New York Independent System Operator, the nonprofit that oversees the state's wholesale electric markets, is moving to allow flywheel and battery technologies to be connected to the grid.

The addition would mean a 20-megawatt flywheel project being built in Stephentown, Rensselaer County, could be used to help meet the state's energy needs.

Flywheels are mechanical batteries that use kinetic energy to store electricity from the grid that otherwise would be wasted. When the energy is needed, the systems can send it back onto the grid.

Although the flywheel concept is ancient, today's flywheel technology uses heavy wheels that spin at more than 20,000 revolutions per minute from power drawn from the grid.

The spinning wheels, which are in cylinders inside an enclosed facility, act as generators that can supply electricity back to the grid when needed.

Such on-demand electricity supply is called "regulation" service that balances variances in supply and demand on the grid.

NYISO spokesman Ken Klapp said most regulation service is done today by fossil-fuel plants. But flywheel and other technologies could also provide that electricity with a renewable and nonpolluting process.

"You're really relying on fossil-fuel units for doing this," Klapp said.

Stephen Whitley, president of the East Greenbush-based NYISO, has been pushing renewable-energy technologies to help share production for the state's electric grid. He has been encouraging wind especially, and now wants to introduce these new technologies, which are called limited-energy storage resources.

"These new resources are ideal for responding to the moment-to-moment adjustments needed to operate the bulk electricity grid," Whitley said in a statement.

NYISO filed a new set of rules and regulations, known as a tariff, with the Federal Energy Regulatory Commission on March 19 to allow flywheels and other technologies to provide such regulation service. The agency hope to have the approval in place by mid-May.

The company developing the project in Stephentown, Beacon Power Corp. of Tyngsboro, Mass., did not return a call seeking comment on the status of the facility. The company reported to investors earlier this month that it has received all the permits it needs for the project.

U.S. Speeds Up Permitting for Geothermal Energy

Geothermal Emergency Permitting accelerates BLM approvals on public lands via categorical exclusions for exploratory drilling and geophysical surveys, boosting domestic energy security, cutting timelines by up to a year, and streamlining low-impact reviews.

 

Key Points

A policy fast-tracking geothermal exploration on public lands, using BLM categorical exclusions to cut review delays.

✅ Categorical exclusions speed exploratory drilling approvals

✅ Cuts permitting timelines by up to one year

✅ Focused on public lands to enhance energy security

 

In a significant policy shift, the U.S. Department of the Interior has introduced emergency permitting procedures aimed at expediting the development of geothermal energy projects. This initiative, announced on May 30, 2025, is part of a broader strategy to enhance domestic energy production, seen in proposals to replace Obama's power plant overhaul and reduce reliance on foreign energy sources.

Background and Rationale

The decision to fast-track geothermal energy projects comes in the wake of President Donald Trump's declaration of a national energy emergency, which faces a legal challenge from Washington's attorney general, on January 20, 2025. This declaration cited high energy costs and an unreliable energy grid as threats to national security and economic prosperity. While the emergency order includes traditional energy resources such as oil, gas, coal, and uranium and nuclear energy resources, it notably excludes renewable sources like solar, wind, and hydrogen from its scope.

Geothermal energy, which harnesses heat from beneath the Earth's surface to generate electricity, is considered a reliable and low-emission energy source. However, its development has been hindered by lengthy permitting processes and environmental reviews, with recent NEPA rule changes influencing timelines. The new emergency permitting procedures aim to address these challenges by streamlining the approval process for geothermal projects.

Key Features of the Emergency Permitting Procedures

Under the new guidelines, the Bureau of Land Management (BLM) has adopted categorical exclusions to expedite the review and approval of geothermal energy exploration on public lands. These exclusions allow for faster permitting of low-impact activities, such as drilling exploratory wells and conducting geophysical surveys, without the need for extensive environmental assessments.

Additionally, the BLM has proposed a new categorical exclusion that would apply to operations related to the search for indirect evidence of geothermal resources. This proposal is currently open for public comment and, if finalized, would further accelerate the discovery of new geothermal resources on public lands.

Expected Impact on Geothermal Energy Development

The implementation of these emergency permitting procedures is expected to significantly reduce the time and cost associated with developing geothermal energy projects. According to the Department of the Interior, the new measures could cut permitting timelines by up to a year for certain types of geothermal exploration activities.

This acceleration in project development is particularly important given the untapped geothermal potential in regions like Nevada, which is home to some of the largest undeveloped geothermal resources in the country.

Industry and Environmental Reactions

The geothermal industry has largely welcomed the new permitting procedures, viewing them as a necessary step to unlock the full potential of geothermal energy. Industry advocates argue that reducing permitting delays will facilitate the deployment of geothermal projects, contributing to a more reliable and sustainable energy grid amid debates over electricity pricing changes that affect market signals.

However, the exclusion of solar and wind energy projects from the emergency permitting procedures has drawn criticism from some environmental groups. Critics argue that a comprehensive approach to energy development should include all renewable sources, not just geothermal, to effectively address climate change, as reflected in new EPA pollution limits for coal and gas power plants, and promote energy sustainability.

The U.S. government's move to implement emergency permitting procedures for geothermal energy development marks a significant step toward enhancing domestic energy production and reducing reliance on foreign energy sources. By streamlining the approval process for geothermal projects, the administration aims to accelerate the deployment of this reliable and low-emission energy source. While the exclusion of other renewable energy sources from the emergency procedures has sparked debate, especially after states like California halted an energy rebate program during a federal freeze, the focus on geothermal energy underscores its potential role in the nation's energy future.

Time running out for Ontario to formally request Pickering nuclear power station extension

Pickering Nuclear Plant Extension faces CNSC approval as Ontario Power Generation pursues license renewal before the June 30, 2023 deadline, amid a 2025 capacity crunch and grid reliability risks from decommissioning and overlapping nuclear outages.

 

Key Points

A plan to run Pickering past 2024 to Sept 2026, pending CNSC license renewal to address Ontario's 2025 capacity gap.

✅ CNSC approval needed for operation beyond Dec 31, 2024

✅ OPG aims to file by June 30, 2023 deadline

✅ Extension targets grid reliability through 2026

 

Ontario’s electricity generator has yet to file an official application to extend the life of the Pickering nuclear power plant, more than eight months after the Ford government announced a plan to continue operating Pickering for longer.

As the province faces an electricity shortfall in 2025 and beyond, the Ford government scrambled to prolong the Pickering power plant until September 2026, in order to guarantee a steady supply of power as the province experiences a rise in demand and shutdowns at other nuclear power plants.

The life extension may come down to the wire, however, as the Canadian Nuclear Safety Commission (CNSC), the federal regulator tasked with approving or denying the extension, tells Global News the province has yet to file key paperwork.

The information is required for the application, including materials related to the proposed Pickering B refurbishment, and the government now has a month before the deadline runs out.

“The Commission requires that Ontario Power Generation submit specific information by June 30, 2023, if it intends to operate the Pickering Nuclear Generating Station beyond December 31, 2024,” the CNSC told Global News in a statement. “The Commission Registry has not yet received an application from Ontario Power Generation.”

If Ontario doesn’t receive the green light, the power plant which currently is responsible for 14 per cent of the province’s energy grid will be decommissioned in 2025, leaving the province with a significant electricity supply gap if replacement sources are not secured.

For its part, the Ford government doesn’t seem concerned about the impending timeline, even though the station was slated to close as planned, suggesting the Crown corporation responsible for the application will get it in on time.

“OPG is on track to submit their application before the end of June and has already started to submit supporting materials as part of the regulatory process toward clean power goals,” a spokesperson for energy minister Todd Smith said.

Investor: Hydro One has too many unknowns to be a good investment

Hydro One investment risk reflects Ontario government influence, board shakeup, Avista acquisition uncertainty, regulatory hearings, dividend growth prospects, and utility M&A moves in Peterborough, with stock volatility since the 2015 IPO.

 

Key Points

Hydro One investment risk stems from political control, governance turnover, regulatory outcomes, and uncertain M&A.

