Vancouver Natural Gas Ban Reversal spotlights energy policy, electrification tradeoffs, heat pumps, emissions, grid reliability, and affordability, reshaping building codes and decarbonization pathways while inviting stakeholders to weigh practical constraints and climate goals.

Key Points

Vancouver ending its ban on natural gas in new homes to balance climate goals with reliability, costs, and technology.

✅ Balances emissions goals with reliability and affordability

✅ Impacts builders, homeowners, and energy infrastructure

✅ Spurs debate on electrification, heat pumps, and grid capacity

In a significant policy shift, Vancouver has decided to lift its ban on natural gas appliances in new homes, a move that marks a pivotal moment in the city's energy policy and environmental strategy. This decision, announced recently and following the city's Clean Energy Champion recognition for Bloedel upgrades, has sparked a broader conversation about the future of energy systems and the balance between environmental goals and practical energy needs. Stewart Muir, CEO of Resource Works, argues that this reversal should catalyze a necessary dialogue on energy choices, highlighting both the benefits and challenges of such a policy change.

Vancouver's original ban on natural gas appliances was part of a broader initiative aimed at reducing greenhouse gas emissions and promoting sustainability, including progress toward phasing out fossil fuels where feasible over time. The city had adopted stringent regulations to encourage the use of electric heat pumps and other low-carbon technologies in new residential buildings. This move was aligned with Vancouver’s ambitious climate goals, which include achieving carbon neutrality by 2050 and significantly cutting down on fossil fuel use.

However, the recent decision to reverse the ban reflects a growing recognition of the complexities involved in transitioning to entirely new energy systems. The city's administration acknowledged that while electric alternatives offer environmental benefits, they also come with challenges that can affect homeowners, builders, and the broader energy infrastructure, including options for bridging the electricity gap with Alberta to enhance regional reliability.

Stewart Muir argues that Vancouver’s policy shift is not just about natural gas appliances but represents a larger conversation about energy system choices and their implications. He suggests that the reversal of the ban provides an opportunity to address key issues related to energy reliability, affordability, and the practicalities of integrating new technologies, including electrified LNG options for industry within the province into existing systems.

One of the primary reasons behind the reversal is the recognition of the practical limitations and costs associated with transitioning to electric-only systems. For many homeowners and builders, natural gas appliances have long been a reliable and cost-effective option. The initial ban on these appliances led to concerns about increased construction costs and potential disruptions for homeowners who were accustomed to natural gas heating and cooking.

In addition to cost considerations, there are concerns about the reliability and efficiency of electric alternatives. Natural gas has been praised for its stable energy supply and efficient performance, especially in colder climates where electric heating systems might struggle to maintain consistent temperatures or fully utilize Site C's electricity under peak demand. By reversing the ban, Vancouver acknowledges that a one-size-fits-all approach may not be suitable for every situation, particularly when considering diverse housing needs and energy demands.

Muir emphasizes that the reversal of the ban should prompt a broader discussion about how to balance environmental goals with practical energy needs. He argues that rather than enforcing a blanket ban on specific technologies, it is crucial to explore a range of solutions that can effectively address climate objectives while accommodating the diverse requirements of different communities and households.

The debate also touches on the role of technological innovation in achieving sustainability goals. As energy technologies continue to evolve, renewable electricity is coming on strong and new solutions and advancements could potentially offer more efficient and environmentally friendly alternatives. The conversation should include exploring these innovations and considering how they can be integrated into existing energy systems to support long-term sustainability.

Moreover, Muir advocates for a more inclusive approach to energy policy that involves engaging various stakeholders, including residents, businesses, and energy experts. A collaborative approach can help identify practical solutions that address both environmental concerns and the realities of everyday energy use.

In the broader context, Vancouver’s decision reflects a growing trend in cities and regions grappling with energy transitions. Many urban centers are evaluating their energy policies and considering adjustments based on new information and emerging technologies. The key is to find a balance that supports climate goals such as 2050 greenhouse gas targets while ensuring that energy systems remain reliable, affordable, and adaptable to changing needs.

As Vancouver moves forward with its revised policy, it will be important to monitor the outcomes and assess the impacts on both the environment and the community. The reversal of the natural gas ban could serve as a case study for other cities facing similar challenges and could provide valuable insights into how to navigate the complexities of energy transitions.

In conclusion, Vancouver’s decision to reverse its ban on natural gas appliances in new homes is a significant development that opens the door for a critical dialogue about energy system choices. Stewart Muir’s call for a broader conversation emphasizes the need to balance environmental ambitions with practical considerations, such as cost, reliability, and technological advancements. As cities continue to navigate their energy futures, finding a pragmatic and inclusive approach will be essential in achieving both sustainability and functionality in energy systems.

EV Decarbonization Strategy weighs life-cycle emissions and climate targets, highlighting mode shift to public transit, cycling, and walking, grid decarbonization, renewable energy, and charging infrastructure to cut greenhouse gases while reducing private car dependence.

Key Points

A plan to cut transport emissions by pairing EV adoption with mode shift, clean power, and less private car use.

✅ Prioritize mode shift: transit, cycling, and walking.

✅ Electrify remaining vehicles with clean, renewable power.

✅ Expand charging, improve batteries, and manage critical minerals.

California recently announced that it plans to ban the sales of gas-powered vehicles by 2035, a move similar to a 2035 electric vehicle mandate seen elsewhere, Ontario has invested $500 million in the production of electric vehicles (EVs) and Tesla is quickly becoming the world's highest-valued car company.

It almost seems like owning an electric vehicle is a silver bullet in the fight against climate change, but it isn't, as a U of T study explains today. What we should also be focused on is whether anyone should use a private vehicle at all.
 
As a researcher in sustainable mobility, I know this answer is unsatisfying. But this is where my latest research has led.

Battery EVs, such as the Tesla Model 3 - the best selling EV in Canada in 2020 - have no tailpipe emissions. But they do have higher production and manufacturing emissions than conventional vehicles, and often run on electricity that comes from fossil fuels.

Almost 18 per cent of the electricity generated in Canada came from fossil fuels in 2019, and even as Canada's EV goals grow more ambitious today, the grid mix varies from zero in Quebec to 90 per cent in Alberta.
 
Researchers like me compare the greenhouse gas emissions of an alternative vehicle, such as an EV, with those of a conventional vehicle over a vehicle lifetime, an exercise known as a life-cycle assessment. For example, a Tesla Model 3 compared with a Toyota Corolla can provide up to 75 per cent reduction in greenhouse gases emitted per kilometre travelled in Quebec, but no reductions in Alberta.

Hundreds of millions of new cars

To avoid extreme and irreversible impacts on ecosystems, communities and the overall global economy, we must keep the increase in global average temperatures to less than 2 C - and ideally 1.5 C - above pre-industrial levels by the year 2100.

We can translate these climate change targets into actionable plans. First, we estimate greenhouse gas emissions budgets using energy and climate models for each sector of the economy and for each country. Then we simulate future emissions, taking alternative technologies into account, as well as future potential economic and societal developments.

I looked at the U.S. passenger vehicle fleet, which adds up to about 260 million vehicles, while noting the potential for Canada-U.S. collaboration in this transition, to answer a simple question: Could the greenhouse gas emissions from the sector be brought in line with climate targets by replacing gasoline-powered vehicles with EVs?

The results were shocking. Assuming no changes to travel behaviours and a decarbonization of 80 per cent of electricity, meeting a 2 C target could require up to 300 million EVs, or 90 per cent of the projected U.S. fleet, by 2050. That would require all new purchased vehicles to be electric from 2035 onwards.

To put that into perspective, there are currently 880,000 EVs in the U.S., or 0.3 per cent of the fleet. Even the most optimistic projections, despite hype about an electric-car revolution gaining steam, from the International Energy Agency suggest that the U.S. fleet will only be at about 50 per cent electrified by 2050.

Massive and rapid electrification

Still, 90 per cent is theoretically possible, isn't it? Probably, but is it desirable?

In order to hit that target, we'd need to very rapidly overcome all the challenges associated with EV adoption, such as range anxiety, the higher purchase cost and availability of charging infrastructure.
 
A rapid pace of electrification would severely challenge the electricity infrastructure and the supply chain of many critical materials for the batteries, such as lithium, manganese and cobalt. It would require vast capacity of renewable energy sources and transmission lines, widespread charging infrastructure, a co-ordination between two historically distinct sectors (electricity and transportation systems) and rapid innovations in electric battery technologies. I am not saying it's impossible, but I believe it's unlikely.

Read more: There aren't enough batteries to electrify all cars - focus on trucks and buses instead

So what? Shall we give up, accept our collective fate and stop our efforts at electrification?

