2.Overview of Telemetry to the CAISO
Welcome to the Overview of Telemetry section of the BPM for Direct Telemetry. In this section you will find the following information:
A description of the telemetry process;
A diagram of the telemetry installation and validation process; and
A diagram of the flow of telemetrydata
2.1Telemetry Process
This BPM sets forth requirements for the provision of real-time data to the CAISO applicable to all Participating Generators’ Generating Units providing Ancillary Services (including Regulation) or Energy in the CAISO’s markets. This BPM also applies to Participating Loads and Proxy Demand Resources participating in the CAISO’s markets. This BPM describes the process and procedures used by the CAISO to obtain real-time data from the resources of Participating Generators,Participating Loads, Proxy Demand Resources, and Scheduling Coordinatorsrepresenting these entities for operating the CAISO Balancing Authority Area reliably and balancing the CAISO Markets.
A Generator with a Generating Unit connected to the electric grid within the CAISO Balancing Authority Area that (1) has a capacity of ten (10) megawatts (MW) or greater that is not exempt pursuant to the CAISO Tariff, (2) provides Ancillary Services, or (3) is an Eligible Intermittent Resource not exempt pursuant to the CAISO Tariff must install, in accordance with the requirements specified in this BPM, equipment and/or software that can interface with the CAISO’s Energy Management System (EMS) to supply telemetered real-time data. That Remote Intelligence Gateway (RIG) or equivalent will serve as the primary means for secure communications and direct control between the Generator’s Generating Unit and the CAISO’s EMS as a prerequisite for participation in any of the CAISO markets requiring real-time data. In some circumstances, the CAISO allows for aggregation of Generating Units and the associated direct telemetry. While this BPM does not address all issues related to Aggregated Units, it does address the required points for Aggregated Units herein. The resources of Participating Loads and Proxy Demand Resources are also subject to these requirements for telemetry of real-time data.
This BPM provides information regarding:
The CAISO installation requirements for telemetryfacilities;
How the CAISO validatesdirect telemetry facilities for Participating Generators,Participating Loads, Proxy Demand Resources,and Scheduling Coordinators representing these entities; and
Direct telemetry validation, testing, and maintenance requirements for telemetry for resource owners’ facilities participating in the CAISO markets.
2.2Overview of Installation & Validation of Telemetry
Exhibit 2-1 illustrates the process for installation and validating telemetry installation for owners of resources required to provide real-time telemetry.
Exhibit 21: Overview of Installation and Validation of Telemetry Installations
2.3Overview of Flow of Real-time Data
Exhibit 2-2 illustrates the flow of real-time telemetry data between resources and the CAISO’s EMS and from the CAISO’s EMS to other CAISO systems.
Exhibit 22: Overview of Real-Time Telemetry Data Flow
2.4Organization of the BPM
The following Sections describe the respective responsibilities of the CAISO, Participating Generators,Participating Loads, Proxy Demand Resources,and Scheduling Coordinators representing these entities for provision of direct telemetry. Sections 4 through 17describe provisions for configuration, installation, and validation of telemetry facilitiesfor resources providing Ancillary Services or Energy only, and for wind, solar,and Proxy Demand Resources.

3.CAISO Responsibilities
Welcome to the CAISO Responsibilities section of the BPM for Direct Telemetry. In this section you will find the following information:
An overview of CAISO responsibilities
A description of the installation and point to point validation process for telemetry facilities
A description of the documentation requirements
A description of the testing and completion requirements
3.1Overview of CAISO Responsibilities
CAISO Tariff Section 7.6.1(d) Actions For Maintaining Reliability Of CAISO Controlled Grid
Section 7.6.1(d) of the CAISO Tariff provides the CAISO authority to obtain the control over Generating Units that it needs to control the CAISO Controlled Grid and maintain reliability by ensuring that sufficient Energy and Ancillary Services are procured through the CAISO Markets. That provision requires each Participating Generator to take, at the direction of the CAISO, such actions affecting such Generator as the CAISO determines to be necessary to maintain the reliability of the CAISO Controlled Grid. Such actions include (but are not limited to) the provision of communications, telemetry and direct control requirements,including the establishment of a direct communication link from the control roomof the Generator to the CAISO in a manner that ensures that the CAISO will havethe ability to direct the operations of theGenerator as necessary to maintain the reliability of the CAISO Controlled Grid,except that a Participating Generator will be exempt from these requirementswith regard to any GeneratingUnit with a rated capacity of less than ten (10) MW, unless that Generating Unitis certified by the CAISO to provide Ancillary Services.
This BPM sets forth the provisions by which the CAISO implements the foregoing responsibilities for direct telemetry.
3.2Telemetry Validation
The CAISO has overall responsibility for validating real-time data to the CAISO. Some of this responsibility is accomplished by the responsibilities placed on the resource owner (or aggregator, in the case of some resources), which may include responsibilities satisfied by the Scheduling Coordinator for the resource. This Section 3.2 summarizes the respective certification responsibilities of the CAISO and the resource owner (or aggregator or Scheduling Coordinator, as applicable).
3.2.1Overview of Telemetry Installation Validation Process
Exhibit 3-1 provides a high level illustration of the overall validation process for telemetryfacilities.
Exhibit 31: Telemetry Installation Validation Process
3.2.2CAISO Certification Responsibilities
The CAISO does not accept real-time telemetrydata from a resource unless that telemetry data is produced by telemetry facilities that have beenvalidated in accordance with the CAISO Tariff and this BPM.
3.2.2.1Documentation Requirements
To initiate the submission process in the scheduled FNM build, theresource owner must provide the following information to the CAISO Generator Connection Project Manager:

Examples would be the telemetry used and how it communicates with the CAISO EMS. The size of the Generating Unit and associated Load should also be included. Other examples include the Point of delivery of Energy to the CAISO Controlled Grid.
- Communication information: Provide the IP address of the telemetry device and all router ports if using the ECN. Otherwise only the ISP IP address.
3.2.2.2CAISO Review of Documentation
If there are any discrepancies between the CAISO RIG Engineering drawings on file and the actual telemetry installation, then the resource owner or authorized resource owner representative must document that discrepancy and revise the drawings provided to the CAISO. Where the resource owner integrator discovers a discrepancy, that person must notify the CAISO and the resource ownerof the discrepancy within 24 hours of the discovery.
If the resource owner doesn’t provide all the required documentation set forth in Section 3.2.2.1 for a FNM build then the CAISO will notify the resource owner. If the documentation that is required is not delivered within the FNM build time line, the opportunity for the resource to participate in the CAISO markets will be deferred to the next FNM build time line. The time lines dates are communicated to the resource owner at the time the Grid Connection Project Manager receives a request to participate.
