The California ISO will hold a stakeholder call on April 11, 2019, to discuss the Phase 3 Transmission Planning Process for the Gates and Round Mountain 500kV Dynamic Reactive Support Competitive Solicitation projects. The ISO identified these Dynamic Reactive Support solutions through the 2018-2019 transmission planning process, which was approved by the ISO Board of Governors on March 27, 2019.

The webinar will cover the following topics:

  • Project functional specifications and key selection factors
  • Submission of project sponsor applications
  • Competitive solicitation process steps and schedule
  • Matrix log of questions and answers
