Thankfully, with second generation, longer range, affordable EVs now available, the market is well positioned to expand rapidly as the state moves to adopt Clean Car Standards that will ensure EVs are available for purchase in the state.

Getting it right

New Mexico has enormous amounts to gain from a small investment in incentives that support EV adoption now. For that investment to pay off, it needs to send a clear and unambiguous signal. Unfortunately, the same legislation that would establish tax credits to increase consumer access to electric vehicles in New Mexico was recently amended so it would not be helpful for 80 percent of consumers who lease, instead of buying EVs. And it would penalize EV drivers at the same time—with a $100 annual increase in registration fees, even as Texas adds a $200 EV fee under a similar rationale, to make up for lost gas tax revenue. That’s significantly more than what drivers of new gasoline vehicles pay annually in gas taxes in the state. Consumer Reports recently analyzed the growing trend to unfairly penalize electric cars via disproportionately high registration fees. In doing so, it estimated that the “maximum justifiable fee” to replace gas tax revenue in New Mexico would be $53. Anything higher will only slow or stop benefits New Mexico can attain from moving to cleaner cars.

To be clear, everyone should pay their fair share to maintain the transportation system, but EVs are not the problem when it comes to lost gas tax revenue. We need a comprehensive solution that addresses the real sources of transportation revenue loss while not undermining efforts to reduce dependence on gasoline. Thankfully, that can be done.

Manitoba-Minnesota Transmission Project faces NEB certificate review, with public hearings, Indigenous consultation, and cross-border approval weighing permit vs certificate timelines, potential land expropriation, and Hydro's 2020 in-service date for the 308-MW intertie.

Key Points

A cross-border hydro line linking Manitoba and Minnesota, now under NEB review through a permit or certificate process.

✅ NEB recommends certificate with public hearings and cabinet approval

✅ Stakeholders cite land, health, and economic impacts along route

✅ Hydro targets May-June 2020 in-service despite review

A recommendation from the National Energy Board could push back the construction start date of a $453-million hydroelectric transmission line from Manitoba to Minnesota.

In a letter to federal Natural Resources Minister Jim Carr, the regulatory agency recommends using a "certificate" approval process, which could take more time than the simpler "permit" process Manitoba Hydro favours.

The certificate process involves public hearings, reflecting First Nations intervention seen in other power-line debates, to weigh the merits of the project, which would then go to the federal cabinet for approval.

The NEB says this process would allow for more procedural flexibility and "address Aboriginal concerns that may arise in the circumstances of this process."

The Manitoba-Minnesota Transmission Project would provide the final link in a chain that brings hydroelectricity from generating stations in northern Manitoba, through the Bipole III transmission line and, like the New England Clean Power Link project, across the U.S. border as part of a 308-megawatt deal with the Green Bay-based Wisconsin Public Service.

When Hydro filed its application in December 2016, it had expected to have approval by the end of August 2017 and to begin construction on the line in mid-December, in order to have the line in operation by May or June 2020.  

Groups representing stakeholders along the proposed route of the transmission line had mixed reactions to the energy board's recommendation.

A lawyer representing a coalition of more than 120 landowners in the Rural Municipality of Taché and around La Broquerie, Man., welcomed the opportunity to have a more "fulsome" discussion about the project.

"I think it's a positive step. As people become more familiar with the project, the deficiencies with it become more obvious," said Kevin Toyne, who represents the Southeast Stakeholders Coalition.

Toyne said some coalition members are worried that Hydro will forcibly expropriate land in order to build the line, while others are worried about potential economic and health impacts of having the line so close to their homes. They have proposed moving the line farther east.

When the Clean Environment Commission — an arm's-length provincial government agency — held public hearings on the proposed route earlier this year, the coalition brought their concerns forward, echoing Site C opposition voiced by northerners, but Toyne says both the commission and Hydro ignored them.

Hydro still aiming for 2020 in-service date

The Manitoba Métis Federation also participated in those public hearings. MMF president David Chartrand worries about the impact a possible delay, as seen with the Site C work halt tied to treaty rights, could have on revenue from sales of hydroelectric power to the U.S.

"I know that a lot of money, billions have been invested on this line. And if the connection line is not done, then of course this will be sitting here, not gaining any revenue, which will affect every Métis in this province, given our Hydro bill's going to go up," Chartrand said.The NEB letter to Minister Carr requests that he "determine this matter in an expedited manner."

