Our response to COVID-19
We’ve made some changes due to COVID-19, including suspending service disconnections for residential and small business customers for nonpayment, and only continuing critical work needed to protect public safety and reduce the risk of wildfires. Learn more here. If you have recently lost your job, even if you are receiving unemployment benefits, you may qualify for a reduced energy rate through our CARE or FERA programs.

Meter Data Management

Simply put, Meter Data Management consists of processing the data on a customer’s meter. This is done by a qualified Meter Data Management Agent (MDMA) who reads meters, validates meter data, and estimates missing data to be used in various applications as defined by the California Public Utilities Commission (CPUC).


MDMAs are responsible for collecting customer usage data, and ensuring the data is correct. Once the data has been validated, the MDMA passes the data through Electronic Data Interchange (EDI) to post to the MDMA server. This data is presented to the customer as a bill by the contracted Electric Service Provider (ESP).  

If the MDMA is unable to collect data, or if the data proves faulty, the MDMA will estimate customer usage based on usage history.

Types Of Technologies

A qualified MDMA may collect raw meter data using any of the following meter reading technologies:

  • Physical on-site meter probing process
  • Modem technology, a dedicated telephone line-connected remote interface
  • Radio technology
  • Pager technology
