You get BGE merger credit even if you switched
As noted, Constellation, Exelon and the governor have agreed on a settlement in which, among many other items, BGE customers get a $100 credit on their bills. ALL BGE customers. Readers often worry that if they have switched to Veridian, Ambit, Washington Gas Energy or some other alternative electricity provider, they won't get this kind of rebate.
Don't worry. Everybody gets the credit no matter who their electric supplier is. The credit is funneled through the BGE part of your bill, not the electric supply part. BGE is always your electric delivery company no matter whom you buy your electric supply from. So all 1.1 million BGE customers get the $100, even if they shop around and buy something other than BGE's default electricity product.
