Three in every 10 Baltimore Gas and Electric Co. customers are buying their electricity through third-party suppliers, continuing a steady trend of increases in recent years, the company said Wednesday.
About 30 percent of electricity customers don't purchase their energy from BGE, up from 25 percent at the end of 2011 and 18 percent at the end of 2010, the company said.
BGE's natural-gas customers are less likely to switch to third-party providers, though more have done so in the last few years — 22 percent, up from 13 percent at the end of 2010.
Customers who switch to other energy suppliers pay those companies for their electricity or gas and BGE for the cost of delivery. Maryland's energy-market deregulation in 1999 made such a separation possible, but most customers haven't switched from the default choice for energy — BGE.
