Just Energy vs. Constellation Energy: Service Areas
Just Energy is based in Houston, Texas, and Ontario, Canada, and provides electricity and natural gas services to customers in the U.S., Canada, and several other countries. The company also offers commercial energy rates and energy management systems.
Since offerings vary from state to state, you can look at this map to see which energy options are available in your service area.
Constellation Energy is based in Baltimore, Maryland, and offers energy solutions in 17 states and Washington, D.C. In addition to serving residential customers in these states, the company also caters to small businesses and commercial customers.
Both Just Energy and Constellation Energy are retail electricity providers (REPs), which means that they offer electricity in states with a deregulated energy market. Although they set their own energy rates, there may be delivery charges that they pass along from the local utility company that’s in charge of maintaining the distribution network.
There’s some overlap between their service areas: both companies offer energy plans in Ohio, Illinois, Massachusetts, and New Jersey. On the other hand, customers who live in New York can choose Just Energy but not Constellation, while customers in Georgia and Connecticut can choose Constellation but not Just Energy.
Why is there so much variation? Mostly, it comes down to regulations set by the Public Utility Commission of each state that determines what energy providers can offer. That’s why in states like Indiana, California, and Michigan, Just Energy offers natural gas but not electricity, and in Texas, they offer electricity, but not natural gas.

Just Energy Electricity Plans
There are plenty of plans to choose from at Just Energy. Whether you’re looking for renter options with flexibility, nights and weekends worth of free electricity, or simpler plans with price security, your choice is yours.
Here’s a quick rundown of your options:
Basic: Keep it simple with a no-frill, fixed-rate plan that comes with zero base charges. Plus, you have the option of choosing a longer contract for steady, affordable power without the guesswork.
Mega Saver: Perfect for maximizing value for high-energy families and households. With Mega Saver, get fixed-rate pricing designed for spacious homes, no base charges, and enjoy a $150 bill credit when monthly usage is 2,000 kWh or more.
Nights Free: Made for late-night lifestyles. Enjoy free electricity every night from 9 p.m. to 7 a.m., along with fixed daytime rates that keep your monthly bill predictable. Note that while this plan is not available for solar or distributed generation energy users, it’s still a solid pick for those who power up in the dark.
Weekends Free: Have great weekends without worrying about energy costs. From Friday evening through Sunday night, your electricity is free, giving you flexibility for family time, chores, and entertainment. Outside of the weekend window, you’ll still benefit from reliable fixed-rate pricing. Explore our free weekends plans.
Renters Choice: Designed with flexibility in mind. This fixed-rate plan lets renters enjoy affordable electricity with the freedom to cancel anytime, penalty-free. You can take this plan wherever you move, from apartments, condos, to rental homes.
These are just a few of the electricity plans offered by Just Energy, and available options may vary depending on where you live.

Constellation Energy Electricity Plans
Constellation Energy provides a range of fixed-rate electricity plans with unique perks, from bill credits for high usage to EV-friendly overnight rates. While their pricing is often slightly higher compared to Just Energy, Constellation differentiates itself by also offering home service add-ons in some areas, such as HVAC protection.
Here are a few of their popular residential plans:
12 Month Usage Bill Credit: A straightforward fixed-rate plan with generous bill credits available for households with consistently high electricity usage. Best suited for larger homes or families with higher consumption, like those with pools or heavy cooling needs. Comes with a standard early termination fee if you cancel before the contract ends.
24 Month Usage Bill Credit: Like the 12-month version, but with a longer contract term for customers looking for extended price protection. This plan also rewards higher monthly usage with bill credits, making it a solid fit for big homes or families with above-average energy demands.
12 Month Electric Vehicle FlexCharge Plan: Tailored for EV owners, this plan offers reduced overnight electricity rates between 10 p.m. and 6 a.m. Designed to encourage charging during off-peak hours, it helps lower costs and supports grid stability. All usage is matched with renewable energy certificates, so you can power your car while supporting a cleaner energy future.
Fixed-Rate Green Plan: A renewable option for households that want sustainability and predictability. This plan locks in a fixed electricity rate for the length of your contract, with all usage matched with renewable energy certificates sourced from wind and/or solar generators. Available across Constellation’s service areas, it’s an easy way to make your home eco-friendlier without needing solar panels.
