IV. CAPITAL, C ST ESTIMATES Costs for the gas CT and CC plants are broken into two categories: capital costs and fixed operation and maintenance (“FOM’) costs. Capital costs are incurred when constructing the power plant, before the commercial online date. Power plant developers typically hire an engineering, procurement, and construction (“EPC”) company to complete construction and to ensure the plant operates properly. The costs of EPC contractor services, as well as the costs of major Owner-Furnished Equipment (“OFE’), were estimated by CH2M HILL as suimarized in Section1V.Abelowforplantpropercosts. Thereareadditionalowner’scapitalcoststhatagas CT or CC developer would face, such as the purchasing of land, development costs, interconnection costs, start-up kel, and owner’s contingency which we estimate in Section 1V.B. A. PLANT PROPER CAPITAL COSTS Plant proper costs include most of the costs required to engineer and construct a plant including the costs of major equipment and EPC services. CH2M HILL developed engineering cost estimates for the reference technology and sensitivity case estimates in our study as summarized here. Full docuinentation and supporting details regarding these estimates are included as Appendices A and B for the simple-cycle and combined-cycle technologies respectively. 1. Plant Developer and Contractor Arrangements We asked CH2M HILL to assume that a plant owner will contract with an EPC services provider to engineer and construct the project. The EPC contractor would then be responsible for procuring all equipment and materials with the exception of major Owner-Furnished Equipment. The OFE consists of the plant gas turbines and SCR units for the simple-cycle plants, and the gas turbines, steam turbines, and HRSG units in the combined-cycle case. The OFE in our scenario is purchased by the owner and then assigned to the EPC contractor, meaning that, while the owner initially orders the equipment, the EPC contractor takes on responsibility for handling delivery and installation of the equipment. We also asked CH2M HILL to assume that the EPC contractor will be taking on all contingency risk associated with cost oveii-uns for all items within their scope. This associated contingency risk includes all contingency risk associated with the assigned OFE including delivery delays, but excludes any Contingency risk associated with potential change orders to the EPC scope. 2. Owner-furnished Equipment and Sales Tax The plant proper costs that will be paid directly by the owner include the costs of OFE and sales tax incurred in procuring the OFE, as well as the sales tax incurred by the EPC contractor and passed through to the owner. Table 20 summarizes these direct owner’s costs for the simple- cycle plant, with OFE including two 7FA.05 gas turbines and a hot SCR. Table 21 summarizes these costs for the combined-cycle plant, with the OFE including two 7FA.05 gas turbines, a steam turbine, and two HRSG units. These owner costs are incurred over the capital drawdown schedule as summarized in Section IV.A.4. Additional supporting docurnentation for these costs is included in Appendix A for the simple-cycle and Appendix B for the combined-cycle configurations. 19
