India, U.S. to draft plan to implement nuclear deal

Canadian Hydropower Transmission delivers HVDC clean energy via New England Clean Energy Connect and Champlain Hudson Power Express, linking HydroQuébec to Maine and New York grids for renewable energy, decarbonization, and lower wholesale electricity rates.

Key Points

HVDC delivery of HydroQuébec power to New England and New York via NECEC and CHPE, cutting emissions and costs.

✅ 1,200 MW via NECEC; 1,000 MW via CHPE.

✅ HVDC routes: 145-mile NECEC and 333-mile CHPE.

✅ Debates: land impacts, climate justice, wholesale rates.

As the sole residents of unorganized territory T5 R7 deep within Maine's North Woods, Duane Hanson and his wife, Sally Kwan, have watched the land around them—known for its natural beauty, diverse wildlife and recreational fishing—transformed by decades of development. 

But what troubles them most is what could happen in the next few months. State and corporate officials are pushing for construction of a 53-mile-long power line corridor cutting right through the woods and abutting the wild lands surrounding Hanson's property. 

If its proponents succeed, Hanson fears the corridor may represent the beginning of the end of his ability to live "off the land" away from the noise of technology-obsessed modern society. Soon, that noise may be in his backyard. 

"I moved here to be in the pristine wilderness," said Hanson.
 
With his life in what he considers the last "wild" place left on the East Coast on the line, the stakes have never felt higher to Hanson—and many across New England, as well.

The corridor is part of the New England Clean Energy Connect, one of two major and highly controversial transmission line projects meant to deliver Canadian hydropower from the government-owned utility HydroQuébec, in a province that has closed the door on nuclear power, to New England electricity consumers. 

As New England states rush to green their electric grids and combat the accelerating climate crisis, the simultaneous push from Canada to expand the market for hydroelectric power from its vast water resources, including Manitoba's clean energy, has offered these states a critical lifeline at just the right moment. 

The other big hydropower transmission line project will deliver 1,000 megawatts of power, or enough to serve approximately one million residential customers, to the New York City metropolitan area, which includes the city, Long Island, and parts of the Hudson Valley, New Jersey, Connecticut and Pennsylvania. 

The 333-mile-long Champlain Hudson Power Express project will consist of two high voltage direct current cables running underground and underwater from Canada, beneath Lake Champlain and the Hudson River, to Astoria, Queens. 

There, the Champlain Hudson project will interconnect to a sector of the New York electricity grid where city and corporate officials say the hydropower supplied can help reduce the fossil fuels that currently comprise significantly more of the base load than in other parts of the state. Though New York has yet to finalize a contract with HydroQuébec over its hydropower purchase, developers plan to start construction on the $2.2 billion project in 2021 and say it will be operational in 2025. 

The New England project consists of 145 miles of new HVDC transmission line that will run largely above ground from the Canadian border, through Maine to Massachusetts. The $1 billion project, funded by Massachusetts electricity consumers, is expected to deliver 1,200 megawatts of clean energy to the New England energy grid, becoming the region's largest clean energy source. 

Central Maine Power, which will construct the Maine transmission corridor, says the project will decrease wholesale electric rates and create thousands of jobs. Company officials expect to receive all necessary permits and begin construction by the year's end, with the project completed and in service by 2020. 

With only months until developers start making both projects on-the-ground realities, they have seized public attention within, and beyond, their regions. 

Hanson is one among many concerned New England and New York residents who've joined the ranks of environmental activists in a contentious battle with public and corporate officials over the place of Canadian hydropower in their states' clean energy futures. 

Officials and transmission line proponents say importing Canadian hydropower offers an immediate and feasible way to help decarbonize electricity portfolios in New York and New England and to address existing transmission constraints that limit cross-border flows today, supporting their broader efforts to combat climate change. 

But some environmental activists say hydropower has a significant carbon footprint of its own. They fear the projects will make states look "greener" at the expense of the local environment, Indigenous communities, and ultimately, the climate. 

