Atomic Energy of Canada Limited (AECL) provides the following status report on the unplanned shutdown of the NRU reactor at its Chalk River Laboratories.

AECL reports that removal of the last NRU fuel rod was successfully completed June 15. Removal of the remaining 15 control, adjuster and cobalt-60 isotope rods has begun. Seven of these assemblies were removed from the reactor as of June 16.

Completion of rod removal and the subsequent removal of heavy water from the reactor is expected to be complete by the end of this month. Final preparations are underway to conduct a detailed inspection of the condition of the reactor vessel using remote non-destructive examination techniques. This task will be performed as soon as the remaining rods and heavy water have been removed.

AECL is drawing on advice provided by its technical staff and industry experts to determine the most effective options for vessel repairs. AECL continues to work with industry experts on cleaning, inspection and repair techniques for the reactor vessel. Earlier this week, AECL was provided with a demonstration of a potential repair technique from a supplier company. Evaluation of this and other inspection, cleaning and repair options continues.

A full-scale mock-up of a portion of the NRU vessel is currently being constructed at Chalk River. This mock-up will serve to provide on-site testing and training of vessel inspection and repair work.

The NRU heavy water leak rate has been reduced to a flow of between 3-4 kg/hr. A small portion of the leakage evaporates and results in a monitored airborne tritium release through the NRU reactor ventilation system. While this airborne tritium release remains about 1/1,000 of the regulatory limit, the action level for tritium release to the atmosphere was exceeded this week due to the leak.

AECL confirms that there is no threat to workers, the public, the environment or nuclear safety related to this event. AECL will continue to provide updates to the CNSC and stakeholders when new information becomes available.

Canadian Solar and Tesla contribute to resilient electricity system for Puerto Rico school

SunCrate Solar Microgrid delivers resilient, plug-and-play renewable power to Puerto Rico schools, combining Canadian Solar PV, Tesla Powerwall battery storage, and Black & Veatch engineering to ensure off-grid continuity during outages and disasters.

 

Key Points

A compact PV-and-battery system for resilient, diesel-free power and microgrid backup at schools and clinics.

✅ Plug-and-play, modular PV, inverter, and battery architecture

✅ Tesla Powerwall storage; Canadian Solar 325 W panels

✅ Scales via daisy-chain for higher loads and microgrids

 

Eleven months since their three-building school was first plunged into darkness by Hurricane Maria, 140 students in Puerto Rico’s picturesque Yabucoa district have reliable power. Resilient electricity service was provided Saturday to the SU Manuel Ortiz school through an innovative scalable, plug-and-play solar system pioneered by SunCrate Energy with Black & Veatch support. Known as a “SunCrate,” the unit is an effective mitigation measure to back up the traditional power supply from the grid. The SunCrate can also provide sustainable power in the face of ongoing system outages and future natural disasters without requiring diesel fuel.

The humanitarian effort to return sustainable electricity to the K-8 school, found along the island’s hard-hit southeastern coast, drew donated equipment and expertise from a collection of North American companies. Additional support for the Yabucoa project came from Tesla, Canadian Solar and Lloyd Electric, reflecting broader efforts to build a solar-powered grid in Puerto Rico after Hurricane Maria.

“We are grateful for this initiative, which will equip this school with the technology needed to become a resilient campus and not dependent on the status of the power grid. This means that if we are hit with future harmful weather events, the school will be able to open more quickly and continue providing services to students,” Puerto Rico Secretary of Education Julia Keleher said.

The SunCrate harnesses a scalable rapid-response design developed by Black & Veatch and manufactured by SunCrate Energy. Electricity will be generated by an array of 325-W CS6U-Poly modules from Canadian Solar. California-based Tesla contributed advanced battery energy storage through various Powerwall units capable of storing excess solar power and delivering it outside peak generation periods, with related experience from a virtual power plant in Texas informing deployment.  Lloyd Electric Co. of Wichita Falls, Texas, partnered to support delivery and installation of the SunCrate.

