The city that inventor Thomas Edison electrified 125 years ago has completed the transition from direct to alternating current, helping to erase the vestiges of a feud between giants of invention.

The Consolidated Edison utility pulled the plug on direct current service.

The change means that Con Ed now exclusively uses the alternating current system invented by Nikola Tesla. The utility is named for Edison, whose Pearl Street Station in Manhattan was the first U.S. central electrical power plant, serving 59 customers with direct current beginning in 1882.

In the so-called "war of currents," Edison feuded with Tesla and George Westinghouse over which transmission method to adopt — even going so far as to publicly electrocute animals in the hopes of showing AC was too dangerous.

Alternating current proved superior as transformers allowed electricity to travel over long-distance wires. As AC gained prevalence over DC across the world, Con Ed froze the development of the DC system in 1928 but continued to supply New York's major DC customers with the existing system.

In January 1998, Con Ed began to eliminate DC service. At that time, there were more than 4,600 DC customers. By last year, there were only 60.

Con Ed spokesman Robert McGee said some of the city's elevators still operate with DC using rectifiers that convert the utility's AC service.

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.

Washington AG Leads Legal Challenge Against Trump’s Energy Emergency

Washington-Led Lawsuit Against Energy Emergency challenges President Trump's executive order, citing state rights, environmental reviews, permitting, and federal overreach; coalition argues record energy output undermines emergency claims in Seattle federal court.

 

Key Points

Multistate suit to void Trump's energy emergency, alleging federal overreach and weakened environmental safeguards.

? Challenges executive order's legal basis and scope

? Claims expedited permitting skirts environmental reviews

? Seeks to halt emergency permits for non-emergencies

 

In a significant legal move, Washington State Attorney General Nick Brown has spearheaded a coalition of 15 states in filing a lawsuit against President Donald Trump's executive order declaring a national energy emergency. The lawsuit, filed in federal court in Seattle on May 9, 2025, challenges the legality of the emergency declaration, which aims to expedite permitting processes for fossil fuel projects in pursuit of an energy dominance vision by bypassing key environmental reviews.

Background of the Energy Emergency Declaration

President Trump's executive order, issued on January 20, 2025, asserts that the United States faces an inadequate and unreliable energy grid, particularly affecting the Northeast and West Coast regions. The order directs federal agencies, including the Army Corps of Engineers and the Department of the Interior, to utilize "any lawful emergency authorities" to facilitate the development of domestic energy resources, with a focus on oil, gas, and coal projects. This includes expediting reviews under the Clean Water Act, Endangered Species Act, the National Environmental Policy Act, and the National Historic Preservation Act, potentially reducing public input and environmental oversight.

Legal Grounds for the Lawsuit

The coalition of states, led by Washington and California, argues that the emergency declaration is an overreach of presidential authority, echoing disputes over the Affordable Clean Energy rule in federal courts. They contend that U.S. energy production is already at record levels, and the declaration undermines state rights and environmental protections. The lawsuit seeks to have the executive order declared unlawful and to halt the issuance of emergency permits for non-emergency projects. 

Implications for Environmental Protections

Critics of the energy emergency declaration express concern that it could lead to significant environmental degradation. By expediting permitting processes, including geothermal permitting, and reducing public participation, the order may allow projects to proceed without adequate consideration of their impact on water quality, wildlife habitats, and cultural resources. Environmental advocates argue that such actions could set a dangerous precedent, enabling future administrations to bypass essential environmental safeguards under the guise of national emergencies, even as the EPA advances new pollution limits for coal and gas plants to address the climate crisis.

Political and Legal Reactions

The Trump administration defends the executive order, asserting that the president has the authority to declare national emergencies and that the energy emergency is necessary to address perceived deficiencies in the nation's energy infrastructure and potential electricity pricing changes debated by industry groups. However, legal experts suggest that the broad application of emergency powers in this context may face challenges in court. The outcome of the lawsuit could have significant implications for the balance of power between state and federal authorities, as well as the future of environmental regulations in the United States.

The legal challenge led by Washington State Attorney General Nick Brown represents a critical juncture in the ongoing debate over energy policy and environmental protection. As the lawsuit progresses through the courts, it will likely serve as a bellwether for future conflicts between state and federal governments regarding the scope of executive authority and the preservation of environmental standards, amid ongoing efforts to expand uranium and nuclear energy programs nationwide. The outcome may set a precedent for how national emergencies are declared and managed, particularly concerning their impact on state governance and environmental laws.

Here's what we know about the mistaken Pickering nuclear alert one week later

Pickering Nuclear Alert Error prompts Ontario investigation into the Alert Ready emergency alert system, Pelmorex safeguards, and public response at Pickering Nuclear Generating Station, including potassium iodide orders and geo-targeted notification issues.

