CanadaÂ’s former nuclear watchdog is seeking a judicial review into her firing by the Conservative government resulting from the shutdown of a nuclear research reactor.

Linda Keen, a long-time bureaucrat, had angered Prime Minister Stephen Harper with her handling of the Chalk River reactor shutdown that left the Conservative government scrambling and embarrassed as it coped with the shortage of medical isotopes.

The motion, submitted to the Federal Court, is the latest development in the bitter dispute between Keen and the Conservatives. She was fired as president of the Canadian Nuclear Safety Commission (CNSC) when she wouldnÂ’t okay the start-up of the aging Chalk River reactor.

“By this application for judicial review, Ms. Keen is asking the Federal Court to declare that she was unlawfully removed as president and that the November 2005 Order in Council, which reappointed her as president, remains in full force and effect,” said Ottawa lawyer Allan O’Brien.

Keen, who remains on the CNSC board, recently told ParliamentÂ’s natural resources committee that it is not the job of a nuclear regulator to ensure the production of isotopes but rather that the public is protected from nuclear accidents.

The reactor was voluntarily taken out of service by Atomic Energy Canada Ltd. because of ongoing safety concerns.

The Harper government brought in emergency legislation to override KeenÂ’s safety warnings and restart the reactor in mid-December. The CNSC is an independent quasi-judicial body meant to work at armÂ’s length from the government.

It was a month later that Natural Resources Minister Gary Lunn told Keen that the government had lost confidence in her, but when he appeared before the committee he could not cite one reason for the decision to dump Keen, who was to serve as president until 2010.

The Chalk River reactor, run by Atomic Energy of Canada Ltd., was shut down on Nov. 18 for routine maintenance, but an inspection by the regulatory staff found that mandatory safety upgrades – connecting vital cooling pumps to an emergency power supply that would work even if the area was hit with an earthquake – had not been done.

Maritime Link almost a reality, as first power cable reaches Nova Scotia

Maritime Link Subsea Cable enables HVDC grid interconnection across the Cabot Strait, linking Nova Scotia with Newfoundland and Labrador to import Muskrat Falls hydroelectric power and expand renewable energy integration and reliability.

 

Key Points

A 170-km HVDC subsea link connecting Nova Scotia and Newfoundland and Labrador for Muskrat Falls power and renewables

✅ 170-km HVDC subsea route across Cabot Strait

✅ Connects Nova Scotia and Newfoundland and Labrador grids

✅ Enables Muskrat Falls hydro and renewable energy trade

 

The longest sub-sea electricity cable in North America now connects Nova Scotia and Newfoundland and Labrador, according to the company behind the $1.7-billion Maritime Link project.  

The first of the project's two high-voltage power transmission cables was anchored at Point Aconi, N.S., on Sunday. 

The 170-kilometre long cable across the Cabot Strait will connect the power grids in the two provinces. The link will allow power to flow between the two provinces, as demonstrated by its first electricity transfer milestone, and bring to Nova Scotia electricity generated by the massive Muskrat Falls hydroelectric project in Labrador. 

Ultimately, the Maritime Link will help Nova Scotia reach the renewable energy goals set out by the federal government, said Rick Janega, the president and CEO of Emera Newfoundland and Labrador, whose subsidiary owns the Maritime Link.

"If not for the Maritime Link then really the province would not have the ability to meet those requirements because we're pretty much tapped out of all the hydro in province and all the wind generation without creating new interconnections like the Maritime Link," said Janega. 

Not everyone wanted the link 

Fishermen in Cape Breton had objected to the Maritime Link. They were concerned about how the undersea cable might affect fish in the area. 

The laying of the cable and other construction closed a three-kilometre long and 600-metre wide swath of ocean bottom to fishermen for the entire 2017 lobster season.  

But the company came to an agreement to compensate a group of 60 Cape Breton lobster and crab fishermen affected by the project this season. The terms of the compensation deal were not released. 