“As families in the region begin to prepare for the school year, this community is still impacted by the longest U.S. power outage in history,” said Dolf Ivener, a Midwestern entrepreneur who owns King of Trails Construction and SunCrate Energy, which is donating the SunCrate. “SunCrate, with its rapid deployment and use of renewable energy, should give this school peace of mind and hopefully returns a touch of long-overdue normalcy to students and their parents. When it comes to consistent power, SunCrate is on duty.”

The SunCrate is a portable renewable energy system conceived by Ivener and designed and tested by Black & Veatch. Its modular design uses solar PV panels, inverters and batteries to store and provide electric power in support of critical services such as police, fire, schools, clinics and other community level facilities.

A SunCrate can generate 23 to 156 kWh per day, and store 10 kWh to 135 kWh depending on configuration. A SunCrate’s power generation and storage capacity can be easily scaled through daisy-chained configurations to accommodate larger buildings and loads. Leveraging resources from Tesla, Canadian Solar, Lloyd Electric and Lord Electric, the unit in Yabucoa will provide an estimated 52 kWh of storable power without requiring use of costlier diesel-powered generators and cutting greenhouse gas emissions. Its capabilities allow the school to strengthen its function as a designated Community Emergency Response Center in the event of future natural disasters.

“Canadian Solar has a long history of using solar power to support humanitarian efforts aiding victims of social injustice and natural disasters, including previous donations to Puerto Rico after Hurricane Maria,” said Dr. Shawn Qu, Chairman and Chief Executive Officer of Canadian Solar. “We are pleased to make the difference for these schoolchildren in Yabucoa who have been without reliable power for too long.”

The SunCrate will also substantially lower the school’s ongoing electricity costs by providing a reliable source of renewable energy on site, as falling costs of solar batteries improve project economics overall.

“Through our experience providing engineering services in Puerto Rico for nearly 50 years, including dozens of specialized projects for local government and industrial clients, we see great potential for SunCrate as a source of resilient power for the Commonwealth’s remote schools and communities at large, underscoring the importance of electricity resilience across critical infrastructure,” said Charles Moseley, a Program Director in Black & Veatch’s water business. “We hope that the deployment of the SunCrate in Yabucoa sets a precedent for facility and municipal level migro-grid efforts on the island and beyond.”

SunCrate also has broad potential applications in conflict/post-conflict environments and in rural electrification efforts in the developing world, serving as a resilient source of electricity within hours of its arrival on site and could enable peer-to-peer energy within communities. Of particular benefit, the system’s flexibility cuts fuel costs to a fraction of a generator’s typical consumption when they are used around the clock with maintenance requirements.

Africa's Electricity Unlikely To Go Green This Decade

Africa 2030 Energy Mix Forecast finds electricity generation doubling, with fossil fuels dominant, non-hydro renewables under 10%, hydro vulnerable to droughts, and machine-learning analysis of planned power plants shaping climate and investment decisions.

 

Key Points

An analysis predicting Africa's 2030 power mix, with fossil fuels dominant, limited renewables growth, and hydro risks.

✅ ML model assesses 2,500 planned plants' commissioning odds

✅ Fossil fuels ~66% of generation; non-hydro RE <10% by 2030

✅ Policy shifts and finance reallocation to scale solar and wind

 

New research today from the University of Oxford predicts that total electricity generation across the African continent will double by 2030, with fossil fuels continuing to dominate the energy mix posing potential risk to global climate change commitments.

The study, published in Nature Energy, uses a state-of-the art machine-learning technique to analyse the pipeline of more than 2,500 currently-planned power plants and their chances of being successfully commissioned. It shows the share of non-hydro renewables in African electricity generation is likely to remain below 10% in 2030, although this varies by region.

'Africa's electricity demand is set to increase significantly as the continent strives to industrialise and improve the wellbeing of its people, which offers an opportunity to power this economic development and expand universal electricity access through renewables' says Galina Alova, study lead author and researcher at the Oxford Smith School of Enterprise and the Environment.

'There is a prominent narrative in the energy planning community that the continent will be able to take advantage of its vast renewable energy resources and rapidly decreasing clean technology prices to leapfrog to renewables by 2030 but our analysis shows that overall it is not currently positioned to do so.'

The study predicts that in 2030, fossil fuels will account for two-thirds of all generated electricity across Africa. While an additional 18% of generation is set to come from hydro-energy projects across Africa. These have their own challenges, such as being vulnerable to an increasing number of droughts caused by climate change.

The research also highlights regional differences in the pace of the transition to renewables across Sub-Saharan Africa, with southern Africa leading the way. South Africa alone is forecast to add almost 40% of Africa's total predicted new solar capacity by 2030.

'Namibia is committed to generate 70% of its electricity needs from renewable sources, including all the major alternative sources such as hydropower, wind and solar generation, by 2030, as specified in the National Energy Policy and in Intended Nationally Determined Contributions under Paris Climate Change Accord,' says Calle Schlettwein, Namibia Minister of Water (former Minister of Finance and Minister of Industrialisation). 'We welcome this study and believe that it will support the refinement of strategies for increasing generation capacity from renewable sources in Africa and facilitate both successful and more effective public and private sector investments in the renewable energy sector.'

Minister Schlettwein adds: 'The more data-driven and advanced analytics-based research is available for understanding the risks associated with power generation projects, the better. Some of the risks that could be useful to explore in the future are the uncertainties in hydrological conditions and wind regimes linked to climate change, and economic downturns such as that caused by the COVID-19 pandemic.'

The study further suggests that a decisive move towards renewable energy in Africa would require a significant shock to the current system. This includes large-scale cancellation of fossil fuel plants currently being planned. In addition, the study identifies ways in which planned renewable energy projects can be designed to improve their success chances for example, smaller size, fitting ownership structure, and availability of development finance for projects.

'The development community and African decision makers need to act quickly if the continent wants to avoid being locked into a carbon-intense energy future' says Philipp Trotter, study author and researcher at the Smith School. 'Immediate re-directions of development finance from fossil fuels to renewables are an important lever to increase experience with solar and wind energy projects across the continent in the short term, creating critical learning curve effects.'

Wind and solar make more electricity than nuclear for first time in UK

UK Renewables Surpass Nuclear Milestone as wind farms and solar panels outpace atomic output, cutting greenhouse gas emissions. BEIS data show low-carbon power generation rising while onshore wind subsidies and auction timelines face policy debate.

 

Key Points

It is the quarter when UK wind and solar generated more electricity than nuclear, signaling cleaner, low-carbon growth.

✅ BEIS reports wind and solar at 18.33 TWh vs nuclear 16.69 TWh

✅ Energy sector emissions fell 8% as coal use dropped

✅ Calls grow to reopen onshore wind support via CFD auctions

 

Wind farms and solar panels, with wind leading the power mix during key periods, produced more electricity than the UK’s eight nuclear power stations for the first time at the end of last year, official figures show.

Britain’s greenhouse gas emissions also continued to fall, dropping 3% in 2017, as coal use fell and the use of renewables climbed, though low-carbon generation stalled in 2019 according to later data.

Energy experienced the biggest drop in emissions of any UK sector, of 8%, while pollution from transport and businesses stayed flat.

Energy industry chiefs said the figures showed that the government should rethink its ban on onshore wind subsidies, a move that ministers have hinted could happen soon.

Lawrence Slade, chief executive of the big six lobby group Energy UK, said: “We need to keep up the pace ... by ensuring that the lowest cost renewables are no longer excluded from the market.”

