Energy Exchange - Results

• 231 customers representing 338 accounts
• Potential curtailable load of 475 MW
• 169 accounts (50) have only identified the
  minimum 200 kW as their curtailable load
• During 2001 the maximum load curtailed during any
  one event was approximately 60 MW.
• Between December 2000 and September, 2001 the
  program generated 136,217 MWh of curtailment.

Energy Exchange Lessons

• Results were favorable when market prices were
  high
• Price elasticity is evident
• Customer gaming must be monitored
• Customer education important
• Real-time data would improve results
• Reconciliation of curtailed load is complex
• Expanding pledge options beyond one or two days
  ahead improves results
• Customer input key to enhancing program
• Customer participation in a curtailment event is
  not automatic - operational considerations
