Destroying sewage while producing power

U.S. Natural Gas Power Demand is surging for electricity generation amid summer heat, with ERCOT, Texas grid reserves tight, EIA reporting coal and nuclear retirements, renewables intermittency, and pipeline expansions supporting combined-cycle capacity and prices.

Key Points

It is rising use of natural gas for power, driven by summer heat, plant retirements, and new combined-cycle capacity.

✅ ERCOT reserve margin 9%, below 14% target in Texas

✅ Gas share of U.S. power near 40-43% this summer

✅ Coal and nuclear retirements shift capacity to combined cycle

As the hot months linger, it will be natural gas that is leaned on most to supply the electricity that we need to run our air conditioning loads on the grid and keep us cool.

And this is surely a great and important thing: "Heat causes most weather-related deaths, National Weather Service says."

Generally, U.S. gas demand for power in summer is 35-40% higher than what it was five years ago, with so much more coming (see Figure).

The good news is regions across the country are expected to have plenty of reserves to keep up with power demand.

The only exception is ERCOT, covering 90% of the electric load in Texas, where a 9% reserve margin is expected, below the desired 14%.

Last summer, however, ERCOT’s reserve margin also was below the desired level, yet the grid operator maintained system reliability with no load curtailments.

Simply put, other states are very lucky that Texas has been able to maintain gas at 50% of its generation, despite being more than justified to drastically increase that.

At about 1,600 Bcf per year, the flatness of gas for power demand in Texas since 2000 has been truly remarkable, especially since Lone Star State production is up 50% since then.

Increasingly, other U.S. states (and even countries) are wanting to import huge amounts of gas from Texas, a state that yields over 25% of all U.S. output.

Yet if Texas justifiably ever wants to utilize more of its own gas, others would be significantly impacted.

At ~480 TWh per year, if Texas was a country, it would be 9th globally for power use, even ahead of Brazil, a fast growing economy with 212 million people, and France, a developed economy with 68 million people.

In the near-term, this explains why a sweltering prolonged heat wave in July in Texas, with a hot Houston summer setting new electricity records, is the critical factor that could push up still very low gas prices.

But for California, our second highest gas using state, above-average snowpack should provide a stronger hydropower for this summer season relative to 2018.

Combined, Texas and California consume about 25% of U.S. gas, with Texas' use double that of California.

Across the U.S., gas could supply a record 40-43% of U.S. electricity this summer even as the EIA expects solar and wind to be larger sources of generation across the mix

Our gas used for power has increased 35-40% over the past five years, and January power generation also jumped on the year, highlighting broad momentum.

Indeed, U.S. natural gas for electricity has continued to soar, even as overall electricity consumption has trended lower in some years, at nearly 10,700 Bcf last year, a 16% rise from 2017 and easily the highest ever.

Gas is expected to supply 37% of U.S. power this year, even as coal-fired generation saw a brief uptick in 2021 in EIA data, versus 27% just five years ago (see Figure).

Capacity wise, gas is sure to continue to surge its share 45% share of the U.S. power system.

"More than 60% of electric generating capacity installed in 2018 was fueled by natural gas."

We know that natural gas will continue to be the go-to power source: coal and nuclear plants are retiring, and while growing, wind and solar are too intermittent, geography limited, and transmission short to compensate like natural gas can.

"U.S. coal power capacity has fallen by a third since 2010," and last year "16 gigawatts (16,000 MW) of U.S. coal-fired power plants retired."

This year, some 2,000 MW of coal was retired in February alone, with 7,420 MW expected to be closed in 2019.

Ditto for nuclear.

Nuclear retirements this year include Pilgrim, Massachusetts’s only nuclear plant, and Three Mile Island in Pennsylvania.

This will take a combined ~1,600 MW of nuclear capacity offline.

Another 2,500 MW and 4,300 MW of nuclear are expected to be leaving the U.S. power system in 2020 and 2021, respectively.

As more nuclear plants close, EIA projects that net electricity generation from U.S. nuclear power reactors will fall by 17% by 2025.

