Maine leaders call for tougher mercury limits

Maritime Link HVDC Transmission connects Newfoundland and Nova Scotia to the North American grid, enabling renewable energy imports, subsea cable interconnection, Muskrat Falls hydro power delivery, and lower carbon emissions across Atlantic Canada.

Key Points

A 500 MW HVDC intertie linking Newfoundland and Nova Scotia to deliver Muskrat Falls hydro power.

✅ 500 MW capacity using twin 170 km subsea HVDC cables

✅ Interconnects Newfoundland and Nova Scotia to the North American grid

✅ Enables Muskrat Falls hydro imports, cutting CO2 and costs

For the first time, electricity has been sent between Newfoundland and Nova Scotia through the new Maritime Link.

The 500-megawatt transmission line — which connects Newfoundland to the North American energy grid for the first time and echoes projects like the New England Clean Power Link underway — was tested Friday.

"This changes not only the energy options for Newfoundland and Labrador but also for Nova Scotia and Atlantic Canada," said Rick Janega, the CEO of Emera Newfoundland and Labrador, which owns the link.

"It's an historic event in our eyes, one that transforms the electricity system in our region forever."

'On time and on budget'

It will eventually carry power from the Muskrat Falls hydro project in Labrador, where construction is running two years behind schedule and $4 billion over budget, a context in which the Manitoba Hydro line to Minnesota has also faced delay, to Nova Scotia consumers. It was supposed to start producing power later this year, but the new deadline is 2020 at the earliest.

The project includes two 170-kilometre subsea cables across the Cabot Strait between Cape Ray in southwestern Newfoundland and Point Aconi in Cape Breton.

The two cables, each the width of a two-litre pop bottle, can carry 250 megawatts of high voltage direct current, and rest on the ocean floor at depths up to 470 metres.

The Maritime Link also includes almost 50 kilometres of overland transmission in Nova Scotia and more than 300 kilometres of overland transmission in Newfoundland, paralleling milestones on Site C transmission work in British Columbia.

The link won't go into commercial operation until January 1.

Janega said the $1.6-billion project is on time and on budget.

"We're very pleased to be in a position to be able to say that after seven years of working on this. It's quite an accomplishment," he said.

Once in service, the link will improve electrical interconnections between the Atlantic provinces, aligning with climate adaptation guidance for Canadian utilities.

"For Nova Scotia it will allow it to achieve its 40 per cent renewable energy target in 2020. For Newfoundland it will allow them to shut off the Holyrood generating station, in fact using the Maritime Link in advance of the balance of the project coming into service," Janega said.

Karen Hutt, president and CEO of Nova Scotia Power, which is owned by Emera Inc., calls it a great day for Nova Scotia.

"When it goes into operation in January, the Maritime Link will benefit Nova Scotia Power customers by creating a more stable and secure system, helping reduce carbon emissions, and enabling NSP to purchase power from new sources," Hutt said in a statement.

Ukraine Power Grid Attacks disrupt critical infrastructure as missiles and drones strike power plants, substations, and lines, causing blackouts. Emergency repairs, international aid, generators, and renewables bolster resilience and keep hospitals and water running.

Key Points

Russian strikes on Ukraine's power infrastructure cause blackouts; repairs and aid sustain hospitals and water.

✅ Missile and drone strikes target plants, substations, and lines.

✅ Crews restore power under fire; air defenses protect sites.

✅ Allies supply equipment, generators, and grid repair expertise.

Ukraine is facing an ongoing battle to maintain its electrical grid in the wake of relentless Russian attacks targeting power plants and energy infrastructure. These attacks, which have intensified in the last year, are part of Russia's broader strategy to weaken Ukraine's ability to function amid the ongoing war. Power plants, substations, and energy lines have become prime targets, with Russian forces using missiles and drones to destroy critical infrastructure, as western Ukraine power outages have shown, leaving millions of Ukrainians without electricity and heating during harsh winters.

