A few days ago, the Texas Public Utility Commission (PUC) said that it was creating a memo to address issues that Commissioner McAdams touched upon in the July 11 workshop. To recap, Tesla Energy has been working with the PUC and the Electric Reliability Council of Texas (ERCOT).

The focus is on educating the utility and the commission about the benefits of allowing Tesla Powerwall customers in Texas to participate in virtual power plants (VPPs).

Tesla’s U.S. Energy Markets Policy Lead, Arushi  Sharma Frank has been present at every meeting and has been working diligently to advocate for clean energy and Tesla Energy’s Texas customers.

The Memo

The previously mentioned future memo addresses some of the issues that Commissioner McAdams brought up in the July 11 workshop. He and Commissioner Glotfelty co-authored the memo.

The memo reads as follows:

As discussed during the June 16, 2022, Open Meeting and July 11, 2022, Aggregated Distributed Energy Resources (DER) Pilot Workshop, we support efforts to create a pilot project to test impacts of small-scale DER aggregation in the ERCOT market.

The pilot will answer questions related to how aggregated distributed generation can support reliability, enhance the wholesale market, incentivize investment, potentially reduce transmission and distribution investments, and support better load management during emergencies.

In the short term, we expect the pilot will bring in vital megawatts (MWs) of resources for participation in the ERCOT market.

ERCOT staff are required to prepare and present a governing document detailing the project scope to ERCOT’s board of directors.

The PUC will form a Task Force to identify operational obstacles to launching a pilot program and to assist ERCOT in drafting the governing document.

The next meeting to discuss the purpose and structure of the Task Force will be held on July 28, 2022. The governing document should be presented to the ERCOT board by October 11, 2022, so that it can meet a desired pilot start in the first quarter of 2023.

The Guiding Principles

The memo included five guiding principles that the commissioners want the pilot project to consider. They are:

  1. Understand the impact of having ancillary services carried on the distribution system.
  2. Create a structure that incentivizes competition and attracts broad DER participation through load-serving entities (LSEs).
  3. Measure the impacts of relieving or causing congestion on the distribution system, and study how to transition distribution-level aggregations to more granular dispatch and settlement.
  4. Ensure adequate customer protection is in place and information is anonymized.
  5. Start simple while ensuring economies of scale exist on a MW [megawatt]  basis to attract broad participation. The pilot parameters should have the flexibility to progress to more complex scenarios as participation increases.

 

 

Project Scope.

This next section of the memo addresses the governing document that shares the project scope with ERCOT’s board of directors. These topics are scale, duration, transmission and distribution utilities participation, interchange of customers, and reliability.

The following is from the memo detailing each topic:

Advertisement
  • Scale – Aggregations should be constrained within a load zone, with a single LSE, and served by the same transmission and distribution service provider (TDSP) with the potential for DER Management Systems (DERMS) aggregators to participate in the future. Participating TDSPs may limit pilot area based on feeder availability and information provided by LSEs related to their DER customers.
  • Duration – The pilot should continue until implementation of ERCOT market rules to accommodate aggregation or until ERCOT deems the pilot project unnecessary. We expect a minimum of 3 years which will allow for incorporation of EMS upgrades, testing of customer migration, and qualifying resources for ERCOT services.
  • TDSP Participation – It is imperative that competitive area transmission and distribution utilities (TDUs) and non-opt-in entities (NOIEs) participating in the pilot are willing participants and actively engaged to ensure safety and quality of experience to their customers. We expect reliability to be the ultimate consideration by TDSPs for qualifying DER customers.
  • Interchange of Customers – The acquisition of customers should be handled by the LSE with terms and conditions to provide relevant operational data and a good customer experience that prioritizes affordability and reliability.
  • Reliability – TDSPs should have the ability to manage participation considering system constraints, regular maintenance, and emergency situations. ERCOT in participation with the TDSPs shall be enabled to mitigate operational hazards and demands in this new era of transmission and distribution management.

Tesla VP hints at Solar Roof comeback with Giga New York push

The comments hint at possible renewed life for the Solar Roof program, which has seen years of slow growth since its 2016 unveiling.

Tesla’s long-awaited and way underrated Solar Roof may finally be getting its moment. During the company’s Q3 2025 earnings call, Vice President of Energy Engineering Michael Snyder revealed that production of a new residential solar panel has started at Tesla’s Buffalo, New York facility, with shipments to customers beginning in the first quarter of 2026. 

The comments hint at possible renewed life for the Solar Roof program, which has seen years of slow growth since its 2016 unveiling.

Tesla Energy’s strong demand

Responding to an investor question about Tesla’s energy backlog, Snyder said demand for Megapack and Powerwall continues to be “really strong” into next year. He also noted positive customer feedback for the company’s new Megablock product, which is expected to start shipping from Houston in 2026.

