Utilities prepare for major projects: Landholders told of infrastructure plans

Canadian electricity transmission enables grid resilience, long-distance power trade, and decarbonization by integrating renewables, hydroelectric storage, and HVDC links, providing backup during extreme weather and lowering costs to reach net-zero, clean energy targets.

Key Points

An interprovincial high-voltage grid that shares clean power to deliver reliable, low-cost decarbonization.

✅ Enables resilience by sharing power across weather zones

✅ Integrates renewables with hydro storage via HVDC links

✅ Lowers decarbonization costs through interprovincial trade

As the recent disaster in Texas showed, climate change requires electricity utilities to prepare for extreme events. This “global weirding” is leaving Canadian electricity grids increasingly exposed to harsh weather that leads to more intense storms, higher wind speeds, heatwaves and droughts that can threaten the performance of electricity systems.

The electricity sector must adapt to this changing climate while also playing a central role in mitigating climate change. Greenhouse gas emissions can be reduced a number of ways, but the electricity sector is expected to play a central role in decarbonization, including powering a net-zero grid by 2050 across Canada. Zero-emissions electricity can be used to electrify transportation, heating and industry and help achieve emissions reduction in these sectors.

Enhancing long-distance transmission is viewed as a cost-effective way to enable a clean and reliable power grid, and to lower the cost of meeting our climate targets. Now is the time to strengthen transmission links in Canada, with concepts like a western Canadian electricity grid gaining traction.

Insurance for climate extremes
An early lesson from the Texas power outages is that extreme conditions can lead to failures across all forms of power supply. The state lost the capacity to generate electricity from natural gas, coal, nuclear and wind simultaneously. But it also lacked cross-border transmission to other electricity systems that could have bolstered supply.

Long-distance transmission offers the opportunity to escape the correlative clutch of extreme weather, by accessing energy and spare capacity in areas not beset by the same weather patterns. For example, while Texas was in its deep freeze, relatively balmy conditions in California meant there was a surplus of electricity generation capability in that region — but no means to get it to Texas. Building new transmission lines and connections across broader regions, including projects like a hydropower line to New York that expand access, can act as an insurance policy, providing a back-up for regions hit by the crippling effects of climate change.

Transmission is also vulnerable to climate disruptions, such as crippling ice storms that leave wires temporarily inoperable. This may mean using stronger poles when building transmission, or burying major high-voltage transmission links, or deploying superconducting cables to reduce losses.

In any event, more transmission links between regions can improve resilience by co-ordinating supply across larger regions. Well-connected grids that are larger than the areas disrupted by weather systems can be more resilient to climate extremes.

Lowering the cost of clean power
Adding more transmission can also play a role in mitigating climate change. Numerous studies have found that building a larger transmission grid allows for greater shares of renewables onto the grid, ultimately lowering the overall cost of electricity.

In a recent study, two of us looked at the role transmission could play in lowering greenhouse gas emissions in Canada’s electricity sector. We found the cost of reducing greenhouse gas emissions is lower when new or enhanced transmission links can be built between provinces.

Much of the value of transmission in these scenarios comes from linking high-quality wind and solar resources with flexible zero-emission generation that can produce electricity on demand. In Canada, our system is dominated by hydroelectricity, but most of this hydro capacity is located in five provinces: British Columbia, Manitoba, Ontario, Québec and Newfoundland and Labrador.

In the west, Alberta and Saskatchewan are great locations for building low-cost wind and solar farms. Enhanced interprovincial transmission would allow Alberta and Saskatchewan to build more variable wind and solar, with the assurance that they could receive backup power from B.C. and Manitoba when the wind isn’t blowing and the sun isn’t shining.

When wind and solar are plentiful, the flow of low cost energy can reverse to allow B.C. and Manitoba the opportunity to better manage their hydro reservoir levels. Provinces can only benefit from trading with each other if we have the infrastructure to make that trade possible.

A recent working paper examined the role that new transmission links could play in decarbonizing the B.C. and Alberta electricity systems. We again found that enabling greater electricity trade between B.C. and Alberta can reduce the cost of deep cuts to greenhouse gas emissions by billions of dollars a year. Although we focused on the value of the Site C project, in the context of B.C.'s clean energy shift, the analysis showed that new transmission would offer benefits of much greater value than a single hydroelectric project.

Getting transmission built
With the benefits that enhanced electricity transmission links can provide, one might think new projects would be a slam dunk. But there are barriers to getting projects built.

First, electricity grids in Canada are managed at the provincial level, most often by Crown corporations. Decisions by the Crowns are influenced not simply by economics, but also by political considerations. If a transmission project enables greater imports of electricity to Saskatchewan from Manitoba, it raises a flag about lost economic development opportunity within Saskatchewan. Successful transmission agreements need to ensure a two-way flow of benefits.

Second, transmission can be expensive. On this front, the Canadian government could open up the purse strings to fund new transmission links between provinces. It has already shown a willingness to do so.

Lastly, transmission lines are long linear projects, not unlike pipelines. Siting transmission lines can be contentious, even when they are delivering zero-emissions electricity. Using infrastructure corridors, such as existing railway right of ways or the proposed Canadian Northern Corridor, could help better facilitate co-operation between regions and reduce the risks of siting transmission lines.

If Canada can address these barriers to transmission, we should find ourselves in an advantageous position, where we are more resilient to climate extremes and have achieved a lower-cost, zero-emissions electricity grid.

Space solar power promises wireless energy from orbital solar satellites via microwave or laser power beaming, using photovoltaics and rectennas. NRL and AFRL advances hint at 24-7 renewable power delivery to Earth and airborne drones.

Key Points

Space solar power beams orbital solar energy to Earth via microwaves or lasers, enabling continuous wireless electricity.

✅ Harvests sunlight in orbit and transmits via microwaves or lasers

✅ Provides 24-7 renewable power, independent of weather or night

✅ Enables wireless power for remote sites, grids, and drones

Earlier this year, a small group of spectators gathered in David Taylor Model Basin, the Navy’s cavernous indoor wave pool in Maryland, to watch something they couldn’t see. At each end of the facility there was a 13-foot pole with a small cube perched on top. A powerful infrared laser beam shot out of one of the cubes, striking an array of photovoltaic cells inside the opposite cube. To the naked eye, however, it looked like a whole lot of nothing. The only evidence that anything was happening came from a small coffee maker nearby, which was churning out “laser lattes” using only the power generated by the system as ambitions for cheap abundant electricity gain momentum worldwide.

The laser setup managed to transmit 400 watts of power—enough for several small household appliances—through hundreds of meters of air without moving any mass. The Naval Research Lab, which ran the project, hopes to use the system to send power to drones during flight. But NRL electronics engineer Paul Jaffe has his sights set on an even more ambitious problem: beaming solar power to Earth from space. For decades the idea had been reserved for The Future, but a series of technological breakthroughs and a massive new government research program suggest that faraway day may have finally arrived as interest in space-based solar broadens across industry and government.

Since the idea for space solar power first cropped up in Isaac Asimov’s science fiction in the early 1940s, scientists and engineers have floated dozens of proposals to bring the concept to life, including inflatable solar arrays and robotic self-assembly. But the basic idea is always the same: A giant satellite in orbit harvests energy from the sun and converts it to microwaves or lasers for transmission to Earth, where it is converted into electricity. The sun never sets in space, so a space solar power system could supply renewable power to anywhere on the planet, day or night, as recent tests show we can generate electricity from the night sky as well, rain or shine.

Like fusion energy, space-based solar power seemed doomed to become a technology that was always 30 years away. Technical problems kept cropping up, cost estimates remained stratospheric, and as solar cells became cheaper and more efficient, and storage improved with cheap batteries, the case for space-based solar seemed to be shrinking.

