Pinon Pine IGCC project status update, August 1992

摘要

Since the recent (August, 1992) execution of the Cooperative Agreement, the major focus of work has been on critical-path environmental permitting activities, both related to the NEPA process as well as state and local activities. Pending approval of the project by the Nevada Public Service Commission, detailed engineering activities will commence in November. Federal funding of the project automatically invokes environmental review under the National Environmental Policy Act (NEPA). This project will require an Environmental Impact Statement, or EIS, with DOE as the lead agency for the NEPA reviews. The project must also be approved by the Nevada Public Service Commission (PSCN) in the state's Resource Planning process. As shown in the project schedule, Figure 4 below, SPPCo. expects to have the combustion turbine portion of the plant on line by late 1994, configured as a simple-cycle natural gas machine with either No. 2 diesel or propane being utilized as backup fuel. By phasing construction in this manner, SPPCo. gains approximately 45 MWe of peaking power capacity to match projections of customer loads. The gasifier, heat recovery steam generator (HRSG), and the balance of the IGCC plant will be commissioned in late 1996. A DOE demonstration period of 42 months is planned.
