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.

Electricity demand is skyrocketing across the Middle East and North Africa, and it’s being driven by two big factors: cooling homes and businesses in extreme heat, and making seawater drinkable through desalination. A new report from the International Energy Agency (IEA) shows just how dramatic the surge is. Electricity use in the region has tripled since 2000, and it’s expected to jump another 50% by 2035. That’s like adding the current combined electricity demand of Germany and Spain.
Cooling and desalination alone are expected to account for about 40% of that growth over the next decade. Urbanization, industrialization, the electrification of transport, and the boom in data centers are also adding to the load, according to the IEA’s report, “The Future of Electricity in the Middle East and North Africa.”
Right now, natural gas and oil overwhelmingly dominate power generation in the region, making up more than 90% of electricity supply. But that mix is changing. Many countries, including Saudi Arabia and Iraq, are trying to reduce oil-fired power to free it up for export. The IEA says natural gas will likely cover half the demand growth through 2035, with oil’s share falling from 20% today to just 5%.
Renewables are on the rise, too. Solar capacity is set to increase tenfold by 2035, growing by 200 gigawatts (GW), which would boost renewables’ share of the electricity mix to around 25%, up from 6% in 2024. Nuclear power is also expected to triple over the same period.
“Demand for electricity is surging across the Middle East and North Africa, driven by the rapidly rising need for air conditioning and water desalination in a heat- and water-stressed region with growing populations and economies,” said IEA executive director Fatih Birol. “To meet this demand, power capacity over the next 10 years is set to expand by over 300 GW, the equivalent of three times Saudi Arabia’s current total generation capacity.”
Meeting that demand won’t come cheap. Investment in the power sector hit $44 billion in 2024, and it’s projected to grow another 50% by 2035. Nearly 40% of that spending is expected to go toward upgrading grids, which currently suffer losses that are double the global average.
The IEA says grid upgrades and stronger regional interconnections will be critical for electricity security. Balancing renewables will also require more energy storage, demand-side flexibility, and enough gas-fired plants to cover when solar and wind aren’t available.
Energy efficiency improvements could ease some of the strain. For example, air conditioners in the region are less than half as efficient as those in Japan. Upgrading the ACs alone could cut peak demand growth by an amount equal to Iraq’s entire current power capacity.
If countries move more slowly on diversifying their power mix, according to the report, the stakes are high. Carbon dioxide emissions would continue to rise, and oil and gas demand for electricity could increase by more than a quarter by 2035, cutting export revenues by $80 billion and raising import bills by $20 billion.

Is it just me, or do too many new vehicles look about the same? Hyundai believes it’s time to end a popular trend that nearly every EV has nowadays.
Hyundai looks past the LED lightbar for new EV design
The LED light bar has been around for a while. In the early 2000’s Xenon headlights were the hit trend, offering much brighter light while consuming less energy.
Although it was initially mainly found on luxury vehicles, Hyundai was one of the first to jump on the trend, working to make it more widely available at a lower cost.
Over the past few years, the trend has evolved into a thin LED light strip stretched across the front and sometimes the rear of the vehicle.
Since most brands are slapping it on electric vehicles, it’s become almost a status symbol of the EV movement. In early 2023, Hyundai revealed the new “EV-derived, futuristic” design for the Kona Electric, placing a heavy emphasis on the front LED lightbar.
Nowadays, nearly every vehicle, EV or gas-powered, has the popular design feature. Even Tesla hopped on the trend with the new Model Y, Model 3, and Cybertruck.
According to Hyundai’s design boss, Simon Loasby, LED lightbars are “almost at the end of their journey.” After unveiling the new Concept Three at the Munich Motor Show last week, Loasby explained to Car Magazine on the sidelines, “When is the time you need to let go [of light bars], it’s almost like the end of that.”
Although Hyundai recently added the lightbar to the Grandeur, Kona, and Sonata, Loasby said he’s “seen enough.”
“It worked at the time, and it was absolutely right, the Grandeur was the first car with a one-piece structure. The biggest thing is the cost level, you just can’t afford to do it and some customers don’t need it,” Hyundai’s design chief explained.
In China, “you must have it,” Loasby said, but in other markets, like Europe and the US, it’s not needed. Hyundai is instead focusing on differentiating itself with its unique pixel lightning, found on the IONIQ EV models.
Hyundai has already had a few copy its design, notably the Fiat Grande Panda, which Loasby joked, “thanks for copying, thanks for being inspired by us.”
It may be time for a shake-up. Loasby said, “I think we are almost at the end of journey in terms of lighting. It’s almost like chrome.”
Hyundai’s new Concept Three, which is expected to launch as the IONIQ 3 in production form, did not feature a full LED lightbar. Instead, it had an updated pixel lightning design.
Electrek’s Take
I have to agree with Loasby on this one. I must admit that at first, I was a fan of the sleek look of a nice, slim lightbar, especially at night.
The more I see it, the more it reminds me of a Toyota now. And that’s nothing against them (It is the world’s largest automaker), but should a Tesla Model Y, or even a Porsche 911, look the same as a Toyota from the front? I’ll let you determine that one.
I drive a 2023 Tesla Model 3, the last of the pre-facelift version, and was pretty bummed to see how cool the updated Model 3 looked at first. The more I see them, though, the more I like the design of the first-gen Model 3 and its wide eyes. It’s unique. Now, the Model 3 looks like any other vehicle, at least, in my opinion.
Is it time to put an end to the LED lightbar? Let us know how you feel about it below.

Zero 60, an EV charge point operator on the ChargePoint network, is bringing fast charging to a Culver’s in the Northwoods of Wisconsin. The company, founded by Faith Technologies Incorporated (FTI), will install a renewable-powered charging station in Rhinelander.
The new site sits along a state-designated Alternative Fuel Corridor at Culver’s on 620 W. Kemp St. It will feature four 160-kilowatt charging ports, giving EV drivers in northern Wisconsin reliable fast charging well beyond the state’s urban hubs.
The project is backed by the Wisconsin Department of Transportation’s first round of funding from the Wisconsin Electric Vehicle Infrastructure (WEVI) program. Wisconsin wants to ensure EV drivers can confidently travel north, knowing they won’t be stranded without chargers.
“Partnering with a well-known brand like Culver’s gives us a unique opportunity to combine Midwest hospitality with clean, convenient charging,” said Wade Leipold, executive vice president of FTI. “We’re proud to support Wisconsin’s efforts to build a robust, future-ready charging network that serves communities and travelers alike.”
Zero6 Energy is financing, owning, and operating the station, while FTI is handling the engineering, design, installation, and ongoing maintenance. Zero 60 already operates nine charging sites and has plans for many more across the US, with the first wave of stations installed in New York, California, Colorado, and Wisconsin, and more currently being developed in other states.