The Ukrainian government and energy companies are working tirelessly to repair the damage and prevent total blackouts, while also trying to ensure that civilians have access to vital services like hospitals and water supplies. Ukraine has received support from international allies in the form of technical assistance and equipment to help strengthen its power grid, and electricity reserve updates suggest outages can be avoided if no new strikes occur. However, the ongoing nature of the attacks and the complexity of repairing such extensive damage make the situation extraordinarily difficult.

Despite these challenges, Ukraine's resilience is evident, even as winter pressures on the battlefront intensify operations. Energy workers are often working under dangerous conditions, risking their lives to restore power and prevent further devastation. The Ukrainian government has prioritized the protection of energy infrastructure, with military forces being deployed to safeguard workers and critical assets.

Meanwhile, the international community continues to support Ukraine through financial and technical aid, though some U.S. support programs have ended recently, as well as providing temporary power solutions, like generators, to keep essential services running. Some countries have even sent specialized equipment to help repair damaged power lines and energy plants more quickly.

The humanitarian consequences of these attacks are severe, as access to electricity means more than just light—it's crucial for heating, cooking, and powering medical equipment. With winter temperatures often dropping below freezing, plans to keep the lights on are vital to protect vulnerable communities, and the lack of reliable energy has put many lives at risk.

In response to the ongoing crisis, Ukraine has also focused on enhancing its energy independence, seeking alternatives to Russian-supplied energy. This includes exploring renewable energy sources, such as solar and wind power, and new energy solutions adopted by communities to overcome winter blackouts, which could help reduce reliance on traditional energy grids and provide more resilient options in the future.

The battle for energy infrastructure in Ukraine illustrates the broader struggle of the country to maintain its sovereignty and independence in the face of external aggression. The destruction of power plants is not only a military tactic but also a psychological one—meant to instill fear and disrupt daily life. However, the unwavering spirit of the Ukrainian people, alongside international support, including Ukraine's aid to Spain during blackouts as one example, continues to ensure that the fight to "keep the lights on" is far from over.

As Ukraine works tirelessly to repair its energy grid, it also faces the challenge of preparing for the long-term impact of these attacks. The ongoing war has highlighted the importance of securing energy infrastructure in modern conflicts, and the world is watching as Ukraine's resilience in this area could serve as a model for other nations facing similar threats.

Ukraine’s energy struggle is far from over, but its determination to keep the lights on remains a beacon of hope and defiance in the face of ongoing adversity.

Sub-Saharan Africa Energy Access faces critical deficits; SDG7, clean energy finance, off-grid solar, and microgrids drive electrification for health, education, and economy amid World Bank and IEA efforts to expand reliable, affordable power.

Key Points

Reliable, affordable power in sub-Saharan Africa via renewables, off-grid solar, and SDG7-led electrification.

✅ SDG7 targets universal, modern energy access by 2030

✅ Off-grid solar and microgrids boost rural electrification

✅ Health, education, and business depend on reliable power

Sub-Saharan Africa has an electricity problem. While the world as a whole has made great strides when it comes to providing access to electricity and moving toward universal electricity access worldwide (the world average is now 90 per cent with access, up from 83 per cent in 2010), southern and western African states still lag far behind.

According to Tracking SDG7: The Energy Progress Report, produced by a consortium of organisations including the World Bank, the International Energy Agency and the World Health Organization, 759 million people were without electricity in 2019 and threequarters of them were based in sub-Saharan Africa. At just seven per cent, South Sudan had the lowest access figures; Chad, Burundi and Malawi were only marginally higher. What’s more, due to a combination of factors, the situation is getting worse. In total, the region’s access deficit increased from 556 million people in 2010 to 570 million people in 2019.

These days, being without electricity has an impact on every sphere of life. The Covid-19 pandemic only served to put this into sharper relief. Intermittent electricity meant vaccination doses that rely on cold storage were impossible to deliver and, as more than 70 per cent of the health facilities in sub-Saharan Africa have no access to reliable electricity, the problem was vast. But even without a global pandemic, having no power stymies opportunity in every field, from education to economics.