Across the whole year, low-carbon sources of power – wind, solar, biomass and nuclear – provided a record 50.4% of electricity, up from 45.7% in 2016, when wind beat coal for the first time.

But in the fourth quarter of 2017, high wind speeds, new renewables installations and lower nuclear output saw wind and solar becoming the second biggest source of power for the first time.

Wind and solar generated 18.33 terawatt hours (TWh), with nuclear on 16.69TWh, and the UK later set a new record for wind power during 2019, the figures published by the Department for Business, Energy and Industrial Strategy show.

But renewables still have a long way to go to catch up with gas, the UK’s top source of electricity at 36.12TWh, which saw its share of generation fall slightly, though at times wind became the main source as capacity expanded.

Greenpeace said the figures showed the government should capitalise on its lead in renewables and “stop wasting time and money propping up nuclear power”.

Horizon Nuclear Power, a subsidiary of the Japanese conglomerate Hitachi, is in talks with Whitehall officials for a financial support package from the government, which it says it needs by midsummer.

By contrast, large-scale solar and onshore wind projects are not eligible for support, after the Conservative government cut subsidies in 2015.

However the energy minister, Claire Perry, recently told House Magazine that “we will have another auction that brings forward wind and solar, we just haven’t yet said when”.

Wind and Solar Double Global Share of Electricity in Five Years

Wind And Solar Energy Growth is reshaping the global power mix, accelerating grid decarbonization as coal declines; boosted by pandemic demand drops, renewables now supply near 10% of electricity, advancing climate targets toward net-zero trajectories.

 

Key Points

It is the rise in wind and solar's share of electricity, driving decarbonization and displacing coal globally.

✅ Share doubled in five years across 83% of global electricity

✅ Coal's share fell; renewables neared 10% in H1 2020

✅ Growth still insufficient for 1.5 C; needs ~13% coal cuts yearly

 

Wind and solar energy doubled its share of the global power mix over the last five years, with renewable power records underscoring the trend, moving the world closer to a path that would limit the worst effects of global warming.

The sources of renewable energy made up nearly 10% of power in most parts of the world in the first half of this year, according to analysis from U.K. environmental group Ember, while globally over 30% of electricity is renewable in broader assessments.

That decarbonization of the power grid was boosted this year as shutdowns to contain the coronavirus reduced demand overall, leaving renewables to pick up the slack.

Ember analyzed generation in 48 countries that represent 83% of global electricity. The data showed wind and solar power increased 14% in the first half of 2020 compared with the same period last year while global demand fell 3% because of the impact of the coronavirus.

At the same time that wind turbines and solar panels have proliferated, coal’s share of the mix has fallen around the world. In some, mainly western European countries, where renewables surpassed fossil fuels, coal has been all but eliminated from electricity generation.


China relied on the dirtiest fossil fuel for 68% of its power five years ago, and solar PV growth in China has accelerated since then. That share dipped to 62% this year and renewables made up 10% of all electricity generated.

Still, the growth of renewables may not be going fast enough for the world to hit its climate goals, even as the U.S. is projected to have one-fourth of electricity from renewables soon, and coal is still being burnt for power in many parts of the world.

Coal use needs to fall by about 79% by 2030 from last year’s levels - a fall of 13% every year throughout the decade to come, and in the U.S. renewable electricity surpassed coal in 2022, Ember said.

New installations of wind farms are set to hold more or less steady in the next five years, according to data from BloombergNEF on deployment trends. That will make it difficult to realize a sustained pace of doubling renewable power every five years.

“If your expectations are that we need to be on target for 1.5 degrees, clearly we’re not going fast enough,” said Dave Jones, an analyst at Ember. “We’re not on a trajectory where we’re reducing coal emissions fast enough.”

Snohomish PUD Hikes Rates Due to Severe Weather Impact

Snohomish PUD rate increase addresses storm recovery after a bomb cyclone and extended cold snap, stabilizing finances and grid reliability while offering assistance programs, payment plans, and energy efficiency for customers.

