Expanding Metering and Telemetry Options Technical Stakeholder Initiative April 24, 2013 Jill Powers, Smart Grid Solutions Manager
Purpose of Today s Meeting Review of straw proposal paper posted 4/18/13 Introduce 5 proposals to expand metering and telemetry options Provide stakeholders opportunity to ask questions Make available subject matter experts for discussion Request for comments Initiative next steps Page 7
To participate in the ISO s wholesale electricity markets, revenue metering and telemetry requirements must be met. Metering Provides interval resource data Essential for settlement of market transactions Telemetry Provides real time monitoring and control Critical for grid and market operations Slide 8
Metering and Telemetry requirements fits participation of traditional system resources. Requirements developed for the monitoring and measurement of large generating resources. Expansion of metering and telemetry methods will facilitate greater market participation for small renewable and distributed energy resources. Emergence of resources aggregated to minimum capacity requirements Slide 9
In 2012, the ISO held a series of technical working sessions. Objective: Obtain feedback on experience in meeting metering and telemetry requirements. Goal: Identify a path forward to support additional options for metering and telemetry Slide 10
Efforts of the working groups identified Issues with current technical and business practice requirements. Summary of issues were categorized to develop a set of opportunities needing to be supported in proposals Business scenarios that may not be currently supported Concentration, flexible aggregation, calculated aggregation, statistical aggregations, sub-metering, shared participation To be architectures resolving technical issues and supporting business scenarios -internet & data concentration Slide 11
Objective and scope of the initiative may not address all identified issues or business scenarios. Develop proposals providing options to meet metering and telemetry requirements Obtain input on the proposals and guidance on priority for implementation Facilitate discussion for further development of additional proposals. Options requiring policy changes or program enhancements Slide 12
Initiative scoped in two phases based on relative complexity of solutions. Phase I: adding flexibility and lower cost options. Alternative communication transport Additional protocol options Expanding ISO metered entity provisions Removing aggregator limitations Phase II: recognizing new service providers Defining Data Concentrator Roles and responsibilities Service capability and level Page 13
Continuation of 2012 efforts begin with the straw proposal stakeholder feedback. Stakeholder Initiative Objective: Develop and obtain input on the proposals expanding options to meet current metering and telemetry requirements. Phase 1 Proposals: Use of Internet for telemetry and meter data transport (2 options) Expand the use of ICCP as an allowable option for RIG aggregators Expand the ability for resources to submit Settlement Quality meter Data Remove RIG Aggregator resource ownership and location limitations Proposals may require Business Practice Manual for Telemetry and Metering updates and potential tariff changes.

Initiative timeline, parallel efforts, and implementation process Jeremy Malekos, Initiative Project Manager
Proposal 1: Use of internet for telemetry and meter data bridging to the ISO Energy Communication Network (ECN) Provides a service option to obtain telecommunications access to and from the ECN through the internet Reduces setup and monthly cost of providing a direct ECN connection. Resource owners determine what communication method is used to access the internet. Requires the installation of a VPN remote access device that would be managed by the ECN service provider Page 16
Proposal 1: Illustration Internet bridging to ECN RIG Customer LAN VPN Remote Access Device SSL encryption Internet Service Provider ECN Secure Gateway ECN Edge Router ISO Network EMS Revenue Meter RQMD MV90 Figure is only an illustration and may not fully represent ISO requirements. Page 17
Proposal 1: Applicability Metering: Meets communication requirements for all resource size and service participation Telemetry: Direct telemetry use of option would be available for resources less than 400 MW in size Page 18
Proposal 1: To mitigate impact of losing telemetry for any single resource additional limits are proposed. Telemetry: ISO is proposing to limit the overall capacity certified to provide regulation services that uses an internet option for direct telemetry. ISO proposes to include a resource size limitation for spinning reserve and regulation Service Total Certified Quantity (MW) Resource Size (MW) Energy Only None <400 MW Non-Spin None < 400 MW Spin None <10 Regulation up <50 <5 Regulation down <50 <5 Page 19

Proposal 2: Use of internet for telemetry and meter data transport directly to the ISO with SSL Provides a service option to obtain telecommunications access to and from the ISO through the internet Reduces setup and monthly cost of providing a direct ECN connection. Resource owners determine what communication method is used to access the internet. Requires meter security certificates and SSL encryption of data Page 22

Proposal 2: Applicability Metering: Meets communication requirements for all resource size and service participation Telemetry: Direct telemetry use of option would be available for resources less than 400 MW in size Page 24
Proposal 2 includes the same limitations for resource size and total capacity as proposal 1 Telemetry : Service Total Certified Quantity (MW) Resource Size (MW) Energy Only None <400 MW Non-Spin None < 400 MW Spin None <10 Regulation up <50 <5 Regulation down <50 <5 Page 25

Single point of failure?
Proposal 3: Expand the use of Inter-Control Center Communication Protocol (ICCP) as an allowable option for RIG aggregation Provides an option for aggregators with the ability to exchange a volume of real-time data and control command communication using ICCP Requires ECN Option available only to an aggregator with >10 MW of current or developing resources Requires evaluation and approval by ISO Page 28
Proposal 3: Illustration ICCP Option Illustration depict aggregation of: Individual resource Single location aggregation Multi location aggregation Page 29
Proposal 3: Applicability Telemetry only: Option only for RIG aggregators representing multiple resources multiple single-location aggregations multi-location aggregations Not intended for individual direct telemetry connections RIG Aggregator Non-Spin, Spin, Regulation Single Resource Multiple resources Multiple Single-location aggregations Multi-location aggregation total >10 MW Telemetry Data Y N Y Y Y Page 30
Proposal 3: Subject Matter Panel Stakeholder Discussion Page 31
Proposal 4: Expand the ability for resources to submit Settlement Quality Meter Data Provides ability to develop lower cost methods to obtain and process meter data from distributed unit endpoints for resources that are multi-location aggregations Requires validation, estimation and editing (VEE) ISO maintains authority to develop set of metering equipment and accuracy requirements Quality assurance plan to ensure correct installation and meter accuracy is maintained. Leverages current application and SQMD submittal processes Page 32
Proposal 4: Applicability Metering Only Resources that are multi location aggregations with subresources less that.5 MW in capacity and less than 5 MWs in aggregated capacity Total capacity <5 MW & sub-resources <.5 MW Single-location aggregation Multi-location aggregation Metering N Y Page 33
Proposal 4: Subject Matter Panel Stakeholder Discussion Page 34
Proposal 5: Remove RIG Aggregator resource ownership and location limitations Enables aggregator to provide lower cost telemetry setup and services. Resource owners continue to remain responsible for providing direct telemetry data and maintaining its availability. Does not change telemetry and control response requirements set forth in ISO telemetry BPM Certification testing criteria including performance measurement are maintained Requires aggregator to execute an agreement, potentially an SC agreement Page 35
Proposal 5: Applicability Telemetry Only RIG aggregators representing single or multi-location aggregations. Current limit of 25 resources with maximum capacity of 400 MWs per RIG, including the ECN or ISP circuit and router, are maintained Page 36
