In addition, no information of a secret or proprietary nature shall be made available to stakeholder engagement members. All proprietary information which may nonetheless be publicly disclosed by any participant during any stakeholder engagement meeting or its subgroups shall be deemed to have been disclosed on a non-confidential basis, without any restrictions on use by anyone, except that no valid copyright or patent right shall be deemed to have been waived by such disclosure.

Draft for Discussion Purposes Only 4 Overall Engagement Group Purpose & Objectives Purpose The Market Operations Stakeholder Engagement Group (EG) is an open forum for stakeholders who are actively engaged in the REV process and the Distributed System Implementation Plan (DSIP) filings to provide input to, and exchange ideas with, the Joint Utilities of New York (JU) on topics related to grid operations as identified by the Joint Utilities Stakeholder Advisory Group (AG). Objectives The AG will advise the JU on the sequence and priorities of topics that Engagement Groups should discuss. The AG will also provide input on Engagement Group members, discussion scope, and any output documents that would advance greater shared understanding. The Engagement Groups will hold discussions on identified topics in order to achieve greater shared understanding of issues covered in the DSIP filings, and to build toward common ground through iterative discussion and feedback.

Draft for Discussion Purposes Only 6 Customer Data Topic Description Customer Data may identify the person or entity to which it applies Customer information may include usage data, account/profile data, end-use and other qualitative data, and results from customer-specific analyses Customer usage data is a subset of customer information and contains a customer's usage or production of energy o The Commission’s REV Track 2 Order defined Basic Data as "the usage for each applicable rate element, including usage bands specified in the applicable tariff. This is the level of data necessary to render, reconstruct and understand the customer's bill" o Usage data can be shared with authorized third parties, or aggregated by various groupings for use by third parties

Draft for Discussion Purposes Only 7 Customer Data Engagement Group Charter Purpose: Explore the Joint Utilities' approaches for facilitating market mechanisms that effectively support and encourage the adoption of Distributed Energy Resources while meeting customers’ needs and complying with the DSIP Guidance Order Topics and Scope: Customer Data Customer Data Data Collection, Reporting Frequency and Availability of Usage Data o Discuss how often usage data might be collected by the utility, how often it would be made available to customers/authorized agents, and at what quality level o Discuss customer data platform-related sensitivities (e.g. AMI versus non-AMI systems) Aggregation of Usage Data o Discuss standardized aggregated data offerings (e.g. kW and kWh by rate class, tax district, zip code) o Discuss utility-sided aggregated data system automation efforts and reporting methods o Discuss standards for anonymizing aggregated data to protect individual customer privacy (e.g. 15/15 rule) Additional Data Needs o Explore and identify additional useful customer information beyond usage data o Note: pricing for Basic and Value-Added data is a Track 2 matter

The Joint Utilities support providing customer usage data to both customers and authorized third parties as a means of facilitating DER adoption Basic Data Value-Added Data All utilities plan to provide customer usage data via some combination of the utility bill, Green Button Download/Connect, EDI, and the utility's online customer engagement platform(s)
