High Energy Grid Energy Storage

LD Energy Storage TechnologyContainers_NEC_txt

NEC Energy’s LD energy storage technology is a member of a family of products recognized as the industry’s most successful advanced grid energy storage solution. This Long Duration (LD) system delivers instant energy when you need it, where you need it. Offering one hour or more of energy ideal for peak load reduction, renewable firming, and T&D support and upgrade deferral applications, this standard, configured-to-order and repeatable product provides high reliability, safety, and availability at an attractive total cost of ownership.

LD Key Benefits

The LD energy storage technology is an energy dense, highly efficient, extremely reliable solution for long duration applications with the following benefits:

Easily Installed

  • High energy density enables customers to install more kWh of energy in less total area
  • Offered in 20 foot, 40 foot, and 53 foot standard containers
  • Can also be installed in custom enclosures that meet the needs of the project
  • Can be installed inside buildings
  • Zero emissions, low noise, and safety certifications (including CE marking) simplify permitting process

Efficient & Flexible Operation

  • Reduce operating costs with excellent round trip efficiency and low auxiliary losses
  • Maximize your investment by using 100% DOD without impacting battery life
  • Enable multiple revenue streams by operating in multiple applications with AEROS® controls
