This section covers the construction of all portions of a generating plant, including plant buildings and the generator step-up transformer. Generally, the transmission switchyard will be covered under this section during initial construction of the plant. Subpart C of this part covers subsequent modifications to transmission switchyards. Warehouses and equipment service type buildings are covered under subpart E of this part.

Contract forms. (1) The borrower shall use RUS Form 198, Equipment Contract, for the purchase of generating plant equipment in the amount of $5,000,000 or more and for any generating plant equipment contract requiring RUS approval.

The borrower shall use RUS Form 200, Construction Contract—Generating, for generating project construction contracts in the amount of $5,000,000 or more and for any generating project construction contract requiring RUS approval.

The borrower may, in its discretion, use other contract forms or written purchase order forms for those contracts in amounts of less than $5,000,000 and that do not require RUS approval.

Procurement procedures. (1) It is the responsibility of each borrower to determine the procurement method that best meets its needs to award contracts in amounts of less than $5,000,000 each.

If the amount of the contract is $5,000,000 or more or if the contract requires RUS approval, the borrower must use formal or informal competitive bidding to award the contract.

Where formal or informal competitive bidding is not applicable, or does not result in a responsive bid, multiparty negotiation may be used only after RUS approval is obtained.

Contract approval. During the early stages of generating plant design or project design, RUS will, in consultation with the borrower and its consulting engineer, identify the specific contracts which require RUS approval based on information supplied in the plant design manual. The following are typical contracts for each type of generating project which will require RUS approval. Although engineering services are not covered by this part, they are listed in this paragraph (d) to emphasize that RUS approval is required for all major generating station engineering service contracts in accordance with applicable RUS rules. For types of projects not shown, such as nuclear and alternate energy projects, RUS will identify the specific contracts which will require RUS approval on a case by case basis.

Fossil generating stations.
