Pepco to Not Provide Residential AMI Data to Retail Suppliers on Daily Basis

Pepco has informed retail suppliers in the District of Columbia that, at this time, it does not intend to provide, on a daily basis, residential interval data from advanced meters to retail suppliers.

In a post-technical conference report regarding various retail supplier AMI issues, Pepco noted that it was asked whether Pepco would provide the AMI consumption data the day after it was used (i.e., daily data).

At this time, Pepco provides interval data the day after for commercial customers and industrial customers who are processed through the MV90 system via a secured website.

"Pepco does not intend to place residential AMI interval data on this website given the Company's substantial investment in EDI, which provides information on a monthly basis," Pepco said.

"Furthermore, Pepco employs data quality measures, including validation of metered data. For example, any meter data found missing for Interval Billed Accounts would need to use estimates from Pepco's Meter Data Management system based on established estimation criteria. Any bill with an estimation not based on an actual register reading will be considered estimated and will be reviewed before sending to the customer. If revised data determined to be accurate is received after estimated or edited data has been sent to billing, the system will automatically send additional data to the billing system. The billing system will then automatically generate a 'cancel and rebill' to the account (and TPS) or be placed in a work queue to be further evaluated. These circumstances tend to be rare, but billing-quality data requires time to review for possible errors."

Once AMI is fully implemented (customers are billed using intervals), Pepco said that suppliers will be able to choose which format they prefer to receive from AMI interval meters through EDI, either the 867MU or 867IU. AMI interval metered data will be provided once per month based on a customer's billing cycle. "This process ensures that the data is properly validated and will provide bill-quality data," Pepco said.