"We're talking about the most environmentally and economically just pathway" to decarbonization, said Annel Hernandez, associate director of the NYC Environmental Justice Alliance. "Canadian hydro is not going to provide that." 

To that end, environmental groups opposing Canadian hydropower say New York and New England should seize the moment to expedite local development of wind and solar power. 

Paul Gallay, president of the nonprofit environmental organization Riverkeeper—which withdrew its initial support for the Champlain Hudson Power Express last November— believes New York has the capacity to develop enough in-state renewable energy sources to meet its clean energy goals, without the new transmission line. 

Yet New York City's analysis shows clearly that Canadian hydropower is critical for its clean energy strategy, said Dan Zarrilli, director of OneNYC and New York City's chief climate policy adviser. 

"We need every bit of clean energy we can get our hands on," he said, to meet the city's goal of carbon neutrality by 2050 and help achieve the state's clean energy mandates. 

Removing Canadian hydropower from the equation, said Zarilli, would commit the city to the "unacceptable outcome" of burning more gas. The city's marginalized communities would likely suffer most from the resulting air pollution and associated health impacts. 

While the two camps debate Canadian hydropower's carbon footprint and what climate justice requires, this much is clear: When it comes to pursuing a zero-carbon future, there are no easy answers. 

Hydropower's Carbon Footprint
Many people take for granted that because hydropower production doesn't involve burning fossil fuels, it's a carbon-neutral endeavor. But that's not always the case, depending on where hydropower is sourced. 

Large-scale hydropower projects often involve the creation of hydroelectric dams and reservoirs, and, in some cases, repowering existing dams to generate clean electricity. The release and flow of water from the reservoir through the dam provides the energy necessary to generate hydropower, which long-distance power lines, or transmission lines, carry to its intended destination—in this case, New England and New York. 

The initial process of flooding land to create a hydroelectric reservoir can have a sizable carbon footprint, especially in heavily vegetated areas. It causes the vegetation and soil underwater to decompose, releasing carbon dioxide and methane—a greenhouse gas 84 times more potent over a 20-year period than carbon dioxide. 

Hydropower accounts for 60 percent of Canada's electricity generation, and HydroQuébec has planned to increase capacity to 37,000 MW in 2021, with the nation second only to China in the percentage of the world's total hydroelectricity it generates. By contrast, hydropower only accounts for seven percent of U.S. utility-scale electricity generation, making it a foreign concept to many Americans. 

As New England works to introduce substantial amounts of Canadian hydropower to its electricity grid, hydropower proponents are promoting it as a prime source for clean electricity, and new NB Power agreements are expanding regional transfers within Canada as well. 

Last fall, Central Maine Power formed its own political action committee, Clean Energy Matters, to advance the New England hydropower project. Together with HydroQuébec, the Maine utility has spent nearly $17 million campaigning for the project this year.

US Grid Pandemic Response coordinates control rooms, grid operators, and critical infrastructure, leveraging hydroelectric plants, backup control centers, mutual assistance networks, and deep cleaning protocols to maintain reliability amid reduced demand and COVID-19 risks.

Key Points

US Grid Pandemic Response encompasses measures by utilities and operators to safeguard power reliability during COVID-19

✅ Control rooms staffed on-site; operators split across backup centers

✅ Health screenings, deep cleaning, and isolation protocols mitigate contagion

✅ Reduced demand and mutual assistance improve grid resilience

Control rooms are the brains of NYPA’s power plants, which are mostly hydroelectric and supply about a quarter of all the electricity in New York state. They’re also a bit like human petri dishes. The control rooms are small, covered with frequently touched switches and surfaces, and occupied for hours on end by a half-dozen employees. Since social distancing and telecommuting isn’t an option in this context, NYPA has instituted regular health screenings and deep cleanings to keep the coronavirus out.

The problem is that each power plant relies on only a handful of control room operators. Since they have a specialized skill set, they can’t be easily replaced if they get sick. “They are very, very critical,” says Gil Quiniones, NYPA president and CEO. If the pandemic worsens, Quiniones says that NYPA may require control room operators to live on-site at power plants to reduce the chance of the virus making it in from the outside world. It sounds drastic, but Quiniones says NYPA has done it before during emergencies—once during the massive 2003 blackout, and again during Hurricane Sandy.

