Bidirectional charging may be required on EVs soon due to new CA law
It’s an exciting week for grid resiliency-lovers in California, as Governor Gavin Newsom followed up his earlier smart grid law and signed another law this week which may require bidirectional charging on EVs in the future – though the law has no hard timeline attached, so it may be a while before we see this happen.
Bidirectional charging refers to the capability of electric vehicles to not just take electricity from the grid to charge, but to output electricity in various forms, whether this be vehicle-to-load (plugging in devices, like the 1.8kW capability on the Kia Niro EV), vehicle-to-home (like Ford’s “Intelligent Backup Power” system), or vehicle-to-grid (like the Nissan Leaf is capable of).
While these applications may seem like a party trick, widespread use of bidirectional charging could lead to huge benefits for efficiency, grid resiliency, and enable much greater penetration of renewable electricity generation.
Most electric grids don’t really have trouble meeting the regular everyday needs of electricity consumers, it’s when big spikes happen that things get difficult. Either on a hot day when everyone is using air conditioning, or a day when electricity generation is curtailed for some reason or another, that’s when things get difficult.
And as climate change makes temperatures hotter, California’s grid is often overtaxed on the hottest summer days, which are becoming more numerous. Even worse, methane-burning fossil gas peaker plants are the highest-polluting form of electricity California consumes, and these are currently used at peak times in order to deal with high demand.
One solution to this problem is adding energy storage to the grid which can be dispatched when needed, and which can fill up when the grid is oversupplying electricity. This helps to balance out supply and demand of electricity and make everything a little more predictable.
This is why there has been a push for grid-based storage like Tesla megapacks, which represent a large source of rapidly-dispatchable energy storage.
But there’s another source of grid-connected batteries out there which was right under our nose the whole time: electric cars.
EVs, which are mostly connected to the internet anyway, could be used as a distributed energy storage device, and even called upon to help provide electricity when the grid needs it. We already see this happening with Virtual Power Plants based on stationary storage, but if cars had V2G, theoretically cars could contribute in a similar way – both saving the grid, and perhaps making their owners some money along the way via arbitrage (buying electricity when its cheap and selling it when its expensive).
The problem is, not many automakers have included V2G capabilities in their cars, and in the cars that do have it, not many manufacturers have made V2G-capable equipment, and the ones who have built it haven’t seen that many customers who are interested in spending the extra money to upgrade their electrical systems with V2G-capable equipment.
So there needs to be something to jumpstart all of that, and California thinks it might just have the thing.
New CA law might require bidirectional charging… eventually.
The idea started in 2023 when state Senator Nancy Skinner introduced a bill which would require EVs to have bidirectional charging by 2027.
As this bill made its way through the legislative process, it got watered down from that ambitious timeline. So the current form of the bill, which is now called SB 59, took away that timeline and instead gave the California Energy Commission (CEC) the go-ahead to issue a requirement whenever they see it fit.
The bill directs the CEC, the California Air Resources Board, and the California Public Utilities Commission to examine the use cases of bidirectional charging and give them the power to require specific weight classes of EVs to be bidirectional-capable if a compelling use case exists.
The state already estimates that integrating EVs into the grid could save $1 billion in costs annually, so there’s definitely a use case there, but the question is the cost and immediacy of building those vehicles into the grid.
The reason this can’t be done immediately is that cars take time to design, and while adding bidirectional charging to an EV isn’t the most difficult process, it also only really becomes useful with a whole ecosystem of services around the vehicle.
Even Tesla, which for years has touted itself a tech/energy company and sold powerwalls, inverters, solar panels and so on, is still only gradually trickling its bidirectional Powershare feature out onto its vehicles.
And that ecosystem has been a bit of a hard sell so far. It’s all well and good to tell someone they can make $500/year by selling energy to the grid, but then you have to convince them to buy a more expensive charging unit and keep their car plugged in all the time, with someone else managing its energy storage. Some consumers might push back against that, so part of CEC’s job is to wait to pull the trigger until it becomes apparent that people are actually interested in the end-user use case for V2G – otherwise, no sense in requiring a feature that nobody is going to use.
Electrek’s Take
Given all of these influences, we wouldn’t expect CA to require bidirectional charging any time soon. But it still gives the state a powerful trigger to pull if other efforts, like the recently-signed smart grid law, turn out not to be enough as California works to, grow, clean up, and make its grid more affordable all at the same time.
But having the force of law behind it could turn V2G into less of a parlor trick and more into something that actually makes a difference the way us EV nerds have been dreaming of for decades now (true story: Electrek once turned down Margot Robbie for an interview and instead talked to some engineers about V2G for an hour).
So, telling manufacturers that California may start mandating bidirectional charging soon means that those manufacturers will perhaps start taking V2G more seriously, particularly given the size and influence of CA’s car market. Even if the CEC doesn’t make it a requirement, the threat of it eventually becoming one means that EV-makers will probably start getting ready for it regardless.
