The administration of Gov. Deval Patrick is urging the New England electric grid operator to allow the closure of the coal- and oil-fired Salem Harbor Power Station in Salem, Mass., according to a letter posted online by a Boston environmental nonprofit.

In response, a spokesman for the grid operator, ISO New England, said the organization is not blocking the closure and is looking for solutions that would eliminate the need for the plant.

The company that owns the Salem power plant, Dominion Resources Inc. of Virginia, said in November that the plant is expected to close within five years. But ISO has signaled that this could pose problems for the reliability of the grid, since the 745-megawatt Salem Harbor plant is among the stateÂ’s largest sources of power.

In a recent letter to ISO New England — posted by the Conservation Law Foundation — state energy and environmental secretary Ian Bowles asked that “all cost effective options” be considered to “allow Salem Harbor to be retired while safeguarding reliability.”

“I am concerned that if Salem Harbor is not allowed to retire, Dominion Energy will be forced to spend hundreds of millions of dollars on environmental upgrades to extend the life of an outmoded plant,” Bowles wrote.

“In my view, Massachusetts consumer dollars should be invested in clean energy solutions — better transmission, efficiency, conservation and renewables — rather than in keeping open an older generation coal plant that cannot compete economically and struggles to meet standards necessary to protect our environmental and public health,” wrote Bowles, who leaves the Patrick Administration at the end of the year.

In a recent e-mail, ISO spokesman Marcia Blomberg said that “the ISO is not preventing Dominion from retiring its Salem Harbor units, and we don’t have the authority to do so.”

“The ISO is aware of the situation and in accordance with our responsibility to ensure reliability, we have been studying the power system needs on the North Shore,” she said. “We are working with the utility companies to design and implement a transmission solution that will eliminate the reliability need for Salem Harbor.”

Dominion spokesman Dan Genest said previously that the company is basing its Salem Harbor closure plans on the expectation that the U.S. Environmental Protection agency will put stricter regulations on nitrogen oxide and sulfur dioxide emissions in place by 2015 or 2017.

Genest said the company hasn’t set a date for closing the plant, which has been open since 1951 and employs 145 people. The company could see scenarios in which the plant does not end up closing, he said — such as if the EPA regulations are delayed, or if ISO rules that the plant is crucial for grid reliability.

Environmental advocates, such as the Conservation Law Foundation, have called for Salem Harbor to either close or put stronger environmental measures put in place. In June, the organization filed a federal lawsuit alleging hundreds of violations of the U.S. Clean Air Act at the power plant in recent years.

Coal plant operators around the U.S. have also been under increasing pressure from government and public scrutiny due to climate change, since coal produces the largest amount of carbon dioxide emissions of any power source.

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.

Are major changes coming to your electric bill?

California Income-Based Electricity Rates propose a fixed monthly fee set by income as utilities and the CPUC weigh progressive pricing, aiming to cut low-income bills while PG&E, SCE, and SDG&E retain usage-based charges.

 

Key Points

CPUC plan adds income-tiered fixed fees to lower low-income bills while keeping per-kWh usage charges.

✅ Adds fixed monthly fees by income to complement per-kWh charges

✅ Cuts bills for low-income households; higher earners pay more

✅ Utilities say revenue neutral; conservation signals preserved

 

California’s electric bills — already some of the highest in the nation — are rising as electricity prices soar across the state, but regulators are debating a new plan to charge customers based on their income level. 

Typically what you pay for electricity depends on how much you use. But the state’s three largest electric utilities — Southern California Edison Company, Pacific Gas and Electric Company and San Diego Gas & Electric Company — have proposed a plan to charge customers not just for how much energy they use, but also based on their household income, moving toward income-based flat-fee utility bills over time. Their proposal is one of several state regulators received designed to accommodate a new law to make energy less costly for California’s lowest-income customers.

Some state Republican lawmakers are warning the changes could produce unintended results, such as weakening incentives to conserve electricity or raising costs for customers using solar energy, and some have introduced a plan to overturn the charges in the Legislature.

But the utility companies say the measure would reduce electricity bills for the lowest income customers. Those residents would save about $300 per year, utilities estimate.

California households earning more than $180,000 a year would end up paying an average of $500 more a year on their electricity bills, according to the proposal from utility companies. 

The California Public Utilities Commission’s deadline for deciding on the suggested changes is July 1, 2024, as regulators face calls for action from consumers and advocates. The proposals come at a time when many moderate and low-income families are being priced out of California by rising housing costs.  

Who wants to change the fee structure?
Lawmakers passed and Gov. Gavin Newsom signed a comprehensive energy bill last summer that mandates restructuring electricity pricing across the state. 

The Legislature passed the measure in a “trailer-bill” process that limited deliberation. Included in the 21,000-word law are a few sentences requiring the public utilities commission to establish a “fixed monthly fee” based on each customer’s household income. 

A similar idea was first proposed in 2021 by researchers at UC Berkeley and the nonprofit thinktank Next 10. Their main recommendation was to split utility costs into two buckets. Fixed charges, which everyone has to pay just to be connected to the energy grid, would be based on income levels. Variable charges would depend on how much electricity you use.

Utilities say that part of customers’ bills still will be based on usage, but the other portion will reduce costs for lower- and middle-income customers, who “pay a greater percentage of their income towards their electricity bill relative to higher income customers,” the utilities argued in a recent filing. 

They said the current billing system is unjust, regressive and fails to recognize differences in energy usage among households,

“When we were putting together the reform proposal, front and center in our mind were customers who live paycheck to paycheck, who struggle to pay for essentials such as energy, housing and food,” Caroline Winn, CEO of San Diego Gas & Electric in a statement. 

The utilities say in their proposal that the changes likely would not reduce or increase their revenues.

James Sallee, an associate professor at UC Berkeley, said the utilities’ prior system of billing customers mostly by measuring their electric use to pay for what are essentially fixed costs for power is inefficient and regressive. 

The proposed changes “will shift the burden, on average, to a more progressive system that recovers more from higher income households and less from lower income households,” he said.

Court reinstates constitutional challenge to Ontario's hefty ‘global adjustment’ electricity charge

Ontario Global Adjustment Charge faces constitutional scrutiny as a regulatory charge vs tax; Court of Appeal revives case over electricity pricing, feed-in tariff contracts, IESO policy, and hydro rate impacts on consumers and industry.

 

Key Points

A provincial electricity fee funding generator contracts, now central to a court fight over tax versus regulatory charge.

✅ Funds gap between market price and contracted generator rates

✅ At issue: regulatory charge vs tax under constitutional law

✅ Linked to feed-in tariff, IESO policy, and hydro rate hikes

 

Ontario’s court of appeal has decided that a constitutional challenge of a steep provincial electricity charge should get its day in court, overturning a lower-court judgment that had dismissed the legal bid.

Hamilton, Ont.-based National Steel Car Ltd. launched the challenge in 2017, saying Ontario’s so-called global adjustment charge was unconstitutional because it is a tax — not a valid regulatory charge — that was not passed by the legislature.

The global adjustment funds the difference between the province’s hourly electricity price and the price guaranteed under contracts to power generators. It is “the component that covers the cost of building new electricity infrastructure in the province, maintaining existing resources, as well as providing conservation and demand management programs,” the province’s Independent Electricity System Operator says.

However, the global adjustment now makes up most of the commodity portion of a household electricity bill, and its costs have ballooned, as regulators elsewhere consider a proposed 14% rate hike in Nova Scotia.

Ontario’s auditor general said in 2015 that global adjustment fees had increased from $650 million in 2006 to more than $7 billion in 2014. She added that consumers would pay $133 billion in global adjustment fees from 2015 to 2032, after having already paid $37 billion from 2006 to 2014.

National Steel Car, which manufactures steel rail cars and faces high electricity rates that hurt Ontario factories, said its global adjustment costs went from $207,260 in 2008 to almost $3.4 million in 2016, according to an Ontario Court of Appeal decision released on Wednesday.

The company claimed the global adjustment was a tax because one of its components funds electricity procurement contracts under a “feed-in tariff” program, or FIT, which National Steel Car called “the main culprit behind the dramatic price increases for electricity,” the decision said.

Ontario’s auditor general said the FIT program “paid excessive prices to renewable energy generators.” The program has been ended, but contracts awarded under it remain in place.


National Steel Car claimed the FIT program “was actually designed to accomplish social goals unrelated to the generation of electricity,” such as helping rural and indigenous communities, and was therefore a tax trying to help with policy goals.

