BEIJING — Local Chinese authorities have abruptly ordered power cuts at many factories in the last week, reflecting a system trying to react to a number of directives from Beijing, and macroeconomic developments.

While a few economists have cut their forecasts on China’s GDP growth as a result, others are still waiting to see the scale of the impact.

Here’s a broad overview on how the power crunch developed:

Coal supply drops, prices surge

Back in late 2020, China stopped buying coal from Australia, once the Asian giant’s largest source of imported coal. Political tensions between the two countries have escalated after Australia supported an investigation into how Beijing handled the coronavirus pandemic.

Meanwhile, historically cold weather that winter drove up demand for coal. Some cities reportedly restricted electricity use in homes and factories.

Alongside a global surge in commodity prices, thermal coal, the primary fuel for electricity production, saw prices soar by more than 40% over 12 months to around 777 yuan per metric ton ($119.53) in December 2020 on the Zhengzhou Commodity Exchange, according to data from Wind Information.

As spring approached, central government authorities announced five-year targets for the country to achieve its publicly declared goal of reaching peak carbon emissions by 2030. China aims in the next five years to boost the share of non-fossil fuels to about 20% of energy consumption, up from about 15% currently.

Renewable energy falls off

But as China tried to shift to renewable energy, a severe drought hit the hydropower center of Yunnan province. Water-generated power declined year-on-year in July and August by more than 4% each month, according to the National Development and Reform Commission.

Wind-generated power has also slowed its growth, rising 7% in August from a year ago, down from 25.4% growth in July, the commission said.

Analysts have also said China’s climate goals in the latest five-year plan are more moderate than expected. Climate Action Tracker, an international non-profit that reviews countries’ efforts to meet Paris Agreement goals, rated China’s policies and actions as “insufficient” in a report released Sept. 15.

The bulk of electricity in China is still generated by coal. Year-on-year growth in electricity use has surged to its highest in a decade, according to data accessed through Wind.

Power rationing begins

In addition to extreme temperatures, factories are demanding more electricity as they rush to fill global orders for Chinese goods. Exports have surged by double digits amid the pandemic.

“Demand for power has risen with China’s economic recovery,” Eurasia Group analysts wrote in May. They noted that “several industrial hubs along China’s eastern coast, including Guangdong, Zhejiang, Jiangsu, and Shandong, have warned about potential temporary power supply shortages during the summer peak season.”

In June, state-backed Securities Times reported of some power restrictions in parts of the export hub of Guangdong.

Meanwhile, coal supply was falling as mines shut down in a national effort to reduce carbon emissions. The coal inventory of major power plants reached a ten-year low in August, according to Wind data.

But in mid-August, China’s economic planning agency announced that 20 regions — accounting for about 70% of China’s GDP per Nomura — failed to meet carbon-related targets, prompting local authorities to take action.

Some authorities cut electricity overnight

Some of the latest moves were quite abrupt. For example, on Sept. 23, management of a high-tech business area in Hunan province ordered power restrictions, effective immediately, according to a copy seen by CNBC. The curbs are set to last through Thursday, the day before China’s National Day holiday that runs Oct. 1 to 7.

On Sunday, state-backed Securities Times reported of major power cuts for factories in Guangdong’s manufacturing hub of Dongguang city for the same week. The report also noted sudden power outages in many parts of northeast China, including residential areas in Liaoning province.

“The power outage means products cannot be delivered on time,” said Wen Biao, general manager at Qianhe Technology Logistics Co. in Shenzhen, Guangdong province. He said the situation is the same in Shanghai and the port city of Ningbo.

The drop in production has cut demand for shipping overseas, and prices for shipping to the U.S. West Coast have dropped to $9,000 per container, down from $15,000, he said, noting the declines began Sept. 24.

In all, Reuters reported that more than 10 provinces and regions have restricted power use.

For context, Guangdong province accounts for about 23% of China’s exports by value, while Liaoning accounts for 1.6%, according to official data for January to August.

The abrupt power cuts have also given foreign businesses pause on whether to invest more in China-based supply chains. Some businesses that had planned investments of tens of millions of U.S. dollars in China are now looking at Southeast Asia instead, said Johan Annell, partner at consulting firm Asia Perspective.

This week, China’s State Grid and National Development and Reform Commission pledged to ensure power, especially for residents, and said they would take measures such as allowing greater production of coal and increasing coal imports.

The commission said power demand this winter could exceed the peak levels of this past summer and winter.

Thermal coal prices have nearly doubled this year, and traded just over 1% lower around 1,319.80 yuan per metric ton as of midday Thursday.

Economic impact

The shock to many Chinese factories comes as investors worry about fallout in the massive real estate sector as indebted property giant Evergrande warns of default. Together with related industries like construction, real estate accounts for about a quarter of China’s GDP, according to Moody’s.

After the industry’s roughly two decades of rapid, debt-fueled expansion, regulators have stepped in with tighter rules on how much developers can borrow.

When it comes to the economic impact, Dan Wang, Shanghai-based chief economist at Hang Seng China, said she would “focus more on the restrictive policies in the property market.”

She attributed the power curbs mostly to an inability of authorities to adjust the electricity price, which is largely set by the state. Wang said factories’ rush to fill global demand has also created overcapacity.

“The impact from the power restriction is equivalent to a natural disaster,” she said.

Some economists expect a more severe impact. Among major investment banks, Nomura cut its China GDP forecast on Friday, followed by Goldman Sachs on Tuesday.

“The power cuts by themselves may not be significant enough, but combined with the property sector slowdown and regional Covid outbreaks, they do make me worry more about GDP growth in Q4,” said Zhiwei Zhang, chief economist at Pinpoint Asset Management. “I have lowered my forecast for Q4 to around 4% from 5%, with risk on the downside.”

Economists at other financial institutions have mostly held off on forecast cuts and are waiting to see how significant the drop in production is.

Also weighing on growth is a crackdown on major internet technology companies for alleged monopolistic practices. A sudden order in July that after-school tutoring companies restructure as non-profits has put hundreds of thousands of jobs — and incomes — in question.

Consumer spending, a major driver of Chinese economic growth, has also been sluggish since the pandemic as Covid-related restrictions have kept many people from traveling and eating out.

Fast charging just got sleeker: Delta’s 50kW Wallbox launches in US

Fast charging just got sleeker: Delta's 50kW Wallbox launches in US

Fremont, California-based Delta Electronics just rolled out a sleek new 50kW DC Wallbox charger that’s designed for tight spaces at ACT Expo 2025.

This charger packs a punch in a surprisingly slim, 10-inch-thick, and lightweight (just 225 pounds!) casing that can be wall-mounted or set up on a pedestal. It’s specifically designed for tight spaces like urban parking lots, busy corporate campuses, or crowded fleet operation hubs.

Delta plans to manufacture these 50kW DC Wallbox chargers in Plano, Texas, keeping it local and supporting the rapid EV infrastructure growth across North America.

A 50 kW charger is at the low end of Level 3 fast charging speed, because you don’t always need to charge your car in 25 minutes. It’s the ideal charging speed for shopping, lunch, or seeing a film. Eng Taing, Delta’s senior VP and GM of energy & telecom Infrastructure, says, “Our focus is on seamlessly integrating high efficiency charging into the diverse scenarios of everyday life, including commercial operations, not just maximizing power output.”

With a 97% efficiency rate, the Wallbox can juice up two EVs simultaneously using either CCS1 or NACS connectors. Plus, the 23-foot cable makes it easy to accommodate nearly any parking layout, eliminating headaches during installation.

Delta’s vertical integration approach means it handles everything from design to manufacturing. But it doesn’t stop at hardware; the charger also connects to Delta’s IoT platform, offering remote diagnostics, predictive maintenance, and over-the-air updates. That hopefully means fewer disruptions and smoother operations for fleet managers and EV users.

Used EV prices fell 40%, and buyers are searching like never before

Used EV prices fell 40%, and buyers are searching like never before

Used EVs

More car buyers are hunting for used EVs – CarMax says searches filtered by “electric vehicle” have nearly doubled since January 2022.

CarMax saw EV searches surge in March 2022 and again in June 2024. The first spike lined up with the gas price shock after Russia invaded Ukraine, and the second came right as the Biden administration rolled out its $4,000 federal tax credit for used EVs.

The online used car marketplace’s Spring 2025 Electric Vehicle Consumer Report shows just how far used EV prices have tumbled, down over 40% between January 2022 and February 2025. By comparison, prices for gas cars, hybrids, and plug-in hybrids only slipped about 12% over the same period.

For the third year running, the Tesla Model 3 and the Model Y were in the No. 1 and No. 2 slots, respectively, from September 1, 2024, to February 28, 2025. The Chevy Bolt jumped into third place from its previous spot at No. 7 in 2024 and 2023. The Ford F-150 Lightning (7) and the Rivian R1T (10) made the top 10 for the first time, while the Tesla Model S and the Audi e-tron dropped out. The Hyundai Ioniq 5 and Nissan Leaf were at Nos. 5 and 6, and the Volkswagen ID.4 (4), Nissan LEAF (6), and the Ford Mustang Mach-E (9) made the list for the third year in a row.

What people are trading in

For the first time ever, more people are ditching sedans and coupes for EVs than SUVs. CarMax says sedans and coupes made up 44% of all EV trade-ins, up from 36% in 2024 and just 29% the year before. It’s a clear sign that the EV switch is picking up speed across more than just SUV drivers.

When customers traded in sedans for EVs during this report’s measurement period, the most common EVs they purchased were the Tesla Model 3, Tesla Model Y, and Chevy Bolt EUV. 

