Gas power plant planned for Mississauga

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.

Hydro One and Alectra Hamilton Grid Upgrades will modernize electricity infrastructure with new transformers, protection devices, transmission and distribution improvements, tree trimming, pole replacements, and line refurbishments to boost reliability and reduce outages across region.

Key Points

A $250M plan to modernize Hamilton transmission and distribution, reducing outages and improving reliability by 2022.

✅ New transformers and protection devices to cut outages

✅ Refurbished 1915 line powering Hamilton West Mountain

✅ Tree trimming and pole replacements across 1,260 km

Hydro One Networks Inc. (Hydro One), Ontario's largest electricity transmission and distribution company whose delivery rates recently increased, and Alectra Utilities have announced they expect to complete approximately $250 million of work in the Hamilton area by 2022 to upgrade local electricity infrastructure and improve service reliability.

As part of these plans to strengthen the electricity grid in the Hamilton region, where utilities must adapt to climate change pressures, investments are expected to include:

installing quieter, more efficient transformers in four stations across Hamilton to assist in reducing the number of outages;
replacing protection and switching devices across the city to shorten outage restoration times, reflecting how transmission line work underpins reliability;
refurbishing a power line originally installed in 1915 that is critical to powering the Hamilton West Mountain area; and,
trimming hazardous trees across more than 1,260 km of overhead powerlines and replacing more than 270 poles.
Hydro One will be working with Alectra Utilities to replace aging infrastructure at Elgin transmission station.

"A loss of power grinds life to a halt, impacting businesses, families and productivity. That's why Hydro One is partnering with Alectra Utilities to support a growing local economy in Hamilton, while improving power reliability for its residents," said Jason Fitzsimmons, Chief Corporate Affairs and Customer Care Officer. "Replacing aging infrastructure and modernizing equipment is part of our plan to build a stronger, safer and more reliable electricity system for Ontario now and into the future." 

"Partnering with Hydro One to invest in our local community will create a safer, more resilient and reliable system for the future," said Max Cananzi, President, Alectra Utilities.  "In addition to investments in the transmission system, Alectra Utilities also plans to invest $235 million over the next five years to renew, upgrade and connect customers to the electrical distribution and supporting systems in Hamilton. Investments in the transmission and distribution systems in Hamilton will contribute to the long-term sustainability of our communities."

"I am pleased to see Hydro One and Alectra investing in modernizing local electricity infrastructure and improving reliability," said Member of Provincial Parliament, Donna Skelly.  "Safe and reliable power is essential to supporting local families, businesses and our community."

Across Ontario, First Nations call for action on urgently needed transmission lines highlight the importance of timely grid investments.

Hydro One's investments included in this announcement are captured in its previously disclosed future capital expenditures, amid proposed projects like the Meaford hydro project across Ontario.

Much of Hydro One's electricity system was built in the 1950s, and replacing aging assets is critical as delays affecting a cross-border transmission line elsewhere have shown. Its three-year, $5 billion investment plan supports safe and reliable power to communities across Ontario, and strong regulatory oversight illustrated by the ATCO Electric penalty helps maintain public trust.

Octopus Energy and DTEK Partnership explores licensing the Kraken platform to rebuild Ukraine's power grid, enabling real-time analytics, smart-home integration, renewable energy orchestration, and distributed resilience amid ongoing attacks on critical energy infrastructure.

Key Points

Collaboration to deploy Kraken and renewables to modernize Ukraine's grid with analytics, smart control, and resilience.

✅ Kraken licensing for grid operations and customer analytics

✅ Shift to distributed solar, wind, and smart-home devices

✅ Real-time monitoring to mitigate outages and cyber risks

Octopus Energy, a prominent UK energy firm, has begun preliminary conversations with Ukraine's DTEK regarding potential collaboration to refurbish Ukraine's heavily damaged electric infrastructure as ongoing strikes threaten the power grid across the country.

Persistent assaults by Russia on Ukraine's power network, including a five-hour attack on Kyiv's grid, have led to significant electricity shortages in numerous regions.

Octopus Energy, the largest electricity and second-largest gas supplier in the UK, collaborates with energy firms in 17 countries using its Kraken software platform, and Ukraine joined Europe's power grid with unprecedented speed to bolster resilience. This platform is currently being trialled by the Abu Dhabi National Energy Company (Taqa) for power and water customers in the UAE.

A spokesperson from Octopus revealed to The National that the company is "in the early stages of discussions with DTEK to explore potential collaborative opportunities.”

One of the possibilities being considered is licensing Octopus's Kraken technology platform to DTEK, a platform that presently serves 54 million customer accounts globally.

Russian drone and missile attacks, which initially targeted Ukrainian ports and export channels last summer, shifted focus to energy infrastructure by October, ahead of the winter season as authorities worked to protect electricity supply before winter across the country.

These initial talks between Octopus CEO Greg Jackson and DTEK CEO Maxim Timchenko took place at the World Economic Forum in Davos, set against the backdrop of these ongoing challenges.

DTEK, Ukraine's leading private energy provider, might integrate Octopus's advanced Kraken software to manage and optimize data systems ranging from large power plants to smart-home devices, with a growing focus on protecting the grid against emerging threats.

Kraken is described by Octopus as a comprehensive technology platform that supports the entire energy supply chain, from generation to billing. It enables detailed analytics, real-time monitoring, and control of energy devices like heat pumps and electric vehicles, underscoring the need to counter cyber weapons that can disrupt power grids as systems become more connected.

Octopus Energy, with its focus on renewable sources, can also assist Ukraine in transitioning its power infrastructure from centralized coal-fired power stations, which are vulnerable targets, to a more distributed network of smaller solar and wind projects.

DTEK, serving approximately 3.5 million customers in the Kyiv, Donetsk, and Dnipro regions, is already engaged in renewable initiatives. The company constructed a wind farm in southern Ukraine within nine months last year and has plans for additional projects in Italy and Croatia.

Emphasizing the importance of rebuilding Ukraine's economy, Timchenko recently expressed at Davos the need for Ukrainian and international companies to work together to create a sustainable future for Ukraine, noting that incidents such as Russian hackers accessed U.S. control rooms highlight the urgency.

Alberta Solar Power is accelerating as renewable energy investment, PPAs, and utility-scale projects expand the grid, with independent power producers and foreign capital outperforming AESO forecasts in oil-and-gas-rich markets across Alberta and Calgary.

Key Points

Alberta Solar Power is a fast-growing provincial market, driven by PPAs and private investment, outpacing AESO forecasts.

✅ Utility-scale projects and PPAs expand capacity beyond AESO outlooks

✅ Private and foreign capital drive independent power producers

✅ Costs near $70/MWh challenge >$100/MWh assumptions

Solar power is beating expectations in oil and gas rich Alberta, where the renewable energy source is poised to expand dramatically amid a renewable energy surge in the coming years as international power companies invest in the province.

Fresh capital is being deployed in the Alberta’s electricity generation sector for both renewable and natural gas-fired power projects after years of uncertainty caused by changes and reversals in the province’s power market, said Duane Reid-Carlson, president of power consulting firm EDC Associates, who advises renewable power developers on electric projects in the province.

“From the mix of projects that we see in the queue at the (Alberta Electric System Operator) and the projects that have been announced, Alberta, a powerhouse for both green energy and fossil fuels, has no shortage of thermal and renewable projects,” Reid-Carlson said, adding that he sees “a great mix” of independent power companies and foreign firms looking to build renewable projects in Alberta.

Alberta is a unique power market in Canada because its electricity supply is not dominated by a Crown corporation such as BC Hydro, Hydro One or Hydro Quebec. Instead, a mix of private-sector companies and a few municipally owned utilities generate electricity, transmit and distribute that power to households and industries under long-term contracts.

Last week, Perimeter Solar Inc., backed by Danish solar power investor Obton AS, announced Sept. 30 that it had struck a deal to sell renewable energy to Calgary-based pipeline giant TC Energy Corp. with 74.25 megawatts of electricity from a new 130-MW solar power project immediately south of Calgary. Neither company disclosed the costs of the transaction or the project.

