Utility Case Study

Mobile Substation

Problem

How do you ensure uninterrupted power supply during transmission and distribution line overhauls that have lengthy timelines?
How do you compensate inadequacy of substations for growing load demands?
How do you ensure backup supply in emergency conditions?

Solution

TROES’ Battery Energy Storage in conjunction with a mobile substation can provide uninterrupted power and compensate for capacity constraints of existing substations. The unit can be relocated to sites with power inadequacies and support seasonally peaking demands.

About The System

This Non-Wire Alternative System can be relocated between substations to reliably provide power, compensate for inadequate systems or provide backup in emergency conditions.

Our proprietary battery designs include a Battery Management System (BMS) with 3-layers of control and 3-layers of operation protection and an AI powered Dual-Equilibrium™ Technology, proven to improve battery lifecycle & overall system efficiency.
