Constellation - You have the Power To Choose Your Energy Company
Energy deregulation in Texas refers to the separation of the generation and retail sale of electricity from the transmission and distribution of electricity, which allows consumers to choose their electricity provider from a variety of options. The process was implemented in 2002 through legislation, leading to increased competition and potentially lower prices for consumers. However, it also created some challenges such as lack of oversight and market manipulation.
SlashPlan is a service that can help consumers navigate through the options and make an informed decision when choosing an energy plan. It compares plans from different providers and identifies the cheapest options available.
By using SlashPlan, Texas residents can easily save time and money on their electricity service. The service takes into account all hidden fees that providers may charge and provides a true apples-to-apples comparison, making it a user-friendly and efficient way to find the best deal on their electricity service.

Constellation FAQ
How long does it take to start service?
Service can typically start either on the same day or the next business day after you sign up for it.
Do you have cancellation fees?
Cancellation fees vary depending on your plan and length of service. Please refer to the EFL document to determine if any early termination fees apply.
If you move to a new house, the cancellation fees will be waived.
What is a fixed rate plan?
Traditionally, power companies bill customers based on the amount of electricity used over a certain period of time, which can make it hard to predict energy costs from one month to the next. However, with a fixed-rate electricity plan from Constellation, customers pay the same supply rate for the entire duration of their contract. This can aid budgeting by shielding against spikes in demand, such as during a hot Houston summer, which can cause energy prices to increase.
What is the cheapest plan Constellation offers?
Constellation offers a range of energy plans to choose from. To select the most cost-effective plan, you need to consider your home's monthly energy consumption measured in kilowatt-hours (kWh).