 

Key Points

A mistaken Ontario emergency alert about the Pickering plant, now under probe for human error and system safeguards.

✅ Investigation led by Emergency Management Ontario

✅ Alert Ready and Pelmorex safeguards under review

✅ KI pill demand surged; geo-targeting questioned

 

A number of questions still remain a week after an emergency alert was mistakenly sent out to people across Ontario warning of an unspecified incident at the Pickering Nuclear Generating Station. 

The province’s solicitor general has stepped in and says an investigation into the incident should be completed fairly quickly according to the minister.

However, the nuclear scare has still left residents on edge with tens of thousands of people ordering potassium iodide, or KI, pills that protect the body from radioactive elements in the days following the incident.

Here’s what we know and still don’t know about the mistaken Pickering nuclear plant alert:

Who sent the alert?

According to the Alert Ready Emergency Alert System website, the agency works with several federal, provincial and territorial emergency management officials, Environment and Climate Change Canada and Pelmorex, a broadcasting industry and wireless service provider, to send the alerts.

Martin Belanger, the director of public alerting for Pelmorex, a company that operates the alert system, said there are a number of safeguards built in, including having two separate platforms for training and live alerts.

"The software has some steps and some features built in to minimize that risk and to make sure that users will be able to know whether or not they're sending an alert through the... training platform or whether they're accessing the live system in the case of a real emergency," he said.

Only authorized users have access to the system and the province manages that, Belanger said. Once in the live system, features make the user aware of which platform they are using, with various prompts and messages requiring the user's confirmation. There is a final step that also requires the user to confirm their intent of issuing an alert to cellphones, radio and TVs, Belanger said.

Last Sunday, a follow-up alert was sent to cellphones nearly two hours after the original notification, and during separate service disruptions such as a power outage in London residents also sought timely information.

What has the investigation revealed?

It’s still unclear as to how exactly the alert was sent in error, but Solicitor General Sylvia Jones has tapped the Chief of Emergency Management Ontario to investigate.

"It's very important for me, for the people of Ontario, to know exactly what happened on Sunday morning," Jones said.

Jones said initial observations suggest human error was responsible for the alert that was sent out during routine tests of the emergency alert.

“I want to know what happened and equally important, I want some recommendations on insurances and changes we can make to the system to make sure it doesn't happen again,” Jones said.

Jones said she expects the results of the probe to be made public.

Can you unsubscribe from emergency alerts?

It’s not possible to opt out of receiving the alerts, according to the Alert Ready Emergency Alert System website, and Ontario utilities warn about scams to help customers distinguish official notices.

“Given the importance of warning Canadians of imminent threats to the safety of life and property, the CRTC requires wireless service providers to distribute alerts on all compatible wireless devices connected to an LTE network in the target area,” the website reads.

The agency explains that unlike radio and TV broadcasting, the wireless public alerting system is geo-targeted and is specific to the a “limited area of coverage”, and examples like an Alberta grid alert have highlighted how jurisdictions tailor notices for their systems.

“As a result, if an emergency alert reaches your wireless device, you are located in an area where there is an imminent danger.”

The Pickering alert, however, was received by people from as far as Ottawa to Windsor.

Is the Pickering Nuclear Generating Station closing?

The Pickering nuclear plant has been operating since 1971, and had been scheduled to be decommissioned this year, but the former Liberal government -- and the current Progressive Conservative government -- committed to keeping it open until 2024. Decommissioning is now set to start in 2028.

It operates six CANDU reactors, and in contingency planning operators have considered locking down key staff to maintain reliability, generates 14 per cent of Ontario's electricity and is responsible for 4,500 jobs across the region, according to OPG, while utilities such as Hydro One's relief programs have supported customers during broader crises.

What should I do if I receive an emergency alert?

Alert Ready says that if you received an alert on your wireless device it’s important to take action “safely”.

“Stop what you are doing when it is safe to do so and read the emergency alert,” the agency says on their website.

“Alerting authorities will include within the emergency alert the information you need and guidance for any action you are required to take, and insights from U.S. grid pandemic response underscore how critical infrastructure plans intersect with public safety.”

“This could include but is not limited to: limit unnecessary travel, evacuate the areas, seek shelter, etc.”

The wording of last Sunday's alert caused much initial confusion, warning residents within 10 kilometres of the plant of "an incident," though there was no "abnormal" release of radioactivity and residents didn't need to take protective steps, but emergency crews were responding.

“In the event of a real emergency, the wording would be different,” Jones said.

Notley announces plans to move Alberta's electricity grid to net-zero by 2035 if elected

Alberta NDP Net-Zero Electricity Plan targets a 2035 clean grid, expands renewable energy, cuts emissions, creates jobs, and boosts economic diversification and rural connectivity, aligning Alberta with Canada's 2050 climate goals.

