A groundbreaking new Virtual Power Plant Power Purchase Agreement (VPA) provides Texans with solar panels and two 20 kWh sonnen batteries at no upfront cost.
A new sonnen storage + solar VPP for Texans
SOLRITE Energy, which finances solar and battery storage, and global battery storage manufacturer sonnen today announced the launch of their new VPA in Texas’s ERCOT market. This program offers solar and battery storage for homeowners at an affordable monthly rate, making backup power accessible for many Texans.
Here’s how it works: SOLRITE installs solar panels and sonnen batteries at eligible customer households with no upfront cost. (I’ve asked the sonnen spokesperson what the eligibility criteria are and will update this post when I hear back.) Homeowners then pay a lower-than-average rate for the solar energy they produce each month, saving them money compared to typical electricity rates in Texas.
Texans participating in the SOLRITE program pay a leading rate of 12¢ per kWh for solar energy, significantly lower than the 19-20¢ per kWh rate commonly seen in the state.
The sonnen batteries provide backup power for each home at no charge and enable Texan homeowners to join a larger virtual power plant (VPP) network. The VPP supports the Texas grid, reducing reliance on polluting power plants during times of high demand. SOLRITE and sonnen generate revenue from the energy stored in these batteries, which helps cover the cost of the equipment, and that’s what allows homeowners to use the battery systems at no cost.
Each day, the sonnen batteries in the VPP help balance the Texas grid by directing power where it’s needed most and when it’s most valuable. This reduces energy costs for everyone, whether they’re in the VPP or not, and strengthens the grid’s efficiency and resilience.
The VPP also differs from traditional solar buyback programs that send extra energy to the grid whenever it’s sunny. Instead, the sonnen battery network strategically controls when and how energy is shared with the ERCOT grid, making solar energy a more reliable power source.
Since September 2024, SOLRITE says it’s already committed over 40 megawatt-hours of residential battery power to the Texas market through this program, working with solar installers statewide.
Blake Richetta, chairman and CEO of sonnen Inc. USA said:
The bold and inventive SOLRITE introduction in the Texas market represents the most successful early-stage launch of the sonnenConnect VPP in the world.
sonnen is proud to dispatch authentic VPPs across the United States and Australia, as well as the largest behind-the-meter residential battery based VPP in the European Union – with nerve centers in Germany, Italy and Belgium, amongst other countries.
And in all of these markets, we have never seen anything like the SOLRITE Texas launch. We are so proud of the SOLRITE invention, and we are passionate to build a SOLRITE-Future for Texas.
Electrek’s Take
I belong to a virtual power plant in Vermont and have two Tesla Powerwalls, and I love being part of this program. I lease my Powerwalls for $55 a month and had to pay a couple thousand dollars to have them installed, so what sonnen and SOLRITE are offering to Texans is a really good deal.

A federal court judge in Michigan has placed the once-promising electric truck brand Bollinger Motors’ assets into receivership following claims that the company’s owners still owe its founder, Robert Bollinger, more than $10 million.
Now, Automotive News is reporting on some of the more convoluted details of the Mullen purchase deal, with Robert (for ease of distinguishing the man from the brand) claiming that Mullen Automotive owes him more than $10 million for a loan he made to the company in 2024.
Just how Robert ended up giving Mullen Automotive $10 million to take his eponymous truck brand off his hands is probably one of those capitalistic mysteries that I’ll never understand, but Mullen’s response was perfectly clear: they didn’t even bother to show up to court.

