Electric energy storage enables grid flexibility for renewables using utility-scale batteries and pumped-storage hydropower, delivering high round-trip efficiency, scalable capacity, and longer durations, according to EIA data as intermittent generation and demand variability increase.

 

Key Points

Electric energy storage saves power for later use using batteries and pumped storage to boost efficiency.

✅ Batteries: ~82% round-trip efficiency in 2019 (EIA)

✅ Pumped-storage: ~79% round-trip efficiency in 2019 (EIA)

✅ Pumped-storage 21.9 GW; utility-scale batteries 1.4 GW (Nov 2020)

 

Electric energy storage is becoming more important to the energy industry as the share of intermittent generating technologies, such as wind and solar, in the electricity mix increases. Electric energy storage helps to meet fluctuating demand, as many utilities see benefits from deployment, which is why it is often paired with intermittent sources. Storage technologies include batteries and pumped-storage hydropower, which capture energy and store it for later use and increasingly support EV-related grid flexibility as mobile chargers bring new options. Storage metrics can help us understand the value of the technology. Round-trip efficiency is the percentage of electricity put into storage that is later retrieved. The higher the round-trip efficiency, the less energy is lost in the storage process. According to data from the U.S. Energy Information Administration (EIA), in 2019, the U.S. utility-scale battery fleet operated with an average monthly round-trip efficiency of 82%, and pumped-storage facilities operated with an average monthly round-trip efficiency of 79%.


 

EIA’s Power Plant Operations Report provides data on utility-scale energy storage, and initiatives to enable storage in Ontario illustrate system-level integration, including the monthly electricity consumption and gross electric generation of energy storage assets, which can be used to calculate round-trip efficiency. The metrics reviewed here use the finalized data from the Power Plant Operations Report for 2019—the most recent year for which a full set of storage data is available.

Pumped-storage facilities are the largest energy storage resource in the United States, and regions anticipating tight supply, such as Ontario supply crunch, are also evaluating expanded storage portfolios. The facilities collectively account for 21.9 gigawatts (GW) of capacity and for 92% of the country’s total energy storage capacity as of November 2020.

In recent years, utility-scale battery capacity has grown rapidly as battery costs have decreased, and New York BESS is cited as a needed clean energy solution, underscoring this trend. As batteries have been increasingly paired with renewables in markets worldwide, including Ontario to rely on battery storage to meet rising demand, they have become the second-largest source of electricity storage. As of November 20, 2020, utility-scale battery capacity had 1.4 GW of operational capacity. Another 4.0 GW of battery capacity is scheduled to come online in 2021, according to EIA’s Preliminary Electric Generator Inventory.

Although battery storage has slightly higher round-trip efficiency than pumped storage, pumped-storage facilities typically operate at utilization factors that are currently twice as high as batteries. Increasing durations among battery applications could shift battery operations toward services that reward longer output periods. For example, in 2015, the weighted average battery duration was a little more than 46 minutes, but by 2019, weighted average battery durations had doubled to 1.5 hours, and emerging long-duration projects are targeting 100-hour capabilities. The role of batteries and their capability to provide high levels of round-trip efficiency may become more important as batteries continue to be deployed and as the intermittent renewables share of the electricity mix grows.

UK sets new record for wind power generation

Britain Wind Generation Record underscores onshore and offshore wind momentum, as National Grid ESO reported 20.91 GW, boosting zero-carbon electricity, renewables share, and grid stability amid milder weather, falling gas prices, and net zero goals.

 

Key Points

The Britain wind generation record is 20.91 GW, set on 30 Dec, driven by onshore and offshore turbines.

✅ Set on 30 Dec 2022 with peak output of 20.91 GW.

✅ Zero-carbon sources hit 87.2% of grid supply.

✅ Driven by onshore and offshore wind; ESO reported stability.

 

Britain has set a new record for wind generation as power from onshore and offshore turbines helped boost clean energy supplies late last year.

National Grid’s electricity system operator (ESO), which handles Great Britain’s grid operations, said that a new record for wind generation was set on 30 December, when 20.91 gigawatts (GW) were produced by turbines.