From 2019-2025 alone, EIA expects U.S. coal capacity to plummet nearly 25% to 176,000 MW, with nuclear falling 15% to 83,000 MW.

In contrast, new combined cycle gas plants will grow capacity almost 30% to around 310,000 MW.

Lower and lower projected commodity prices for gas encourage this immense gas build-out, not to mention non-stop increases in efficiency for gas-based units.

Remember that these are official U.S. Department of Energy estimates, not coming from the industry itself.

In other words, our Department of Energy concludes that gas is the future.

Our hotter and hotter summers are therefore more and more becoming: "summers for natural gas"

Ultimately, this shows why the anti-pipeline movement is so dangerous.

"Affordable Energy Coalition Highlights Ripple Effect of Natural Gas Moratorium."

In April, President Trump signed two executive orders to promote energy infrastructure by directing federal agencies to remove bottlenecks for gas transport into the Northeast in particular, where New England oil-fired generation has spiked, and to streamline federal reviews of border-crossing pipelines and other infrastructure.

Builders, however, are not relying on outside help: all they know is that more U.S. gas demand is a constant, so more infrastructure is mandatory.

They are moving forward diligently: for example, there are now some 27 pipelines worth $33 billion already in the works in Appalachia.

COVID-19 Impact on US Electric Grid: utilities, ERCOT, PJM, and MISO brace for load shifts as remote work rises, industrial demand falls, and nuclear plants enforce pandemic planning to maintain reliability and resilience.

Key Points

Pandemic-driven changes in electricity demand and operations as utilities shift to remote work and reduced industrial use.

✅ Utilities enact remote work and suspend disconnections

✅ Grid operators model load shifts and maintain reliability

✅ Nuclear plants sustain operations with pandemic protocols

Operators of the nation's electric grid and energy companies are bracing for the spread of a virus that is undercutting power demand in countries across Asia and Europe as daily activities grind to a halt.

Owners of U.S. utilities and nuclear plants are canceling events, halting travel, pushing remote work and testing ill workers to slow the spread of the novel coronavirus.

So far, grid operators in the United States say no substantial effect on the electricity demand has emerged, but that could change, even though some reports indicate the U.S. grid is safe for now amid COVID-19. Texas' main grid operator, the Electric Reliability Council of Texas (ERCOT), expressed uncertainty when asked whether it will see changes in demand patterns for power due to the virus.

"It's too early to tell," Leslie Sopko, a spokeswoman for ERCOT, said in an email.

The virus has already taken a toll on power demand overseas. The chairman of Japan's federation of electric utilities and president of Chubu Electric Power Co., Satoru Katsuno, told reporters Friday the country's power demand has weakened as industrial activity slows due to the outbreak, according to Reuters.

The news outlet similarly reported China's industrial power demand this year may decline as the virus curtailed factory output and prevented some employees from returning to work. And, according to Bloomberg, power use in Italy slumped 7.4% last week after the government there shut down schools and told workers to remain home, while Ontario electricity demand also declined as people stayed home.

U.S. utility executives said the sector is well prepared and has faced the threat of spreading infections before. More than a decade ago, global virus scares like SARS pushed companies to hammer out extensive disaster planning, and those have stuck.

"A lot of the foundational work on contingency planning is actually rooted in pandemic planning because of those experiences in the mid-2000s," Scott Aaronson, the Edison Electric Institute's vice president of security and preparedness, told E&E News. "There is a good body of work and a lot of planning and exercises that have gone into being able to operate through these challenges."

Keeping the nation's electric grid running is a top priority at the Department of Energy, said Chris Fall, the agency's point person for COVID-19, which the new coronavirus causes. "Our responsibility is to make sure the electrical grid is resilient and working," said Fall, who directs the department's Office of Science.

He told an agency podcast, called "Direct Current," that the department is working with the private sector and other elements of the energy system. "Obviously we are connected with other agencies like Homeland Security or [the Federal Energy Regulatory Commission] on things like the electrical grid and making sure we have power, and if those people get sick or impacted, we have backups for all of that," he said.

