Tesla releases more details on Powerwall 3, confirms cheaper stack coming
Tesla has released more details about Powerwall 3, its new generation home energy storage system, and there’s some more good news.
Electrek first reported that Tesla started Powerwall 3 installations in the US despite having yet to launch the product on its website officially back in September.
As we previously reported, the biggest difference with the Powerwall 3 is a higher power output of 11.5 KW continuous and an integrated solar inverter.
Tesla CEO Elon Musk later confirmed that the new Powerwall 3 also has a massively impressive peak power output of 30 kW.
The company continued to use both the Powerwall 2+ and the Powerwall 3 based on what made the most sense for each installation and as it ramps up the new unit.
But these are just some of the improvements that the new Powerwall 3 is bringing. Tesla is still working on a few more things enabled by the Powerwall 3 technology.
Tesla has now produced a webinar for its installers about the new Powerwall 3 that revealed a few more interesting details.
Again, there’s no doubt that the power and load capacity is the biggest upgrade of Powerwall 3:
Most Powerwall 2 installations involved more than one unit, but that had to do more with the power limitations than the energy capacity. Households needed more continuous power capacity to run critical electric equipment on the battery pack.
With the same 13.5 kWh energy capacity, a single Powerwall 3 can power an average household for hours.
For those who need more energy capacity, Powerwall 3 is also going to be easier and cheaper to stack.
Tesla says that it is working on a new version of the Powerwall 3 without power inverter components to stack with a full Powerwall 3.
This new capacity means that you can combine 4 Powerwall 3s together for a power capacity of 46 kW and energy capacity of 54 kWh, but that’s a weird power-energy mix that is not ideal for most projects.
However, this upcoming new stackable units without power inverter, which Tesla calls ‘DC Expansion’, means that you can do a different configuration focused on adding more energy capacity:
A single of these units on the right (one full Powerwall and 3 ‘DC expansions’) would theoretically have a continuous power capacity of 11.5 kW and an energy capacity of 54 kWh.
The upcoming DC Expansion unit is going to be $1,000 cheaper than the Powerwall 3, which is listed at $9,300 before incentives.
In the webinar, Tesla also confirmed that Powerwall 3 is using LFP battery cells, like its Megapack.
The less energy-dense battery chemistry is ideal for stationary energy storage projects as it offers better longevity.
Tesla currently offers $500 off Powerwall orders if you place the order with a referral code. The energy storage unit is also eligible to the 30% tax credit.

Communication is now even more important to getting renewable projects off the ground, experts say
(From left) CNBC’s Steve Sedgwick moderates an IoT panel with Cenk Alper, CEO of Sabanci Holding, Christina Shim, chief sustainability officer of IBM, and Mitesh Patel, interim CEO and COO of SunCable International, at CONVERGE LIVE on March 13, 2025.
Renewable energy companies can shorten the long approval process needed for their projects by communicating better with stakeholders, according to experts.
Christina Shim, IBM’s chief sustainability officer, said sponsors need to focus on the business value — in addition to the environmental benefits — when discussing their projects.
“That being said … there are some triggering words now, depending on where you sit around the world, and I think the more that you can quantify business value for what you’re doing and tie it to, again, the business operations and business decision making, it’s only going to be more and more important,” Shim said Thursday.
“As long as the outcomes are the same, you just need to make sure that you’re communicating in an appropriate way with the right stakeholders.”
She compared it to how one might talk to a CFO, versus an investor, versus someone in procurement. “You kind of have to talk about things a little bit differently.”
Mitesh Patel, interim CEO and COO at SunCable International, agrees that adjusting communication for the right audience is crucial.
“For politicians, the voters are their constituency, not your project or not your company. You have to help them translate what benefits your project will bring to the constituents,” said Patel, whose company is developing a project to deliver solar energy from Australia to Singapore via undersea cables.
The project, called Australia-Asia PowerLink, is valued around $24 billion and expected to supply Singapore with 1.75 gigawatts of electricity — or around 15% of its electricity needs, according to the company.
The comments by Shim and Patel, who were speaking to CNBC’s Steve Sedgwick on a panel in Singapore, come as renewable energy projects often take many years to get off the ground.
A report from the Global Infrastructure hub, which is part of the World Bank’s Public-Private Infrastructure Advisory Facility, noted the complex nature of preparation needed before an infrastructure project gets underway. It put the average project preparation time at 6 years but said it can take up to 14 years if the project is not planned properly.
Cenk Alper, CEO of Sabanci Holding, a Turkish conglomerate, said the biggest obstacle to getting renewable energy projects off the ground is often regulatory.
“The biggest problem is still government — the permits. Because from licensing to making a project ready, the total time is longer than the construction time,” he said.
The situation in Europe is worse, he added, citing a project where connecting to the grid took two years.
