Conowingo Power Co. customers will see an average 35-cent increase in their monthly electricity bills due to company rate changes that took effect Feb. 1.
Conowingo serves about 4,000 customers in northeastern Harford County and 29,000 customers in Cecil County. The company hasn't increased its rates since 1986.
The rate increase means that the typical residential customer using 500 kilowatt-hours of electricity in a month will pay $53.19, up from the 1991 average bill of $52.84, the company says.
John Denver, a Conowingo spokesman, says the company's rates are "just a little bit higher" than those charged by Baltimore Gas and Electric Co., which serves most of central Maryland. BG&E; customers pay about $52 a month for using 500 kilowatt-hours of electricity, he says.
The new Conowingo rates are part of a 27.7 percent, $15.7 million increase that was approved by the state Public Service Commission last month. The company is phasing in the increase over 10 years to limit the impact on its customers, Mr. Denver says.
For 1992, Conowingo will boost electricity bills by an average of 6.9 percent, according to the plan.