✅ Ontario retains near-50% stake, affecting autonomy and policy risk

✅ Board overhaul and CEO exit create governance uncertainty

✅ Avista deal, OEB hearings, local utility M&A drive outcomes

 

Hydro One may be only half-owned by the province on Ontario but that’s enough to cause uncertainty about the company’s future, thus making for an investment risk, says Douglas Kee of Leon Frazer & Associates.

Since its IPO in November of 2015, Hydro One has seen its share of ups and downs, including a Q2 profit decline earlier this year, mostly downs at this point. Currently trading at $19.87, the stock has lost 11 per cent of its value in 2018 and 12 per cent over the last 12 months, despite a one-time gain boosting Q2 profit that followed a court ruling.

This year has been a turbulent one, to say the least, as newly elected Ontario premier Doug Ford made good this summer on his campaign promise re Hydro One by forcing the resignation of the company’s 14-person board of directors along with the retirement of its chief executive, an event that saw Hydro One shares fall amid the turmoil. An interim CEO has been found and a new 10-person board and chairman put in place, but Kee says it’s unclear what impact the shakeup will ultimately have, other than delaying a promising-looking deal to purchase US utility Avista Corp, with the companies moving to ask the U.S. regulator to reconsider the order.

 

Douglas Kee’s take on Hydro One stock

“We looked at Hydro One a couple of times two years ago and just decided that with the Ontario government’s still owning a big chunk of the company … there are other public companies where you get the same kind of yield, the same kind of dividend growth, so we just avoided it,” says Kee, managing director and chief investment officer with Leon Frazer & Associates, to BNN Bloomberg.

“The old board versus the new board, I’m not sure that there’s much of an improvement. It was politics more than anything,” he says. “The unfortunate part is that the acquisition they were making in the United States is kind of on hold for now. The regulatory procedures have gone ahead but they are worried, and I guess the new board has to make a decision whether to go ahead with it or not.”

“Their transmissions side is coming up for regulatory hearings next year, which could be difficult in Ontario,” says Kee. “The offset to that is that there are a lot of municipal distributions systems in Ontario that may be sold — they bought one in Peterborough recently, which was a good deal for them. There may be more of that coming too.”

Last month, Hydro One reached an agreement with the City of Peterborough to buy its Peterborough Distribution utility which serves about 37,000 customers for $105 million. Another deal to purchase Orillia Power Distribution Corp for $41 million has been cancelled after an appeal to the Ontario Energy Board was denied in late August. Hydro One’s sought-after Avista Corp acquisition is reported to be worth $7 billion.

Seattle Apartment Fire Caused by Overheated Power Strip

Seattle Capitol Hill Apartment Fire highlights an electrical fire from an overheated power strip, a two-alarm response by 70 firefighters, safe evacuation, displaced resident aid, and prevention tips like smoke detectors and load limits.

 

Key Points

Two-alarm early-morning blaze in Seattle traced to an overheated power strip, displacing one resident and injuring none.

✅ Origin: overheated power strip ignited nearby combustibles

✅ Response: 70 firefighters, two-alarm, rapid containment

✅ Safety: avoid overloads; inspect cords; use smoke detectors

 

An early-morning fire in Seattle’s Capitol Hill neighborhood severely damaged a three-story apartment building, displacing one resident. The blaze, which broke out around 4:34 a.m. on a Friday, drew more than 70 firefighters to the scene, as other critical sectors have implemented on-site staffing during outbreaks to maintain operations, and was later traced to an overheated power strip.

The Fire Incident

The Seattle Fire Department responded to the fire, which had started on the second floor of the building in the 1800 block of 12th Avenue. Upon arrival, crews were met with heavy smoke and flames coming from one unit. The fire quickly spread to a unit on the third floor, prompting the Seattle Fire Department to escalate their response to a two-alarm fire due to its size and the potential threat to nearby structures.

Firefighters initially attempted to contain the blaze from the exterior before they moved inside the building to fully extinguish the fire. Thankfully, the fire was contained to the two affected units, preventing the destruction of the remaining seven apartments in the building.

All residents safely evacuated the building on their own. Despite the substantial damage to the two apartments, no injuries were reported. One resident was displaced by the fire and was assisted by the Red Cross in finding temporary accommodation.

Cause of the Fire

Investigators later determined that the fire was accidental, most likely caused by an overheated electrical power strip. The power strip had reportedly ignited nearby combustible materials, sparking the flames that quickly spread throughout the unit. Although the exact details are still under investigation, the fire serves as a stark reminder of the potential risks associated with overloaded or damaged electrical equipment and how electrical safety knowledge gaps can contribute to incidents.

The Risks of Power Strips

Power strips, while essential for providing multiple outlets, can pose a serious fire hazard if used improperly, and specialized arc flash training in Vancouver underscores the importance of understanding electrical hazards across settings.

This fire in Seattle highlights the importance of maintaining electrical devices and following proper usage guidelines. According to experts, it is crucial to regularly inspect power strips for any visible damage, such as frayed cords or scorch marks, and to replace them if necessary. It's also advisable to avoid using power strips with high-power appliances like space heaters, microwaves, or refrigerators.

Impact and Community Response

The fire has raised awareness about the dangers of electrical hazards in residential buildings, especially in older apartment complexes where wiring systems may not be up to modern standards. Local authorities and fire safety experts are urging residents to review safety guidelines and ensure that their living spaces are free from potential fire hazards and to avoid dangerous stunts at dams and towers that can lead to serious injuries.

Seattle's fire department, which responded to this incident, continues to emphasize fire prevention and safety education. This event also highlights the importance of having working smoke detectors and clear escape routes in apartment buildings, and ongoing fire alarm training can improve system reliability. The Seattle Fire Department recommends that all tenants know the locations of fire exits and practice safe evacuation procedures, especially in high-rise or multi-unit buildings.

Additionally, the Red Cross has stepped in to assist the displaced resident. The organization provides temporary shelter, food, and financial aid for those affected by disasters like fires. The fire underscores the importance of having emergency preparedness plans in place and the need for immediate relief for those who lose their homes in such incidents.

The Seattle apartment fire, which displaced one resident and caused significant damage to two units, serves as a reminder of the potential dangers associated with improperly maintained or overloaded electrical devices, especially power strips, and how industry recognition, such as a utility safety award, reinforces best practices. While the cause of this fire was linked to an overheated power strip, it could have easily been prevented with regular inspections and safer practices.

As fire departments continue to respond to similar incidents, it is critical for residents to stay informed about fire safety, particularly regarding electrical equipment and outdoor hazards like safety near downed power lines in storm conditions. Awareness, proper maintenance, and following safety protocols can significantly reduce the risk of electrical fires and help protect residents from harm.

Renewable energy now cheapest option for new electricity in most of the world: Report

Renewable Energy Cost Trends highlight IRENA data showing solar and wind undercut coal, as utility-scale projects drive lower levelized electricity costs worldwide, with the Middle East and UAE advancing mega solar parks.

 

Key Points

They track how solar and wind undercut new fossil fuels as utility-scale costs drop and investment accelerates.

✅ IRENA reports renewables cheapest for new installations

✅ Solar and wind LCOE fell sharply since 2010

✅ Middle East and UAE scale mega utility projects

 

Renewable energy is now the cheapest option for new electricity installation in most of the world, a report from the International Renewable Energy Agency (IRENA) on Tuesday said.

Renewable power projects have undercut traditional coal fuel plants, with solar and wind power costs in particular falling as record-breaking growth continues worldwide.

“Installing new renewables increasingly costs less than the cheapest fossil fuels. With or without the health and economic crisis, dirty coal plants were overdue to be consigned to the past, said Francesco La Camera, director-general of IRENA said in the report.

In 2019, renewables accounted for around 72 percent of all new capacity added worldwide, IRENA said, following a 2016 record year that highlighted the momentum, with lowering costs and technological improvements in solar and wind power helping this dynamic. For solar energy, IRENA notes that the cost for electricity from utility-scale plants fell by 82 percent in the decade between 2010 and 2019, as China's solar PV growth underscored in 2016.