There’s no real point to a single person discharging their car into the grid, but when millions of cars are involved, you could work to flatten out the famous “duck curve,” which describes the imbalance between electricity supply and demand. We hear a lot about “intermittency” as the problem with wind and solar, and grid storage as the solution to that, so being able to immediately switch on gigawatt-hours worth of installed storage capacity would certainly help to solve that problem. And we hope this law helps us get just a little closer to that potential future.

Newly published data from the Federal Energy Regulatory Commission (FERC), reviewed by the SUN DAY Campaign, reveal that solar accounted for over 75% of US electrical generating capacity added in the first nine months of 2025. In September alone, solar provided 98% of new capacity, marking 25 consecutive months in which solar has led among all energy sources.
Year-to-date (YTD), solar and wind have each added more new capacity than natural gas has. The mix of all renewables remains on track to exceed 40% of installed capacity within three years; solar alone may be 20%.
Solar was 75% of new generating capacity YTD
In its latest monthly “Energy Infrastructure Update” report (with data through September 30, 2025), FERC says 48 “units” of solar totaling 2,014 megawatts (MW) were placed into service in September, accounting for 98% of all new generating capacity added during the month. Oil provided the balance (40 MW).
The 567 units of utility-scale (>1 MW) solar added during the first nine months of 2025 total 21,257 MW and were 75.3% of the total new capacity placed into service by all sources. Solar capacity added YTD is 6.5% more than that added during the same period a year earlier.
Solar has now been the largest source of new generating capacity added each month for 25 consecutive months, from September 2023 to September 2025. During that period, total utility-scale solar capacity grew from 91.82 gigawatts (GW) to 158.43 GW. No other energy source added anything close to that amount of new capacity. Wind, for example, expanded by 11.07 GW while natural gas’s net increase was just 4.60 GW.
Between January and September, new wind energy has provided 3,724 MW of capacity additions – an increase of 28.6% compared to the same period last year and more than the new capacity provided by natural gas (3,161 MW). Wind accounted for 13.2% of all new capacity added during the first nine months of 2025.
Renewables were 88% of new capacity added YTD
Wind and solar (plus 4 MW of hydropower and 6 MW of biomass) accounted for 88.5% of all new generating capacity while natural gas added just 11.2% YTD. The balance of net capacity additions came from oil (63 MW) and waste heat (17 MW).
Utility-scale solar’s share of total installed capacity (11.78%) is now virtually tied with that of wind (11.80%). If recent growth rates continue, utility-scale solar capacity should surpass that of wind in FERC’s next “Energy Infrastructure Update” report.
Taken together, wind and solar make up 23.58% of the US’s total available installed utility-scale generating capacity.
Moreover, more than 25% of US solar capacity is in the form of small-scale (e.g., rooftop) systems that are not reflected in FERC’s data. Including that additional solar capacity would bring the share provided by solar and wind to more than a quarter of the US total.
With the inclusion of hydropower (7.59%), biomass (1.05%) and geothermal (0.31%), renewables currently claim a 32.53% share of total US utility-scale generating capacity. If small-scale solar capacity is included, renewables now account for more than one-third of the total US generating capacity.
Solar soon to be No. 2 source of US generating capacity
FERC reports that net “high probability” net additions of solar between October 2025 and September 2028 total 90,614 MW – an amount almost four times the forecast net “high probability” additions for wind (23,093 MW), the second fastest growing resource.
FERC also foresees net growth for hydropower (566 MW) and geothermal (92 MW) but a decrease of 126 MW in biomass capacity.
Meanwhile, natural gas capacity is projected to expand by 6,667 MW, while nuclear power is expected to add just 335 MW. In contrast, coal and oil are projected to contract by 24,011 MW and 1,587 MW, respectively.
Taken together, the net new “high probability” net utility-scale capacity additions by all renewable energy sources over the next three years – the Trump administration’s remaining time in office – would total 114,239 MW. On the other hand, the installed capacity of fossil fuels and nuclear power combined would shrink by 18,596 MW.
Should FERC’s three-year forecast materialize, by mid-fall 2028, utility-scale solar would account for 17.3% of installed U.S. generating capacity, more than any other source besides natural gas (39.9%). Further, the capacity of the mix of all utility-scale renewable energy sources would exceed 38%. The inclusion of small-scale solar, assuming it retains its 25% share of all solar energy, could push solar’s share to over 20% and that of all renewables to over 41%, while the share of natural gas would drop to less than 38%.
In fact, the numbers for renewables could be significantly higher.
FERC notes that “all additions” (net) for utility-scale solar over the next three years could be as high as 232,487 MW, while those for wind could total 65,658 MW. Hydro’s net additions could reach 9,927 MW while geothermal and biomass could increase by 202 MW and 32 MW, respectively. Such growth by renewable sources would swamp that of natural gas (29,859 MW).
“In an effort to deny reality, the Trump Administration has just announced a renaming of the National Renewable Energy Laboratory (NREL) in which it has removed the word ‘renewable’,” noted the SUN DAY Campaign’s executive director Ken Bossong. “However, FERC’s latest data show that no amount of rhetorical manipulation can change the fact that solar, wind, and other renewables continue on the path to eventual domination of the energy market.”

