TVA manager: Utility a leader in cutting emissions

Grid Transformer Waste Heat Recovery turns substations into neighborhood boilers, supplying district heating via heat networks, helping National Grid and SSE cut emissions, boost energy efficiency, and advance low carbon, net zero decarbonization.

Key Points

Grid Transformer Waste Heat Recovery captures substation heat for district heating, cutting emissions and gas use.

✅ Captures waste heat from National Grid transformers

✅ Feeds SSE district heat networks for nearby homes

✅ Cuts carbon, improves efficiency, aligns with net zero

Thousands of homes could soon be warmed by the heat from giant electricity grid transformers for the first time as part of new plans to harness “waste heat” and cut carbon emissions from home heating.

Trials are due to begin on how to capture the heat generated by transmission network transformers, owned by National Grid, to provide home heating for households connected to district heating networks operated by SSE.

Currently, hot air is vented from the giant substations to help cool the transformers that help to control the electricity running through National Grid’s high-voltage transmission lines.

However, if the trial succeeds, about 1,300 National Grid substations could soon act as neighbourhood “boilers”, piping water heated by the substations into nearby heating networks, and on into the thousands of homes that use SSE’s services.

“Electric power transformers generate huge amounts of heat as a byproduct when electricity flows through them. At the moment, this heat is just vented directly into the atmosphere and wasted,” said Nathan Sanders, the managing director of SSE Energy Solutions.

“This groundbreaking project aims to capture that waste heat and effectively turn transformers into community ‘boilers’ that serve local heat networks with a low- or even zero-carbon alternative to fossil-fuel-powered heat sources such as gas boilers, a shift akin to a gas-for-electricity swap in heating markets,” Sanders added.

Alexander Yanushkevich, National Grid’s innovation manager, said the scheme was “essential to achieve net zero” and a “great example of how, taking a whole-system approach, including power-to-gas in Europe precedents, the UK can lead the way in helping accelerate decarbonisation”.

The energy companies believe the scheme could initially reduce heat network carbon emissions by more than 40% compared with fossil gas systems. Once the UK’s electricity system is zero carbon, and with recent milestones where wind was the main source of UK electricity on the grid, the heating solution could play a big role in helping the UK meet its climate targets.

The first trials have begun at National Grid’s specially designed testing site at Deeside in Wales to establish how the waste heat could be used in district heating networks. Once complete, the intellectual property will be shared with smaller regional electricity network owners, which may choose to roll out schemes in their areas.

Tim O’Reilly, the head of strategy at National Grid, said: “We have 1,300 transmission transformers, but there’s no reason why you couldn’t apply this technology to smaller electricity network transformers, too, echoing moves to use more electricity for heat in colder regions.”

Once the trials are complete, National Grid and SSE will have a better idea of how many homes could be warmed using the heat generated by electricity network substations, O’Reilly said, and how the heat can be used in ways that complement virtual power plants for grid resilience.

“The heavier the [electricity] load, which typically reaches a peak at around teatime, the more heat energy the transformer will be able to produce, aligning with times when wind leads the power mix nationally. So it fits quite nicely to when people require heat in the evenings,” he added.

Other projects designed to capture waste heat to use in district heating schemes include trapping the heat generated on the Northern line of London’s tube network to warm homes in Islington, and harnessing the geothermal heat from disused mines for district heating networks in Durham.

Only between 2% and 3% of the UK is connected to a district heating network, but more networks are expected to emerge in the years ahead as the UK tries to reduce the carbon emissions from homes, alongside its nuclear power plans in the wider energy strategy.

Ukraine Nuclear Plant Ownership Proposal outlines U.S. management of Ukrainian reactors amid the Russia-Ukraine war, citing nuclear safety, energy security, and IAEA oversight; Kyiv rejects ownership transfer, especially regarding Zaporizhzhia under Russian control.

Key Points

U.S. control of Ukraine's nuclear plants for safety; Kyiv rejects transfer, citing sovereignty risks at Zaporizhzhia.

✅ U.S. proposal to manage Ukraine's reactors amid war

✅ Kyiv refuses ownership transfer; open to investment

✅ Zaporizhzhia under Russian control raises safety risks

In the midst of the ongoing conflict between Russia and Ukraine, U.S. President Donald Trump has proposed a controversial idea: Ukraine should give its nuclear power plants to the United States for safekeeping and management. This suggestion came during a phone call with Ukrainian President Volodymyr Zelenskyy, wherein Trump expressed the belief that American ownership of these nuclear plants could offer them the best protection amid the ongoing war. But Kyiv, while open to foreign support, has firmly rejected the idea of transferring ownership, especially as the Zaporizhzhia nuclear plant remains under Russian occupation.

