When Tesla unveiled its next-generation energy storage systems—Megapack 3 and the new Megablock—on September 15, 2025, it marked a pivotal moment in the evolution of utility-scale battery energy storage.
The top five global energy storage system integrators (AC side) in Q1 2025 were: Sungrow, Tesla, BYD Energy Storage, HyperStrong, and CRRC Zhuzhou Institute. The shipment performance of leading players indicates that dominance in a single market is no longer sufficient to secure.
The top five manufacturers, CATL, EVE Energy, Hithium, CALB, and BYD, dominate the market, with the top two holding nearly 55% combined share. In Edition #3 -2022, you can access the ranking of 70+ PV Module manufacturers, 30+ Inverter manufacturers & 40+ Energy Storage.
The top five suppliers were Sungrow, Tesla, BYD, CRRC Zhuzhou Institute, and HyperStrong. Sungrow is expected to dominate the full-year ranking, while Tesla and BYD will compete intensely for the second spot.
Built from galvanized or stainless steel materials, the cabinet achieves IP54 to IP65 ingress protection, effectively isolating internal power components from moisture, dust, and corrosion.
This project is a core component of Reliance Power's broader renewable energy strategy, which includes over 2. 5 gigawatts (GW) of solar power development and more than 2.
