Total Cost of EV Ownership: New Data Reveals Long-Term Savings

The California Independent System Operator (CAISO), the grid operator for most of the state, is increasingly curtailing solar- and wind-powered electricity generation as it balances supply and demand during the rapid growth of wind and solar power in California.

Grid operators must balance supply and demand to maintain a stable electric system. The output of wind and solar generators are reduced either through price signals or rarely, through an order to reduce output, during periods of:

Congestion, when power lines don’t have enough capacity to deliver available energy
Oversupply, when generation exceeds customer electricity demand

In CAISO, curtailment is largely a result of congestion. Congestion-related curtailments have increased significantly since 2019 because solar generation has been outpacing upgrades in transmission capacity.

In 2022, CAISO curtailed 2.4 million megawatthours (MWh) of utility-scale wind and solar output, a 63% increase from the amount of electricity curtailed in 2021. As of September, CAISO has curtailed more than 2.3 million MWh of wind and solar output so far this year.

Solar accounts for almost all of the energy curtailed in CAISO—95% in 2022 and 94% in the first seven months of 2023. CAISO tends to curtail the most solar in the spring when electricity demand is relatively low (because moderate spring temperatures mean less demand for space heating or air conditioning) and solar output is relatively high.

CAISO has increasingly curtailed renewable generation as renewable capacity has grown in California. In 2014, a combined 9.0 gigawatts (GW) of wind and solar capacity had been built in California. As of July 2023, that number had grown to 17.6 GW. Developers plan to add another 3.0 GW by the end of 2024.

CAISO is exploring and implementing various solutions to its increasing curtailment of renewables, including:

The Western Energy Imbalance Market (WEIM) is a real-time market that allows participants outside of CAISO to buy and sell energy to balance demand and supply. In 2022, more than 10% of total possible curtailments were avoided by trading within the WEIM. A day ahead market is expected to be operational in Spring 2025.

CAISO is expanding transmission capacity to reduce congestion. CAISO’s 2022–23 Transmission Planning Process includes 45 transmission projects to accommodate load growth and a larger share of generation from renewable energy sources.

CAISO is promoting the development of flexible resources that can quickly respond to sudden increases and decreases in demand such as battery storage technologies. California has 4.9 GW of battery storage, and developers plan to add another 7.6 GW by the end of 2024, according to our survey of recent and planned capacity changes. Renewable generators can charge these batteries with electricity that would otherwise have been curtailed.

China's electric carmakers are darting into Europe, hoping to catch traditional auto giants cold and seize a slice of a market supercharged by the continent's drive towards zero emissions.

Nio Inc (NIO.N), among a small group of challengers, launches its ES8 electric SUV in Oslo on Thursday - the first foray outside China for a company that is virtually unheard of in Europe even though it's valued at about $57 billion.

Other brands unfamiliar to many Europeans that have started selling or plan to sell cars on the continent include Aiways, BYD's (002594.SZ) Tang, SAIC's (600104.SS) MG, Dongfeng's VOYAH, and Great Wall's (601633.SS) ORA.

Yet Europe, a crowded, competitive car market dominated by famous brands, has proved elusive for Chinese carmakers in the past. They made strategic slips and also contended with a perception that China, long associated with cheap mass-production, could not compete on quality.

Indeed, Nio Chief Executive William Li told Reuters he foresees a long road to success in a mature market where it is "very difficult to be successful".

Chinese carmakers may need up to a decade to "gain a firm foothold" in Europe, the billionaire entrepreneur said - a forecast echoed by He Xiaopeng, CEO of electric vehicle (EV) maker Xpeng (9868.HK) who told Reuters his company needs 10 years "to lay a good foundation" on the continent.

These new players, many of which have only ever made electric vehicles, believe they have a window of opportunity to finally crack the lucrative market.

While electric car sales in the European Union more than doubled last year and jumped 130% in the first half of this year, traditional manufacturers are still gradually shifting their large vehicle ranges over to electric and have yet to flood the thirsty market with models.

"The market is not that busy yet, if you compare it with combustion-engine models where each of the major carmakers has a whole range of vehicles," said Alexander Klose, who heads the foreign operations of Chinese electric vehicle maker Aiways.

"That is where we think we have an opportunity," he added on a drive around Munich in a U5, a crossover SUV on sale in Germany, the Netherlands Belgium and France.

The U5 starts at 30,000 euros ($35,000) in Germany - below the average new car price and most local EV prices - before factoring in 9,000 euros in EV subsidies - and comes in just four colours and two trim levels to minimize costs.