 

Long cable, big job

The transmission cable runs northwest of the Marine Atlantic ferry route between North Sydney, N.S., and Port aux Basques, N.L. 

Installation of the second cable is set to begin in June, a major step comparable to BC Hydro's Site C transmission milestone achieved recently. The entire link should be completed by late 2017 and should go into full service by January 2018.

"We're quite confident as soon as the Maritime Link is in service there will be energy transactions between Nova Scotia Power and Newfoundland Hydro. Both utilities have already identified opportunities to save money and exchange energy between the two provinces," said Janega.

That's two years before power is expected to flow from the Muskrat Falls hydro project. The Labrador-based power generating facility has been hampered by delays.

Those kinds of transmission project delays are expected for such a large project, said Janega, and won't stop the Maritime Link from being used. 

"With the Maritime Link going in service this year providing Nova Scotia the opportunity that it needs to be able to reach carbon reductions and to adapt to climate change and to increase renewable energy content and we're very pleased to be at this state today," said Janega.

IVECO BUS is making significant strides in the French public transportation sector, recently securing contracts for the delivery of hydrogen and battery electric buses. This development underscores the growing commitment of cities and regions in France to transition to cleaner, more sustainable public transportation options, even as electric bus adoption challenges persist. With these new contracts, IVECO BUS is poised to strengthen its position as a leader in the electric mobility market.

Expanding the Green Bus Fleet

The contracts involve the supply of various models of IVECO's hydrogen and electric buses, highlighting a strategic shift towards sustainable transport solutions. France has been proactive in its efforts to reduce carbon emissions and promote environmentally friendly transportation. As part of this initiative, many local authorities are investing in clean bus fleets, which has opened up substantial opportunities for manufacturers like IVECO.

These contracts will provide multiple French cities with advanced vehicles designed to minimize environmental impact while maintaining high performance and passenger comfort. The move towards hydrogen and battery electric buses reflects a broader trend in public transportation, where cities are increasingly adopting green technologies, with lessons from TTC's electric bus fleet informing best practices to meet both regulatory requirements and public demand for cleaner air.

The Role of Hydrogen and Battery Electric Technology

Hydrogen and battery electric buses represent two key technologies in the transition to sustainable transport. Battery electric buses are known for their zero tailpipe emissions, making them ideal for urban environments where air quality is a pressing concern, as demonstrated by the TTC battery-electric rollout in North America.

Electricity is civilization": Winter looms over Ukraine battlefront

Ukraine Power Grid Restoration accelerates across liberated Kharkiv, restoring electricity, heat, and water amid missile and drone strikes, demining operations, blackouts, and winterization efforts, showcasing resilience, emergency repairs, and critical infrastructure recovery.

 

Key Points

Ukraine's rapid push to repair war-damaged grids, restore heat and water, and stabilize key services before winter.

✅ Priority repairs restore electricity and water in liberated Kharkiv.

✅ Crews de-mine lines and work under shelling, drones, and missiles.

✅ Winterization adds generators, mobile stoves, and large firewood supplies.

 

On the freshly liberated battlefields of northeast Ukraine, a pile of smashed glass windows outside one Soviet-era block of apartments attests to the violence of six months of Russian occupation, and of Ukraine’s sweeping recent military advances.

Indoors, in cramped apartments, residents lived in the dark for weeks on end.

Now, with a hard winter looming, they marvel at the speed and urgency with which Ukrainian officials have restored another key ingredient to their survival: electric power, a critical effort to keep the lights on this winter across communities.

Among those things governments strive to provide are security, opportunity, and minimal comfort. With winter approaching, and Russia targeting Ukraine’s infrastructure, add to that list heat and light, even as Russia hammers power plants nationwide. It’s requiring a concerted effort.

“Thank God it works! Electricity is civilization – it is everything,” says Antonina Krasnokutska, a retired medical worker, looking affectionately at the lightbulb that came on the day before, and now burns again in her tiny spotless kitchen.

