Tesla’s grid-scale Megapack batteries have been selected for yet another battery energy storage system (BESS) in Europe, which is set to become one of the biggest projects of its kind on the continent.
On Tuesday, European energy provider Return detailed plans for the next phase of Project Mufasa, a 350MW/1.4GWh Tesla Megapack facility in Vlissingen, Netherlands, as announced in a press release. The site is being developed by the company’s Lion Storage brand and is expected to become operational by 2027, featuring 372 of Tesla’s four-hour 2XL Megapacks and becoming the largest BESS in the Netherlands and one of the largest across Europe.
Return will oversee construction of the site and it will also utilize a former coal-fired power plant in its connection to the electrical grid. The company also says that the amount of power will be sufficient to power over 200,000 households in the Vlissingen area, with the ability to discharge several times per day.
“Project Mufasa is a game-changer for battery storage in the Netherlands,” said Arno Hendriks, Lion Storage Co-Founder. “As the first of its kind to secure full project financing, it proves that energy storage is not just viable—it’s investable.”
The project is valued at over 350 million euros (~$365.6 million), and funding is being backed by Macquarie Capital as the lead equity investor, along with TINC, existing Return investors, and six other banks. Project Mufasa leaders are also partnering with Eneco, which will use revenue index models to help oversee and optimize day-to-day operations at the facility.
“With cutting-edge technology and strong strategic partnerships, we’re driving a smarter, more resilient energy future and setting the bar for what’s next in Europe,” said Jeroen Althoff, fellow Lion Storage Co-Founder.

“At Return, we’re not just building energy storage—we’re shaping the backbone of a cleaner, more resilient power system for Europe,” writes Willem-Jan Schutte, Return’s CEO. “The demand for reliable, large-scale storage has never been greater, and we’re ready to deliver. For those looking to be part of the energy transition—whether as partners, customers, or investors—Return is where innovation meets impact.”
Tesla has deployed or been involved in announcements relating to several BESS projects in the past several months, with recent projects becoming operational in Austria, Puerto Rico, and Texas, to name just a few. Earlier this month, the company also began production at its second Megapack factory, located in Shanghai, China, after spending the last few years ramping production at its Lathrop, California manufacturing facility.

Tesla Model Y and Model 3 named safest vehicles tested by ANCAP in 2025
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025.
The Tesla Model Y recorded the highest overall safety score of any vehicle tested by ANCAP in 2025. The Tesla Model 3 also delivered strong results, reinforcing the automaker’s safety leadership in Australia and New Zealand.
According to ANCAP in a press release, the Tesla Model Y achieved the highest overall weighted score of any vehicle assessed in 2025. ANCAP’s 2025 tests evaluated vehicles across four key pillars: Adult Occupant Protection, Child Occupant Protection, Vulnerable Road User Protection, and Safety Assist technologies.
The Model Y posted consistently strong results in all four categories, distinguishing itself through a system-based safety approach that combines structural crash protection with advanced driver-assistance features such as autonomous emergency braking, lane support, and driver monitoring.

This marked the second time the Model Y has topped ANCAP’s annual safety rankings. The Model Y’s previous version was also ANCAP’s top performer in 2022.
The Tesla Model 3 also delivered a strong performance in ANCAP’s 2025 tests, contributing to Tesla’s broader safety presence across segments. Similar to the Model Y, the Model 3 also earned impressive scores across the ANCAP’s four pillars. This made the vehicle the top performer in the Medium Car category.
ANCAP Chief Executive Officer Carla Hoorweg stated that the results highlight a growing industry shift toward integrated safety design, with improvements in technologies such as autonomous emergency braking and lane support translating into meaningful real-world protection.
“ANCAP’s testing continues to reinforce a clear message: the safest vehicles are those designed with safety as a system, not a checklist. The top performers this year delivered consistent results across physical crash protection, crash avoidance and vulnerable road user safety, rather than relying on strength in a single area.
“We are also seeing increasing alignment between ANCAP’s test requirements and the safety technologies that genuinely matter on Australian and New Zealand roads. Improvements in autonomous emergency braking, lane support, and driver monitoring systems are translating into more robust protection,” Hoorweg said.

Tesla Sweden uses Megapack battery to bypass unions’ Supercharger blockade
Just before Christmas, Tesla went live with a new charging station in Arlandastad, outside Stockholm, by powering it with a Tesla Megapack battery.
Tesla Sweden has successfully launched a new Supercharger station despite an ongoing blockade by Swedish unions, using on-site Megapack batteries instead of traditional grid connections. The workaround has allowed the Supercharger to operate without direct access to Sweden’s electricity network, which has been effectively frozen by labor action.
Tesla has experienced notable challenges connecting its new charging stations to Sweden’s power grid due to industrial action led by Seko, a major Swedish trade union, which has blocked all new electrical connections for new Superchargers. On paper, this made the opening of new Supercharger sites almost impossible.
Despite the blockade, Tesla has continued to bring stations online. In Malmö and Södertälje, new Supercharger locations opened after grid operators E.ON and Telge Nät activated the sites. The operators later stated that the connections had been made in error.
More recently, however, Tesla adopted a different strategy altogether. Just before Christmas, Tesla went live with a new charging station in Arlandastad, outside Stockholm, by powering it with a Tesla Megapack battery, as noted in a Dagens Arbete (DA) report.
Because the Supercharger station does not rely on a permanent grid connection, Tesla was able to bypass the blocked application process, as noted by Swedish car journalist and YouTuber Peter Esse. He noted that the Arlandastad Supercharger is likely dependent on nearby companies to recharge the batteries, likely through private arrangements.
Eight new charging stalls have been launched in the Arlandastad site so far, which is a fraction of the originally planned 40 chargers for the location. Still, the fact that Tesla Sweden was able to work around the unions’ efforts once more is impressive, especially since Superchargers are used even by non-Tesla EVs.
Esse noted that Tesla’s Megapack workaround is not as easily replicated in other locations. Arlandastad is unique because neighboring operators already have access to grid power, making it possible for Tesla to source electricity indirectly. Still, Esse noted that the unions’ blockades have not affected sales as much.
“Many want Tesla to lose sales due to the union blockades. But you have to remember that sales are falling from 2024, when Tesla sold a record number of cars in Sweden. That year, the unions also had blockades against Tesla. So for Tesla as a charging operator, it is devastating. But for Tesla as a car company, it does not matter in terms of sales volumes. People charge their cars where there is an opportunity, usually at home,” Esse noted.