On the contrary, I think we should re-examine our priorities and dare to ask an even more critical question: Do we need that many vehicles on the road?

Buses, trains and bikes

Simply put, there are three ways to reduce greenhouse gas emissions from passenger transport: avoid the need to travel, shift the transportation modes or improve the technologies. EVs only tackle one side of the problem, the technological one.

And while EVs do decrease emissions compared with conventional vehicles, we should be comparing them to buses, including leading electric bus fleets in North America, trains and bikes. When we do, their potential to reduce greenhouse gas emissions disappears because of their life cycle emissions and the limited number of people they carry at one time.

If we truly want to solve our climate problems, we need to deploy EVs along with other measures, such as public transit and active mobility. This fact is critical, especially given the recent decreases in public transit ridership in the U.S., mostly due to increasing vehicle ownership, low gasoline prices and the advent of ride-hailing (Uber, Lyft)

Governments need to massively invest in public transit, cycling and walking infrastructure to make them larger, safer and more reliable, rather than expanding EV subsidies alone. And we need to reassess our transportation needs and priorities.

The road to decarbonization is long and winding. But if we are willing to get out of our cars and take a shortcut through the forest, we might get there a lot faster.

Central Asia power shortages strain grids across Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistan, and Turkmenistan, driven by drought-hit hydropower, aging coal and gas plants, rising demand, cryptomining loads, and winter peak consumption risks.

Key Points

Regionwide blackouts from drought, aging plants and grids, rising demand, and winter peaks stressing Central Asia.

✅ Drought slashes hydropower in Kyrgyzstan, Tajikistan, Uzbekistan

✅ Aging coal and gas TPPs and weak grids cause frequent outages

✅ Cryptomining loads and winter heating spike demand and stress supply

Central Asians from western Kazakhstan to southern Tajikistan are suffering from power and energy shortages that have caused hardship and emergency situations affecting the lives of millions of people.

On October 14, several units at three power plants in northeastern Kazakhstan were shut down in an emergency that resulted in a loss of more than 1,000 megawatts (MW) of electricity.

It serves as an example of the kind of power failures that plague the region 30 years after the Central Asian countries gained independence and despite hundreds of millions of dollars being invested in energy infrastructure and power grids, and echo risks seen in other advanced markets such as Japan's near-blackouts during recent cold snaps.

Some of the reasons for these problems are clear, but with all the money these countries have allocated to their energy sectors and financial help they have received from international financial institutions, it is curious the situation is already so desperate with winter officially still weeks away.

The Current Problems
Three power plants were affected in the October 14 shutdowns of units: Ekibastuz-1, Ekibastuz-2, and the Aksu power plant.

Ekibastuz-1 is the largest power plant in Kazakhstan, capable of generating some 4,000 MW, roughly 13 percent of Kazakhstan’s total power output.

The Kazakhstan Electricity Grid Operating Company (KEGOC) explained the problems resulted partially from malfunctions and repair work, but also from overuse of the system that the government would later say was due to cryptominers, a large number of whom have moved to Kazakhstan recently from China after Beijing banned the mining needed by Bitcoin and other cryptocurrencies, amid its own China's power cuts across several provinces in 2021.

But between November 8 and 9, rolling blackouts were reported in the East Kazakhstan, North Kazakhstan, and Kyzylorda provinces, as well as the area around Almaty, Kazakhstan’s biggest city, and Shymkent, its third largest city.

People in Uzbekistan say they, too, are facing blackouts that the Energy Ministry described as “short-term outages,” even as authorities have looked to export electricity to Afghanistan to support regional demand, though it has been clear for several weeks that the country will have problems with natural gas supplies this winter.

Power lines in Uzbekistan
Kyrgyz President Sadyr Japarov continues to say there won't be any power rationing in Kyrgyzstan this winter, but at the end of September the National Energy Holding Company ordered “restrictions on the lighting of secondary streets, advertisements, and facades of shops, cafes, and other nonresidential customers.”

Many parts of Tajikistan are already experiencing intermittent supplies of electricity.

Even in Turkmenistan, a country with the fourth-largest reserves of natural gas in the world, there were reports of problems with electricity and heating in the capital, Ashgabat.

What Is Going On?
The causes of some of these problems are easy to see.

The population of the region has grown significantly, with the population of Central Asia when the Soviet Union collapsed in late 1991 being some 50 million and today about 75 million.

