## Business As Usual (BAU) Case

**LNB Case (Low NOx Burners, Overfire Air)**

**SNCR Case (Selective Non-Catalytic Reduction) Economic Analysis of Proposed EPA BART Determination** 

**on Four Corners Power Plant**

This case defines the incremental cost impacts of investment made to plant that are anticipated with or without additional controls (i.e. SNCR or SCR). The LNB Case capital and operating cost parameters include the plant - as its **expected** to perform - modified for inflation, over a 25 year assessment period, with the installation of LNB on units 1 and 2, and LNB/OFA on units 3-5. **The key modeling outputs are costs for power in discounted dollars, total undiscounted dollar, and $/MWh for all cases.**  **- Cost impacts to water rates, retail power rates, or other downstream costs/prices are not considered** 

This case defines the plant **as it was in 2009** . This plant configuration as it was in the 2009 reporting year will have created the cost of generation metrics filed by the operator in its annual FERC F-1 filings.

This case adds to the BAU Case the SCR related capital investment and increased operational expense. This case reports out total case costs as well incremental cost.



## SCR Case (Selective Catalytic Reduction)

**Market Trend Cases (Low, Mid, and High)**

Additional Factors (i.e. CO2 compliance, MACT compliance, Ash/CCW handling costs) are not considered in this draft model Major equipment replacement or capital investment to extend current BAU plant life is not assumed This case adds to the BAU Case the SCR related capital investment and increased operational expense. This case reports out total case costs as well incremental cost.

These cases are included to allow comparison of the 25 year costs between retrofit options, as described above, and the estimated cost of procuring power from the market to replace the volumes unavailable in the case of a plant shut down expense. This case reports out total case costs as well incremental cost.E C/R Energy Strategies E.N. 1109 **FOUR CORNERS POWER PLANT SCR COST ECONOMIC ANALYSIS**
