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

• f affordable, reliable capacity needed

Supply Challenges are coming. How is natural gas preparing to serve?

Natural gas service for power generators has continued to evolve

Operational Transparency

• Increased transparency and communication re: system
• perations
• Operational knowledge (T2 yellow light)

Non obligated deliveries

• Only supply gas when generating electricity

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
