About Constellation Energy

Constellation Energy, formerly StarTex Power, is one of the largest electric companies in North America, but is not one of the top brands in relation to residential energy providers in Texas. They offer an assortment of fixed rate energy plans for various term lengths, as well as renewable energy plans.

BEWARE OF CONSTELLATION IMPOSTERS

If you are performing an online search for Constellation energy plans, you may find it confusing because numerous third party websites that include the name “Constellation” in their domain names and have the Constellation Energy logo in their banners, enroll consumers into what appears to be Constellation plans. To the average consumer, these sites would mistakenly appear to be owned by Constellation, but the fine print in the footer discloses that they are not owned or affiliated with Constellation, so this seems to be a deceptive practice by brokers posing as Constellation. It’s not clear which website Texas electricity customers can securely enter their information into when trying to sign up for Constellation electric rates.

HOW CONSTELLATION ENERGY COMPARES TO TOP ENERGY PROVIDERS

Constellation Energy usually does not have the best electricity rates in Texas and doesn’t attempt to provide the cheapest electricity plans, but they generally have energy rates that are competitive with large light companies. You can have the comfort of knowing that Constellation is a well established light company, especially in the commercial electricity market. They reportedly acquired StarTex Energy to gain a foothold in the Texas residential market. If you wish to view electricity rates from top residential electric companies in Texas to compare them to Constellation Energy rates (you’ll need to view Constellation’s rates on their site), input your zip code and home size into the box in the upper right corner of this page.

USE YOUR POWER TO CHOOSE IN TEXAS TO HELP THE PLANET

As green energy has become more price competitive with fossil-sourced energy, more residents are enrolling in renewable energy plans in Texas to combat climate change. Constellation Energy offers renewable energy plans, but also check the cheapest energy rates for green plans from Gexa Energy, TriEagle Energy, Pulse Power and Lone Star Energy. You have the power to choose Texas energy providers and electricity plans that best match your budget, values and needs.

Constellation Energy Rates & Plans in Texas

Constellation offers Texas electricity plans with a range of energy rates and contract lengths. Review the plan details and Electricity Fact Label for each Constellation rate plan to determine if it fits your home’s usage.

TYPES OF PLANS OFFERED BY CONSTELLATION

Constellation Energy electricity plans include fixed rate plans that lock in your energy rate for the term of the contract, variable energy rate plans that have floating rates, so-called free electricity plans that offer energy at no cost on nights and/or weekends, and 100% “green” renewable energy plans.

“FREE” ELECTRICITY AND GADGETS

Constellation energy rates that are free for specified days and times of day may cost you more than regular electricity rates due to your home’s usage patterns and the plan’s energy rate during non-free periods. Be certain to carefully read the Electricity Fact Label (EFL) for such plans. Also, our Electricity Fact Label guide for Texas electricity customers will show you how to use the EFL to choose the right plan for your home.

Check our promo codes page for availability of a Constellation Energy promo code. You will also find electricity promo codes for other top electric companies in Texas. Our exclusive promotional codes provide a discount off the rates of electric companies on their websites.

Constellation Energy Bill Pay

If you wish to pay your bill from Constellation online, visit the Constellation Energy Bill Pay page or pay by phone at the Constellation Energy phone number 866-917-8271. See operator hours in the section above.

It’s helpful to visit the Smart Meter Texas website and review your home’s electricity usage periodically to make sure the usage information on your Constellation bill matches your home’s meter usage.

 

Constellation Renewable Energy Plans

Constellation Energy is not categorized as one of the low rate energy companies in Texas, and their renewable energy rates are generally higher than those of energy providers such as Gexa Energy (which offers a 60-day Happiness Guarantee), TriEagle Energy (sister company to TXU), and Pulse Power and Lone Star Energy (credible discount providers). These alternative providers are considered to be high quality, cheap electric companies. You can find competitive, low renewable energy rates from competitors of Constellation at Home Energy Club.

SOURCES OF GREEN ENERGY IN TEXAS

Texas electricity comes from various renewable sources, especially solar energy and wind energy. Solar panels are used to generate solar power, while wind turbines are used in the generation of wind power. Constellation uses renewable energy credits to promote sustainable energy.

For a glimpse at how much CO2 traditional fossil-sourced energy plans emit into the environment, here’s our interesting and educational energy infographic.

 

Constellation Energy Reviews & Ratings

It’s highly recommended that you check Constellation Energy reviews from Texas citizens before locking in a Constellation energy rate. Here are Constellation reviews and ratings on their pages at Consumer Affairs, Google, and Yelp, which you may find insightful. On review sites, always scroll down the past the initial reviews to gain a more unvarnished view of consumer input. Also, note that consumers who post reviews about electric companies tend to have had negative experiences.

Switching, Moving In, Moving Out and Cancellation Fees

We created a very useful Savvy Shopper’s Texas electricity guide that will help you select an energy plan that matches your home and objectives if you are switching and wish to choose from other light companies in Texas.

If you use comparison websites like ours to compare energy plans, it’s useful to note that the Power to Choose Texas government website has had a large number of complaints and negative media stories because of their lack of quality control. The Texas Power to Choose site has been accused of displaying deceptive electricity plans which cause billing surprises. To learn more, perform an online search of stories about “Power to Choose”.

 

Transferring Your Constellation Energy Plan

You can conveniently have Constellation Energy transfer your energy plan when you move to a different address in a de-regulated area of Texas. Give them a call to discuss your change of address at least a month in advance of your move.

 

Report a Constellation Energy Power Outage

If you experience a Constellation Energy power outage, report it to Constellation, or for faster service, contact the Transmission and Delivery Utility (TDU or TDSP) in your area. In Texas, electric companies like Constellation, referred to as Retail Electricity Providers (REPs), function as marketing and billing companies and do not correct outages. TDUs repair outages and transmit electricity. See our handy Texas power outage phone directory.
