A Stand for Solar: How a united movement helped pause CA’s solar tax proposal — at least for now
Earlier this month, a small miracle of sorts happened in California. The California Public Utilities Commission’s (CPUC) proposed new net metering rules (NEM 3.0) hit an indefinite “Pause” button. Through an email, Administrative Law Judge Kelly Hymes notified parties officially involved in its proceedings that the proposed decision on NEM 3.0 and its implementation “will not appear on the Commission’s voting meeting agenda until further notice.”
Getting to that point was nothing short of a Herculean task, and looking at the factors that may have contributed to this halt is a story worth telling. The movement that opposed the CPUC’s NEM 3.0 proposal is quite extraordinary, as it involved the combined efforts of companies such as Tesla and environmental organizations such as The Climate Center and the Environmental Working Group (EWG), to name a few. But before we get to the story of how NEM 3.0 was halted, we must look at why the proposal was controversial in the first place.
A Proposal with Heavy Backing
Initially unveiled last December, NEM 3.0 shocked climate advocates due to its proposed changes to the state’s rules on residential solar solutions. If passed, NEM 3.0 would charge solar users with a “grid participation charge” of $8/kWh of installed solar. Tesla estimated that an $8/kWh charge could add between $50-$80/month to a solar customer’s power bill. NEM 3.0 would also dramatically cut the compensation that homeowners with solar receive for the power they give back to the grid. NEM 3.0 supporters framed these proposed changes as a way for low-income families to not be burdened with the cost of maintaining the grid.
Supporters of NEM 3.0 advocated the idea that California’s existing solar rules take from the disadvantaged and give to the wealthy. Organizations such as Affordable Energy for All, whose coalition includes companies like Pacific Gas & Electric, Southern California Edison, and San Diego Gas & Electric, heavily pushed this “rich vs. poor” narrative. The CPUC’s 204-page proposal, which referenced a Lookback Study from Verdant Associates, was the same way. It argued that NEM 2.0, California’s current system, (a) negatively impacted non-participant ratepayers, (b) is not cost-effective, and (c) disproportionately harms low-income customers who are not participating in the net energy metering tariff program.

The Lookback Study had detractors from the get-go. The California Solar & Storage Association (CALSSA), the Solar Energy Industries Association (SEIA), and Vote Solar expressed their reservations about the validity and value of the study, with the groups arguing that the research does not properly evaluate the existing NEM 2.0 program. Despite these reservations, the CPUC stated in its proposal that it believes that the Lookback Study’s conclusions are sound.
“We find the Lookback Study to be a sound analysis of the NEM 2.0 tariff and that it should be used in the development of a successor tariff. CALSSA and SEIA/Vote Solar would have the Commission dismiss the study because it is ‘backward-looking.’ The evaluation of the NEM 2.0 tariff tells us whether the tariff is or is not performing as required, thus establishing a foundation for creating the successor tariff. We recognize, as SEIA/Vote Solar states, that the study does not tell the complete story. However, the Lookback Study can inform us of what not to do. Furthermore, CALSSA’s contention that the study’ assumptions are or appear flawed’ does not persuade us; CALSSA and all stakeholders have been given several opportunities to weigh in on the development and drafting of the study. A disagreement on an assumption does not equate to a flaw in the assumption,” the CPUC’s proposal read.
A Widespread Opposition
Despite the CPUC’s apparent efforts to push through with NEM 3.0, the proposal had one glaring problem: it was highly unpopular outside the initiative’s direct proponents. Electric vehicle and energy company Tesla promptly directed its Engage program on the issue, urging California residents to make their voices heard. Tesla CEO Elon Musk openly opposed the proposal on his Twitter account as well, describing it as a “bizarre, anti-environment move” by the state.
Survey results did not side with NEM 3.0, which energy research firm Wood Mackenzie believes could cut California’s solar market by half by 2024. A survey conducted by Newport Beach-based Probolsky Research revealed that California voters overwhelmingly opposed the CPUC’s proposed changes to the state’s solar rules. Among the survey’s respondents, 64% stated that they were opposed to NEM 3.0, 15% were unsure, and only 20% supported the CPUC’s proposal. Interestingly enough, every demographic group involved in the survey opposed NEM 3.0.

