Diesel Generator Set RFQ: Scope, Options and Exclusions

How to frame a 90 kW prime / 100 kW standby, 60 Hz diesel generator RFQ so bidders price the same scope, options and exclusions.

Start by deciding which rating the RFQ is built around: 90 kW prime or 100 kW standby. The answer changes the alternator, cooling and fuel assumptions bidders make, so state the intended duty and require pricing against that rating only.

Then make the boundary of supply explicit. Ask each bidder to list what is included and excluded: fuel tank and piping, exhaust and silencing, foundation or skid, control panel and protection, cabling, commissioning and operator training. A simple table of include/exclude per line lets you compare offers without guessing.

Use the catalog values as reference points, not guarantees: 60 Hz, 1,800 rpm, 90 kW prime and 100 kW standby. Ask bidders to confirm the delivered set's rating basis and the conditions behind it. In a demonstration or acceptance test, agree in advance what will be checked, such as control functions and protection settings, and who witnesses it.

Before requesting a quote, confirm with the supplier the rating basis offered, the exact scope and exclusions, option pricing, and what documentation and test evidence will accompany delivery.
