I switched from ComEd about 6 months ago. During the winter months my bills were about $10 lower than with ComEd. As soon as it got a little warm, my bill doubled. My bills in August of last year with ComEd at the height my electric use were not as high as Energy Plus. It is clear that they will charge you low prices during the winter and double your bills as soon as the summer months come. If I stay with them through the summer my bills will be at least twice the cost of ComEd bills last month based on the prices and usage charts on my bill. It takes 2-3 months before you can switch back to ComEd so they can keep charging you outrageous bills for 2-3 months more when you are using the most energy. DO NOT SWITCH TO ENERGY PLUS HOLDINGS!!!
