The price boost - even if it is short-lived - is likely to trigger renewed interest in shopping for electricity suppliers.
"The smart Peco customer would be shopping," said Engel Menendez.
Since January 2011, about 474,000 Peco customers have switched to alternative suppliers under the state's electric choice system.
The Pennsylvania Public Utility Commission has posted offers for Peco customers from 45 residential suppliers on its website, PA Power Switch - Pennsylvania Public Utility Commission
. The offers include fixed-rate, variable rate and green-power options.
Some suppliers are offering fixed-rate deals as low as 7.6 cents per kWh, or nearly 28 percent off Peco's price.
"For bargain-basement customers, these are the lowest prices I've ever seen," said John Raisch, a cofounder of Alphabuyer.com, a Paoli group-buyer that is offering a six-month fixed rate of 7.55 cents per kWh.
Under the PUC's rules, distribution companies like Peco are considered the supplier of last resort, and can only offer a single "default" rate for residential customers. Peco was required to phase out discounted rates for electric heating customers, as well as a cheaper off-peak rate for customers with electric water heaters
The PUC website has several offers posted for RH customers, as does the Pennsylvania Office of Consumer Advocate: Pennsylvania Office of Consumer Advocate