According to a bulletin EEI released on the issue, 40% of a company's employees could be out sick, be quarantined or stay home to care for sick family members. And pandemics may prevent "traditional mutual assistance programs that help companies restore service after natural disasters and weather events," EEI said, such as restoring power in Florida after major storms.

The utility sector is also juggling the needs of its customers. Many major utilities across the nation have vowed to suspend shut-offs and keep power, heat and water on for all customers — a particular concern for people who may be out of work and cannot afford to pay their bills. Companies are also suspending disconnections for nonpayment, some under direction from officials and regulators in states like Ohio and Connecticut, while in Canada Hydro One's peak rate policy has drawn attention among self-isolating customers.

Like other businesses preparing for pandemics, utilities focus on keeping the workforce healthy and operations running. But EEI's Aaronson noted that a key difference with keeping critical infrastructure humming is the possible requirement for the sheltering in place of essential employees who are unable to do their jobs from home, as some operators contemplate locking down key staff at work sites to ensure continuity.

Grid operators are also well-equipped to handle shifts in power demand, and he acknowledged the sector could see changes as more offices and businesses move to remote working. He compared it to the load demand shifts between weekdays and weekends.

"So on the weekends, you're going to have a lot of people at home," Aaronson said. "During the week, it's people in offices. But generally speaking, the ability to have that resiliency and redundancy, the ability to shift resources and the way the grid balances, that is not going to change."

Electricity demand from high-intensity industries like manufacturing or theme parks like Disneyland could also wane, he added, even as electricity inequality in California influences who is most affected.

"It's not just a load shift to the residential, but it's also the load drop in some cases," Aaronson said. "Some of the commercial and industrial customers are going to be working a little bit less than they are presently."

Nuclear plants
Work is continuing at the Plant Vogtle nuclear construction project after Georgia Power Co. announced that one of the site workers is being tested for the coronavirus. The utility does not have the results of that test, a Georgia Power spokesman said late yesterday afternoon. The person works primarily in an office setting and is not on the construction site where two nuclear reactors are being built.

A second worker was tested Saturday, and those results were negative, spokesman John Kraft told E&E News.

Vogtle boasts a high worker count of 9,000 across the entire construction site, which includes office buildings. This is mostly craft laborers, but there are also administrators, executives and Nuclear Regulatory Commission safety inspectors.

A number of contractors and vendors are also on site given the complexity of the project.

Employees who were near the office worker being tested have been sent home until the company receives results. If the test is positive, then those workers will stay home for 14 days, Georgia Power said.

"The company is taking every action to prepare for impacts of the COVID-19 pandemic," Kraft said in a statement. This includes using advice from medical professionals and the Atlanta-based Centers for Disease Control and Prevention.

Georgia Power, owned by Atlanta-based Southern Co., informed regulators at the NRC that a worker was being tested. The federal commission itself has pandemic plans in place to ensure continued oversight, including robust work-from-home capabilities and "social distancing" practices to limit close contact among employees at headquarters.

NRC spokesman Scott Burnell said in an email that telework is not unusual for the agency, and about 75% of its workforce is already equipped to work remotely. The commission tested its telework readiness Friday. Some positions require workers to stay on-site to ensure safe reactor operations, Burnell added.

The nuclear industry has maintained pandemic preparedness plans and procedures since 2006, which have been shared with federal agencies, according to Mary Love, a spokeswoman for the Nuclear Energy Institute. "NEI members are participating in weekly calls to facilitate communications, coordination and best practices," she said.

According to NEI statistics, each plant averages 500 to 1,000 workers. While not every position is essential to operations, some areas like the control room cannot be conducted remotely.

"We know that nuclear power plant operations and the availability of electric service will be tremendously important in minimizing the impact of the situation on the general public," Love added. "We are confident, based on extensive planning, that the industry will continue to operate nuclear plants safely as this event unfolds."

Grid operators
Hundreds of workers responsible for overseeing critical operations of the U.S. electric grid are being encouraged to work from home, their offices are being sanitized, and in-person meetings are being moved online.

PJM Interconnection, the nation's largest grid operator covering some 65 million people across Mid-Atlantic and Midwest states, said Friday a forecast on load changes was not yet available.

