In energy and infrastructure, an EPC contract appoints a single contractor to engineer the design, procure every component and construct the facility, handing the owner a completed plant at a guaranteed price by a guaranteed date. The World Bank's PPP resources describe the model's point precisely: the owner gets a single point of responsibility and price certainty; the contractor gets paid for absorbing the delivery risk World Bank PPP.
Nothing here concerns energy certificates. If a landlord sent you, the certificate territory starts at the other EPC.
The turnkey bargain
| Risk | Held by |
|---|---|
| Design adequacy and fitness for purpose | Contractor |
| Procurement price and supply chain | Contractor |
| Construction cost overruns | Contractor (lump sum) |
| Schedule, backed by delay liquidated damages | Contractor |
| Performance guarantees (output, efficiency), backed by performance LDs | Contractor |
| Site data errors, in the strictest forms | Largely contractor |
| Payment, permits typically, and force majeure allocation | Owner, per contract |
Where the model rules
Power generation, oil and gas, petrochemicals, transmission, desalination, increasingly large-scale renewables and battery storage: sectors where lenders finance against a completed asset's revenue and therefore demand the single-point wrap an EPC contract provides World Bank PPP. Project finance without an EPC wrap (or an equivalent completion guarantee) is the exception, not the rule.
The FIDIC Silver Book
FIDIC's Conditions of Contract for EPC/Turnkey Projects, the Silver Book, is the internationally recognised standard form for this model FIDIC. Its signature is deliberate one-sidedness: risk sits with the contractor to a degree FIDIC itself flags as suitable only where bidders can price it, in exchange for the owner's certainty. The price of certainty is, naturally, priced in.
EPC versus its rival
The standing industry comparison is with EPCM, where the "contractor" is a manager rather than a wrap-provider: EPC vs EPCM takes the two models apart. For every other meaning of the acronym, the disambiguation index is one hop away.