Bollinger claims that at least two suppliers are also suing Mullen for unpaid debts. As such, the Honorable Terrence G. Berg has put the Bollinger brand into receivership, and its assets have been frozen in preparation for everything being liquidated. Worse, for Bollinger, the official court filings reveal a company that is really very much doing not awesome:
The testimony and evidence—which Defendant’s counsel conceded accurately reflected Defendant’s finances—showed that Defendant is in crisis. For months Defendant has owed more than twenty million dollars to suppliers, contractors, service providers, and owners of physical space. These debts are owed to parties who are critical for Defendant’s functioning. CEO Bryan Chambers testified that Defendant was locked out of its production facilities on May 5, 2025, and that the owner of the production facilities was seeking to permanently evict Defendant. The Court heard that Defendant had been prevented from accessing its critical manufacturing accounting system for a short time at the end of April 2025, before making a partial payment to restart services.
You can read the full court decision, which I’ve embedded here, below. Once you’ve taken it all in, feel free to rush into the comments to say you told me so, since I really thought hoped the Bollinger B1 had a shot. Silly me.
Mammoth Solar, a 1.3 gigawatt (GW) solar farm in northern Indiana, is now powering into its biggest construction phase yet, cementing its place as one of the largest solar projects in the US.
The solar farm is set to increase Indiana’s solar capacity by more than 20% once it’s fully online. And with construction ramping up this month, developer Doral Renewables has given Bechtel Full Notice to Proceed on the design, engineering, and construction of three major phases of the project: Mammoth South, Mammoth Central I, and Mammoth Central II. Together, these phases will generate 900 MW of clean energy.
That’s enough electricity to power around 200,000 homes with clean energy, helping Indiana shift away from fossil fuels while boosting the local economy.
Construction is already underway, and over the next two years, Bechtel will install around 2 million solar panels, with about half of them made in the US. The company is also handling all engineering, procurement, and construction work, using its digital project management tools and autonomous tech to keep everything on track.

At the peak of the buildout, Mammoth Solar is expected to create over 1,200 jobs, with at least 15% of those set aside for apprenticeships.
Bechtel says its success will hinge on strong collaboration with local trades and vendors. The company is working closely with craft professionals and is committed to being a reliable community partner throughout construction.
Once the solar farm is complete in 2027, Doral Renewables plans to roll out agrivoltaics across the site. That means livestock grazing and crop cultivation will happen right alongside energy production, giving farmers in the area a way to keep working their land while supporting clean energy development.
If you live in an area that has frequent natural disaster events, and are interested in making your home more resilient to power outages, consider going solar and adding a battery storage system.

BYD is about to launch an even smaller EV, but this one’s a little different. It’s BYD’s first kei car. You know, those tiny vehicles that dominate Japan’s city streets? BYD’s mini EV was just spotted out in public, giving us our first real look at the upcoming kei car.
BYD’s first mini EV was spotted in public
Last week, rumors surfaced that BYD was developing its first kei car, which would compete with top-selling models from Nissan, Honda, Mitsubishi, and other Japanese brands.
Kei cars, or “K-Car,” as they are sometimes called, are a class of ultra-compact vehicles that cannot be longer than 3.4 meters (134″). To put that into perspective, BYD’s smallest EV currently, the Seagull (called the Dolphin Mini overseas), is 3,780 mm (148.8″) long.
The mini vehicles are ideal in Japan because they are so small, making it easy to get around tight city streets. They are also more affordable and efficient than larger vehicles.

BYD’s mini EV was spotted for the first time during a road test this week by IT Home (via CarNewsChina), revealing a familiar look. It has that boxy, compact look of a typical kei car with sliding side doors.

According to reports, BYD is developing a new platform for the model. It will reportedly include a 20 kWh battery, good for 180 km (112 miles) WLTC range. By using its in-house Blade LFP batteries, BYD is expected to have a cost advantage.
BYD’s upcoming mini EV is expected to start at around 2.5 million yen, or about $18,000. That’s about the same as the Nissan Sakura (2.59 million yen), Japan’s best-selling EV last year.
Last year, around 1.55 million kei cars were sold in Japan, accounting for roughly 40% of new vehicle sales. Honda’s N-Box was the top-selling kei car (EV or gas) for the third straight year.
As Nikkei reported, some are already calling BYD’s electric kei car “a huge threat.” A Suzuki dealer said, “Young people do not have a negative view of BYD. It would be a huge threat if the company launches cheap models in Japan.”

BYD already sells several electric cars in Japan, including the Atto 3 SUV, Dolphin, and Seal. Last month, the company launched the new Sealion 7 midsize electric SUV, starting at 4.95 million yen ($34,500).
Although Japan isn’t really an EV hot spot, with sales falling 33% in 2024 to just under 60,000 units, BYD sees an opportunity.

By making virtually every car component in-house, including batteries, BYD can offer EVs at such low prices while still making a profit. BYD’s cheapest and best-selling electric car, the Seagull, starts at under $10,000 (69,800 yuan) in China.
With new smart driving and charging tech rolling out, BYD’s electric cars are getting smarter and even more efficient.
Can BYD’s mini EV compete with Japanese brands? At the right price, it may have a chance. Check back soon for more on the upcoming kei car. We’ll keep you up to date with the latest.