PJM has moved all stakeholder meetings online. Employee travel has been suspended, as have external visits to its headquarters in Valley Forge, Pa.

Employees "are equipped to work remotely, if necessary, to maintain business continuity," and PJM "is prepared and able to run and support all market applications from its campus or remotely, as needed," the operator said.

"PJM recognizes that these measures have significant impacts to our staff, members and stakeholders," PJM said on its coronavirus response webpage. "We are dedicated to striking a balance between those impacts and our number one priority — the reliability of the grid."

Still pending at the operator is a decision about its annual meeting in Chicago at the beginning of May. That decision will be made by April 3, PJM said.

The Midcontinent Independent System Operator (MISO), which runs the bulk power grid across 15 states and the Canadian province of Manitoba, is also holding meetings via conference call or online and restricting all business travel.

MISO has encouraged "nonessential" employees to work remotely, leaving only those who actively monitor and manage the operation of the grid working on-site.

The grid operator employs nearly 1,000 people, including 780 at its headquarters in Carmel, Ind.

A board meeting set for the last week of March in New Orleans hasn't yet been canceled, with a final decision on whether to move forward with the meeting expected today.

MISO said it hasn't encountered other changes in normal operations and has not seen significant shifts in electricity demand.

In Texas, ERCOT has about 750 employees, mostly at its campus in the city of Taylor. ERCOT's Sopko said the grid operator is encouraging employees who are not required to be on-site to work from home. The policy is voluntary at this time, but that could change quickly, she said Friday.

ERCOT is also taking extra steps to keep workers safe, including alternating use of facilities, encouraging social distancing and imposing control room measures as part of its pandemic planning, she added.

Energy companies
In the Midwest, utilities including DTE Energy Co., Commonwealth Edison, Consumers Energy and Ameren Corp. said they're following CDC guidance and working with state and local officials to help slow the spread of the virus. That means asking employees who can do their jobs at home to do so, restricting visitors to company offices, canceling large assemblies and nonessential business travel, and holding meetings by phone or online.

Chicago-based ComEd, which serves 4 million customers, is imposing a moratorium on service disconnections and waiving new late payment charges through at least May 1, in addition to working with customers who are facing financial hardships on a case-by-case basis to establish payment arrangements and identify energy assistance options, spokesman Paul Elsberg said.

Many of the Southeast's major energy companies are also curbing travel and encouraging telework, among other steps, in response to the coronavirus.

For Southern Co., this includes its Georgia Power unit; Southern Power; and employees of Southern Company Gas, who are in Illinois, Tennessee and Virginia. Southern has not extended the policies to its Alabama and Mississippi electric companies, spokesman Schuyler Baehman said.

Charlotte, N.C.-based Duke Energy Corp. has suspended all business travel unless workers are traveling by car. The energy giant also is encouraging its employees to rethink their own vacations if upcoming trips take them out of the country.

"Circumstances are changing rapidly around the world," the company said in a statement.

For workers who must come to the office, or work at power plants or on the lines, utilities are doubling down on disinfectant in those areas.

"We're also reminding our employees that we provide a very critical service; we need you well, we need you able," said Le-Ha Anderson, a spokeswoman for Richmond, Va.-based Dominion Energy Inc.

Dominion started asking employees a few weeks ago to take mobile devices home and make sure they have what they need to work remotely. Anyone who has traveled to one of the CDC-identified hot spots is asked to stay home for 14 days with no questions asked, Anderson said.

The federally owned Tennessee Valley Authority has reviewed and updated its plans on how it will operate during a pandemic but has not yet reached the point to have employees telework if they are able to do so.

"We come at this at a very phased approach," TVA spokesman Jim Hopson said. "We can't just shut the doors."

State utility commissions, too, have begun taking steps. In response to a state of emergency declared by Ohio Gov. Mike DeWine (R), the Public Utilities Commission of Ohio on Thursday directed utilities to act where possible to avoid suspending service to customers.

Will Seuffert, executive secretary of the Minnesota Public Utilities Commission, said in an email that the regulator has canceled all public hearings and agenda meetings for the next two weeks and has been supporting telework "throughout the agency" in response to the 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.

Alberta Renewable Energy Market is accelerating as wind and solar prices fall, corporate PPAs expand, and a deregulated, energy-only system, AESO outlooks, and TIER policy drive investment across the province.

Key Points

An open, energy-only Alberta market where wind and solar growth is driven by corporate PPAs, AESO outlooks, and TIER.

✅ Energy-only, deregulated grid enables private investment

✅ Corporate PPAs lower costs and hedge power price risk

✅ AESO forecasts and TIER policy support renewables

By Chris Varcoe, Calgary Herald

A few things are abundantly clear about the state of renewable energy in Alberta today.

First, the demise of Alberta’s Renewable Electricity Program (REP) under the UCP government isn’t going to see new projects come to a screeching halt.

In fact, new developments are already going ahead.

And industry experts believe private-sector companies that increasingly want to purchase wind or solar power are going to become a driving force behind even more projects in Alberta.

BluEarth Renewables CEO Grant Arnold, who spoke Wednesday at the Canadian Wind Energy Association conference, pointed out the sector is poised to keep building in the province, even with the end of the REP program that helped kick-start projects and triggered low power prices.

“The fundamentals here are, I think, quite fantastic — strong resource, which leads to really competitive wind prices . . . it’s now the cheapest form of new energy in the province,” he told the audience.

“Alberta is in a fundamentally good place to grow the wind power market.”

Unlike other provinces, Alberta has an open, deregulated marketplace, which create opportunities for private-sector investment and renewable power developers as well.

The recent decision by the Kenney government to stick with the energy-only market, instead of shifting to a capacity market, is seen as positive for Alberta's energy future by renewable electricity developers.

There is also increasing interest from corporations to buy wind and solar power from generators — a trend that has taken off in the United States with players such as Google, General Motors and Amazon — and that push is now emerging in Canada.

“It’s been really important in the U.S. for unlocking a lot of renewable energy development,” said Sara Hastings-Simon, founding director of the Business Renewable Centre Canada, which seeks to help corporate buyers source renewable energy directly from project developers.

“You have some companies where . . . it’s what their investors and customers are demanding. I think we will see in Alberta customers who see this as a good way to meet their carbon compliance requirements.

“And the third motivation to do it is you can get the power at a good price.”

Just last month, Perimeter Solar signed an agreement with TC Energy to supply the Calgary-based firm with 74 megawatts from its solar project near Claresholm.

More deals in the industry are being discussed, and it’s expected this shift will drive other projects forward.

There is increasing interest from corporations to buy solar and wind energy directly from generators.

“The single-biggest change has been the price of wind and solar,” Arnold said in an interview.

“Alberta looks really, really bright right now because we have an open market. All other provinces, for regulatory reasons, we can’t have this (deal) . . . between a generator and a corporate buyer of power. So Alberta has a great advantage there.”

These forces are emerging as the renewable energy industry has seen dramatic change in recent years in Alberta, with costs dropping and an array of wind and solar developments moving ahead, even as solar expansion faces challenges in the province.

The former NDP government had an aggressive target to see green energy sources make up 30 per cent of all electricity generation by 2030.

Last week, the Alberta Electric System Operator put out its long-term outlook, with its base-case scenario projecting moderate demand growth for power over the next two decades. However, the expected load growth — expanding by an average of 0.9 per cent annually until 2039 — is only half the rate seen in the past 20 years.

Natural gas will become the main generation source in the province as coal-fired power (now comprising more than one-third of generation) is phased out.

Renewable projects initiated under the former NDP government’s REP program will come online in the near term, while “additional unsubsidized renewable generation is expected to develop through competitive market mechanisms and support from corporate power purchase agreements,” the report states.

AESO forecasts installed generation capacity for renewables will almost double to about 19 per cent by 2030, with wind and solar increasing to 21 per cent by 2039.

Another key policy issue for the sector will likely come within the next few weeks when the provincial government introduces details of its new Technology Innovation and Emissions Reduction program (TIER).

The initiative will require large industrial emitters to reduce greenhouse gas emissions to a benchmark level, pay into the technology fund, or buy offsets or credits. The carbon price is expected to be around $20 to $30 a tonne, and the system will kick in on Jan. 1, 2020.

Industry players point out the decision to stick with Alberta’s energy-only market along with the details surrounding TIER, and a focus by government on reducing red tape, should all help the sector attract investment.

“It is pretty clear there is a path forward for renewables here in the province,” said Evan Wilson, regional director with the Canadian Wind Energy Association.

All of these factors are propelling the wind and solar sector forward in the province, at the same time the oil and gas sector faces challenges to grow.

But it doesn’t have to be an either/or choice for the province moving forward. We’re going to need many forms of energy in the coming decades, and Alberta is an energy powerhouse, with potential to develop more wind and solar, as well as oil and natural gas resources.

“What we see sometimes is the politics and discussion around renewables or oil becomes a deliberate attempt to polarize people,” Arnold added.

“What we are trying to show, in working in Alberta on renewable projects, is it doesn’t have to be polarizing. There are a lot of solutions.

“The combination of solutions is part of what we need to talk about.”

Ontario Nuclear Power Costs highlight LCOE, capex, refurbishment outlays, and waste management, compared with renewables, grid reliability, and emissions targets, informing Australia and Peter Dutton on feasibility, timelines, and electricity prices.

Key Points

They include high capex and LCOE from refurbishments and waste, offset by reliable, low-emission baseload.

✅ Refurbishment and maintenance drive lifecycle and LCOE variability.

✅ High capex and long timelines affect consumer electricity prices.

✅ Low emissions, but waste and safety compliance add costs.

Australian opposition leader Peter Dutton recently lauded Canada’s use of nuclear power as a model for Australia’s energy future. His praise comes as part of a broader push to incorporate nuclear energy into Australia’s energy strategy, which he argues could help address the country's energy needs and climate goals. However, the question arises: Is Ontario’s experience with nuclear power as cost-effective as Dutton suggests?

Dutton’s endorsement of Canada’s nuclear power strategy highlights a belief that nuclear energy could provide a stable, low-emission alternative to fossil fuels. He has pointed to Ontario’s substantial reliance on nuclear power, and the province’s exploration of new large-scale nuclear projects, as an example of how such an energy mix might benefit Australia. The province’s energy grid, which integrates a significant amount of nuclear power, is often cited as evidence that nuclear energy can be a viable component of a diversified energy portfolio.

The appeal of nuclear power lies in its ability to generate large amounts of electricity with minimal greenhouse gas emissions. This characteristic aligns with Australia’s climate goals, which emphasize reducing carbon emissions to combat climate change. Dutton’s advocacy for nuclear energy is based on the premise that it can offer a reliable and low-emission option compared to the fluctuating availability of renewable sources like wind and solar.

However, while Dutton’s enthusiasm for the Canadian model reflects its perceived successes, including recent concerns about Ontario’s grid getting dirtier amid supply changes, a closer look at Ontario’s nuclear energy costs raises questions about the financial feasibility of adopting a similar strategy in Australia. Despite the benefits of low emissions, the economic aspects of nuclear power remain complex and multifaceted.

In Ontario, the cost of nuclear power has been a topic of considerable debate. While the province benefits from a stable supply of electricity due to its nuclear plants, studies warn of a growing electricity supply gap in coming years. Ontario’s experience reveals that nuclear power involves significant capital expenditures, including the costs of building reactors, maintaining infrastructure, and ensuring safety standards. These expenses can be substantial and often translate into higher electricity prices for consumers.

The cost of maintaining existing nuclear reactors in Ontario has been a particular concern. Many of these reactors are aging and require costly upgrades and maintenance to continue operating safely and efficiently. These expenses can add to the overall cost of nuclear power, impacting the affordability of electricity for consumers.

Moreover, the development of new nuclear projects, as seen with Bruce C project exploration in Ontario, involves lengthy and expensive construction processes. Building new reactors can take over a decade and requires significant investment. The high initial costs associated with these projects can be a barrier to their economic viability, especially when compared to the rapidly decreasing costs of renewable energy technologies.

