The purpose of this document is to capture the requirements and design specification for a Charge Code in one document.
2.1 Background
A flexible ramping constraint applies as part of the market optimization for the real-time processes. This constraint addresses certain reliability and operational issues observed in the ISO’s operation of the grid.
In accordance with the CAISO Tariff, resources that resolve the flexible ramping constraint are to be compensated in Settlements at the Flexible Ramping Constraint
Derived Price. The Flexible Ramping Constraint Derived Price is equal to the lesser of:
1) $800/MWh; or
2) the greater of: a) zero, or b) Real-Time Spinning Reserve Ancillary Service
Marginal Price; or c) the Flexible Ramping Constraint Shadow Price minus seventy-five percent of the maximum of zero or the simple average Real-Time
System Marginal Energy Cost for each of the three five-minute RTD intervals in the applicable fifteen-minute FMM interval.
The Flexible Ramping Constraint Shadow Price is the reduction of the total Energy and
Ancillary Services procurement cost associated with a marginal change at each constraint for the individual Balancing Authority Areas (BAA) in the EIM Area and applicable groupings of those areas in which the constraint is enforced, which will be equal to zero
(0) if the Flexible Ramping Constraint is not binding.
The CAISO will determine the Flexible Ramping Constraint costs for each constraint as the product of:
1) the resource-specific total Flexible Ramping Constraint costs, calculated as the total compensation, net of rescinded amounts; and
2) the ratio of the Flexible Ramping Constraint Shadow Price to the total Flexible
Ramping Constraint Shadow Price
For each constraint and each BAA in the EIM Area, the CAISO will determine the Flexible
Ramping Constraint costs attributable to that BAA for which the applicable constraint(s) were binding in the applicable interval, based on the ratio of the BAA ’s requirement to its contribution to the individual constraint or group of constraints to which that BAA contributes, and determine each BAA ’s apportionment of Flexible Ramping Constraint costs as the summation of the BAA ’s amounts.
The costs associated with such compensation, as netted by BAA, are allocated to the
CAISO BAA as twenty-five percent of daily gross negative supply deviations and seventy-

Date: 7/7/14 five percent of hourly measured demand, which consists of metered load and exports. At the end of each month, the costs allocated to daily gross negative supply deviations will be reversed and re-allocated to monthly gross negative supply deviations. The associated costs for individual EIM BAAs are allocated to the EIM Entity Scheduling Coordinator(s).
2.2 Description
In this Charge Code (CC) 7056 Flexible Ramp Cost Allocation, the costs from CC 7050
Flexible Ramp Up Capacity Payment, net of the rescission payment from CC 7024
Flexible Ramp Up No Pay Capacity Charge, are apportioned to the Balancing Authority
Area (BAA) based on the ratio of the proportion of the shadow price contribution of each constraint or group of constraints resolved by a resource to the total shadow price across all constraints, and by the ratio of a BAA ’s Flexible Ramp requirement to its total contribution toward relieving a Flexible Ramp Constraint or constraint group. The total output costs for the CAISO BAA are allocated seventy-five percent to hourly resourcelevel Measured Demand without exemption to the demand quantities, and twenty-five percent to daily gross negative supply deviation. The total output costs for the EIM BAA are allocated to the EIM Entity Scheduling Coordinator.

Business Rule
For the CAISO BAA, the costs of flexible ramping capacity payments, as apportioned to CAISO and net of the rescission No Pay payment, are allocated seventy-five percent to hourly resource-level Measured Demand without exemption to the demand quantities, and twenty-five percent to daily gross negative supply deviation.
2.0
There shall be no exemption to the hourly Measured Demand quantities for the purpose of allocating the flexible ramping capacity payments to
Scheduling Coordinators in the CAISO BAA.

The daily gross negative supply deviation is calculated per resource in the
CAISO BAA as the sum of total negative Settlement Interval UIE plus total negative Settlement Interval import Operational Adjustments
The net imbalance amount calculated as the sum of the final Settlement amounts for Charge Codes 7050 and 7056 in a given trade interval is attributed to rounding and must be output to CC 4989 Daily Rounding
Adjustment Allocation.
The costs of flexible ramping capacity payments, as apportioned to an EIM

Each resource with awarded flexible ramping capacity may resolve Flexible
Ramping Constraints associated with multiple BAAs within the EIM Area, or just one. This potential combination of Flexible Ramping Constraints is referred to as a group of constraints in which the resource participates.
Each Flexible Ramping Constraint corresponds to a BAA or group of BAAs.
All permutations of BAAs within the EIM Area are taken into consideration.
The total Flexible Ramping Constraint Shadow Price is the resource-specific summation of the flexible ramping shadow prices of all constraints in the group of constraints which the resource may resolve. This is the same shadow price used in the calculation of compensation in Charge Code 7050.
The Flexible Ramping Constraint Shadow Price is a constituent element of the aforementioned total – it is the shadow price associated with one
Flexible Ramping Constraint or group of such constraints.
For the purposes of this Charge Code 7056, the Flexible Ramping
Constraint Shadow Price is shown at the resource level. When a resource resolves a constraint pertaining to multiple BAAs, the shadow price is separated by BAA in proportion to the BAA ’s Flexible Ramping Constraint requirement quantity, as determined by the CAISO market software.
The Flexible Ramping Constraint costs, net of rescission, are apportioned to
Flexible Ramping Constraint or group of constraints, as the ratio of the individual Flexible Ramping Constraint Shadow Price to the total Flexible
Ramping Constraint Shadow Price
