Baltimore Gas and Electric advises customers seeking to defer the installation of smart meters in their homes to make a request in writing.
Customers should address mail to Smart Meter Deferral, BGE, P.O. Box 1475, Baltimore, MD 21203.
In the letter, BGE said, customers should include their name, address, account number, phone number and email address.
Last week, the Maryland Public Service Commission issued an interim ruling allowing utility customers to defer installation of the new digital, wireless devices until regulators make a final decision on whether ratepayers can opt out.
The state's three largest utilities — Baltimore Gas and Electric, Pepco and Delmarva — are in varying stages of replacing older meters with smart meters, which are intended to provide real-time data and help ratepayers monitor and control energy consumption.
BGE began installing smart meters this month. The switch-over to the new meters is expected to take until the end of 2014.
