Transforming Energy for America

 Battery Energy Storage System (BESS) is an electrochemical device that collects and stores energy from the electrical grid or a power plant, then discharges that energy later to provide electricity or other grid services when needed. The BESS market is rapidly growing and so is the need for reliable transformers to power them.

Virginia Transformer is the leader in supplying transformers to the BESS market. Our units are custom designed with a 60-year lifespan for the unique requirements of BESS projects, with special considerations for over-voltages, inverter applications, harmonics, saturation, and power factors. Robust engineering and quality control measures ensure each transformer is BAA compliant and built to the highest industry standards for superior reliability and performance.

With six manufacturing plants across North America and the shortest lead times in the industry, Virginia Transformer is the trusted supplier of power solutions for all BESS applications.


E2Vs flexible configuration enables users to build a scalable integrated power module that includes,

  • Low voltage distribution that can support DC Fast Chargers for your station configuration
  • Output power ranging from 500kVA to 4,000 kVA
  • AC Input Voltage ranging from 15 to 35 kV Class
  • All units have AC Output Voltage of 480V AC 3-phase at 60hZ
  • Additional step down available for Level 2


E2V innovative design takes away the logistical and installation complexities by providing a safe solution with medium voltage switchgear preventing fault from traveling upstream and a dry transformer that seamlessly steps down medium voltage to 480 volts then to low voltage distribution. So, no field integration is required.