Meanwhile, PJM is one of North America’s nine regional grid operators and manages the transmission lines that move electricity from power plants to millions of customers in 13 states on the Eastern seaboard, including Washington, DC. PJM has had a pandemic response plan on the books for 15 years, but Mike Bryson, senior vice president of operations, says that this is the first time it’s gone into full effect. As of last week, about 80 percent of PJM’s 750 full-time employees have been working from home. But PJM also requires a skeleton crew of essential workers to be on-site at all times in its control centers. As part of its emergency planning, PJM built a backup control center years ago, and now it is splitting control center operators between the two to limit contact.

Past experience with large-scale disasters has helped the energy sector keep the lights on and ventilators running during the pandemic. Energy is one of 16 sectors that the US government has designated as “critical infrastructure,” which also includes the communications industry, transportation sector, and food and water systems. Each is seen as vital to the country and therefore has a duty to maintain operations during national emergencies.

“We need to be treated as first responders,” says Scott Aaronson, the vice president of security and preparedness at the Edison Electric Institute, a trade group representing private utilities. “Everybody's goal right now is to keep the public healthy, and to keep society functioning as best we can. A lack of electricity will certainly create a challenge for those goals.”

America’s electricity grid is a patchwork of regional grid operators connecting private and state-owned utilities. This means simply figuring out who’s in charge and coordinating among the various organizations is one of the biggest challenges to keeping the electricity flowing during a national emergency, according to Aaronson.

Generally, a lot of this responsibility falls on formal energy organizations like the nonprofit North American Electric Reliability Corporation and the Federal Energy Regulatory Commission. But during the coronavirus outbreak, an obscure organization run by the CEOs of electric utilities called the Electricity Subsector Coordinating Council has also served as a primary liaison between the federal government and the thousands of utility companies around the US. Aaronson says the organization has been meeting twice a week for the past three weeks to ensure that utilities are implementing best practices in their response to the coronavirus, as well as to inform the government of material needs to keep the energy sector running smoothly.

This tight-knit coordination will be especially important if the pandemic gets worse, as many forecasts suggest it will. Most utilities belong to at least one mutual assistance group, an informal network of electricity suppliers that help each other out during a catastrophe. These mutual assistance networks are usually called upon following major storms that threaten prolonged outages. But they could, in principle, be used to help during the coronavirus pandemic too. For example, if a utility finds itself without enough operators to manage a power plant, it could conceivably borrow trained operators from another company to make sure the power plant stays online.

So far, utilities and grid operators have managed to make it work on their own. There have been a handful of coronavirus cases reported at power plants, but they haven’t yet affected these plants’ ability to deliver energy. The challenges of running a power plant with a skeleton crew is partially offset by the reduced power demand as businesses shut down and more people work from home, says Robert Hebner, the director of the Center for Electromechanics at the University of Texas. “The reduced demand for power gives utilities a little breathing room,” says Hebner.

A recent study by the University of Chicago’s Energy Policy Institute found that electricity demand in Italy has plunged by 18 percent following the severe increase in coronavirus cases in the country. Energy demand in China also plummeted as a result of the pandemic. Bryson, at PJM, says the grid operator has seen about a 6 percent decrease in electricity demand in recent weeks, but expects an even greater drop if the pandemic gets worse.

Generally speaking, problems delivering electricity in the US occur when the grid is overloaded or physically damaged, such as during California wildfires or a hurricane.

An open question among coronavirus researchers is whether there will be a second wave of the pandemic later this year. During the Spanish flu pandemic in the early 20th century, the second wave turned out to be deadlier than the first. If the coronavirus remerges later this year, it could be a serious threat to reliable electricity in the US, says John MacWilliams, a former associate deputy secretary of the Department of Energy and a senior fellow at Columbia University’s Center on Global Energy Policy.

