Why Lennar is betting on a startup building backup batteries for Texas homes
In a warming world with increasingly extreme weather events, homeowners are turning to backup batteries for relief and peace of mind. But the backup only lasts only so long, and there’s a bigger problem at play: aging power grids.
Enter the virtual power plant, managed through a cloud-based system. It’s a fertile market for a number of companies as consumers look for more reliability, especially in areas prone to extreme temperatures and storms.
Base Power, headquartered in Austin, Texas, is a virtual power plant and hardware company that provides battery backup to homeowners. The startup manages the batteries, and virtually controls the power that’s going in and out.
“We install our batteries on our customers’ homes. When the grid is up and running, we use those batteries to support the power grid,” said Base CEO Zach Dell. “When the grid goes out, our customers get those batteries to back up their home. We’re also able to save our customers on the order of 10 to 20% a month on their electricity bills.”
Unlike Tesla and Enphase, Base doesn’t sell home backup batteries. Rather, it rents the batteries to homeowners, providing the hardware, software, installation, operations and electricity. Essentially, it’s a battery-based energy company.
“We own and operate it,” Dell said. “We handle all the maintenance. We take care of the system like it’s ours.”
That control allows Base to manipulate how the battery is used, specifically accessing cheaper power and passing that savings on to the consumer. Base charges the battery from the grid when demand is low, typically during overnight hours. When demand is at its peak — summer evenings and winter mornings — Base sells power, discharging the battery to support the grid.
For an upfront fee of $595 and then about $19 a month, homeowners get access to reliable power, provided by Base. That power is generated by several sources, including wind, solar, natural gas and coal. About half of Base’s customers have solar, according to the company, which lowers their costs even more and allows them to sell that power back to Base.
A company spokesperson said Base compensates customers for the power they sell back, calculated as the real-time wholesale energy price plus an additional 3 cents per kilowatt hour. Buyback rates may vary depending on market conditions and other factors.
Base is now serving one of the nation’s largest homebuilders, Lennar, which is also an investor. Base installs batteries during the construction process in roughly 20 Lennar outage-prone communities in Texas.
Stuart Miller, Chairman and co-CEO of Lennar, said it’s not just about making money.
“It’s, are we going to be able to improve the overall stature of the home building business, as it seeks to address the markets that are stressed and having problems?” he said. “Utilities and electricity is a part of that.”
Base has raised a total of $268 million from investors including Lennar, Thrive Capital, Valor Equity Partners, Lightspeed Venture Partners and Andreesen Horowitz.
Base recently announced its first utility partnership near San Antonio. Dell said the company hopes to soon expand outside of Texas. However, the batteries are made in China, and Dell said he expects to see an impact from tariffs.

Nexamp just pulled off something that could speed up clean energy deployment across the US – and potentially lower costs for everyone. The Boston-based solar developer just finished building three new solar farms in Maine and Massachusetts. But instead of waiting on the utility to handle all the grid hookup work, Nexamp did it themselves.
That might not sound groundbreaking at first, but in the world of renewable energy, it’s a pretty big deal. Normally, utilities are in charge of any grid upgrades and interconnection work needed before a new solar project can start sending power to homes and businesses. That process can be very slow and expensive.
Nexamp’s new approach, called “self-performance,” flips the script. It lets developers take on some of that work, like ordering and installing equipment, so they don’t have to sit around waiting for the utility to schedule it. That means solar farms can get online faster, which gets clean power to the grid sooner and keeps project costs in check.
The three projects that kicked off this self-performance effort are:
- Hartland Solar – 1.2 MW DC in Hartland, ME
- Barre Road Solar – 1.3 MW DC in New Braintree, MA
- Summit Farm Solar – 2.6 MW DC, also in New Braintree
Nexamp didn’t go rogue – they worked closely with Central Maine Power and National Grid on the interconnection designs, safety standards, and technical specs. But by handling the actual procurement and construction, Nexamp had way more control over cost, timing, and supply chain headaches.
“Self-performance lets us take much greater control over interconnection procurement and construction,” said Daniel Passarello, Nexamp’s lead consulting engineer for grid integration. “We can move much of the interconnection work forward at the same time as the solar farm build instead of treating them as separate. That helps us bring projects online faster and stay closer to budget.”
It also helps that Nexamp already has solid relationships with suppliers. Instead of going through multiple layers of utility procurement, they can go straight to the source, fast.
That kind of streamlining is exactly what the solar industry needs right now. Community solar is booming – as of the end of 2024, nearly 8 gigawatts of it have been installed across the US, according to the the Solar Energy Industries Association (SEIA), and that number is expected to almost double by 2030. But bottlenecks in the interconnection process slow things down.
Sara Birmingham, VP of state affairs at SEIA, called Nexamp’s move a step in the right direction. “We must modernize and streamline the interconnection process to keep pace with fast-growing demand,” she said. “Self-performance is one of several innovative approaches that can accelerate project timelines and lower costs, which benefits all ratepayers.”