Teslarati chatted with Probolsky Research President Adam Probolsky, who explained that “while the survey did not look at its results by income level, nothing about the data suggests any difference based on respondents’ socioeconomic standing.” This hinted that the narrative being pushed by some NEM 3.0 supporters, which attempted to paint a picture of wealthy solar adopters taking advantage of the less fortunate, may not be that accurate after all.
To state that California made solar mainstream may not be an understatement, so it was no surprise that many in the state made it a point to fight against NEM 3.0. Over 120,000 public comments urging the state to save the solar industry were delivered to the CPUC in December, and high-profile figures spoke up against the proposal. These included former CA Governor Arnold Schwarzenegger, who flat-out called the proposal a “solar tax,” and Senator Dianne Feinstein, who made her opposition to NEM 3.0 evident. Even Hollywood and sports personalities used their voices to call for California’s solar industry not to be hobbled by NEM 3.0.
NEM 3.0 is so controversial that solar advocates outside the United States perceived the CPUC’s proposal with a certain level of disbelief. This was true for solar supporter and co-founder of FindTheVenue.pk Ali Rehman, who told Teslarati that NEM 3.0 — at least from the point of view of a renewable energy supporter outside the US such as himself — is nothing short of insane.
“People go solar because of high energy costs; energy costs are high due to negligence, not solar. Lobbyists and public relations firms re-wrote the facts and scripted the blame for higher prices not on bad – negligent – maintenence policies but on families who protect themselves from those higher prices, by going solar. The truth is that solar is for everyone and most beneficiaries are low-income and in disadvantaged communities,” Rehman said.
A Hard-Earned Pause
For now, NEM 3.0 has been paused. The CPUC’s new president, Alice Busching Reynolds, has requested additional time to “analyze the record and consider revisions” to the proposed initiative based on party comments. An email from one of the administrative judges on the commission also mentioned that Reynolds wishes to ensure that all five commissioners can participate in a session that covers arguments about the pros and cons of NEM 3.0.
It’s difficult to determine the exact factors that led to the vote on NEM 3.0 being suspended until further notice, but one cannot discount the collaborative efforts of multiple parties who worked together under the same goal. From companies like Tesla to climate organizations, initiatives that gathered the voices of solar supporters across the state and beyond seemed to have a positive effect. The Climate Center CEO Ellie Cohen highlighted this in a statement:
“This decision would not have happened without clean energy and justice advocates across California… This issue united climate activists, solar industry employees, working-class solar customers, and more to stand up for energy resilience, affordability, and equity. People across the state are increasingly demanding local, clean energy resources in the face of wildfires, public safety power shut-offs, and rising investor-owned utility rates. As the CPUC goes back to the drawing board, we urge them to craft a solar rate structure that benefits all Californians, not corporate utilities,” Cohen said.

However, Environmental Working Group (EWG) President and Bay Area resident Ken Cook told Teslarati that the battle for California’s residential solar industry is still ongoing.
“The moment to unleash the full potential of the clean energy revolution in California is upon us, and it is imperative regulators take every opportunity to embrace it. The coalition of more than 600 organizations that oppose the CPUC/utility plot to crush rooftop solar and exact a hefty solar tax on working-class families include numerous environmental justice and affordable housing organizations, labor unions and communities of faith, among others. These advocates are fighting to ensure the critical financial incentives remain in place so all California households regardless of income can afford to install solar,” Cook said.
A Battle That’s Yet to be Won
The EWG President’s comments may be accurate. Yes, NEM 3.0’s detractors scored a win by successfully having the vote on the controversial proposal delayed indefinitely. However, the CPUC can still initiate a vote on the issue in the near future. In its updated Engage page, Tesla warned its supporters that the CPUC can still push for a vote on NEM 3.0 as early as March 17. Granted, there’s momentum towards a more reasonable plan for California’s residential solar industry. Governor Gavin Newsom himself admitted that he personally thinks the proposal needs to change. Nevertheless, what lies ahead is likely an uphill battle.
“None of this means the solar tax proposal is dead… PG&E and the other big utilities are lobbying hard for the CPUC to approve it, and getting the five PUC Commissioners to reject or significantly modify it is still an uphill battle. The single most important action members of the public can take at this point is to voice opposition to the solar tax by speaking directly to the five CPUC Commissioners during the public comment period of next meeting on March 17,” Tesla wrote.
Teslarati reached out to the CPUC to inquire what its next steps would be considering the widespread opposition to NEM 3.0. The agency simply provided a link to its Net Energy Metering Revisit page, which provides an outline of the proposal, as well as documents and records related to it.
Considering the battle ahead, James (JD) Dillon, who serves as Chief Marketing Officer at Tigo Energy, urged those who have taken it upon themselves to defend California’s residential solar market to stay alert. In a comment to Teslarati, Dillon highlighted that it would be a mistake to ease the pressure now. If any, now is the time to double down and ensure that NEM 3.0 is really pushed back, or at least modified to a point where it is palatable and fair to California’s existing solar customers.
“Solar is inarguably the right thing for the long term and the solar advocates must keep pushing in the public and political arena. It would be a mistake to take the foot off the gas, as different versions of anti-solar legislation and administrative actions will continue to crop up. The utilities have a very powerful lobby and the hundreds of small businesses and thousands of homeowners that make up the solar coalition must remain vigilant,” Dillon advised.

Tesla’s newest “Folding V4 Superchargers” are key to its most aggressive expansion yet
Tesla’s folding V4 Supercharger ships 33% more per truck, cuts deployment time and cost significantly.
Tesla is rolling out a folding V4 Supercharger design, an engineering change that allows 33% more units to fit on a single delivery truck, cuts deployment time in half, and reduces overall installation cost by roughly 20%.
The folding mechanism addresses one of the least glamorous but most consequential bottlenecks in charging infrastructure: getting hardware from factory floor to job site efficiently. By collapsing the form factor for transit and unfolding into an operational configuration on arrival, the new design dramatically reduces the logistics overhead that has historically slowed Supercharger rollouts, particularly at large or remote sites where multiple units are needed simultaneously.
The timing aligns with a broader acceleration in Tesla’s network strategy. In March 2026, Tesla’s Gigafactory New York produced its final V3 Supercharger cabinet after more than seven years and 15,000 units, pivoting entirely to V4 cabinet production. The V4 cabinet itself is already a generational leap, delivering up to 500 kW per stall for passenger vehicles and up to 1.2 MW for the Tesla Semi, while supporting twice the stalls per cabinet at three times the power density of its predecessor. The folding transport innovation layers logistical efficiency on top of that technical foundation.
Tesla launches first ‘true’ East Coast V4 Supercharger: here’s what that means
Tesla Charging’s Director Max de Zegher, commenting on the V4 cabinet when it launched, captured the operational philosophy behind these changes: “Posts can peak up to 500kW for cars, but we need less than 1MW across 8 posts to deliver maximum power to cars 99% of the time.” The design philosophy has always been about maximizing real-world throughput, not just peak specs, and the folding transport upgrade extends that thinking into the supply chain itself.
Posts can peak up to 500kW for cars, but we need less than 1MW across 8 posts to deliver maximum power to cars 99% of the time.
No more DC busbar between cabinets. Power comes from a single V4 cabinet to 8 stalls. Easier to install, cheaper, more reliable.
Introducing Folding Unit Superchargers

The network is expanding rapidly on multiple fronts. The first true 500 kW V4 Supercharger on the East Coast opened in Kissimmee, Florida in March 2026, followed closely by a new site in Nashville, Tennessee. A public Megacharger for the Tesla Semi launched in Ontario, California in early March, with 37 additional Megacharger sites targeted for completion by end of year. Meanwhile, more than 27,500 Supercharger stalls are now accessible to non-Tesla EVs from brands including Ford, GM, Rivian, Hyundai, and most recently Stellantis, whose Dodge, Jeep, Ram, Fiat, and Maserati BEV customers gained access in March 2026.
As Tesla pushes toward a denser, faster, and more open charging network, innovations like the folding V4 Supercharger reflect the company’s growing focus on deployment velocity, not just hardware performance. Getting chargers to the ground faster, cheaper, and in greater volume per shipment may ultimately matter as much as the kilowatts they deliver.