“We’re seeing remarkable growth in the demand for AI and data center applications as hyperscalers and utilities have seen the versatility of the Megapack product. It increases reliability and relieves grid constraints,” he said.

Snyder also highlighted a “surge in residential solar demand in the US,” attributing the spike to recent policy changes that incentivize home installations. Tesla expects this trend to continue into 2026, helped by the rollout of a new solar lease product that makes adoption more affordable for homeowners.

Possible Solar Roof revival?

Perhaps the most intriguing part of Snyder’s remarks, however, was Tesla’s move to begin production of its “residential solar panel” in Buffalo, New York. He described the new panels as having “industry-leading aesthetics” and shape performance, language Tesla has used to market its Solar Roof tiles in the past.

“We also began production of our Tesla residential solar panel in our Buffalo factory, and we will be shipping that to customers starting Q1. The panel has industry-leading aesthetics and shape performance and demonstrates our continued commitment to US manufacturing,” Snyder said during the Q3 2025 earnings call.

Snyder did not explicitly name the product, though his reference to aesthetics has fueled speculation that Tesla may finally be preparing a large-scale and serious rollout of its Solar Roof line.

Originally unveiled in 2016, the Solar Roof was intended to transform rooftops into clean energy generators without compromising on design. However, despite early enthusiasm, production and installation volumes have remained limited for years. In 2023, a report from Wood Mackenzie claimed that there were only 3,000 operational Solar Roof installations across the United States at the time, far below forecasts. In response, the official Tesla Energy account on X stated that the report was “incorrect by a large margin.”

Reports from China have indicated that the Tesla Shanghai Megafactory has become a notable player in China’s booming battery export market.

Located in the Lingang New Area of the Shanghai Free Trade Zone, the Tesla Megafactory has been running at full throttle since opening in February. It produces Tesla Megapack batteries for domestic and international use.

Tesla Shanghai Megafactory

As noted in a report from Sina Finance, the Tesla Shanghai Megafactory’s output of Megapack batteries helped drive a notable rise in lithium battery shipments from the city in the first three quarters of 2025. This is quite impressive as the Megafactory is a rather young facility, though it has been steadily increasing its production capacity.

“The establishment of this benchmark factory has not only driven the rapid development of Shanghai’s energy storage industry but also become a new growth engine for foreign trade exports. Driven by the Tesla energy storage factory’s opening, Shanghai’s lithium battery exports reached 32.15 billion yuan ($4.5 billion) in the first three quarters, a 20.7% increase,” the publication wrote.

Ultimately, the Shanghai Megafactory has proved helpful to the city’s “new three” industries, which are comprised of new energy vehicles, lithium batteries, and photovoltaic systems. Exports of the “new three” products reached 112.17 billion yuan ($15.7 billion), a 6.3% year-over-year increase during the same period. The city’s total trade volume grew 5.4% year-over-year as well, with exports up 11.3%, driven largely by the clean energy sector’s performance.

Energy storage is helping Shanghai

Since opening in February, the Shanghai Megafactory has been firing on all cylinders. In late July, Tesla Energy announced that the new battery factory has successfully produced its 1,000th Megapack unit. That’s quite impressive for a facility that, at the time, had only been operational for less than six months. 

Speed has always been a trademark of the Shanghai Megafactory. Similar to Tesla’s other key facilities in China, the Megafactory was constructed quickly. The facility started its construction on May 23, 2024. Less than a year later, the site officially started producing Megapack batteries. By late March 2025, Tesla China noted that it had shipped the first batch of Megapack batteries from the Shanghai plant to foreign markets.

Tesla will recall Powerwall 2 units in Australia after a handful of property owners reported fires that caused “minor property damage.” The fires were attributed to cells used by Tesla in the Powerwall 2.

Tesla Powerwall is a battery storage unit that retains energy from solar panels and is used by homeowners and businesses to maintain power in the event of an outage. It also helps alleviate the need to rely on the grid, which can help stabilize power locally.

Powerwall owners can also enroll in the Virtual Power Plant (VPP) program, which allows them to sell energy back to the grid, helping to reduce energy bills. Tesla revealed last year that over 100,000 Powerwalls were participating in the program.

Tesla announces 100k Powerwalls are participating in Virtual Power Plants

The Australia Competition and Consumer Commission said in a filing that it received several reports from owners of fires that led to minor damage. The Australian government agency did not disclose the number of units impacted by the recall.

The issue is related to the cells, which Tesla sources from a third-party company.

Anyone whose Powerwall 2 unit is impacted by the recall will be notified through the Tesla app, the company said.