French photojournalist Pascal Maitre, who has spent much of his career writing about sub-Saharan Africa, wanted to document the problems faced by people in areas with no electricity. He thought particularly carefully about the location for his project. ‘First, I was thinking I could take images in the Democratic Republic of the Congo,’ he says. ‘But then I thought that if you chose a place that has war, it’s logical that electricity won’t really work. So, instead, I wanted to find a place that is quite stable. I decided to go to Benin, where they have a democracy. It is a good example of a country that’s not in really bad shape but where they still have this problem. Also, I didn’t want to go to a place that is very remote, where it is normal not to have good service. So I decided to go to a place around 50 kilometres from the capital that you can get to by road.’

Maitre visited several villages in the region, as well as making trips to Chad and Senegal, and encountered the full range of limitations engendered by the power shortage. From teachers struggling to conduct lessons in the dark to midwives forced to work with only the weak light from a phone, the situation was clearly unacceptable. ‘People were very, very, very upset,’ he says. ‘I conducted a lot of interviews in different villages and lack of electricity touches education, economy, business, security and also emigration, because people have to move to big cities or maybe to Europe to get jobs.’

Where once the situation might have been accepted as the norm, people today are fully aware of the ways in which they are held back by the lack of power. As Maitre remembers: ‘A guy said to me one day, “Do you think it is normal that last time my wife delivered a baby, the midwife had to hold her phone between her teeth in order to see what she was doing?” You feel very frustrated.’ He adds that the fact that most people now have mobile phones only highlights the hardship. ‘Before, maybe it was not so frustrating. But now, most of these people have cellphones. The cellphone company puts antennae everywhere so the phones work, but people cannot recharge their phones. They have to go to the market, where someone will come with a generator to recharge.’

Governments and global organisations are very aware of the problem across the world as a whole. Sustainable Development Goal 7 (SDG7) – one of the 17 goals set out in 2015 by the United Nations General Assembly – was designed to ensure universal access to affordable, reliable, sustainable and modern energy by 2030, underscoring the push for clean, affordable and sustainable electricity for all by 2030. As part of this goal, international financial flows to developing countries in support of clean energy reached US$17 billion in 2018. As a result, some areas have seen huge improvement. According to the Energy Progress Report, in Latin America and the Caribbean, and in Eastern and South-Eastern Asia, the advance of electrification has been enough to approach universal access. By 2019, in Western Asia and North Africa, and Central and South Asia, 94 and 95 per cent of the population respectively had access to electricity.

But these statistics only serve to emphasise just how bad the situation is in sub-Saharan Africa, where electricity systems are unlikely to go green this decade according to several analyses. As the report states: ‘While renewable energy has demonstrated remarkable resilience during the pandemic, the unfortunate fact is that gains in energy access throughout Africa are being reversed: the number of people lacking access to electricity is set to increase in 2020, making basic electricity services unaffordable for up to 30 million people who had previously enjoyed access.’

The small silver lining is that if the situation is dealt with properly, the region could build a renewable-energy system from the ground up, rather than having to undergo the costly and complex transitions underway in developed countries. In rural areas, small-scale or off-grid renewable systems (mostly solar) are expected to play an important role, as highlighted by a recent IRENA report on decarbonisation, in increasing access. In fact, solar panels are already used in many areas. In 2019, 105 million people had access to off-grid solar solutions, up from 85 million in 2016, and almost half lived in sub-Saharan Africa, with 17 million in Kenya and eight million in Ethiopia.

Rachel Kyte is currently serving as the 14th dean of the Fletcher School at Tufts University in the USA, but her CV is long. She was previously CEO of the UN-affiliated Sustainable Energy for All (SeforALL), as well as the World Bank Group vice president and special envoy for climate change, leading the run-up to the Paris Agreement. According to her, a focus on renewables is absolutely essential, both for wider efforts to tackle climate change, with some advocating a fossil fuel lockdown to drive a climate revolution, but also for the people of sub-Saharan Africa. ‘The fossil fuel industry has said it will just extend the centralised fossil-fuel power systems that we have today to reach these people,’ she says.

