PROMIS™

(Portable RObust Microgrid Integrated Storage System)

A mobile battery energy storage system.

Overview

PROMIS is a portable energy storage system primarily designed for emergency energy supply to single- and three-phase customers. It is designed for frequent relocation and fast interconnection at a new site using a standard generator terminal box with Cam-lok™ plugs. PROMIS is a clean replacement for emergency (portable) diesel generators. Furthermore, it operates in grid-connected mode for grid support functions. The PROMIS™ platform is equipped with integrated microgrid technology and an on-board controller that provides comprehensive sets of autonomous controls, optimization schemes, and supervisory capability for ease of remote operator access and integration back to the Dispatch Center for overall grid coordination.

Replacement for Emergency Diesel Generators

Outage Management and Maintenance Support Replaces traditional forms of backup generation units (e.g., diesel generators) for supplying customers during service interruptions due to outage or maintenance. 

Peak Load and Demand Charge Management Provides peak-shaving capabilities during periods of high demand or high electricity prices to relieve loading on utility assets and achieve global cost reduction. 

Voltage Control Mitigates and improves commonly experienced voltage issues to enhance customers’ power quality on the distribution system through corrective actions.
