The California ISO Tariff requires the ISO to engage in a transparent and collaborative process while performing its 2019 and 2023 Local Capacity Technical Studies. As part of this collaborative process, the ISO and stakeholders agreed that the ISO will publish initial base cases on or about January 15, 2018. These initial 2019 base cases are now posted on the ISO Regional Transmission secure website at https://mpp.caiso.com/Pages/Default.aspx. The 2023 base cases will be available by the end of the day on January 26, 2018 at the same location.
Interested entities must complete, execute and submit the Regional Transmission Non Disclosure Agreement (NDA), and the Western Electricity Coordinating Council (WECC) Confidentiality Agreement to gain access to the secure website. These documents and other criteria for accessing the secure website are available on the ISO Transmission Planning webpage at http://www.caiso.com/planning/Pages/TransmissionPlanning/Default.aspx under the Accessing transmission data heading.
Entities may submit written comments on the base cases to regionaltransmission@caiso.com by close of business February 2, 2018.
The 2019 Local Capacity Requirements Final Study Manual is available at http://www.caiso.com/informed/Pages/StakeholderProcesses/LocalCapacityRequirementsProcess.aspx under the Studies and papers heading, 2019 and 2023 subheading.