Ontario Natural Gas Moratorium gains momentum as IESO weighs energy storage, renewables, and demand management to meet rising electricity demand, ensure grid reliability, and advance zero-emissions goals while long-term capacity procurements proceed.

Key Points

A proposed halt on new gas plants as IESO assesses storage and renewables to maintain reliability and cut emissions.

✅ Minister seeks interim IESO report by Oct. 7

✅ Near-term contracts extend existing gas plants for reliability

✅ Long-term procurements emphasize storage, renewables, conservation

Ontario's energy minister says he doesn't think the province needs any more natural gas generation and has asked the electricity system regulator to speed up a report exploring a moratorium.

Todd Smith had previously asked the Independent Electricity System Operator (IESO) to report back by November on the feasibility of a moratorium and a plan to get to zero emissions in the electricity sector.

He has asked them today for an interim report by Oct. 7 so he can make a decision on a moratorium before the IESO secures contracts over the long term for new power generation.

"I've asked the IESO to speed up that report back to us so that we can get the information from them as to what the results would be for our grid here in Ontario and whether or not we actually need more natural gas," Smith said Tuesday after question period.

"I don't believe that we do."

Smith said that is because of the "huge success" of two updates provided Tuesday by the IESO to its attempts to secure more electricity supply for both the near term and long term. Demand is growing by nearly two per cent a year, while Ontario is set to lose a significant amount of nuclear generation, including the planned shutdown of the Pickering nuclear station over the next few years.

'For the near term, we need them,' regulator says
The regulator today released a list of 55 qualified proponents for those long-term bids and while it says there is a significant amount of proposed energy storage projects on that list, there are some new gas plants on it as well.

Chuck Farmer, the vice-president of planning, conservation and resource adequacy at the IESO, said it's hoped that the minister makes a decision on whether or not to issue a moratorium on new gas generation before the regulator proceeds with a request for proposals for long-term contracts.

The IESO also announced six new contracts — largely natural gas, with a small amount of wind power and storage — to start in the next few years. Farmer noted that these contracts were specifically for existing generators whose contracts were ending, while the province is exploring new nuclear plants for the longer term.

"When you look at the pool of generation resources that were in that situation, the reality is most of them were actually natural gas plants, and that we are relying on the continued use of the natural gas plants in the transition," he said in an interview. 

"So for the near term, we need them for the reliability of the system."

The upcoming request for proposals for more long-term contracts hopes to secure 3,500 megawatts of capacity, as Ontario faces an electricity shortfall in the coming years, and Farmer said the IESO plans to run a series of procurements over the next few years.

Opposition slams reliance on natural gas
The NDP and Greens on Tuesday criticized Ontario's reliance in the near term on natural gas because of its environmental implications.

The IESO has said that due to natural gas, greenhouse gas emissions from the electricity sector are set to increase for the next two decades, but by about 2038 it projects the net reductions from electric vehicles will offset electricity sector emissions.

Green Party Leader Mike Schreiner said it makes no sense to ramp up natural gas, both for the climate and for people's wallets.

"The cost of wind and solar power is much lower than gas," he said.

Ontario quietly revises its plan for hitting climate change targets
"We're in a now-or-never moment to address the climate crisis and the government is failing to meet this moment."

Interim NDP Leader Peter Tabuns said Ontario wouldn't be in as much of a supply crunch if the Progressive Conservative government hadn't cancelled 750 green energy contracts during their first term.

The Tories argued the province didn't need the power and the contracts were driving up costs for ratepayers, amid debate over whether greening the grid would be affordable.

The IESO said it is also proposing expanding conservation and demand management programs, as a "highly cost-effective" way to reduce strain on the system, though it couldn't say exactly what is on the table until the minister accepts the recommendation.

US-Canada Electricity Tariff Dispute intensifies as proposed tariffs spur Canadian threats to restrict hydroelectric exports, risking cross-border energy supply, grid reliability, higher electricity prices, and clean energy goals in the Northeast and Midwest.

Key Points

Trade clash over tariffs and hydroelectric exports that threatens power supply, prices, and grid reliability.