This represented the third time Britain’s fleet of wind turbines set new generation records in 2022. In May, National Grid had to ask some turbines in the west of Scotland to shut down, as the network was unable to store such a large amount of electricity when a then record 19.9GW of power was produced – enough to boil 3.5m kettles.

The ESO said a new record was also set for the share of electricity on the grid coming from zero-carbon sources – renewables and nuclear – which supplied 87.2% of total power. These sources have accounted for about 55% to 59% of power over the past couple of years.

The surge in wind generation represents a remarkable reversal in fortunes as a cold snap that enveloped Britain and Europe quickly turned to milder weather.

Power prices had soared as the freezing weather forced Britons to increase their heating use, pushing up demand for energy despite high bills.

The cold weather came with a period of low wind, reducing the production of Britain’s windfarms to close to zero.

Emergency coal-fired power units at Drax in North Yorkshire were put on standby but ultimately not used, while gas-fired generation accounted for nearly 60% of the UK’s power output at times.

However, milder weather in the UK and Europe in recent days has led to a reduction in demand from consumers and a fall in wholesale gas prices. It has also reduced the risk of power cuts this winter, which National Grid had warned could be a possibility.

Wind generation is increasingly leading the power mix in Britain and is seen as a crucial part of Britain’s move towards net zero. The prime minister, Rishi Sunak, is expected to overturn a moratorium on new onshore wind projects with a consultation on the matter due to run until March.

BC's Kootenay Region makes electric cars a priority

Accelerate Kootenays EV charging stations expand along Highway 3, adding DC fast charging and Level 2 plugs to cut range anxiety for electric vehicles in B.C., linking communities like Castlegar, Greenwood, and the Alberta border.

 

Key Points

A regional network of DC fast and Level 2 chargers along B.C.'s Highway 3 to reduce range anxiety and boost EV adoption.

✅ 13 DC fast chargers plus 40 Level 2 stations across key hubs

✅ 20-minute charging stops reduce range anxiety on Highway 3

✅ Backed by BC Hydro, FortisBC, and regional districts

 

The Kootenays are B.C.'s electric powerhouse, and as part of B.C.'s EV push the region is making significant advances to put electric cars on the road.

The region's dams generate more than half of the province's electricity needs, but some say residents in the region have not taken to electric cars, for instance.

Trish Dehnel is a spokesperson for Accelerate Kootenays, a multi-million dollar coalition involving the regional districts of East Kootenay, Central Kootenay and Kootenay Boundary, along with a number of corporate partners including Fortis B.C. and BC Hydro.

She says one of the major problems in the region — in addition to the mountainous terrain and winter driving conditions — is "range anxiety."

That's when you're not sure your electric vehicle will be able to make it to your destination without running out of power, she explained.

Now, Accelerate Kootenays is hoping a set of new electric charging stations, part of the B.C. Electric Highway project expanding along Highway 3, will make a difference.

 

No more 'range anxiety'

The expansion includes 40 Level 2 stations and 13 DC Quick Charging stations, mirroring BC Hydro's expansion across southern B.C. strategically located within the region to give people more opportunities to charge up along their travel routes, Dehnel said.

"We will have DC fast-charging stations in all of the major communities along Highway 3 from Greenwood to the Alberta border. You will be able to stop at a fast-charging station and, thanks to faster EV charging technology, charge your vehicle within 20 minutes," she said.

Castlegar car salesman Terry Klapper — who sells the 2017 Chevy Bolt electric vehicle — says it's a great step for the region as sites like Nelson's new fast-charging station come online.

"I guarantee that you'll be seeing electric cars around the Kootenays," he said.

"The interest the public has shown … [I mean] as soon as people found out we had these Bolts on the lot, we've had people coming in every single day to take a look at them and say when can I finally purchase it."

The charging stations are set to open by the end of next year.

Is it finally time to buy an electric car?

Electric Vehicles deliver longer range, faster charging, and broader price options, with incentives and lease deals reducing costs; evaluate performance, home charging, road trip needs, and vehicle types like SUVs, pickups, and vans.

