The California ISO has scheduled a public stakeholder call for May 2, 2019 to discuss the issue paper and the ISO cost responsibility for breaker replacements at McCullough and Marketplace. The ISO held two stakeholder events in November and December 2018 to propose revisions to the generation deliverability assessment methodology. Stakeholder’s written comments were generally supportive of the proposed changes, but raised various concerns regarding impacts to other processes and existing generation, and recommended that the ISO take more time to address these concerns. In response to these comments, the ISO has drafted an issue paper that builds on the stakeholder discussion that started in 2018 within the 2018-2019 Transmission Planning Process.
In addition, transmission projects previously approved by the ISO and generation projects requesting to interconnect are expected to adversely impact the short circuit duty at Los Angeles Department of Water and Power’s McCullough and Marketplace substations. As a result, the ISO will be responsible for circuit breaker replacement costs at those substations. The ISO will discuss the McCullough and Marketplace circuit breaker replacements and the cost responsibilities during this call.
The generation deliverability assessment issue paper is available on the initiative webpage at http://www.caiso.com/informed/Pages/StakeholderProcesses/GenerationDeliverabilityAssessment.aspx. A presentation will be available prior to the meeting on the webpage linked above. In addition, the McCullough and Marketplace breaker replacements presentation will be available prior to the meeting on the 2019-2020 Transmission Planning Process webpage at http://www.caiso.com/planning/Pages/TransmissionPlanning/2019-2020TransmissionPlanningProcess.aspx.
Please submit written comments on the issue paper and on the circuit breaker replacements to regionaltransmission@caiso.com by end of day May 16.