“If this crisis extends into the fall, we're going to hit hurricane season along the coasts,” MacWilliams says. “Utilities are doing a very good job right now, but if we get unlucky and have an active hurricane season, they're going to get very stressed because the number of workers that are available to repair damage and restore power will become more limited.”

This was a sentiment echoed by Bryson at PJM. “Any one disaster is manageable, but when you start layering them on top of each other, it gets much more challenging,” he adds. The US electricity grid struggles to handle major storms as it is, and these challenges will be heightened if too many workers are home sick. In this sense, the energy sector’s ability to deliver the electricity needed to keep manufacturing medical supplies or keep ventilators running depends to a large extent on our ability to flatten the curve today. The coronavirus is bad enough without having to worry about the lights going out.

Duke Energy's $56 billion capital investment plan will deliver significant customer benefits and create jobs at a time when policymakers at all levels are looking for ways to rebuild the economy in 2020 and beyond. These investments will deliver cleaner energy for customers and communities while enhancing the energy grid to provide greater reliability and resiliency.

"Sustainability and the reduction of carbon emissions are closely tied to our region's success," said Lynn Good, Duke Energy Chair, President and CEO. "In our recent Climate Report, we shared a vision of a cleaner electricity future with an increasing focus on renewables and battery storage in addition to a diverse mix of zero-carbon nuclear, natural gas, hydro and energy efficiency programs.

"Achieving this clean energy vision will require all of us working together to develop a plan that is smart, equitable and ensures the reliability and affordability that will spur economic growth in the region. While we're disappointed that we're not able to move forward with ACP, we will continue exploring ways to help our customers and communities, particularly in eastern North Carolina where the need is great," said Good.

Already a clean-energy leader, Duke Energy has reduced its carbon emissions by 39% from 2005 and remains on track to cut its carbon emissions by at least 50% by 2030, as peers like Alliant's carbon-neutral plan demonstrate broader industry momentum toward decarbonization. The company also has an ambitious clean energy goal of reaching net-zero emissions from electricity generation by 2050. 

In September 2020, Duke Energy plans to file its Integrated Resource Plans (IRP) for the Carolinas after an extensive process of working with the state's leaders, policymakers, customers and other stakeholders. The IRPs will include multiple scenarios to support a path to a cleaner energy future in the Carolinas, reflecting key utility trends shaping resource planning.

Since 2010, Duke Energy has retired 51 coal units totaling more than 6,500 megawatts (MW) and plans to retire at least an additional 900 MW by the end of 2024. In 2019, the company proposed to shorten the book lives of another approximately 7,700 MW of coal capacity in North Carolina and Indiana.

Duke Energy will host an analyst call in early August 2020 to discuss second quarter 2020 financial results and other business and financial updates. The company will also host its inaugural Environmental, Social and Governance (ESG) investor day in October 2020.

Brazil Energy Emergency Loan Package aims to bolster utilities via BNDES as coronavirus curbs electricity demand. Aneel and the Mines and Energy Ministry weigh measures while Eletrobras privatization and auctions face delays.

Key Points

An emergency plan supporting Brazilian utilities via BNDES and banks during coronavirus demand slumps and payment risks.

✅ Modeled on 2014-2015 sector loans via BNDES and private banks

✅ Addresses cash flow from lower demand and bill nonpayment

✅ Auctions and Eletrobras privatization delayed amid outbreak

Brazil’s government is considering an emergency loan package for energy distributors struggling with lower energy use and facing lost revenues because of the coronavirus outbreak, echoing strains seen elsewhere such as Germany's utility troubles during the energy crisis, an industry group told Reuters.

Marcos Madureira, president of Brazilian energy distributors association Abradee, said the package being negotiated by companies and the government could involve loans from state development bank BNDES or a pool of banks, but that the value of the loans and other details was not yet settled.

Also, Brazil’s Mines and Energy Ministry is indefinitely postponing projects to auction off energy transmission and generation assets planned for this year because of the coronavirus, even as the need for electricity during COVID-19 remained critical, it said in the Official Gazette.

The coronavirus outbreak will also delay the privatization of state-owned utility Eletrobras, its chief executive officer said on Monday.

