Larger Project Implementation Issues and Integration of Storage

Larger Project Implementation Issues and Integration of Storage into the SIR October 24, 2017 IPWG Meeting 1

Larger Project Implementation Issues • Defining Project Requirements Necessary to Lock in Compensation – Can Projects above 2 MW apply prior to Commission Rule Change and be Eligible for the Value Stack? – What are the Project Requirements to Lock in Compensation? • 25% Payment and Given Utility Approval to Being Interconnection Design • Demonstration that Project is Obtaining All Required Construction Approvals 2

Aggregation of Smaller Projects • Are Existing Projects, 2 MW and Under, Allowed to Aggregate into Larger Projects? – If Allowed, at What Point in the Interconnection Process could this occur? – What would be the Project Requirements? • Same PCC for all Projects • Sequential in the Utility SIR Interconnection Queue on both the Circuit and Substation Bus • No other projects from NYISO or Non-SIR Utility Queues between projects that what to aggregate • Pay for any Additional Study and Upgrade Costs 3

Aggregation of Smaller Projects • How is Compensation Determined for these Aggregated Projects? – Do they loose their Tranche Position? – What Happens if the Projects are in Different Tranches? • What is Deemed to be a Material Change of a Project? – Do Material Changes Require a Developer to submit a New Application? – What Happens if Project has already paid 25% and been put in Tranche? 4

Integration of Solar Into the SIR • Should there be a limit of the Storage Nameplate Rating relative to the size of the DG System? • What are the metering requirements for paired systems? – Do metering requirements change based on the use case? – Are separate meters required for paired systems to verify how storage system is being charged? 5
