Another Tesla Megapack system was powered on this week, coming as the latest of the company’s increasing deployment of the grid-scale batteries.
Tesla and others have commissioned a $65 million battery energy storage system (BESS) project sporting 40MW/80MWh of Megapacks in Anchorage, Alaska, as detailed in press releases from Chugach Electric and the Matanuska Electric Association (MEA) this week. The site includes 24 of Tesla’s two-hour Megapack units, and it’s co-owned by Chugach Electric and the MEA, which own 75 and 25 percent of the project, respectively.
“The BESS enhances system flexibility, boosts reliability, saves fuel, and brings cutting-edge technology to the Railbelt,” wrote Arthur Miller, Chugach Electric CEO, in the release. “It’s a crucial step as we work to diversify power generation and create a more dynamic system.”

The providers are planning to use the Megapack system as a backup resource for both Chugach Electric and the MEA during times of peak power and outages. When outages and other issues are caused by interruptions to the transmission lines, problems with generating enough power to meet demand, or other load shed events, Tesla’s Megapacks will be able to instantly respond to grid needs using the company’s Autobidder AI.
The utility operators also say the site’s footprint could allow a future expansion of up to 70 MW.
“We’re excited to see this project contribute to our region’s energy future,” said Tony Izzo, MEA CEO Tony Izzo. “We understand that reliability of power is the number one priority for our co-op members, and this initiative will improve power quality from the Bradley Lake Hydro project while reducing costs and increasing generation options for the entire region.”
The project, like most BESS projects, is also expected to help increase local grid stability and to reduce the need for spinning reserves of natural gas and hydro generators. In moving from the current generators to the BESS, officials expect natural gas consumption to drop by roughly 5 percent annually for Chugach and the MEA.
Tesla has been backing energy storage projects around the world with the deployment of its Megapacks, with the company announcing and completing several new installations over the past few months. The company has also been ramping up production of the Megapack at a so-called “Megafactory” in Lathrop, California, while it’s currently nearing completion of a second Megafactory in Shanghai, China.

In addition to the grid-scale battery, Tesla also offers a home and commercial battery called the Powerwall. In the first three quarters of the year alone, Tesla Energy has deployed 20.3 GWh of battery storage products, outpacing the company’s 14.7GWh of deployments for the entirety of 2023.

Tesla Energy has introduced the Powerwall Lease in conjunction with Tesla Electric, making the service available in Texas. This new option delivers whole-home backup power using two Powerwall units for a net monthly cost of $35 after credits, accompanied by a low fixed electricity rate.
Under the lease terms, customers pay a one-time order fee of $100. The base lease payment for the two Powerwalls is approximately $122 per month during the first year, subject to a 3 percent annual escalator thereafter. Enrollment in a qualifying Tesla Electric Backup plan or Virtual Power Plant plan provides an $87 monthly credit.

This credit lowers the effective cost to roughly $35 per month plus applicable tax.

Installation of the standard system carries no additional charge. The package features Storm Watch for outage protection and allows complete management through a single Tesla application. The system supplies continuous whole-home backup capability.
The Powerwall system enables households to maintain electricity during severe storms that disrupt the utility grid. When outages occur, the batteries automatically provide seamless backup power to the home.

Tesla Storm Watch monitors weather forecasts and ensures the units are fully charged ahead of anticipated severe weather events so that power remains available throughout the disruption, keeping lights, refrigeration, and other essential systems operating without interruption.
Availability is restricted to select Texas locations where retail electric choice exists. Participants must lease exactly two Powerwall units and maintain continuous enrollment with Tesla Electric. Solar panels cannot be included under this particular lease arrangement.
The monthly credit activates automatically once the system is installed, receives permission to operate, and enrollment is confirmed. To retain the credit, customers are required to stay enrolled in Tesla Electric and fulfill all program conditions.
Nonstandard installations that involve electrical upgrades or special permitting may lead to extra expenses and might impact eligibility for the credit, so be sure to check with either your installer or Tesla to ensure you will still qualify.

Elon Musk continues to tease the unveiling event for the Tesla Roadster, a continuing trend that has grown into a bigger game of “When” for fans who have been waiting years for the car to finally enter production.
A video shared on X of the Joe Rogan Experience podcast that Musk appeared on last year, teasing the Roadster unveiling, was shared once again on the social media platform. The poster said the Roadster event will be “unforgettable.”
Musk agreed:
Yes
— Elon Musk (@elonmusk) August 12, 2026
The timing is interesting because just yesterday, Musk said that we will be getting flying cars, and for years, Tesla has hinted that it could develop a SpaceX cold gas thruster package that would help the car float or fly for a short period of time.
It would be reasonable to assume Tesla’s major delays with this unveiling event are likely caused by the company’s need to break the rules and push the envelope on nearly everything. Last July, Lars Moravy, Tesla’s VP of Vehicle Engineering, said:
-
“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind blowing. We showed Elon some cool demos last week of the tech we’ve been working on and he got a little excited.”
The latest updates that Tesla has given us are that the Roadster is in design development, and it did have several potential dates for an unveiling event this year, including April. It was then pushed to August.
However, there are no clues as to when Tesla will be ready, and fans are certainly getting frustrated with the delays.
For what it is worth, Franz von Holzhausen told Jay Leno this week that the event would be “very soon.”
We sure hope.

Tesla’s driverless Cybercab just passed a big test with State Governor
Florida’s governor rode Tesla’s Cybercab at a closed test track and called the experience impressive.
Florida Governor Ron DeSantis rode in a Tesla Cybercab on a closed test track this week and came away impressed, posting on X that the vehicle “successfully navigated all hazards — a kid running into the street, a crash with police stopping traffic, a Model S cutting us off, etc.” He called the ride “impressive.”
The stop was part of a broader event Monday at SunTrax, a 775 acre state owned proving ground in Auburndale that Florida built specifically to test autonomous and connected vehicles before they reach public roads. Standing next to a gold Cybercab, DeSantis described the car in plain terms: “You go in there and you just sit. You have a screen. There’s no steering wheel, no pedals. Clearly these things could be very beneficial.”

— Ron DeSantis (@RonDeSantis) August 11, 2026
DeSantis paired the praise with a caveat that has followed autonomous vehicles since the category existed. “You don’t want to be in an autonomous vehicle and it drives you into a ditch. That would not be good,” he said, framing safety validation as the gate before wider deployment.
SunTrax, the 2.25 mile oval which the state calls the only high speed autonomous vehicle test track in the Southeast, can simulate rain, pedestrian crossings, hills and crowded urban conditions at highway speeds, letting companies push a car past what an early public rollout would risk. Tesla, Waymo and Beep all use the facility, and Florida’s regulatory approach, among the most permissive for autonomous vehicles in the country, doesn’t require a human operator inside a fully autonomous car.

Tesla has reason to want the blessing of Florida and states beyond, as the Cybercab entered volume production at Gigafactory Texas this spring and has since self certified as SAE Level 4 under Texas law. Public road testing so far has kept a safety monitor in the passenger seat, and Florida is where Tesla has been expanding its existing Model Y based Robotaxi service instead, adding Miami in July and then Orlando and Tampa two weeks later. A closed track endorsement from a sitting governor doesn’t change any of that, but it does put Tesla’s newest hardware in front of a state that has already shown it will move fast on rules.
