Self-Supply: Next Steps Carol Opatrny, for CECD NIPPC Board Meeting - 21 June 2010 Portland, Oregon
Self-Supply: Objective • Separately account for and provide Generation Imbalance Service using non-federal resources for specific resources (Iberdrola Renewables) located in the BPA Balancing Authority Area. • Meet 1-minute; 30-minute; and, 60-minute operating parameters that change monthly or more often. • Demonstrate that this arrangement does not “lean” on the federal system (cross zero requirement and timers). • Demonstrate adequate infrastructure, e.g., secure transmission rights, respect specified ramp rates; coordinate AGC; transfer information (ICCP); tag and update tags; satisfy reliability requirements (e.g., RAS, DSO 216); handle energy accounting.
Balancing Resources: Dynamic • Dynamic Transfer Capability • Most flexible and responsive • Quantity (MW) • Ramp rate (50 MW/minute) • BPA’s DTC Methodology • AGC system compatibility • 4 second signals • After-the-fact energy tag adjustment • Infrastructure • ICCP data exchange • AGC/EMS/Build specific logic for this arrangement • Energy Accounting
Balancing Resources: Static • Fixed, hourly transactions • Mid-hour transactions • Intra-hour schedule • On-Demand Rights • Firm Transmission Rights • No energy tag adjustment • Limited Infrastructure requirements • System modification by BPA to recognize ODR transactions among non-federal entities.
Balancing Resource Arrangements • Commercial terms between Buyer (IBR) and Seller • One-off Contracts/Terms Sheets • INCs • DECs • Versify Bid/Offer interface (available June 2010) • IBR Dispatch Model (drive dispatch priorities) • CECD (effects transactions; manages self-supply operations) • Transmission • Fixed (Intra-hour transactions; On-Demand Rights) • Dynamic Transfers • Infrastructure • Efforts underway to streamline the infrastructure requirements • Exploring how best to expand those involved
