Generator rental is priced per day, per week or per month, and the longer you rent the lower the daily cost. A price list from a New York State contract shows that clearly for three common sizes. This page uses it, explains what is separate from the rental rate, and covers the grounding rules that apply to power on a construction site.
A public price list
New York State's statewide heavy equipment rental contract has a price list from one contractor, effective January 10, 2024. Rates are listed per day, per week and per month.1
| Generator size | Per day | Per week | Per month |
|---|---|---|---|
| 19 to 29 kVA | $275 | $549 | $1,636 |
| 30 to 39 kVA | $308 | $829 | $1,929 |
| 100 to 109 kVA | $461 | $1,027 | $2,675 |
The same list shows loading and unloading and a per mile transport charge in their own columns, separate from the rental rates. It is a government contract list from 2024 and one contractor, so treat it as an example of how the pricing is structured. These are public contract and bid prices, not Detritus prices. We do not publish our customer prices, and your price will depend on your site, dates and local providers.
Tell us what will run, for how long and where. We source generators or temporary service through local providers on one agreement.
Safety and rules
On construction sites, OSHA requires ground fault circuit interrupters on 120 volt, single phase, 15 and 20 ampere receptacle outlets that are not part of the permanent wiring, or an assured equipment grounding conductor program. That program needs a written description at the jobsite, a competent person, daily visual inspection and recorded testing.2 OSHA also requires temporary wiring to be removed immediately when construction is complete.3
Ask your provider whether the generator comes with GFCI protection and how cords and distribution are supplied, since those are separate from the rental rate. Our temporary power page has a calculator for running and starting watts.
Reading a quote
The rental rate is only part of the cost.
The longer term had the lower daily cost in the list. Say how long you need power so the quote uses the right term.
Transport, fuel, cables and distribution were not in the rental rate in the list. Ask for each.
Add up what runs at once and allow for motors, which need more power to start. Check each tool's nameplate.
Ask who provides GFCI protection and who inspects the equipment.
Common questions
A New York State contract price list from 2024 shows 275 to 461 dollars per day, 549 to 1,027 per week and 1,636 to 2,675 per month for three sizes between 19 and 109 kVA, with transport charged separately. Your price depends on size, duration and location.
The list we cite does not show fuel in the rental rate, so ask your provider. Fuel is often a separate line.
Add the running watts of everything that will run at the same time, and allow extra for motors. Check the nameplate on each tool, and ask your provider to confirm the size.
OSHA requires GFCI protection or an assured equipment grounding conductor program on 120 volt, 15 and 20 ampere construction site outlets.
No. They are public contract prices from one state list. We do not publish our customer prices.
Yes. We source local providers on one agreement. Call sales at (888) 588-2607.
Local providers do the work; we hold the contract, own the problems, and send one bill. If a delivery gets missed, we contact the provider the same business day.
