The primary time I heard the time period “digital energy crops,” I used to be reporting on how excessive warmth waves in 2022 had overwhelmed the Chinese language grid and led the federal government to limit electric-vehicle charging as an emergency resolution. I used to be informed on the time that digital energy crops (VPPs) might make grid breakdowns like that much less more likely to occur once more, however I didn’t have an opportunity to delve in to study what that meant.
When you, like me, are uncertain how an influence plant may be digital, my colleague June Kim simply revealed an insightful article explaining the know-how and the way it works. For this week’s e-newsletter, I took the possibility to ask her some extra questions on VPPs. It seems the know-how has a very good synergy with the EV trade, which is why the Chinese language authorities has began to spend money on VPPs.
“VPPs are mainly simply aggregations of distributed vitality assets that may steadiness electrical energy on the grid,” June says—assets together with electric-vehicle chargers, warmth pumps, rooftop photo voltaic panels, and residential battery packs for energy backups. “They’re working in coordination to switch the perform of a centralized coal plant or fuel plant … but additionally add an entire host of different functionalities which are helpful for the grid,” she says.
To essentially benefit from these assets, VPPs introduce one other layer: a central good system that coordinates vitality consumption and provide.
This technique permits utility corporations to deal with occasions of upper vitality demand by making changes like shifting EV cost time to 2 a.m. to keep away from peak hours.
The US authorities is working to triple VPP capability by 2030, June says. That capability is equal to 80 to 160 fossil-fuel crops that don’t need to be constructed. “They anticipate that EV batteries and the EV charging infrastructure are going to be the largest think about build up this extra VPP capability,” she says.
Contemplating the numerous influence that EVs have on the grid, it’s no shock that China, the place an EV revolution is going down sooner than in every other nation, has additionally turned its consideration to VPPs.
By the top of 2023, there have been over 20 million EVs in China, nearly half the worldwide whole. Collectively, these vehicles can devour monstrous quantities of vitality—however their batteries may also be an emergency backup supply. The ability scarcity that occurs in China nearly each summer time is an pressing reminder that the nation wants to determine incorporate these tens of millions of EVs into the present grid.
Fortunately, there are already some strikes on this space, each from the Chinese language authorities and from Chinese language EV corporations.
In January 2024, China’s Nationwide Growth and Reform Fee, the highest financial planning authority, launched a blueprint for integrating EV charging infrastructure into the grid. The nation plans to start out pilot applications with dynamic electrical energy pricing in just a few cities: decrease costs late at evening can incentivize EV house owners to cost their automobiles when the grid is just not harassed. The objective is that not more than 40% of EV charging will happen outdoors these “trough hours.” There may also be a batch of bidirectional charging stations in private and non-private areas. At these chargers, batteries can both draw electrical energy from the grid or ship it again.
In the meantime, NIO, a number one Chinese language EV firm, is reworking its personal charging networks. Final month, 10 NIO charging stations opened in Shanghai that enable automobiles to feed vitality again into the grid. The corporate additionally has over 2,000 battery-swapping stations throughout the nation. These are splendid vitality storage assets for the VPP community. A few of them have already been linked to VPP pilot applications in jap China, the corporate stated in July 2023.
One of many key obstacles to adoption of VPPs is getting folks to enroll to take part. However there’s a compelling reward on provide: cash.
If the reverse-charging infrastructure grows bigger, tens of millions of Chinese language EV house owners might make somewhat revenue by charging on the proper occasions and promoting electrical energy at others.
We don’t know the way a lot incomes potential there’s, since these pilot applications are nonetheless of their very early phases in China. However present VPP initiatives within the US can provide some reference. Over the course of 1 summer time, a Massachusetts residence could make an estimated $550; members in a separate VPP challenge in Texas can earn an estimated $150 per 12 months. “It’s not big, however it’s not nothing,” June says.
Clearly, it’s going to take a very long time to remodel our electrical grids. However creating VPPs together with the EV charging community looks like a win-win scenario for China: it helps the nation preserve its lead within the EV trade, and it additionally makes the grid extra resilient and fewer depending on coal energy crops. I gained’t be shocked if Chinese language native governments and firms work collectively to roll out digital energy crops in earnest over the following few years.
Do you suppose China will catch up shortly on adopting digital energy crops? Inform me your ideas at zeyi@technologyreview.com.

Huaqiangbei is a neighborhood in Shenzhen referred to as a hub of home innovation and imitation. It has all the time performed a pivotal function in introducing costly merchandise (like iPhones and AirPods) to Chinese language customers, both by smuggling or by producing knockoff variations. And the launch of Apple’s Imaginative and prescient Professional has once more reminded folks of Huaqiangbei’s affect on shopper developments, in keeping with Chinese language tech columnist Wang Qingrui.
One Shenzhen-based firm, EmdoorVR, has already launched a VR headset that appears nearly an identical to the Imaginative and prescient Professional. This imitator, which is way more restricted in perform, is known as VisionSE and sells for lower than 1/10 the worth. Nevertheless, many Huaqiangbei manufacturers have but to comply with go well with, since they aren’t assured about the way forward for VR headsets. Their hesitation might be one other sign that it will likely be laborious for the Imaginative and prescient Professional to seek out as a lot acceptance as Apple’s earlier successes.

For a lot of Chinese language households, enjoying mah-jongg is a vital New Yr custom. However machines are reworking how the sport is performed: a viral video on social media reveals a mah-jongg machine with out the standard tiles. As an alternative, it shows the whole lot on 5 totally different screens. It additionally routinely voices the strikes and calculates the outcomes. Not many individuals within the feedback are impressed. Mah-jongg is “99% about feeling the tiles,” says one.
