Tesla’s Virtual Power Plant project in South Australia is only around ~2% complete, but it is already proving to be a difference-maker, rescuing Queensland’s grid during an unexpected power outage. The response time and efficiency of the Virtual Power Plant mirror that of Tesla’s other large-scale energy project in the region, the highly-acclaimed Hornsdale Power Reserve. 

Back in October, Queensland’s Kogan Creek coal power station, one of the largest in the region, tripped and caused the power system to drop well below the normal level of system frequency. Tesla’s Virtual Power Plant promptly stepped in, detecting the frequency drop and injecting power into the grid from Powerwall batteries loaded with energy from solar panels installed in SA Housing Trust properties across the state. 

In a statement about the VPP’s feat, South Australia Energy Minister Dan van Holst Pellekaan highlighted the fact that Tesla’s Virtual Power Plant is still in its early days. Despite this, it was able to respond quickly. The feat was no joke, considering that the Kogan Creek station is a fairly large coal power plant. “Although the Virtual Power Plant is in its early days, it is already demonstrating how it can provide the network support traditionally performed by large conventional generators,” he said

The Energy Minister’s statement is notable, considering that there are only about 900 homes forming the Virtual Power Plant as of date. Tesla’s target for the full VPP is a whopping 50,000 solar-powered, Powerwall-equipped homes. If less than 2% of the planned Virtual Power Plant can already rescue Queensland’s grid when a large coal plant fails, one can only imagine how much stability a fully-completed VPP could accomplish. 

Violette Mouchaileh, the executive general manager of emerging markets and services for the Australian Energy Market Operator (AEMO), expressed her optimism about the potential of Tesla’s Virtual Power Plant. “The SA VPP has proven the aggregation of distributed energy resources can benefit the power system and participating consumers. The opportunity for VPPs to reach a large scale will benefit all energy users through added competition to deliver services at reducing prices. We encourage more VPPS to register to accelerate the shared learning on how to safely and efficiently integrate, operate and regulate these emerging technologies into the NEM,” she said.

The buildout of Tesla’s Virtual Power Plant in South Australia is expected to be completed in three phases. In Phase 1, energy systems will be delivered to 100 SA Housing properties. Phase 2 increases this number with an additional 1,000 homes equipped with solar panels and Powerwall batteries. Phase 3, provided that it does push through, would expand the system to 50,000 homes. So far, Phase 1 has been completed, and Phase 2 appears to be nearing completion as well. 

Once complete, Tesla’s Virtual Power Plant in South Australia will deliver 250MW of solar energy and store 650 MWh of backup energy for the region. That’s notably larger than the Hornsdale Power Reserve, which is already changing South Australia’s energy landscape with its 100MW/129MWh capacity. In a way, Tesla’s Virtual Power Plant may prove to be a dark horse for the company’s Energy Business, which is unfortunately underestimated most of the time. Couple this with the 50% expansion of the Hornsdale Power Reserve, and Tesla Energy might very well be poised to surprise in the coming quarters.

Tesla Energy is the world’s top global battery storage system provider again

Tesla Energy captured 15% of the battery storage segment’s global market share in 2024.

Tesla Energy held its top position in the global battery energy storage system (BESS) integrator market for the second consecutive year, capturing 15% of global market share in 2024, as per Wood Mackenzie’s latest rankings.

Tesla Energy’s lead, however, is shrinking, as Chinese competitors like Sungrow are steadily increasing their global footprint, particularly in European markets.

Tesla Energy dominates in North America, but its lead is narrowing globally

Tesla Energy retained its leadership in the North American market with a commanding 39% share in 2024. Sungrow, though still ranked second in the region, saw its share drop from 17% to 10%. Powin took third place, even if the company itself filed for bankruptcy earlier this year, as noted in a Solar Power World report. 

On the global stage, Tesla Energy’s lead over Sungrow shrank from four points in 2023 to just one in 2024, indicating intensifying competition. Chinese firm CRRC came in third worldwide with an 8% share.

Wood Mackenzie ranked vendors based on MWh shipments with recognized revenue in 2024. According to analyst Kevin Shang, “Competition among established BESS integrators remains incredibly intense. Seven of the top 10 vendors last year struggled to expand their market share, remaining either unchanged or declining.”

Chinese integrators surge in Europe, falter in U.S.