“We are very pleased that of all the potential off-takers in the market for energy, we have signed with a company as reputable as TC Energy,” Obton CEO Anders Marcus said in a release announcing the deal, which it called “the largest negotiated energy supply agreement with a North American energy company.”

Perimeter expects to break ground on the project, which will more than double the amount of solar power being produced in the province, by the end of this year.

A report published Monday by the Energy Information Administration, a unit of the U.S. Department of Energy, estimated that renewable energy powered 3 per cent of Canada’s energy consumption in 2018.

Between the Claresholm project and other planned solar installations, utility companies are poised to install far more solar power than the province is currently planning for, even as Alberta faces challenges with solar expansion today.

University of Calgary adjunct professor Blake Shaffer said it was “ironic” that the Claresholm Solar project was announced the exact same day as the Alberta Electric System Operator released a forecast that under-projected the amount of solar in the province’s electric grid.

The power grid operator (AESO) released its forecast on Sept. 30, which predicted that solar power projects would provide just 1 per cent of Alberta’s electricity supply by 2030 at 231 megawatts.

Shaffer said the AESO, which manages and operates the province’s electricity grid, is assuming that on a levelized basis solar power will need a price over $100 per megawatt hour for new investment. However, he said, based on recent solar contracts for government infrastructure projects, the cost is closer to $70 MW/h.

Most forecasting organizations like the International Energy Agency have had to adjust their forecasts for solar power adoption higher in the past, as growth of the renewable energy source has outperformed expectations.

Calgary-based Greengate Power has also proposed a $500-million, 400-MW solar project near Vulcan, a town roughly one-hour by car southeast of Calgary.

“So now we’re getting close to 700 MW (of solar power),” Shaffer said, which is three times the AESO forecast.

California Wildfire Power Shut-Offs escalate as PG&E imposes blackouts amid high winds, Getty and Kincade fires, mass evacuations, Sonoma County threats, and a state of emergency, drawing regulatory scrutiny over grid safety and outage scope.

Key Points

Planned utility outages to curb wildfire risk during extreme winds, prompting evacuations and regulatory scrutiny.

✅ PG&E preemptive blackouts under regulator inquiry

✅ Getty and Kincade fires drive mass evacuations

✅ Sonoma County under threat amid high winds

Pacific Gas & Electric (PG&E) already faces an investigation by regulators after cutting supplies to 970,000 homes and businesses amid California blackouts that raised concerns.

It announced that another 650,000 properties would face precautionary shut-offs.

Wildfires fanned by the strong winds are raging in two parts of the state.

Thousands of residents near the wealthy Brentwood neighbourhood of Los Angeles have been told to evacuate because of a wildfire that began early on Monday.

Further north in Sonoma County, a larger fire has forced 180,000 people from their homes.

California's governor has declared a state-wide emergency.

What about the power cuts?

On Monday regulators announced a formal inquiry into whether energy utilities broke rules by pre-emptively cutting power to an estimated 2.5 million people, amid a blackouts policy debate that intensified, as wildfire risks soared.

They did not name any utilities but analysts said PG&E was responsible for the bulk of the "public safety power shut-offs", and later faced a Camp Fire guilty plea that underscored its liabilities.

The company filed for bankruptcy in January after facing hundreds of lawsuits from victims of wildfires in 2017 and 2018.

Of the 970,000 properties hit by the most recent cuts, under half had their services back by Monday, and some sought help through wildfire assistance programs, the Associated Press reported.

Despite criticism that the precautionary blackouts were too widespread and too disruptive, PG&E said more would come on Tuesday and Wednesday because further strong winds were expected.

The company said it had logged more than 20 preliminary reports of damage to its network from the most recent windstorm.

In a video posted to Twitter on Saturday, Governor Gavin Newsom said the power cuts were "infuriating everyone, and rightfully so".

Where are the fires now?

In Los Angeles, the Getty Fire has burned over 600 acres (242 ha) and about 10,000 buildings are in the mandatory evacuation zone.

At least eight homes have been destroyed and five others damaged.

"If you are in an evacuation zone, don't screw around," Mr Schwarzenegger tweeted. "Get out."

LA fire chief Ralph Terrazas said fire crews had been "overwhelmed" by the scale of the fires.

"They had to make some tough decisions on which houses they were able to protect," he said.

"Many times it depends on where the ember lands. I saw homes that were adjacent to homes that were totally destroyed, without any damage."

In northern California, schools remain closed in Sonoma County, where tens of thousands of homes and businesses are under threat.

Sonoma has been ravaged by the Kincade Fire, which started on Wednesday and has burned through 50,000 acres of land, fanned by the winds.

The Kincade Fire began seven minutes after a nearby power line was damaged, and power lines may have started fires according to reports, but PG&E has not yet confirmed if the power glitch started the blaze.

About 180,000 people have been ordered to evacuate, with roads around Santa Rosa north of San Francisco packed with cars as people tried to flee.

There are fears the flames could cross the 101 highway and enter areas that have not seen wildfires since the 1940s.

Demand Flexibility Service rewards households and businesses for shifting peak-time electricity use, enhancing grid balancing, energy security, and net zero goals with ESO and Ofgem support, virtual power plants, and 2GW capacity this winter.

Key Points

A grid program paying homes and businesses to shift peak demand, boosting energy security and lowering winter costs.

✅ Pays £3,000/MWh for reduced peak-time usage

✅ Targets at least 2GW via virtual power plants

✅ Rolled out by suppliers with Ofgem and ESO

This month we published our analysis of the British electricity system this winter. Our message is clear: in the base case our analysis indicates that supply margins are expected to be adequate, however this winter will undoubtedly be challenging, with high winter energy costs adding pressure. Therefore, all of us in the electricity system operator (ESO) are working round the clock to manage the system, ensure the flow of energy and do our bit to keep costs down for consumers.

One of the tools we have developed is the demand flexibility service, designed to complement efforts to end the link between gas and electricity prices and reduce bills. From November, this new capability will reward homes and businesses for shifting their electricity consumption at peak times. And we are working with the government, businesses and energy providers to encourage as high a level of take-up as possible. We are confident this innovative approach can provide at least 2 gigawatts of power – about a million homes’ worth.

What began as an initiative to help achieve net zero and keep costs down is also proving to be an important tool in ensuring Britain’s energy security, alongside the Energy Security Bill progressing into law.

We are particularly keen to get businesses involved right across Britain. When the Guardian first reported on this service we had calls from businesses ranging from multinationals to an owner of a fish and chip shop asking how they could do their bit and get signed up.

We can now confirm our proposals for how much people and businesses can be paid for shifting their electricity use outside peak times. We anticipate paying a rate of £3,000 per megawatt hour, reflecting the dynamics of UK natural gas and electricity markets today. Businesses and homes can become virtual power plants and, crucially, get paid like one too. For a consumer that could mean a typical household could save approximately £100, and industrial and commercial businesses with larger energy usage could save multiples of this.

We are working with Ofgem to get this scheme launched in November and for it to be rolled out through energy suppliers. If you are interested in participating, or understanding what you could get paid, please contact your energy supplier.

Innovations such as these have never mattered more. Vladimir Putin’s unlawful aggression means we are facing unprecedented energy market volatility, across the continent where Europe’s worst energy nightmare is becoming reality, and pressures on energy supplies this winter.

As a result of Russia’s war in Ukraine, European gas is scarce and prices are high, prompting Europe to weigh emergency measures to limit electricity prices amid the crisis. Alongside this, France’s nuclear fleet has experienced a higher number of outages than expected. Energy shortages in Europe could have knock-on implications for energy supply in Britain.

We have put in place additional contingency arrangements for this winter. For example, the ability to call on generators to fire-up emergency coal units, even as the crisis is a wake-up call to ditch fossil fuels for many, giving Britain 2GW of additional capacity.

We need to be clear, it is possible that without these measures supply could be interrupted for some customers for limited periods of time. This could eventually force us to initiate a temporary rota of planned electricity outages, meaning that some customers could be without power for up to three hours at a time through a process called the electricity supply emergency code (ESEC).

Under the ESEC process we would advise the public the day before any disconnections. We are working with government and industry on planning for this so that the message can be spread across all communities as quickly and accurately as possible. This would include press conferences, social media campaigns, and working with influencers in different communities.
