2.Introduction
2.1Background
The Standard Capacity Product (SCP) is effective on January 1, 2010, as described in CAISO Tariff Section 40.9. SCP incorporates resource availability standards and incentives into the ISO Tariff to facilitate contracting for Resource Adequacy (RA) Capacity. SCP also enhances grid reliability and market efficiency by providing an incentive for RA Resources to be available during peak hours.
SCP is a set of attributes defined in the CAISO tariff which specify the Availability Standard, Non-Availability Charges and Availability Incentive Payments applied to non-exempt RA capacity. There is one availability standard applicable to RA resources each month during the RA compliance year. Each monthly Availability Standard is based on the historic availability of the RA resource fleet during a pre-defined set of peak hours during a previous three-year period. At a high level, the CAISO will review the availability of each RA Resource subject to SCP each month to determine whether its meets the Availability Standard applicable for that month. A RA Resource that has a lower availability rate than the Availability Standard minus the tolerance band of 2.5% is subject to a Non-Availability Charge. A RA Resources that has Availability greater than the Availability Standard plus the tolerance band of 2.5% will be eligible for an Availability Incentive Payment.
Demand response resources whose Qualifying Capacity is determined by the California Public Utilities Commission (CPUC) or Local Regulatory Authority that does not adjust the historical outage data to correct for the possible double-counting of Outages will not be subject to SCP. The deferral of these provisions to these types of RA Resources is temporary, and in the future the CAISO will revisit the applicability of SCP provisions to these types of RA Resources.
RA resources may substitute non RA capacity to mitigate the impact of a forced outage or de-rate on its availability calculation. Any substituted capacity must be both available (as stated in SLIC) and, if substituted in DA market, must submit a bid or self schedule for full amount of substitution in DA market.A non-Resource Adequacy Resource that the CAISO approves to substitute for Resource Adequacy Capacity becomes a Resource Adequacy Resource for the duration of the substitution.
2.2Description
The Standard Capacity Product Pre-calculation is the Pre-calculationwhich executes daily the hourly Availability and Sold Quantities that will be used in the subsequent monthly charge codes. This Pre-calculation is predecessor to CC8824 (Monthly Resource Adequacy Standard Capacity Product Settlement) and CC8825(Monthly NRSS Resource Adequacy Standard Capacity Product Settlement).
3.Charge Code Requirements
3.1Business Rules
Bus Req ID / Business Rule1.0 / The Hourly RA MW Available from Resource and total Availability Assessment Hours of month includes only peak hours. In essence, the CAISO will sum the MW that are available in the month for only the defined Availability Assessment Hours.
1.1 / Availability for each RA resource for each month will be determined by calculating: (a) the total RA Capacity MW available over all Availability Assessment Hours of the month, divided by (b) the total RA Capacity MW designated in the Supply Plan for the same hours
1.2 / A tolerance band of 5.0% is used around the Availability Standard (2.5% on either side of the Availability Standard value) to eliminate the calculation and assessment of Non-Availability Charges and Availability Incentive Payments in very small amounts.
2.0 / SCP Non-Availability Charges and Availability Incentive Payments apply to the Local Capacity Area RA capacity submitted by a Loadfollowing MSS in an annual Resource Adequacy Plan and to the Local Capacity Area RA Capacity of a Modified Reserve Sharing LSE.
3.0 / The eligible substitution quantity is calculated as the minimum of the bid and the substituted capacity in DA market. The bidding is not required for RT substitution.