Kyrgyzstan and Tajikistan are mountainous countries that have long been touted for their hydropower potential and some 90 percent of Kyrgyzstan’s domestically produced electricity and 98 percent of Tajikistan’s come from hydropower.

But a severe drought that struck Central Asia this year has resulted in less hydropower and, in general, less energy for the region, similar to constraints seen in Europe's reduced hydro and nuclear output this year.

Tajik authorities have not reported how low the water in the country’s key reservoirs is, but Kyrgyzstan has reported the water level in the reservoir at its Toktogul hydropower plant (HPP) is 11.8 billion cubic meters (bcm), the lowest level in years and far less than the 14.7 bcm of water it had in November 2020.

The Toktogul HPP, with an installed capacity of 1,200 MW, provides some 40 percent of the country's domestically produced electricity, but operating the HPP this winter to generate desperately needed energy brings the risk of leaving water levels at the reservoir critically low next spring and summer when the water is also needed for agricultural purposes.

This year’s drought is something Kyrgyzstan and Tajikistan will have to take into consideration as they plan how to provide power for their growing populations in the future. Hydropower is a desirable option but may be less reliable with the onset of climate change, prompting interest in alternatives such as Ukraine's wind power to diversify generation.

Uzbekistan is also feeling the effects of this year’s drought, and, like the South Caucasus where Georgia's electricity imports have increased, supply shortfalls are testing grids.

According to the International Energy Agency, HPPs account for some 12 percent of Uzbekistan’s generating capacity.

Uzbekistan’s Energy Ministry attributed low water levels at HPPs that have caused a 23 percent decrease in hydropower generation this year.

A reservoir in Kyrgyzstan
Kazakhstan and Uzbekistan are the most populous Central Asian countries, and both depend on thermal power plants (TPP) for generating most of their electricity.

Most of the TPPs in Kazakhstan are coal-fired, while most of the TPPs in Uzbekistan are gas-fired.

Kazakhstan has 68 power plants, 80 percent of which are coal-fired TPPs, and most are in the northern part of the country where the largest deposits of coal are located. Kazakhstan has the world's 10th largest reserves of coal.

About 88 percent of Uzbekistan’s electricity comes from TTPs, most of which use natural gas.

Uzbekistan’s proven reserves are some 800 billion cubic meters, but gas production in Uzbekistan has been decreasing.

In December 2020, Uzbek President Shavkat Mirziyoev ordered a halt to the country’s gas exports and instructed that gas to be redirected for domestic use. Mirziyoev has already given similar instructions for this coming winter.

How Did It Come To This?
The biggest problem with the energy infrastructure in Central Asia is that it is generally very old. Nearly all of its power plants date back to the Soviet era -- and some well back into the Soviet period.

The use of power plants and transmission lines that some describe as “obsolete” and a few call “decrepit” has unfortunately been a necessity in Central Asia, even as regional players pursue new interconnections like Iran's plan to transmit electricity to Europe as a power hub.

Reporting on Kazakhstan in September 2016, the Asian Development Bank (ADB) said, “70 percent of the power generation infrastructure is in need of rehabilitation.”

The Ekibastuz-1 TPP is relatively new by the power-plant standards of Central Asia. The first unit of the eight units of the TPP was commissioned in 1980.

The first unit at the AKSU TPP was commissioned in 1968, and the first unit of the gas- and fuel-fired TPP in southern Kazakhstan’s Zhambyl Province was commissioned in 1967.

Miami Valley EV Chargers Expansion strengthens Level 2 charging infrastructure across Dayton, with Ohio EPA funding and Volkswagen settlement support, easing range anxiety and promoting sustainable transportation at Austin Landing and high-traffic destinations.

Key Points

An Ohio initiative installing 24 Level 2 stations to boost EV adoption, reduce range anxiety, and expand access in Dayton.

✅ 24 new Level 2 chargers at high-traffic regional sites

✅ Ohio EPA and VW settlement funds support deployment

✅ Reduces range anxiety, advancing sustainable mobility

The Miami Valley region in Ohio is accelerating its transition to electric vehicles (EVs) with the installation of 24 new Level 2 EV chargers, funded through a $1.1 million project supported by the Ohio Environmental Protection Agency (EPA). This initiative aims to enhance EV accessibility and alleviate "range anxiety" among drivers as the broader U.S. EV boom tests grid readiness.

