Generator test services are a great profit center for electrical contractors and generator service organizations. It is no secret that the demand for generator test services has been strong for many years. While the number of service providers has no doubt increased in response to the demand, there are still pockets of opportunity within this market.
Where are the opportunities?
Virtually all new generator installations require load testing before being placed into service. This has turned portable load banks into a great source of revenue in the generator service and equipment rental market. If you are in this field, but looking to differentiate from your competition, I would suggest that you look at the large load bank market, where competition remains fairly limited.
As engine manufacturers increase the power output of their engines, larger on-site power generators are finding their way into municipal facilities, hospitals, and large commercial complexes. Whether during initial commissioning, or during quarterly/yearly testing, large load banks are a necessity for these projects and, in certain areas, there are just not enough of them deployed in the field to meet the demand.
How large is “large”?
Here are two examples of Simplex load banks designed for testing of large generators:
