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 D il ll d i k d d i d – Daily calls during peak demand periods

• What some of the issues are

– Conflicting Peak Operating/Maintenance Seasons – Traditional rules in a new Renewable World

Real Time Planning

• What we are currently doing

P idi b f t f D Ah d d D +1 EG – Providing gas burn forecasts for Day Ahead and Day+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

Sh t ti t i t th t t il – Short notice gas system maintenance that curtails a resource – February 2014

• West wide natural gas availability issue