'GERMAN PEOPLE BUY GERMAN CARS'
As Chinese carmakers gear up to enter Europe, they are trying out different business models, from relying on importers, low-cost retail options or building up more traditional dealerships.

The new reality that top Western carmakers like BMW (BMWG.DE) and Tesla Inc (TSLA.O) now produce cars in technological powerhouse China has likely undermined past perceptions of low quality workmanship - though they can be hard to shake.

Antje Levers, a teacher who lives in western Germany near the Dutch border, and her husband owned a diesel Chevrolet Orlando but wanted a greener option. They bought an Aiways U5 last year after plenty of research to fend off criticism for not buying local, and loves its handling and low running costs.

She said people had told her: "You can't buy a Chinese car, they're plastic and cheap and do not support German jobs." But she feels that is no longer true in a global car industry where you find German auto parts in Chinese cars and vice versa.

"German people buy German cars, so to buy a Chinese car you need to have a little courage," the 47-year-old added. "Sometimes you just have to be open for new things."

NIO LANDS IN NORWAY WITH NOMI
Nio launches its ES8 electric SUV alongside a NIO House - part-showroom, part-cafe and workspace for customers in the capital of Norway, a country that's also the initial base for Xpeng.

Norwegian state support for EVs has put the country at the forefront of the shift to electric. It makes sense as a European entry point because customers are used to electric vehicles so only have to be sold on an unknown Chinese brand, said Christina Bu, secretary general of the Norwegian EV Association.

"If you go to another European country you may struggle to sell both," said Bu, adding that her organisation has talked extensively with a number of Chinese EV makers keen to learn market specifics and consumer culture before launching there.

She is uncertain, though, how consumers will react to Nio's approach of swapping out batteries for customers rather than stopping to charge them, or the carmaker's strategy of leasing rather than selling batteries to customers.

"But where the Chinese are really at the forefront is the technology," she added, referring in particular to Nomi, the digital assistant in the dashboard of Nio's cars.

NEWCOMERS' STRATEGIES DIVERGE
One size does not fit all. While Nio and Xpeng have been hiring staff building up their organizations in Norway, SAIC's MG works through a car importer to sell cars in a handful of European markets.

Aiways is trying an lower-cost approach to selling cars in Europe, though Klose says it varies by market.

In Germany, for instance, the company sells its cars through Euronics, an association of independent electronics retailers, rather than building traditional dealerships.

It aims to sell across the EU by next year and to enter the U.S. market by 2023, said Klose, a former Volvo and Ford executive.

Past failed attempts by Chinese carmakers to conquer Europe are unlikely to hurt Chinese EV makers today, as consumers have grown accustomed to electronics coming from China, he added.

Such failures included Brilliance in 2007, whose vehicle received one out of five stars in a German car crash test, damaging the brand.

"The fact there are more Chinese carmakers entering the market will also help us, as it will make Chinese brands more accepted by consumers," Klose said.

Selling cars to Europeans is a "tough business, especially if your product isn't well known," said Arnie Richters, chairman of Brussels-based industry group Platform for Electromobility.

"But if they bring a lot of innovation they have a lot of opportunity."

The California New Car Dealers Association (CNCDA) reported on November 1, 2023, that sales of battery electric cars accounted for 21.5% of new car sales in the Golden State during the first 9 months of the year and 22.3% in the third quarter. At the end of Q3 in 2022, sales of electric cars stood at 16.4%. In 2021, that number was 9.1%. So, despite all the weeping and wailing and gnashing of teeth lately about how the EV revolution is stalling, the news is pretty good, at least in California.

When hybrid and hydrogen fuel cell vehicles are included in the calculations, the figure jumps up 35.4% for all vehicles sold year to date in California. Not surprisingly this means gas-powered sales are falling in the state, with the CNCDA reporting ICE market share (including gasoline and diesel vehicles) was 64.6% so far this year, down from 71.6% in 2022 and 88.4% in 2018.

California is known as the vanguard for automotive trends in the country, with shifts in preferences and government policy eventually spreading to the rest of the country. While the state’s share of electric cars exceeds one fifth of all vehicles sold year to date, the figure for the US as a whole stands at 7.4%. California has banned the sale of gas-powered vehicles starting in 2035, although the steady increase in the sale of electric cars suggests that ban may never need to be implemented as people embrace the EV revolution.

Not surprisingly, when digging deeper into the sales data, the Tesla Model Y and Model 3 dominate sales in electric car in the state, at 103,398 and 66,698 respectively. Tesla’s overall market share of battery electric car sales is at 62.9%. In fact, the Tesla Model Y is the top selling vehicle overall in California, followed by the Model 3, the Toyota RAV4 (40,622), and the Toyota Camry (39,293).

While that is good news for Tesla, its overall market share has slipped from 71.8% year to date last year at this time. Competing models from brands like Chevrolet, BMW, Mercedes, Hyundai, Volkswagen, and Kia have been slowly eating into Tesla’s market share. Overall, in California, Toyota is the sales king with 15% of sales, followed by Tesla at 13.5%. In the second quarter, Tesla narrowly edged out Toyota for top sales in the state before sales swung back in Toyota’s favor in the third quarter.

That being said, Tesla’s sales in the state climbed by 38.5% year to date, while Toyota’s actually shrank by 0.7%. Time will tell if Tesla’s popularity with the state’s car buyers improves and it can overtake Toyota for the 2023 crown, or if other EV makers can offer better products at better prices and lure California customers who want to purchase electric cars away from the Tesla brand. Certainly, no company can expect to have two thirds of the market to itself forever.

Microgrid solar outage algorithms optimize renewable energy during blackouts using grid-forming inverters, islanding control, demand forecasting, and energy storage from batteries and EVs, improving reliability by up to 35% for resilient power sharing.

Key Points

Algorithms that island homes, forecast demand, and prioritize critical loads using storage and grid-forming inverters.

✅ Disconnects inverters to form resilient neighborhood microgrids

✅ Forecasts solar, wind, and demand; allocates energy fairly

✅ Uses EVs and batteries; boosts reliability by up to 35%

Some people who have solar panels on their roof are under the impression that they can use them to power their home in the case of an outage, but that simply is not the case. Homes do remain connected to the grid during outages, as U.S. power outage risks grow, but the devices tasked with managing solar panels are normally turned off due to safety concerns. This permanent grid connection essentially prevents homeowners from drawing on the power that their own renewable energy resources generate.

This could be about to change, however, thanks to the efforts of a team of University of California San Diego engineers who have come up with algorithms that would enable homes to share and use their power in outages by disconnecting solar inverters from the grid. Their algorithms work with the existing technology and would have the added benefit of boosting the system’s reliability by as much as 35 percent.

The genius of their work lies in the ability of the algorithm to prioritize the distribution of power from the renewable resources in outages. Their equation considers forecasts for wind and solar power generation to address clean energy intermittency challenges and the available energy storage, including batteries and electric vehicles. It combines this information with the projected energy usage of residents and the amount of energy the homes are able to produce. It can be programmed to prioritize in several different ways, the most vital of which is by favoring those who need power urgently, such as those using life support equipment. It could also prioritize those who are willing to pay extra or reward those who typically generate an energy surplus during normal operations.

Learning lessons from past outages

Lead author Abdulelah H. Habib said the engineers were inspired to find a way to use the renewable power in outages by the events of Hurricane Sandy. This storm affected more than eight million people on the nation’s East Coast, some of whom were left without power for as long as two weeks.

According to the researchers, most customers prefer sharing community-scale storage systems over having systems in each home because of the lower costs. One of the paper’s senior authors, Raymond de Callafon, said that homes that are connected together are not only more resilient in power outages but they also happen to be more resilient to price fluctuations.

Each home needs to be equipped with special circuit breakers that can be remotely controlled, while utilities would need to install some communications methods so the power systems within a particular residential cluster can communicate amongst themselves. They also need a “grid forming inverter” to help them connect to one another and manage excess solar on networks safely.

One stumbling block that will have to be overcome is the current regulations. Most states do not allow individual homeowners to sell power to other homeowners, so there would have to be some adjustments to make this a reality.

Solar power growing in popularity

Solar power’s popularity is currently on the rise, and reductions in cost as the technology improves are only expected to drive this growth even further. REC CEO Steve O’Neil told CNBC that the installation rates of solar double every two years, a trend that informs residential solar economics for homeowners even though just two percent of the planet’s electricity comes from converting sunlight to energy. This means there is plenty of room for expansion. The world’s current solar capacity is 305 gigawatts, compared to just 50 gigawatts in 2010.

