Query the ISO-NE eData API for generator interconnection queue data and track DER aggregation milestones toward the November 2026 Order 2222 implementation deadline

Verified steps

1. Access the ISO-NE Generator Interconnection Queue via the ISO-NE public website; download the Interconnection Queue Report in Excel format from iso-ne.com/iqueue and parse for projects with technology type including 'Battery Storage' and 'Solar PV'
2. Filter for projects in 'Active' status and note the Queue Position Number, Capacity (MW Summer), Point of Interconnection, and Current Study Phase fields
3. For DER aggregation projects, verify eligibility under ISO-NE's Order 2222 Key Project implementation timeline: the energy and ancillary services markets implementation is scheduled for November 1, 2026; capacity market for February 1, 2027
4. Monitor the ISO-NE Order 2222 Key Project stakeholder page at iso-ne.com/committees/key-projects for tariff filings and implementation schedule updates; subscribe to the stakeholder mailing list for milestone notifications
5. For projects in the Interconnection System Impact Study phase, retrieve the associated study report from the ISO-NE document library using the project's Queue Position Number as a search key
6. Coordinate with the connecting transmission owner (CTO) on facilities agreements; ISO-NE requires the CTO to countersign the Interconnection Agreement before commercial operation can be authorized
