The results of NYISO’s 2024 transitional cluster deliverability study show that more than $1.1 billion of high-voltage transmission upgrades would be required to accommodate 48 projects in the batch of generation projects.

NYISO’s Operating Committee approved the system upgrade facilities and system deliverability upgrade studies for Class Year 2023.

The NYISO OC has approved the class year 2021 study report; now generation developers must decide whether to accept or reject their cost allocations.

NYISO stakeholders voted to recommend the ISO’s Class Year 2021 study results and cost allocations advance to a vote by the Operating Committee.

About 40% of the proposed capacity seeking interconnection in NYISO’s class year 2021 is not deliverable without expensive upgrades, the ISO reported.
