FAQs 6

What are CAISO's interconnection reforms?

The interconnection reforms are part of an agreement among CAISO, the PUC and the California Energy Commission that aims to better coordinate resource and transmission planning, interconnection processes and resource procurement. CAISO is working with stakeholders on additional reforms to its interconnection rules.

How many GW of interconnection requests does CAISO have?

CAISO has over 500 GW of interconnection requests, “10 times more than its roughly 50 GW peak load,” which has kept its focus on reducing the queue, said LBNL Energy and Environmental Policy Research Scientist and Engineer Will Gorman.

Is CAISO's interconnecting process a major obstacle to California's decarbonization?

Although CAISO has opened the door for one of the world's largest operating clean energy portfolios, its process for interconnecting new projects has become unwieldy, obsolete and a major obstacle to California's decarbonization, according to participating transmission owners and power plant developers.

How many GW does CAISO have in its interconnection queue?

When CAISO started its interconnection reform stakeholder process in May 2023, the grid operator had 185 GW in its active interconnection queue, it said in its FERC application. It has another 347 GW from “Cluster 15,” its most recent annual interconnection window, which is on hold.

What is CAISO doing with FERC?

CAISO is working with stakeholders on additional reforms to its interconnection rules. Also, FERC is reviewing the grid operator’s plan for complying with the agency’s Order 2023, which set requirements for generator interconnection processes across the United States.

How many GW does CAISO have?

It has another 347 GW from “Cluster 15,” its most recent annual interconnection window, which is on hold. Under CAISO’s approved proposal, the grid operator will determine what zones in the state have available transmission capacity to handle new interconnections.
