The amount shown for 2015 is the PPI ATRR effective as of 6/1/15. Therefore, the 2015 Annual Cost of $24.488 /kw-Yr is the current Schedule 9 rate in effect for the AMIL Pricing Zone. PPI has filed at FERC to begin using a forward looking Attachment O effective 1/1/16. PPI’s preliminary revenue requirement for 2016 is reflected above along with the projected 2016 revenue requirements for AIC and ATXI. The total 2016 projected Schedule 9 rate for the AMIL Pricing Zone is $31.576/kW-Yr. 16 QUESTIONS?
