Tesla’s growth engine isn’t currently from EVs
Earlier this week, Tesla held an event in Las Vegas to introduce new products from its energy storage business, and it included a bit of a surprise. Its next-generation Megapack 3 energy storage system was introduced as expected. But the company also unveiled the new Megablock.
The Megablock combines several Megapacks along with electrical power system components. It’s a pre-engineered system that Tesla says will lower costs and installation times for large-scale energy projects. Mike Snyder, Tesla’s VP of energy and charging, also said that Tesla plans to build Megapack 3 in Houston starting late next year.
Tesla’s energy storage business is thriving even as its electric vehicle (EV) sales are slumping. Energy generation and storage revenue jumped 18% year over year to $5.5 billion in the first half of 2025. At the same time, automotive revenue declined by 18%.
Tesla shares have rallied 15% over the last month. Much of that happened this week after the Las Vegas presentation, which was also streamed live on Tesla’s X social media account. Investors had mostly been focusing on the potential of Tesla’s robotaxi when it is launched in volume.
In the meantime, the energy business is growing into a more meaningful part of Tesla’s revenue stream. That’s enough to move the stock much higher this week.
