Resource Integration Topics Jenifer Fernandes ERCOT Resource Integration Working Group October 24, 2024
Grid Interconnection Organization Updates Kenisha Webber: Large Gen Supervisor John Lawson: Small Gen Supervisor 2
RIOO Update ESR conversion Plan for collecting new ESR information, converting combo models, and final cleanup of data ESRs with PLDs on or prior to Sep. 2024 o Done - RFI information collected via DocuSign ESRs with PLDs of 10/2 and 11/1 o Modeling to send RFI template to directly to AR and BAR of ESR Completed spreadsheet should be submitted as an attachment-only RSCR o Convert to single model via script with RFI data. o Deadline to submit the RFI data in RIOO-RS is 12/2/2024. ESRs with PLDs of 12/4, 1/8, and 2/5 o Resource Integration to provide RFI template to RE. Completed spreadsheet should be submitted with the INR in RIOO-IS o After graduation, convert to single model via script with RFI data o Deadline to submit the RFI data in RIOO-IS is 12/2/2024. All in-flight ESR with 3/5 after or without PLD converted in RIOO-IS: o Within IS, run script to convert to single model o RE to provide all required data via RIOO panels Note: Providing good quality data is necessary to efficiently convert from Combo Model to Single Model. 3
Quarterly Stability Assessment (QSA) Planning Guide 5.3.5 Next Deadline for QSA All-Inclusive Generation Resource Initial Synchronization Date Upcoming January, February, March Last Day for an IE to meet prerequisites as listed in paragraph (4) below Prior August 1 Completion of Quarterly Stability Assessment End of October Prior November 1 End of January Upcoming April, May, June Prior February 1 End of April Upcoming July, August, September Prior May 1 End of July Upcoming October, November, December If a GINR is not included in QSA, its Initial Synchronization date will be automatically delayed to the next quarter 4
Quarterly Stability Assessment (QSA) Planning Guide 5.3.5, Quarterly Stability Assessment Issue s seen in previous QSA s 10 day comment period for FIS Needs to be complete before QSA deadline TSPs need to plan for it Dynamic/PSCAD Model Review Dependent on FIS Stability study Need to meet PG 6.9 15 to 30 days prior to QSA deadline PSSE Model Quality Test Required PSCAD Model Quality Test, Unit Model Validation and Template is required. PSCAD template is required starting August 1st QSA. TSAT Model Required If PSSE model is UDM, then TSAT model should be UDM and should include MQT 5
PGRR112: Feb 1,2025 QSA implementation FIS studies finalized and posted in RIOO-IS 45 days prior to quarterly stability assessment deadline. Dynamic models (PSEE, PSCAD, TSAT (UDM)) and MQT report submitted in RIOO-IS. From Planning guide Section 5.3.5 (2): Last Day for an IE to meet prerequisites as listed in paragraph (4) below Prior August 1 45 day deadline June 17 Prior November 1 September 17 Prior February 1 December 18 Prior May 1 March 17 6
PGRR088- Include Financial Security Amount in RIOO-IS RIOO-IS implementation 12/11/2024 Planning guide 5.2.8.1 (5): 5) Within ten Business Days of providing the TSP both the notice to proceed with construction of the interconnection for the Generation Resource and the financial security sufficient to fund the interconnection facilities pursuant to the SGIA, the IE must submit a change request via the online RIOO system to provide the financial security amount if it is not redacted in the public version of the SGIA filed with the Public Utility Commission of Texas (PUCT). ERCOT will include in the monthly Generator Interconnection Status report the name of the interconnecting TSP and the total amount of financial security sufficient to fund the interconnection facilities, if provided by the IE. 7
PGRR094: Requirement for Generator Construction Commencement or Completion Implemented in RIOO-IS. IE/RE can add submit or update the Construction Start and End Date via Change Request in RIOO-IS. Construction Start Date Enter (1) the date that physical on-site work of a significant nature (such as footing excavation or concrete pouring for foundations) has begun and is on-going, or (2) the date that major equipment items have been delivered to the site. Physical work of a significant nature does not include preliminary activities such as surveying, site clearing, test drilling and decommissioning of existing facilities. Construction End Date Enter the date when all plant systems are ready for commissioning/starting activities. 8
Commissioning Requests Submission- New Email Address ERCOT has established a new, dedicated email address for Market Participants to submit new generator Commissioning Checklist for review. Starting June 10, 2024, all new Commissioning Checklists (Parts 1-3) should be emailed to CommissioningRequests@ercot.com in addition to being submitted to RIOO-IS. Commissioning Checklists (Parts 1-3) submitted to ResourceIntegrationDepartment@ercot.com after June 21, 2024, will not be processed. Commissioning Plans should not be emailed for review to the new Commissioning Request email address. 9
Generation Interconnection Requests 1,881 active generation interconnection requests totaling 372 GW as of September 30th, 2024 (Solar 154 GW, Wind 35 GW, Gas 26 GW, and Battery 154 GW) (Excludes capacity associated with projects designated as Inactive per Planning Guide Section 5.7.6) 10
Generation Interconnection Requests Small Gen- 29 projects Not Model Ready, 48 projects Model Ready 11