Ukraine’s nuclear energy infrastructure has always been a vital component of its power generation. Before the war, the country’s four nuclear plants supplied nearly half of its electricity. As Russia's military forces target Ukraine's energy infrastructure, including power plants and coal mines, international watchdogs like the IAEA have warned of nuclear risks as these nuclear facilities have become crucial to maintaining the nation’s energy stability. The Zaporizhzhia plant, in particular, has attracted international concern due to its size and the ongoing threat of a potential nuclear disaster.

Trump’s Proposal and Ukraine’s Response

Trump’s proposal of U.S. ownership came as a response to the ongoing threats posed by Russia’s occupation of the Zaporizhzhia plant. Trump argued that the U.S., with its expertise in running nuclear power plants, could safeguard these facilities from further damage and potential nuclear accidents. However, Zelenskyy quickly clarified that the discussion was only focused on the Zaporizhzhia plant, which is currently under Russian control. The Ukrainian president emphasized that Kyiv would not entertain the idea of permanently transferring ownership of its nuclear plants, even though they would welcome investment in their restoration and modernization, particularly after the war.

The Zaporizhzhia nuclear plant has been a focal point of geopolitical tensions since Russia's occupation in 2022. Despite being in "cold shutdown" to prevent further risk of explosions, the facility remains a major concern due to its potential to cause a nuclear disaster. Ukrainian officials, along with international observers, have raised alarm about the safety risks posed by the plant, including mines at Zaporizhzhia reported by UN watchdogs, which is situated in a war zone and under the control of Russian forces who are reportedly neglecting proper safety protocols.

The Fear of a Nuclear Provocation

Ukrainians have expressed concerns that Trump’s proposal could embolden Russia to escalate tensions further, even as a potential agreement on power-plant attacks has been discussed by some parties. Some fear that any attempt to reclaim the plant by Ukraine could trigger a Russian provocation, including a deliberate attack on the plant, which would have catastrophic consequences for both Ukraine and the broader region. The analogy is drawn with the destruction of the Nova Kakhovka dam, which Ukraine accuses Russia of sabotaging, an act that severely disrupted water supplies to the Zaporizhzhia plant. Ukrainian military officials, including Ihor Romanenko, a former deputy head of Ukraine’s armed forces, warned that Trump’s suggestion might be an exploitation of Ukraine’s vulnerable position in the ongoing war.

Despite these fears, there are some voices within Ukraine, including former employees of the Zaporizhzhia plant, who believe that a deliberate attack by Russian forces is unlikely. They argue that the Russian military needs the plant in functioning condition for future negotiations, with Russia building new power lines to reactivate the site as part of that calculus, and any damage could reduce its value in such exchanges. However, the possibility of Russian negligence or mismanagement remains a significant risk.

The Strategic Role of Ukraine's Nuclear Plants

Ukraine's nuclear plants were a cornerstone of the country’s energy sector long before the conflict began. In recent years, as Ukraine lost access to coal resources in the Donbas region due to Russian occupation, nuclear power became even more vital, alongside a growing focus on wind power to improve resilience. The country’s reliance on these plants grew as Russia launched a sustained campaign to destroy Ukraine’s energy infrastructure, including attacks on nuclear power stations.

The Zaporizhzhia plant, in particular, holds strategic importance not only due to its size but also because of its location in southeastern Ukraine, an area that has been at the heart of the conflict. Despite being in Russian hands, the plant’s reactors have been safely shut down, reducing the immediate risk of a nuclear explosion. However, the plant’s future remains uncertain, as Russia’s long-term control over it could disrupt Ukraine’s energy security for years to come.

Wider Concerns About Aging Nuclear Infrastructure

Beyond the geopolitical tensions, there are broader concerns about the aging infrastructure of Ukraine's nuclear power plants. International watchdogs, including the environmentalist group Bankwatch, have criticized these facilities as “zombie reactors” due to their outdated designs and safety risks. Experts have called for Ukraine to decommission some of these reactors, fearing that they are increasingly unsafe, especially in the context of a war.

