Generators available: condition, price and delivery readiness
Buy generator sets by their actual fuel, electrical rating, frequency, voltage, condition and included scope. New, unused and used units are described separately in the current records. J&J is your generator supplier for the equipment purchase and agreed packaging scope; request a written quotation and technical package for the selected units.
For immediately available generators, review the 25 Jenbacher J420E 1.5 MW packages in the offered 50 Hz configuration. J&J does not convert these units. The CAT G3520K package has a separate equipment-readiness milestone within 90 days of deposit received in escrow. Other units have their own release schedule.
Ready to ship, ready to go, fast delivery and expedited delivery depend on the selected equipment, preparation, loading and route. For emergency replacement generators or a spare-engine requirement, send the existing nameplate, acceptable condition, needed-on-site date and required package interfaces. Rebuilt, reconditioned, secondhand and pre-owned requirements are reviewed against the documented condition of an actual offer.
Common questions
Written quotes and supporting records control unit-specific ratings, availability, condition, price, and delivery.
What is the used Cummins QSK60 G5 price and condition?
100 used units are offered at $575,000 USD per unit, shipping included. Each unit has over 7,500 operating hours. This is separate from the 25 brand-new Cummins units.
Will J&J convert the 50 Hz J420 units?
No. 25 J420E units are immediately available in their existing 50 Hz configuration. Any conversion must be engineered, arranged and paid for by the buyer; J&J will not convert the units.
What is the new Cummins QSK60 output at each frequency?
The supplied datasheet rates continuous output at 1,300 kW at 60 Hz and 1,120 kW at 50 Hz, approximately 1.1 MW. It specifies GQSK60-G5 at 50 Hz and GQSK60-G8 at 60 Hz; confirm the required configuration with the order.
Can J&J supply and package units for 250 MW or 500 MW generator requirements?
Yes. J&J has multiple generator allocations available and can supply and package units for these capacities. The advertised 250 MW and 500 MW offerings are natural gas. J&J can also supply diesel generator packages. The quotation confirms the actual generators, unit mix, fuel specification, frequency, condition, included equipment and release schedule. The two package sizes do not establish separate inventory totals.