“The appellant submits that the Policy Goals can be achieved by Ontario in several ways, just not through the electricity pricing formula,” the decision said.

National Steel Car also argued the global adjustment violated a provincial law that requires the government to hold a referendum for new taxes.

“The appellant’s principal claim is that the Global Adjustment was a ‘colourable attempt to disguise a tax as a regulatory charge with the purpose of funding the costs of the Policy Goals,’” the decision said. “The appellant pressed this argument before the motion judge and before this court. The motion judge did not directly or adequately address it.”

The Ontario government applied to have the challenge thrown out for having “no reasonable cause of action,” and a Superior Court judge did so in 2018, saying the global adjustment is not a tax.

National Steel Car appealed the decision, and the decision published Wednesday allowed the appeal, set aside the lower-court judgment, and will send the case back to Superior Court, where it could get a full hearing.

“The appellant’s claim is sufficiently plausible on the evidentiary record it put forward that the applications should not have been dismissed on a pleadings motion before the development of a full record,” wrote Justice Peter D. Lauwers. “It is not plain, obvious and beyond doubt that the Global Adjustment, and particularly the challenged component, is properly characterized as a valid regulatory charge and not as an impermissible tax.”

Jerome Morse of Morse Shannon LLP, one of National Steel Car’s lawyers, said the Ontario government would now have 60 days to decide whether to seek permission to appeal to the Supreme Court of Canada.

“What the court has basically said is, ‘this is a plausible argument, here are the reasons why it’s plausible, there was no answer to this,’” Morse told the Financial Post.

Ontario and the IESO had supported the lower-court decision, but there has been a change in government since the challenge was first launched, with Progressive Conservative Premier Doug Ford replacing the Liberals and Kathleen Wynne in power. The Liberals had launched a plan aimed at addressing hydro costs before losing in a 2018 election, the main thrust of which had been to refinance global adjustment costs.

Wednesday’s decision states that “Ontario’s counsel advised the court that the current Ontario government ‘does not agree with the former government’s electricity procurement policy (since-repealed).’

“The government’s view is that: ‘The solution does not lie with the courts, but instead in the political arena with political actors,’” it adds.

A spokesperson for Ontario Energy Minister Greg Rickford said in an email that they are reviewing the decision but “as this matter is in the appeal period, it would be inappropriate to comment.” 

Ontario had also requested to stay the matter so a regulator, the Ontario Energy Board, could weigh in, while the Nova Scotia regulator approved a 14% hike in a separate case.

“However, Ontario only sought this relief from the motion judge in the alternative, and given the motion judge’s ultimate decision, she did not rule on the stay,” Thursday’s decision said. “It would be premature for this court to rule on the issue, although it seems incongruous for Ontario to argue that the Superior Court is the convenient forum in which to seek to dismiss the applications as meritless, but that it is not the convenient forum for assessing the merits of the applications.”

National Steel Car’s challenge bears a resemblance to the constitutional challenges launched by Ontario and other provinces over the federal government’s carbon tax, but Justice Lauwers wrote “that the federal legislative scheme under consideration in those cases is distinctly different from the legislation at issue in this appeal.”

“Nothing in those decisions impacts this appeal,” the judge added.

Australian operator warns of reduced power reserves

Australia Electricity Supply Shortfall highlights AEMO's warning of reduced reserves as coal retirements outpace capacity, risking load shedding. Calls for 1GW strategic reserves and investment in renewables, storage, and dispatchable power in Victoria.

 

Key Points

It is AEMO's forecast of reduced reserves, higher outage risk, and a need for 1GW strategic backup capacity.

✅ Coal retirements outpacing firm, dispatchable capacity

✅ AEMO urges 1GW strategic reserves in Victoria and South Australia

✅ Investment needed: renewables, storage, grid and reliability services

 

Australia’s electricity operator has warned of threats to electricity supply including a shortfall in generation and reduced power reserves on the horizon.

The Australian Energy Market Operator (AEMO) has called for further investment in the country’s energy portfolio as retiring coal plants are replaced by intermittent renewables poised to eclipse coal, leaving the grid with less back-up capacity.

AEMO has said this increases the chances of supply interruption and load shedding.

It added the federal government should target 1GW of strategic reserves in the states most at risk – Victoria and South Australia, even as the Prime Minister has ruled out taxpayer-funded power plants in the current energy battle.

