When it comes to industrial power generation, few purchasing decisions have a greater impact on long-term operating costs than choosing between a new and used generator. While new equipment offers the latest technology and manufacturer warranties, used units can provide substantial savings without sacrificing reliability, if you know what to look for.
The challenge is determining which option delivers the best value for your specific operation. Whether you’re powering a construction project, oilfield site, industrial facility, or backup power system, understanding the advantages and tradeoffs of each approach can help you maximize performance while protecting your budget.
At NexSource Power, we’ve worked with clients across Western Canada since 2009, helping them source, service, and deploy everything from used diesel generators to large-scale industrial natural gas generator systems. The right choice is rarely about simply buying the cheapest unit. It’s about understanding lifecycle costs, maintenance requirements, and operational goals.
Here’s what you should know before making your investment.
Why This Decision Matters More Than Most Buyers Realize
Industrial generators represent a significant capital investment. The purchase price is only one part of the equation.
Fuel consumption, maintenance expenses, equipment lifespan, resale value, and downtime risk all contribute to the total cost of ownership.
According to the U.S. Department of Energy, energy-efficient equipment and proper asset management can significantly reduce lifecycle operating costs for industrial facilities. Choosing the right equipment from the start often has a greater financial impact than short-term cost savings alone.
Likewise, the Electrical Generating Systems Association (EGSA) notes that preventive maintenance and proper equipment selection are among the most important factors affecting generator reliability and long-term performance.
For many organizations, the question isn’t simply whether to buy new or used. It’s the option that provides the strongest return on investment over the life of the asset.

The Downside of Buying New
While new equipment offers clear advantages, buyers should consider two important factors:
- Higher Capital Costs: A new natural gas industrial generator can require a significantly larger upfront investment than a comparable refurbished unit.
- Faster Depreciation: Like most industrial assets, generators experience their highest depreciation during the first few years of ownership.
Many buyers absorb this value loss despite operating the equipment for only a fraction of its total lifespan.
Why Used Generators Continue to Grow in Popularity
The industrial equipment market has evolved considerably over the past decade.
Today, professionally refurbished and load-bank-tested generators offer a practical alternative to purchasing new equipment.
Many organizations choose used natural gas generators or used diesel generators because they provide immediate cost savings while maintaining dependable performance.
Lower Acquisition Costs
Purchasing a used generator can reduce capital expenditures dramatically.
This helps organizations allocate funds toward:
