One of two nuclear reactors at the Diablo Canyon power plant remains shut down because of a blown fuse.

A spokeswoman for Pacific Gas & Electric said the company doesn't know why the fuse blew, and can't say when the reactor will be operating again.

PG&E spokeswoman Emily Christensen says a fan for cooling a transformer had stopped on June 30, which set off an alarm and prompted operators to shut down the reactor.

PG&E says the shutdown doesn't pose a safety hazard and the plant's other reactor is operating at full power.

Diablo Canyon's two reactors in California's Central Coast produce about 2,300 megawatts of electricity. PG&E says that's about 10 percent of all electricity generated in California.

Shell says electricity to meet 60 percent of China's energy use by 2060

China 2060 Carbon-Neutral Energy Transition projects tripled electricity, rapid electrification, wind and solar dominance, scalable hydrogen, CCUS, and higher carbon pricing to meet net-zero goals while decarbonizing heavy industry and transport.

 

Key Points

Shell's outlook for China to reach net zero by 2060 via electrification, renewables, hydrogen, CCUS, and carbon pricing.

✅ Power supply to 60% of energy; generation triples by 2060.

✅ Wind and solar reach 80% of electricity; coal declines sharply.

✅ Hydrogen scales to 17 EJ; CCUS and carbon pricing expand.

 

China may triple electricity generation to supply 60 percent of the country's total energy under Beijing's carbon-neutral goal by 2060, up from the current 23 per cent, according to Royal Dutch Shell.

Shell is one of the largest global investors in China's energy sector, with business covering gas production, petrochemicals and a retail fuel network. A leading supplier of liquefied natural gas, it has recently expanded into low-carbon business such as hydrogen power and electric vehicle charging.

In a rare assessment of the country's energy sector by an international oil major, Shell said China needed to take quick action this decade to stay on track to reach the carbon-neutrality goal.

China has mapped out plans to reach peak emissions by 2030, and aims to reduce coal power production over the coming years, but has not yet revealed any detailed carbon roadmap for 2060.

This includes investing in a reliable and renewable power system, including compressed air generation, and demonstrating technologies that transform heavy industry using hydrogen, biofuel and carbon capture and utilization.

"With early and systematic action, China can deliver better environmental and social outcomes for its citizens while being a force for good in the global fight against climate change," Mallika Ishwaran, chief economist of Shell International, told a webinar hosted by the company's China business.

Shell expects China's electricity generation to rise three-fold to more than 60 exajoules (EJ) in 2060 from 20 EJ in 2020, even amid power supply challenges reported recently.

Solar and wind power are expected to surpass coal as the largest sources of electricity by 2034 in China, reflecting projections that renewables will eclipse coal globally by mid-decade, versus the current 10 percent, rising to 80 percent by 2060, Shell said.

Hydrogen is expected to scale up to 17 EJ, or equivalent to 580 million tonnes of coal by 2060, up from almost negligible currently, adding over 85 percent of the hydrogen will be produced through electrolysis, supported by PEM hydrogen R&D across the sector, powered by renewable and nuclear electricity, Shell said.

Hydrogen will meet 16 percent of total energy use in 2060 with heavy industry and long-distance transport as top hydrogen users, the firm added.

The firm also expects China's carbon price to rise to 1,300 yuan (CDN$256.36) per tonne in 2060 from 300 yuan in 2030.

Nuclear, on a steady development track, and biomass will have niche but important roles for power generation in the years to come, Shell said.

Electricity generated from biomass, combined with carbon, capture, utilization and storage (CCUS), provide a source of negative emissions for the rest of the energy system from 2053, it added.

Duke Energy Florida's smart-thinking grid improves response, power restoration for customers during Hurricane Ian

Self-healing grid technology automatically reroutes power to reduce outages, speed restoration, and boost reliability during storms like Hurricane Ian in Florida, leveraging smart grid sensors, automation, and grid hardening to support Duke Energy customers.

 

Key Points

Automated smart grid systems that detect faults and reroute power to minimize outages and accelerate restoration.

✅ Cuts outage duration via automated fault isolation

✅ Reroutes electricity with sensors and distribution automation

✅ Supports storm resilience and faster field crew restoration

 

As Hurricane Ian made its way across Florida, where restoring power in Florida can take weeks in hard-hit areas, Duke Energy's grid improvements were already on the job helping to combat power outages from the storm.

Smart, self-healing technology, similar to smart grid improvements elsewhere, helped to automatically restore more than 160,000 customer outages and saved nearly 3.3 million hours (nearly 200 million minutes) of total lost outage time.

"Hurricane Ian is a strong reminder of the importance of grid hardening and storm preparedness to help keep the lights on for our customers," said Melissa Seixas, Duke Energy Florida state president. "Self-healing technology is just one of many grid improvements that Duke Energy is making to avoid outages, restore service faster and increase reliability for our customers."

Much like the GPS in your car can identify an accident ahead and reroute you around the incident to keep you on your way, self-healing technology is like a GPS for the grid. The technology can quickly identify power outages and alternate energy pathways to restore service faster for customers when an outage occurs.

Additionally, self-healing technology provides a smart tool to assist crews in the field with power restoration after a major storm like Ian, helping reduce outage impacts and freeing up resources to help restore power in other locations.

Three days after Hurricane Ian exited the state, Duke Energy Florida wrapped up restoration of approximately 1 million customers. This progress enabled the company to deploy more than 550 Duke Energy workers from throughout Florida, as well as contractors from across the country, to help restore power for Lee County Electric Cooperative customers.

Crews worked in Cape Coral and Pine Island, one of the hardest-hit areas in the storm's path, as Canadian power crews have in past storms, and completed power restoration for the majority of customers on Pine Island within approximately one week after arriving to the island.

Prior to Ian in 2022, smart, self-healing technology had helped avoid nearly 250,000 extended customer outages in Florida, similar to Hydro One storm recovery efforts, saving around 285,000 hours (17.1 million minutes) of total lost outage time.

Duke Energy currently serves around 59% of customers in Florida with self-healing capabilities on its main power distribution lines, with a goal of serving around 80% over the next few years.

Ontario energy minister asks for early report exploring a halt to natural gas power generation

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.

Hydro One, Avista to ask U.S. regulator to reconsider order against acquisition

Hydro One Avista Takeover faces Washington UTC scrutiny as regulators deny approval; companies plan a reconsideration petition, citing acquisition terms, governance concerns, merger risks, EPS dilution, and balance sheet impacts across regulated utility operations.

 

Key Points

A $6.7B bid by Hydro One to buy Avista, denied by Washington UTC on governance risk, under reconsideration petition.

✅ UTC denied over potential provincial interference.

✅ Petition for reconsideration due by Dec. 17.

✅ Deal seen diluting EPS, weakening balance sheet.

 

Hydro One Ltd. and Avista Corp. say they plan to formally request that the Washington Utilities and Transportation Commission reconsider its order last week denying approval of the $6.7-billion takeover, which previously received U.S. antitrust clearance from federal regulators, of the U.S.-based energy utility.

The two companies say they will file a petition no later than Dec. 17 but haven't indicated on what grounds they are making the request, even as investor concerns about Hydro One persist.

Under Washington State law, the UTC has 20 days to consider the petition, otherwise it is deemed to be denied.

If it reconsiders its decision, the UTC can modify the prior order or take any actions it deems appropriate, similar to provincial rulings such as the OEB decision on Hydro One's first combined T&D rates, including extending deliberations.

Washington State regulators said they would not allow Ontario's largest utility to buy Avista for fear the provincial government, which owns 47 per cent of Hydro One's shares and recently prompted a CEO and board exit at the utility, might meddle in Avista's operations.

Hydro One's shares have risen since the order because the deal, announced in July 2017, would have eroded earnings per share and weakened Hydro One's balance sheet, according to analysts, even as the company reported a one-time-boosted Q2 profit earlier this year.