China’s influence on the BESS market continues to grow, with seven of the global top 10 BESS integrators now headquartered in the country. Chinese companies saw a 67% year-over-year increase in European market share, and four of the top 10 BESS vendors in Europe are now based in China. In contrast, Chinese companies’ market share in North America dropped more than 30%, from 23% to 16% amid Tesla Energy’s momentum and the Trump administration’s policies.

Wood Mackenzie noted that success in the global BESS space will hinge on companies’ ability to adapt to divergent regulations and geopolitical headwinds. “The global BESS integrator landscape is becoming increasingly complex, with regional trade policies and geopolitical tensions reshaping competitive dynamics,” Shang noted, pointing to Tesla’s maintained lead and the rapid ascent of Chinese rivals as signs of a shifting industry balance.

“While Tesla maintains its global leadership, the rapid rise of Chinese integrators in Europe and their dominance in emerging markets like the Middle East signals a fundamental shift in the industry. Success will increasingly depend on companies’ ability to navigate diverse regulatory environments, adapt to local market requirements, and maintain competitive cost structures across multiple regions,” the analyst added.

Tesla inks multi-billion-dollar deal with LG Energy Solution to avoid tariff pressure

Tesla has reportedly secured a sizable partnership with LGES for LFP cells, and there’s an extra positive out of it.

Tesla has reportedly inked a multi-billion-dollar deal with LG Energy Solution in an effort to avoid tariff pressure and domesticate more of its supply chain.

Reuters is reporting that Tesla and LGES, a South Korean battery supplier of the automaker, signed a $4.3 billion deal for energy storage system batteries. The cells are going to be manufactured by LGES at its U.S. factory located in Michigan, the report indicates. The batteries will be the lithium iron phosphate, or LFP, chemistry.

Tesla delivers 384,000 vehicles in Q2 2025, deploys 9.6 GWh in energy storage

It is a move Tesla is making to avoid buying cells and parts from overseas as the Trump White House continues to use tariffs to prioritize domestic manufacturing.

LGES announced earlier today that it had signed a $4.3 billion contract to supply LFP cells over three years to a company, but it did not identify the customer, nor did the company state whether the batteries would be used in automotive or energy storage applications.

The deal is advantageous for both companies. Tesla is going to alleviate its reliance on battery cells that are built out of the country, so it’s going to be able to take some financial pressure off itself.

For LGES, the company has reported that it has experienced slowed demand for its cells in terms of automotive applications. It planned to offset this demand lag with more projects involving the cells in energy storage projects. This has been helped by the need for these systems at data centers used for AI.

During the Q1 Earnings Call, Tesla CFO Vaibhav Taneja confirmed that the company’s energy division had been impacted by the need to source cells from China-based suppliers. He went on to say that the company would work on “securing additional supply chain from non-China-based suppliers.”

It seems as if Tesla has managed to secure some of this needed domestic supply chain.

Tesla Energy has announced a fresh milestone for its newest Megapack factory. As per the electric vehicle maker, the Shanghai Megafactory has successfully produced its 1,000th Megapack battery. 

The facility was able to hit this milestone less than six months after it started producing the grid-scale battery system. 

New Tesla Megapack Milestone

As per Tesla Asia in a post on its official accounts on social media platform X, the 1,000th Megapack unit that was produced at the Shanghai Megafactory would be exported to Europe. As noted in a CNEV Post report, Tesla’s energy products are currently deployed in over 65 countries and regions globally. This allows Tesla Energy to compete in energy markets that are both emerging and mature.

To commemorate the 1,000th Megapack produced at the Shanghai Megafactory, the Tesla China team posted with the grid-scale battery with celebratory balloons that spelled “Megapack 1000.” The milestone was celebrated by Tesla enthusiasts on social media, especially since the Shanghai Megafactory only started its operations earlier this year.

Quick Megafactory Ramp

The Shanghai Megafactory, similar to Tesla’s other key facilities in China, was constructed quickly. The facility started its construction on May 23, 2024, and it was hailed as Tesla’s first entry storage project outside the United States. Less than a year later, on February 11, 2025, the Shanghai Megafactory officially started producing Megapack batteries. And by March 21, 2025, Tesla China noted that it had shipped the first batch of Megapack batteries from the Shanghai plant to foreign markets.

While the Shanghai Megafactory is still not at the same level of output as Tesla’s Lathrop Megafactory, which produces about 10,000 Megapacks per year, its ramp seems to be quite steady and quick. It would then not be surprising if Tesla China announces the Shanghai Megafactory’s 2,000th Megapack milestone in the coming months.
