D.C. Councilwoman Yvette Alexander wants Pepco to explain its smart meters program after concerns from some residents that the meters might be violating their privacy.

Alexander, who represents D.C.’s Ward 7 and chairs the Public Services and Consumer Affairs Committee, said in a statement that she has received “numerous complaints from Pepco customers” and has asked the city’s Public Service Commission to “investigate any health, safety and privacy issues related to the installation of the smart meter.”
