Japan’s Tokyo Electric Power said it hoped to achieve a “cold shutdown” of its crippled Fukushima Daiichi nuclear plant in six to nine months, setting a time frame for bringing the world’s worst nuclear crisis in 25 years under control.

Within three months Tokyo Electric said it planned to cool reactors and spent fuel at the nuclear plant to a stable level and get radiation leaks on a downward trend.

In another three to six months Asia’s largest utility aims to secure a “cold shutdown” at the plant, a state in which the water cooling fuel rods is below 100 C and the reactors are considered stable.

The firm, commonly known as TEPCO, has been struggling to stabilize the Fukushima complex 240 kilometres north of Tokyo, which was seriously damaged by the March 11 earthquake and tsunami and has been leaking radiation.

Shares of TEPCO, a blue-chip firm established 60 years ago, have lost three-fourths of their value since the quake amid worries over whether it would survive the crisis, with one analyst estimating compensation claims could reach $130 billion.

“This is the biggest crisis since the founding of our company,” TEPCO Chairman Tsunehisa Katsumata told a briefing in Tokyo, adding that he would likely resign to take responsibility, possibly after a shareholders’ meeting in June.

“Getting the nuclear plant under control, and the financial problems associated with that. How we can overcome these problems is a difficult matter.”

JapanÂ’s crisis has now been rated on par with the worldÂ’s worst nuclear accident at Chernobyl in 1986, although the total amount of radiation released is only a fraction of when the nuclear plant in Ukraine exploded.

TEPCO and the government have been under pressure to offer a road map for containing the crisis and to clarify when those who have had to evacuate the area around the damaged plant will be able to go home.

Prime Minister Naoto Kan has faced criticism over comments, which he later denied making, suggesting evacuees may not be able to return for 10 or 20 years.

After achieving a cold shutdown at the six-reactor plant, TEPCO said it would then focus on longer-term issues such as encasing the reactor buildings, cleaning up contaminated soil, and removing nuclear fuel to a safe holding place.

Two of the reactors are already in a stable state.

“I think it is doable, given the information TEPCO has released until now,” said a Japan-based university professor about the six to nine month time frame. The professor asked not to be quoted by name.

“But there are still so many issues that are unknown, and when you multiply the unknowns by four reactors, it is hard to say whether or not this is a realistic target.”

TEPCO has yet to determine how much it will have to pay residents and businesses uprooted by the crisis. The government has expanded a 20-km evacuation zone around the plant because of high-accumulated radiation.

JP Morgan has estimated TEPCO could face 2 trillion yen US $24 billion in compensation losses in the financial year that started this month, while Bank of America-Merrill Lynch has said the bill could reach $130 billion if the crisis continues.

The government is scrambling to come up with a scheme to limit the liability of TEPCO, which supplies roughly a third of JapanÂ’s electricity and whose failure would likely destabilize the financial markets.

TEPCO had $91 billion of debt on its books before the March crisis, and has since taken on a $24 billion bank loan. It is also the countryÂ’s largest corporate bond issuer and its shares are widely held by financial institutions.

Katsumata said TEPCO was considering selling assets and other restructuring steps to pay for compensation, but that it would need government help.

“We cannot answer anything about compensation until the government’s scheme is in place. No amount of asset sales would be enough if TEPCO were to shoulder all of the compensation,” he said.

“So we have been saying we want the government to decide the scheme immediately.”

The Nikkei newspaper reported earlier that TEPCO planned to sell shares in KDDI Corp. It holds about 360,000 shares in the telecoms firm, or an 8 per cent stake, which are worth about $2.2 billion at the current market price.

Katsumata did not comment specifically on its KDDI stake but said “we will do anything for rationalization, including asset sales and reduction in labour costs.”

New Hampshire rejects Quebec-Massachusetts transmission proposal

Northern Pass Project faces rejection by New Hampshire regulators, halting Hydro-Quebec clean energy transmission lines to Massachusetts; Eversource vows appeal as the Site Evaluation Committee cites development concerns and alternative routes through Vermont and Maine.

 

Key Points

A project to transmit Hydro-Quebec power to Massachusetts via New Hampshire, recently rejected by state regulators.

✅ New Hampshire SEC denied the transmission application

✅ Up to 9.45 TWh yearly from Hydro-Quebec to Massachusetts

✅ Eversource plans appeal; alternative routes via Vermont, Maine

 

Regulators in the state of New Hampshire on Thursday rejected a major electricity project being piloted by Quebec’s hydro utility and its American partner, Eversource.

Members of New Hampshire’s Site Evaluation Committee unanimously denied an application for the Northern Pass project a week after the state of Massachusetts green-lit the proposal.

Both states had to accept the project, as the transmission lines were to bring up to 9.45 terawatt hours of electricity per year from Quebec’s hydroelectric plants to Massachusetts as part of Hydro-Quebec’s export bid to New England, through New Hampshire.

The 20-year proposal was to be the biggest export contract in Hydro-Quebec’s history, in a region where Connecticut is leading a market overhaul that could affect pricing, and would generate up to $500 million in annual revenues for the provincial utility.

Hydro-Quebec’s U.S. partner, Eversource, said in a new release it was “shocked and outraged” by the New Hampshire regulators’ decision and suggested it would appeal.

“This decision sends a chilling message to any energy project contemplating development in the Granite State,” said Eversource. “We will be seeking reconsideration of the SEC’s decision, as well as reviewing all options for moving this critical clean energy project forward, including lessons from electricity corridor construction in Maine.”

The New Hampshire Union Leader reported Thursday the seven members of the evaluation committee said the project’s promoters couldn’t demonstrate the proposed energy transport lines wouldn’t interfere with the region’s orderly development.

Hydro-Quebec spokesman Serge Abergel said the decision wasn’t great news but it didn’t put a end to the negotiations between the company and the state of Massachusetts.

The hydro utility had proposed alternatives routes through Vermont and Maine amid a 145-mile transmission line debate over the corridor should the original plan fall through.

“There is a provision included in the process in the advent of an impasse, which allows Massachusetts to go back and choose the next candidate on the list,” Abergel said in an interview. “There are still cards left on the table.”

Greening Ontario's electricity grid would cost $400 billion: report

Ontario Electricity Grid Decarbonization outlines the IESO's net-zero pathway: $400B investment, nuclear expansion, renewables, hydrogen, storage, and demand management to double capacity by 2050 while initiating a 2027 natural gas moratorium.

 

Key Points

A 2050 plan to double capacity, retire gas, and invest $400B in nuclear, renewables, and storage for a net-zero grid.

✅ $400B over 25 years to meet net-zero electricity by 2050

✅ Capacity doubles to 88,000 MW; demand grows ~2% annually

✅ 2027 gas moratorium; build nuclear, renewables, storage

 

Ontario will need to spend $400 billion over the next 25 years in order to decarbonize the electricity grid and embrace clean power according to a new report by the province’s electricity system manager that’s now being considered by the Ford government.

The Independent System Electricity Operator (IESO) was tasked with laying out a path to reducing Ontario’s reliance on natural gas for electricity generation and what it would take to decarbonize the entire electricity grid by 2050.

Meeting the goal, the IESO concluded, will require an “aggressive” approach of doubling the electricity capacity in Ontario over the next two-and-a-half decades — from 42,000 MW to 88,000 MW — by investing in nuclear, hydrogen and wind and solar power while implementing conservation policies and managing demand.

“The process of fully eliminating emissions from the grid itself will be a significant and complex undertaking,” IESO president Lesley Gallinger said in a news release.

The road to decarbonization, the IESO said, begins with a moratorium on natural gas power generation starting in 2027 as long as the province has “sufficient, non-emitting supply” to meet the growing demands on the grid.

The approach, however, comes with significant risks.

The IESO said hydroelectric and nuclear facilities can take 10 to 15 years to build and if costs aren’t controlled the plan could drive up the price of clean electricity, turning homeowners and businesses away from electrification.

“Rapidly rising electricity costs could discourage electrification, stifle economic growth or hurt consumers with low incomes,” the report states.

The IESO said the province will need to take several “no regret” actions, including selecting sites and planning to construct new large-scale nuclear plants as well as hydroelectric and energy storage projects and expanding energy-efficiency programs beyond 2024.

Ontario’s minister of energy didn’t immediately commit to implementing the recommendations, citing the need to consult with stakeholders first.

“I look forward to launching a consultation in the new year on next steps from today’s report, including the potential development of major nuclear, hydroelectric and transmissions projects,” Todd Smith said in a statement.

Currently, electricity demand is increasing by roughly two per cent per year, raising concerns Ontario could be short of electricity in the coming years as the manufacturing and transportation sectors electrify and as more sectors consider decarbonization.

At the same time, the province’s energy supply is facing “downward pressure” with the Pickering nuclear power plant slated to wind down operations and the Darlington nuclear generating station under active refurbishment.

To meet the energy need, the Ford government said it intended to extend the life of the Pickering plant until 2026.

But to prepare for the increase, the Ontario government was told the province would also need to build new natural gas facilities to bridge Ontario’s electricity supply gap in the near term — a recommendation the Ford government agreed to.

The IESO said a request for proposals has been opened and the province is looking for host communities, with the expectation that existing facilities would be upgraded before projects on undeveloped land would be considered.

The IESO said the contract for any new facilities would expire in 2040, and all natural gas facilities would be retired in the 2040s.

How to Get Solar Power on a Rainy Day? Beam It From Space

Space solar power promises wireless energy from orbital solar satellites via microwave or laser power beaming, using photovoltaics and rectennas. NRL and AFRL advances hint at 24-7 renewable power delivery to Earth and airborne drones.

 

Key Points

Space solar power beams orbital solar energy to Earth via microwaves or lasers, enabling continuous wireless electricity.

✅ Harvests sunlight in orbit and transmits via microwaves or lasers

✅ Provides 24-7 renewable power, independent of weather or night

✅ Enables wireless power for remote sites, grids, and drones

 

Earlier this year, a small group of spectators gathered in David Taylor Model Basin, the Navy’s cavernous indoor wave pool in Maryland, to watch something they couldn’t see. At each end of the facility there was a 13-foot pole with a small cube perched on top. A powerful infrared laser beam shot out of one of the cubes, striking an array of photovoltaic cells inside the opposite cube. To the naked eye, however, it looked like a whole lot of nothing. The only evidence that anything was happening came from a small coffee maker nearby, which was churning out “laser lattes” using only the power generated by the system as ambitions for cheap abundant electricity gain momentum worldwide.

The laser setup managed to transmit 400 watts of power—enough for several small household appliances—through hundreds of meters of air without moving any mass. The Naval Research Lab, which ran the project, hopes to use the system to send power to drones during flight. But NRL electronics engineer Paul Jaffe has his sights set on an even more ambitious problem: beaming solar power to Earth from space. For decades the idea had been reserved for The Future, but a series of technological breakthroughs and a massive new government research program suggest that faraway day may have finally arrived as interest in space-based solar broadens across industry and government.

Since the idea for space solar power first cropped up in Isaac Asimov’s science fiction in the early 1940s, scientists and engineers have floated dozens of proposals to bring the concept to life, including inflatable solar arrays and robotic self-assembly. But the basic idea is always the same: A giant satellite in orbit harvests energy from the sun and converts it to microwaves or lasers for transmission to Earth, where it is converted into electricity. The sun never sets in space, so a space solar power system could supply renewable power to anywhere on the planet, day or night, as recent tests show we can generate electricity from the night sky as well, rain or shine.

Like fusion energy, space-based solar power seemed doomed to become a technology that was always 30 years away. Technical problems kept cropping up, cost estimates remained stratospheric, and as solar cells became cheaper and more efficient, and storage improved with cheap batteries, the case for space-based solar seemed to be shrinking.

That didn’t stop government research agencies from trying. In 1975, after partnering with the Department of Energy on a series of space solar power feasibility studies, NASA beamed 30 kilowatts of power over a mile using a giant microwave dish. Beamed energy is a crucial aspect of space solar power, but this test remains the most powerful demonstration of the technology to date. “The fact that it’s been almost 45 years since NASA’s demonstration, and it remains the high-water mark, speaks for itself,” Jaffe says. “Space solar wasn’t a national imperative, and so a lot of this technology didn’t meaningfully progress.”

John Mankins, a former physicist at NASA and director of Solar Space Technologies, witnessed how government bureaucracy killed space solar power development firsthand. In the late 1990s, Mankins authored a report for NASA that concluded it was again time to take space solar power seriously and led a project to do design studies on a satellite system. Despite some promising results, the agency ended up abandoning it.

In 2005, Mankins left NASA to work as a consultant, but he couldn’t shake the idea of space solar power. He did some modest space solar power experiments himself and even got a grant from NASA’s Innovative Advanced Concepts program in 2011. The result was SPS-ALPHA, which Mankins called “the first practical solar power satellite.” The idea, says Mankins, was “to build a large solar-powered satellite out of thousands of small pieces.” His modular design brought the cost of hardware down significantly, at least in principle.

Jaffe, who was just starting to work on hardware for space solar power at the Naval Research Lab, got excited about Mankins’ concept. At the time he was developing a “sandwich module” consisting of a small solar panel on one side and a microwave transmitter on the other. His electronic sandwich demonstrated all the elements of an actual space solar power system and, perhaps most important, it was modular. It could work beautifully with something like Mankins' concept, he figured. All they were missing was the financial support to bring the idea from the laboratory into space.

Jaffe invited Mankins to join a small team of researchers entering a Defense Department competition, in which they were planning to pitch a space solar power concept based on SPS-ALPHA. In 2016, the team presented the idea to top Defense officials and ended up winning four out of the seven award categories. Both Jaffe and Mankins described it as a crucial moment for reviving the US government’s interest in space solar power.

They might be right. In October, the Air Force Research Lab announced a $100 million program to develop hardware for a solar power satellite. It’s an important first step toward the first demonstration of space solar power in orbit, and Mankins says it could help solve what he sees as space solar power’s biggest problem: public perception. The technology has always seemed like a pie-in-the-sky idea, and the cost of setting up a solar array on Earth is plummeting, as proposals like a tenfold U.S. solar expansion signal rapid growth; but space solar power has unique benefits, chief among them the availability of solar energy around the clock regardless of the weather or time of day.

It can also provide renewable energy to remote locations, such as forward operating bases for the military, which has deployed its first floating solar array to bolster resilience. And at a time when wildfires have forced the utility PG&E to kill power for thousands of California residents on multiple occasions, having a way to provide renewable energy through the clouds and smoke doesn’t seem like such a bad idea. (Ironically enough, PG&E entered a first-of-its-kind agreement to buy space solar power from a company called Solaren back in 2009; the system was supposed to start operating in 2016 but never came to fruition.)

“If space solar power does work, it is hard to overstate what the geopolitical implications would be,” Jaffe says. “With GPS, we sort of take it for granted that no matter where we are on this planet, we can get precise navigation information. If the same thing could be done for energy, especially as peer-to-peer energy sharing matures, it would be revolutionary.”

Indeed, there seems to be an emerging race to become the first to harness this technology. Earlier this year China announced its intention to become the first country to build a solar power station in space, and for more than a decade Japan has considered the development of a space solar power station to be a national priority. Now that the US military has joined in with a $100 million hardware development program, it may only be a matter of time before there’s a solar farm in the solar system.

SC nuclear plant on the mend after a leak shut down production for weeks

V.C. Summer nuclear plant leak update: Dominion Energy repaired a valve in the reactor cooling system; radioactive water stayed within containment, NRC oversight continues as power output ramps toward full operation.

 

Key Points

A minor valve leak in the reactor cooling system contained onsite; Dominion repaired it as the plant resumes power.

✅ Valve leak in piping to steam generators, not environmental release.

✅ Radioactive water remained in containment, monitored per NRC rules.

✅ Plant ramping from 17% power; full operations may take days.

 

The V.C. Summer nuclear power plant, which has been shut down since early November because of a pipe leak, is expected to begin producing energy in a few days, a milestone comparable to a new U.S. reactor startup reported recently.