Strategic Locations Across the Region

The newly installed chargers are strategically located in high-traffic areas to maximize their utility as national charging networks compete to expand coverage across travel corridors. Notable sites include Austin Landing, the Dayton Art Institute, the Oregon District, Caesar Creek State Park, and the Rose Music Center. These locations were selected to ensure that EV drivers have convenient access to charging stations throughout the region, similar to how Ontario streamlines station build-outs to place chargers where drivers already travel.

Funding and Implementation

The project is part of Ohio's broader effort to expand EV infrastructure, reflecting the evolution of U.S. charging infrastructure while utilizing funds from the Volkswagen Clean Air Act settlement. The Ohio EPA awarded approximately $3.25 million statewide for the installation of Level 2 EV chargers, with the Miami Valley receiving a significant portion of this funding, while Michigan utility programs advance additional investments to scale regional infrastructure.

Impact on the Community

The expansion of EV charging infrastructure is expected to have several positive outcomes. It will provide greater convenience for current EV owners and encourage more residents to consider electric vehicles as a viable transportation option, including those in apartments and condos who benefit from expanded access. Additionally, the increased availability of charging stations supports the state's environmental goals by promoting the adoption of cleaner, more sustainable transportation.

Looking Ahead

As the adoption of electric vehicles continues to grow, the Miami Valley's investment in EV infrastructure positions the region as a leader in sustainable transportation as utilities pursue ambitious charging strategies to meet demand. The success of this project may serve as a model for other regions looking to expand their EV charging networks. This initiative reflects a significant step towards a more sustainable and accessible transportation future for the Miami Valley.

Smart Grid Modernization unites distributed energy resources, energy storage, EV charging, advanced metering, and bidirectional power flows to upgrade transmission and distribution infrastructure for reliability, resilience, cybersecurity, and affordable, clean power.

Key Points

Upgrading grid hardware and software to integrate DERs, storage, and EVs for a reliable and affordable power system.

✅ Enables DER, storage, and EV integration with bidirectional flows

✅ Improves reliability, resilience, and grid cybersecurity

✅ Requires early investment in sensors, inverters, and analytics

Much has been written, predicted, and debated in recent years about the future of the electricity system. The discussion isn’t simply about fossil fuels versus renewables, as often dominates mainstream energy discourse. Rather, the discussion is focused on something much larger and more fundamental: the very design of how and where electricity should be generated, delivered, and consumed.

Central to this discussion are arguments in support of, or in opposition to, the traditional model versus that of the decentralized or “emerging” model. But this is a false choice. The only choice that needs making is how to best transition to a smarter grid, and do so in a reliable and affordable manner that reflects grid modernization affordability concerns for utilities today. And the most effective and immediate means to accomplish that is to encourage and facilitate early investment in grid-related infrastructure and technology.

The traditional, or centralized, model has evolved since the days of Thomas Edison, but the basic structure is relatively unchanged: generate electrons at a central power plant, transmit them over a unidirectional system of high-voltage transmission lines, and deliver them to consumers through local distribution networks. The decentralized, or emerging, model envisions a system that moves away from the central power station as the primary provider of electricity to a system in which distributed energy resources, energy storage, electric vehicles, peer-to-peer transactions, connected appliances and devices, and sophisticated energy usage, pricing, and load management software play a more prominent role.

Whether it’s a fully decentralized and distributed power system, or the more likely centralized-decentralized hybrid, it is apparent that the way in which electricity is produced, delivered, and consumed will differ from today’s traditional model. And yet, in many ways, the fundamental design and engineering that makes up today’s electric grid will serve as the foundation for achieving a more distributed future. Indeed, as the transition to a smarter grid ramps up, the grid’s basic structure will remain the underlying commonality, allowing the grid to serve as a facilitator to integrate emerging technologies, including EV charging stations, rooftop solar, demand-side management software, and other distributed energy resources, while maximizing their potential benefits and informing discussions about California’s grid reliability under ambitious transition goals.

A loose analogy here is the internet. In its infancy, the internet was used primarily for sending and receiving email, doing homework, and looking up directions. At the time, it was never fully understood that the internet would create a range of services and products that would impact nearly every aspect of everyday life from online shopping, booking travel, and watching television to enabling the sharing economy and the emerging “Internet of Things.”

Uber, Netflix, Amazon, and Nest would not be possible without the internet. But the rapid evolution of the internet did not occur without significant investment in internet-related infrastructure. From dial-up to broadband to Wi-Fi, companies have invested billions of dollars to update and upgrade the system, allowing the internet to maximize its offerings and give way to technological breakthroughs, innovative businesses, and ways to share and communicate like never before.  

