Frequently Asked Questions about Houston Energy Plans
Constellation is a retail electric provider in Houston that purchases electricity from producers (also known as generation companies) and sells it to customers. We’re an electric company in the sense that we sell retail electricity, but Constellation doesn’t generate power.
Power companies traditionally bill customers based on the amount of electricity used over a given time period. Such a process can make it difficult to estimate your energy costs from one month to the next. With a fixed-rate electricity plan from Constellation, you pay the same supply rate for the duration of your contract. Locking in energy rates can help you budget by protecting against periods of high demand, like a hot Houston summer, that could cause energy prices to go up.
No, it’s easy to switch electric companies. You won’t experience any service interruptions. In fact, the only thing you may notice is a lower energy bill!
Prior to competition, Houston residents had to purchase their electricity directly from the local utility, which was usually the only choice in town. Energy deregulation made it possible for Houstonians to buy power from a retail electric provider, which competes with other suppliers to offer the best electricity rates in Houston.
