OGE Energy Corp implemented a smart grid program between 2010-2012 that included installing smart meters for nearly 800,000 customers, deploying demand response programs, and enabling remote disconnects and reconnects. The program goals were to reduce operational costs, engage customers, avoid building new power plants, and improve reliability. OGE customized their SAP system to support meter deployment, dynamic pricing, demand response programs, and remote service provisioning through the smart grid infrastructure.

10. • February 15, 2010 –
First meter set in Norman, OK
• 200 per day at first
• Ramped up to around 2000+ per
day over a 3 year period
• Meter Deployment officially
ended in December of 2012
Meter Deployment
By the Numbers

2012 299,000 meters

12. • Weekly Meter Deployment population file
o Population file used by meter installation vendor to plan and schedule meter deployment
• Black Out Window (Dunning disconnects and billing)
• SAP Serialization program to consume meter vendor data
• Automated meter installation program written to install meter in SAP
• Sync program to MDMS system
• Based upon what meters were installed per day, SAP generated Location
Information File which would sync with AMI system
SAP Development to Support Deployment
Slide 12

13. • Once smart meter installed, no meter reader used
• Custom programs created to satisfy meter reading document for billing
• Normal register reads
• Demand response using daily register reads
• Calling MDMS using interval data for demand response
• Interval meter data used for complex tariffs
• Goal - no estimation to generate electric bill
• Meter Deployment plan allowed us to read and bill customers with no
interruption to billing schedule

23. • Leave existing disconnect processes in place
o Existing processes included Business Workflows and programs to generate PM
orders to reconnect/disconnect service
o Programs running to look at device category to determine if the order should be
sent to the field or queued in SAP to provision remotely
• Additional considerations for Dunning
• Additional considerations for Vacancy Reconnect/Disconnect
