Oklahoma Gas and Electric APSC Workshop on Electricity Demand Response and Advanced Metering for Integrated Utilities Demand Response & Automated Metering Infrastructure Now and into the Future Philip R Bartholomew Oklahoma Gas and Electric May 24, 2007

Current Programs Demand Response Programs Load Curtailment Interruptible Rider Performance Award for Curtailed Energy (PACE) Automated Metering Infrastructure Billing Customer Information Systems Inter-connection Monitoring

Load Curtailment and Interruptible Similarities –Customer signs a contract to limit use during events –Customer paid a reservation credit each month –Events limited to: Between 4 and 8 hrs / event No more than 100 hrs per year Differences –Interruptible customers MUST curtail –Curtailment Customers can choose Perform Don’t Perform (penalties apply) Buy-through (Real-time Pricing Customers only)

Performance Award for Curtailed Energy (PACE) Customer applies for rate –250 kW billing demand demonstrated No contract No minimum reduction No requirement to perform No reservation fee Paid on per event basis –Cents / kWh avoid –10% minimum threshold (by formula)

Automated Metering Infrastructure (Remote Access to a Meter) Billing –Remote areas –Special Cycles Interconnects –To other load serving entities –Jurisdiction Metering for COS Customer Information Services –RateTamer –Customer’s load management system

“The Future” Meters are evolving (AMR) –IP addressable –Lower Cost –More pathways to get to meter built in Communications is Evolving (AMI) –Broadband over Powerline (BPL) –Wi-max, dark fiber, 900 MHz Software approaching end-of-life (MDM) –Can’t handle all the data –Can’t initiate advanced activities (cut-offs)
