Generators are hired by kilowatt, on a ladder that runs from a $60 a day portable to a trailer mounted set at several hundred. The 20 kW towable, the common site and outage size, sits around $150 to $250 a day. The rate covers the set alone: cable, distribution and connection are yours to arrange.
The size ladder yards actually stock
Portable petrol units near 5 to 9 kW run hand tools and a site office. Towable diesel sets at 20 to 60 kW carry a small site or a house through an outage. Above that, machines from 100 kW upward arrive on a trailer for events and building loads, and are quoted by the week more often than the day.
Two smaller sets often beat one large one
Hiring generators in pairs lets you shut one down when the load drops overnight, keeps fuel burn honest and leaves you running when one fails. It also splits the machines between areas so cable runs stay short. The trade is two transport charges and two refuels, so it pays on longer jobs.
Cable and distribution are not in the rate
A set arrives with output terminals or sockets, not with anything to reach your work. Spider boxes, distribution panels and correctly rated flexible cable hire from the same counter and are quoted separately. Undersized, damaged or improvised cable is where most temporary power problems on a site begin.
Noise, siting and the neighbours
Site sets are enclosed and quoted with a sound rating, and a residential street or a hospital car park needs the quiet unit rather than whatever is nearest the gate. Position it away from openings and downwind, since exhaust drifts. Anything running overnight in a built up area is worth checking against the local ordinance.
Questions people ask about generator for rent
What size generator covers a house in an outage?
A set in the 15 to 25 kW range covers most homes where the well pump, the furnace and the fridge are the priority, and the figure climbs once central air joins the list. Total the running loads, then tell the yard which motors start at the same moment.
Is fuel included in a generator rental?
No. The set arrives full and either returns full or is refilled at the yard's rate, which sits above the pump price. On anything running more than a day or two, a fuel delivery to site is normally cheaper and saves somebody driving around with cans.
Can I rent a generator just for a weekend?
Yes, and small portables are the easiest thing on the shelf to get at short notice, with Saturday to Monday often priced as a single day. Larger towable sets need the hitch and trailer lights checked, so those are usually delivered instead.
