DTE rates changing depending on the time of day; here's what that means

More than 2 million DTE Energy customers are about to see their rates change to a "time of day" rate. It's part of an effort to lower peaks in demand, and help customers manage their energy use. The rate rolls out in March, and your energy use in off-peak hours will cost you less than what the base rate is now. But, electricity during peak hours in the summertime will cost you more. “Why was this rate change needed?" I asked DTE's Chief Customer Officer Angie Pizzuti. "So, the rate change is really about giving customers choice and the ability to shift and save some of their usage in order to take advantage of lower rates," she said.
