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.

Enbridge, a Canadian energy company, just announced it’s moving forward with an 815-megawatt (MW) solar project called Sequoia in Texas. When it’s done, it’ll be one of the largest solar farms in North America. The project’s price tag is a hefty $1.1 billion.
Enbridge’s Sequoia, around 150 miles west of Dallas, has already landed long-term power purchase agreements (PPAs) with AT&T and Toyota, ensuring most of its output is sold for years to come. This deal was highlighted in Enbridge’s third-quarter report on Friday.
Sequoia will be built in two phases, with power expected to start flowing in 2025 and 2026. Enbridge says it’s taken steps to reduce risks by securing equipment and procurement contracts in advance. Permits and purchase orders are also locked down.
Toyota’s PPA with Enbridge’s Texas solar project is part of Toyota’s broader push toward sustainability, as the automaker aims to achieve net zero by 2035 and match 45% of its purchased power with renewable electricity by 2026 as it still clings to its “diverse powertrain strategy.”
If you live in an area that has frequent natural disaster events, and are interested in making your home more resilient to power outages, consider going solar and adding a battery storage system.

NIO’s EV sales top 20,000 for the sixth straight month as new low-cost SUV shows promise
With its new electric SUV rolling out, NIO’s (NIO) sales topped the 20,000 mark again in Oct, its sixth straight month hitting the milestone.
NIO sold 20,976 vehicles last month, up 30.5% from October 2023. The NIO brand sold 16,657 vehicles, while its new “family-oriented smart vehicle brand,” Onvo, contributed 4,319 in its first full sales month.
After launching its new mid-size Onvo L60 electric SUV in September, NIO said production and deliveries are steadily ramping up.
At the end of October, NIO’s Onvo had 166 Centers and Spaces throughout 60 cities. Onvo plans to continue expanding its network to drive future growth.
NIO’s new electric SUV starts at around $21,200 (149,900) and is a direct rival to Tesla’s Model Y. The base $21K model is if you rent the battery. Even with the battery included, Onvo L60 prices still start at under $30,000 (206,900 yuan), with a CLTC range of up to 341 miles (555 km). That’s still less than the Model Y.
Tesla’s Model Y RWD starts at around $35,000 (249,900 yuan) with 344 mi (554 km) CLTC range in China.
NIO’s new Onvo brand drives higher Oct sales
NIO has often compared its new electric SUV to the Model Y, claiming it’s superior in many ways. The L60 has better consumption at 12.1 kWh/100km compared to the Model Y at 12.5 kWh/100km).
With a longer wheelbase (2,950 mm vs 2,890 mm), NIO’s electric SUV also provides slightly more interior space.
Despite the L60’s success so far, NIO believes its second Onvo model will be an even bigger hit. It could be a potential game-changer.
“If you think the L60 is good, then this new model is a much more competitive product,” NIO’s CEO William Li told CnEVPost after launching the L60. Onvo will launch a new EV every year. Following the L60, Onvo will launch a new mid-to-large-size electric SUV next year.
NIO’s leader claims the new model will be revolutionary. According to Li, it will offer even more surprises than the L60. Deliveries are planned to begin in Q3 2025.
| NIO Onvo L60 vs Tesla Model Y trims | Range (CLTC) |
Starting Price |
| NIO Onvo L60 (Battery rental) | 555 km (341 mi) 730 km (454 mi) |
149,900 yuan ($21,200) |
| NIO Onvo L60 (60 kWh) | 555 km (341 mi) | 206,900 yuan ($29,300) |
| NIO Onvo L60 (85 kWh) | 730 km (454 mi) | 235,900 yuan ($33,400) |
| NIO Onvo L60 (150 kWh) | +1,000 km (+621 mi) | TBD |
| Tesla Model Y RWD | 554 km (344 mi) | 249,900 yuan ($34,600) |
| Tesla Model Y AWD Long Range | 688 km (427 mi) | 290,900 yuan ($40,300) |
| Tesla Model Y AWD Performance | 615 km (382 mi) | 354,900 yuan ($49,100) |
Local reports suggest a six-or seven-seat electric SUV could hit the market even sooner. With rumors of a launch around Q1 2025, deliveries could happen as soon as May 2025.
According to sources close to the matter, the L60 is just a “stepping stone” with even more exciting EVs on the way. The source claimed the new six-seat option will start at around $42,100 (300,000 yuan).