Tesla’s $2.9 billion bet: Why Elon Musk is turning to China to build America’s solar future
Tesla looks to bring solar manufacturing to the US, with latest $2.9 billion bet to acquire Chinese solar equipment.
Tesla is reportedly in talks to purchase $2.9 billion worth of solar manufacturing equipment from a group of Chinese suppliers, including Suzhou Maxwell Technologies, which is the world’s largest producer of screen-printing equipment used in solar cell production. According to Reuters sources, the equipment is expected to be delivered before autumn and shipped to Texas, where Tesla plans to anchor its next phase of domestic solar production.
The move is a direct extension of a vision Elon Musk has been building for months. At the World Economic Forum in Davos this past January, Musk announced that both Tesla and SpaceX were independently working to establish 100 gigawatts of annual solar manufacturing capacity inside the United States. Days later, on Tesla’s Q4 2025 earnings call, he made the ambition concrete: “We’re going to work toward getting 100 GW a year of solar cell production, integrating across the entire supply chain from raw materials all the way to finished solar panels.”
Job postings on Tesla’s website reflect that same target, with language explicitly calling for 100 GW of “solar manufacturing from raw materials on American soil before the end of 2028.”
The urgency behind the latest solar manufacturing target is rooted in a set of rapidly emerging pressures related to AI and Tesla’s own energy business. U.S. power consumption hit its second consecutive record high in 2025 and is projected to climb further through 2026 and 2027, driven largely by the explosion in AI data centers and the broader electrification of transportation. Tesla’s own energy division, which produces the Megapack utility-scale battery storage system, has been growing rapidly, and solar supply is a critical companion component for the business to scale. Musk has argued that solar is not just a clean energy option but the only one that makes economic sense at the scale AI infrastructure demands.
Tesla lands in Texas for latest Megapack production facility
Ironically, the path to domestic solar independence currently runs through China. Sort of.
Despite Tesla’s stated push to localize its supply chain, mirrored recently by the company’s plan for a $4.3 billion LFP battery manufacturing partnership with LG Energy Solution in Michigan, Tesla still relies on China-based suppliers to keep its cost structure intact.
The $2.9 billion equipment deal underscores a tension Musk himself acknowledged at Davos: “Unfortunately, in the U.S. the tariff barriers for solar are extremely high and that makes the economics of deploying solar artificially high, because China makes almost all the solar.” Building the factory in America requires buying the machinery from the country Tesla is trying to reduce its dependence on.
Tesla named by U.S. Gov. in $4.3B battery deal for American-made cells
The regulatory pathway adds another layer of complexity. Suzhou Maxwell has been seeking export approval from China’s commerce ministry, and it remains unclear how quickly that clearance will come. Still, the market has already reacted, with shares in the Chinese firms reportedly involved in the talks surged more than 7% following the Reuters report that broke the story.
Whether Tesla can hit its 2028 target of 100GW of solar manufacturing remains an open question. Though that scale may seem staggering, especially in such a short timeframe, we know that Musk has a documented history of “always pulling it off” in the face of ambitious deadlines that may slip. But, rest assured – it’ll get done.

Tesla named by U.S. Gov. in $4.3B battery deal for American-made cells
What began as an open secret in the energy industry was confirmed by the U.S. Department of the Interior on Monday: Tesla is the buyer behind LG Energy Solution’s blockbuster $4.3 billion battery supply agreement.
What began as an open secret in the energy industry is becoming more real after the U.S. Department of the Interior named Tesla as the stakeholder in the LG Energy Solution’s blockbuster $4.3 billion battery supply agreement.
Tesla and LG Energy Solution are expanding their partnership to build a LFP prismatic battery cell manufacturing facility in Lansing, Michigan, launching production in 2027. The announcement, made as part of the Indo-Pacific Energy Security Summit results, ends months of speculation.
“American-made cells will power Tesla’s Megapack 3 energy storage systems produced in Houston, creating a robust domestic battery supply chain.”, notes a press release on the U.S. Department of the Interior website.
Tesla has long utilized China’s Contemporary Amperex Technology Co. (CATL), the world’s largest LFP battery maker, as one of its primary suppliers. That relationship made financial sense for years, considering that Chinese LFP cells were cheap, abundant, and reliable. But with escalated tariffs on Chinese imports and an increasingly growing Tesla Energy business that’s particularly reliant on LFP cells for products including its Megapack battery storage units designed for utilities and large-scale commercial projects.
The announcement of a deepened partnership between LG Energy Solution and Tesla has strategic logic for both parties. For Tesla, it secures a tariff-compliant, domestically produced battery supply for its fast-growing energy division. LGES, now producing LFP batteries in Michigan, becomes the only major supplier currently scaling U.S. production, outpacing rivals like Samsung SDI and SK On. LG Energy Solution’s Lansing plant, formerly known as Ultium Cells 3, was previously operated as a joint venture with General Motors. LGES acquired GM’s stake in May 2025 and now fully owns the site, with a production capacity of 50 GWh per year. LG Energy said the contract includes options to extend the supply period by up to seven years and boost volumes based on further consultations.
For the broader industry, the ripple effects are significant. This deal signals that domestic battery manufacturing can be financially viable and not just aspirational. Utilities, energy developers, and rival automakers will take note as American-made LFP supply becomes a competitive reality rather than a distant promise.
For consumers, the benefits will take time but are real. A more resilient, U.S.-based supply chain means fewer price shocks from trade disputes, more stable Megapack availability for the grid storage projects that reduce electricity costs, and long-term downward pressure on energy storage prices as domestic production scales.
Deliveries are set to begin in 2027 and run through mid-2030, and as grid storage demand accelerates, reliable, US-made battery supply is no longer a future ambition. It is becoming a core requirement of the country’s energy strategy.
