EPRI Demand Response Pilot

• Price based Load Management
• Hybrid of TOU / Real-time pricing
• High fixed price for predetermined number of
  hours (i.e., 300 hours/year)
• Hours called day-ahead when peak events occur
  (hot-spells, cold-snaps)

EPRI Demand Response PilotPotential Benefits

• Predictable payback on customers investment to
  reduce peak
• More closely targeted, higher incentive than
  traditional TOU
• Less customer risk than market-based rates
• Good during volatile spot market, high rates of
  capacity expansion

14
EPRI Demand Response PilotOperational Strategy

• 2-way communication system for day-ahead
  notice/alert messaging
• Equip each building with gateway linked to
  building control systems
• Customers program their systems for automated
  response (with event override option)

15
EPRI Demand Response PilotPilot Project Goals

• Can both customer and utility benefit
  financially?
• Will customers accept the challenge?
• Is a significant customer response feasible?
• What kind of load management options make sense?

16
EPRI Demand Response PilotPreliminary Study
Results

• Peak shaving (conservation on peak) limited but
  shows good payback
• Load shifting (I.e., thermal storage) less
  promising
• Use of customer generation has significant load
  reduction potential
• Project currently On Hold
