Tesla’s Megapacks are set to support France’s largest battery energy storage system (BESS), on which the company has begun construction, as announced this week.
Harmony Energy has begun construction on the Cheviré 100 MW/200 MWh Megapack battery project in Nantes Saint-Nazaire Harbour, France, as detailed in a press release shared on Thursday. The battery project is made up of Tesla’s 2-hour Megapacks, and it will be expected to be able to provide enough electricity to power more than 170,000 homes for two hours.
Harmony is aiming to have the project completed and connected to the electrical grid next summer, with the system expected to become fully operational by the end of 2025.
Tesla Energy posts record 9.4 GWh of battery storage deployed in Q2 2024
“Developing and operating vital battery energy storage facilities across France, will lead to enhanced energy security, more affordable energy bills, and the decarbonisation of the grid,” wrote Andy Symonds, Harmony Energy CEO for the French market. “We are excited to commence building works on our first project.”
The Cheviré site was formerly home to a coal, gas, and oil power station, which was operational between 1954 to 1986. The release also highlights Tesla’s Autobidder system, a real-time trading platform made by the company that’s intended to help maximize operator revenue over time.
“It’s an exciting location given the historical importance of the fossil-fuel coal power station, but looking ahead, the delivery of the Cheviré BESS will transform the site into exactly the opposite, facilitating the green electrification of the French energy system, whilst offsetting several hundred thousand tons of CO2,” writes Clément Girard, Harmony Energy COO for France.
Tesla has several ongoing Megapack projects both in operation and under construction. The company recently highlighted another BESS project in California sporting 200 MW/800 MWh of Megapacks, and being built out of a former steam plant that was in operation until 2001.
On Thursday, Tesla announced a massive 15.3 GWh contract with Intersect Power to expand the companies’ current partnership of just 2.4 GWh. The updated commitment is expected to go from concept to commissioned in just a year, and it will include 966 MWh projects across three different sites in Texas.
Tesla currently builds the Megapack at a “Megafactory” in Lathrop, California, and the company is currently ramping up production at the facility. The company has also begun construction on a Megafactory in Shanghai, China, and it’s aiming to produce roughly 10,000 Megapacks per year at each facility upon reaching volume production.

Elon Musk estimates Tesla Semi could reach Europe next year
“We’ve got the Tesla Semi coming out, the heavy truck, and that’ll be going to Europe hopefully next year,” Musk said.
Tesla is preparing to expand its all-electric Semi truck program to Europe, with CEO Elon Musk indicating that the Class 8 vehicle could arrive in the region 2027.
Musk shared his update during an interview about Giga Berlin with plant manager André Thierig, which was posted on X by the official Tesla Manufacturing account.
“We’ve got the Tesla Semi coming out, the heavy truck, and that’ll be going to Europe hopefully next year,” he said.
Tesla has already begun limited production and customer deployments of the Tesla Semi in the United States, with the company working to scale output through the Semi factory near Giga Nevada. Considering Musk’s comments, it appears that a European rollout would be the next phase of the vehicle’s expansion beyond North America.
Musk’s use of the word “hopefully” leaves room for flexibility, but the remark signals that Europe is next in Tesla’s commercial expansion plans.
Musk has consistently argued that electrification should extend beyond passenger vehicles. During the same interview, he reiterated his view that “all ground transport should be electric,” adding that ships, and eventually aircraft, would follow.
The Semi plays a central role in that strategy. Heavy-duty freight remains one of the most emissions-intensive segments of road transport, and European regulators have increasingly pushed for lower-emission commercial fleets.
Tesla recently refreshed the Semi lineup on its official website, listing two variants: Standard and Long Range. The Standard trim offers up to 325 miles of range with an energy consumption rating of 1.7 kWh per mile, while the Long Range version provides up to 500 miles, which should be more than ample for European routes.

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.