In contrast, the cost of renewable energy has been falling steadily, even as debates over nuclear power’s trajectory in Europe continue, making it a more attractive option for many jurisdictions. Solar and wind power, while variable and dependent on weather conditions, have seen dramatic reductions in installation and operational costs. These lower costs can make renewables more competitive compared to nuclear energy, particularly when considering the long-term financial implications.

Dutton’s praise for Ontario’s nuclear power model also overlooks some of the environmental and logistical challenges associated with nuclear energy. While nuclear power generates low emissions during operation, it produces radioactive waste that requires long-term storage solutions. The management of nuclear waste poses significant environmental and safety concerns, as well as additional costs for safe storage and disposal.

Additionally, the potential risks associated with nuclear power, including the possibility of accidents, contribute to the complexity of its adoption. The safety and environmental regulations surrounding nuclear energy are stringent and require continuous oversight, adding to the overall cost of maintaining nuclear facilities.

As Australia contemplates integrating nuclear power into its energy mix, it is crucial to weigh these financial and environmental considerations. While the Canadian model provides valuable insights, the unique context of Australia’s energy landscape, including its existing infrastructure, energy needs, and the costs of scrapping coal-fired electricity in comparable jurisdictions, must be taken into account.

In summary, while Peter Dutton’s endorsement of Canada’s nuclear power model reflects a belief in its potential benefits for Australia’s energy strategy, the cost-effectiveness of Ontario’s nuclear power experience is more nuanced than it may appear. The high capital and maintenance costs associated with nuclear energy, combined with the challenges of managing radioactive waste and ensuring safety, present significant considerations. As Australia evaluates its energy future, a comprehensive analysis of both the benefits and drawbacks of nuclear power will be essential to making informed decisions about its role in the country’s energy strategy.

California Battery Storage is transforming grid reliability as distributed energy, solar-plus-storage, and demand response mitigate rolling blackouts, replace peaker plants, and supply flexible capacity during heat waves and evening peaks across utilities and homes.

Key Points

California Battery Storage uses distributed and utility batteries to stabilize power, shift solar, and curb blackouts.

✅ Supplies flexible capacity during peak demand and heat waves

✅ Enables demand response and replaces gas peaker plants

✅ Aggregated assets form virtual power plants for grid support

Last month as a heat wave slammed California, state regulators sent an email to a group of energy executives pleading for help to keep the lights on statewide. “Please consider this an urgent inquiry on behalf of the state,” the message said.

The manager of the state’s grid was struggling to increase the supply of electricity because power plants had unexpectedly shut down and demand was surging. The imbalance was forcing officials to order rolling blackouts across the state for the first time in nearly two decades.

What was unusual about the emails was whom they were sent to: people who managed thousands of batteries installed at utilities, businesses, government facilities and even homes. California officials were seeking the energy stored in those machines to help bail out a poorly managed grid and reduce the need for blackouts.

Many energy experts have predicted that batteries could turn homes and businesses into mini-power plants that are able to play a critical role in the electricity system. They could soak up excess power from solar panels and wind turbines and provide electricity in the evenings when the sun went down or after wildfires and hurricanes, which have grown more devastating because of climate change in recent years. Over the next decade, the argument went, large rows of batteries owned by utilities could start replacing power plants fueled by natural gas.

But that day appears to be closer than earlier thought, at least in California, which leads the country in energy storage. During the state’s recent electricity crisis, more than 30,000 batteries supplied as much power as a midsize natural gas plant. And experts say the machines, which range in size from large wall-mounted televisions to shipping containers, will become even more important because utilities, businesses and homeowners are investing billions of dollars in such devices.

“People are starting to realize energy storage isn’t just a project or two here or there, it’s a whole new approach to managing power,” said John Zahurancik, chief operating officer at Fluence, which makes large energy storage systems bought by utilities and large businesses. That’s a big difference from a few years ago, he said, when electricity storage was seen as a holy grail — “perfect, but unattainable.”