The top traded-in model for an EV at CarMax was the Tesla Model 3, and those who traded in a Model 3 usually went for a Model Y. The rest of the top five include the Honda Civic and Accord, the Nissan LEAF, and the Toyota Prius. The Ford F-150 truck, the top trade-in alongside the Accord in the 2024 report, dropped off the list.

Since this is CarMax’s report, it’s of course based on data sourced from its 250 stores across the US. In 2025, Oregon beat California to become the state with the highest percentage of EV sales compared to each state’s total sales at CarMax. California has previously held the top ranking since 2023. 

The West Coast continued to dominate when it came to used EV sales. California and Washington were in second and third place, respectively. Nevada and Arizona were fourth and sixth, while Utah and New Mexico (new to the top 10 list this year) held spots five and seven. On the East Coast, New York (10) appeared on the list for a second time, dropping two spots from No. 8 in 2024. 

The newcomers include Minnesota, which jumped 24 spots in a year to No. 8, and New Jersey, which moved up six slots to No. 9.

EcoFlow RIVER 2 Pro Portable Power Station

EcoFlow launches multi-day flash offers on DELTA and RIVER power stations + EcoCredits purchase from $1

As we approach the end of EcoFlow’s ongoing Mega Sale through April 25, the brand has launched its last and longest flash sale offers, taking up to 48% off three units while also offering a major EcoCredits purchase opportunity. Alongside the return of the DELTA Pro 3 bundle we saw on Friday, you can now grab the RIVER 2 Pro Portable Power Station for $349 shipped. Normally fetching $599 outside of discounts, we first saw it come down to this rate during similar flash offers in the first phase of this sale. It’s returning as a second-chance opportunity for $250 in savings, giving you a solid traveling companion at the best rate we have tracked. It’s also beating out the pricing we’re seeing from Amazon by $10.

A more ample backup solution among the brand’s RIVER series, the RIVER 2 Pro is ideal for short-term needs at campsites, on road trips, and the like, providing you with a 768Wh LiFePO4 capacity to cover your essential devices and appliances. Through its eight output ports it can deliver up to 1,600W of power, with X-boost tech allowing it to “run 80% of home appliances.” It’s a great option for those who often make last-minute plans too, as plugging it into a wall outlet regains the battery in about 70 minutes, with it also having the options for USB-C and car port recharging, as well as a max 220W solar input, which can put it back at full in 3.5 hours to 4.5 hours in sunny conditions.

Aiper Surfer S2 Solar Pool Skimmer

Keep floating debris out of your pool with Aiper’s Surfer S2 solar skimmer back at its $320 low

Through its official Amazon storefront, Aiper is offering its latest Surfer S2 Solar Pool Skimmer for $319.98 shipped. Only on the market for a few months now, it usually carries a $540 price tag, which we first saw drop to this same rate at the top of February, which repeated last month in Amazon’s Big Spring Sale, and has otherwise kept between $340 and $400. You can pick one up while the $220 in savings last for your pool at the lowest price we have tracked, with the price also matching direct from Aiper’s website.

Building upon the success of its predecessor, Aiper’s second-generation Surfer S2 pool skimmer has been upgraded with features like the DebrisGuard anti-leak design, an improved brushless motor, an expanded suction inlet, and a 150-micron filtration system – all to provide better performance when collecting small and large debris alike from your pool’s surface. It’s also been given a larger battery that ramps up its runtime to 35 hours, with recharging available through the onboard solar panel for sunny days or its DC adapter as a backup option.

Working alongside the brand’s algorithms, it’s been equipped with dual dToF sensors to improve its obstacle avoidance – plus, there are even four retractable anti-standing columns to keep it from getting stuck on pool steps as it works. Should the columns fail to impede any such situations, the programming here knows to use its automatic self-rescue capabilities to get it back into the water to continue on its routines. There are the usual smart controls through the companion app that you’d expect, allowing you to monitor and adjust settings with the added bonus of being able to manually steer it.

Be sure to also check out the ongoing discounts across Aiper’s robotic pool cleaners that work right alongside the above pool skimmer to keep your pool clear and swim-ready, as well as the first discount we’re seeing on the new HydroComm 24/7 Smart Pool Monitor that provides 5-in-1 testing for your pool’s pH, ORP, EC, TDS, and temperature, as well as coming solar-powered.

Today’s deal is a 25% markdown off the going rate, saving you $42 while equipping your arsenal with the latest of the brand’s 12-inch compact chainsaws.

Coming in a more compact form, this 40V Greenworks chainsaw makes a reliable companion for firewood needs at home or while camping, as well as storm cleanup with hurricane season on the horizon. Powered by the included 2.0Ah battery, it sports a 12-inch bar and chain with an auto-oiler to ensure everything remains lubricated and running smoothly, delivering up to 50 cuts on a single charge. It weighs in at just six pounds, making it easy to operate for most users, complete with a safety lock and push-button start to save you time and energy over the frustrations caused by pull-strings.
