About Us

Founded in 2002, Premium Power Corporation manufactures the world’s lowest cost, grid scalable flow batteries based on the company’s proprietary Zinc-Flow® advanced energy storage technology. Our products are lower in cost than lead acid batteries up front and roughly equivalent to pumped hydro, at under 2 cents/kWh, on a long-term basis. Our Company is headquartered in North Reading, Massachusetts, USA.

Our products offer a number of compelling advantages over alternative energy storage technologies. Primary benefits include:

• Lower initial cost and total cost of ownership;
• Longer operable life with an unlimited number of cycles;
• Fully integrated systems that can be trailer mounted to reduce installation and relocation time and cost;
• Greater energy density; and
• A wide degree of packaging flexibility.

• Utility infrastructure. Reserve power for electric utility facilities that provide transmission and distribution of electricity, providing benefits associated with:
  • Asset deferral;
  • Peak demand management;
  • Voltage support of long radial circuits;
  • Energy arbitrage; and
  • Ancillary services.
• Bulk energy storage for renewable energy generation assets including wind and solar, to provide:
  • Firming;
  • Smoothing;
  • Time shifting; and
  • A reduction in curtailment events.
• Peak-shaving (load shifting) to reduce end-users’ electricity costs by lowering peak demand and time-of-use energy charges.
• Electric power back-up of mission-critical equipment in locations such as wireless cell sites, POPs, central offices, cable communications head-ends, data centers, and utility substations.
