2019 Annual Plan Item 2a Posting of additional curtailment information on OASIS (Joint BPS/OASIS) 3/26/2019

API 2a FERC Initiated in Order 890 P. 1627 We agree with suggestions for the posting of additional curtailment information on OASIS and, therefore, require transmission providers, working through NAESB, to develop a detailed template for the posting of additional information on OASIS regarding firm transmission curtailments. Transmission providers need not implement this new OASIS functionality and any related business practices until NAESB develops appropriate standards. These postings must include all circumstances and events contributing to the need for a firm service curtailment, specific services and customers curtailed (including the transmission provider’s own retail loads), and the duration of the curtailment. 3/26/2019

API 2a Posting of Curtailment Information Focus on interconnection-wide curtailments (e.g., IDC for the Eastern Interconnection, ECC for WECC) Whenever scheduled transactions are impacted on the TP’s system, the TP must ensure that all actions issued under the procedure are provided, even if they are on other systems. Subcommittees have drafted business practice standards Standards require RC to provide requisite information for the OASIS posting. Draft is out for informal comments – due 3/18/19 3/26/2019

API 2a Current Work Effort BPS/OS Challenges on 2019 API 2a No current commitment from EI (EIDSN) Western RC is in flux (CAISO, SPP, et al) Western RC function expected to stand up by end of 2019 Question on timing of submitting recommendation Finish standard language and submit knowing that Transmission Providers may not be able to post data and data formats may not align with the RC data Finish coordination with EI and WECC RCs prior to submitting standards 3/26/2019