However, Ukrainian officials, including Petro Kotin, head of Energoatom (Ukraine's state-owned nuclear energy company), argue that these reactors are still functional and critical to Ukraine's energy needs. The ongoing conflict, however, complicates efforts to modernize and secure these facilities, which are increasingly vulnerable to both physical damage and potential nuclear hazards.

The Global Implications

Trump's suggestion to take control of Ukraine's nuclear power plants has raised significant concerns on the international stage. Some fear that such a move could set a dangerous precedent for nuclear security and sovereignty. Others see it as an opportunistic proposal that exploits Ukraine's wartime vulnerability.

While the future of Ukraine's nuclear plants remains uncertain, one thing is clear: these facilities are now at the center of a geopolitical struggle that could have far-reaching consequences for the energy security of Europe and the world. The safety of these plants and their role in Ukraine's energy future will remain a critical issue as the war continues and as Ukraine navigates its relations with both the U.S. and Russia, with the grid even having resumed electricity exports at times.

BC Hydro COVID-19 Relief offers electricity bill credits for laid-off workers and small business support, announced by Premier John Horgan, while FortisBC customers face deferrals and billing arrangements across Kelowna, Okanagan, and West Kootenay.

Key Points

BC Hydro COVID-19 Relief gives bill credits to laid-off residents; FortisBC offers deferrals and payment plans.

✅ Credit equals 3x average monthly bill for laid-off BC Hydro users

✅ Small businesses on BC Hydro get three months bill forgiveness

✅ FortisBC waives late fees, no disconnections, offers deferrals

On April 1, B.C. Premier John Horgan announced relief for BC Hydro customers who are facing bills after being laid-off during the economic shutdown due to the COVID-19 epidemic, while the utility also explores time-of-use rates to manage demand.

“Giving people relief on their power bills lets them focus on the essentials, while helping businesses and encouraging critical industry to keep operating,” he said.

BC Hydro residential customers in the province who have been laid off due to the pandemic will see a credit for three times their average monthly bill and, similar to Ontario's pandemic relief fund, small businesses forced to close will have power bills forgiven for three months.

But a large region of the province which gets its power from FortisBC will not have the same bail out.

FortisBC is the electricity provider to the tens of thousands who live and work in the Silmikameen Valley on Highway 3, the city of Kelowna, the Okanagan Valley south from Penticton, the Boundary region along the U.S. border. as well as West Kootenay communities.

“We want to make sure our customers are not worried about their FortisBC bill,” spokesperson Nicole Brown said.

FortisBC customers will still be on the hook for bills despite measures being taken to keep the lights on, even as winter disconnection pressures have been reported elsewhere.

Recent storm response by BC Hydro also highlights how crews have kept electricity service reliable during recent atypical events.

“We’ve adjusted our billing practices so we can do more,” she said. “We’ve discontinued our late fees for the time being and no customer will be disconnected for any financial reason.”

Brown said they will work one-on-one with customers to help find a billing arrangement that best suits their needs, aligning with disconnection moratoriums seen in other jurisdictions.

Those arrangement, she said, could include a “deferral, an equal payment plan or other billing options,” similar to FortisAlberta's precautions announced in Alberta.

Global News inquired with the Premier’s office why FortisBC customers were left out of Wednesday’s announcement and were deferred to the Ministry of Energy, Mines and Petroleum Resources.

The Ministry referred us back to FortisBC on the issue and offered no other comment, even as peak rates for self-isolating customers remained unchanged in parts of Ontario.

“We’re examining all options of how we can further help our customers and look forward to learning more about the program that BC Hydro is offering,” Brown said.

Disappointed FortisBC customers took to social media to vent about the disparity.

Bangladesh Rooppur Nuclear Power Plant advances nuclear energy with IAEA support and ROSATOM construction, boosting energy security, baseload capacity, and grid reliability; 2400 MW units aid development, regulatory compliance, and newcomer infrastructure milestones.

Key Points

A 2400 MW nuclear project in Rooppur, built with IAEA guidance and ROSATOM, to boost Bangladesh's reliable power.

✅ Two units totaling 2400 MW for stable baseload supply

✅ IAEA Milestones and INIR reviews guide safe deployment

✅ ROSATOM builds; national regulator strengthens oversight

The beginning of construction at Bangladesh’s first nuclear power reactor on 30 November 2017 marked a significant milestone in the decade-long process to bring the benefits of nuclear energy to the world’s eighth most populous country. The IAEA has been supporting Bangladesh on its way to becoming the third ‘newcomer’ country to nuclear power in 30 years, following the United Arab Emirates in 2012 and Belarus in 2013.

