RELIABILITY MUST-RUN PAYMENTS AND CHARGES COMPUTATION
H 1	Purpose of the Payments and Charges
The Reliability Must-Run Payments are the amounts which the ISO is obligated to pay to the owners of Reliability Must-Run Units under or arising out of Reliability Must-Run Contracts.  The Reliability Must-Run Charges enable the ISO to recover those amounts from relevant Participating TOs.
H 2	Calculation of Payments and Charges
H 2.1	Reliability Must-Run Payments.
Invoices submitted by Reliability Must-Run Owners to the ISO must be calculated as follows:
(a)	Agreement A:
The Reliability Must-Run Payment under Agreement A for each month for each Owner shall be the total of the payments for that month for each Reliability Must-Run Unit owned by the Owner to which the Conditions of Must-Run Agreement A apply calculated in accordance with those Conditions.  The Agreement A payment for Reliability Must-Run Owner o for Reliability Must-Run Unit u for month m shall be calculated as follows:

The total payment to each Owner for Reliability Must-Run services under Agreement A for a given month shall be calculated by summing all the payments for the month for the Reliability Must
-Run Units owned by the Owner to which Agreement A applies.  The payment for Owner o for month m shall be calculated as follows:

(b)	Agreement B
The Reliability Must-Run Payment under Agreement B for each month for each Owner shall be the total of the payments for that month for each Reliability Must-Run Unit owned by the Owner to which the Conditions of Must-Run Agreement B apply calculated in accordance with those Conditions.  The Agreement B payment for Reliability Must-Run Owner o for Reliability Must-Run Unit u for month m shall be calculated as follows:

The total payment to each Owner for Reliability Must-Run services under Agreement B for a given month shall be calculated by summing all the payments for the month for the Reliability Must-Run Units owned by the Owner to which Agreement B applies.  The payment for Owner o for month m shall be calculated as follows:

(c)	Agreement C
The Reliability Must-Run Payment under Agreement C for each month for each Owner shall be the total of the payments for that month for each Reliability Must-Run Unit owned by the Owner to which the Conditions of Must-Run Agreement C apply calculated in accordance with those Conditions.  The Agreement C payment for Reliability Must-Run Owner o for Reliability Must-Run Unit u for month m shall be calculated as follows:

The total payment to each Owner for Reliability Must-Run services under Agreement C for a given month shall be calculated by summing all the payments for the month for the Reliability Must-Run Units owned by the Owner to which Agreement C applies.  The payment for Owner o for month m shall be calculated as follows:

(d)	Total Payment
The total amount payable to each Owner for each month for Reliability Must-Run services shall be the total of the amounts due to the Owner under Agreements A, B and C for that month.  The total payment for Reliability Must-Run Owner o for month m shall be calculated as follows:

H 2.2	Reliability Must-Run Charges
Each Participating TO shall pay to the ISO the total amount payable by the ISO for each month under the Reliability Must-Run Contracts for the Reliability Must-Run Units located in the Participating TO's Service Area.
The charge to Participating TO n for month m for Reliability Must-Run Unit u located in the Service Area of Participating TO n shall be calculated as follows:
RMRCnmu = RMRPaynmu 
The total charge to each Participating TO for Reliability Must-Run services for a given month shall be calculated by summing all the charges for the month for the Reliability Must-Run Units located in
 the Service Area of the Participating TO.  The charge for Participating TO n for month m shall be calculated as follows:
