Nova Scotia can't order electric utility to lower power rates, minister says

Ukraine Power Grid Attacks intensify as missile and drone strikes hit substations and power plants, causing blackouts, humanitarian crises, strained hospitals, and emergency repairs, with winter energy shortages and civilian infrastructure damage worsening nationwide.

Key Points

Strikes on energy infrastructure causing blackouts, service disruption, and heightened humanitarian risk in winter.

✅ Missile and drone strikes cripple plants, substations, and lines

✅ Blackouts disrupt water, heating, hospitals, and critical services

✅ Emergency repairs, generators, and aid mitigate winter shortages

Ukraine's energy infrastructure remains a primary target in Russia's ongoing invasion, with a recent wave of missile strikes causing power outages in western regions and disrupting critical services across the country. These attacks have devastating humanitarian consequences, leaving millions of Ukrainians without heat, water, and electricity as winter approaches.

Systematic Targeting of Energy Infrastructure

Russia's strategy of deliberately targeting Ukraine's power grid marks a significant escalation, directly affecting the lives of civilians. Power plants, substations, and transmission lines have been hit with missiles and drones, with the latest strikes in late April causing blackouts in cities across Ukraine, including the capital, Kyiv, as the country fights to keep the lights on amid relentless bombardment.

Humanitarian Catastrophe Looms

The damage to Ukraine's electrical system hinders essential services like water supply, sewage treatment, and heating. Hospitals and other critical facilities struggle to operate without reliable power. With winter around the corner, the ongoing attacks threaten a humanitarian catastrophe even as authorities outline plans to keep the lights on this winter for vulnerable communities.

Ukrainian Resolve Remains Unbroken

Despite the devastation, Ukrainian engineers and workers race against time to repair damaged infrastructure and restore power as quickly as possible, while communities adopt new energy solutions to overcome blackouts to maintain essential services. The nation's energy workers have been hailed as heroes for their tireless efforts to keep the lights on amidst relentless attacks. Officials have urged civilians to reduce energy consumption whenever possible to alleviate strain on the fragile grid.

International Condemnation and Support

The systematic attacks on Ukraine's power grid have been widely condemned by the international community.  Western nations have accused Russia of war crimes, highlighting the deliberate targeting of civilian infrastructure. Aid organizations and countries are coordinating efforts to provide emergency power supplies, including generators and transformers, to help Ukraine mitigate the immediate crisis, even as the U.S. ended support for grid restoration in a recent policy shift.

Implications Beyond Ukraine

The humanitarian crisis unfolding in Ukraine due to power grid attacks carries implications far beyond its borders. The disruption of energy supplies could lead to further instability in neighbouring countries dependent on Ukraine's power exports, although officials say electricity reserves are sufficient to prevent scheduled outages if attacks subside. Additionally, a surge in Ukrainian refugees fleeing the deteriorating conditions could put a strain on resources within the European Union.

War Crimes Allegations

International human rights organizations are documenting evidence of Russia's deliberate attacks on Ukraine's civilian infrastructure. Human Rights Watch (HRW) has stated that Russia's targeting of power stations could violate the laws of war and amount to war crimes. This documentation will be crucial for holding Russia accountable for its actions in the future.

Uncertain Future for Ukraine's Power Supply

The long-term consequences of Russia's sustained attacks on Ukraine's power grid remain uncertain. While Ukrainian workers demonstrate incredible resilience, the sheer scale of repeated damage may eventually overwhelm their ability to keep pace with repairs, and, as winter looms over the battlefront, electricity is civilization for frontline communities. Rebuilding destroyed infrastructure could take years and cost billions, a daunting task for a nation already ravaged by war.

PG&E Wildfire Lawsuit alleges utility negligence, inadequate infrastructure maintenance, and faulty transmission lines, as victims seek compensation. Regulators investigate the blaze, echoing class actions after Victoria's Black Saturday mega-fires and utility oversight failures.

Key Points

PG&E Wildfire Lawsuit alleges utility negligence and power line faults, seeking victim compensation amid investigations.

✅ Alleged failure to maintain transmission infrastructure

✅ Spark reports and regulator filings before blaze erupted

✅ Class action parallels with Australia's Black Saturday

Victims of California's most destructive wildfire have filed a lawsuit accusing Pacific Gas & Electric Co. of causing the massive blaze, a move that follows the utility's 2018 Camp Fire guilty plea in a separate case.

The suit filed on Tuesday in state court in California accuses the utility of failing to maintain its infrastructure and properly inspect and manage its power transmission lines, amid prior reports that power lines may have sparked fires in California.

