Another massive energy storage project backed by Tesla’s Megapack grid-scale batteries will go online this year in Australia, as the first batch of the site’s final materials needed to connect the site to the grid have officially arrived on site.
The transformers required to energize a 600MW/1,600MWh Tesla Megapack facility in Plumpton, Victoria have officially arrived, as detailed in a press release from site operator Lumea on Sunday. The site is expected to become operational sometime this year, connecting to a first-of-its-kind underground substation, coming as the latest of a series of projects to be announced and go online across Australia in recent months.
Those at the so-called Melbourne Renewable Energy Hub (MREH) welcomed the hardware over the weekend with a ceremony including Victorian Minister for the State Electricity Commission Lily D’Ambrosio, as well as others from Lumea and site partner Equis. Tesla’s 444 Megapacks originally arrived at the facility last May, and the project is expected to offer electricity to roughly 200,000 homes during times of peak energy use.
“The Lumea team is excited and very proud to be working with our customers Equis and the SEC to help them realise this important project,” said Craig Stallan, Lumea Executive General Manager. “The accelerated development of the MREH plays a key role in meeting Victoria’s ambitious timeline of renewable energy and net zero targets. We are working to safely connect this enormous battery to the grid, improving system strength and enabling access to renewable, affordable and reliable energy for consumers.”
The transformers were installed by a specialized Lumea crew, who used a “jack and skate” procedure to lift the two 335-tonne units onto their foundations. Lumea also says that a third transformer will arrive in February, all three of which will be used to convert and stabilize energy generated and stored at the facility.

“We’re excited to see the SEC’s first project take shape and continue to achieve construction milestones ahead of being operational later this year,” said David Moo, the State Energy Commission’s (SEC’s) General Manager of Asset Delivery. “The transformers being installed will enable the Melbourne Renewable Energy Hub to deliver up to 1.6 gigawatt hours of energy storage onto the grid – enough to power 200,000 homes during peak periods.”
Work will continue on the initial two transformers to get the site connected up through the arrival and installation of the third. The Megapack project will also connect to the grid through the existing Sydenham Terminal Station using a 1.75km, 500kV underground cable, and a 500kV Plumpton Renewable Terminal Substation, which Lumea says is the first such system of its kind in Australia.
“We are proud we have worked at pace with our partners to bring a critical Victorian energy project online,” said David Russell, Equis Managing Director. “With the SEC’s assistance the Melbourne Renewable Energy Hub is on track to complete within both the cost budget and time period forecasted.”

Tesla Cybercab coming next to Giga Berlin, Optimus possibly after
“From a next major product standpoint, I think most likely is the Tesla Cybercab,” Musk said.
Tesla could add the Cybercab and Optimus humanoid robot to the production lineup at Giga Berlin, as per recent comments from CEO Elon Musk.
During a recent interview with Giga Berlin plant manager André Thierig, Musk identified the Cybercab as the most likely next major product for the German factory, with Optimus potentially following after.
“From a next major product standpoint, I think most likely is the Tesla Cybercab,” Musk said. He added that there are also “possibilities of Tesla Optimus” being produced in the facility.
Tesla has already begun production of the Cybercab in Giga Texas, with volume production expected to ramp this year. Based on Musk’s comments, it appears that if conditions align in Europe, Giga Berlin could eventually join that effort.
The CEO’s comments about Optimus coming to Gigafactory Berlin are quite unsurprising too considering that Musk has mentioned in the past that the humanoid robot will likely be Tesla’s highest volume product in the long run.
Giga Berlin will likely be able to produce mass volumes of Optimus, as the Model S and Model X lines being converted to an Optimus line in the Fremont Factory are already expected to produce 1 million units of the humanoid robot annually.
Apart from his comments about the Cybercab and Optimus, Elon Musk also confirmed that Giga Berlin has started ramping battery cell production and will continue expanding Model Y output, particularly as supervised Full Self-Driving (FSD) gains regulatory approvals in Europe.
Taken together, the remarks suggest Berlin’s role could evolve beyond vehicle assembly into a broader multi-product manufacturing hub, not just a regional Model Y plant.

Tesla Powerwall distribution expands in Australia
Inventory is expected to arrive in late February and official sales are expected to start mid-March 2026.
Supply Partners Group has secured a distribution agreement for the Tesla Powerwall in Australia, with inventory expected to arrive in late February and official sales beginning in mid-March 2026.
Under the new agreement, Supply Partners will distribute Tesla Powerwall units and related accessories across its national footprint, as noted in an ecogeneration report. The company said the addition strengthens its position as a distributor focused on premium, established brands.
“We are proud to officially welcome Tesla Powerwall into the Supply Partners portfolio,” Lliam Ricketts, Co-Founder and Director of Innovation at Supply Partners Group, stated.
“Tesla sets a high bar, and we’ve worked hard to earn the opportunity to represent a brand that customers actively ask for. This partnership reflects the strength of our logistics, technical services and customer experience, and it’s a win for installers who want premium options they can trust.”
Supply Partners noted that initial Tesla Powerwall stock will be warehoused locally before full commercial rollout in March. The distributor stated that the timing aligns with renewed growth momentum for the Powerwall, supported by competitive installer pricing, consumer rebates, and continued product and software updates.
“Powerwall is already a category-defining product, and what’s ahead makes it even more compelling,” Ricketts stated. “As pricing sharpens and capability expands, we see a clear runway for installers to confidently spec Powerwall for premium residential installs, backed by Supply Partners’ national distribution footprint and service model.”
Supply Partners noted that a joint go-to-market launch is planned, including Tesla-led training for its sales and technical teams to support installers during the home battery system’s domestic rollout.

Tesla Giga Berlin growth could stall if not “free from external influences”: Elon Musk
The comments were delivered in a pre-recorded video discussion.
Tesla CEO Elon Musk has reportedly warned that future expansion of Gigafactory Berlin could be jeopardized if the site does not remain “free from external influences.”
Musk’s comments were delivered in a pre-recorded video discussion with employees and came at a sensitive moment for the facility, where union representation has been a recurring issue.
According to reports from Handelsblatt and Der Spiegel, citing participants at the event, Musk suggested that if Giga Berlin is no longer “free from external influences,” further expansion would become unlikely. He did not, however, hint that the plant would shut down.
While Musk did not name IG Metall directly, his remarks were widely interpreted as referencing the union, which is currently the largest faction on the works council but does not hold a majority, as noted in an electrive report.
The video conversation was conducted between Musk in Austin and Grünheide plant manager André Thierig, then played back to the workforce in Germany. Works council elections are scheduled for early March, heightening the tension between management and organized labor.
The CEO has previously voiced concerns that stronger union influence could limit Tesla’s operational flexibility and long-term strategy in Germany.
Despite the warning on expansion, Musk praised the Giga Berlin site during the same address, describing it as one of the most advanced factories worldwide and highlighting its cleanliness and team culture.
The discussion also reportedly touched on battery cell production. According to attendees cited in German media, Musk indicated that Tesla has begun ramping cell production at the site. That would mark a notable shift from earlier expectations that large-scale cell manufacturing in Brandenburg would not begin until 2027.
