Generator interconnection procedures cluster 1 and 2 deliverability concerns
A number of stakeholders have raised concerns that the long development timelines and high costs of network upgrades in adjacent PTO service territories identified for certain Cluster 1 and 2 generation interconnection projects will impede the commercial viability of these projects. The identified need for these upgrades is related to the high volume of generation that was included in the Cluster 1 and 2 phase 2 studies.
The ISO posted the below technical bulletin that describes the ISO methodology for identifying required delivery network upgrades for generation projects in interconnection queue clusters 1-4. The bulletin also clarifies some important points on the ISO determination of generation projects’ annual net qualifying capacities.
