CHICAGO (WLS) — There’s a new warning from the Illinois attorney general concerning the new smart meters, and people who may use the technology to take advantage of you. If you don’t have one already you will soon; ComEd says it has installed about 2 million smart meters. But the I-Team found that some businesses could use the new meters to sell you a questionable plan. It’s out with old analog meters and in with new digital ones. You can use them to save money by tracking your real time electricity use. But with the technology, comes a warning. “So there is a lot of potential for consumers to be deceived and ultimately spend more money,” Illinois Attorney General Lisa Madigan said. Madigan says unregulated, alternative energy suppliers will soon be asking for authorization to to read smart meters, so they can sell customized electric plans based on user habits. Some of those plans could save you money but it also opens the door for potential bad deals. “They may come to your home, they may call you on the phone, maybe they will send you something in the mail asking you to sign that authorization,” Madigan said.
