CAISO Market Initiatives
CAISO 72 Hour RUC
The CAISO 72 Hour RUC is an initiative which extends the current RUC unit commitment time horizon by up to an additional 48 hours to span over a configurable 72 hour period. This initiative aims to provide two market benefits: 1) increase economic efficiency by reducing the commitment costs caused by additional start-up cost due to uneconomic cycling; and 2) increase grid reliability reducing the amount of cycling of resources which results in additional stress on the resources and may increase times resources are unavailable. The ISO is anticipating implementing this initiative in Fall 2011. This new initiative has no impact on the APX MarketSuite.
CAISO Credit Reform in Organized Energy Markets - FERC Order 741
All new and existing market participants will need to provide to the CAISO an executed copy of annual certification for Credit Management. This certification shall be provided before an entity is eligible to participate in the CAISO Markets and is to be submitted to the CAISO during the Scheduling Coordinator certification processes. Thereafter, the certification is to be submitted every calendar year.

CAISO Credit Reform in Organized Energy Markets - Settlements Process Timeline Change
In an effort to become compliant with FERC's rules on Credit Reforms in Organized Wholesale Electric Markets, the CAISO is implementing a shorter settlements timeline. In the Credit Reform Order, the commission adopted rules that require RTOs and ISOs to implement shortened settlement timelines to establish billing periods of no more than seven days and settlement periods of no more than seven days after issuance of the bills.
Below are tables which show the proposed new Statement, Meter, and Dispute timelines that are effective October 1, 2011.
See attached link for the ISO's Proposed Payment Calendar.

T+9M |
The T+3B statement will not use actual meter data; it will be based solely on estimated meter data. The estimated meter data for load is DA schedule plus 15% and the estimated meter data for generation is based on total expected energy. This means that there will not be any RT Uninstructed Energy Settlement (charge code 6475) for generation on the T+3B statement.
New Dispute Deadlines
| Statement Publication |
Settlement Dispute Deadline |
Settlement Dispute Scope |
| T+12B |

| T+9M (T+194B) |
T+10M (T+216B) |
Incremental Changes Only |
Disputes on the T+3B initial statement are not allowed as this statement is solely based on CAISO Estimated Settlement Quality Meter Data.
APX will revise the APX MarketSuite® to harvest and load the new statement and determinant files as well as modify its reports and the Settlement Comparison application to include the new versions. For those that subscribe to the Shadow and Estimated Settlements service, APX will also be modifying its shadow logic to use estimated meter data in the T+3B statement, while using actual meter data in the T+2 estimate.

CAISO Reliability Demand Response Product
The Reliability Demand Response Product (RDRP) is a wholesale demand response product that enables emergency responsive demand response resources to integrate into the CAISO market and operations. The RDRP design ensures compatibility with, and the integration of, existing retail emergency-triggered demand response programs, such as interruptible load programs, direct-load contract programs like air-conditioning cycling, and agriculture pumping programs. This product is designed to integrate large or aggregated demand response resources that may be configured to offer energy economically in the day-ahead market, and as a minimum requirement, can response to a reliability event in
real-time. The RDRP resources will have a unique resource ID, must respond to dispatch instructions, and will be modeled like a supply resource, using the same infrastructure as designed for Proxy Demand Resource products. Like Proxy Demand Resources, RDRP resources will be eligible to set the LMP. This new product is expected to launch in the Spring of 2012.

CAISO GMC Rate Structure Change
Effective January 1, 2012, the CAISO is proposing to make the following revisions to the GMC rate design in an effort to more closely align the cost allocation categories with the ISO's nodal market.
The ISO proposes to reduce the number of formula-rate charges from seven to three: market services, system operations, and congestion revenue rights ("CRR") services. The proposed GMC rate structure also includes four administrative fees, a fixed charge for transmission ownership rights (TOR's) and a time limited exemption from the system operations charge for certain power supply contracts. The CAISO has asked FERC to rule on the tariff changes by September 30, 2011 for a planned implementation date of January 1, 2012.
Once the GMC charge codes for 2012 are finalized, APX will revise the Shadow and Estimated Settlements service to calculate the GMC charge codes based on the new CAISO configuration.
