  CAISO posts Large Loads Initiative draft final proposal and tariff language for comment (Large Loads Initiative)

  Source: California ISO · Sep 24, 2026

  CAISO says its Large Loads Initiative draft final proposal and draft tariff language would add rules for large loads, including “Procedures to improve large load information visibility,” a “Framework to prevent cost-shifting,” and a “Framework for a flexible interim load interconnection (FILI) service to expedite interconnection.” CAISO also says the proposal adds detail on “operational requirements for the FILI framework” and “interactions between load interconnection studies and the transmission planning process,” while deferring a permanent flexible load interconnection option to future stakeholder processes.

  Large Loads Initiative: Additional discussion of operational and technical requirements, call on 8/24/26

  Source: California ISO · Aug 17, 2026

  California ISO said it scheduled an additional stakeholder meeting for the Large Loads Initiative “to provide additional time, if needed, to discuss the operational and technical requirements” in the Large Loads Straw Proposal and Large Loads Technical Requirements Straw Proposal, with topics including “Operational requirements” and “Technical requirements” (California ISO, Aug. 17, 2026). The notice also says the Aug. 24 meeting was contingent and ultimately unnecessary because “We were able to cover all of the material and will no longer need the meeting on 8/24.”
