The calculation for RMR Standby Price (RMRSBPR) has changed with NPRR810:

Before NPRR810

After NPRR810

RMRSBPR _{q, r}               =     (RMRMNFNCC _{q, r} * (1 + RMRIF * RMRCRF _{q, r} * RMRARF _{q, r}) + RMRMNFCC _{q, r} ) / MH _{q, r}

·         The variable RMRMNFC has been replaced with RMRMNFNCC

·         The variable RMRMNFCC has been added

Variable	Unit	Definition
RMRMNFNCC q, r	$	Reliability Must-Run Monthly Non-Fuel Non-Capital Cost per QSE per Resource—The actual non-capital and non-fuel Eligible Cost of RMR Unit r represented by QSE q, for the month.  Where for a Combined Cycle Train, the Resource r is the Combined Cycle Train.
RMRMNFCC q, r	$	Reliability Must-Run Monthly Non-Fuel Capital Cost per QSE per Resource—The actual non-fuel and capital Eligible Cost of RMR Unit r represented by QSE q, for the month.  Where for a Combined Cycle Train, the Resource r is the Combined Cycle Train.  Notwithstanding the above, reservation and transportation costs associated with firm fuel supplies as described in paragraph (1)(a)(vi) of Section 3.14.1.10, Eligible Costs, shall be included herein.