The potential loan package under discussion would resemble a similar measure in 2014 and 2015 that offered about 22 billion reais ($4.2 billion) in loans to the sector as Brazil was entering its deepest recession on record, and drawing comparisons to a proposed Texas market bailout after a winter storm, Madureira said.

Public and private banks including BNDES, Caixa Economica Federal, Itau Unibanco and Banco Bradesco participated in those loans.

Three sources involved in the discussions said on condition of anonymity that the Mines and Energy Ministry and energy regulator Aneel were considering the matter.

Aneel declined to comment. The Mines and Energy Ministry and BNDES did not immediately respond to requests for comment.

Energy distributors worry that reduced electricity demand during COVID-19 could result in deep revenue losses.

The coronavirus has led to widespread lockdowns of non-essential businesses in Brazil, while citizens are being told to stay home. That is causing lost income for many hourly and informal workers in Brazil, who could be unable to pay their electricity bills, raising risks of pandemic power shut-offs for vulnerable households.

The government sees a loan package as a way to stave off a potential chain of defaults in the sector, a move discussed alongside measures such as a Brazil tax strategy on energy prices, one of the sources said.

On a conference call with investors about the company’s latest earnings, Eletrobras CEO Wilson Ferreira Jr. said privatization would be delayed, without giving any more details on the projected time scale.

The largest investors in Brazil’s energy distribution sector include Italy’s Enel, Spain’s Iberdrola via its subsidiary Neoenergia and China’s State Grid via CPFL Energia, with Chinese interest also evidenced by CTG's bid for EDP, as well as local players Energisa e Equatorial Energia.

California Heatwave Power Crisis strains CAISO as record demand triggers emergency alerts, demand response, and rolling blackout warnings. PG&E prepares outages while solar fades at peak, drought cuts hydropower, and reliability hinges on conservation.

Key Points

Extreme heat driving record demand in California, straining CAISO and prompting conservation to avert rolling blackouts.

✅ CAISO hit a record 52 GW peak load amid triple-digit heat

✅ Emergency alerts spurred demand response, cutting load spikes

✅ Solar drop and drought-weakened hydro worsened evening shortfall

California narrowly avoided blackouts for a second successive day even as blistering temperatures pushed electricity demand to a record and stretched the state’s power grid close to its limits.

The state imposed its highest level of energy emergency for several hours late Tuesday and urged consumers to turn off lights, curb air conditioners and shut off power-hungry appliances after a day of extraordinary stress on electricity infrastructure as temperatures in many regions topped 110 degrees Fahrenheit (43 Celsius).

Electricity use had reached 52 gigawatts Tuesday, easily breaking a record that stood since 2006, according to the California Independent System Operator. The state issued emergency alerts direct to cell phones in several counties asking for immediate power conservation, and grid data show that demand plunged in response. Emergency measures were finally lifted at about 9 p.m. local time.

Much of California remains under an excessive heat warning through Friday, with authorities already preparing for more severe pressure on the power system on Wednesday amid a looming supply shortage across the grid. “We aren’t out of the woods yet,” Governor Gavin Newsom said in a message posted on his office’s Twitter account. “We will see continued extreme temps this week and if we rallied today, we can do it again.”

The state’s largest power company, PG&E Corp. said earlier Tuesday that it had notified about 525,000 homes and businesses that they could lose power for up to two hours. That warning came as temperatures in downtown Sacramento hit 116 degrees Fahrenheit, topping a previous 1925 record.

Newsom earlier signed an executive order extending until Friday emergency measures to free up additional power supplies, rather than allowing them to expire as planned on Wednesday. Many state buildings were ordered to power down lights and air conditioning at 4 p.m., and he urged residents and businesses to conserve the equivalent of 3 gigawatts of power in order to stave off blackouts. 

California's Early Brush With Blackouts Bodes Ill For Days Ahead

California faced a similar energy emergency Monday, which was alleviated in part by activating temporary gas-fired power plants operated by the California Department of Water Resources. The current heat wave, which began in the last week of August, is remarkable in both its ferocity and duration, according to officials. 

The prospect of outages underscores how grids have become vulnerable in the face of extreme weather as California transitions from fossil fuels to renewable energy, an approach it is increasingly exporting to Western states as well. California's climate policies have aggressively closed natural-gas power plants in recent years, leaving the state increasingly dependent on solar farms that go dark late in the day just as electricity demand peaks. At the same time, the state is enduring the Southwest’s worst drought in 1,200 years, sapping hydropower production.

The average 15-minute wholesale power price in Caiso surged to $1,806 a megawatt-hour at 4:45 p.m. local time, according to the grid operator’s website.

Average day-ahead prices top $300 a megawatt-hour in Southern California
  
A break from the heat will come across Southern California later this week, thanks to Tropical Storm Kay in the Pacific Ocean, according to weather officials. Kay is forecast to edge up the coastline of Mexico’s Baja California peninsula. As it moves north, the storm will pump moisture and clouds into Southern California and Arizona, taking an edge off the heat.

Electricity Security and Firm Capacity underpin reliable supply, balancing variable renewables with grid flexibility via gas plants, nuclear power, hydropower, battery storage, and demand response, safeguarding telework, e-commerce, and critical healthcare operations.

Key Points

Ability to meet demand by combining firm generation and flexible resources, keeping grids stable as renewables grow.

✅ Balances variable renewables with dispatchable generation

✅ Rewards flexibility via capacity markets and ancillary services

✅ Enhances grid stability for critical loads during low demand

The huge disruption caused by the coronavirus crisis, and the low-carbon electricity lessons drawn from it, has highlighted how much modern societies rely on electricity and how firm capacity, such as that provided by nuclear power, is a crucial element in ensuring supply, International Energy Agency (IEA) Executive Director Fatih Birol said.

In a commentary posted on LinkedIn, Birol said: "The coronavirus crisis reminds us of electricity's indispensable role in our lives. It's also providing insights into how that role is set to expand and evolve in the years and decades ahead."

Reliable electricity supply is crucial for teleworking, e-commerce, operating ventilators and other medical equipment, among all its other uses, he said, adding that the hundreds of millions of people who live without any access to electricity are far more vulnerable to disease and other dangers.

"Although new forms of short-term flexibility such as battery storage are on the rise, and initiatives like UK home virtual power plants are emerging, most electricity systems rely on natural gas power plants - which can quickly ramp generation up or down at short notice - to provide flexibility, underlining the critical role of gas in clean energy transitions," Birol said.

"Today, most gas power plants lose money if they are used only from time to time to help the system adjust to shifts in demand. The lower levels of electricity demand during the current crisis are adding to these pressures. Hydropower, an often forgotten workhorse of electricity generation, remains an essential source of flexibility.

"Firm capacity, including nuclear power in countries that have chosen to retain it as an option, is a crucial element in ensuring a secure electricity supply even as soaring electricity and coal use complicate transitions. Policy makers need to design markets that reward different sources for their contributions to electricity security, which can enable them to establish viable business models."

In most economies that have taken strong confinement measures in response to the coronavirus - and for which the IEA has available data - electricity demand has declined by around 15%, largely as a result of factories and businesses halting operations, and in New York City load patterns were notably reshaped during lockdowns. If electricity demand falls quickly while weather conditions remain the same, the share of variable renewables like wind and solar can become higher than normal, and low-emissions sources are set to cover almost all near-term growth.

"With weaker electricity demand, power generation capacity is abundant. However, electricity system operators have to constantly balance demand and supply in real time. People typically think of power outages as happening when surging electricity demand overwhelms supply. But in fact, some of the most high-profile blackouts in recent times took place during periods of low demand," Birol said.

"When electricity from wind and solar is satisfying the majority of demand, and renewables poised to eclipse coal by 2025 are reshaping the mix, systems need to maintain flexibility in order to be able to ramp up other sources of generation quickly when the pattern of supply shifts, such as when the sun sets. A very high share of wind and solar in a given moment also makes the maintenance of grid stability more challenging."
