Energy provider comparison criteria

Comparing plan types: Constellation Energy vs Chariot Energy

In the Texas electricity market, you can find a wide variety of plan types, including the following:

  • Fixed Rate: Fixed rate plans lock in an energy charge for the duration of your contract.
  • Variable Rate: The energy charge is subject to change each month based on changes to wholesale electricity prices.
  • Solar Buyback: Plans that allow you to sell energy back to the grid from solar panels installed on your property.
  • Bill Credit: A common electricity plan gimmick that disguises high energy charges with a bill credit.
  • Time-of-Use: Time-of-use plans offer different energy charges based on the time of day or day of the week. The most common are “free nights” and “free weekends” — watch out for these gimmicky plans because free electricity at night or on the weekend often means much higher energy charges during the day or during the week.
  • Base Charge: Plans that include monthly base charges. An extra fee added to your bill no matter how much electricity you consume.
  • Usage Fee: Plans that include usage fees. These extra costs are added to bills when you use the “wrong” amount of energy during a billing period.

Monthly energy usage charges

Usage fees are extra costs added to bills when kWh consumption is either “too high” or “too low” during a billing period. In the case of a minimum usage fee, if you use less than the specified kWh amount, an electricity provider may tack another fee onto your bill. It’s generally recommended to avoid electricity plans that charge usage fees.

ProviderUsage fees
Constellation EnergyNo usage fees
Chariot EnergyNo usage fees
BKV EnergyNo usage fees
*Table last updated March 17th, 2025.

What are base fees on your electricity bill?

Base charges are extra costs added to every bill, regardless of how much electricity is used during that billing period. We recommend finding a provider and a plan that does not include base charges in the contract.

ProviderBase charges
Constellation EnergyNo base charges
Chariot Energy$9.95
BKV EnergyNo base charges
*Table last updated March 17th, 2025.

What are the penalties for ending your contract early?

Early termination fees (or early cancellation fees) may be charged when you decide to cancel a plan before the end of the contract. Texas electricity providers typically charge ETFs in one of two ways. First, some providers will charge a flat cancellation fee that remains the same no matter how far you are into your contract. Second, other providers, like BKV Energy, will charge a cancellation fee that decreases the longer you remain a customer. This often makes switching providers less costly if you switch to a different provider early.

ProviderEarly Termination Fees
Constellation EnergyRanges from $50 to $150 depending on contract length
Chariot Energy$15 per remaining month
BKV Energy$20 per remaining month

Affordable plans available, which is very helpful in the DFW area, also they are a company that values their customers and incentives them for their loyalty and makes sure they are taken care of! I’ve had a great year using the company, and just renewed for another 12 months of service with them!

Just been with BKV Energy for one month. Switch from last provider was seamless. BKV Energy website was intuitive, easy navigation. AutoPay occurred on “Due Date”. I would like to see an option for me to be able to set the auto pay to happen sooner after the invoice date, soon after I review the bill. I was with my last provider for 25 years. I hope BKV can provide me the best rates for the next 25 years.