The utility's president said earlier the company doesn't know what caused the fire, but is cooperating with the investigation by state agencies, and other utilities such as Southern California Edison have faced wildfire lawsuits in California.

PG&E told state regulators last week that it experienced a problem with a transmission line in the area of the fire just before the blaze erupted.

A landowner near where the blaze began said PG&E notified her the day before the wildfire that crews needed to come onto her property because some wires were sparking, and the company later promoted its wildfire assistance program for victims seeking aid.

A massive class action after Australia's last mega-fire, Victoria's Black Saturday in 2009, saw $688.5 million paid in compensation to thousands of claimants affected by the Kilmore-Kinglake and Murrindindi-Marysville fires, partly by electricity company SP Ausnet, and partly by government agencies, while in California PG&E's bankruptcy plan won support from wildfire victims addressing compensation claims.

EU Nuclear Power Dispute strains electricity market reform as Germany resists state aid for French reactors, while Eon urges cooperation to meet the energy transition, low-carbon goals, renewables integration, and cross-border power trade.

Key Points

A policy standoff between Germany and France over nuclear energy's role, state aid, and electricity market reforms.

✅ Germany opposes state aid for existing French nuclear plants.

✅ Eon CEO urges compromise to advance market reform and decarbonization.

✅ Cross-border trade shows reliance on French nuclear amid renewables push.

Germany should stop trying to impose its views on nuclear power on the rest of the EU, the head of one of Europe’s largest utilities has warned, as he stressed its importance in the region’s clean energy transition.

Leonhard Birnbaum, chief executive of German energy provider Eon, said Berlin should accept differences of opinion as he signalled his desire for a compromise with France to break a deadlock amid a nuclear power dispute over energy reforms.

Germany this year shut down its final three nuclear power plants as it followed through on a long-held promise to drop the use of the energy source, effectively turning its back on nuclear for now, while France has made it a priority to modernise its nuclear power plants.

The differences are delaying reforms to the region’s electricity market and legislation designed to meet greenhouse gas emissions targets.

One sticking point is Germany’s refusal to back French moves to allow governments to provide state aid to existing power plants, which could enable Paris to support the French nuclear fleet.

The Eon chief, whose company has 48mn customers across Europe, said it would be “better for everyone” if the two countries could approach the dispute with the mindset that “everyone does their part”, even as Germany has at times weighed a U-turn on the nuclear phaseout in recent debates.

“Neither the French will be able to persuade us to use nuclear power, nor we will be able to persuade them not to. That’s why I think we should take a different approach to the discussion,” he added.

Birnbaum said Germany “would do well to be a bit cautious about trying to impose our way on everyone else”. This approach was unlikely to be “crowned with success”.

“The better solution will not come from opposing each other, but from working together.”

Birnbaum made the comments at a press conference announcing Eon’s second-quarter results.

The company raised its profit outlook, predicting adjusted net income of €2.7bn to €2.9bn, and promised to reduce bills for customers as it hailed “diminishing headwinds” following the energy crisis caused by the war in Ukraine.

Birnbaum, whose company owned one of the three German nuclear plants shut down this year, pointed out that French nuclear energy was helping the conversion to a system of renewable energy in Germany at a time when Europe is losing nuclear power just when it needs energy.

This was a reference to Europe’s shared power market that allows countries to buy and sell electricity from one another. 

Germany has been a net importer of French electricity since shutting down its own nuclear plants, which last month prompted the French energy minister Agnès Pannier-Runacher to accuse Berlin of hypocrisy. 

“It’s a contradiction to massively import French nuclear energy while rejecting every piece of EU legislation that recognises the value of nuclear as a low-carbon energy source,” Pannier-Runacher told the German business daily Handelsblatt.

She also criticised Berlin’s drive to use new gas-fired power plants as a “bridge” to its target of being carbon neutral by 2045, even as some German officials contend that nuclear won’t solve the gas issue in the near term, arguing that it created a “credibility problem” for Germany: “Gas is a fossil fuel.”

Berlin officials responded by pointing out that Germany was a net exporter of electricity to France over the winter when its nuclear power stations were struggling to produce because of maintenance problems. 

They added that the country only imported French power because it was cheaper, not because their country was suffering shortages.

Berlin argues that renewable energy is cleaner and safer than nuclear, despite renewable rollout challenges linked to cheap Russian gas and grid expansion, and accuses France of seeking to protect the interests of its nuclear industry.

In Paris, officials see Germany’s resistance to nuclear energy as wrong-headed given the need to fight climate change effectively, and worry it is an attempt to undercut a key aspect of French industrial competitiveness.

