Lesson learned from Europe. • Transmission System Operators – Higher reserves – Committed to zero Area Control Error – Strategic use of pump storage – Limited generation planned outages – Reduced high voltage direct current line capacities between the Nordic, United Kingdom and Continental Europe. – Activated emergency telecommunications, with back up – Specialized training for operators. – Raised awareness with market players and distribution system operators. • Germany – Procured 2 times normal regulations – Germany established special operational concepts for reserves • Italy – Reduce northern net transfer capability – Reduced day ahead PV production from 7 a.m. to 2 p.m. Slide 5 ISO Confidential
Potential mitigations to be studied by ISO: • Scheduling Coordinator engagement • Reserve procurement • Gas supply coordination • Flexi-Ramp usage • Special Operating Procedures • EIM transfer capability • WECC/Peak RC coordination • Hydro reserves Slide 6 ISO Confidential