The Century is considered the most luxurious Toyota, and now it’s being spun off into its own high-end brand. Despite the rumors, the ultra-luxury brand won’t be as electric as expected.
Toyota sets new luxury brand up to fail with ICE plans
First introduced in 1967, the Century was launched in celebration of Toyota’s founder, Sakichi Toyoda’s 100th birthday.
The Century has since become a symbol of status and wealth in Japan, often used as a chauffeur car by high-profile company officials.
Toyota previewed the future of the ultra-luxury marquee at the 2025 Japan Mobility Show in October, launching it as a new standalone brand positioned above Lexus.
The new Century brand is set to rival higher-end automakers like Rolls-Royce and Bentley, but it won’t be as electric as initially expected. Toyota’s powertrain boss, Takashi Uehara, told CarExpert that the luxury brand’s first vehicle will, in fact, have an internal combustion engine.
Although no other details were offered, Uehara confirmed, “Yes, it will have an engine.” As to what kind, that has yet to be decided, Toyota’s powertrain president explained.
Like the next-gen Lexus supercar and upcoming Toyota GR GT, Uehara said the Century model could include a V8 engine.
The Century has been Toyota’s only vehicle with a V12 engine. In 2018, Toyota dropped the V12 in favor of a V8 hybrid powertrain for its third-generation.
Toyota’s Century launched its first SUV in 2023, currently on sale in Japan with a V6 plug-in hybrid system alongside the sedan.
Already widely considered the biggest laggard in the shift to fully electric vehicles, Toyota doubled down, developing a series of new internal combustion engines for upcoming models.
Century is one of the five global brands the Japanese auto giant introduced in October, along with Daihatsu, GR Sport, Lexus, and Toyota.
Electrek’s Take
It’s not surprising to see Toyota sticking with ICE for its ultra-luxury Century brand, but it will likely be a costly move.
Chinese auto giants, such as BYD and FAW Group, are quickly expanding into new segments, including high-end models under luxury brands such as Yangwang and Hongqi.
These companies are now expanding into new overseas markets, like Europe and Southeast Asia, where Japanese brands like Toyota have traditionally dominated, to drive growth.
Top luxury brands, including Porsche, BMW, and Mercedes-Benz, are already struggling to keep pace with Chinese EV brands. How does Toyota plan to compete with an “ultra-luxury” brand that still sells outdated ICE vehicles? We will find out more over the coming months and years as new sales data is released.

SparkCharge has partnered with the Massachusetts Clean Energy Center (MassCEC) and Zipcar to launch the Northeast’s first off‑grid, mobile DC fast‑charging hub for shared EVs. The goal is to bring fast, reliable EV charging infrastructure into communities without having to wait for costly or slow grid upgrades.
The hub sits at Zipcar’s maintenance facility in East Boston, an Environmental Justice community. It’s funded through MassCEC’s InnovateMass program and gives onsite mechanics the ability to quickly recharge a rotating fleet of Zipcar EVs before they’re dispatched across Greater Boston. Members and rideshare drivers who rent Zipcars will get steadier access to charged EVs.
“Electrification should never be limited by where the grid is or how long it takes,” SparkCharge founder and CEO Joshua Aviv said. “With this program in East Boston, we’re showing how fleets can deploy at scale, in any community, and deliver clean mobility today.”
At the center of the setup is SparkCharge’s Mobile Battery‑Powered Trailer, which delivers 320 kW of DC fast charging without the delays and big price tags that usually come with fixed infrastructure. The trailer can recharge from Zipcar’s existing onsite power between sessions, topping up its high‑capacity batteries without stressing the local grid. Since it avoids major grid upgrades entirely, the model is designed to deploy quickly and at zero upfront cost for fleets.
MassCEC says the project shows what community‑first fast charging can look like. “Every resident deserves access to clean, reliable transportation,” said Leslie Nash, MassCEC’s senior director of Technology‑to‑Market. “By partnering with SparkCharge and Zipcar in East Boston, we’re showing how Massachusetts is leading the way in clean transportation innovation.”
The hub also plays into Massachusetts’ push to hit its net‑zero 2050 targets. As shared mobility grows, electrifying fleets will be key to cutting emissions in dense urban corridors. This project introduces a scalable charging option to a part of Boston that is underserved by public charging, helping to keep Zipcar’s EVs reliably on the road.
“For twenty‑five years, Zipcar has been a leader in shared mobility, and we’re proud to take another step toward a more sustainable future,” said Angelo Adams, Zipcar’s president. “Working with SparkCharge and MassCEC allows us to bring fast, reliable EV charging directly to our members and rideshare drivers.”
Zipcar, which is owned by car rental company Avis Budget, announced on December 1 that it was shutting down its UK operations by December 31, 2025. An Avis Budget spokesperson stated that the reason was “to streamline operations, improve returns, and position the company for long-term sustainability and growth,” adding that “all other markets remain unaffected.”