“Without electricity there is no TV, no news, no clothes washing, no charging the phone,” says Ms. Krasnokutska, her gray hair pulled back and a small crucifix around her neck.

“Before, it was like living in the Stone Age,” says her grown son, Serhii Krasnokutskyi, who is more than a head taller. “As soon as it got dark, everyone would go to sleep.”

He shows a picture on his phone from a few days earlier, of a tangle of phone and computer charging cables – including his – plugged in at a local shop with a generator.

“We are very grateful for the people who repaired this electricity, even with shelling continuing,” he says. “They have a very complicated job.”

Indeed, although a lack of power might have been a novel inconvenience during the warm summer season, it increasingly has become a matter of great urgency for Ukrainian citizens and officials.

Coping through Ukraine’s winter with dignity and any degree of security will require courage and perseverance, as the severity and suffering that the season can bring here are being weaponized by Russia, as it seeks to compensate for a string of battlefield losses.

In recent days, Russian attacks have specifically targeted Ukraine’s electrical and other civilian infrastructure – all with the apparent aim of making this winter as hard as possible for Ukrainians, even as Moscow employs other measures to spread the hardship across Europe, while Ukraine helps Spain amid blackouts through grid support.

Ukrainian President Volodymyr Zelenskyy said Monday that Russian barrages across the country with missiles and Iran-supplied kamikaze drones had destroyed 30% of Ukraine’s power stations in the previous eight days, including strikes on western Ukraine that caused outages. Thousands of towns have been left without electricity.

Kharkiv’s challenges
Emblematic of the national challenge is the one facing officials in the northeast Kharkiv region, where Ukraine recaptured more than 3,000 square miles in a September counteroffensive. Ukrainian forces are still making gains on that front, as well as in the south toward Kherson, where Wednesday Russia started evacuating civilians from the first major city it occupied, after launching its three-pronged invasion last February.

Across the Kharkiv region, Ukrainians are stockpiling as much wood, fuel, and food as possible while they still can, and adopting new energy solutions as they prepare, from sources as diverse as the floorboards of destroyed schools and the pine forests in Izium, which are pockmarked with abandoned Russian trenches adjacent to a mass burial site.

“Of course, we have this race against time,” says Serhii Mahdysyuk, the Kharkiv regional director in charge of housing, services, fuel, and energy. “Unfortunately, we probably stand in front of the biggest challenge in Ukraine.”

That is not only because of the scale of liberated territory, he says, but also because the Kharkiv region shares a long border with Russia, as well as with the Russian-controlled areas of the eastern Donbas.

“It’s a great mixture of all threats, and we are sure that shelling and bombings will continue, but we are ready for this,” says Mr. Mahdysyuk. “We know our weak spots that Russia can destroy, but we are prepared for what to do in these situations.”

Ukraine’s battlefield gains have meant a surging need to pick up the pieces after Russian occupation, even as electricity reserves are holding if no new strikes occur, to ensure habitable conditions as more and more surviving residents require services, and as others return to scenes of devastation.

Restoring electricity is the top priority, amid shifting international assistance such as the end of U.S. grid support, because that often restarts running water, too, says Mr. Mahdysyuk. But before that, the area beneath broken power lines must be de-mined.

Indeed, members of an electricity team reconnecting cables on the outskirts of Balakliia – one of the first towns to see power restored, at the end of September – say they lost two fellow workers in the previous two weeks. One died after stepping on an anti-personnel mine, another when his vehicle hit an anti-tank device.

Ukrainian electricity workers restore power lines damaged during six months of Russian military occupation in Balakliia, Ukraine, Sept. 29, 2022. Ukrainians in liberated territory say the restoration of the electrical grid, and with it often the water supply, is a return to civilization.
“For now, our biggest problem is mines,” says the team leader, who gave the name Andrii. “It’s fine within the cities, but in the fields it’s a disaster because it’s very difficult to see them. There is a lot of [them] around here – it will take years and years to get rid of.”