On Friday, Aug. 14, the first day California ordered rolling blackouts, Stem, an energy company based in the San Francisco Bay Area, delivered 50 megawatts — enough to power 20,000 homes — from batteries it had installed at businesses, local governments and other customers. Some of those devices were at the Orange County Sanitation District, which installed the batteries to reduce emissions by making it less reliant on natural gas when energy use peaks.

John Carrington, Stem’s chief executive, said his company would have provided even more electricity to the grid had it not been for state regulations that, among other things, prevent businesses from selling power from their batteries directly to other companies.

“We could have done two or three times more,” he said.

The California Independent System Operator, which manages about 80 percent of the state’s grid, has blamed the rolling blackouts on a confluence of unfortunate events, including extreme weather impacts on the grid that limited supply: A gas plant abruptly went offline, a lack of wind stilled thousands of turbines, and power plants in other states couldn’t export enough electricity. (On Thursday, the grid manager urged Californians to reduce electricity use over Labor Day weekend because temperatures are expected to be 10 to 20 degrees above normal.)

But in recent weeks it has become clear that California’s grid managers also made mistakes last month, highlighting the challenge of fixing California’s electric grid in real time, that were reminiscent of an energy crisis in 2000 and 2001 when millions of homes went dark and wholesale electricity prices soared.

Grid managers did not contact Gov. Gavin Newsom’s office until moments before it ordered a blackout on Aug. 14. Had it acted sooner, the governor could have called on homeowners and businesses to reduce electricity use, something he did two days later. He could have also called on the State Department of Water Resources to provide electricity from its hydroelectric plants.

Weather forecasters had warned about the heat wave for days. The agency could have developed a plan to harness the electricity in numerous batteries across the state that largely sat idle while grid managers and large utilities such as Pacific Gas & Electric scrounged around for more electricity.

That search culminated in frantic last-minute pleas from the California Public Utilities Commission to the California Solar and Storage Association. The commission asked the group to get its members to discharge batteries they managed for customers like the sanitation department into the grid. (Businesses and homeowners typically buy batteries with solar panels from companies like Stem and Sunrun, which manage the systems for their customers.)

“They were texting and emailing and calling us: ‘We need all of your battery customers giving us power,’” said Bernadette Del Chiaro, executive director of the solar and storage association. “It was in a very last-minute, herky-jerky way.”

At the time of blackouts on Aug. 14, battery power to the electric grid climbed to a peak of about 147 megawatts, illustrating how virtual power plants can rapidly scale, according to data from California I.S.O. After officials asked for more power the next day, that supply shot up to as much as 310 megawatts.

Had grid managers and regulators done a better job coordinating with battery managers, the devices could have supplied as much as 530 megawatts, Ms. Del Chiaro said. That supply would have exceeded the amount of electricity the grid lost when the natural gas plant, which grid managers have refused to identify, went offline.

Officials at California I.S.O. and the public utilities commission said they were working to determine the “root causes” of the crisis after the governor requested an investigation.

Grid managers and state officials have previously endorsed the use of batteries, using AI to adapt as they integrate them at scale. The utilities commission last week approved a proposal by Southern California Edison, which serves five million customers, to add 770 megawatts of energy storage in the second half of 2021, more than doubling its battery capacity.

And Mr. Zahurancik’s company, Fluence, is building a 400 megawatt-hour battery system at the site of an older natural gas power plant at the Alamitos Energy Center in Long Beach. Regulators this week also approved a plan to extend the life of the power plant, which was scheduled to close at the end of the year, to support the grid.

But regulations have been slow to catch up with the rapidly developing battery technology.

Regulators and utilities have not answered many of the legal and logistical questions that have limited how batteries owned by homeowners and businesses are used. How should battery owners be compensated for the electricity they provide to the grid? Can grid managers or utilities force batteries to discharge even if homeowners or businesses want to keep them charged up for their own use during blackouts?

During the recent blackouts, Ms. Del Chiaro said, commercial and industrial battery owners like Stem’s customers were compensated at the rates similar to those that are paid to businesses to not use power during periods of high electricity demand. But residential customers were not paid and acted “altruistically,” she said.
