Shopping for lower electricity prices in Pennsylvania can lead to substantial savings with the end of rate caps and numerous companies have emerged to serve that market. But The Watchdog notes that customers should always be careful in how they go about shopping for electricity providers.

A couple in Copley, Pennsylvania, received a visit from a door-to-door salesman from alternate electricity supplier Respond Power, with confusing information about a rebate program being run through Pennsylvania utility company PPL.

When The Watchdog called Respond Power, the company's director of marketing and customer service, Mark Berger, explained that the program the salesman at least should have been talking about was Respond Power Rewards, which offers customers the change at a rebate by reducing usage when electricity rates are high.

While sometimes customers simply misunderstand salespeople who are talking about an unfamiliar topic, Berger noted some also feel like they can see higher sales with an unscripted sales pitch.

The Watchdog notes that customers can find lower electricity rates by shopping around, but it makes more sense to make use of the all available resources, rather than deciding on the spot with a door-to-door salesperson.

The state offers some information on electricity deregulation and the benefits for residents and the state on its site, PAPowerSwitch. So far the site notes that more than 1.2 million Pennsylvania residents have chosen to switch electricity rates.