CEO of the Clean Energy Council, Kane Thornton, said the shortfall in generation, reflected in a short supply of electricity, was due a decade of indecisiveness and debate leading to a “policy vacuum”.

He added: “The AEMO report revealed that the new projects added to the system under the renewable energy target will help to improve reliability over the next few years.

“We need to accept that the energy system is in transition, with lessons from dispatchable power shortages in Europe, and long term policy is now essential to ensure private investment in the most efficient new energy technology and solutions.”

BC Hydro cryptic about crypto mining electricity use

BC Hydro Crypto Mining Moratorium pauses high-load connection requests, as BCUC reviews electricity demand, gigawatt-hours and megawatt load forecasts, data center growth, and potential rate impacts on the power grid and industrial customers.

 

Key Points

A BC order pausing crypto mining connections while BC Hydro and BCUC assess load, grid impacts, and ratepayer risks.

✅ 18-month pause on new high-load crypto connections

✅ 1,403 MW in requests suspended; 273 MW existing or pending

✅ Seeks to manage demand, rates, and grid reliability

 

In its Nov. 1, 2022 load update briefing note to senior executives of the Crown corporation, BC Hydro shows that the entire large industrial sector accounted for 6,591 gigawatt-hours during the period – one percent less than forecast in the service plan.

BC Hydro censored load statistics about crypto mining, coal mining and chemicals from the briefing note, which was obtained under the freedom of information law and came amid scrutiny over B.C. electricity imports because it feared that disclosure would harm Crown corporation finances and third-party business interests.

Crypto mining requires high-powered computers to run and be cooled around the clock constantly. So much so that cabinet ordered the BC Utilities Commission (BCUC) last December to place an 18-month moratorium on crypto mining connection requests, while other jurisdictions, such as the N.B. Power crypto review, undertook similar pauses to assess impacts.


In a news release, the government said 21 projects seeking 1,403 megawatts were temporarily suspended. The government said that would be enough to power 570,000 homes or 2.1 million electric vehicles for a year.

A report issued by BC Hydro before Christmas said there were already 166 megawatts of power from operational projects at seven sites. Another six projects with 107 megawatts were nearing connection, bringing its total load to 273 megawatts.

Richard McCandless, a retired assistant deputy minister who analyzes the performance of BC Hydro and the Insurance Corp of British Columbia, said China's May 2021 ban on crypto mining had a major ripple effect on those seeking cheap and reliable power.

"When China cracked down, these guys fled to different areas," McCandless said in an interview. "So they took their computers and went somewhere else. Some wound up in B.C."

He said BC Hydro's secrecy about crypto loads appears rooted in the Crown corporation underestimating load demand, even as new generating stations were commissioned to bolster capacity.

"Crypto is up so dramatically; they didn't want to show that," McCandless said. "Maybe they didn't want to be seen as being asleep at the switch."

Indeed, BCUC's April 21 decision on BC Hydro's 2021 revenue forecasts through the 2025 fiscal year included BC Hydro's forecast increase for crypto and data centres of about 100 gigawatt-hours through fiscal 2024 before returning to 2021 levels by 2025. In addition, the BCUC document said that BC Hydro's December 2020 load forecast was lower than the previous one because of project cancellations and updated load requests, amid ongoing nuclear power debate in B.C.

"Given the segment's continued uncertainty and volatility, the forecast assumes these facilities are not long-lived," the BC Hydro application said.

A September 2022 report to the White House titled "Crypto-Assets in the United States" said increased electricity demand from crypto-asset mining could lead to rate increases.

"Crypto-asset mining in upstate New York increased annual household electric bills by [US]$82 and annual small business electric bills by [US]$164, with total net losses from local consumers and businesses estimated to be [US]$179 million from 2016-2018," the report said. The information mentioned Plattsburgh, New York's 18-month moratorium in 2018. Manitoba announced a similar suspension almost a month before B.C.

B.C.'s total core domestic load of 23,666 gigawatt-hours was two percent higher than the service plan amid BC Hydro call for power planning, with commercial and light industrial (9,198 gigawatt-hours) and residential (7,877 gigawatt-hours) being the top two customer segments.

"A cooler spring and warmer summer supported increased loads, as the Western Canada drought strained hydropower production regionally. However, warmer daytime temperatures in September impacted heating more than cooling," said the briefing note.

