Choosing the right generator
Selecting a diesel generator comes down to power need, fuel efficiency and rental duration. Continuous jobs favor efficient mid-to-high kW units; short events may only need a compact size.
Frequently asked questions
- What size diesel generator do I need?
- Size to your total running load plus startup surge. 20 kW suits small needs, 56–100 kW fits mid-size job sites, and 200–320 kW covers large commercial projects. Use our sizing calculator or call us.
- Do you deliver and set up generators?
- Yes. We deliver, position and start up across the San Francisco Bay Area, and offer fuel delivery for long jobs.
- How much fuel does a diesel generator use?
- Consumption depends on load — a 100 kW unit may burn roughly 0.5–1 gallon per hour at partial load. See our fuel consumption rates by load.
- Are the generators single or three phase?
- All listed sizes are available in both single- and three-phase configurations.