“More than half of the renewable capacity added in 2019 achieved lower electricity costs than new coal, while new solar and wind projects are also undercutting the cheapest and least sustainable of existing coal-fired plants,” Camera added.

Costs for solar and wind power also fell year-on-year by 13 and 9 percent, respectively, with offshore wind costs showing steep declines as well. In 2019, more than half of all newly commissioned utility-scale renewable power plants provided electricity cheaper than the lowest cost of a new fossil fuel plant.

The Middle East

In mid-May, a report by UK-based law firm Ashurst suggested the Middle East is the second most popular region for renewable energy investment after North America, at a time when clean energy investment is outpacing fossil fuels.

The region is home to some of the largest renewable energy bets in the world, with Saudi wind expansion gathering pace. The UAE, for instance, is currently developing the Mohammed Bin Rashid Solar Park, the world’s largest concentrated solar power project in the world.

Around 26 percent of Middle East respondents in Ashurst’s survey said that they were presently investing in energy transition, marking the region as the most popular for current investment in renewables, while 11 percent added that they were considering investing.

In North America, the most popular region, 28 percent said that they were currently investing, with 11 percent stating they are considering investing.

Maritime Link sends first electricity between Newfoundland, Nova Scotia

Maritime Link HVDC Transmission connects Newfoundland and Nova Scotia to the North American grid, enabling renewable energy imports, subsea cable interconnection, Muskrat Falls hydro power delivery, and lower carbon emissions across Atlantic Canada.

 

Key Points

A 500 MW HVDC intertie linking Newfoundland and Nova Scotia to deliver Muskrat Falls hydro power.

✅ 500 MW capacity using twin 170 km subsea HVDC cables

✅ Interconnects Newfoundland and Nova Scotia to the North American grid

✅ Enables Muskrat Falls hydro imports, cutting CO2 and costs

 

For the first time, electricity has been sent between Newfoundland and Nova Scotia through the new Maritime Link.

The 500-megawatt transmission line — which connects Newfoundland to the North American energy grid for the first time and echoes projects like the New England Clean Power Link underway — was tested Friday.

"This changes not only the energy options for Newfoundland and Labrador but also for Nova Scotia and Atlantic Canada," said Rick Janega, the CEO of Emera Newfoundland and Labrador, which owns the link.

"It's an historic event in our eyes, one that transforms the electricity system in our region forever."

 

'On time and on budget'

It will eventually carry power from the Muskrat Falls hydro project in Labrador, where construction is running two years behind schedule and $4 billion over budget, a context in which the Manitoba Hydro line to Minnesota has also faced delay, to Nova Scotia consumers. It was supposed to start producing power later this year, but the new deadline is 2020 at the earliest.

The project includes two 170-kilometre subsea cables across the Cabot Strait between Cape Ray in southwestern Newfoundland and Point Aconi in Cape Breton.

The two cables, each the width of a two-litre pop bottle, can carry 250 megawatts of high voltage direct current, and rest on the ocean floor at depths up to 470 metres.

The Maritime Link also includes almost 50 kilometres of overland transmission in Nova Scotia and more than 300 kilometres of overland transmission in Newfoundland, paralleling milestones on Site C transmission work in British Columbia.

The link won't go into commercial operation until January 1.

Janega said the $1.6-billion project is on time and on budget.

"We're very pleased to be in a position to be able to say that after seven years of working on this. It's quite an accomplishment," he said.

Once in service, the link will improve electrical interconnections between the Atlantic provinces, aligning with climate adaptation guidance for Canadian utilities.

"For Nova Scotia it will allow it to achieve its 40 per cent renewable energy target in 2020. For Newfoundland it will allow them to shut off the Holyrood generating station, in fact using the Maritime Link in advance of the balance of the project coming into service," Janega said.

Karen Hutt, president and CEO of Nova Scotia Power, which is owned by Emera Inc., calls it a great day for Nova Scotia.

"When it goes into operation in January, the Maritime Link will benefit Nova Scotia Power customers by creating a more stable and secure system, helping reduce carbon emissions, and enabling NSP to purchase power from new sources," Hutt said in a statement.