✅ Potential export curbs on Canadian hydro to US markets

✅ Risks: higher prices, strained grids, reduced clean energy

✅ Diplomacy urged to avoid retaliatory trade measures

In early February 2025, escalating trade tensions between the United States and Canada have raised concerns about the future of electricity exports from Canada to the U.S. The potential imposition of tariffs by the U.S. has prompted Canadian officials to consider retaliatory measures, including restricting electricity exports and pursuing high-level talks such as Ford's Washington meeting with federal counterparts.

Background of the Trade Dispute

In late November 2024, President-elect Donald Trump announced plans to impose a 25% tariff on all Canadian products, citing issues related to illegal immigration and drug trafficking. This proposal has been met with strong opposition from Canadian leaders, who view such tariffs as unjustified and detrimental to both economies, even as tariff threats boost support for Canadian energy projects among some stakeholders.

Canada's Response and Potential Retaliatory Measures

In response to the proposed tariffs, Canadian officials have discussed various countermeasures. Ontario Premier Doug Ford has threatened to cut electricity supplies to 1.5 million Americans and ban imports of U.S.-made beer and liquor. Other provinces, such as Quebec and Alberta, are also considering similar actions, though experts advise against cutting Quebec's energy exports due to reliability concerns.

Impact on U.S. Energy Supply

Canada is a significant supplier of electricity to the United States, particularly in regions like the Northeast and Midwest. A reduction or cessation of these exports could lead to energy shortages and increased electricity prices in affected U.S. states, with New York especially vulnerable according to regional assessments. For instance, Ontario exports substantial amounts of electricity to neighboring U.S. states, and any disruption could strain local energy grids.

Economic Implications

The imposition of tariffs and subsequent retaliatory measures could have far-reaching economic consequences. In Canada, industries such as agriculture, manufacturing, and energy could face significant challenges due to reduced access to the U.S. market, even as many Canadians support energy and mineral tariffs as leverage. Conversely, U.S. consumers might experience higher prices for goods and services that rely on Canadian imports, including energy products.

Environmental Considerations

Beyond economic factors, the trade dispute could impact environmental initiatives. Canada's hydroelectric power exports are a clean energy source that helps reduce carbon emissions in the U.S., where policymakers look to Canada for green power to meet targets. A reduction in these exports could lead to increased reliance on fossil fuels, potentially hindering environmental goals.

The escalating trade tensions between the United States and Canada, particularly concerning electricity exports, underscore the complex interdependence of the two nations. While the situation remains fluid, it highlights the need for diplomatic engagement to resolve disputes and maintain the stability of cross-border energy trade.

Hinkley Point C Reactor Installation signals UK energy security, nuclear power expansion, and low-carbon baseload, featuring EPR technology in Somerset to cut emissions, support net-zero goals, and deliver reliable electricity for homes and businesses.

Key Points

First EPR unit fitted at Hinkley Point C, boosting low-carbon baseload, grid reliability, and UK energy security.

✅ Generates 3.2 GW across two EPRs for 7% of UK electricity.

✅ Provides low-carbon baseload to complement wind and solar.

✅ Creates jobs and strengthens supply chains during construction.

The United Kingdom has made a significant stride toward securing its energy future with the installation of the first reactor at its newest nuclear power station. This development marks an important milestone in the nation’s efforts to combat climate change, reduce carbon emissions, and ensure a stable and sustainable energy supply. As the world moves towards greener alternatives to fossil fuels, nuclear power remains a key part of the UK's green industrial revolution and low-carbon energy strategy.

The new power station, located at Hinkley Point C in Somerset, is set to be one of the most advanced nuclear facilities in the country. The installation of its reactor represents a crucial step in the construction of the plant, with earlier milestones like the reactor roof lifted into place underscoring steady progress, which is expected to provide reliable, low-carbon electricity for millions of homes and businesses across the UK. The completion of the first reactor is seen as a pivotal moment in the journey to bring the station online, with the second reactor expected to follow shortly after.

