A Texas woman who was charged $9,546 for power this month has filed a class-action lawsuit against Griddy, alleging that the variable-rate electricity provider violated a state law against price gouging during disasters.

Lisa Khoury, a retiree in Mont Belvieu, signed up with Griddy in June 2019 and typically received monthly bills of $200 to $250 until this month's power disaster sent rates soaring. Griddy charged Khoury and her husband $9,546 from February 1 to 19, 2021, the lawsuit said, noting that "some customers received bills as high as $17,000."