Smaller, cheaper, safer: Next-gen nuclear power, explained

MARVEL microreactor debuts at Idaho National Laboratory as a 100 kW, liquid-metal-cooled, zero-emissions generator powering a nuclear microgrid, integrating wind and solar for firm, clean energy in advanced nuclear applications research.

 

Key Points

A 100 kW, liquid-metal-cooled INL reactor powering a nuclear microgrid and showcasing zero-emissions clean energy.

✅ 100 kW liquid-metal-cooled microreactor at INL

✅ Powers first nuclear microgrid for applications testing

✅ Integrates with wind and solar for firm clean power

 

Inside the Transient Reactor Test Facility, a towering, windowless gray block surrounded by barbed wire, researchers are about to embark on a mission to solve one of humanity’s greatest problems with a tiny device.

Next year, they will begin construction on the MARVEL reactor. MARVEL stands for Microreactor Applications Research Validation and EvaLuation. It’s a first-of-a-kind nuclear power generator with a mini-reactor design that is cooled with liquid metal and produces 100 kilowatts of energy. By 2024, researchers expect MARVEL to be the zero-emissions engine of the world’s first nuclear microgrid at Idaho National Laboratory (INL).

“Micro” and “tiny,” of course, are relative. MARVEL stands 15 feet tall, weighs 2,000 pounds, and can fit in a semi-truck trailer. But it's minuscule compared to conventional nuclear power plants, which span acres, produces gigawatts of electricity to power whole states, and can take more than a decade to build.

For INL, where scientists have tested dozens of reactors over the decades across an area three-quarters the size of Rhode Island, it’s a radical reimagining of the technology. This advanced reactor design could help overcome the biggest obstacles to nuclear energy: safety, efficiency, scale, cost, and competition. MARVEL is an experiment to see how all these pieces could fit together in the real world.

“It’s an applications test reactor where we’re going to try to figure out how we extract heat and energy from a nuclear reactor and apply it — and combine it with wind, solar, and other energy sources,” said Yasir Arafat, head of the MARVEL program.

The project, however, comes at a time when nuclear power is getting pulled in wildly different directions, from phase-outs to new strategies like the UK’s green industrial revolution that shapes upcoming reactors.

Germany just shut down its last nuclear reactors. The U.S. just started up its first new reactor in 30 years, underscoring a shift. France, the country with the largest share of nuclear energy on its grid, saw its atomic power output decline to its lowest since 1988 last year. Around the world, there are currently 60 nuclear reactors under construction, with 22 in China alone.

But the world is hungrier than ever for energy. Overall electricity demand is growing: Global electricity needs will increase nearly 70 percent by 2050 compared to today’s consumption, according to the Energy Information Administration. At the same time, the constraints are getting tighter. Most countries worldwide, including the U.S., have committed to net-zero goals by the middle of the century, even as demand rises.

To meet this energy demand without worsening climate change, the U.S. Energy Department’s report on advanced nuclear energy released in March said, “the U.S. will need ~550–770 [gigawatts] of additional clean, firm capacity to reach net-zero; nuclear power is one of the few proven options that could deliver this at scale.”

The U.S. government is now renewing its bets on nuclear power to produce steady electricity without emitting greenhouse gases. The Bipartisan Infrastructure Law included $6 billion to keep existing nuclear power plants running. In addition, the Inflation Reduction Act, the U.S. government’s largest investment in countering climate change, includes several provisions to benefit atomic power, including tax credits for zero-emissions energy.

“It’s a game changer,” said John Wagner, director of INL.

The tech sector is jumping in, too, as atomic energy heats up across startups and investors. In 2021, venture capital firms poured $3.4 billion into nuclear energy startups. They’re also pouring money into even more far-out ideas, like nuclear fusion power. Public opinion has also started moving. An April Gallup poll found that 55 percent of Americans favour and 44 percent oppose using atomic energy, the highest levels of support in 10 years.

