The parabolic trough performance model calculates the solar field thermal delivery on an hourly basis. The solar energy is stored in the thermal storage system. The model has a dispatch strategy to determine when the power plant should be operated. Solar energy can be dispatched for nighttime electric production. The model includes thermal losses from the solar plant and thermal storage and calculates the parasitic electric consumption of the plant for both online and offline. 5.2 Financial Assumptions The trough model also calculates the project economics. For the analysis, we assumed that the project would use conventional independent power project (IPP) financing. The project financing assumptions used in this analysis are shown in Table 13. The project assumes that a power purchase agreement (PPA) has been set up between the project owner and a utility or a large institutional customer. The PPA is structured so that a single energy price is paid for power that escalates each year with inflation. The analysis assumes 2.8% annual inflation. Annual insurance costs assumed are set at 0.5% of capital cost. This is consistent with insurance costs from the SEGS plants. IPP financing relies on the revenue stream from the project as the collateral for the loan or project debt. As such, there are special constraints placed on the project. Typically, there needs to be a long-term power purchase agreement for at least the term of the debt. Because the debt relies on the revenues from the contract, they require that the net project revenues after paying O&M expenses during any year be larger than the required debt payment that year. The debt service coverage ratio (DSCR) is the ratio of net income after O&M expenses over the debt payment. Typically, DSCRs of 1.3 to 1.5 are required for IPP projects. Because solar projects are very capital intensive, this constraint becomes very important in the optimization between debt and equity financing. The project economics are based on an assumed 20-year project life and 12- year debt terms. The analysis assumes that the IPP financing takes advantage of the special state and federal financing incentives that are available for trough power plants. These include the 10% federal solar investment tax credit, the 5-year federal accelerated depreciation for federal income tax, and the California property tax exclusion for solar equipment. The trough model uses these economic assumptions and the finance constraints to select the optimum mix of debt and equity financing required to minimize the first-year energy price. The first-year energy price is the economic figure of merit used in the remainder of the report to evaluate different plant design configurations. 32PDF Image | Modular Trough Power Plant Cycle and Systems Analysis
