Tesla Powerwalls to help expand Virtual Power Plant in Colorado

Colorado’s Virtual Power Plant program is about to get even bigger, with the help of Tesla’s Powerwalls.

Tesla’s Powerwalls are set to help expand a Virtual Power Plant (VPP) program in Colorado, as an announcement this week notes that the company will be partnering with two local energy providers.

In a press release on Thursday, utility provider Xcel Energy and resource management company Itron announced a partnership with Tesla to help expand the existing VPP in Colorado, dubbed the Renewable Battery Connect program. Itron will integrate its IntelliFLEX platform with Tesla’s Powerwall management system, and the partners plan to increase the number of batteries that can be used during times of peak demand, as managed by Xcel.

The IntelliFLEX Aggregator Distributed Energy Resource Management System (DERMS) is designed to let energy providers localize the management of distributed batteries, utilizing a combination of residential battery storage, solar energy, electric vehicle (EV) chargers and other management systems to help balance grid energy more efficiently.

“Our Renewable Battery Connect program creates a new VPP in Colorado and we’re proud to work with Itron and Tesla, who have proven to be trusted industry partners and align with our goals to strengthen the energy grid while maintaining reliability and advancing renewable energy,” said Emmett Romine, Xcel’s VP of Customer Energy and Transportation Solutions. “This collaboration will deliver renewable, solar energy when our customers need it most.”

Itron also says the IntelliFLEX system currently helps facilitate around three million distributed energy resource devices for 30 different utilities across the U.S. The company also says the tool will give Xcel more power to manage customers’ residential batteries to help stabilize local grids.

“Integrating our IntelliFLEX solution with Tesla Powerwall demonstrates a shared vision with a leading technology partner who is at the forefront of creating electrification solutions,” said Don Reeves, SVP of Outcomes at Itron. “Through this collaboration, we are excited to bring new capabilities to Xcel Energy as they embark on its energy transition journey.”

Tesla’s Powerwall home batteries have been utilized in markets around the world, effectively letting owners store and sell stored energy back to the electrical grid in times of peak demand, outages, and other peak use cases. This kind of distributed battery system is being piloted or run in a number of U.S. states, including California, Texas, and Massachusetts, and in a few other countries and territories.

The company currently builds Powerwalls at its Gigafactory in Nevada, and the facility in November celebrated building over 1,000 of the home batteries in a single day as it continues to ramp production. In October, Tesla also said that it had over 100,000 Powerwalls participating in its VPP programs worldwide.

Tesla is ramping its real-world tests of the Cybercab, with multiple sightings of the autonomous two-seater being reported across social media this week. Based on videos of the vehicle that have been shared online, it appears that Cybercab tests are underway across multiple states.

Recent Cybercab sightings

Reports of Cybercab tests have ramped this week, with a vehicle that looked like a production-ready prototype being spotted at Apple’s Visitor Center in California. The vehicle in this sighting was interesting as it was equipped with a steering wheel. The vehicle also featured some changes to the design of its brake lights.

The Cybercab was also filmed testing at the Fremont factory’s test track, which also seemed to involve a vehicle that looked production-ready. This also seemed to be the case for a Cybercab that was spotted in Austin, Texas, which happened to be undergoing real-world tests. Overall, these sightings suggest that Cybercab testing is fully underway, and the vehicle is really moving towards production.

Production design all but finalized?

Recently, a near-production-ready Cybercab was showcased at Tesla’s Santana Row showroom in San Jose. The vehicle was equipped with frameless windows, dual windshield wipers, powered butterfly door struts, an extended front splitter, an updated lightbar, new wheel covers, and a license plate bracket. Interior updates include redesigned dash/door panels, refined seats with center cupholders, updated carpet, and what appeared to be improved legroom.

There seems to be a pretty good chance that the Cybercab’s design has been all but finalized, at least considering Elon Musk’s comments at the 2025 Annual Shareholder Meeting. During the event, Musk confirmed that the vehicle will enter production around April 2026, and its production targets will be quite ambitious.

Tesla gets a win in Sweden as union withdraws potentially “illegal” blockade

As per recent reports, the Vision union’s planned anti-Tesla action might have been illegal.

Swedish union Vision has withdrawn its sympathy blockade against Tesla’s planned service center and showroom in Kalmar. As per recent reports, the Vision union’s planned anti-Tesla action might have been illegal. 

Vision’s decision to pull the blockade

Vision announced the blockade in early December, stating that it was targeting the administrative handling of Tesla’s facility permits in Kalmar municipality. The sympathy measure was expected to start Monday, but was formally withdrawn via documents sent to the Mediation Institute and Kalmar Municipality last week. 

As noted in a Daggers Arbete report, plans for the strike were ultimately pulled after employer group SKR highlighted potential illegality under the Public Employment Act. Vision stressed its continued backing for the Swedish labor model, though Deputy negotiation manager Oskar Pettersson explained that the Vision union and IF Metall made the decision to cancel the planned strike together.

“We will not continue to challenge the regulations,” Petterson said. “The objection was of a technical nature. We made the assessment together with IF Metall that we were not in a position to challenge the legal assessment of whether we could take this particular action against Tesla. Therefore, we chose to revoke the notice itself.”

The SKR’s warning

Petterson also stated that SKR’s technical objection to the Vision union’s planned anti-Tesla strike framed the protest as an unauthorized act. “It was a legal assessment of the situation. Both for us and for IF Metall, it is important to be clear that we stand for the Swedish model. But we should not continue to challenge the regulations and risk getting judgments that lead nowhere in the application of the regulations,” he said.

Vision ultimately canceled its planned blockade against Tesla on December 9. With Vision’s withdrawal, few obstacles remain for Tesla’s long-planned Kalmar site. A foreign electrical firm completed work this fall, and Tesla’s Careers page currently lists a full-time service manager position based there, signaling an imminent opening.

Tesla Semi program Director teases major improvements

Tesla Semi Program Director Dan Priestly teased the major improvements to the all-electric Class 8 truck on Thursday night, following the company’s decision to overhaul the design earlier this year.

Priestley said he drove the Semi on Thursday, and the improvements appear to be welcomed by one of the minds behind the project. “Our customers are going to love it,” he concluded.

The small detail does not seem like much, but it is coming from someone who has been involved in the development of the truck from A to Z. Priestley has been involved in the Semi program since November 2015 and has slowly worked his way through the ranks, and currently stands as the Director of the program.

Tesla Semi undergoes major redesign as dedicated factory preps for deliveries

Tesla made some major changes to the Semi design as it announced at the 2025 Annual Shareholder Meeting that it changed the look and design to welcome improvements in efficiency.

Initially, Tesla adopted the blade-like light bar for the Semi, similar to the one that is present on the Model Y Premium and the Cybertruck.

Additionally, there are some slight aesthetic changes to help with efficiency, including a redesigned bumper with improved aero channels, a smaller wraparound windshield, and a smoother roofline for better aero performance.

All of these changes came as the company’s Semi Factory, which is located on Gigafactory Nevada’s property, was finishing up construction in preparation for initial production phases, as Tesla is planning to ramp up manufacturing next year. CEO Elon Musk has said the Semi has attracted “ridiculous demand.”

The Semi has already gathered many large companies that have signed up to buy units, including Frito-Lay and PepsiCo., which have been helping Tesla test the vehicle in a pilot program to test range, efficiency, and other important metrics that will be a major selling point.

Tesla will be the Semi’s first user, though, and the truck will help solve some of the company’s logistics needs in the coming years.
