Portable Power: Here Are Three Towable Generator Solutions for Contractors on the Move

Regardless of the need, towable diesel generators are among the most prevalent solutions for jobsite power. This is due in part to the range of available sizes — from smaller 20-kW generators for building construction to 2-MW tractor trailers to support microgrids. When choosing a towable diesel generator, there are key factors to consider to determine the right size and to ensure safe operation.

Selecting the right size generator is critical — not only in terms of performance but also cost. A dealer or rental partner can help in selecting the proper size generator for the job, starting with a site survey or job walk of the construction project. The goal is to have a generator that provides enough power that it doesn’t become overloaded, which can lead to downtime and unnecessary costs for service or for returning the generator to a rental partner and having a new one delivered. Conversely, renting a larger generator than required to energize the site increases costs for rental fees.

Ultimately, it is not a one-size-fits-all situation, and it’s important to remember that the generator power that worked for a past project might not be the best option for a current one. If you’re wondering how best to select a towable generator, we recommend these stories:
