National Grid upgraded most of its meters in the Buffalo Niagara region several years ago.
The upgraded meters also could be a tool to help consumers conserve energy if customers used time-based rates that charge higher prices when the demand for electricity is highest and lower prices when demand is low, such as during the early morning hours.
NYSEG, in a filing with the state Public Service Commission, has proposed paying for the $243 million meter upgrade program through a surcharge on customer bills.
