It appears that Tesla Energy and Pacific Gas and Electric Company’s 730 MWh battery installation at Moss Landing in Monterey, California, is progressing well. As noted in a recent update from PG&E, the first batch of Tesla Megapacks has been successfully installed, allowing the project to take a step towards its target of starting operations in the second quarter of 2021.

The massive 182.5MW/730MWh battery storage system was initially announced in July, with the groundbreaking ceremony being held on the latter part of the month. During the project’s announcement, it was revealed that the completed battery system will involve a whopping 256 Tesla Megapacks, making it one of the largest battery installations in the globe.

The massive battery is poised to be utilized to help meet peak energy demands in the area. Once operational, the Tesla Megapacks would be able to store excess solar and wind energy generated when demand is low. This energy could then be used as demand picks up, especially in times when solar and wind are not available. Ultimately, the battery system is expected to improve the reliability of the electric grid, while reducing the region’s reliance on fossil fuels at the same time.

Beyond their capability to store and release excess energy as needed by the grid, the Tesla Megapacks are also expected to provide about $100 million worth of savings to PG&E over the project’s expected 20-year lifespan. Interestingly enough, Tesla’s deal with PG&E also includes the possibility of the battery being expanded to as large as 1.1 GWh in the future. As noted by Tesla, such a scale would be enough to power every home in San Fransisco for 6 hours.

Fong Wan, senior vice president of Energy Policy and Procurement at PG&E, noted that battery storage systems play a key role in enhancing the electric grid. This is especially notable as batteries provide a cleaner, more reliable alternative to conventional energy solutions. “Battery energy storage plays an integral role in enhancing overall electric grid efficiency and reliability, integrating renewable resources while reducing reliance on fossil fuel generation,” Wan said.

Tesla Energy has a lot of potential, with Elon Musk noting that the company’s battery storage business could very well be larger than Tesla’s electric car division. This is due to a rather simple reason, with Musk stating that the utility sector is larger than the automotive segment. Fortunately for Tesla, the grid-scale energy sector is ripe for disruption, making products such as the Megapack and the company’s Autobidder software a likely success.

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 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.
