ABSTRACT
This chapter focuses solely on the PV resources that our utility has determined are needed to serve 100% of its GWh load by the target year. The trend of PV costs from 2010 through 2022 is examined first. Next, a look is taken at the tax credits for PV that were provided by the 2022 Inflation Reduction Act (IRA). This discussion includes an evaluation of how significant those tax credits are by reworking the economic analyses of the resource plans presented in Part I of this book after accounting for the 2022 IRA's tax credits for PV. Then the issue of the firm capacity value of PV is examined, which shows that PV's firm capacity value declines as more MW of PV are added by the utility. This characteristic of PV is then accounted for to determine what it means for our utility's summer and winter reserve margin calculations.