 

Key Points

Electric vehicles are battery-powered cars that cut costs, boost performance, and charge at home or at fast stations.

✅ Longer range and faster charging reduce range anxiety

✅ Lower operating costs vs gas: fuel, maintenance, incentives

✅ Home Level 2 charging recommended; plan for road trips

 

Electric cars now drive farther, charge faster and come in nearly every price range. But when GMC began promoting its Hummer EV pickup truck to be released this year, it became even clearer that electric cars are primed to go mainstream for many buyers.

Once the domain of environmentalists, then early adopters, electric vehicles may soon have even truck bros kicking the gasoline habit, though sales are still behind gas cars in many markets.

With many models now available or coming soon — and arriving ahead of schedule for several automakers — including a knockoff of the lovable Volkswagen Microbus — you may be wondering if it’s finally time to buy or lease one.

Here are the essential questions to answer before you do.

(Full disclosure: I’m a convert myself after six years and 70,000 gas-free miles.)


1. Can you afford an electric car?
Electric vehicles tend to be pricy to buy but can be more affordable to lease. Finding federal, state and local government incentives can also reduce sticker shock. And, even if the monthly payment is higher than a comparable gas car, operating costs are lower.

Gas vehicles cost an average of $3,356 per year to fuel, tax and insure, while electric cost just $2,722, according to a study by Self Financial, and Consumer Reports finds EVs save money in the long run too. Find out how much you can save with the Department of Energy calculator.

 

2. How far do you need to drive on a single charge?
Although almost 60 percent of all car trips in America were less than 6 miles in 2017, according to the Department of Energy, the phrase “range anxiety” scared many would-be early adopters.

Teslas became popular in part because they offered 250 miles of range. But the range of many electric vehicles between charges is now over 200 miles; even the modestly priced Chevrolet Bolt can travel 259 miles on a single charge.

Still, electric vehicles have a “road trip problem,” according to Josh Sadlier, director of content strategy for car site Edmunds.com. “If you like road trips, you almost have to have two cars — one for around town and one for longer trips,” he says.

 

3. Where will you charge it?
If you live in an apartment without a charging station, this could be a deal breaker.

The number of public chargers increased by 60 percent worldwide in 2019, according to the International Energy Agency. While these stations — some of which are free — are more available, most electric vehicle owners install a home station for faster charging.

Electric vehicles can be charged by plugging into a common 120-volt household outlet, but it’s slow, and understanding charging costs can help you plan home use. To speed up charging, many electric vehicle owners wind up buying a 240-volt charging station and having an electrician install it for a total cost of $1,200, according to the home remodeling website Fixr.

4. What will you use the car for?
While there are a few luxury electric SUVs on the market, most electric vehicles are smaller sedans or hatchbacks with limited cargo capacity. However, the coming wave of electric cars are more versatile, and many experts expect that within a decade these options will be commonplace, including vans, such as the Microbus, and trucks, such as an electric version of the popular Ford F-150 pickup.

5. Do you enjoy performance?
This is where electric vehicles really shine. According to automotive experts, electric cars beat their gas counterparts in these ways:

Immediate response with great low-end acceleration, particularly in the 0-30 mph range.
Sure-footed handling due to the heavy battery mounted under the car, giving it a low center of gravity.
No “shift shock” from changing gears in a conventional gas car’s transmission.
Little noise except from the wind and tires.

 

Other factors
Once you consider the big questions, here are other reasons to make an electric car your next choice:

Reduced environmental guilt. There is a persistent myth that electric vehicles simply move the emissions from the tailpipe to the power generating station. Yes, producing electricity produces emissions, but many electric vehicle owners charge at night when much of the electricity would otherwise be unused. According to research published by the BBC and evidence that they are better for the planet in many scenarios electric cars reduce emissions by an average of 70 percent, depending on where people live.

Less time refueling. It takes only seconds to plug in at home, and the electric vehicle will recharge while you’re doing other things. No more searching for gas stations and standing by as your tank gulps down gasoline.

