  2. Current Practices • Outage Planning g g – Share outage planning with NDA signed Gas Transmission Providers • Communications – Every two weeks phone calls with gas maintenance planners – Daily calls during peak demand periods D il ll d i k d d i d • What some of the issues are – Conflicting Peak Operating/Maintenance Seasons – Traditional rules in a new Renewable World Page 2

  3. Real Time Planning • What we are currently doing – Providing gas burn forecasts for Day Ahead and Day+1 EG P idi b f t f D Ah d d D +1 EG – Real-time notification if ISO dispatches high demand resources • Real Time Incidents – Coordinate with gas transmission providers to re-dispatch as needed to mitigate real-time gas supply issues. g g pp y • What are some of the issues – Short notice gas system maintenance that curtails a resource Sh t ti t i t th t t il – February 2014 • West wide natural gas availability issue Page 3

  4. Improved Gas Electric Coordination • By adapting current technology y p g gy – Visibility – Gas Electric Operational Zones – Improved Communication Improved Communication • EIM Update Page 4
