Utilization of the Remote Switch Applies only to 200 amp and below service (93% of our metered customers) Over 2 million service orders are requested per year DNP and Reconnect (52%) Move-in and Move-out (18%) During deployment, use of remote switch began as soon as the meter was provisioned (about 3 days after install) Orders that fail when using remote switch are retried for a period of time before being turned-down and sent to the field for execution by a line crew Real-Time monitoring and diagnostics of service order success is critical Measure and report actual performance Identify and resolve technology issues rapidly Digital meter Cell Relay Take Out Point Inform field management that service orders are coming their way 7

Error/Failure Analysis Turn downs are analyzed and categorized daily by type of order and by error category Typical error categories include: Request timed out communication delay or failure Possible tampering load side voltage detected on a disconnect (potential jumpers) No response communication failure Production monitoring alerts provide notice of issues to various levels of the organization Sophisticated retry logic is used before turning down orders to the field Digital meter Cell Relay Take Out Point 10
Example Daily Performance Report 9/4/2013 at 7:00am There were 21,695 orders for execution on Tuesday 9/3/13. 20,699 of them executed successfully through the MDM and 913 were successfully cancelled for a total 99.62 % success rate. 83 were turned down and sent to mobile. Successfully cancelled Retail Provider sent us a DNP cancellation or matching move-in following a move-out. 83 truck rolls were required compared to 20,699 that would have been required pre-ams
Benefits Over 2 million service orders are requested per year DNP and Reconnect Move-in and Move-out Off-cycle reads Electronic completion of service orders is faster Over 6 million to date Average time to execute was about 2 days, now < 30 min. Response to increased market expectations Service reconnects are now performed 7x24 (was 6x12) Faster recognition of potential tamper/diversion $24 million annual reduction in service order fees to customers Over 600,000 gallons of fuel saved Over 5,400 tons of CO 2 emissions avoided Reduced risk of employee driving or safety incidents Digital meter Cell Relay Take Out Point 12
