Natural gas crisis looms, study warns

Russia-Ukraine Energy Ceasefire Violations escalate as U.S.-brokered truce frays, with drone strikes, shelling, and grid attacks disrupting gas supply and power infrastructure across Kursk, Luhansk, Sumy, and Dnipropetrovsk, prompting sanctions calls.

Key Points

Alleged breaches of a U.S.-brokered truce, with both sides striking power grids, gas lines, and critical energy nodes.

✅ Drone and artillery attacks reported on power and gas assets

✅ Both sides accuse each other of breaking truce terms

✅ U.S. mediation faces verification and compliance hurdles

Russia and Ukraine have traded fresh accusations regarding violations of a fragile energy ceasefire, brokered by the United States, which both sides had agreed to last month. These new allegations highlight the ongoing tensions between the two nations and the challenges involved in implementing a truce amid global energy instability in such a complex and volatile conflict.

The U.S.-brokered ceasefire had initially aimed to reduce the intensity of the fighting, specifically in the energy sector, where both sides had previously targeted each other’s infrastructure. Despite this agreement, the accusations on Wednesday suggest that both Russia and Ukraine have continued their attacks on each other's energy facilities, a crucial aspect of the ceasefire’s terms.

Russia’s Ministry of Defence claimed that Ukrainian forces had launched drone and shelling attacks in the western Kursk region, cutting power to over 1,500 homes. This attack allegedly targeted key infrastructure, leaving several localities without electricity. Additionally, in the Russian-controlled part of Ukraine's Luhansk region, a Ukrainian drone strike hit a gas distribution station, severely disrupting the gas supply for over 11,000 customers in the area around Svatove.

In response, Ukrainian President Volodymyr Zelensky accused Russia of breaking the ceasefire. He claimed that Russian drone strikes had targeted an energy substation in Ukraine’s Sumy region, while artillery fire had damaged a power line in the Dnipropetrovsk region, leaving nearly 4,000 consumers without power even as Ukraine increasingly leans on electricity imports to stabilize the grid. Ukraine's accusations painted a picture of continued Russian aggression against critical energy infrastructure, a strategy that had previously been a hallmark of Russia’s broader military operations in the war.

The U.S. had brokered the energy truce as a potential stepping stone toward a more comprehensive ceasefire agreement. However, the repeated violations raise questions about the truce’s viability and the broader prospects for peace between Russia and Ukraine. Both sides are accusing each other of undermining the agreement, which had already been delicate due to previous suspicions and mistrust. In particular, the U.S. administration, led by President Donald Trump, has expressed impatience with the slow progress in moving toward a lasting peace, amid debates over U.S. national energy security priorities.

Kremlin spokesperson Dmitry Peskov defended Russia’s stance, emphasizing that President Vladimir Putin had shown a commitment to peace by agreeing to the energy truce, despite what he termed as daily Ukrainian attacks on Russian infrastructure. He reiterated that Russia would continue to cooperate with the U.S., even though the Ukrainian strikes were ongoing. This perspective suggests that Russia remains committed to the truce but views Ukraine’s actions as violations that could potentially derail efforts to reach a more comprehensive ceasefire.

On the other hand, President Zelensky argued that Russia was not adhering to the terms of the ceasefire. He urged the U.S. to take a stronger stance against Russia, including increasing sanctions on Moscow as punishment for its violations. Zelensky’s call for heightened sanctions is a continuation of his efforts to pressure international actors, particularly the U.S. and European countries, to provide greater energy security support for Ukraine’s struggle and to hold Russia accountable for its actions.

The ceasefire’s fragility is also reflected in the differing views between Ukraine and Russia on what constitutes a successful resolution. Ukraine had proposed a full 30-day ceasefire, but President Putin declined, raising concerns about monitoring and verifying compliance with the terms. This disagreement suggests that both sides are not entirely aligned on what a peaceful resolution should look like and how it can be realistically achieved.

The situation is complicated by the broader context of the war, which has now dragged on for over three years. The conflict has seen significant casualties, immense destruction, and deep geopolitical ramifications. Both countries are heavily reliant on their energy infrastructures, making any attack on these systems not only a military tactic but also a form of economic warfare. Energy resources, including electricity and natural gas, have become central to the ongoing conflict, with both sides using them to exert pressure on the other amid Europe's deepening energy crisis that reverberates beyond the battlefield.

As of now, it remains unclear whether the recent violations of the energy ceasefire will lead to a breakdown of the truce or whether the United States will intervene further to restore compliance, even as Ukraine prepares for winter amid energy challenges. The situation remains fluid, and the international community continues to closely monitor the developments. The U.S., which played a central role in brokering the energy ceasefire, has made it clear that it expects both sides to uphold the terms of the agreement and work toward a more permanent cessation of hostilities.

The continued accusations between Russia and Ukraine regarding the breach of the energy ceasefire underscore the challenges of negotiating peace in such a complex and entrenched conflict. While both sides claim to be upholding their commitments, the reality on the ground suggests that reaching a full and lasting peace will require much more than temporary truces. The international community, particularly the U.S., will likely continue to push for stronger actions to enforce compliance and to prevent the conflict from further escalating. The outcome of this dispute will have significant implications for both countries and the broader European energy landscape and security landscape.

Ukraine-Spain Power Aid highlights swift international solidarity as Kyiv offers grid restoration expertise to Spain after unprecedented blackouts, aiding energy infrastructure recovery, interconnectors, and emergency response while operators restore power across Spain and Portugal.

Key Points

Ukraine sends grid experts to help Spain recover from blackouts, restore power, and reinforce energy infrastructure.

✅ Ukraine offers grid restoration expertise and emergency support.

✅ Partial power restored; cause of blackouts under investigation.

✅ EU funding and Ukrenergo bolster infrastructure resilience.

In a remarkable display of international solidarity, Ukraine has extended assistance to Spain as the country grapples with widespread power outages. On April 28, 2025, Spain and neighboring Portugal experienced unprecedented blackouts that disrupted daily life, including internet connectivity and subway operations. The two nations declared a state of emergency as they worked to restore power.

Ukraine's Offer of Assistance

In response to the crisis, Ukrainian President Volodymyr Zelensky reached out to Spanish Prime Minister Pedro Sánchez, offering support to help restore Spain's power grid. Zelensky emphasized Ukraine's extensive experience in managing energy challenges, particularly in fighting to keep the lights on during sustained Russian attacks on its energy infrastructure. He instructed Ukraine’s Energy Minister, Herman Haluschchenko, to mobilize technical experts to assist Spain swiftly. As of April 29, grid operators in both Spain and Portugal reported partial restoration of power, with recovery efforts ongoing. Authorities continue to investigate the cause of the outages. 

Ukraine's Energy Crisis: A Background

Ukraine's offer of assistance is particularly poignant given its own recent struggles with energy security. Throughout 2024, Russia launched numerous aerial strikes targeting Ukraine's energy infrastructure, including strikes on western Ukraine that severely damaged power generation facilities and transmission networks. These attacks led to significant challenges during the winter season, including widespread blackouts and difficulties in heating households, prompting efforts to keep the lights on this winter across the country. Despite these adversities, Ukraine managed to navigate the winter without major power shortages, thanks to rapid repairs and the resilience of its energy sector. 

International Support for Ukraine

The international community has played a crucial role in supporting Ukraine's energy sector, even as U.S. support for grid restoration has shifted, with continued aid from European partners. In July 2024, the European Union allocated nearly $110 million through the KfW Development Bank to modernize high-voltage substations and develop interconnectors with continental Europe's power system. This funding has been instrumental in repairing and restoring equipment damaged by Russian attacks and enhancing the protection of Ukraine's substations. Since the onset of the conflict, Ukraine's energy grid operator, Ukrenergo, has received international assistance totaling approximately €1.5 billion. 

A Gesture of Solidarity

Ukraine's offer to assist Spain underscores the deepening ties between the two nations and reflects a broader spirit of international cooperation. While Spain continues its recovery efforts, the support from Ukraine serves as a reminder of the importance of solidarity, and of Ukraine's electricity reserves that help prevent further outages in times of crisis. As both countries work towards restoring and securing their energy infrastructures, their collaboration highlights the shared challenges and mutual support that define the European community.

Ukraine's proactive stance in offering assistance to Spain amidst the recent blackouts exemplifies the strength of international partnerships and the shared commitment to new energy solutions that overcome energy challenges. As the situation develops, the continued cooperation between nations will be pivotal in ensuring energy security and resilience as winter looms over Ukraine once more.

Cement-Based Conductive Composite transforms concrete into power by energy harvesting via triboelectric nanogenerator action, carbon fibers, and built-in capacitors, enabling net-zero buildings and self-sensing structural health monitoring from footsteps, wind, rain, and waves.

Key Points

A carbon fiber cement that harvests and stores energy as electricity, enabling net-zero, self-sensing concrete.

✅ Uses carbon fibers to create a conductive concrete matrix

✅ Acts as a triboelectric nanogenerator and capacitor

✅ Enables net-zero, self-sensing structural health monitoring

Engineers from South Korea have invented a cement-based composite that can be used in concrete to make structures that generate and store electricity through exposure to external mechanical energy sources like footsteps, wind, rain and waves, and even self-powering roads concepts.

By turning structures into power sources, the cement will crack the problem of the built environment consuming 40% of the world’s energy, complementing vehicle-to-building energy strategies across the sector, they believe.