Churchill Falls NL-Quebec Agreement boosts hydropower revenues, revises power purchase pricing, expands transmission lines, and integrates Indigenous rights, enabling renewable energy growth, domestic supply, exports, and interprovincial collaboration on infrastructure and utility modernization.

Key Points

A renegotiated hydropower deal reallocating power and advancing projects with Indigenous benefits in NL and Quebec.

✅ Raises Hydro-Quebec price for Churchill Falls electricity

✅ Increases NL power share for domestic use and exports

✅ Commits joint projects and Indigenous participation safeguards

St. John's, Newfoundland and Labrador - In a historic development, Newfoundland and Labrador (NL) and Quebec have reached a tentative agreement over the controversial Churchill Falls hydroelectric project, amid Quebec's electricity ambitions and longstanding regional sensitivities, potentially unlocking hundreds of billions of dollars for the Atlantic province. The deal, announced jointly by Premier Andrew Furey and Quebec Premier François Legault, aims to rectify the decades-long imbalance in the original 1969 contract, which saw NL receive significantly less revenue than Quebec for the province's vast hydropower resources.

The core of the new agreement involves a substantial increase in the price that Hydro-Québec pays for electricity generated at Churchill Falls. This price hike, retroactive to January 1, 2025, is expected to generate billions in additional revenue for NL over the next several decades. The deal also includes provisions for:

• Increased power allocation for NL: The province will gain a larger share of the electricity generated at Churchill Falls, allowing for increased domestic consumption and potential export opportunities through the sale and trade of power across regional markets.
• Joint infrastructure development: Both provinces will collaborate on new energy projects, in line with Hydro-Québec's $185-billion plan to reduce fossil fuel reliance, including potential expansions to the Churchill Falls generating station and the development of new transmission lines.
• Indigenous involvement: The agreement acknowledges the importance of Indigenous rights and seeks to ensure that Indigenous communities in both provinces benefit from the project.

This landmark deal represents a significant victory for NL, which has long argued that the original 1969 contract was grossly unfair. The province has been seeking to renegotiate the terms of the agreement for decades, citing the low price paid for electricity and the significant economic benefits that have accrued to Quebec.

Key Implications:

• Economic Transformation: The influx of revenue from the new Churchill Falls agreement has the potential to significantly transform the economy of NL, though the legacy of Muskrat Falls costs tempers expectations before plans are finalized. The province can invest in critical infrastructure projects, such as healthcare, education, and transportation, as well as support economic diversification initiatives.
• Energy Independence: The increased access to electricity will enhance NL's energy security and reduce its reliance on fossil fuels. This shift towards renewable energy aligns with the province's climate change goals, and in the context of Quebec's no-nuclear stance could attract new investment in sustainable industries.
• Interprovincial Relations: The successful negotiation of this complex agreement demonstrates the potential for constructive collaboration between provinces on major infrastructure projects, as seen in recent NB Power-Hydro-Québec agreements to import more electricity. It sets a precedent for future interprovincial partnerships on issues of shared interest.

Challenges and Considerations:

• Implementation: The successful implementation of the agreement will require careful planning and coordination between the two provinces.
• Environmental Impact: The expansion of hydroelectric generation at Churchill Falls must be carefully assessed for its potential environmental impacts, including the effects on local ecosystems and Indigenous communities.
• Public Consultation: It is crucial that the governments of NL and Quebec engage in meaningful public consultation throughout the implementation process to ensure that the benefits of the agreement are shared equitably across both provinces.

The Churchill Falls agreement marks a turning point in the history of energy development in Canada. It demonstrates the potential for provinces to work together to achieve mutually beneficial outcomes, even as Nova Scotia shifts toward wind and solar after stepping back from the Atlantic Loop, while also addressing historical inequities and ensuring a more equitable distribution of the benefits of natural resources.

RBC Renewable Energy PPA supports a 39 MW Alberta solar project, with Bullfrog Power and BluEarth Renewables, advancing clean energy in a deregulated market through a long-term power purchase agreement in Canada today.

Key Points

A long-term power purchase agreement where RBC buys most output from a 39 MW Alberta solar project via Bullfrog Power.

✅ 39 MW solar build in County of Forty Mile, Alberta

✅ Majority of output purchased by RBC via Bullfrog Power

✅ Supports cost-competitive renewables in deregulated market

The Royal Bank of Canada says it is the first Canadian bank to sign a long-term renewable energy power purchase agreement, a deal that will support the development of a 39-megawatt, $70-million solar project in southern Alberta, within an energy powerhouse province.

The bank has agreed with green energy retailer Bullfrog Power to buy the majority of the electricity produced by the project, as a recent federal green electricity contract highlights growing demand, to be designed and built by BluEarth Renewables of Calgary.

