Overview
Retail environments rely on continuous operation to maintain sales, customer experience, and operational flow. Even short outages can result in lost transactions, spoiled inventory, and disruption to store operations.
Backup power systems for retail are typically designed to support point-of-sale systems, lighting, refrigeration where applicable, security systems, and select HVAC. Larger retail environments such as grocery stores or shopping centers may require higher-capacity systems or multiple generators to maintain performance across multiple spaces.
System design focuses on maintaining revenue continuity while balancing load requirements and operational priorities.
FAQs
What size generator does a retail store or shopping center need?
Sizing depends on the type of retail environment and what needs to remain operational.
Typical ranges:
Small retail stores often require 20–75kW to support lighting, POS systems, and basic operations.
Mid-size stores or restaurants typically require 75–150kW to support refrigeration, kitchen equipment, and HVAC.
Large retail spaces such as grocery stores or multi-tenant centers often require 150–400kW or more depending on load.
Example:
A clothing store may only need enough power for lighting and checkout systems.
A grocery store must support refrigeration, which significantly increases load requirements and drives system size.
The key difference is whether the system is designed for basic operation or full revenue continuity.
What systems should stay powered during an outage in a retail environment?
This depends on the type of business and how revenue is generated.
Most retail systems prioritize:
Point-of-sale systems so transactions can continue.
Lighting for customer safety and visibility.
Security systems including cameras and alarms.Refrigeration or cold storage for grocery and food-based retail.
Limited HVAC to maintain a usable environment.
Example:
A boutique may prioritize lighting and checkout systems.
A grocery store must prioritize refrigeration to prevent inventory loss and maintain compliance.
System design ensures the most important functions stay online first.
How long can a retail generator run during an outage?
Runtime depends on fuel type and system load.
Typical scenarios:
Natural gas systems can operate continuously if supply remains active.
Diesel systems may run for multiple days depending on tank size and demand.
Example:
A 150kW generator may consume 10–15 gallons per hour under load.
A 1,000-gallon diesel tank could support several days of operation depending on usage.
For retail, runtime planning is often tied to protecting inventory and maintaining revenue during extended outages.

Right-Sized Power Starts Here
From essential backup to full-scale operations—get a clear, grounded recommendation based on how your property actually runs.
Start With How
It Actually Runs
Not square footage. Not a guess.
We start at the end — how your property operates when it matters.What needs to stay on, what can’t go down, and what failure costs you.
1
Build the
Real Load Profile
This is where most systems go wrong.
We map real demand — startup loads, critical systems, usage patterns — so you’re not undersized when it counts or overbuilt.
2
Match the Right
System (Not Just a Size)
There isn’t “one generator.”
Fuel type, environment, runtime expectations, redundancy —we align the system to how it will be used, not just what it powers.
3
Install It So It Performs When It’s Needed
A system is only as good as how it’s deployed and maintained.
We handle installation, testing, and long-term support —so when the moment comes, it works as expected.