Yet officials only have a few weeks to execute plans to provide for hundreds of thousands of residents in this region, in their various states of need and distress. Some 50 field kitchens capable of feeding 200 to 300 people each have been ordered. Another 1,000 mobile stoves are on their way.

And authorities will provide nearly 200,000 cubic yards of firewood for those who have no access to it, and may have no other means of keeping warm – or where shelling continues to disrupt repairs, says Mr. Mahdysyuk.

“The level of opportunity and resources we have is not the same as the level of destruction,” he says. People in districts and buildings too destroyed to have services restored soon, such as in Saltivka in Kharkiv city, may be moved.

U.A.E. Becomes First Arab Nation to Open a Nuclear Power Plant

UAE Nuclear Power Plant launches the Barakah facility, delivering clean electricity to the Middle East under IAEA safeguards amid Gulf tensions, proliferation risks, and debates over renewables, natural gas, grid resilience, and energy security.

 

Key Points

The UAE Nuclear Power Plant, Barakah, is a civilian facility expected to supply 25% of electricity under IAEA oversight.

✅ Barakah reactors target 25% of national electricity.

✅ Operates under IAEA oversight, no enrichment per US 123 deal.

✅ Raises regional security, proliferation, and environmental concerns.

 

The United Arab Emirates became the first Arab country to open a nuclear power plant on Saturday, following a crucial step in Abu Dhabi earlier in the project, raising concerns about the long-term consequences of introducing more nuclear programs to the Middle East.

Two other countries in the region — Israel and Iran — already have nuclear capabilities. Israel has an unacknowledged nuclear weapons arsenal and Iran has a controversial uranium enrichment program that it insists is solely for peaceful purposes.

The U.A.E., a tiny nation that has become a regional heavyweight and international business center, said it built the plant to decrease its reliance on the oil that has powered and enriched the country and its Gulf neighbors for decades. It said that once its four units were all running, the South Korean-designed plant would provide a quarter of the country’s electricity, with Unit 1 reaching 100% power as a milestone toward commercial operations.

Seeking to quiet fears that it was trying to build muscle to use against its regional rivals, it has insisted that it intends to use its nuclear program only for energy purposes.

But with Iran in a standoff with Western powers over its nuclear program, Israel in the neighborhood and tensions high among Gulf countries, some analysts view the new plant — and any that may follow — as a security and environmental headache. Other Arab countries, including Saudi Arabia and Iraq, are also starting or planning nuclear energy programs.

The Middle East is already riven with enmities that pit Saudi Arabia and the U.A.E. against Iran, Qatar and Iran’s regional proxies. One of those proxies, the Yemen-based Houthi rebel group, claimed an attack on the Barakah plant when it was under construction in 2017.

And Iran is widely believed to be behind a series of attacks on Saudi oil facilities and oil tankers passing through the Gulf over the last year.

“The UAE’s investment in these four nuclear reactors risks further destabilizing the volatile Gulf region, damaging the environment and raising the possibility of nuclear proliferation,” Paul Dorfman, a researcher at University College London’s Energy Institute, wrote in an op-ed in March.

Noting that the U.A.E. had other energy options, including “some of the best solar energy resources in the world,” he added that “the nature of Emirate interest in nuclear may lie hidden in plain sight — nuclear weapon proliferation.”
But the U.A.E. has said it considered natural gas and renewable energy sources before dismissing them in favor of nuclear energy because they would not produce enough for its needs.

Offering evidence that its intentions are peaceful, it points to its collaborations with the International Atomic Energy Agency, which has reviewed the Barakah project, and the United States, with which it signed a nuclear energy cooperation agreement in 2009 that allows it to receive nuclear materials and technical assistance from the United States while barring it from uranium enrichment and other possible bomb-development activities.

That has not persuaded Qatar, which last year lodged a complaint with the international nuclear watchdog group over the Barakah plant, calling it “a serious threat to the stability of the region and its environment.”

