Not at all. Utilities in deregulated markets do not make a profit on the supply of your electric or natural gas. They make their money from billing and delivering the electric and gas through the infrastructure that they have in place. As a matter of fact, many Utilities have incentives for customers to switch to a Third Party Supplier by giving a percentage of the first two months of your bill, while some states or cities give tax breaks in certain utilities for switching to another supplier. These are only in limited areas, such as Coned in NY for example as well as LIPA in Long Island.
