Tesla Inc. is reportedly ramping up its recruitment efforts at its Gigafactory 2 in Buffalo, NY, with the company set to hold five information sessions over the next month to seek out potential employees for the 1.2-million-square-foot facility.

Tesla’s recruitment initiatives were reported on local news agency The Buffalo News, which stated that the company is attempting to hire more workers amid Tesla’s production of its highly-anticipated Solar Roof tiles. The five information sessions are reportedly Tesla’s most extensive in-person hiring initiative for its energy branch since the company acquired SolarCity back in 2016.

A look at Tesla’s Careers page shows almost three dozen job openings for the Buffalo, NY facility. Among the open positions are posts for CAD/Revit modelers, environmental health and safety technicians, maintenance supervisors, and equipment maintenance technicians, to name a few. According to the publication, Tesla, just like its partner, Panasonic, would be offering a $14/hour pay for entry-level posts.

Tesla’s production jobs will reportedly be built around 12-hour shifts, with four shifts of workers working from Monday to Sunday. There will be two day shifts running from 7 a.m. to 7:30 p.m.; one running from Sunday to Tuesday and another running from Thursday to Saturday. The two night shifts for Gigafactory 2 are set to run from 7 p.m. to 7:30 a.m., and will follow the same system for the employees’ working days.

Tesla’s hiring ramp for the Buffalo, NY Gigafactory 2 comes at a time when customer installations of the company’s Solar Roof tiles appear to be starting. Just recently, we reported on what could very well be the first installation of Tesla Solar Roofs on a residential unit. The owner of the house, who goes by the handle @Toblerhaus on Twitter, shared photos of the 9.9 kW system. As noted by the Twitter user, the solar tiles were every bit as beautiful as her family had hoped.

As we noted in a previous report, Tesla had begun the production of Solar Roof tiles in Gigafactory 2 late last year. According to an email from the Elon Musk-led company, production of the solar shingles started in December, with the first customer installations expected to begin in the following months. Considering reports from customers like @Toblerhaus, it appears that Tesla’s target for the Solar Roof installations is within schedule.

Tesla’s Solar Roofs, together with the home Powerwall 2 battery unit, are part of the company’s goals of helping its customers achieve “sustainable energy independence,” as noted in a investor communication from Q2 2017. Initially manufactured in the Fremont factory, the solar shingles, which are designed to look identical to traditional roofing material, were eventually produced in the 1.2-million-square-foot Gigafactory 2 in Buffalo, NY. Production of the Solar Roofs was initially planned for the summer of 2017, though this date was eventually moved to 2018.

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.

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.

Tesla’s new Megablock system can power 400,000 homes in under a month

Tesla also unveiled the Megapack 3, the latest iteration of its flagship utility scale battery.

Tesla has unveiled the Megablock and Megapack 3, the latest additions to its industrial-scale battery storage solution lineup. 

The products highlight Tesla Energy’s growing role in the company, as well as the division’s growing efforts to provide sustainable energy solutions for industrial-scale applications.

Megablock targets speed and scale

During the “Las Megas” event in Las Vegas, Tesla launched Megablock, a pre-engineered medium-voltage block designed to integrate Megapack 3 units in a plug-and-play system. Capable of 20 MWh AC with a 25-year life cycle and more than 10,000 cycles, the Megablock could achieve 91% round-trip efficiency at medium voltage, inclusive of auxiliary loads.

Tesla emphasized that Megablock can be installed 23% faster with up to 40% lower construction costs. The platform eliminates above-ground cabling through a new flexible busbar assembly and delivers site-level density of 248 MWh per acre. With Megablock, Tesla is also aiming to commission 1 GWh in just 20 business days, or enough to power 400,000 homes in less than a month. 

“With Megablock, we are targeting to commission 1 GWh in 20 business days, which is the equivalent of bringing power to 400,000 homes in less than a month. It’s crazy. How are we planning to do that? Like most things at Tesla, we are ruthlessly attacking every opportunity to save our customers time, simplify the process, remove steps, (and) automate as much as we can,” the company said.

Megapack 3 is all about simplicity

The Megapack 3 is Tesla’s next-generation utility battery, designed with a simplified architecture that cuts 78% of connections compared to the previous version. Its thermal bay is drastically simplified, and it uses a Model Y heat pump on steroids. The battery weighs about 86,000 pounds and holds 5 MWh of usable AC energy. Tesla engineers incorporated a larger battery module and a new 2.8-liter LFP cell co-developed with the company’s cell team.

The Megapack 3 is designed for serviceability, and it features easier front access and no roof penetrations. About 75% of Megapack 3’s total mass is battery cells, with individual modules weighing as much as a Cybertruck. It’s also tough, with an ambient operating temperature range from -40C to 60C. This should allow the Megapack 3 to operate optimally from the coldest to the hottest regions on the planet.

Production is set to begin at Tesla’s Houston Megafactory in late 2026, with planned capacity of 50 GWh per year. Additional supply will come from Tesla’s 7 GWh LFP facility in Nevada, which is expected to open in 2025, as well as with third-party partners.

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.