The U.A.E.’s oil exports account for about a quarter of its total gross domestic product. Despite its gusher of oil, it has imported increasing amounts of natural gas in recent years in part to power its energy-intensive desalination plants.

“We proudly witness the start of Barakah nuclear power plant operations, in alignment with the highest international safety standards,” Mohammed bin Zayed, the U.A.E.’s de facto ruler, tweeted on Saturday.

The new nuclear facility, which is in the Gharbiya region on the coast, close to Qatar and Saudi Arabia, is the first of several prospective Middle East nuclear plants, even as Europe reduces nuclear capacity elsewhere. Egypt plans to build a power plant with four nuclear reactors.

Saudi Arabia is also building a civilian nuclear reactor while pursuing a nuclear cooperation deal with the United States, and globally, China's nuclear program remains on a steady development track, though the Trump administration has said it would sign such an agreement only if it includes safeguards against weapons development.

Ontario Launches Largest Competitive Energy Procurement in Province’s History

Ontario Competitive Energy Procurement accelerates renewables, boosts grid reliability, and invites competitive bids across solar, wind, natural gas, and storage, driving innovation, lower costs, and decarbonization to meet rising electricity demand and ensure power supply.

 

Key Points

Ontario Competitive Energy Procurement is a competitive bidding program to deliver reliable, low-carbon electricity.

✅ Competitive bids from renewables, gas, and storage

✅ Targets grid reliability, affordability, and emissions

✅ Phased evaluations: technical, financial, environmental

 

Ontario has recently marked a significant milestone in its energy sector with the launch of what is being touted as the largest competitive energy procurement process in the province’s history. This ambitious initiative is set to transform the province’s energy landscape through a broader market overhaul that fosters innovation, enhances reliability, and addresses the growing demands of Ontario’s diverse population.

A New Era of Energy Procurement

The Ontario government’s move to initiate this massive competitive procurement process underscores a strategic shift towards modernizing and diversifying the province’s energy portfolio. This procurement exercise will invite bids from a broad spectrum of energy suppliers and technologies, ranging from traditional sources like natural gas to renewable energy options such as solar and wind power. The aim is to secure a reliable and cost-effective energy supply that aligns with Ontario’s long-term environmental and economic goals.

This historic procurement process represents a major leap from previous approaches by emphasizing a competitive marketplace where various energy providers can compete on an equal footing through electricity auctions and transparent bidding. By doing so, the government hopes to drive down costs, encourage technological advancements, and ensure that Ontarians benefit from a more dynamic and resilient energy system.

Key Objectives and Benefits

The primary objectives of this procurement initiative are multifaceted. First and foremost, it seeks to enhance the reliability of Ontario’s electricity grid. As the province experiences population growth and increased energy demands, maintaining a stable and dependable supply of electricity is crucial, and interprovincial imports through an electricity deal with Quebec can complement local generation. This procurement process will help identify and integrate new sources of power that can meet these demands effectively.

Another significant goal is to promote environmental sustainability. Ontario has committed to reducing its greenhouse gas emissions through Clean Electricity Regulations and transitioning to a cleaner energy mix. By inviting bids from renewable energy sources and innovative technologies, the government aims to support its climate action plan and contribute to the province’s carbon reduction targets.

Cost-effectiveness is also a central focus of the procurement process. By creating a competitive environment, the government anticipates that energy providers will strive to offer more attractive pricing structures and fair electricity cost allocation practices for ratepayers. This, in turn, could lead to lower energy costs for consumers and businesses, fostering economic growth and improving affordability.

The Competitive Landscape

The competitive energy procurement process will be structured to encourage participation from a wide range of energy providers. This includes not only established companies but also emerging players and startups with innovative technologies. By fostering a diverse pool of bidders, the government aims to ensure that all viable options are considered, ultimately leading to a more robust and adaptable energy system.

Additionally, the process will likely involve various stages of evaluation, including technical assessments, financial analyses, and environmental impact reviews. This thorough evaluation will help ensure that selected projects meet the highest standards of performance and sustainability.

