Needs – Natural G Gas What Generators t told U Us “Power Services” Response How did the Natural Gas • T2 (Union S South) Industry • F24T & F24S (Union S More frequent nomination S&T) position for windows or “firm all day” • FTSN (TCPL) “off coal” • Rate 1 125 (Enbridge) • High D Deliverability S Storage Access to firm high levels of deliverability (Union & Enbridge) • Upstream P m Pipeline Load shaping – (non uniform Balancing Service ( Union) deliveries to plant) • Downstream m Pipeline Ability for plant to change Balancing Service (Union) flows on very short notice Natural Gas I Industry responded to Generators need for services to allow them to be flexible and responsive t to the short notice generation world 6
Supply Challenges are coming. How is natural gas preparing to serve ? Shortfall begins in 20 2023 23 2, 2,00 000 0 MW o of affordable, reliable capacity needed 7
Operational Transparency Natural gas service for • Increased transparency and communication re: system operations power Operational knowledge (T2 yellow light) • generators has Non obligated deliveries continued to Only supply gas when generating electricity • evolve Parkway deliveries transitioned t to D Dawn (PDO) Greater liquidity and lower prices at Dawn for gas supply • • Lowers costs for all Ontario consumers “Firm” Dawn Vector Balancing Service • Firming up intra hour balancing services west of Dawn Natural Gas i is c commi mmitted to s serve Ontario Power Generation 8