 

Key Points

A policy to achieve a net-zero electricity grid by 2035, advance renewable energy, cut emissions, and grow jobs.

✅ Net-zero electricity grid target set for 2035

✅ Scales renewable energy and emissions reductions

✅ Focus on jobs, rural connectivity, and diversification

 

Ahead of the NDP’s weekend convention, Alberta’s Opposition leader has committed to transforming the province’s energy sector and moving the province’s electricity grid to net-zero by 2035, despite debate over the federal 2035 net-zero electricity grid target in other provinces, should an orange crush wash over Alberta in the next election.

NDP Leader Rachel Notley said they would achieve this as part of the path towards Canada’s 2050 net-zero emissions goal, aligning with broader clean grids trends, which will help preserve and create jobs in the province.

“I think it’s an important goal. It’s a way of framing the work that we’re going to do within our energy industry and our energy sector, including how Alberta produces and pays for electricity going forward,” said Notley. “We know the world is moving toward different objectives and we still have the ability to lead on that front, but we need to lay down the markers early and focus on reaching those goals.”

Premier Jason Kenney has previously called the 2050 target “aspirational,” and, as the electricity sector faces profound change in Alberta, Notley said, once the work begins, it’s likely they would meet the objective earlier than proposed to reduce greenhouse gas emissions that contribute to global warming.

This is just one key issue that will be addressed at the party’s online convention, which is the first since the NDP’s defeat by the UCP in the last provincial election. Notley said other key issues will address economic diversification, economic recovery, job creation and social issues, as Alberta’s electricity market is headed for a reshuffle too. The focus, as she puts it, is “jobs, jobs, jobs.”

Attendees will also debate more than 140 policy resolutions over the weekend, including the development of a safe supply drug policy, banning coal mining in the Rocky Mountains and providing paid sick leave for workers.

Outside the formal agenda, debate over electricity market competition continues in Alberta as stakeholders weigh options.

Notley said an area of growing focus for the NDP will be rural Alberta, which is typically a conservative stronghold. One panel presentation during the convention will focus on connecting and building relationships with rural Albertans and growing the NDP profile in those areas.

“We think that we have a lot to offer rural Alberta and that, quite frankly, the UCP and (Kenney), in particular, have profoundly taken rural Alberta for granted,” she said. “Because of that, we think with a renewed energy amongst our membership to go out to parts of the province where we haven’t been previously as active, and talk about what they have been subjected to in the last two years, that we have huge opportunities there.”

Delegates will be asked to support a call for high-speed internet coverage across Alberta, which would remove barriers to access in rural Alberta and Indigenous communities, said the convention guidebook.

The convention comes as the NDP has a wide lead on the UCP, according to the latest polls. A Leger online survey of 1,001 Albertans conducted between March 5 to 8 found 40 per cent of respondents support the NDP, compared to just 20 per cent for the UCP.

Notley said it’s “encouraging” to see, but they aren’t taking anything for granted.

“I’ve always believed that Alberta Democrats have to work twice as hard as anybody else in the political spectrum, or the political arena,” she said. “So what we’re going to do is continue to do exactly what we have been, not only being a strong and I would argue fearless Opposition, but also trying to match every oppositional position with something that is propositional — offering Albertans a different vision, including an Alberta path to clean electricity where possible.”

Ontario Teachers' Plan Acquires Brazilian Electricity Transmission Firm Evoltz

Ontario Teachers' Evoltz Acquisition expands electricity transmission in Brazil, adding seven grid lines across ten states, aligning infrastructure strategy with inflation-linked cash flows, renewable energy integration, Latin America and net-zero objectives pending regulatory approvals.

 

Key Points

A 100% purchase of Brazil's Evoltz, adding seven grid lines and delivering stable, inflation-linked cash flows.

✅ 100% stake in Evoltz with seven transmission lines

✅ Aligns with net-zero and renewable energy strategy

✅ Inflation-linked, core infrastructure cash flows in Brazil

 

The Ontario Teachers’ Pension Plan has acquired Evoltz Participações, an electricity transmission firm in Brazil, from US asset manager TPG. 

The retirement system took a 100% stake in the energy firm, Ontario Teachers’ said Monday. The acquisition has netted the pension fund seven electricity transmission lines that service consumers and businesses across 10 states in Brazil, amid dynamics similar to electricity rate reductions for businesses seen in Ontario. The firm was founded by TPG just three years ago. 