In addition, he pointed out that the price of solar energy has dropped by 70 percent since the year 2010 and continues to fall; it costs around eight cents per kilowatt hour at the moment. Another factor that could boost adoption is storage improvements, driven by affordable solar batteries that expand capacity, which will allow solar energy to be used even on overcast days.

The UK energy secretary could be handed powers to fast-track connecting electricity-hungry projects, such as Jaguar Land Rover’s owner Tata’s planned electric battery factory, to the grid, under plans being discussed between government and regulators.

Amid concerns about delays of up to 15 years in hooking up large schemes, the Guardian understands the move would allow Claire Coutinho to request that energy network companies accelerate upgrades to substations and power lines to connect specific new developments.

It is understood that the government and the regulator Ofgem have told National Grid’s electricity systems operator that they are “minded” to adopt its proposals to change the model for connections, which now moves at a pace set by each network operator.

A source said: “Foreign investors need assurances that, if these things are going to be built, then they can be hooked up quickly. There are physical assets, like substations, which transmission companies will need to build or upgrade.”

The government is belatedly attempting to tackle a logjam that has resulted in some developments facing a 10- to 15-year wait for a connection to the grid. Ofgem announced on Monday plans to remove “zombie” projects from the queue to connect up to speed up those ready to produce renewable power for the grid.

Although no equivalent queue exists for those looking to take power from the grid, ministers and officials are concerned that large projects could struggle to secure final investment and proceed without guarantees over their connection to the electricity supply.

Sources said changes to the rules had been proposed with several big projects in mind: Tata’s new £4bn electric battery factory, expected to be built in Somerset; and the switch to electric arc furnaces at Britain’s biggest steelworks at Port Talbot in south Wales, also owned by the Indian group.

The £1.25bn plan from British Steel, which is owned by China’s Jingye, to replace two blast furnaces at Scunthorpe steelworks, with an electric arc furnace at the north Lincolnshire plant and another at a site in Teesside, North Yorkshire, has also formed part of the proposals. Negotiations over the closure of blast furnaces at Port Talbot and Scunthorpe are expected to lead to thousands of job losses.

All three projects are likely to involve significant investment from the UK government, alongside the companies’ overseas owners.

Britain has 10 distribution network operators, including National Grid and Northern Powergrid, which operate monopolies in their regions and handle transmission of power from the grid to end users.

Sources said the move could be announced as soon as this month, and may be included within the “connections action plan”, a broader overhaul of Britain’s network connections.

The plan, which is expected to be announced alongside the chancellor’s autumn statement next week, will rebalance the planning system to help speed up the connection of new solar and windfarms to the grid.

In a town north of London, the weather's been cloudy over the winter months. But it didn't stop this homeowner from installing solar panels in December.

On his smart metre, Kumi Thiruchelvam looks satisfied at the "0 watts" showing up under electricity. It's about 10 am, and he's not using any electricity from the grid.

Cost of installation? Between £12,000 and £13,000 (€13,500-€14,500), a fair chunk of savings, even for Thiruchelvam, who lives on a private avenue in Luton.

The investment was common sense for him following the surge in energy prices caused by the Russian invasion of Ukraine.

According to the Office of National Statistics, electricity prices in the UK had increased by 67 per cent in January 2023 compared to January 2022.

Solar power installations doubled in 2022 compared to 2021, according to MCS, the standards organisation in charge of solar installations.

"We've had a combination of soaring energy prices around the world, and then also we've increased our electricity consumption in the home through a number of reasons, including electric vehicles," says Thiruchelvam.

His family owns a big house and no less than three electric vehicles, so their electricity consumption is higher than the normal household, about 12,000 kWh per year.

Around two-thirds should now be provided by solar panels.

"We originally sought the configuration to be rear, which is where the sun comes up, but we went for the front because it spends more time in the front throughout most of the year than in the rear. Also, there's more shade in the rear with trees," he says.

To get a quote for the installation, Thiruchelvam used Otovo, a Norwegian company which recently launched in the UK.

Using their app, he can monitor the electricity generated by his photovoltaic (PV) installation from his phone. The data comes from the inverters installed in the attic.

Their role is to change the direct current generated by the solar panels into alternating current to power appliances in the house safely.

They also communicate with the grid and monitor the electricity generated.

"We went for two hybrid inverters allowing for me to use a battery in the future," says Thiruchelvam.

"But because battery technology is still evolving, I chose not to. And also I viewed at that time that we would be consuming everything we'd be generating. So we didn't. But most likely I will upgrade the system as we approach summer with batteries."