Bangladesh is in the process of implementing an ambitious, multifaceted development programme to become a middle-income country by 2021 and a developed country by 2041. Vastly increased electricity production, with the goal of connecting 2.7 million more homes to the grid by 2021, is a cornerstone of this push for development, and nuclear energy will play a key role in this area, said Mohammad Shawkat Akbar, Managing Director of Nuclear Power Plant Company Bangladesh Limited. Bangladesh is also working to diversify its energy supply to enhance energy security, reduce its dependence on imports and on its limited domestic resources, he added.

#google# In the region, India's nuclear program is taking steps to get back on track, underscoring broader momentum.

“Bangladesh is introducing nuclear energy as a safe, environmentally friendly and economically viable source of electricity generation,” said Akbar.  The plant in Rooppur, 160 kilometres north-west of Dhaka, will consist of two units, with a combined power capacity of 2400 MW(e). It is being built by a subsidiary of Russia’s State Atomic Energy Corporation ROSATOM. The first unit is scheduled to come online in 2023 and the second in 2024, reflecting progress similar to the UK's latest nuclear power station developments.  “This project will enhance the development of the social, economic, scientific and technological potential of the country,” Akbar said.

The country’s goal of increased electricity production via nuclear energy will soon be a reality, Akbar said. “For 60 years, Bangladesh has had a dream of building its own nuclear power plant. The Rooppur Nuclear Power Plant will provide not only a stable baseload of electricity, but it will enhance our knowledge and allow us to increase our economic efficiency.

Milestones for nuclear

Bangladesh is among around 30 countries that are considering, planning or starting the introduction of nuclear power, with milestones at nuclear projects worldwide offering context for this progress. The IAEA assists them in developing their programmes through the Milestones Approach — a methodology that provides guidance on working towards the establishment of nuclear power in a newcomer country, including the associated infrastructure. It focuses on pointing out gaps, if any, in countries’ progress towards the introduction of nuclear power.

The IAEA has been supporting Bangladesh in developing its nuclear power infrastructure, including in establishing a regulatory framework and developing a radioactive waste-management system. This support has been delivered under the IAEA technical cooperation programme and is partially funded through the Peaceful Uses Initiative.

Nuclear infrastructure is multifaceted, containing governmental, legal, regulatory and managerial components, in addition to the physical infrastructure. The Milestones Approach consists of three phases, with a milestone to be reached at the end of each.

The first phase involves considerations before a decision is taken to start a nuclear power programme and concludes with the official commitment to the programme. The second phase entails preparatory work for the contracting and construction of a nuclear power plant, as seen in Bulgaria's nuclear project planning, ending with the commencement of bids or contract negotiations for the construction. The final phase includes activities to implement the nuclear power plant, such as the final investment decision, contracting and construction. The duration of these phases varies by country, but they typically take between 10 and 15 years.

“The IAEA Milestones Approach is a guiding document and the Integrated Work Plan (IWP) is the important means of bringing all of the stakeholders in Bangladesh together to ensure the fulfilment of all safety, security, and safeguards requirements of the Rooppur NPP project,” said Akbar. “This IWP enabled Bangladesh to develop a holistic approach to implementing IAEA guidance as well as cooperating with national stakeholders and other bilateral partners towards the development of a national nuclear power programme.”

INIR Mission

The Integrated Nuclear Infrastructure Review (INIR) is a holistic peer review to assist Member States in assessing the status of their national infrastructure for introducing nuclear power. The IAEA completed its first INIR mission to Bangladesh in November 2011, making recommendations on how to develop a plan to establish the nuclear infrastructure. Nearly five years later, in May 2016, a follow-up mission was conducted, which noted the progress made — Bangladesh had established a nuclear regulatory body, had chosen a site for the power plant and had completed site characterization and environmental impact assessment.

“The IAEA and other bodies, including those from experienced countries, can and do provide support, but the responsibility for safety and security will lie with the Government,” said Dohee Hahn, Director of the IAEA’s Division of Nuclear Power, at the ceremony for the pouring of the first nuclear safety-related concrete at Rooppur on 30 November 2017. “The IAEA stands ready to continue supporting Bangladesh in developing a safe, secure, peaceful and sustainable nuclear power programme.”