"Commercial and light industrial consumption benefited from warmer temperatures in August but has also been impacted to a lesser degree by the reduced heating load in the first three weeks of October."

Loads improved relative to 2021, but offices, retail businesses and restaurants remained below pre-pandemic levels. Education, recreation and hotel sectors were in line with pre-pandemic levels. Light industrial sector growth offset the declines.

For heavy industry, pulp and paper electricity use was 15 percent ahead of forecast, but wood manufacturing was 16 percent below forecast. The briefing note said oil and gas grew nine percent relative to the previous year but, alongside ongoing LNG power demand, fell nine percent below the service plan.

Pacific Northwest's Renewable Energy Goals Hindered

Pacific Northwest Transmission Bottleneck slows clean energy progress as BPA's aging grid constrains renewable interconnections, delaying wind, solar, and data center growth; decarbonization targets depend on transmission upgrades, new substations, and policy reform.

 

Key Points

An interconnection and capacity shortfall on BPA's aging grid that delays renewables and impedes clean energy goals.

✅ BPA approvals lag: 1 of 469 projects since 2015.

✅ Yakama solar waits for substation upgrades until 2027.

✅ Data centers and decarbonization targets face grid constraints.

 

Oregon and Washington have set ambitious targets to decarbonize their power sectors, aiming for 100% clean electricity in the coming decades. However, a significant obstacle stands in the way: the region's aging and overburdened transmission grid, underscoring why 100% renewables remain elusive even as momentum builds.

The Grid Bottleneck

The BPA operates a transmission system that is nearly a century old in some areas, and its capacity has not expanded sufficiently to accommodate the influx of renewable energy projects, reflecting stalled grid spending in many parts of the U.S., according to recent analyses. Since 2015, 469 large renewable projects have applied to connect to the BPA's grid; however, only one has been approved—a stark contrast to other regions in the country. This bottleneck has left numerous wind and solar projects in limbo, unable to deliver power to the grid.

One notable example is the Yakama Nation's solar project. Despite receiving a $32 million federal grant under the bipartisan infrastructure law as part of a broader grid overhaul for renewables, the tribe faces significant delays. The BPA estimates that it will take until 2027 to complete the necessary upgrades to the transmission system, including a new substation, before the solar array can be connected. This timeline poses a risk of losing federal funding if the project isn't operational by 2031.

Economic and Environmental Implications

The slow pace of grid expansion has broader implications for the region's economy and environmental goals. Data centers and other energy-intensive industries are increasingly drawn to the Pacific Northwest due to its clean energy potential, while interregional projects like the Wyoming-to-California wind link illustrate how transmission access can unlock supply. However, without adequate infrastructure, these industries may seek alternatives elsewhere. Additionally, the inability to integrate renewable energy efficiently hampers efforts to reduce greenhouse gas emissions and combat climate change.

Policy Challenges and Legislative Efforts

Efforts to address the grid limitations through state-level initiatives have faced challenges, even as a federal rule to boost transmission advances nationally. In 2025, both Oregon and Washington considered legislation to establish state bonding authorities aimed at financing transmission upgrades. However, these bills failed to pass, leaving the BPA as the primary entity responsible for grid expansion. The BPA's unique structure—operating as a self-funded federal agency without direct state oversight—has made it difficult for regional leaders to influence its decision-making processes.

Looking Ahead

The Pacific Northwest's renewable energy aspirations hinge on modernizing its transmission infrastructure, aligning with decarbonization strategies that emphasize grid buildout. While the BPA has proposed several projects to enhance grid capacity, the timeline for completion remains uncertain. Without significant investment and policy reforms, the region risks falling behind in the transition to a clean energy future. Stakeholders across Oregon and Washington must collaborate to advocate for necessary changes and ensure that the grid can support the growing demand for renewable energy.

The Pacific Northwest's commitment to clean energy is commendable, but achieving these goals requires overcoming substantial infrastructure challenges, and neighboring jurisdictions such as British Columbia have pursued B.C. regulatory streamlining to accelerate projects. Addressing the limitations of the BPA's transmission system is critical to unlocking the full potential of renewable energy in the region. Only through concerted efforts at the federal, state, and local levels can Oregon and Washington hope to realize their green energy ambitions.
