High Power Grid Energy Storage

HR Energy Storage Technology

NEC Energy’s HR energy storage technology is a member of a family of products recognized as the industry’s most successful advanced grid energy storage solution. The HR (High Rate) delivers instant and accurate power for 15+ minutes. This high power capability combined with the the technology’s superior cycle life make it ideal for grid stability and renewable integration applications. This standard, configured-to-order and repeatable product provides high reliability, safety, and availability at an attractive total cost of ownership.

HR Key Benefits:

The HR energy storage technology is a low risk, high performing, and economic option for grid stability and renewable integration applications, with the following benefits:

Excellent Power Capacity Cost

  • Higher power with fewer batteries due to high power capability lowers capital expense
  • Standard, repeatable design reduces costs associated with custom built products
  • Superior cycle life lowers total cost of ownership (TCO) by reducing battery replacements even with high energy throughput applications

Low Project Risk

  • Over 100 MW of GSS® HR installations operating in commercial operations world wide
  • Low MTBF yields high system availability
  • Seamlessly boost energy capacity by adding incremental racks of energy storage at any point in project life
