Grid confronts a threat from Mother Nature

Vogtle Unit 3 Initial Criticality marks the startup of a new U.S. nuclear reactor, initiating fission to produce heat, steam, and electricity, supporting clean energy goals, grid reliability, and carbon-free baseload power.

Key Points

Vogtle Unit 3 Initial Criticality is the first fission startup, launching power generation at a new U.S. reactor.

✅ First new U.S. reactor to reach criticality since 2016

✅ Generates carbon-free baseload power for the grid

✅ Faced cost overruns and delays during construction

For the first time in almost seven years, a new nuclear reactor has started up in the United States.

On Monday, Georgia Power announced that the Vogtle nuclear reactor Unit 3 has started a nuclear reaction inside the reactor as part of the first new reactors in decades now taking shape at the plant.

Technically, this is called “initial criticality.” It’s when the nuclear fission process starts splitting atoms and generating heat, Georgia Power said in a written announcement.

The heat generated in the nuclear reactor causes water to boil. The resulting steam spins a turbine that’s connected to a generator that creates electricity.

Vogtle’s Unit 3 reactor will be fully in service in May or June, Georgia Power said.

The last time a nuclear reactor reached the same milestone was almost seven years ago in May 2016 when the Tennessee Valley Authority started splitting atoms at the Watts Bar Unit 2 reactor in Tennessee, Scott Burnell, a spokesperson for the Nuclear Regulatory Commission, told CNBC.

“This is a truly exciting time as we prepare to bring online a new nuclear unit that will serve our state with clean and emission-free energy for the next 60 to 80 years,” Chris Womack, CEO of Georgia Power, said in a written statement. 

Including the newly turned-on Vogtle Unit 3 reactor, there are currently 93 nuclear reactors operating in the United States and, collectively, they generate 20% of the electricity in the country, although a South Carolina plant leak recently showed how outages can sideline a unit for weeks.

Nuclear reactors, which help combat global warming and support net-zero emissions goals, generate about half of the clean, carbon-free electricity generated in the U.S.

Most of the nuclear power reactors in the United States were constructed between 1970 and 1990, but construction slowed significantly after the accident at Three Mile Island near Middletown, Pennsylvania, on March 28, 1979, even as interest in next-gen nuclear power has grown in recent years. From 1979 through 1988, 67 nuclear reactor construction projects were canceled, according to the U.S. Energy Information Administration.

However, because nuclear energy is generated without releasing carbon dioxide emissions, which cause global warming, the increased sense of urgency in responding to climate change has given nuclear energy a chance at a renaissance as atomic energy heats up again globally.

The cost associated with building nuclear reactors is a major barrier to a potential resurgence in nuclear energy, however, even as nuclear generation costs have fallen to a ten-year low. And the new builds at Vogtle have become an epitome of that charge: The construction of the two Vogtle reactors has been plagued by cost overruns and delays.

BC Autonomous Vehicle Ban freezes new driverless testing and deployment as BC develops a regulatory framework, prioritizing safety, liability clarity, and road sharing with pedestrians and cyclists while existing pilot projects continue.

Key Points

A moratorium pausing new driverless testing until a safety-first regulatory framework and clear liability rules exist.

✅ Freezes new AV testing and deployment provincewide

✅ Current pilot shuttles continue under existing approvals

✅ Focus on safety, liability, and road-user integration

British Columbia has halted the expansion of fully autonomous vehicles on its roads. The province has announced it will not approve any new applications for testing or deployment of vehicles that operate without a human driver until it develops a new regulatory framework, even as it expands EV charging across the province.

Safety Concerns and Public Questions

The decision follows concerns about the safety of self-driving vehicles and questions about who would be liable in the event of an accident. The BC government emphasizes the need for robust regulations to ensure that self-driving cars and trucks can safely share the road with traditional vehicles, pedestrians, and cyclists, and to plan for infrastructure and power supply challenges associated with electrified fleets.

"We want to make sure that British Columbians are safe on our roads, and that means putting the proper safety guidelines in place," said Rob Fleming, Minister of Transportation and Infrastructure. "As technology evolves, we're committed to developing a comprehensive framework to address the issues surrounding self-driving technology."

What Does the Ban Mean?

The ban does not affect current pilot projects involving self-driving vehicles that already operate in BC, such as limited shuttle services and segments of the province's Electric Highway that support charging and operations.

Industry Reaction

The response from industry players working on autonomous vehicle technology has been mixed, amid warnings of a potential EV demand bottleneck as adoption ramps up. While some acknowledge the need for clear regulations, others express concern that the ban could stifle innovation in the province.