No oil changes. Dealers like a constant stream of drivers coming in for oil changes so they can upsell other services. Electric vehicles have fewer moving parts and require fewer trips to the dealership for maintenance.

Carpool lanes and other perks. Check your state regulations to see if an electric vehicle gets you access to the carpool lane, free parking or other special advantages.

Enjoy the technology. Yes, electric vehicles are more expensive, but they also tend to offer top-of-the-line comfort, safety features and technology compared with their gas counterparts.

Ford Motor Co. details plans to spend $1.8B to produce EVs

Ford Oakville Electric Vehicle Complex will anchor EV production in Ontario, adding a battery plant, retooling lines, and assembly capacity for passenger models targeting the North American market and Canada's zero-emission mandates.

 

Key Points

A retooled Ontario hub for passenger EV production, featuring on-site battery assembly and modernized lines.

✅ Retooling begins Q2 2024; EV production slated for 2025.

✅ New 407,000 sq ft battery plant for pack assembly.

✅ First full-line passenger EV production in Canada.

 

Ford Motor Co. has revealed some details of its plan to spend $1.8 billion on its Oakville Assembly Complex to turn it into an electric vehicle production hub, a government-backed Oakville EV deal, in the latest commitment by an automaker transitioning towards an electric future.

The automaker said Tuesday that it will start retooling the Ontario complex in the second quarter of 2024, bolstering Ontario's EV jobs boom, and begin producing electric vehicles in 2025.

The transformation of the Oakville site, to be renamed the Oakville Electric Vehicle Complex, will include a new 407,000 square-foot battery plant, similar to Honda's Ontario battery investment efforts, where parts produced at Ford's U.S. operations will be assembled into battery packs.

General Motors is already producing electric delivery vans in Canada, and its Ontario EV plant plans continue to expand, but Ford says this is the first time a full-line automaker has announced plans to produce passenger EVs in Canada for the North American market.

GM said in February it plans to build motors for electric vehicles at its St. Catharines, Ont. propulsion plant, aligning with the Niagara Region battery investment now underway. The motors will go into its BrightDrop electric delivery vans, which it produces in part at its Ingersoll, Ont. plant, as well as its electric pickup trucks, producing enough at the plant for 400,000 vehicles a year.

Ford's announcement is the latest commitment by an automaker transitioning towards an electric future, part of Canada's EV assembly push that is accelerating.

"Canada and the Oakville complex will play a vital role in our Ford Plus transformation," said chief executive Jim Farley in a statement.

The company has committed to invest over US$50 billion in electric vehicles globally and has a target of producing two million EVs a year by the end of 2026 as part of its Ford Plus growth plan, reflecting an EV market inflection point worldwide.

Ford didn't specify in the release which models it planned to build at the Oakville complex, which currently produces the Ford Edge and Lincoln Nautilus.

The company's spending plans were first announced in 2020 as part of union negotiations, with workers seeking long-term production commitments and the Detroit Three automakers eventually agreeing to invest in Canadian operations in concert with spending agreements with the Ontario and federal governments.

The two governments agreed to provide $295 million each in funding to secure the Ford investment.

"The partnership between Ford and Canada helps to position us as a global leader in the EV supply chain for decades to come," said Industry Minister Francois-Philippe Champagne in Ford's news release.

Funding help comes as the federal government moves to require that at least 20 percent of new vehicles sold in Canada will be zero-emission by 2026, at least 60 per cent by 2030, and 100 per cent by 2035.

Electric cars won't solve our pollution problems – Britain needs a total transport rethink

UK Transport Policy Overhaul signals bans on petrol and diesel cars, rail franchising reform, 15-minute cities, and active travel, tackling congestion, emissions, microplastics, urban sprawl, and public health with systemic, multimodal planning.

 

Key Points

A shift toward EVs, rail reform, and 15-minute cities to reduce emissions, congestion, and health risks.