Manitoba Hydro spokesperson Bruce Owen said in an email that the Crown corporation will participate in whatever process, permit or certificate, the NEB takes.

"Manitoba Hydro does not have any information at this point in time that would change the estimated in-service date (May-June 2020) for the Manitoba-Minnesota Transmission Project," he said.

The federal government "is currently reviewing the NEB's recommendation to designate the project as subject to a certificate, which would result in public hearings," said Alexandre Deslongchamps, a spokesperson for Carr.

"Under the National Energy Board Act, an international power line requires either the approval by the NEB through a permit or approval by the Government of Canada by a certificate. Both must be issued by the NEB," he wrote in an email to CBC News.

By law, the certificate process is not to take longer than 15 months.

Alberta Electricity Price Surge reflects soaring wholesale rates, natural gas spikes, carbon tax pressures, and grid decarbonization challenges amid cold-weather demand, constrained supply, and Europe-style energy crisis impacts across the province.

Key Points

An exceptional jump in Alberta's power costs driven by gas price spikes, high demand, policy costs, and tight supply.

✅ Wholesale prices averaged $123/MWh in December

✅ Gas costs surged; supply constraints and outages

✅ Carbon tax and decarbonization policies raised costs

Albertans just endured the highest electricity prices in 21 years. Wholesale prices averaged $123 per megawatt-hour in December, more than triple the level from the previous year and highest for December since 2000.

The situation in Alberta mirrors the energy crisis striking Europe where electricity prices are also surging, largely due to a shocking five-fold increase in natural gas prices in 2021 compared to the prior year.

The situation should give pause to Albertans when they consider aggressive plans to “decarbonize” the electric grid, including proposals for a fully renewable grid by 2030 from some policymakers.

The explanation for skyrocketing energy prices is simple: increased demand (because of Calgary's frigid February demand and a slowly-reviving post-pandemic economy) coupled with constrained supply.

In the nitty gritty details, there are always particular transitory causes, such as disputes with Russian gas companies (in the case of Europe) or plant outages (in the case of Alberta).

But beyond these fleeting factors, there are more permanent systemic constraints on natural gas (and even more so, coal-fired) power plants.

I refer of course to the climate change policies of the Trudeau government at the federal level and some of the more aggressive provincial governments, which have notable implications for electricity grids across Canada.

The most obvious example is the carbon tax, the repeal of which Premier Jason Kenney made a staple of his government.

Putting aside the constitutional issues (on which the Supreme Court ruled in March of last year that the federal government could impose a carbon tax on Alberta), the obvious economic impact will be to make carbon-sourced electricity more expensive.

This isn’t a bug or undesired side-effect, it’s the explicit purpose of a carbon tax.

Right now, the federal carbon tax is $40 per tonne, is scheduled to increase to $50 in April, and will ultimately max out at a whopping $170 per tonne in 2030.

Again, the conscious rationale of the tax, aligned with goals for cleaning up Canada's electricity, is to make coal, oil and natural gas more expensive to induce consumers and businesses to use alternative energy sources.

As Albertans experience sticker shock this winter, they should ask themselves — do we want the government intentionally making electricity and heating oil more expensive?

Of course, the proponent of a carbon tax (and other measures designed to shift Canadians away from carbon-based fuels) would respond that it’s a necessary measure in the fight against climate change, and that Canada will need more electricity to hit net-zero according to the IEA.

Yet the reality is that Canada is a bit player on the world stage when it comes to carbon dioxide, responsible for only 1.5% of global emissions (as of 2018).

As reported at this “climate tracker” website, if we look at the actual policies put in place by governments around the world, they’re collectively on track for the Earth to warm 2.7 degrees Celsius by 2100, far above the official target codified in the Paris Agreement.

Canadians can’t do much to alter the global temperature, but federal and provincial governments can make energy more expensive if policymakers so choose, and large-scale electrification could be costly—the Canadian Gas Association warns of $1.4 trillion— if pursued rapidly.

As renewable technologies become more reliable and affordable, business and consumers will naturally adopt them; it didn’t take a “manure tax” to force people to use cars rather than horses.

As official policy continues to make electricity more expensive, Albertans should ask if this approach is really worth it, or whether options like bridging the Alberta-B.C. electricity gap could better balance costs.

Robert P. Murphy is a senior fellow at the Fraser Institute.