"We understand the government's desire to ensure safety, but a blanket ban risks putting British Columbia behind in the development of this important technology," says a spokesperson for a self-driving vehicle start-up.

Debate Over Self-Driving Technology

The BC ban highlights a larger debate about the future of autonomous vehicles. While proponents point to potential benefits such as improved safety, reduced traffic congestion, and increased accessibility, and national policies like Canada's EV goals aim to accelerate adoption, critics raise concerns about liability, potential job losses in the transportation sector, and the ability of self-driving technology to handle complex driving situations.

BC Not Alone

British Columbia is not the only jurisdiction grappling with the regulation of self-driving vehicles. Several other provinces and states in both Canada and the U.S. are also working to develop clear legal and regulatory frameworks for this rapidly evolving technology, even as studies suggest B.C. may need to double its power output to fully electrify road transport.

The Road Ahead

The path forward for fully autonomous vehicles in BC depends on the government's ability to create a regulatory framework that balances safety considerations with fostering innovation, and align with clean-fuel investments like the province's hydrogen project to support zero-emission mobility.  When and how that framework will materialize remains unclear, leaving the future of self-driving cars in the province temporarily uncertain.

Texas power grid highlights ERCOT reliability strains from extreme heat, climate change, and low wind, as natural gas and renewables balance tight capacity amid EV charging growth, heat pumps, and blackout risk across the U.S.

Key Points

Texas power grid is ERCOT-run and isolated, balancing natural gas and wind amid extreme weather and electrification.

✅ Isolated from other U.S. grids, limited import support

✅ Vulnerable to extreme heat, winter storms, low wind

✅ Demand growth from EVs and heat pumps stresses capacity

Texas has a unique state-run power grid facing a Texas grid crisis that has raised concerns, but its issues with extreme weather, and balancing natural gas and wind, hold lessons for an entire U.S. at risk for power outages from climate change.

Grid operator the Electric Reliability Council of Texas, or ERCOT, which has drawn criticism from Elon Musk recently, called on consumers to voluntarily reduce power use on Monday when dangerous heat gripped America’s second-most populous state.

The action paid off as the Texas grid avoided blackouts — and a repeat of its winter crisis — despite record or near-record temperatures that depleted electric supplies amid a broader supply-chain crisis affecting utilities this summer, and risked lost power to more than 26 million customers. ERCOT later on Monday lifted the call for conservation.

For sure, it’s a unique situation, as the state-run power grid system runs outside the main U.S. grids. Still, all Americans can learn from Texas about the fragility of a national power grid that is expected to be challenged more frequently by hot and cold weather extremes brought on by climate change, including potential reliability improvements policymakers are weighing.

The grid will also be tested by increased demand to power electric vehicles (EVs) and conversions to electric heat pumps — all as part of a transition to a “greener” future.

Why is Texas different?
ERCOT, the main, but not only, Texas grid, is unique in its state-run, and not regional, format used by the rest of the country. Because it’s an energy-rich state, Texas has been able to set power prices below those seen in other parts of the country, and its independence gives it more pricing authority, while lawmakers consider market reforms to avoid blackouts. But during unusual strain on the system, such as more people blasting their air conditioners longer to combat a record heat wave, it also has no where else to turn.

A lethal winter power shortage in February 2021, during a Texas winter storm that left many without power and water, notoriously put the state and its independent utility in the spotlight when ERCOT failed to keep residents warm and pipes from bursting. Texas’s 2021 outage left more than 200 people dead and rang up $20 billion in damage. Fossil-fuel CL00, 0.80% backers pointed to the rising use of intermittent wind power, which generates 23% of Texas’s electricity. Others said natural-gas equipment was frozen under the extreme conditions.

This week, ERCOT is asking for voluntary conservation between 2 p.m. and 8 p.m. local time daily due to record high electricity demand from the projected heat wave, and also because of low wind. ERCOT said current projections show wind generation coming in at less than 10% of capacity. ERCOT stressed that no systemwide outages are expected, and Gov. Greg Abbott has touted grid readiness heading into fall, but it was acting preemptively.

A report late last year from the North American Electric Reliability Corp. (NERC) said the Texas system without upgrades could see a power shortfall of 37% in extreme winter conditions. NERC’s outlook suggested the state and ERCOT isn’t prepared for a repeat of weather extremes.

Ontario Utilities Hurricane Irma Aid mobilizes Hydro One and Toronto Hydro crews to Tampa Bay, Florida, restoring power outages with bucket trucks, lineworkers, and mutual aid alongside Florida Power & Light after catastrophic damage.

