and Intertie location. These IDs are then placed in the CAISO’s Master File to facilitate participation of such resources. Attachment B, titled “Master File Update Procedures” in the Market Instruments BPM provides the details regarding the setup and maintenance of System Resources as well as a description of the Market Participant data elements contained in the Master File. Participating Load Loads that are bid into the Market as resources are known as Participating Loads. The definition of a Participating Load is given in Appendix A of the Tariff as follows: “An entity, including an entity with Pumping Load, providing Curtailable Demand, which has undertaken in writing by execution of a Participating Load Agreement to comply with all applicable provisions of the CAISO Tariff.” In the FNM a non-aggregated Participating Load is modeled as a part of the nodal Load modeled at a particular Node. The overall Load MW/MVAR values may be measured at the locations shown. A Participating Load is a registered nodal Load with meter for participation in CAISO’s Energy and Non-Spinning Reserve AS Markets. Each Participating Load has one market resource record defined in the Master File with one physical member. The Master File contains information as to whether this is the only end Load at this location, and other information to allow submission of IFM Bid information for the Participating Loads. Each market resource is scheduled by a single SC. In the case of a Participating Load, the market resource may represent only a fraction of the Demand that exists at a Take-Out Point. Participating Loads may include aggregations across multiple Take-Out Points as discussed in Section 4.2.3.7. While POD loss adjustments are not made for Loads as they are for Generating Units, both Participating Loads and Generating Units have PNodes that are established for scheduling and Settlement in CAISO Markets. These PNodes might not be the same as the CNode where the resource is connected. Settlement is made on the basis of the market resource at the Point of Delivery. Participating Loads can be set up to participate as a Pumped Storage unit or alternatively under an arrangement that uses a similar bidding approach to the way NonParticipating Load is structured.
Data Bases Supporting the FNM Update Process This section provides a general description of the data bases utilized and updated as part of the CAISO’s process to maintain and update the FNM for use in the EMS, IFM and RTM systems. This includes the data bases which are continually maintained and updated based on data and information provided by Market Participants to the CAISO, as well as data bases that are only updated as part of each periodic FNM update cycle. Exhibit 5-2 provides an overview of the data bases utilized for the FNM maintenance and update process. Exhibit 52: FNM Data Bases Resource Interconnection Management System (RIMS) Data Base The RIMS data base is used by the CAISO to track all new transmission and generation projects, or modification to existing transmission and generation facilities. For transmission projects, the input into the RIMS data base is performed by the PTOs or other transmission entities concerning additions or changes that are scheduled to be made to the transmission system. Such information includes nature of projects, specific components or phases of these projects, and the target date for energizing and interconnecting the transmission projects or its various phases with the grid. For generation projects, the input is from generation owners and developers through their application to interconnect new or upgraded generation facilities to the grid. This includes the nature of the project and target date for interconnecting the new or modified generation facility to the grid. Transmission projects are tracked entirely within the RIMS data base from initial reporting to the CAISO by the PTO or transmission entity through the completion and full integration of the transmission project into the FNM. Generation projects are tracked initially through the RIMS data base from the initial application through the interconnection study and approval processes. Once a generation project is approved by the CAISO for implementation, its detailed progress and implementation phases are then tracked through the Participating Generator Interconnection (PGI) data base (discussed below) through the completion of the project and full integration of the generation project in the FNM. The RIMS data base includes only summary tracking of generation projects during the implementation phase with regard to certain aspects related to update of the “wires” model portion of the FNM Access is provided through an interface via a secure web-enabled database environment to view and make changes to CAISO RIMS data from various levels of CAISO, PTO, and Market
