Diesel & natural-gas gensets for sale
How much does a diesel generator cost?
Gensets are quoted per unit on request — the price depends on kW rating, frequency, emissions tier, enclosure, and hours. Tell us your load and we will return pricing and availability.
What generator do I need for a 2 MW datacenter block?
The Cummins QSK60 (~2000 kW) and QSK78 (~2400 kW) are common standardization points for 2 MW blocks; the QSK95 reaches 3000 kW for larger nodes. We will help match rating to your load.
Are the generators EPA emissions certified?
Yes — sets are offered in EPA Tier 2 and, where available, Tier 4 Final configurations. The certification of a specific unit is confirmed at quote.
What is the lead time on a standby generator?
In-stock sets ship far faster than a new OEM build. Exact lead time is confirmed per unit at quote.