That didn’t stop government research agencies from trying. In 1975, after partnering with the Department of Energy on a series of space solar power feasibility studies, NASA beamed 30 kilowatts of power over a mile using a giant microwave dish. Beamed energy is a crucial aspect of space solar power, but this test remains the most powerful demonstration of the technology to date. “The fact that it’s been almost 45 years since NASA’s demonstration, and it remains the high-water mark, speaks for itself,” Jaffe says. “Space solar wasn’t a national imperative, and so a lot of this technology didn’t meaningfully progress.”

John Mankins, a former physicist at NASA and director of Solar Space Technologies, witnessed how government bureaucracy killed space solar power development firsthand. In the late 1990s, Mankins authored a report for NASA that concluded it was again time to take space solar power seriously and led a project to do design studies on a satellite system. Despite some promising results, the agency ended up abandoning it.

In 2005, Mankins left NASA to work as a consultant, but he couldn’t shake the idea of space solar power. He did some modest space solar power experiments himself and even got a grant from NASA’s Innovative Advanced Concepts program in 2011. The result was SPS-ALPHA, which Mankins called “the first practical solar power satellite.” The idea, says Mankins, was “to build a large solar-powered satellite out of thousands of small pieces.” His modular design brought the cost of hardware down significantly, at least in principle.

Jaffe, who was just starting to work on hardware for space solar power at the Naval Research Lab, got excited about Mankins’ concept. At the time he was developing a “sandwich module” consisting of a small solar panel on one side and a microwave transmitter on the other. His electronic sandwich demonstrated all the elements of an actual space solar power system and, perhaps most important, it was modular. It could work beautifully with something like Mankins' concept, he figured. All they were missing was the financial support to bring the idea from the laboratory into space.

Jaffe invited Mankins to join a small team of researchers entering a Defense Department competition, in which they were planning to pitch a space solar power concept based on SPS-ALPHA. In 2016, the team presented the idea to top Defense officials and ended up winning four out of the seven award categories. Both Jaffe and Mankins described it as a crucial moment for reviving the US government’s interest in space solar power.

They might be right. In October, the Air Force Research Lab announced a $100 million program to develop hardware for a solar power satellite. It’s an important first step toward the first demonstration of space solar power in orbit, and Mankins says it could help solve what he sees as space solar power’s biggest problem: public perception. The technology has always seemed like a pie-in-the-sky idea, and the cost of setting up a solar array on Earth is plummeting, as proposals like a tenfold U.S. solar expansion signal rapid growth; but space solar power has unique benefits, chief among them the availability of solar energy around the clock regardless of the weather or time of day.

It can also provide renewable energy to remote locations, such as forward operating bases for the military, which has deployed its first floating solar array to bolster resilience. And at a time when wildfires have forced the utility PG&E to kill power for thousands of California residents on multiple occasions, having a way to provide renewable energy through the clouds and smoke doesn’t seem like such a bad idea. (Ironically enough, PG&E entered a first-of-its-kind agreement to buy space solar power from a company called Solaren back in 2009; the system was supposed to start operating in 2016 but never came to fruition.)

“If space solar power does work, it is hard to overstate what the geopolitical implications would be,” Jaffe says. “With GPS, we sort of take it for granted that no matter where we are on this planet, we can get precise navigation information. If the same thing could be done for energy, especially as peer-to-peer energy sharing matures, it would be revolutionary.”

Indeed, there seems to be an emerging race to become the first to harness this technology. Earlier this year China announced its intention to become the first country to build a solar power station in space, and for more than a decade Japan has considered the development of a space solar power station to be a national priority. Now that the US military has joined in with a $100 million hardware development program, it may only be a matter of time before there’s a solar farm in the solar system.

France Diesel Prices at Pre-Ukraine Levels reflect energy market stabilization as supply chains adapt and subsidies help; easing fuel costs, inflation, and logistics burdens for households, transport firms, and the wider economy.

Key Points

They mark normalization as oil supply stabilizes, easing fuel costs and logistics expenses for consumers and firms.

