At Home Energy Club we gather customer opinions and reviews from independent review sites, the State of Texas Public Utility Commission Complaints Statistics, and other review sources.

Visit our electric company reviews pages to compare reviews side by side.
Constellation Rates & Plans
Constellation Energy offers Texas electricity with a range of energy rates and contract lengths. Their prices aren’t the cheapest when compared to other fixed-rate plans with bill credits, but they’re affordable.
Popular plans include Green Fixed Rate + Bill Credit, Fixed Rate + Bill Credit + A/C Protect Plus, and Fixed Rate + Bill Credit.
Their Green Fixed Rate plan includes 100% green energy with locked in rates for 12 months.
Their A/C Protect plan includes coverage for A/C and HVAC systems, while the A/C Protect Premier plans also include an annual HVAC tune-up.
Key features all of these plans include:
- Fair rates per kWh
- Monthly bill credits
- Early Termination Fees (ETFs)
- Base monthly charges
- Transmission & Distribution (TDU) fees
Note that these plans all feature monthly bill credits. That means they advertise a low rate, but those rates will only apply if your home falls with very set kWh usage ranges. If you fall below or extend above a set range, you may end up paying a much higher rate than advertised.
Be certain to carefully read the Electricity Fact Label (EFL) for such plans.
Tiered Rate Plans
The company also provides tiered rate plans, which means the rate per kWH varies based on the amount of kWhs your home uses. Please note that while this plan type advertises a very low rate, you may end up with a shocking electric bill surprise if you stray outside of your tier’s usage level.
Renewable Energy
As a part of their efforts to decarbonize the energy market and meet sustainability goals, Constellation Energy offers 100% carbon-free energy, using clean energy sources like solar, wind, and hydro.
If you’re looking for affordable renewable energy to reduce your home’s carbon footprint, their Green Fixed Rate plan may be a good fit for you.
If you want the best rates on clean energy, you might consider Gexa. They often have the best rates on green energy, if your home’s usage falls within set levels, found in their Electricity Facts Label (EFL).
Commercial Energy
Constellation also offers commercial energy for businesses. They have robust experience providing affordable business rates, as well as public sector expertise. Many major businesses, including Fortune 100 companies, rely on Constellation for their commercial energy needs.

Transferring Your Electricity Plan
You can conveniently transfer your energy plan when you move to a different address in Texas that benefits from deregulation. Give them a call to discuss your change of address at least a month in advance of your move.
Does Constellation have a cancellation fee?
Yes, Constellation often charges an Early Termination Fee (ETF), typically $150. To cancel your plan, simply call a Constellation operator or cancel via your online account. Be sure to check your plan’s Electricity Facts Label to determine the ETF before canceling your contract.
You can often avoid an ETF when moving outside of Constellation’s service area or if you wait to cancel until the final 14 days of your term.
