The overarching project objective is to develop and demonstrate a Distribution Management System (DMS) that aggregates distributed generation (DG), energy storage, and demand response technologies in a distribution system to achieve both distribution and transmission level benefits. Ideally, the application of these technologies would increase system reliability and improve power quality along with reducing costs to both the utility and its customers.

The advanced energy storage system is installed at the Maui Electric Company substation in Wailea as part of the Maui Smart Grid Project.

The Grid Storage Solution was provided by A123 Systems (NEC Energy Solutions), a developer and manufacturer of advanced lithium ion batteries and systems. It is designed to deliver one megawatt of power for a full hour, reducing the peak energy load on the substation’s transformers.
