Nev. Rev. Stat. § 244A.701
A county may issue bonds to finance solely the costs of studies, surveys and options with respect to a project for the generation and transmission of electricity. Before doing so, the county shall arrange for the repayment of those costs under an agreement or agreements which may provide for the purchase by the obligor or obligors thereunder of the studies, surveys and options through payments sufficient to pay the principal of and interest on the bonds issued to finance those costs if and to the extent the principal of and interest on such bonds are not paid from the proceeds of additional bonds issued to finance the remaining costs of the project. If the obligor or obligors decide that the project is not feasible, they shall pay the costs of the studies, surveys and options within 1 year. Such agreements may also include a commitment or agreement by the county to enter into contracts at a later date for the sale of all or part of the capacity of the project to or for the use of the transmitting facilities of the project by the obligors and for the construction and operation of such project by one or more purchasers of capacity of the project. The terms and provisions of such contracts to be executed at a later date must be approved by the board of county commissioners at the time of or before the first issuance of bonds.
