The Texas Public Utility Commission (PUC) is moving forward with its consideration of distributed energy resource pilot. This is prompted by Tesla’s virtual power plant (VPP) proposal. The initiative is led by Commissioner Will McAdams who shared his view on how the PUC should proceed, according to Energy Choice Matters.
Tesla’s U.S. Energy Markets Policy Lead, Arushi Sharma Frank, shared a thread on Twitter about the upcoming July 11 Aggregated Distributed Energy Resources (DERs) workshop

She also tweeted to the PUC’s Twitter account explaining that small DERs need to be recognized and registered by the Electric Reliability Council of Texas (ERCOT). You can read her full thread here.
The July 11 PUC Workshop
Commissioner Jimmy Glotfelty emphasized, “This is not a one-company pilot.” Glotfelty will most likely co-author a future memo addressing issues with McAdams forming the July 11 workshop.
Glotfelty also added that although the PUC’s focus on creating a DER was prompted by Tesla’s proposed VPP, “There’s lots of technologies out there, there’s lots of opportunities, there’s lots of different systems, so we want this to be broad and diverse … we want to understand the benefits of these different technologies.”
The workshop will consist of a group of stakeholders at the PUC and will consider key goals and objectives that they hope to accomplish. It will also discuss issues that the PUC needs to make a decision on if they want to launch the pilot.
McAdams noted that these issues included the “interchange of customers.” This means that “if there is a network of retail providers or NOIEs that’s availing themselves of the pilot, then how can customers move in-between REPs over the duration of that pilot so that they’re not locked in for a number of years under one particular plan, because that would make it unappealing to the broadest possible segment of customers.”
In addition, the following are issues that will also be discussed:
- The scale of the pilot.
- Duration. Participation of customers.
- Overall reliability.
- Includes the operational interconnection and export dynamics and how the PUC overcomes these two challenges.
The two PUC commissioners expect to issue a joint memo after the workshop. The memo will cover the consensus positions on a policy that could be addressed within the pilot. If so, it will most likely be addressed at the July 14 meeting.
PUC Task Forces & Target Implementation Date For The Pilot
McAdams proposed a task force that would discuss and observe the implementation of the pilot. It would also address operational obstacles and help to identify Commission policy areas that the PUC needs to make determinations. The task force plans to tackle issues that the PUC needs to give ERCOT instructions on.
McAdams said that a target implementation date or session for the pilot needed to be set. He added that the working group would be invitation-only. This is to ensure that number of participants will be manageable.

Tesla launches first Virtual Power Plant in UK – get paid to use solar
Tesla has launched its first-ever Virtual Power Plant program in the United Kingdom.
Tesla has launched its first-ever Virtual Power Plant program in the United Kingdom. This feature enables users of solar panels and energy storage systems to sell their excess energy back to the grid.
Tesla is utilizing Octopus Energy, a British renewable energy company that operates in multiple markets, including the UK, France, Germany, Italy, Spain, Australia, Japan, New Zealand, and the United States, as the provider for the VPP launch in the region.
The company states that those who enroll in the program can earn up to £300 per month.
Tesla has operated several VPP programs worldwide, most notably in California, Texas, Connecticut, and the U.S. territory of Puerto Rico. This is not the first time Tesla has operated a VPP outside the United States, as there are programs in Australia, Japan, and New Zealand.
This is its first in the UK:
Our first VPP in the UK
You can get paid to share your energy – store excess energy in your Powerwall & sell it back to the grid

Tesla is not the only company that is working with Octopus Energy in the UK for the VPP, as it joins SolarEdge, GivEnergy, and Enphase as other companies that utilize the Octopus platform for their project operations.
It has been six years since Tesla launched its first VPP, as it started its first in Australia back in 2019. In 2024, Tesla paid out over $10 million to those participating in the program.
Participating in the VPP program that Tesla offers not only provides enrolled individuals with the opportunity to earn money, but it also contributes to grid stabilization by supporting local energy grids.