The electric grid is similar; it is both the backbone and the facilitator upon which the future of electricity can be built. If the vision for a smarter grid is to deploy advanced energy technologies, create new business models, and transform the way electricity is produced, distributed, and consumed, then updating and modernizing existing infrastructure and building out new intelligent infrastructure need to be top priorities. But this requires money. To be sure, increased investment in grid-related infrastructure is the key component to transitioning to a smarter grid; a grid capable of supporting and integrating advanced energy technologies within a more digital grid architecture that will result in a cleaner, more modern and efficient, and reliable and secure electricity system.

The inherent challenges of deploying new technologies and resources — reliability, bidirectional flow, intermittency, visibility, and communication, to name a few, as well as emerging climate resilience concerns shaping planning today, are not insurmountable and demonstrate exactly why federal and state authorities and electricity sector stakeholders should be planning for and making appropriate investment decisions now. My organization, Alliance for Innovation and Infrastructure, will release a report Wednesday addressing these challenges facing our infrastructure, and the opportunities a distributed smart grid would provide. From upgrading traditional wires and poles and integrating smart power inverters and real-time sensors to deploying advanced communications platforms and energy analytics software, there are numerous technologies currently available and capable of being deployed that warrant investment consideration.

Making these and similar investments will help to identify and resolve reliability issues earlier, and address vulnerabilities identified in the latest power grid report card findings, which in turn will create a stronger, more flexible grid that can then support additional emerging technologies, resulting in a system better able to address integration challenges. Doing so will ease the electricity evolution in the long-term and best realize the full reliability, economic, and environmental benefits that a smarter grid can offer.

Electric Vehicle Grid Integration aligns EV charging with grid capacity using smart charging, time-of-use rates, V2G, and demand response to reduce peak load, enable renewable energy, and optimize infrastructure planning.

Key Points

Aligning EV charging with grid needs via smart charging, TOU pricing, and V2G to balance load and support renewables.

✅ Time-of-use rates shift charging to off-peak hours

✅ Smart charging responds to real-time grid signals

✅ V2G turns fleets into distributed energy storage

When Seattle City Light unveiled five new electric vehicle charging stations last month in an industrial neighborhood south of downtown, the electric utility wasn't just offering a new spot for drivers to fuel up. It also was creating a way for the service to figure out how much more power it might need as electric vehicles catch on.

Seattle aims to have nearly a third of its residents driving electric vehicles by 2030. Washington state is No. 3 in the nation in per capita adoption of plug-in cars, behind California and Hawaii. But as Washington and other states urge their residents to buy electric vehicles — a crucial component of efforts to reduce carbon emissions — they also need to make sure the electric grid can handle it amid an accelerating EV boom nationwide.

The average electric vehicle requires 30 kilowatt hours to travel 100 miles — the same amount of electricity an average American home uses each day to run appliances, computers, lights and heating and air conditioning.

An Energy Department study found that increased electrification across all sectors of the economy could boost national consumption by as much as 38 percent by 2050, in large part because of electric vehicles. The environmental benefit of electric cars depends on the electricity being generated by renewables.

So far, states predict they will be able to sufficiently boost power production. But whether electric vehicles will become an asset or a liability to the grid largely depends on when drivers charge their cars.

Electricity demand fluctuates throughout the day; demand is higher during daytime hours, peaking in the early evening. If many people buy electric vehicles and mostly try to charge right when they get home from work — as many now do — the system could get overloaded or force utilities to deliver more electricity than they are capable of producing.

In California, for example, the worry is not so much with the state’s overall power capacity, but rather with the ability to quickly ramp up production and maintain grid stability when demand is high, said Sandy Louey, media relations manager for the California Energy Commission, in an email. About 150,000 electric vehicles were sold in California in 2018 — 8 percent of all state car sales.

The state projects that electric vehicles will consume 5.4 percent of the state’s electricity, or 17,000 gigawatt hours, by 2030.

Responding to the growth in electric vehicles will present unique challenges for each state. A team of researchers from the University of Texas at Austin estimated the amount of electricity that would be required if every car on the road transitioned to electric. Wyoming, for instance, would need to nudge up its electricity production only 17 percent, while Maine would have to produce 55 percent more.

Efficiency Maine, a state trust that oversees energy efficiency and greenhouse gas reduction programs, offers rebates for the purchase of electric vehicles, part of state efforts to incentivize growth.