When Genesis first previewed its full-size electric SUV, the coach doors were one of the biggest highlights. It looks like it will actually make its way into the production vehicle. A Genesis GV90 model was spotted in the US for the first time with coach doors, offering a glimpse of the upcoming ultra-luxury SUV.
Genesis GV90 spotted with coach doors in California
We got our first look at the full-size luxury SUV after Genesis unveiled the Neolun concept at the NY Auto Show last March.
Genesis said the concept was its “ultra-luxe vision of luxury SUVs,” and it wasn’t kidding. When it arrives, it will be sold as the GV90 as the brand’s new flagship vehicle.
The GV90 is not just a pretty-looking luxury SUV. It’s also loaded with Hyundai’s most advanced software and tech. According to Luc Donckerwolke, Genesis’ head of creative design, “it’s the epitome of timeless design and sophisticated craftsmanship.
Last month, we got a sneak peek of the interior after a production-ready GV90 was caught in California. Although somewhat toned down from the original concept, the cabin still featured many of the same elements.
Another Genesis GV90 was recently spotted in California, with actual coach doors. The new images from KindelAuto (via TheKoreanCarBlog) show a camouflaged vehicle with a hinge at the rear, where the coach doors will open.
Genesis said that B-pillarless coach doors are now feasible in production vehicles, like the GV90. However, don’t expect it to come standard on all models.
The feature will likely be reserved for higher-priced trims. We’ve seen other variants, featuring traditional doors, that are being tested in the US and Korea.
Genesis is expected to launch the GV90 in mid-2026. We will learn prices and final specs closer to launch, but the flagship electric SUV is set to debut on Hyundai’s new eM platform.
Hyundai said the platform is designed for EVs across all segments and will “provide a 50 percent improvement in driving range” compared to current EVs. It will also support Level 3 or higher autonomous driving capabilities and OTA software updates.

Elon Musk has finally confirmed that Tesla’s new ‘affordable’ electric car is just going to be the Model Y in a cheaper format.
Musk has ended months of speculations and misinformation, which he partly created, about Tesla’s upcoming cheaper electric vehicle model.
Since last year, Tesla has guided “launching new affordable models” in the first half of 2025.
We are past the first half of 2025, but Tesla confirmed yesterday that the “first build” of the new model was produced in June, and it will launch later this year.
During the shareholders’ call following the earnings results yesterday, Tesla was asked about what the new affordable model would look like. Tesla’s CFO, Vaibhav Taneja, initially stated that they wouldn’t disclose details about the design, but then Musk interrupted him and said, “It’s a Model Y.”
It’s hard to hear exactly on the call because he talked over Taneja, but he said, “the cat is out of the bag” and confirmed that the new vehicle is simply a Model Y.
Electrek has been reporting on this fact all year. We have known for months that Tesla’s upcoming “new affordable models” are Model 3 and Model Y with a stripped-down interior with fewer features, like no rear screen, and cheaper materials:
However, this fact was not accepted in the Tesla community because CEO Elon Musk falsely denied a report last year about Tesla’s “$25,000” EV model being canceled.
The facts are that Musk canceled two cheaper vehicles that Tesla was working on, commonly referred as “the $25,000 Tesla” in early 2024. Those vehicles were codenamed NV91 and NV92, and they were based on the new vehicle platform that Tesla is now reserving for the Cybercab.
Instead, Musk noticed that Tesla’s Model 3 and Model Y production lines were starting to be underutilized as the Company faced demand issues. Therefore, Tesla canceled the vehicle programs based on the new platform and decided to build new vehicles on Model 3/Y platform using the same production lines.
Now, only the new Cybercab is going to be based on the new unboxed platform.
During the conference call last night, Musk stated that the primary goal of the more affordable Model Y is to expand the market by making the vehicle more accessible to a broader audience. He suggested that it will go on sale in Q4.
Electrek’s Take
Finally, we can put this to rest. I think we can expect something similar to what Tesla did with the Model 3 in Mexico.
I think we can expect changes, such as using cloth materials instead of vegan leather, no rear display, no ambient lighting, and a lesser audio system.
In the case of the Model Y, Tesla may consider dropping some exterior lighting features, such as the light bars.
I wouldn’t be surprised also to see some powertrain changes. Maybe a less powerful RWD motor.