A Historic Milestone

Hinkley Point C will be the UK’s first nuclear power station built in over two decades. The plant, once fully operational, will play a key role in the country's energy transition. The reactors at Hinkley Point C are designed to be state-of-the-art, using advanced technology that is both safer and more efficient than older nuclear reactors. Each of the two reactors will have the capacity to generate 1.6 gigawatts of electricity, enough to power approximately six million homes. Together, they will contribute about 7% of the UK’s electricity needs, providing a steady, reliable source of energy even during periods of high demand.

The installation of the first reactor at Hinkley Point C is not just a technical achievement; it is also symbolic of the UK’s commitment to energy security and its goal to achieve net-zero carbon emissions by 2050, a target that industry leaders say multiple new stations will be needed to meet effectively. Nuclear power is a crucial part of this equation, as it provides a stable, baseload source of energy that does not rely on weather conditions, unlike wind or solar power.

Boosting the UK’s Energy Capacity

The addition of Hinkley Point C to the UK’s energy infrastructure is expected to significantly boost the country’s energy capacity and reduce its reliance on fossil fuels. The UK government has been focused on increasing the share of renewable energy in its mix, and nuclear power is seen as an essential complement to intermittent renewable sources, especially as wind and solar have surpassed nuclear in generation at times. Nuclear energy is considered a low-carbon, reliable energy source that can fill the gaps when renewable generation is insufficient, such as on cloudy or calm days when solar and wind energy output may be low.

With the aging of the UK’s existing nuclear fleet and the gradual phase-out of coal-fired power plants, Hinkley Point C will help ensure that the country does not face an energy shortage as it transitions to cleaner energy sources. The plant will help to bridge the gap between the current energy infrastructure and the future, enabling the UK to phase out coal while maintaining a steady, low-carbon energy supply.

Safety and Technological Innovation

The reactors at Hinkley Point C are being constructed using the latest in nuclear technology. They are based on the European Pressurized Reactor (EPR) design, which is known for its enhanced safety features and efficiency, and has been deployed in projects within China's nuclear program as well, making it a proven platform. These reactors are designed to withstand extreme conditions, including earthquakes and flooding, making them highly resilient. Additionally, the EPR technology ensures that the reactors have a low environmental impact, producing minimal waste and offering the potential for increased sustainability compared to older reactor designs.

One of the key innovations in the Hinkley Point C reactors is their advanced cooling system, which is designed to be more efficient and environmentally friendly than previous generations. This system ensures that the reactors operate at optimal temperatures while minimizing the environmental footprint of the plant.

Economic and Job Creation Benefits

The construction of Hinkley Point C has already provided a significant boost to the local economy. Thousands of jobs have been created, not only in the construction phase but also in the ongoing operation and maintenance of the facility. The plant is expected to create more than 25,000 jobs during its construction and around 900 permanent jobs once it is operational.

The project is also expected to have a positive impact on the wider UK economy. As a major infrastructure project, Hinkley Point C will provide long-term economic benefits, including boosting supply chains and providing opportunities for local businesses.

Challenges and the Road Ahead

Despite the progress, the construction of Hinkley Point C has not been without its challenges. The project has faced delays and cost overruns, with setbacks at Hinkley Point C documented by industry observers, and the total estimated cost now standing at around £22 billion. However, the successful installation of the first reactor is a step toward overcoming these hurdles and completing the project on schedule.

Looking ahead, Hinkley Point C’s successful operation could pave the way for future nuclear developments in the UK, including next-gen nuclear designs that aim to be smaller, cheaper, and safer. As the world grapples with the pressing need to reduce greenhouse gas emissions, nuclear energy may play an even more critical role in ensuring a clean, reliable energy future.

The installation of the first reactor at Hinkley Point C marks a crucial moment in the UK’s energy journey. As the country seeks to meet its carbon reduction targets and bolster its energy security, the new nuclear power station will be a cornerstone of its efforts. With its advanced technology, safety features, and potential to provide low-carbon energy for decades to come, Hinkley Point C offers a glimpse into the future of energy production in the UK and beyond.