Negative Electricity Prices in France signal oversupply from wind and solar, stressing the wholesale market and grid. Better storage, demand response, and interconnections help balance renewables and stabilize prices today.

Key Points

They occur when renewable output exceeds demand, pushing power prices below zero as excess energy strains the grid.

✅ Driven by wind and solar surges with low demand

✅ Challenges thermal plants; erodes margins at negative prices

✅ Needs storage, demand response, and cross-border interties

France has recently experienced an unusual and unprecedented situation in its electricity market: negative electricity prices. This development, driven by a significant influx of renewable energy sources, highlights the evolving dynamics of energy markets as countries increasingly rely on clean energy technologies. The phenomenon of negative pricing reflects both the opportunities and renewable curtailment challenges associated with the integration of renewable energy into national grids.

Negative electricity prices occur when the supply of electricity exceeds demand to such an extent that producers are willing to pay consumers to take the excess energy off their hands. This situation typically arises during periods of high renewable energy generation coupled with low energy demand. In France, this has been driven primarily by a surge in wind and solar power production, which has overwhelmed the grid and created an oversupply of electricity.

The recent surge in renewable energy generation can be attributed to a combination of favorable weather conditions and increased capacity from new renewable energy installations. France has been investing heavily in wind and solar energy as part of its commitment to reducing greenhouse gas emissions and transitioning towards a more sustainable energy system, in line with renewables surpassing fossil fuels in Europe in recent years. While these investments are essential for achieving long-term climate goals, they have also led to challenges in managing energy supply and demand in the short term.

One of the key factors contributing to the negative prices is the variability of renewable energy sources. Wind and solar power are intermittent by nature, meaning their output can fluctuate significantly depending on weather conditions, with solar reshaping price patterns in Northern Europe as deployment grows. During times of high wind or intense sunshine, the electricity generated can far exceed the immediate demand, leading to an oversupply. When the grid is unable to store or export this excess energy, prices can drop below zero as producers seek to offload the surplus.

The impact of negative prices on the energy market is multifaceted. For consumers, negative prices can lead to lower energy costs as wholesale electricity prices fall during oversupply, and even potential credits or payments from energy providers. This can be a welcome relief for households and businesses facing high energy bills. However, negative prices can also create financial challenges for energy producers, particularly those relying on conventional power generation methods. Fossil fuel and nuclear power plants, which have higher operating costs, may struggle to compete when prices are negative, potentially affecting their profitability and operational stability.

The phenomenon also underscores the need for enhanced energy storage and grid management solutions. Excess energy generated from renewable sources needs to be stored or redirected to maintain grid stability and avoid negative pricing situations. Advances in battery storage technology, such as France's largest battery storage platform, and improvements in grid infrastructure are essential to addressing these challenges and optimizing the integration of renewable energy into the grid. By developing more efficient storage solutions and expanding grid capacity, France can better manage fluctuations in renewable energy production and reduce the likelihood of negative prices.

France's experience with negative electricity prices is part of a broader trend observed in other countries with high levels of renewable energy penetration. Similar situations have occurred in Germany, where solar plus storage is now cheaper than conventional power, the United States, and other regions where renewable energy capacity is rapidly expanding. These instances highlight the growing pains associated with transitioning to a cleaner energy system and the need for innovative solutions to balance supply and demand.

The French government and energy regulators are closely monitoring the situation and exploring measures to mitigate the impact of negative prices. Policy adjustments, market reforms, and investments in energy infrastructure are all potential strategies to address the challenges posed by high renewable energy generation. Additionally, encouraging the development of flexible demand response programs and enhancing grid interconnections with neighboring countries can help manage excess energy and stabilize prices.

In the long term, the rise of renewable energy and the occurrence of negative prices represent a positive development for the energy transition. They indicate progress towards cleaner energy sources and a more sustainable energy system. However, managing the associated challenges is crucial for ensuring that the transition is smooth and economically viable for all stakeholders involved.

In conclusion, the recent instance of negative electricity prices in France highlights the complexities of integrating renewable energy into the national grid. While the phenomenon reflects the success of France’s efforts to expand its renewable energy capacity, it also underscores the need for advanced grid management and storage solutions. As the country continues to navigate the transition to a more sustainable energy system, addressing these challenges will be essential for maintaining a stable and efficient energy market. The experience serves as a valuable lesson for other nations undergoing similar transitions and reinforces the importance of innovation and adaptability in the evolving energy landscape.