Building users need not worry about getting electrocuted. Tests showed that a 1% volume of conductive carbon fibres in a cement mixture was enough to give the cement the desired electrical properties without compromising structural performance, complementing grid-scale vanadium flow batteries in the broader storage landscape, and the current generated was far lower than the maximum allowable level for the human body.

Researchers in mechanical and civil engineering from from Incheon National University, Kyung Hee University and Korea University developed a cement-based conductive composite (CBC) with carbon fibres that can also act as a triboelectric nanogenerator (TENG), a type of mechanical energy harvester.

They designed a lab-scale structure and a CBC-based capacitor using the developed material to test its energy harvesting and storage capabilities, similar in ambition to gravity storage approaches being scaled.

“We wanted to develop a structural energy material that could be used to build net-zero energy structures that use and produce their own electricity,” said Seung-Jung Lee, a professor in Incheon National University’s Department of Civil and Environmental Engineering, noting parallels with low-income housing microgrids in urban settings.

“Since cement is an indispensable construction material, we decided to use it with conductive fillers as the core conductive element for our CBC-TENG system,” he added.

The results of their research were published this month in the journal Nano Energy.

Apart from energy storage and harvesting, the material could also be used to design self-sensing systems that monitor the structural health and predict the remaining service life of concrete structures without any external power, which is valuable in industrial settings where hydrogen-powered port equipment is being deployed.

“Our ultimate goal was to develop materials that made the lives of people better and did not need any extra energy to save the planet. And we expect that the findings from this study can be used to expand the applicability of CBC as an all-in-one energy material for net-zero energy structures,” said Prof. Lee, pointing to emerging circular battery recycling pathways for net-zero supply chains.

Publicising the research, Incheon National University quipped: “Seems like a jolting start to a brighter and greener tomorrow!”

Ontario Electricity Capacity Gap threatens reliability as IESO forecasts shortfalls from the Pickering shutdown and rapid electrification, requiring new low-emission nuclear generation to meet net-zero targets, maintain baseload, and stabilize the grid.

Key Points

Expected 2030 shortfalls from Pickering closure and electrification, requiring new low-emission nuclear to meet net-zero.

✅ IESO projects a 3.6-9.5 GW capacity gap by 2030

✅ Pickering shutdown removes baseload, stressing reliability

✅ New low-emission nuclear needed to meet net-zero targets

Ontario faces an electricity supply shortage and reliability risks in the next four to eight years and will not meet net-zero objectives without building new low-emission, nuclear generation starting as soon as possible, according to a report released yesterday by the Power Workers' Union (PWU). The capacity needed to fill the expected supply gap will be equivalent to doubling the province's planned nuclear fleet in eight years.

The planned closure of the Pickering nuclear power plant in 2025 and the increase in demand from electrification of the economy are the drivers behind a capacity gap in 2030 of at least 3.6 GW which could widen to as much as 9.5 GW, Electrification Pathways for Ontario to Reduce Emissions, finds. Ontario's Independent Electricity System Operator (IESO) has since 2013 been forecasting a significant gap in the province's electricity supply due the closure of Pickering, but has been underestimating the impact of electrification, the report says.

In addition, the electrification of buildings, transport and industry sectors that will be needed to achieve goals of net-zero emissions by 2050 that being set by the federal government and civil society will see the province's electricity demand increase by at least 130% over current planning forecasts, and potentially by over 190%. Leveraging electricity, natural gas and hydrogen synergies can reduce supply needs, but 55 GW of new electricity capacity, including new large-scale nuclear plants, will still be needed by 2050 - four times Ontario's current nuclear and hydro assets - the report finds.

These findings underscore the urgent need for a paradigm shift in Ontario's electricity planning and procurement process, the authors say, adding that immediate action is needed both to mitigate the system reliability risks and enable the significant societal benefits needed to pursue net-zero objectives. Planning for procurement to replace Pickering's capacity, or to pursue life extension options, must begin as soon as possible.

"Policymakers around the world realise climate change can't be tackled without nuclear. Ontario's nuclear fleet has delivered emissions reductions for over 50 years," PWU President Jeff Parnell said. "In fact, without building new nuclear units, Ontario will miss its emission reduction targets and carbon emissions from electricity generation will rise dramatically, as explored in why Ontario's power could get dirtier today."

"This report clearly shows that Ontario cannot sustain the low-carbon status of its hydro and nuclear-based electricity system, decarbonise its economy and meet its carbon reduction targets without new nuclear or continued operation at Pickering in the near term. Most disturbing is the fact that we are already well behind and needed to start planning for this capacity yesterday," he said.

The six operating Candu reactors at Ontario Power Generation's Pickering plant have been kept in operation to provide baseload electricity during the refurbishment of units at the Darlington and Bruce plants. Currently, the company plans to shut down Pickering units 1 and 4 in 2024 and units 5 to 8 in 2025, even as Ontario moves to refurbish Pickering B to extend life.

