Overview

The GREEN GRID 90kilowatt-hour MBESS that outputs at 20 kVA continuous power. It’s the first UL9540 certified mobile solution, meeting the highest standards of safety, patent pending by Dominion Energy and built as a clean, scalable alternative to diesel.

 

It delivers both 120V and 208V three-phase power, with deployable rooftop solar panels, so it’s continuously recharging.


It can charge Electrical Vehicles and it can also recharge itself—whether from an EV charging station, the grid, or external PV inputs. And when needed, it can operate as a hybrid system, using a generator to recharge efficiently matching output to demand, running longer at low loads, reducing fuel consumption and operating costs. 



Emergency / Disaster Use Cases:

Back-Up Power for Shelters / Housing, Donation Centers, Medical Sites, Critical Businesses, Resiliency Hubs, Mobile Internet & 911 & 1st Responders.


Utility Use Cases:

EV Fleet Ops, ePTO Field Re-charge, Facilities Back-Up, Mobile Microgrid, Events, Festivals.

Community Resilience

The GreenGrid 90K MBESS is a 90 kWh/20 kVA trailer-mounted battery energy storage system

designed to deliver safe, silent and quickly deployable power for community resilience. This

guide translates technical capabilities into decision-grade deployment strategies, featuring

real-world case studies that demonstrate proven success across five critical use cases.

Utility Case Study & Use Case

The GreenGrid 90K MBESS is a trailer-mounted battery energy storage system with 90 kWh usable capacity and 20 kVA continuous three-phase output, delivering instant, clean backup power for critical facilities, microgrids, and remote sites—without the noise or emissions of traditional generators. Engineered for versatility, it supports five key applications: critical facility backup, planned outage support for utilities, disaster response and resilience hubs, temporary power for commissioning and construction, and emergency communications with EV charging. Proven in real-world deployments, the GreenGrid 90K has powered hospitals, shelters, construction sites, and disaster zones with reliable, emission-free energy.

Powering the Future of Construction

The GreenGrid 90K MBESS is a 90 kWh/20 kVA mobile battery energy storage system engineered to deliver silent, clean and compliant power at construction sites. Instead of relying on noisy diesel generators and complex fuel logistics, builders can deploy this trailer-mounted battery to energize switchgear, office trailers, cranes and electric equipment.