Implications for Stakeholders

The implications of this procurement process extend beyond just energy providers and consumers. Local communities, businesses, and environmental organizations will all play a role in shaping the outcomes. For communities, this initiative could mean new job opportunities and economic development, particularly in regions where new energy projects are developed. For businesses, the potential for lower energy costs and access to innovative energy solutions, including demand-response initiatives like the Peak Perks program, could drive growth and competitiveness.

Environmental organizations will be keenly watching the process to ensure that it aligns with broader sustainability goals. The inclusion of renewable energy sources and advanced technologies will be a critical factor in evaluating the success of the initiative in meeting Ontario’s climate objectives.

Looking Ahead

As Ontario embarks on this unprecedented energy procurement journey, the outcomes will be closely watched by various stakeholders. The success of this initiative will depend on the quality and diversity of the bids received, the efficiency of the evaluation process, and the ability to integrate new energy sources into the existing grid, while advancing energy independence where feasible.

In conclusion, Ontario’s launch of the largest competitive energy procurement process in its history is a landmark event that holds promise for a more reliable, sustainable, and cost-effective energy future. By embracing competition and innovation, the province is setting a new standard for energy procurement that could serve as a model for other regions seeking to modernize their energy systems. The coming months will be crucial in determining how this bold initiative will shape Ontario’s energy landscape for years to come.

A Texas-Sized Gas-for-Electricity Swap

Texas Heat Pump Electrification replaces natural gas furnaces with electric heating across ERCOT, cutting carbon emissions, lowering utility bills, shifting summer peaks to winter, and aligning higher loads with strong seasonal wind power generation.

 

Key Points

Statewide shift from gas furnaces to heat pumps in Texas, reducing emissions and bills while moving grid peak to winter.

✅ Up to $452 annual utility savings per household

✅ CO2 cuts up to 13.8 million metric tons in scenarios

✅ Winter peak rises, summer peak falls; wind aligns with load

 

What would happen if you converted all the single-family homes in Texas from natural gas to electric heating?

According to a paper from Pecan Street, an Austin-based energy research organization, the transition would reduce climate-warming pollution, save Texas households up to $452 annually on their utility bills, and flip the state from a summer-peaking to a winter-peaking system. And that winter peak would be “nothing the grid couldn’t evolve to handle,” according to co-author Joshua Rhodes, a view echoed by analyses outlining Texas grid reliability improvements statewide today.

The report stems from the reality that buildings must be part of any comprehensive climate action plan.

“If we do want to decarbonize, eventually we do have to move into that space. It may not be the lowest-hanging fruit, but eventually we will have to get there,” said Rhodes.

Rhodes is a founding partner of the consultancy IdeaSmiths and an analyst at Vibrant Clean Energy. Pecan Street commissioned the study, which is distilled from a larger original analysis by IdeaSmiths, at the request of the nonprofit Environmental Defense Fund.

In an interview, Rhodes said, “The goal and motivation were to put bounding on some of the claims that have been made about electrification: that if we electrify a lot of different end uses or sectors of the economy...power demand of the grid would double.”

Rhodes and co-author Philip R. White used an analysis tool from the National Renewable Energy Laboratory called ResStock to determine the impact of replacing natural-gas furnaces with electric heat pumps in homes across the ERCOT service territory, which encompasses 90 percent of Texas’ electricity load.

Rhodes and White ran 80,000 simulations in order to determine how heat pumps would perform in Texas homes and how the pumps would impact the ERCOT grid.

The researchers modeled the use of “standard efficiency” (ducted, SEER 14, 8.2 HSPF air-source heat pump) and “superior efficiency” (ductless, SEER 29.3, 14 HSPF mini-split heat pump) heat pump models against two weather data sets — a typical meteorological year, and 2011, which had extreme weather in both the winter and summer and highlighted blackout risks during severe heat for many regions.