Dominion Energy says it has fixed the small leak in a pipe valve that allowed radioactive water to drip out. The company declined to say when the plant would be fully operational, but spokesman Ken Holt said that can take several days, amid broader discussions about the stakes of early nuclear closures across the industry.

The plant was at 17 percent power Wednesday, he said, as several global nuclear project milestones continue to be reported this year.

Holt, who said Dominion is still investigating the cause, said water that leaked was part of the reactor cooling system. While the water came in contact with nuclear fuel in the reactor, the water never escaped the plant's containment building and into the environment, Holt said.

He characterized the valve leak as '"uncommon" but not unexpected. The nuclear leak occurred in piping that links the nuclear reactor with the power plant's steam generators. Hundreds of pipes are in that part of the nuclear plant, a complexity often cited in the energy debate over struggling nuclear plants nationwide.

"There is always some level of leakage when you are operating, but it is contained and monitored, and when it rises to a certain level, you may take action to stop it," Holt said.

A nuclear safety watchdog has criticized Dominion for not issuing a public notice about the leak, but both the company and the U.S. Nuclear Regulatory Commission say the amount was so small it did not require notice.

The V.C. Summer Nuclear plant is about 25 miles northwest of Columbia in Fairfield County. It was licensed in the early 1980s. At one point, Dominion's predecessor, SCE&G, partnered with state owned Santee Cooper to build two more reactors there, even as new reactors in Georgia were taking shape. But the companies walked away from the project in 2017, citing high costs and troubles with its chief contractor, Westinghouse, even as closures such as Three Mile Island's shutdown continued to influence policy.

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.”

BC Hydro electricity demand down 10% amid COVID-19 pandemic

BC Hydro electricity demand decline reflects COVID-19 impacts across British Columbia, with reduced industrial load, full reservoirs, strategic spilling, and potential rate increases, as hydropower plants adjust operations at Seven Mile, Revelstoke, and Site C.

 

Key Points

A 10% COVID-19-driven drop in BC power use, prompting reservoir spilling, plant curtailment, and potential rate hikes.

✅ 10% load drop; industrial demand down 7% since mid-March

✅ Reservoirs near capacity; controlled spilling to mitigate risk

✅ Possible rate hikes; Site C construction continues

 

Elecricity demand is down 10 per cent across British Columbia, an unprecedented decline in commercial electricity consumption sparked by the COVID-19 pandemic, according to a BC Hydro report.

Power demand across hotels, offices, recreational facilities and restaurants have dwindled as British Columbians self isolate, and bill relief for residents and businesses was introduced during this period.

The shortfall means there's a surplus of water in reservoirs across the province.

"This drop in load in addition to the spring snow melt is causing our reservoirs to reach near capacity, which could lead to environmental concerns, as well as public safety risks if we don't address the challenges now," said spokesperson Tanya Fish.

Crews will have to strategically spill reservoirs to keep them from overflowing, a process that can have negative impacts on downstream ecosystems. Excessive spilling can increase fish mortality rates.

Spilling is currently underway at the Seven Mile and Revelstoke reservoirs. In addition, several small plants have been shut down.

Site C and hydro rates
According to the report, titled Demand Dilemma, the decline could continue into April 2021 and drop by another two per cent, even as a regulator report alleged BC Hydro misled oversight bodies.

Major industry — forestry, mining and oil and gas — accounts for about 30 per cent of BC Hydro's overall electricity load. Energy demand from these customers has dropped by seven per cent since mid-March, while in Manitoba a Consumers Coalition has urged rejection of proposed rate increases.

BC Hydro says a prolonged drop in demand could have an impact on future rates, which could potentially go up as the power provider looks to recoup deferred operating costs and financial losses.

In Manitoba, Manitoba Hydro's debt has grown significantly, underscoring the financial risks utilities face during demand shocks.

Fish said the crown corporation still expects there to be increased demand in the long-term. She said construction of the Site C Dam is continuing as planned to support clean-energy generation in the province. There are currently nearly 1,000 workers on-site.