The project is to provide enough power for over 6,400 homes and the panel installations will cover 120 hectares, amid a provincial renewable energy surge that could create thousands of jobs, the size of 170 soccer fields.

The solar installation is to be built in the County of Forty Mile, a hot spot for renewable power that was also chosen by Suncor Energy Inc. for its $300-million 200-MW wind power project (approved last year and then put on hold during the COVID-19 pandemic), and home to another planned wind power farm in Alberta.

BluEarth says commercial operations at its Burdett and Yellow Lake Solar Project are expected to start up in April 2021, underscoring solar power growth in the province.

Electric Field-Induced Glass Softening reveals a Joule heating anomaly in silicate glass, where anode-side nanoscale alkali depletion drives ionic conduction, localized thermal runaway, melting, and evaporation, challenging homogeneity assumptions and refining materials processing models.

Key Points

An effect where electric fields lower glass softening temperature via nanoscale ionic migration and structural change.

✅ Anode-side alkali depletion creates extreme, localized heating

✅ Thermal runaway melts glass near the anode despite uniform bulk

✅ Findings refine Joule heating models and enable new glass processing

A team of scientists working with electrical currents and silicate glass have been left gobsmacked after the glass appeared to defy a basic physical law, in a field that also explores electricity-from-air devices for novel energy harvesting.

If you pass an electrical current through a material, the way that current generates heat can be described by Joule's first law. It's been observed time and time again, with the temperature always evenly distributed when the material is homogeneous (or uniform).

But not in this recent experiment. A section - and only a section - of silicate glass became so hot that it melted, and even evaporated. Moreover, it did so at a much lower temperature than the boiling point of the material.

The boiling point of pure silicate glass is 2,230 degrees Celsius (4,046 degrees Fahrenheit). The hottest temperature the researchers recorded in a homogeneous piece of silicate glass during the experiment was 1,868.7 degrees Celsius.

Say whaaaat.

"The calculations did not add up to explain what we were seeing as simply standard Joule heating," said engineer and materials scientist Himanshu Jain of Lehigh University.

"Even under very moderate conditions, we observed fumes of glass that would require thousands of degrees higher temperature than Joule's law could predict!"

Jain and his colleagues from materials science company Corning Incorporated were investigating a phenomenon they had described in a previous paper. In 2015, they reported that an electric field could reduce the temperature at which glass softens, by as much as a few hundred degrees, a line of inquiry that parallels work on low-cost heat-to-electricity materials in energy research. They called this "electric field-induced softening."

It was certainly a peculiar phenomenon, so they set up another experiment. They put pieces of glass in a furnace, and applied 100 to 200 volts in the form of both alternating and direct currents.

Next, a thin wisp of vapour emanated from the spot where the anode conveying the current contacted the glass.

"In our experiments, the glass became more than a thousand degrees Celsius hotter near the positive side than in the rest of the glass, which was very surprising considering that the glass was totally homogeneous to begin with," Jain said.

This seems to fly in the face of Joule's first law, so the team investigated more closely - and found that the glass wasn't remaining as homogeneous as it started out. The electric field changed the chemistry and the structure of the glass on nanoscale, in just a small section close to the anode.

This region heats faster than the rest of the glass, to the point of becoming a thermal runaway - where an increase in temperature further increases temperature in a blistering feedback loop.

As it turned out, that spot of structural change and dramatic heat resulted in a small area of glass reaching melting point while the rest of the material remained solid.

"Unlike electronically conducting metals and semiconductors, with time the heating of ionically conducting glass becomes extremely inhomogeneous with the formation of a nanoscale alkali-depletion region, such that the glass melts near the anode, even evaporates, while remaining solid elsewhere," the researchers wrote in their paper.

In other words, the material wasn't homogeneous any more, which means the glass heating experiment doesn't exactly change how we apply Joule's first law.

But it's an exciting result, since until now we didn't know a material could actually lose its homogeneity with the application of an electrical current, with possible implications for thin-film heat harvesters in electronics. (The thing is, no one had tried electrically heating glass to these extreme temperatures before.)

So the physical laws of the Universe are still okay, as a piece of glass hasn't broken them. But Joule's first law may need a bit of tweaking to take this effect into account, a reminder that unconventional energy concepts like nighttime solar cells also challenge our intuitions.

And, of course, it's another piece of understanding that could help us in other ways too, including advances in thermoelectric materials that turn waste heat into electricity.

"Besides demonstrating the need to qualify Joule's law," Jain said, "the results are critical to developing new technology for the fabrication and manufacturing of glass and ceramic materials."

The research has been published in Scientific Reports.
