Review of Group Topics
Auxiliary Service – The parties will examine what rate class is most appropriate for customers that have a battery system installed behind the meter. The goal is to determine (1) if measurement of consumption and billing for customers with behind the meter storage should be unique; (2) if so, how; and, (3) if an auxiliary service tariff offering is necessary.
Interconnection Rules Evaluation – The parties will examine if a request to modify Commission interconnection rules is necessary to incorporate newly developed technologies such as, but not limited to, batteries and smart inverters.

As part of the Settlement Agreement, the Company commits to developing a study to identify possible interconnection points on the system via a red-light, green-light type of demarcation as described in the section of the Settlement Agreement for the RE Plan Section II.c. This stakeholder group will address the Company’s deliverables to effectuate this commitment.

III.C. Solar*Rewards Community / Grid Information for Interconnection
The Settling Parties recognize that understanding current distribution constraints on Public Service’s system could provide several benefits, including assisting CSG developers in siting CSG facilities. Public Service commits to developing a study to make available possible interconnection points on the system for CSGs via a red-light green-light type of demarcation. The details of such a study will be discussed further in the Distribution Grid and Interconnection Stakeholder group as noted in Attachment F. The Settling Parties agree that Public Service should receive deferred accounting treatment for the monies needed to complete this study. The study will be capped at a cost of $250,000 without further approval. The recovery methodology (e.g., through the RESA or base rates) of amounts included in this regulatory asset will be determined at the time the Company requests such recovery through rates.