Emissions were calculated using Texas’ power sector data from 2017. For energy cost calculations, IdeaSmiths used 10.93 cents per kilowatt-hour for electricity and 8.4 cents per therm for natural gas.

Nothing the grid can't handle
Rhodes and White modeled six scenarios. All the scenarios resulted in annual household utility bill savings — including the two in which annual electricity demand increased — ranging from $57.82 for the standard efficiency heat pump and typical meteorological year to $451.90 for the high-efficiency heat pump and 2011 extreme weather year.

“For the average home, it was cheaper to switch. It made economic sense today to switch to a relatively high-efficiency heat pump,” said Rhodes. “Electricity bills would go up, but gas bills can go down.”

All the scenarios found carbon savings too, with CO2 reductions ranging from 2.6 million metric tons with a standard efficiency heat pump and typical meteorological year to 13.8 million metric tons with the high-efficiency heat pump in 2011-year weather.

Peak electricity demand in Texas would shift from summer to winter. Because heat pumps provide both high-efficiency space heating and cooling, in the scenario with “superior efficiency” heat pumps, the summer peak drops by nearly 24 percent to 54 gigawatts compared to ERCOT’s 71-gigawatt 2016 summer peak, even as recurring strains on the Texas power grid during extreme conditions persist.

The winter peak would increase compared to ERCOT’s 66-gigawatt 2018 winter peak, up by 22.73 percent to 81 gigawatts with standard efficiency heat pumps and up by 10.6 percent to 73 gigawatts with high-efficiency heat pumps.

“The grid could evolve to handle this. This is not a wholesale rethinking of how the grid would have to operate,” said Rhodes.

He added, “There would be some operational changes if we went to a winter-peaking grid. There would be implications for when power plants and transmission lines schedule their downtime for maintenance. But this is not beyond the realm of reality.”

And because Texas’ wind power generation is higher in winter, a winter peak would better match the expected higher load from all-electric heating to the availability of zero-carbon electricity.

 

A conservative estimate
The study presented what are likely conservative estimates of the potential for heat pumps to reduce carbon pollution and lower peak electricity demand, especially when paired with efficiency and demand response strategies that can flatten demand.

Electric heat pumps will become cleaner as more zero-carbon wind and solar power are added to the ERCOT grid, as utilities such as Tucson Electric Power phase out coal. By the end of 2018, 30 percent of the energy used on the ERCOT grid was from carbon-free sources.

According to the U.S. Energy Information Administration, three in five Texas households already use electricity as their primary source of heat, much of it electric-resistance heating. Rhodes and White did not model the energy use and peak demand impacts of replacing that electric-resistance heating with much more energy efficient heat pumps.

“Most of the electric-resistance heating in Texas is located in the very far south, where they don’t have much heating at all,” Rhodes said. “You would see savings in terms of the bills there because these heat pumps definitely operate more efficiently than electric-resistance heating for most of the time.”

Rhodes and White also highlighted areas for future research. For one, their study did not factor in the upfront cost to homeowners of installing heat pumps.

“More study is needed,” they write in the Pecan Street paper, “to determine the feasibility of various ‘replacement’ scenarios and how and to what degree the upgrade costs would be shared by others.”

Research from the Rocky Mountain Institute has found that electrification of both space and water heating is cheaper for homeowners over the life of the appliances in most new construction, when transitioning from propane or heating oil, when a gas furnace and air conditioner are replaced at the same time, and when rooftop solar is coupled with electrification, aligning with broader utility trends toward electrification.

More work is also needed to assess the best way to jump-start the market for high-efficiency all-electric heating. Rhodes believes getting installers on board is key.

“Whenever a homeowner’s making a decision, if their system goes out, they lean heavily on what the HVAC company suggests or tells them because the average homeowner doesn’t know much about their systems,” he said.

More work is also needed to assess the best way to jump-start the market for high-efficiency all-electric heating, and how utility strategies such as smart home network programs affect adoption too. Rhodes believes getting installers on board is key.
