Pepco wants to raise electric bills for its Maryland customers by about $7 a month, as well as tack on a surcharge to pay for improvements to its electric grid.

Pepco expects the $60.8 million rate increase to add $7.13 — 4.98 percent — to the typical resident’s monthly bill beginning in July 2013. The surcharge, meanwhile, would be another 96 cents per month — 0.64 percent — starting in January 2014 and increasing for each of the next two years up to $1.93 per month in 2016. In total, the surcharge would raise roughly $45.9 million.
