CA’s solar tax supporters are trying to run a “wealthy vs disadvantaged” narrative: It doesn’t have to be
A look at the California Public Utilities Commission’s (CPUC) ‘s 204-page proposal for its proposed new net metering rules (NEM 3.0), as well as the comments of the initiative’s supporters, shows something interesting. Supporters of NEM 3.0 are arguing that the current net metering rules, NEM 2.0, are practically an assault on disadvantaged households and a multi-billion subsidy for wealthy homeowners.
This narrative could be found all over the CPUC’s NEM 3.0 proposal. In the document, the commission argued that the existing net energy metering tariff “negatively impacts non-participating customers; is not cost-effective; and disproportionately harms low-income ratepayers” since homeowners without solar are being shouldered with the price of maintaining the grid. A study of the state’s policies further noted that California ratepayers spent about $3 billion a year to support net metering.
As critics of the initiative, such as Tesla and other renewable companies and organizations in the state, launched efforts to combat the NEM 3.0 proposal, organizations supporting the CPUC’s proposal have adopted a pretty similar stance. Affordable Clean Energy for All, a coalition of groups that include open NEM 3.0 backers like Pacific Gas & Electric, Southern California Edison, and San Diego Gas & Electric, has been particularly active in pushing the idea that NEM 2.0 takes from the disadvantaged and gives to the wealthy.
Kathy Fairbanks, a spokeswoman from Affordable Clean Energy for All, highlighted this recently. “It’s hypocritical that people who claim to want to help disadvantaged communities are advocating to keep a regressive policy that takes from the poor and gives to publicly-traded companies to fatten their profits, increase their stock price and shareholder wealth,” she said.
But inasmuch as a “rich vs. poor” concept is compelling, such a simplistic narrative hardly addresses the issues that critics are bringing up about NEM 3.0. While there is some argument in the idea that companies like Tesla are fighting the proposal since it is involved in the residential solar business, the fact remains that rooftop solar in California is growing fastest in working and middle-class neighborhoods. Not millionaires in their massive mansions — just regular working individuals that are learning the advantages and practicality of renewable energy.
Solar Rights Alliance Director Dave Rosenfeld mentioned this in a statement last month, as critics of NEM 3.0 delivered over more than 120,000 public comments to the California Public Utilities Commission (CPUC) and Governor Gavin Newsom. “This is where the rubber hits the road on blackouts, rising electricity bills, and air pollution. The correct path is to help millions more working and middle-class people get solar so we can keep up our progress and reject the utility profit grab that threatens to take us backwards,” Rosenfeld said.
Contrary to the idea that net metering takes from the disadvantaged and gives to the wealthy, an analysis by national grid modeling experts Vibrant Clean Energy has estimated that the continued growth of distributed energy resources (DER) such as rooftop, community solar, and energy storage, could actually save California ratepayers $120 billion over the next 30 years. “What our model finds is that when you account for the costs associated with distribution grid infrastructure, distributed energy resources can produce a pathway that is lower cost for all ratepayers and emits fewer greenhouse gas emissions,” Vibrant Clean Energy CEO Dr. Christopher Clack said.
While the CPUC seems very determined to ensure that NEM 3.0 is approved, the voices against the initiative are growing louder. Apart from Tesla CEO Elon Musk, who called the proposal “bizarre” and “anti-environment,” other notable personalities have expressed their criticism of NEM 3.0 online. These include, interestingly enough, two actors who played Marvel’s The Incredible Hulk on the big screen, Edward Norton and Mark Ruffalo, as well as basketball legend Bill Walton. California Governor Gavin Newsom also seems a bit more open-minded than the CPUC, noting that there’s more work to be done in the NEM 3.0 proposal.
“That draft plan that was recently released, I just had a chance to review, and I’ll say this about the plan: We still have some work to do… Do I think changes need to be made? Yes, I do,” Newsom recently said.
The California Public Utilities Commission may vote on its NEM 3.0 proposal as early as January 27, 2022.

Tesla’s new Megablock system can power 400,000 homes in under a month
Tesla also unveiled the Megapack 3, the latest iteration of its flagship utility scale battery.
Tesla has unveiled the Megablock and Megapack 3, the latest additions to its industrial-scale battery storage solution lineup.
The products highlight Tesla Energy’s growing role in the company, as well as the division’s growing efforts to provide sustainable energy solutions for industrial-scale applications.
Megablock targets speed and scale
During the “Las Megas” event in Las Vegas, Tesla launched Megablock, a pre-engineered medium-voltage block designed to integrate Megapack 3 units in a plug-and-play system. Capable of 20 MWh AC with a 25-year life cycle and more than 10,000 cycles, the Megablock could achieve 91% round-trip efficiency at medium voltage, inclusive of auxiliary loads.
Tesla emphasized that Megablock can be installed 23% faster with up to 40% lower construction costs. The platform eliminates above-ground cabling through a new flexible busbar assembly and delivers site-level density of 248 MWh per acre. With Megablock, Tesla is also aiming to commission 1 GWh in just 20 business days, or enough to power 400,000 homes in less than a month.
“With Megablock, we are targeting to commission 1 GWh in 20 business days, which is the equivalent of bringing power to 400,000 homes in less than a month. It’s crazy. How are we planning to do that? Like most things at Tesla, we are ruthlessly attacking every opportunity to save our customers time, simplify the process, remove steps, (and) automate as much as we can,” the company said.
Megapack 3 is all about simplicity
The Megapack 3 is Tesla’s next-generation utility battery, designed with a simplified architecture that cuts 78% of connections compared to the previous version. Its thermal bay is drastically simplified, and it uses a Model Y heat pump on steroids. The battery weighs about 86,000 pounds and holds 5 MWh of usable AC energy. Tesla engineers incorporated a larger battery module and a new 2.8-liter LFP cell co-developed with the company’s cell team.
The Megapack 3 is designed for serviceability, and it features easier front access and no roof penetrations. About 75% of Megapack 3’s total mass is battery cells, with individual modules weighing as much as a Cybertruck. It’s also tough, with an ambient operating temperature range from -40C to 60C. This should allow the Megapack 3 to operate optimally from the coldest to the hottest regions on the planet.
Production is set to begin at Tesla’s Houston Megafactory in late 2026, with planned capacity of 50 GWh per year. Additional supply will come from Tesla’s 7 GWh LFP facility in Nevada, which is expected to open in 2025, as well as with third-party partners.

Tesla Energy is the world’s top global battery storage system provider again
Tesla Energy captured 15% of the battery storage segment’s global market share in 2024.
Tesla Energy held its top position in the global battery energy storage system (BESS) integrator market for the second consecutive year, capturing 15% of global market share in 2024, as per Wood Mackenzie’s latest rankings.
Tesla Energy’s lead, however, is shrinking, as Chinese competitors like Sungrow are steadily increasing their global footprint, particularly in European markets.
Tesla Energy dominates in North America, but its lead is narrowing globally
Tesla Energy retained its leadership in the North American market with a commanding 39% share in 2024. Sungrow, though still ranked second in the region, saw its share drop from 17% to 10%. Powin took third place, even if the company itself filed for bankruptcy earlier this year, as noted in a Solar Power World report.
On the global stage, Tesla Energy’s lead over Sungrow shrank from four points in 2023 to just one in 2024, indicating intensifying competition. Chinese firm CRRC came in third worldwide with an 8% share.
Wood Mackenzie ranked vendors based on MWh shipments with recognized revenue in 2024. According to analyst Kevin Shang, “Competition among established BESS integrators remains incredibly intense. Seven of the top 10 vendors last year struggled to expand their market share, remaining either unchanged or declining.”
Chinese integrators surge in Europe, falter in U.S.
China’s influence on the BESS market continues to grow, with seven of the global top 10 BESS integrators now headquartered in the country. Chinese companies saw a 67% year-over-year increase in European market share, and four of the top 10 BESS vendors in Europe are now based in China. In contrast, Chinese companies’ market share in North America dropped more than 30%, from 23% to 16% amid Tesla Energy’s momentum and the Trump administration’s policies.
Wood Mackenzie noted that success in the global BESS space will hinge on companies’ ability to adapt to divergent regulations and geopolitical headwinds. “The global BESS integrator landscape is becoming increasingly complex, with regional trade policies and geopolitical tensions reshaping competitive dynamics,” Shang noted, pointing to Tesla’s maintained lead and the rapid ascent of Chinese rivals as signs of a shifting industry balance.
“While Tesla maintains its global leadership, the rapid rise of Chinese integrators in Europe and their dominance in emerging markets like the Middle East signals a fundamental shift in the industry. Success will increasingly depend on companies’ ability to navigate diverse regulatory environments, adapt to local market requirements, and maintain competitive cost structures across multiple regions,” the analyst added.

Tesla inks multi-billion-dollar deal with LG Energy Solution to avoid tariff pressure
Tesla has reportedly secured a sizable partnership with LGES for LFP cells, and there’s an extra positive out of it.
Tesla has reportedly inked a multi-billion-dollar deal with LG Energy Solution in an effort to avoid tariff pressure and domesticate more of its supply chain.
Reuters is reporting that Tesla and LGES, a South Korean battery supplier of the automaker, signed a $4.3 billion deal for energy storage system batteries. The cells are going to be manufactured by LGES at its U.S. factory located in Michigan, the report indicates. The batteries will be the lithium iron phosphate, or LFP, chemistry.
Tesla delivers 384,000 vehicles in Q2 2025, deploys 9.6 GWh in energy storage
It is a move Tesla is making to avoid buying cells and parts from overseas as the Trump White House continues to use tariffs to prioritize domestic manufacturing.
LGES announced earlier today that it had signed a $4.3 billion contract to supply LFP cells over three years to a company, but it did not identify the customer, nor did the company state whether the batteries would be used in automotive or energy storage applications.
The deal is advantageous for both companies. Tesla is going to alleviate its reliance on battery cells that are built out of the country, so it’s going to be able to take some financial pressure off itself.
For LGES, the company has reported that it has experienced slowed demand for its cells in terms of automotive applications. It planned to offset this demand lag with more projects involving the cells in energy storage projects. This has been helped by the need for these systems at data centers used for AI.
During the Q1 Earnings Call, Tesla CFO Vaibhav Taneja confirmed that the company’s energy division had been impacted by the need to source cells from China-based suppliers. He went on to say that the company would work on “securing additional supply chain from non-China-based suppliers.”
It seems as if Tesla has managed to secure some of this needed domestic supply chain.