Pickering Nuclear Alert Error prompts Ontario investigation into the Alert Ready emergency alert system, Pelmorex safeguards, and public response at Pickering Nuclear Generating Station, including potassium iodide orders and geo-targeted notification issues.

Key Points

A mistaken Ontario emergency alert about the Pickering plant, now under probe for human error and system safeguards.

✅ Investigation led by Emergency Management Ontario

✅ Alert Ready and Pelmorex safeguards under review

✅ KI pill demand surged; geo-targeting questioned

A number of questions still remain a week after an emergency alert was mistakenly sent out to people across Ontario warning of an unspecified incident at the Pickering Nuclear Generating Station. 

The province’s solicitor general has stepped in and says an investigation into the incident should be completed fairly quickly according to the minister.

However, the nuclear scare has still left residents on edge with tens of thousands of people ordering potassium iodide, or KI, pills that protect the body from radioactive elements in the days following the incident.

Here’s what we know and still don’t know about the mistaken Pickering nuclear plant alert:

Who sent the alert?

According to the Alert Ready Emergency Alert System website, the agency works with several federal, provincial and territorial emergency management officials, Environment and Climate Change Canada and Pelmorex, a broadcasting industry and wireless service provider, to send the alerts.

Martin Belanger, the director of public alerting for Pelmorex, a company that operates the alert system, said there are a number of safeguards built in, including having two separate platforms for training and live alerts.

"The software has some steps and some features built in to minimize that risk and to make sure that users will be able to know whether or not they're sending an alert through the... training platform or whether they're accessing the live system in the case of a real emergency," he said.

Only authorized users have access to the system and the province manages that, Belanger said. Once in the live system, features make the user aware of which platform they are using, with various prompts and messages requiring the user's confirmation. There is a final step that also requires the user to confirm their intent of issuing an alert to cellphones, radio and TVs, Belanger said.

Last Sunday, a follow-up alert was sent to cellphones nearly two hours after the original notification, and during separate service disruptions such as a power outage in London residents also sought timely information.

What has the investigation revealed?

It’s still unclear as to how exactly the alert was sent in error, but Solicitor General Sylvia Jones has tapped the Chief of Emergency Management Ontario to investigate.

"It's very important for me, for the people of Ontario, to know exactly what happened on Sunday morning," Jones said.

Jones said initial observations suggest human error was responsible for the alert that was sent out during routine tests of the emergency alert.

“I want to know what happened and equally important, I want some recommendations on insurances and changes we can make to the system to make sure it doesn't happen again,” Jones said.

Jones said she expects the results of the probe to be made public.

Can you unsubscribe from emergency alerts?

It’s not possible to opt out of receiving the alerts, according to the Alert Ready Emergency Alert System website, and Ontario utilities warn about scams to help customers distinguish official notices.

“Given the importance of warning Canadians of imminent threats to the safety of life and property, the CRTC requires wireless service providers to distribute alerts on all compatible wireless devices connected to an LTE network in the target area,” the website reads.

The agency explains that unlike radio and TV broadcasting, the wireless public alerting system is geo-targeted and is specific to the a “limited area of coverage”, and examples like an Alberta grid alert have highlighted how jurisdictions tailor notices for their systems.

“As a result, if an emergency alert reaches your wireless device, you are located in an area where there is an imminent danger.”

The Pickering alert, however, was received by people from as far as Ottawa to Windsor.

Is the Pickering Nuclear Generating Station closing?

The Pickering nuclear plant has been operating since 1971, and had been scheduled to be decommissioned this year, but the former Liberal government -- and the current Progressive Conservative government -- committed to keeping it open until 2024. Decommissioning is now set to start in 2028.

It operates six CANDU reactors, and in contingency planning operators have considered locking down key staff to maintain reliability, generates 14 per cent of Ontario's electricity and is responsible for 4,500 jobs across the region, according to OPG, while utilities such as Hydro One's relief programs have supported customers during broader crises.

What should I do if I receive an emergency alert?

Alert Ready says that if you received an alert on your wireless device it’s important to take action “safely”.

“Stop what you are doing when it is safe to do so and read the emergency alert,” the agency says on their website.

“Alerting authorities will include within the emergency alert the information you need and guidance for any action you are required to take, and insights from U.S. grid pandemic response underscore how critical infrastructure plans intersect with public safety.”

“This could include but is not limited to: limit unnecessary travel, evacuate the areas, seek shelter, etc.”

The wording of last Sunday's alert caused much initial confusion, warning residents within 10 kilometres of the plant of "an incident," though there was no "abnormal" release of radioactivity and residents didn't need to take protective steps, but emergency crews were responding.

“In the event of a real emergency, the wording would be different,” Jones said.
