What you are actually buying

A diesel generating set is bought as a package rather than a machine: engine and alternator, controller, acoustic enclosure, base fuel tank, changeover or automatic mains failure panel, cabling, foundation, exhaust routing and the statutory clearances that go with fuel storage and stack height. Bids differ on whether the rating quoted is standby or prime, on whether derating for site ambient temperature and altitude has been applied, on engine and alternator make, on enclosure sound level and the distance at which it is measured, and on how much of the civil, cabling and panel work sits inside the price. The usual mistake is sizing against connected load instead of the essential load actually to be backed, producing a set that runs lightly loaded, wet stacks and ages badly.

Why dg set suits collective purchasing

The correspondence puts DG sets among the top five categories for aggregation, and the structure supports it. Ratings come in a short ladder of standard sizes, so institutions buying different capacities are still buying from one catalogue and one specification. Manufacturers compete openly and each campus buys a single set, perhaps twice in a generation, which is precisely the fragmentation that pooling corrects. The set and the service contract pool well. The foundation, cabling, exhaust routing and local clearances do not, and should be priced as a separate local scope so the aggregated comparison is not distorted by site work.

Pin down before price

  • Rating declared as standby or prime kVA at site conditions, showing the derating applied for ambient temperature and altitude
  • Emission-norm compliance and the exact engine and alternator make and model, frozen before pricing
  • Enclosure sound level with the measurement distance stated, plus exhaust height and routing
  • Scope boundary in writing: changeover or AMF panel, cabling, earthing, foundation, fuel tank capacity and first fill
  • On-load site test against the actual essential load as a condition of acceptance

What drives ten-year cost

  • Fuel dominates the lifetime cost; specific consumption at the load you will genuinely run matters more than the headline price
  • Service contract terms, oil and filter intervals, and how running hours are recorded and verified
  • Shortened life and injector fouling from a set that is chronically underloaded
  • Whether spares for that engine family remain available in the district in year eight

How a pool for this runs

1
Aggregate the demand. Institutions register a requirement and a timeline. Nothing is committed and nothing is paid — the pool simply establishes how much demand exists in one window.
2
Standardise the specification. One technical specification is written for the pooled requirement, so every bidder quotes the same machine. Clinical and engineering specification is never traded away for price.
3
Qualify the suppliers. OEMs and authorised distributors are qualified on manufacturer authorisation, past performance, end-user certificates, financials and demonstration — before any price is opened.
4
Run the price competition. Only technically qualified bidders enter an online reverse auction, with a minimum decrement and automatic extension so the close cannot be sniped.
5
Award on ten-year cost. Lowest is judged on total cost of ownership over ten years — machine, turnkey, software, accessories, transport, insurance, taxes, warranty, maintenance contract, tubes, uptime and training.
6
Buy directly, individually. Each institution raises its own purchase order against the negotiated price and pays the OEM or dealer directly. buytogethr never takes title, never holds stock and never holds your money.