“Our strategy focuses on allocating significant capital to high-quality core infrastructure assets with lower risks and stable inflation-linked cash flows,” Dale Burgess, senior managing director of infrastructure and natural resources at Ontario Teachers, said in a statement. “Electricity transmission businesses are particularly attractive given their importance in facilitating a transition to a low-carbon economy.” 

The pension fund has invested in other electricity distribution companies recently. In March, Ontario Teachers’ took a 40% stake in Finland’s Caruna, and agreed to acquire a 25% stake in SSEN Transmission in the UK grid. For more than a decade, it has maintained a 50% stake in Chile-based transmission firm Saesa. 

The investment into Evoltz demonstrates Ontario Teachers’ growing portfolio in Brazil and Latin America, while activity in Ontario such as the Peterborough Distribution sale reflects ongoing utility consolidation. In 2016, the firm, with the Canada Pension Plan Investment Board (CPPIB), invested in toll roads in Mexico. They took a 49% stake with Latin American infrastructure group IDEAL. 

Evoltz, which delivers renewable energy, will also help decarbonize the pension fund’s portfolio. In January, the fund pledged to reach net-zero carbon emissions by 2050. Last year, Ontario Teachers’ issued its first green bond offering. The $890 million 10-year bond will help the retirement system fund sustainable investments aligned with policy measures like Ontario's subsidized hydro plan during COVID-19. 

However, Ontario Teachers’ has also received criticism for its investment into parts of Abu Dhabi’s gas pipeline network, and investor concerns about Hydro One highlight sector uncertainties. Last summer, it joined other institutional investors in investing $10.1 billion for a 49% stake. 

As of December, Ontario Teachers’ reached a portfolio with C$221.2 billion (US$182.5 billion) in assets. Since 1990, the fund has maintained a 9.6% annualized return. Last year, it missed its benchmark with an 8.6% return, with examples such as Hydro One shares fall after shake-up underscoring market volatility.

The pension fund expects the deal will close later this fall, pending closing conditions and regulatory approvals, including decisions such as the OEB combined T&D rates ruling that shape utility economics.

PG&E’s Pandemic Response Includes Precautionary Health and Safety Actions; Moratorium on Customer Shutoffs for Nonpayment

PG&E COVID-19 Shutoff Moratorium suspends service disconnections, offers flexible payment plans, and expands customer support with safety protocols, social distancing, and public health guidance for residential and commercial utility customers during the pandemic.

 

Key Points

A temporary halt to utility shutoffs with flexible payment plans to support PG&E customers during COVID-19.

✅ Suspends shutoffs for residential and commercial accounts

✅ Offers most flexible payment plans upon COVID-19 hardship

✅ Enhances safety: social distancing, PPE, remote work protocols

 

Pacific Gas and Electric Company has announced that due to the COVID-19 pandemic, it has voluntarily implemented a moratorium on service disconnections for non-payment, effective immediately. This suspension, similar to policies in New Jersey and New York, will apply to both residential and commercial customers and will remain in effect until further notice. To further support customers who may be impacted by the pandemic, PG&E will offer its most flexible pay plans to customers who indicate either an impact or hardship as a result of COVID-19. PG&E will continue to monitor current events and identify opportunities to support our customers and communities through concrete actions.

In addition to the moratorium on service shut-offs, PG&E’s response to the COVID-19 pandemic is focused on efforts to protect the health and safety of its customers, employees, contractors and the communities it serves, including ongoing wildfire risk reduction efforts that continue alongside its pandemic response. Actions the company has taken include providing guidance for employees who have direct customer contact to take social distancing precautionary measures, such as avoiding handshakes and wearing disposable nitrile gloves while in customers' homes, and continuing safety work related to power line-related fires across its service area.

Customers who visit local offices to pay bills and are sick or experiencing symptoms are being asked to use other payment options such as online or by phone, as seen when Texas utilities waived fees during the pandemic, at 1-877-704-8470.

“We recognize that this is a rapidly changing situation and an uncertain time for many of our customers. Our most important responsibility is the health and safety of our customers and employees. We also want to provide some relief from the stress and financial challenges many are facing during this worldwide, public health crisis, and with rates set to stabilize in 2025 the company remains focused on affordability. We understand that many of our customers may experience a personal financial strain due to the slowdown in the economy related to the pandemic, and programs like the Wildfire Assistance Program can help eligible customers,” said Chief Customer Officer and Senior Vice President Laurie Giammona.

Internally, the company is taking advanced cleaning measures, communicating best practices frequently with employees, and is asking its leaders to let employees work remotely if their job allows, while avoiding critical business disruption. PG&E has activated an enterprise-wide incident response team and is vigilantly monitoring the Centers for Disease Control and Prevention and World Health Organization for updates related to the virus. The company is committed to continue addressing customer service needs and does not expect any disruption in gas or electric service due to the public health crisis.