 

Key Points

Temp 5.8% residential hike in Feb 2025 to recover storm costs, meet cold snap demand, and uphold reliable service.

✅ 5.8% residential increase effective Feb 2025

✅ Driven by bomb cyclone damage and cold snap demand

✅ Aid includes payment plans, efficiency rebates, low income support

 

In early February 2025, the Snohomish County Public Utility District (PUD) announced a temporary increase in electricity rates to offset the financial impact of severe weather events, including a bomb cyclone and an extended cold snap, that occurred in late 2024. This decision aims to stabilize the utility's finances, a pattern seen at other utilities such as Florida Power & Light, which pursued a hurricane surcharge to recover storm costs, while ensuring continued service reliability for its customers.

Background of the Weather Events

In November 2024, the Pacific Northwest experienced a powerful bomb cyclone—a rapidly intensifying storm characterized by a significant drop in atmospheric pressure. This event brought heavy rainfall, strong winds, and widespread power outages across the region. Compounding the situation, a prolonged cold weather period in December 2024 and January 2025 led to increased energy demand, and similar conditions drove up Pennsylvania power rates in the same winter season, as residents and businesses relied heavily on heating systems.

Impact on Snohomish PUD

The combination of the bomb cyclone and the subsequent cold weather placed considerable strain on the Snohomish PUD's infrastructure and financial resources. The utility incurred substantial costs for emergency repairs, restoration efforts, and the procurement of additional electricity to meet the heightened demand during the cold snap. These unforeseen expenses prompted the PUD to seek a temporary rate adjustment to maintain financial stability and continue providing reliable service to its customers.

Details of the Rate Increase

Effective February 2025, the Snohomish PUD implemented a temporary electricity rate increase of 5.8% for residential customers, compared with a 3% BC Hydro increase in the same region for context. This adjustment is designed to recover the additional costs incurred during the severe weather events. The PUD has communicated that this rate increase is temporary and will be reevaluated after a specified period to determine if further adjustments are necessary.

Customer Impact and Assistance Programs

While the rate increase is intended to be temporary, it may still pose a financial burden for some customers, even as some markets expect rates to stabilize in 2025 in other jurisdictions. To mitigate this impact, the Snohomish PUD has outlined several assistance programs:

  • Payment Plans: Customers facing financial hardship can enroll in extended payment plans to spread the cost of the increased rates over a longer period.

  • Energy Efficiency Programs: The PUD offers incentives and resources to help customers reduce energy consumption, potentially lowering their overall bills.

  • Low-Income Assistance: Eligible low-income customers may qualify for additional support through state and federal assistance programs.

The utility encourages customers to contact their customer service department to explore these options and find the best solutions for their individual circumstances.

Community Response and Future Considerations

The announcement of the rate increase has elicited mixed reactions from the community. Some residents express understanding, recognizing the necessity of maintaining infrastructure and service reliability. Others have voiced concerns about the financial impact, particularly among vulnerable populations, a debate also seen with higher BC Hydro rates in nearby British Columbia.

Looking ahead, the Snohomish PUD is committed to enhancing its infrastructure to better withstand future extreme weather events, an approach aligned with other utilities' multi-year rate proposals to fund upgrades. This includes investing in grid modernization, implementing advanced weather forecasting tools, and developing comprehensive emergency response plans. The utility also plans to engage with the community through public forums and surveys to gather feedback and collaboratively develop strategies that balance financial sustainability with customer affordability.

The temporary electricity rate increase by the Snohomish County Public Utility District reflects the financial challenges posed by severe weather events and parallels regional trends, including BC Hydro's 3.75% over two years adjustments, and underscores the importance of proactive infrastructure investment and community engagement. While the rate adjustment aims to stabilize the utility's finances, the PUD remains focused on supporting its customers through assistance programs and ongoing efforts to enhance service reliability and resilience against future climate-related events.