Key Points

Mutual aid sending Hydro One and Toronto Hydro crews to Florida to restore power after Hurricane Irma.

✅ 205 workers, 52 bucket trucks, 30 support vehicles deployed

✅ Crews assist Tampa Bay under FPL mutual aid agreements

✅ Weeks-long restoration projected after catastrophic outages

Hurricane Irma has left nearly 7 million homes in the southern United States without power and two Ontario hydro utility companies are sending teams to help out as part of Canadian power crews responding to the disaster.

Toronto Hydro is sending 30 staffers to aid in the restoration efforts in Tampa Bay while Hydro One said Sunday night that it would send 175 employees after receiving a request from Florida Power and Light.

“I've been on other storms down in the states and they are pretty happy to see you especially when they find out you're from Canada,” Dean Edwards, one of the Hydro One employees heading to Florida, told CTV Toronto.

Most of the employees are expected to cross the border on Monday afternoon and arrive Wednesday.

Among the crews, Hydro One says it will send 150 lines and forestry staff, as well as 25 supporting resources, including mechanics, to help. Crews will bring 52 bucket trucks to Florida, as well as 30 other vehicles, reflecting their Ontario storm restoration experience with large-scale deployments, and pieces of equipment to transport and replace poles.

Hurricane Irma has claimed at least 45 lives in the Caribbean and United States thus far. Officials estimate that restoring power to Florida will take weeks to bring power back online.

“I’m sure a lot of people wish they could go down and help, fortunately our job is geared towards that so we're going to go down there to do our best and represent Canada,” said Blair Clarke, who’s making his first trip over the border.

Hydro One has reciprocal arrangements with other North American utilities to help with significant power outages, and its employees have provided COVID-19 support in Ontario as part of broader emergency efforts. All the costs are covered by the utility receiving the help.

In the past, the utility has sent crews to Massachusetts, Michigan, Florida, Ohio, Vermont, Washington, DC, and the Carolinas, while Sudbury Hydro crews have worked to reconnect service after storms at home as well. In 2012, 225 Hydro One employees travelled to Long Island, N.Y., to help out with Hurricane Sandy.

“This is what our guys and gals do,” Natalie Poole-Moffat, vice president of Corporate Affairs for Hydro One, told CP24. “They’re fabulous at it and we’re really proud of the work they do.”

✅ Nuclear tech supports healthcare, agriculture, COVID-19 tests

Pakistan is utilising its nuclear technology to achieve its full potential by generating electricity, aligning with China's steady nuclear development trends, and attaining socio-economic development goals outlined by the United Nations Sustainable Development Goals.

This was stated by Pakistan Atomic Energy Commission (PAEC) Chairperson Muhammad Naeem on Tuesday while addressing the 64th International Atomic Energy Agency (IAEA) General Conference (GC) which is being held in Vienna from September 21, a forum taking place amid regional milestones like the UAE's first Arab nuclear plant startup as well.

Regarding nuclear security, the PAEC chief stated that Pakistan considered it as a national responsibility and that it has developed a comprehensive and stringent safety and security regime, echoing IAEA praise for China's nuclear security in the region, which is regularly reviewed and upgraded in accordance with IAEA's guidelines.

Many delegates are attending the event through video link due to the novel coronavirus (Covid-19) pandemic.

On the first day of the conference, IAEA Director General Rafael Mariano Grossi highlighted the role of the nuclear watchdog in the monitoring and verification of nuclear activities across the globe, as seen in Barakah Unit 1 at 100% power milestones reported worldwide.

He also talked about the various steps taken by the IAEA to help member states contain the spread of coronavirus such as providing testing kits etc.

In a recorded video statement, the PAEC chairperson said that Pakistan has a mutually beneficial relationship with IAEA, similar to IAEA assistance to Bangladesh on nuclear power development efforts. He also congratulated Ambassador Azzeddine Farhane on his election to become the President of the 64th GC and assured him of Pakistan's full support and cooperation.

Naeem stated that as a clean, affordable and reliable source, nuclear energy can play a key role, with India's nuclear program moving back on track, in fighting climate change and achieving the Sustainable Development Goals (SDGs).

The PAEC chief informed the audience that two 1,100-megawatt (MW) nuclear power plants are near completion and, like the UAE grid connection milestone, are expected to be connected to the national grid next year.

He also highlighted the role of PAEC in generating electricity through nuclear power plants, while also helping the country achieve the socio-economic development goals outlined under the United Nations SDGs through the application of nuclear technology in diverse fields like agriculture, healthcare, engineering and manufacturing, human resource development and other sectors.