✅ Lower transport and logistics operating costs

✅ Softer inflation and improved household budgets

✅ Market stabilization amid adjusted oil supply chains

In a significant development for French consumers and businesses alike, diesel prices in France have recently fallen back to levels last seen before the Ukrainian conflict began, mirroring European gas prices returning to pre-war levels across the region. This drop comes as a relief to many who have been grappling with volatile energy costs and their impact on the cost of living and business operations. The return to lower diesel prices is a noteworthy shift in the energy landscape, with implications for the French economy, transportation sector, and broader European market.

Context of Rising Diesel Prices

The onset of the Ukrainian conflict in early 2022 triggered a dramatic increase in global energy prices, including diesel. The conflict's disruption of supply chains, coupled with sanctions on Russian oil and gas exports, contributed to a steep rise in fuel prices across Europe, prompting the EU to weigh emergency electricity price measures to shield consumers. For France, this meant that diesel prices soared to unprecedented levels, putting significant pressure on consumers and businesses that rely heavily on diesel for transportation and logistics.

The impact was felt across various sectors. Transportation companies faced higher operational costs, which were often passed down to consumers in the form of increased prices for goods and services. Additionally, higher fuel costs contributed to broader inflationary pressures, with EU inflation hitting lower-income households hardest, affecting household budgets and overall economic stability.

Recent Price Trends and Market Adjustments

The recent decline in diesel prices in France is a welcome reversal from the peak levels experienced during the height of the conflict. Several factors have contributed to this price reduction. Firstly, there has been a stabilization of global oil markets as geopolitical tensions have somewhat eased and supply chains have adjusted to new realities. The gradual return of Russian oil to global markets, albeit under complex sanctions and trading arrangements, has also played a role in moderating prices.

Moreover, France's strategic reserves and diversified energy sources have helped cushion the impact of global price fluctuations. The French government has also implemented measures to stabilize energy prices, including subsidies and tax adjustments, and a new electricity pricing scheme to satisfy EU concerns, which have helped alleviate some of the financial pressure on consumers.

Implications for the French Economy

The return to pre-conflict diesel price levels brings several positive implications for the French economy. For consumers, the decrease in fuel prices means lower transportation costs, which can ease inflationary pressures and improve disposable income, and, alongside the EDF electricity price deal, reduce overall utility burdens for households. This is particularly beneficial for households with long commutes or those relying on diesel-powered vehicles.

For businesses, especially those in the transportation and logistics sectors, the drop in diesel prices translates into reduced operational costs. This can help lower the cost of goods and services, potentially leading to lower prices for consumers and improved profitability for businesses. In a broader sense, stabilized fuel prices can contribute to overall economic stability and growth, as lower energy costs can support consumer spending and business investment.

Environmental and Policy Considerations

While the decrease in diesel prices is advantageous in the short term, it also raises questions about long-term energy policy and environmental impact, with the recent crisis framed as a wake-up call for Europe to accelerate the shift away from fossil fuels. Diesel, as a fossil fuel, continues to pose environmental challenges, including greenhouse gas emissions and air pollution. The drop in prices might inadvertently discourage investments in cleaner energy alternatives, such as electric and hybrid vehicles, which are crucial for achieving long-term sustainability goals.

In response, there is a growing call for continued investment in renewable energy and energy efficiency measures. France has been actively pursuing policies to reduce its reliance on fossil fuels and increase the adoption of cleaner technologies, amid ongoing EU electricity reform debates with Germany. The government’s support for green energy initiatives and incentives for low-emission vehicles will be essential in balancing short-term benefits with long-term environmental objectives.

Conclusion

The recent return of French diesel prices to pre-Ukrainian conflict levels marks a significant shift in the energy market, offering relief to both consumers and businesses. While this decline brings immediate financial benefits and supports economic stability, it also underscores the ongoing need for a strategic approach to energy policy and environmental sustainability. As France navigates the evolving energy landscape, the focus will need to remain on fostering a transition towards cleaner energy sources while managing the economic and environmental impacts of fuel price fluctuations.

Rooftop Solar Battery Backup helps Californians keep lights on during PG&E blackouts, combining home energy storage with grid-tied systems for wildfire prevention, outage resilience, and backup power when solar panels cannot supply nighttime demand.