Tesla Lathrop Megafactory celebrates massive Megapack battery milestone
The Tesla Megapack is the backbone of Tesla Energy’s battery deployments.
The Tesla Lathrop Megafactory recently achieved a new milestone. As per the official Tesla Megapack account on X, the Lathrop Megafactory has produced its 15,000th Megapack 2 XL battery.
15,000 Megapack Batteries
Tesla celebrated the milestone with a photo of the Lathrop Megafactory team posing with a freshly produced Megapack battery. To commemorate the event, the team held balloons that spelled out “15,000” as they posed for the photo.
The Tesla Megapack is the backbone of Tesla Energy’s battery deployments. Designed for grid-scale applications, each Megapack offers 3.9 MWh of energy and 1.9 MW of power. The battery is extremely scalable, making it perfect for massive energy storage projects.
More Megafactories
The Lathrop Megafactory is Tesla’s first dedicated facility for its flagship battery storage system. It currently stands as the largest utility-scale battery factory in North America. The facility is capable of producing 10,000 Megapack batteries every year, equal to 40 GWh of clean energy storage.
Thanks to the success of the Megapack, Tesla has expanded its energy business by building and launching the Shanghai Megafactory, which is also expected to produce 40 GWh of energy storage per year. The ramp of the Shanghai Megafactory is quite impressive, with Tesla noting in its Q1 2025 Update Letter that the Shanghai Megafactory managed to produce over 100 Megapack batteries in the first quarter alone.
Tesla Energy’s Potential
During the first quarter earnings call, CEO Elon Musk stated that the Megapack is extremely valuable to the energy industry.
“The Megapack enables utility companies to output far more total energy than would otherwise be the case… This is a massive unlock on total energy output of any given grid over the course of a year. And utility companies are beginning to realize this and are buying in our Megapacks at scale,” Musk said.

Tesla Megapacks powers the xAI Colossus supercomputer
Tesla Megapacks step in to stabilize xAI’s Colossus supercomputer, replacing natural gas turbines. Musk’s ventures keep intertwining.
Tesla Megapack batteries will power the xAI Colossus supercomputer in Memphis to ensure power stability. The collaboration between Tesla and xAI highlights the synergy among Elon Musk’s ventures.
The artificial intelligence startup has integrated Tesla Megapacks to manage outages and demand surges, bolstering the facility’s reliability. The Greater Memphis Chamber announced that Colossus, recently connected to a new 150-megawatt electric substation, is completing its first construction phase. This transition addresses criticism from environmental justice groups over the initial use of natural gas turbines.
“The temporary natural gas turbines that were being used to power the Phase I GPUs prior to grid connection are now being demobilized and will be removed from the site over the next two months.
“About half of the operating turbines will remain operating to power Phase II GPUs of xAI until a second substation (#22) already in construction is completed and connected to the electric grid, which is planned for the Fall of 2025, at which time the remaining turbines will be relegated to a backup power role,” the Chamber stated.
xAI’s rapid development of Colossus reflects its ambition to advance AI capabilities, but the project has faced scrutiny for environmental impacts. The shift to Megapacks and grid power aims to mitigate these concerns while ensuring operational continuity.
The Megapack deployment underscores the collaboration among Musk’s companies, including Tesla, SpaceX, Neuralink, and The Boring Company. Tesla appears to be the common link between all of Musk’s companies. For example, The Boring Company built a tunnel in Giga, Texas. In addition, Musk has hinted at a potential collaboration between the Tesla Optimus Bot and Neuralink. And from January 2024 to February 2025, xAI invested $230 million in Megapacks, per a Tesla filing.
Tesla Energy reported a 156% year-over-year increase in Q1 2025, deploying 10.4 GWh of storage products, including Megapacks and Powerwalls. Tesla’s plans for a new Megapack factory in Waller County, Texas, which is expected to create 1,500 jobs in the area, further signal its commitment to scaling energy solutions.
As xAI leverages Tesla’s Megapacks to power Colossus, the integration showcases Musk’s interconnected business ecosystem. The supercomputer’s enhanced stability positions xAI to drive AI innovation, while Tesla’s energy solutions gain prominence, setting the stage for broader technological and economic impacts.
