A wind farm on Minnesota's Iron Range was fully online this summer, but seven of the 10 wind turbines have been shut off in recent months for repairs.

For that reason, Taconite Ridge wind farm isn't producing as much electricity as Minnesota Power anticipated.

The $50 million project overlooks U.S. Steel's Minntac mine and covers about 450 acres.

This fall, inspectors with the turbine manufacturer discovered defects in several of the turbines' blades, and repairs have taken longer than anticipated, said Amy Rutledge, a spokeswoman for Minnesota Power.

"We had hoped they would be wrapped up by mid-December, but we've had a few issues with the weather," Rutledge said. Windy weather prevented the manufacturer from removing the rotors as quickly as they'd have liked, she said.

Repair crews for manufacturer Clipper Windpower hope all 10 turbines will be working by the end of January, Rutledge said. The delay won't affect Minnesota Power's electrical supply.

The defects, which aren't considered structural, are "wrinkles" in the fiberglass blades that must be fixed, said Taconite Ridge project manager Andrew Remus.

"If we leave them the way they are, without taking any action, they will affect the way the blade operates," Remus said. "The blade is all one piece, and you need it to be perfect."

Some of the blade wrinkles will be sanded down and re-laminated, Rutledge said. Others will get a patch — a repair similar to using putty to repair a dented car, she said.

Taconite Ridge is the first large-scale wind farm in northern Minnesota. At full capacity, the turbines could produce 25 megawatts of electricity, which is enough to power 8,000 homes.

Minnesota Power is using the wind farm to increase its renewable energy resources and meet the requirements of a new state mandate for electrical utilities to produce 25 percent of their electricity from renewable sources by 2025.

Nuclear plant workers cite lack of precautions around virus

Millstone COVID-19 safety concerns center on a nuclear refueling outage in Connecticut, temporary workers, OSHA complaints, PPE shortages, and disinfecting protocols, as Dominion Energy addresses virus precautions, staffing, and cybersecurity for safe voting infrastructure.

 

Key Points

Employee and union claims about PPE, cleaning, and OSHA compliance during a refueling outage at the nuclear plant.

✅ 10 positive cases; 750 temporary workers during refueling outage

✅ Union cites PPE gaps, partitions, and disinfectant effectiveness

✅ Dominion Energy notes increased cleaning, communication, staffing

 

Workers at Connecticut's only nuclear power plant worry that managers are not taking enough precautions against the coronavirus, as some utilities weigh on-site staffing measures to maintain operations, after 750 temporary employees were brought in to help refuel one of the two active reactors.

Ten employees at the Millstone Power Station in Waterford have tested positive for the virus, and, amid a U.S. grid pandemic warning, the arrival of the temporary workers alarms some of the permanent employees, The Day newspaper reported Sunday.

"Speaking specifically for the guard force, there's a lot of frustration, there's a lot of concern, and I would say there's anger," said Millstone security officer Jim Foley.

Foley, vice president of the local chapter of the United Government Security Officers of America, noted broader labor concerns such as unpaid wages for Kentucky miners while saying security personnel have had to fight for personal protective equipment and for partitions at access points to separate staff from security.

Foley also has filed a complaint with the Occupational Safety and Health Administration saying Millstone staff are using ineffective cleaning materials and citing a lack of cleaning and sanitizing, as telework limits at the EPA drew scrutiny during the pandemic, he said.

Officials at Millstone, owned by Dominion Energy, have not heard internal criticism about the plant's virus precautions, Millstone spokesman Kenneth Holt said.

"We've actually gotten a lot of compliments from employees on the steps we've taken," he said. "We've stepped up communications with employees to let them know what's going on."

As another example of communication efforts, COVID-19 updates at Site C have been published to keep workers informed.

Millstone recently increased cleaning staff on the weekends, Holt said, and there is regular disinfecting at the plant.

Separately, utility resilience remains a concern, as extended outages for tornado survivors in Kentucky may last weeks, affecting essential services.

Responding to the complaint about ineffective cleaning materials, Holt said staff members early in the pandemic went to a Home Depot and got a bottle of disinfectant that wasn't approved by the federal government as effective against the coronavirus. An approved disinfectant was brought in the next day, he said.

The deaths of nearly 2,500 Connecticut residents have been linked to COVID-19, the disease caused by the virus. More than 29,000 state residents have tested positive. As of Sunday, hospitalizations had declined for 11 consecutive days, to over 1,480.

With more people working remotely, utilities have reported higher residential electricity use during the pandemic, affecting household bills.

For most people, the coronavirus causes mild or moderate symptoms, such as fever and cough, that clear up in two to three weeks. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia, and death.

In other developments related to the coronavirus:

SAFE VOTING

Secretary of the State Denise Merrill released a plan Monday aimed at making voting safe during the Aug. 11 primary and Nov. 3 general election.

Merrill said her office is requiring all cities and towns in the state to submit plans for the two elections that include a list of cleaning and safety products to be used, a list of polling locations, staffing levels at each polling location, and the names of polling workers and moderators.

Municipalities will be eligible for grants to cover the extra costs of holding elections during a pandemic, including expenses for cleaning products and increased staffing.

Merrill also announced her office and the Connecticut National Guard will perform a high-level cybersecurity assessment of the election infrastructure of all 169 towns in the state to guard against malicious actors.

Merrill's office also will provide network upgrades to the election infrastructures of 20 towns that have had chronic problems with connecting to the elections system.

Electric vehicles are a hot topic in southern Alberta

Canada Electric Vehicle Adoption is accelerating as EV range doubles, fast-charging networks expand along the Trans-Canada Highway, and drivers shift from internal combustion to clean transportation to cut emissions and support climate goals.

 

Key Points

Canada Electric Vehicle Adoption reflects rising EV uptake, longer range, and expanding fast-charging infrastructure.

✅ Average EV range in Canada has nearly doubled in six years.

✅ Fast chargers expanding along Trans-Canada and major corridors.

✅ Gasoline and diesel demand projected to fall sharply by 2040.

 

As green technology for vehicles continues to grow in popularity, with a recent EV event in Regina drawing strong interest, attendance at a seminar in southern Alberta Wednesday showed plenty people want to switch to electric.

FreeU, a series of informal education sessions about electric power and climate change, including electricity vs hydrogen considerations, helped participants to learn more about the world-changing technology.

Also included at the talks was a special electric vehicle meet up, where people interested in the technology could learn about it, first hand, from drivers who've already gone gasless despite EV shortages and wait times in many regions.

"That's kind of a warning or a caution or whatever you want to call it. You get addicted to these things and that's a good example."

James Byrne, a professor of geography at the University of Lethbridge says people are much more willing these days to look to alternatives for their driving needs, though cost remains a key barrier for many.

"The internal combustion engine is on its way out. It served us well, but electric vehicles are much cleaner, aligning with Canada's EV goals set by policymakers today."

According to the Canada Energy Regulator, the average range of electric vehicles in Canada have almost doubled in the past six years.

The agency also predicts a massive decrease in gasoline and diesel use (359 petajoules and 92 petajoules respectively) in Canada by 2040. In that same timeframe, electricity use, even though fossil-fuel share remains, is expected to increase by 118 petajoules.

The country is also developing its network of fast charging stations, so running out of juice will be less of a worry for prospective buyers, even as 2035 EV mandate debate continues among analysts.

"They have just about Interstate in the U.S. covered," Marshall said. "In Canada, they're building out the [Trans-Canada Highway] right now."

Electricity exports to New York from Quebec will happen as early as 2025: Hydro-Quebec

Hertel-New York Interconnection delivers Hydro-Quebec renewable energy via a cross-border transmission line to New York City by 2025, supplying 1,250 MW through underground and underwater routes under a 25-year contract.

 

Key Points

A cross-border line delivering 1,250 MW of Hydro-Quebec hydropower to New York City via underground routes.

✅ 1,250 MW clean power to NYC by 2025

✅ 56.1 km underground, 1.6 km underwater in Quebec

✅ 25-year contract; Mohawk partnership revenue

 

Hydro-Quebec announced Thursday it has chosen the route for the Hertel-New York interconnection line, which will begin construction in the spring of 2023 in Quebec.

The project will deliver 1,250 megawatts of Quebec hydroelectricity to New York City starting in 2025, even as a recent electricity shortage report warns about rising demand at home.

It's a 25-year contract for Hydro-Quebec, the largest export contract for the province-owned company, and comes as hydrogen production investments gain traction in Eastern Canada.

The Crown corporation has not disclosed potential revenues from the project, but Premier François Legault mentioned on social media last September that a deal in principle worth more than $20 billion over 25 years was in the works.

The route includes a 56.1-kilometre underground and a 1.6-kilometre underwater section, similar to the Lake Erie Connector project planned under Lake Erie.