Key Points

A home battery paired with rooftop solar, providing backup power and blackout resilience when the grid is down.

✅ Works when grid is down; panels alone stop for safety.

✅ Requires home battery storage; market adoption is growing.

✅ Supports wildfire mitigation and PG&E outage preparedness.

Californians have embraced rooftop solar panels more than anyone in the U.S., but amid California's solar boom many are learning the hard way the systems won’t keep the lights on during blackouts.

That’s because most panels are designed to supply power to the grid -- not directly to houses, though emerging peer-to-peer energy models may change how neighbors share power in coming years. During the heat of the day, solar systems can crank out more juice than a home can handle, a challenge also seen in excess solar risks in Australia today. Conversely, they don’t produce power at all at night. So systems are tied into the grid, and the vast majority aren’t working this week as PG&E Corp. cuts power to much of Northern California to prevent wildfires, even as wildfire smoke can dampen solar output during such events.

The only way for most solar panels to work during a blackout is pairing them with solar batteries that store excess energy. That market is just starting to take off. Sunrun Inc., the largest U.S. rooftop solar company, said some of its customers are making it through the blackouts with batteries, but it’s a tiny group -- countable in the hundreds.

“It’s the perfect combination for getting through these shutdowns,” Sunrun Chairman Ed Fenster said in an interview. He expects battery sales to boom in the wake of the outages, as the state has at times reached a near-100% renewables mark that heightens the need for storage.

And no, trying to run appliances off the power in a Tesla Inc. electric car won’t work, at least without special equipment, and widespread U.S. power-outage risks are a reminder to plan for home backup.

Ontario CDM Programs expand energy efficiency, demand response, and DER incentives via IESO's Save on Energy, cutting peak demand, lowering bills, and supporting electrification, retrofits, and LED lighting to meet Ontario's growing electricity needs.

Key Points

Ontario CDM Programs are IESO incentives that cut peak demand and energy use via demand response, retrofits and DERs.

✅ Delivered by IESO's Save on Energy to reduce peak demand

✅ Incentives for demand response, retrofits, LEDs, and DER solutions

✅ Help homes, businesses, and greenhouses lower bills and emissions

Ontario will be making available four new and expanded energy-efficiency programs, also known as Conservation and Demand Management (CDM) programs, to ensure a reliable, affordable, and clean electricity system, including ultra-low overnight pricing options to power the province, drive electrification and support strong economic growth. As there will be a need for additional electricity capacity in Ontario beginning in 2025, and continuing through the decade, CDM programs are among the fastest and most cost-effective ways of meeting electricity system needs.

Conservation and Demand Management

The Ontario government launched the 2021-2024 CDM Framework on January 1, 2021. The framework focuses on cost-effectively meeting the needs of Ontario’s electricity system, including by focusing on the achievement of provincial peak demand reductions and initiatives such as extended off-peak electricity rates, as well as on targeted approaches to address regional and/or local electricity system needs.

CDM programs are delivered by the Independent Electricity System Operator (IESO), which implemented staff lockdown measures during COVID-19, through the Save on Energy brand. These programs address electricity system needs and help consumers reduce their electricity consumption to lower their bills. CDM programs and incentives are available for homeowners, small businesses, large businesses, and contractors, and First Nations communities.

New and Expanded Programs

The four new and expanded CDM programs will include:

A new Residential Demand Response Program for homes with existing central air conditioning and smart thermostats to help deliver peak demand reductions. Households who meet the criteria could voluntarily enroll in this program and, alongside protections like disconnection moratoriums for residential customers, be paid an incentive in return for the IESO being able to reduce their cooling load on a select number of summer afternoons to reduce peak demand. There are an estimated 600,000 smart thermostats installed in Ontario.
Targeted support for greenhouses in Southwest Ontario, including incentives to install LED lighting, non-lighting measures or behind-the-meter distributed energy resources (DER), such as combined solar generation and battery storage.
Enhancements to the Save On Energy Retrofit Program for business, municipalities, institutional and industrial consumers to include custom energy-efficiency projects. Examples of potential projects could include chiller and other HVAC upgrades for a local arena, building automation and air handling systems for a hospital, or building envelope upgrades for a local business.
Enhancements to the Local Initiatives Program to reduce barriers to participation and to add flexibility for incentives for DER solutions.
It is the government’s intention that the new and expanded CDM programs will be available to eligible electricity customers beginning in Spring 2023.