✅ Phase-out of petrol and diesel car sales by 2030

✅ National rail franchising replaced with integrated operations

✅ Urban design: 15-minute cities, cycling, and active travel

 

Could it be true? That this government will bring all sales of petrol and diesel cars to an end by 2030, even as a 2035 EV mandate in Canada is derided by critics? That it will cancel all rail franchises and replace them with a system that might actually work? Could the UK, for the first time since the internal combustion engine was invented, really be contemplating a rational transport policy? Hold your horses.

Before deconstructing it, let’s mark this moment. Both announcements might be a decade or two overdue, but we should bank them as they’re essential steps towards a habitable nation.

We don’t yet know exactly what they mean, as the government has delayed its full transport announcement until later this autumn. But so far, nothing that surrounds these positive proposals makes any sense, and the so-called EV revolution often proves illusory in practice.

If the government has a vision for transport, it appears to be plug and play. We’ll keep our existing transport system, but change the kinds of vehicles and train companies that use it. But when you have a system in which structural failure is embedded, nothing short of structural change will significantly improve it.

A switch to electric cars will reduce pollution, though the benefits depend on the power mix; in Canada, Canada’s grid was 18% fossil-fuelled in 2019, for example. It won’t eliminate it, as a high proportion of the microscopic particles thrown into the air by cars, which are highly damaging to our health, arise from tyres grating on the surface of the road. Tyre wear is also by far the biggest source of microplastics pouring into our rivers and the sea. And when tyres, regardless of the engine that moves them, come to the end of their lives, we still have no means of properly recycling them.

Cars are an environmental hazard long before they leave the showroom. One estimate suggests that the carbon emissions produced in building each one equate to driving it for 150,000km. The rise in electric vehicle sales has created a rush for minerals such as lithium and copper, with devastating impacts on beautiful places. If the aim is greatly to reduce the number of vehicles on the road, and replace those that remain with battery-operated models, alongside EV battery recycling efforts, then they will be part of the solution. But if, as a forecast by the National Grid proposes, the current fleet is replaced by 35m electric cars, a University of Toronto study warns they are not a silver bullet, and we’ll simply create another environmental disaster.

Switching power sources does nothing to address the vast amount of space the car demands, which could otherwise be used for greens, parks, playgrounds and homes. It doesn’t stop cars from carving up community and turning streets into thoroughfares and outdoor life into a mortal hazard. Electric vehicles don’t solve congestion, or the extreme lack of physical activity that contributes to our poor health.

So far, the government seems to have no interest in systemic change. It still plans to spend £27bn on building even more roads, presumably to accommodate all those new electric cars. An analysis by Transport for Quality of Life suggests that this road-building will cancel out 80% of the carbon savings from a switch to electric over the next 12 years. But everywhere, even in the government’s feted garden villages and garden towns, new developments are being built around the car.

Rail policy is just as irrational, even though lessons from large electric bus fleets offer cleaner mass transit options. The construction of HS2, now projected to cost £106bn, has accelerated in the past few months, destroying precious wild places along the way, though its weak business case has almost certainly been destroyed by coronavirus.

If one thing changes permanently as a result of the pandemic, it is likely to be travel. Many people will never return to the office. The great potential of remote technologies, so long untapped, is at last being realised. Having experienced quieter cities with cleaner air, few people wish to return to the filthy past.

Like several of the world’s major cities, our capital is being remodelled in response, though why electric buses haven’t taken over remains a live question. The London mayor – recognising that, while fewer passengers can use public transport, a switch to cars would cause gridlock and lethal pollution – has set aside road space for cycling and walking. Greater Manchester hopes to build 1,800 miles of protected pedestrian and bicycle routes.

Cycling to work is described by some doctors as “the miracle pill”, massively reducing the chances of early death: if you want to save the NHS, get on your bike. But support from central government is weak and contradictory, and involves a fraction of the money it is spending on new roads. The major impediment to a cycling revolution is the danger of being hit by a car.

Even a switch to bicycles (including electric bikes and scooters) is only part of the answer. Fundamentally, this is not a vehicle problem but an urban design problem. Or rather, it is an urban design problem created by our favoured vehicle. Cars have made everything bigger and further away. Paris, under its mayor Anne Hidalgo, is seeking to reverse this trend, by creating a “15-minute city”, in which districts that have been treated by transport planners as mere portals to somewhere else become self-sufficient communities – each with their own shops, parks, schools and workplaces, within a 15-minute walk of everyone’s home.