New York Faces Soaring Energy Bills

New York faces soaring energy bills as utilities seek record rate hikes, aging grid infrastructure demands upgrades, and federal renewable policies shift. Consumers struggle with affordability, late payments, and rising costs of delivery and energy supply across the state.

 

Why is New York Facing Soaring Energy Bills?

New York faces soaring energy bills because utilities are raising rates to cover the costs of grid upgrades, inflation, and policy-driven changes in energy supply.

✅ Utilities seek double-digit rate hikes across the state

✅ Aging infrastructure and storm repairs increase delivery costs

✅ Federal policies and gas dependence push energy prices higher

New Yorkers are bracing for another wave of energy bill increases as utilities seek record-high rate hikes and policy changes ripple through the state’s power system. Electric bills in New York are the highest they’ve been in over a decade, and more than a million households are now at least two months behind on payments, a sign of pandemic energy insecurity that continues to strain budgets, owing utilities nearly $2 billion.

Record numbers of households have had their electricity or gas shut off this year — more than 61,000 in May alone — despite pandemic shut-off suspensions that had offered temporary relief, the highest the Public Utility Law Project (PULP) has ever recorded. “This August was the group’s busiest month ever,” said Laurie Wheelock, PULP’s executive director, citing a surge in calls to its hotline. “The top concern on people’s minds: rate hikes.”

Utilities across the state are pushing for significant price increases, citing aging infrastructure, the need for climate adaptation, and higher operating costs, as California regulators face calls for action amid rising bills. “We used to see single-digit rate hikes and now we see double-digit rate hikes,” said Jessica Azulay, executive director of the Alliance for a Green Economy. “That’s a new normal that is unacceptable.”

Several utilities have requested delivery rate increases of 25 percent or more, with some proposals as high as 39 percent. Upstate utilities NYSEG and RG&E are seeking to raise electric and gas bills by about $33 a month, although regulators are unlikely to approve the full amount.

The companies argue the hikes are needed “to pay for rebuilding an aging grid and expanding its capacity to meet residents’ and businesses’ service demands,” including storm repairs. They also claim the plan would create more than 1,000 jobs.

James Denn, a spokesperson for the Public Service Commission (PSC), said much of the cost pressure stems from “inflation, higher interest rates, supply chain disruptions, the global push to upgrade electrical infrastructure, and, most recently, the rising risk and uncertainty from tariffs,” trends reflected in U.S. electricity price data over the past two years.

While some have blamed New York’s clean-energy transition, a PSC report found that state climate policies account for only 5 to 9.5 percent of the average household’s electric bill, or approximately $10 to $12 per month. The bulk of the increases still come from traditional spending on infrastructure, storm resilience, and system expansion.

On the supply side, costs are rising too. President Donald Trump’s recent policies have threatened renewable-energy investment nationwide, even as states’ renewable ambitions carry significant costs, potentially adding to New York’s woes. His July “megabill” phases out a 30 percent federal tax credit for solar and wind unless projects begin construction by mid-2026. Industry experts warn that the changes could make renewables “more expensive to build” and “increase reliance on gas.”

“It just means more expensive power,” said Marguerite Wells of the Alliance for Clean Energy New York.

The state estimates Trump’s policy shifts could cost New York $60 billion in lost renewable investment. With fewer clean-energy projects moving forward, gas — which already supplies roughly half of the state’s electricity — will remain the dominant source, tying energy prices to volatile global markets and the kinds of price drivers seen in California in recent years.

Governor Kathy Hochul has called affordability “our greatest short-term challenge,” while consumer advocates are demanding reforms to reduce utility profits and overhaul “rate design,” and to strengthen protections such as the emergency disconnection moratorium that applies during declared emergencies.

“There is definitely a groundswell of concern,” Wheelock said. “We go to meetings and we’re getting questions about rate design, like, ‘What is the revenue decoupling mechanism?’ Never had that question before.”