Eight municipalities in the Montérégie region will be affected: La Prairie, Saint-Philippe, Saint-Jacques-le-Mineur, Saint-Édouard, Saint-Patrice-de-Sherrington, Saint-Cyprien-de-Napierville, Saint-Bernard-de-Lacolle and Lacolle.

Across the country, new renewables such as wind projects in Yukon are receiving federal support, reflecting broader grid decarbonization.

The last part of the route will run along Fairbanks Creek to the Richelieu River, where it will connect with the American network.

Further south, there will be a 545-kilometre link between the Canada-U.S. border and New York City, while a separate Maine transmission approval advances a New England pathway for Quebec power.

Hydro-Quebec is holding two consultations on the project, on Dec. 8 in Lacolle and Dec. 9 in Saint-Jacques-le-Mineur.

Elsewhere in Atlantic Canada, EV-to-grid integration pilots are underway to test how vehicles can support the power system.

Once the route is in service, the Quebec line will be subject to a partnership between Hydro-Quebec and the Mohawk Council of Kahnawake, which will benefit from economic remunerations for 40 years.

To enhance reliability, grid-scale battery storage projects are also expanding in Ontario.

U.S. Residents Averaged Fewer Power Outages in 2022

2022 U.S. Power Outage Statistics show lower SAIDI as fewer major events hit, with SAIFI trends, electric reliability, outage duration and frequency shaped by hurricanes, winter storms, vegetation, and utility practices across states.

 

Key Points

They report SAIDI and SAIFI for 2022, showing outage duration, frequency, and impacts of major weather events.

✅ 2022 SAIDI averaged 5.6 hours; SAIFI averaged 1.4 interruptions.

✅ Fewer major events lowered outage duration versus 2021.

✅ Hurricanes and winter storms drove long outages in several states.

 

In 2022, U.S. electricity consumers on average experienced about 5.5 hours of power disruptions, a decrease from nearly two hours compared to 2021. This information comes from the latest Annual Electric Power Industry Report. The reduction in yearly power interruptions primarily resulted from fewer significant events in 2022 compared to the previous year, and utility disaster planning continues to support grid resilience as severe weather persists.

Since 2013, excluding major events, the annual average duration of power interruptions has consistently hovered around two hours. Factors contributing to major power disruptions include weather-related incidents, vegetation interference near power lines, and specific utility practices, while pandemic-related grid operations influenced workforce planning more than outage frequency. To assess the reliability of U.S. electric utilities, two key indexes are utilized:

  • The System Average Interruption Duration Index (SAIDI) calculates the total length (in hours) an average customer endures non-brief power interruptions over a year.
  • The System Average Interruption Frequency Index (SAIFI) tracks the number of times interruptions occur.

The influence of major events on electrical reliability is gauged by comparing affected states' SAIDI and SAIFI values against the U.S. average, which was 5.6 hours of outages and 1.4 outages per customer in 2022. The year witnessed 18 weather-related disasters in the U.S., each resulting in over $1 billion in damages, and COVID-19 grid assessments indicated the electricity system was largely safe from pandemic impacts. Noteworthy major events include:

  • Hurricane Ian in September 2022, leaving over 2.6 million Floridian customers without electricity, with restoration in some areas taking weeks rather than days.
  • Hurricane Nicole in November 2022, causing over 300,000 Florida customers to lose power.
  • Winter Storm Elliott in December 2022, affecting over 1.5 million customers in multiple states including Texas where utilities struggled after Hurricane Harvey to restore service, and Florida, and bringing up to four feet of snow in parts of New York.

In 2022, states like Florida, West Virginia, Maine, Vermont, and New Hampshire experienced the most prolonged power interruptions, with New Hampshire averaging 10.3 hours and Florida 19.1 hours, and FPL's Irma storm response illustrates how restoration can take days or weeks in severe cases. Conversely, the District of Columbia, Delaware, Rhode Island, Nebraska, and Iowa had the shortest total interruptions, with the District of Columbia averaging just 34 minutes and Iowa 85 minutes.

The frequency of outages, unlike their duration, is more often linked to non-major events. Across the nation, Alaska recorded the highest number of power disruptions per customer (averaging 3.5), followed by several heavily forested states like Tennessee and Maine. Power outages due to falling tree branches are common, particularly during winter storms that burden tree limbs and power lines, as seen in a North Seattle outage affecting 13,000 customers. The District of Columbia stood out with the shortest and fewest outages per customer.

Nova Scotia's last paper mill seeks new discount electricity rate

Nova Scotia Power Active Demand Control Tariff lets the utility direct Port Hawkesbury Paper load, enabling demand response, efficiency, and industrial electricity rates, while regulators assess impacts on ratepayers, grid reliability, mill viability, and savings.

 

Key Points

A four-year tariff letting the utility control the mill load for demand response, efficiency, and lower costs.

✅ Utility can increase or reduce daily consumption at the mill

✅ Projected savings of $10M annually for other ratepayers to 2023

✅ Regulators reviewing cost allocation, monitoring, and viability

 

Nova Scotia Power is scheduled to appear before government regulators Tuesday morning seeking approval for a unique discount rate for its largest customer.

Under the four-year plan, Nova Scotia Power would control the supply of electricity to Port Hawkesbury Paper, a move referenced in a grid operations report that urges changes, with the right to direct the company to increase or reduce daily consumption throughout the year.

The rate proposal is supported by the mill, which says it needs to lower its power bill to keep its operation viable.

The rate went into effect on Jan. 1 on a temporary basis, pending the outcome of a hearing this week before the Nova Scotia Utility and Review Board, amid broader calls for an independent body to lead electricity planning.

The mill accounts for 10 per cent of the provincial electricity load, even as a neighbouring utility pursues more Quebec power for the region, producing glossy paper used in magazines and catalogs.

Nova Scotia Power says controlling how much electricity the mill uses — and when — will allow it to operate the system much more efficiently, as it expands biomass generation initiatives, saving other customers $10 million a year until the rate expires in 2023.

Ceding control 'not an easy decision'
In its opening statement that was filed in advance, Port Hawkesbury Paper said ceding the control of its electrical supply to Nova Scotia Power was "not an easy decision" to make, but the company is confident the arrangement will work.

In September 2019, Nova Scotia Power and the mill jointly applied for an "extra large active demand control tariff," which would provide electricity to the mill for about $61 per megawatt hour, well below the full cost of generating the electricity.

The utility said "fully allocating costs" would result in "prices in excess of $80/MWh ... and [would] not [be] financially viable for the mill."

In its statement, Port Hawkesbury Paper said since the initial filing "there have been greater near term declines in market demand and pricing for PHP's product than was forecast at that time, continuing to put pressure on our business and further highlighting the need to maintain the balance provided for in the new tariff."

Consumer advocate sees 'advantage,' but will challenge
Bill Mahody represents Nova Scotia Power's 400,000 residential customers before the review board. He wants proof the mill will pay enough toward the cost of generating the electricity it uses, amid concerns over biomass use in the province today.

"We filed evidence, as have others involved in the proceeding, that would call into question whether or not the rate design is capturing all of those costs and that will be a significant issue before the board," Mahody said.

Still, he sees value in the proposal.

"This proposed rate gives Nova Scotia Power the ability to control that sizable Port Hawkesbury Paper load to the advantage of other ratepayers, as the province pursues more wind and solar projects, because Nova Scotia Power would be reducing the costs that other ratepayers are going to face," he said.

Mahody is also calling for a mechanism to monitor whether the mill's position actually improves to the point where it could pay higher rates.

"An awful lot can change during a four-year period, with new tidal power projects underway, and I think the board ought to have the ability to check in on this and make sure that their preferential rate continues to be justified," he said.

Major employer
Port Hawkesbury Paper, owned by Stern Partners in Vancouver, has received discounted power rates since it bought the idled mill in 2012. But the "load retention tariff" as it was called, expired at the end of 2019.

Regulators have accepted Nova Scotia Power's argument that it would cost other customers more if the mill ceased to operate.

The mill said it spends between $235 million and $265 million annually, employing 330 people directly and supporting 500 other jobs indirectly.

The Nova Scotia government pledged $124 million in financial assistance as part of the reopening in 2012.

Coal, Business Interests Support EPA in Legal Challenge to Affordable Clean Energy Rule

Affordable Clean Energy Rule Lawsuit pits EPA and coal industry allies against health groups over Clean Power Plan repeal, greenhouse gas emissions standards, climate change, public health, and state authority before the D.C. Circuit.

 

Key Points

A legal fight over EPA's ACE rule and CPP repeal, weighing emissions policy, state authority, climate, and public health.

✅ Challenges repeal of Clean Power Plan and adoption of ACE.

✅ EPA backed by coal, utilities; health groups seek stricter limits.

✅ D.C. Circuit to review emissions authority and state roles.

 

The largest trade association representing coal interests in the country has joined other business and electric utility groups in siding with the EPA in a lawsuit challenging the Trump administration's repeal of the Clean Power Plan.

The suit -- filed by the American Lung Association and the American Public Health Association -- seeks to force the U.S. Environmental Protection Agency to drop a new rule-making process that critics claim would allow higher levels of greenhouse gas emissions, further contributing to the climate crisis and negatively impacting public health.

The new rule, which the Trump administration calls the "Affordable Clean Energy rule" (ACE), "would replace the 2015 Clean Power Plan, which EPA has proposed to repeal because it exceeded EPA's authority. The Clean Power Plan was stayed by the U.S. Supreme Court and has never gone into effect," according to an EPA statement.

EPA has also moved to rewrite wastewater limits for coal power plants, signaling a broader rollback of related environmental requirements.

America's Power -- formerly the American Coalition for Clean Coal Electricity -- the U.S. Chamber of Commerce, the National Mining Association, and the National Rural Electric Cooperative Association have filed motions seeking to join the lawsuit. The U.S. Court of Appeals for the District of Columbia Circuit has not yet responded to the motion.

Separately, energy groups warned that President Trump and Energy Secretary Rick Perry were rushing major changes to electricity pricing that could disrupt markets.

"In this rule, the EPA has accomplished what eluded the prior administration: providing a clear, legal pathway to reduce emissions while preserving states' authority over their own grids," Hal Quinn, president and chief executive officer of the mining association, said when the new rule was released last month. "ACE replaces a proposal that was so extreme that the Supreme Court issued an unprecedented stay of the proposal, having recognized the economic havoc the mere suggestion of such overreach was causing in the nation's power grid."

Around the same time, a coal industry CEO blasted a federal agency's decision on the power grid as harmful to reliability.

The trade and business groups have argued that the Clean Power Plan, set by the Obama administration, was an overreach of federal power. Finalized in 2015, the plan was President Obama's signature policy on climate change, rooted in compliance with the Paris Climate Treaty. It would have set state limits on emissions from existing power plants but gave wide latitude for meeting goals, such as allowing plant operators to switch from coal to other electric generating sources to meet targets.

Former EPA Administrator Scott Pruitt argued that the rule exceeded federal statutory limits by imposing "outside the fence" regulations on coal-fired plants instead of regulating "inside the fence" operations that can improve efficiency.

The Clean Power Plan set a goal of reducing carbon emissions from power generators by 32 percent by the year 2030. An analysis from the Rhodium Group found that had states taken full advantage of the CPP's flexibility, emissions would have been reduced by as much as 72 million metric tons per year on average. Still, even absent federal mandates, the group noted that states are taking it upon themselves to enact emission-reducing plans based on market forces.

In its motion, America's Power argues the EPA "acknowledged that the [Best System of Emission Reduction] for a source category must be 'limited to measures that can be implemented ... by the sources themselves.'" If plants couldn't take action, compliance with the new rule would require the owners or operators to buy emission rate credits that would increase investment in electricity from gas-fired or renewable sources. The increase in operating costs plus federal efforts to shift power generation to other sources of energy, thereby increasing costs, would eventually force the coal-fired plants out of business.

In related proceedings, renewable energy advocates told FERC that a DOE proposal to subsidize coal and nuclear plants was unsupported by the record, highlighting concerns about market distortions.

"While we are confident that EPA will prevail in the courts, we also want to help EPA defend the new rule against others who prefer extreme regulation," said Michelle Bloodworth, president and CEO of America's Power.

"Extreme regulation" to one group is environmental and health protections to another, though.

Howard A. Learner, executive director of the Environmental Law & Policy Center of the Midwest, defended the Clean Power Plan in an opinion piece published in June.

"The Midwest still produces more electricity from coal plants than any other region of the country, and Midwesterners bear the full range of pollution harms to public health, the Great Lakes, and overall environmental quality," Learner wrote. "The new [Affordable Clean Energy] Rule is a misguided policy, moves our nation backward in solving climate change problems, and misses opportunities for economic growth and innovation in the global shift to renewable energy. If not reversed by the courts, as it should be, the next administration will have the challenge of doing the right thing for public health, the climate and our clean energy future."

When it initially filed its lawsuit against the Trump administration's Affordable Clean Energy Rule, the American Lung Association accused the EPA of "abdicat[ing] its legal duties and obligations to protect public health." It also referred to the new rule as "dangerous."