Alper said Western countries need to streamline the approval process for renewable energy projects, noting China has embarked on more projects in the last five years than the rest of the world combined.
A new study from the REPEAT Project led by Princeton University’s ZERO Lab warns that the repeal of Inflation Reduction Act (IRA) tax credits could decimate the growing EV manufacturing sector.
The report “Potential Impacts of Electric Vehicle Tax Credit Repeal on US Vehicle Market and Manufacturing” clearly outlines the risks. The Princeton study states that repealing the IRA federal tax credits and the EPA’s clean vehicle regulations would sharply reduce EV demand.
Specifically, EV sales could drop around 30% by 2027 and nearly 40% by 2030 compared to sticking with the policies implemented by the Biden administration. That means the share of EVs among new cars sold would shrink dramatically – from about 18% to 13% by 2026 and from 40% to just 24% by 2030.
“While no one has a perfect crystal ball, this is our best attempt to survey available quantitative forecasts and develop an outlook on US EV sales,” explained the study’s project leader, Jesse D. Jenkins, assistant professor at Princeton’s Department of Mechanical & Aerospace Engineering and Andlinger Center for Energy & Environment in an email. “The report is also the only analysis I’m aware of to date that draws the connection to US manufacturing as well.”
Here’s why this matters: The report points out that repealing these policies wouldn’t just slow down EV adoption – it could seriously derail the US manufacturing renaissance now underway. Up to 100% of planned expansions for EV assembly plants could be canceled or shuttered. Battery manufacturing would also take a huge hit, with between 29% and 72% of battery cell production capacity becoming redundant by 2025. That means factories under construction or those just coming online would be at risk.
To put that into perspective, an Environmental Defense Fund report released in January found that $197.6 billion worth of investments in EV and battery manufacturing have been announced at 208 facilities around the US, with two-thirds announced since the passage of the Inflation Reduction Act in August 2022.
It’s probably a good time to point out that, in order to qualify for IRA federal tax credits, EVs must be domestically assembled, use battery components that have been substantially domestically produced, and use critical minerals produced, processed, or recycled in North America or free trade agreement countries.
Why, then, is the Trump administration torpedoing an industry that’s achieving the very thing it says it wants to achieve, which is to boost domestic manufacturing and jobs?
And let’s not forget the broader EV supply chain – materials, parts, and component suppliers across the country would also suffer, though these effects haven’t even been fully quantified yet.
Bottom line: Repealing the tax credits and regulations wouldn’t just slow down EV sales – it would threaten the jobs, investments, and communities counting on America’s EV manufacturing boom.

The Optiq, Cadillac’s most affordable EV, just got a price cut. Despite being on the market for less than two months, GM cut lease prices by nearly $100 a month. Here’s how you can snag the deal.
GM cuts lease prices on Cadillac’s most affordable EV
Compared to Cadillac’s other electric vehicles, like the Escalade IQL, which starts at over $130,000, and the Vistiq, which has a price tag of over $77,000, the Optiq already looks like a steal at about $55,000.
Cadillac’s electric SUV arrived in January with lease prices starting at $489 per month. Although this was already its cheapest SUV (gas or EV), GM is making it even more affordable this month.
The 2025 Cadillac Lyriq is now listed at just $399 for 24 months with $4,929 due at signing. In less than two months, the OPTIQ’s lease prices have fallen by $90, or almost 20%. The deal is for the 2025 Cadillac Optiq AWD Luxury 1 with an MSRP of $54,390.
Cadillac’s lease deal runs through March 31. However, there are a few limitations you should know about. The deal includes a $2,000 loyalty or conquest offer.
The fine print states you must be a lessee of a 2020 model year or newer non-GM vehicle for at least 30 days. According to online car research firm CarsDirect, this extends to 2011 and newer electric vehicles from a competitor brands such as Tesla, Rivian, Porsche, BMW, Ford, and Honda, among several others.
At 190″ long, 75″ wide, and 65″ tall, the Cadillac Optiq is about the same size as the Tesla Model Y (187″ long x 76″ wide x 64″ tall).
Powered by an 85 kWh battery pack, the electric SUV has a driving range of up to 302 miles. With 150 kW DC fast charging, the Optiq can gain up to 79 miles of range in about 10 minutes.
| 2025 Cadillac Optiq trim | Starting Price (including destination) |
Driving Range (EPA-estimated) |
| Luxury 1 | $54,390 | 302 miles |
| Luxury 2 | $56,590 | 302 miles |
| Sport 1 | $54,990 | 302 miles |
| Sport 2 | $57,090 | 302 miles |
Inside, the Optiq features a massive 33″ infotainment and “segment-leading” cargo (57 cubic feet) and second-row space.
GM has been introducing new deals on new EV models all year. Chevy’s new Equinox, Blazer, and Silverado EVs are all available with 0% APR with leases starting as low as $299 per month.
