CRR Technology Update Sreenivas Badri December 06, 2024
Current State CRR High Level Architecture Hardware changes implemented early this year (April) o Increased CRR Engine Servers (Virtual Machines VMs) CPUs to 28 from 16. o Tuned Hardware Parameters o CRR performance improved by around 20% due to hardware changes Why can t we add more CPUs or more VMs to improve the CRR auction performance? o Adding more CPUs beyond 28 did not improve the CRR performance further due to saturation of CPU/RAM bus with current hardware configuration (DDR4 Memory configuration). o CRR Engine supports multi threading but due to the sequential and interlinked nature of budget constraints across all months in a long-term auction, using multiple VMs or servers for parallel processing is not viable. 2 PUBLIC
Testing CRR Performance with New Hardware Configurations POC On-Prem Work In Progress Built a Sandbox Environment with new hardware configuration DDR5 Memory Faster Memory access with DDR5 hardware configuration CRR system is being built, performance testing will start next week Plan to complete the performance testing by early January Expecting approximate 30% performance enhancement. POC In Cloud - Planned Vendor supports CRR applications running in Cloud Test CRR performance in cloud environment utilizing other advanced hardware configurations. Plan to complete the testing by end of Q1 2025. Evaluate CRR performance improvements from POCs and plan for next steps. 3 PUBLIC
CRR Technology Road Map Project ERCOT Cloud Foundations Initiated Establishes robust Cloud Foundation and connections ensuring secure, compliant, and optimized cloud services Expected to complete by Q2 2025 Project CRR Tech Refresh Tentatively scheduled to start Q1 2026 Key drivers: Upgrading Oracle DB and Operating system, 3rd party software Containerize CRR Apps (On-Prem) Will look at options to run CRR long term auctions only in Cloud with more advanced hardware configurations to enhance CRR auctions performance. 4 PUBLIC