“We’re certainly mindful that if those projections are right, then there will need to be more supply,” said Michael Stoddard, the program’s executive director. “But it’s going to unfold over a period of the next 20 years. If we put our minds to it and plan for it, then we should be able to do it.”

A November report sponsored by the Energy Department found that there has been almost no increase in electricity demand nationwide over the past 10 years, while capacity has grown an average of 12 gigawatts per year (1 GW can power more than a half-million homes). That means energy production could climb at a similar rate and still meet even the most aggressive increase in electric vehicles, with proper planning.

Charging during off-peak hours would allow not only many electric vehicles to be added to the roads but also utilities to get more use out of power plants that run only during the limited peak times through improved grid coordination and flexible demand.

Seattle City Light and others are looking at various ways to promote charging during ideal times. One method is time-of-day rates. For the Seattle chargers unveiled last month, users will pay 31 cents per kilowatt hour during peak daytime hours and 17 cents during off-peak hours. The utility will monitor use at its charging stations to see how effective the rates are at shifting charging to more favorable times.

The utility also is working on a pilot program to study charging behavior at home. And it is partnering with customers such as King County Metro that are electrifying large vehicle fleets, including growing electric truck fleets that will demand significant power, to make sure they have both the infrastructure and charging patterns to integrate smoothly.

“Traditionally, our utility approach is to meet the load demand,” said Emeka Anyanwu, energy innovation and resources officer for Seattle City Light.

Instead, he said, the utility is working with customers to see whether they can use existing assets without the need for additional investment.

Numerous analysts say that approach is crucial.

“Even if there’s an overall increase in consumption, it really matters when that occurs,” said Sally Talberg, head of the Michigan Public Service Commission, which oversees the state’s utilities. “The encouragement of off-peak charging and other technology solutions that could come to bear could offset any negative impact.”

One of those solutions is smart charging, a system in which vehicles are plugged in but don’t charge until they receive a signal from the grid that demand has tapered off a sufficient amount. This is often paired with a lower rate for drivers who use it. Several smart-charging pilot programs are being conducted by utilities, although they have not yet been phased in widely, amid ongoing debates over charging control among manufacturers and utilities.

In many places, the increased electricity demand from electric vehicles is seen as a benefit to utilities and rate payers. In the Northwest, electricity consumption has remained relatively stagnant since 2000, despite robust population growth and development. That’s because increasing urbanization and building efficiency have driven down electricity needs.

Electric vehicles could help push electricity consumption closer to utilities’ capacity for production. That would bring in revenue for the providers, which would help defray the costs for maintaining that capacity, lowering rates for all customers.

“Having EV loads is welcome, because it’s environmentally cleaner and helps sustain revenues for utilities,” said Massoud Jourabchi, manager of economic analysis for the Northwest Power and Conservation Council, which develops power plans for the region.

Colorado also is working to promote electric cars, with the aim of putting 940,000 on the road by 2030. The state has adopted California’s zero-emission vehicles mandate, which requires automakers to reach certain market goals for their sales of cars that don’t burn fossil fuels, while extending tax credits for the purchase of such cars, investing in charging stations and electrifying state fleets.

Auto dealers have opposed the mandate, saying it infringes on consumer freedom.

“We think it should be a customer choice, a consumer choice and not a government mandate,” said Tim Jackson, president and chief executive of the Colorado Automobile Dealers Association.

Jackson also said that there’s not yet a strong consumer appetite for electric vehicles, meaning that manufacturers that fail to sell the mandated number of emission-free vehicles would be required to purchase credits, which he thinks would drive up the price of their other models.

Republicans in the state have registered similar concerns, saying electric vehicle adoption should take place based on market forces, not state intervention.

Many in the utility community are excited about the potential for electric cars to serve as mobile energy storage for the grid. Vehicle-to-grid technology, known as V2G, would allow cars charging during the day to take on surplus power from renewable energy sources.

Then, during peak demand times, electric vehicles would return some of that stored energy to the grid. As demand tapers off in the evening, the cars would be able to recharge.

In practice, V2G technology could be especially beneficial if used by heavy-duty fleets, such as school buses or utility vehicles. Those fleets would have substantial battery storage and long periods where they are idle, such as evenings and weekends — and even longer periods such as summer and the holiday season when school is out. The batteries on a bus, Jourabchi said, could store as much as 10 times the electricity needed to power a home for a day.
