Tesla’s latest referral program prize includes a Tesla Semi race competition
Tesla updated its acclaimed Referral Program today, revealing several new rewards and extending popular perks for new and existing customers. Among the most notable updates are an opportunity to race the Tesla Semi around the company’s test track, as well as the extension of Free Unlimited Supercharging and a possible VIP invitation to what could be the Model Y reveal event.
Unlike past Referral Programs, the updated list of perks includes a fun competition among existing Tesla owners. As noted in the description for Tesla’s latest promotion that will run between Feb 1 to April 30, 2018, the person who can get the most number of friends to sign up for Tesla’s newsletter would have the opportunity to race the Tesla Semi around the company’s test track.
According to Tesla, each weekly winner would be ranked according to their times on the course. The performance of each winner behind the wheel of the electric long-hauler would also be posted on the Tesla app’s leaderboards.
Considering the astounding performance of the Tesla Semi, this particular perk in the company’s updated Referral Program could very well prove to be its most popular yet. Powered by four Model 3-derived electric motors, the Tesla Semi is capable of accelerating from 0-60 mph in 5 seconds without a full load.
Such acceleration is comparable to performance cars like the 2016 Ford Mustang V6 and the 2017 Chevrolet Camaro V6 1LE. Unlike these muscle cars, however, the Tesla Semi is a Class 8 truck that’s capable of towing 80,000 lbs. The acceleration was recently seen on video, when a Tesla Semi was spotted speeding through an industrial park that’s located between Tesla’s headquarters in Palo Alto and the company’s factory in Fremont, California.
Apart from the fun Tesla Semi reward, the latest Referral Program also includes an update to the company’s Supercharging policy. Model S and Model X buyers that purchase a vehicle after using an existing owner’s referral code, before the April 30 deadline, will receive free and unlimited use of Tesla’s global Supercharging network. In addition, a $500 credit will be given to the first friend each owner refers through their referral code. The $500 credit could be applied towards service or accessories, notes Tesla.
Tesla owners who earn five qualified referrals also earn a VIP invitation to the Elon Musk-led electric car and energy firm’s next unveiling event. Considering that Tesla has already unveiled the Tesla Semi and the next-generation Roadster, there is a pretty good chance that the next event would focus on the Model Y, the highly-anticipated compact SUV that will be built on Model 3’s architecture.
Tesla’s solar customers are can also earn perks by referring solar installations, including a $400 cash or $750 credit for each installed referral, a well as a Founders Series Powerwall 2 home battery unit.
We’ve provided the complete details of Tesla’s latest Referral Program below.

Tesla recalls Powerwall 2 units in Australia

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.
Tesla announces 100k Powerwalls are participating in Virtual Power Plants
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 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.
