Reliable power isn’t proven during testing.
It’s proven when everything else fails.

Multi-family properties require a different approach to backup power. Instead of powering a single home, systems are designed to support shared infrastructure and essential building operations.
Typical systems prioritize:
• Common areas and lighting
• Elevators and access systems
• Mechanical systems and utilities
• Emergency and safety systems
Full-unit backup is less common, but targeted system design ensures continuity where it matters most.
Do generators power every unit in an apartment or condo building?
In most cases, no.
Typical systems are designed to support:
Common areas like hallways and lobbies
Elevators and access systems
Emergency lighting and safety systems
Core mechanical infrastructure
Full-unit backup requires significantly larger systems and is less common in standard multi-family properties.
What size generator does a multi-family property need?
Sizing depends on what the system is designed to support.
Typical ranges:
50–150kW supports essential building systems
150–300kW supports larger buildings with expanded systems
300kW+ supports high-rise or complex properties
Example:
A mid-size apartment building may use 100–200kW for core systems
Larger properties may require multiple generators
How long can a multi-family generator run during an outage?
Runtime depends on fuel type and system load.
Natural Gas
Continuous operation if supply is active
Diesel
A 150–250kW generator may use 10–20 gallons per hour• Tank size determines total runtime
Propane
Used in areas without gas access• Tank capacity determines duration
System design ensures the building can maintain critical operations for the required timeframe.

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.
