It really depends on your state. For some states, there’s little to no advantage by using another supplier. For other states you can reduce your costs by as much as 20%. The other factor depends on your energy consumption. For example, let’s say in your state you can only save about 5% using another supplier for natural gas. If your bills are $10k a month, why bother? If you bills are $50k or more a month it’s a different story.