This, I believe, is the radical shift that all towns and cities need. It would transform our sense of belonging, our community life, our health and our prospects of local employment, while greatly reducing pollution, noise and danger. Transport has always been about much more than transport. The way we travel helps to determine the way we live. And at the moment, locked in our metal boxes, we do not live well.

U.S. Electric Vehicle Sales Soar Into 2024

U.S. EV Sales Growth reflects rising consumer demand, expanding market share, new tax credits, and robust charging infrastructure, as automakers boost output and quarterly sales under the Inflation Reduction Act drive adoption across states.

 

Key Points

It is the rise in U.S. EV sales and market share, driven by incentives, charging growth, and automaker investment.

✅ Quarterly EV sales and share have risen since Q3 2021.

✅ Share topped 10% in Q3 2023, with states far above.

✅ IRA credits and chargers lower costs and boost adoption.

 

Contrary to any skepticism, the demand for electric vehicles (EVs) in the United States is not dwindling. Data from the Alliance for Automotive Innovation highlights a significant and ongoing increase in EV sales from 2021 through the third quarter of 2023. An upward trend in quarterly sales (depicted as bars on the left axis) and EV sales shares (illustrated by the red line on the right axis) is evident. Sales surged from about 125,000 in Q1 2021 to 185,000 in Q4 2021, and from around 300,000 in Q1 2023 to 375,000 by Q3 2023. Notably, by Q3 2023, annual U.S. EV sales exceeded 1 million for the first time, a milestone often cited as the tipping point for mass adoption in the U.S., marking a 58% increase over the same period in 2022.

EV sales have shown consistent quarterly growth since Q3 2021, and the proportion of EVs in total light-duty vehicle sales is also on the rise. EVs’ share of new sales increased from roughly 3% in Q1 2021 to about 7% in 2022, and further to over 10% in Q3 2023, though they are still behind gas cars in overall market share, for now. For context, according to the U.S. Environmental Protection Agency’s Automotive Trends Report, EVs have reached a 10% market share more quickly than conventional hybrids without a plug, which took about 25 years.

State-level data also indicates that several states exceed national averages in EV sales. California, for example, saw EVs comprising nearly 27% of sales through September 2023, even as a brief Q1 2024 market share dip has been noted nationally. Additionally, 12 states plus the District of Columbia had EV sales shares between 10% and 20% through Q3 2023.

EV sales data by automaker reveal that most companies sold more EVs in Q2 or Q3 2023 than in any previous quarter, mirroring global growth that went from zero to 2 million in five years. Except for Ford, each automaker sold more EVs in the first three quarters of 2023 than in all of 2022. EV sales in Q3 2023 notably increased compared to Q3 2022 for companies like BMW, Tesla, and Volkswagen.

Despite some production scalebacks by Ford and General Motors, these companies, along with others, remain dedicated to an electric future and expect to sell more EVs than ever. The growing consumer interest in EVs is also reflected in recent surveys by McKinsey, J.D. Power, and Consumer Reports, and echoed in Europe where the share of electric cars grew during lockdown months, showing an increasing intent to purchase EVs and a declining interest in gasoline vehicles.

Furthermore, the Inflation Reduction Act of 2022 introduces new tax credits, potentially making EVs more affordable than gasoline counterparts. Investments in charging infrastructure are also expected to increase, especially as EV adoption could drive a 38% rise in U.S. electricity demand, with over $21 billion allocated to boost public chargers from around 160,000 in 2023 to nearly 1 million by 2030.

The shift to EVs is crucial for reducing climate pollution, enhancing public health, and generating economic benefits and jobs, and by 2021 plug-in vehicles had already traveled 19 billion miles on electricity, underscoring real-world progress toward these goals. The current data and trends indicate a robust and positive future for EVs in the U.S., reinforcing the need for strong standards to further encourage investment and consumer confidence in electric vehicles.