The IESO estimates that the new program offers will deliver total provincial peak electricity demand savings of 285 megawatts (MW) and annual energy savings of 1.1 terawatt hours (TWh) by 2025, reflecting pandemic-era electricity usage shifts across Ontario. Savings will persist beyond 2025 with a total reduction in system costs by approximately $650 million over the lifetime of the measures, and will support economic recovery, as seen with electricity relief during COVID-19 measures, decarbonization and energy cost management for homes and businesses.

These enhancements will have a particular impact in Southwest Ontario, with regional peak demand savings of 225 MW, helping to alleviate electricity system constraints in the region and foster economic development, supported by stable electricity pricing for industrial and commercial companies in Ontario.

The overall savings from this CDM programming will result in an estimated three million tonnes of greenhouse gas emissions reductions over the lifetime of the energy-efficiency measures to help achieve Ontario’s climate targets and protect the environment for the future.

The IESO will be updating the CDM Framework Program Plan, which provides a detailed breakdown of program budgets and energy savings and peak demand targets expected to be achieved.

Energy Justice Program drives a renewables-based transition, challenging utility monopolies with legal action, promoting rooftop solar, distributed energy, public power, and climate justice to decarbonize the grid and protect communities and wildlife nationwide.

Key Points

A climate justice initiative advancing renewables, legal action, and public power to challenge utility monopolies.

✅ Challenges utility barriers to rooftop solar and distributed energy

✅ Advances state and federal policies for equitable, public power

✅ Uses litigation to curb fossil fuel dependence and protect communities

The Center for Biological Diversity on Monday rolled out a new program to push back against the nation's community- and wildlife-harming energy system that the climate advocacy group says is based on fossil fuels and a "centralized monopoly on power."

The goal of the new effort, the Energy Justice Program, is to help forge a path towards a just and renewables-based energy future informed by equitable regulation principles.

"Our broken energy system threatens our climate and our future," said Jean Su, the Energy Justice Program's new director, in a statement. "Utilities were given monopolies to ensure public access to electricity, but these dinosaur corporations are now hurting the public interest by blocking the clean energy transition, including via coal and nuclear subsidy schemes that profit off the fossil fuel era."

"In this era of climate catastrophe," she continued, "we have to stop these outdated monopolies and usher in a new electricity future that works for people and the planet."

To meet those goals, the new program will pursue a number of avenues, including using legal action to fight utilities' obstruction of clean energy efforts, helping communities advance local solar programs through energy freedom strategies in the South, and crafting energy policies on the state, federal, and international levels in step with commitments from major energy buyers to achieve a 90% carbon-free goal by 2030.

Some of that work is already underway. In June the Center filed a brief with a federal court in a bid to block Arizona power utility Salt River Project from slapping a 60-percent electricity rate hike on rooftop solar customers—amid federal efforts to reshape electricity pricing that critics say are being rushed—a move the group described (pdf) as an obstacle to achieving "the energy transition demanded by climate science."

The Center is among the groups in Energy Justice NC. The diverse coalition seeks to end the energy stranglehold in North Carolina held by Duke Energy, which continues to invest in fossil fuel projects even as it touts clean energy and grid investments in the region.

The time for a new energy system, says the Energy Justice Program, is now, as climate change impacts increasingly strain the grid.

"Amid this climate and extinction emergency," said Su, "the U.S. can't afford to stick with the same centralized, profit-driven electricity system that drove us here in the first place. We have to seize this once-in-a-generation opportunity to design a new system of accountable, equitable, truly public power."
