2024 adjustment of the emergency interconnection network upgrade maximum is posted

The California ISO published the 2024 adjustment to the emergency interconnection network upgrade maximum and the annual inflation factor. The current emergency interconnection network upgrade maximum is available on the generator interconnection request and study webpage under the heading participating transmission owner per unit costs.

The ISO and participating transmission owners may implement an emergency interconnection study process based on the strict criteria in the California ISO Tariff Appendix KK Section 3.10. These criteria help ensure parties do not use the Emergency Interconnection process except in the very narrow circumstances where it is necessary. They also help ensure emergency interconnections do not negatively impact any existing customer in queue. Criterion (d) requires any emergency interconnection’s network upgrades to be below $1 million as escalated annually.

The 2024 adjusted emergency interconnection network upgrade maximum will apply to any emergency interconnection study reports published from Sept.1, 2024 to Aug. 31, 2025.
