Constellation Energy is one of the largest and most respected energy providers in the United States. Headquartered in Baltimore, Maryland, Constellation has built a strong reputation by supplying electricity, natural gas, and renewable energy solutions to over two million residential, business, and public sector customers. The company officially launched as a standalone entity in 2022 after separating from Exelon Corporation, and since then, it’s sharpened its focus on delivering clean energy while offering customer-first services.

They pride themselves on making energy simple, reliable, and accessible whether you’re powering a small home or a large commercial space.

Coverage Areas

Constellation Energy Coverage Map

Constellation’s services are available across many parts of the United States, though exactly what’s offered can vary depending on where you live. Some of their main service areas include Connecticut, Delaware, Georgia, Illinois, Indiana, Kentucky, Maryland, Massachusetts, Michigan, Nebraska, New Jersey, Ohio, Pennsylvania, Texas, Virginia, Washington, D.C., and Wyoming. Texas residents have access to a wide variety of electricity plans through Constellation thanks to the state’s deregulated energy market. In places like the Northeast and Midwest, customers often have options for both electricity and natural gas services. Before choosing a plan, it’s always smart to confirm what’s available in your zip code, since offerings can differ not just by state, but even by city or utility provider area.

Types of Energy Offered

Constellation Energy offers a variety of energy options, making it easy to find a plan that matches your personal needs and values. They supply traditional electricity for homes and businesses, helping to keep your lights on, appliances running, and life moving smoothly. In select areas, Constellation also provides natural gas service, a popular choice for heating and cooking, with competitive rates and reliable delivery.

If you’re passionate about sustainability, Constellation has you covered with renewable energy plans powered by 100% wind or solar energy. These plans let you directly support clean energy initiatives without needing to install solar panels or change your daily habits. For those interested in rooftop solar, Constellation partners with local providers to offer solar installation services in certain areas.

Types of Plans

Constellation knows that one size doesn’t fit all, so they offer a variety of energy plans to fit different lifestyles and priorities. Here’s a deeper look into each:

Compare Constellation Plan Types

Fixed-Rate Plans:
The most popular choice for residential customers, fixed-rate plans lock in your price per kilowatt-hour for the entire contract term, usually anywhere from 12 to 36 months. This means your monthly bill will be predictable even if market prices swing up and down. It’s a great option if you like stability and hate surprises, especially during hot summers or cold winters when energy prices can spike.

Variable-Rate Plans:
For customers in Texas, Constellation offers variable-rate plans where your energy rate can change month to month based on the market. These plans often don’t require long-term contracts and offer more flexibility, which can be great if you’re planning a short-term stay. Just be aware that prices can rise during periods of high demand, so they’re better suited for customers who are comfortable with a little risk. If you are a renter or unsure how long you will be living in a certain place, a variable-rate plan might be a good option.

Renewable Energy Plans:
Want to make a positive impact on the planet? Constellation’s renewable energy plans use power sourced from 100% wind or solar energy. These are typically fixed-rate plans, so you still get price stability while knowing your home is running on clean energy. Some plans even include Renewable Energy Certificates (RECs) that verify your contribution to sustainable energy production.

Electric Vehicle (EV) Plans:
Constellation offers specialized plans designed for electric vehicle owners. These plans typically feature lower electricity rates during off-peak nighttime hours perfect for charging your EV while you sleep. It’s a smart way to save money if you’re part of the growing EV community.

A/C Protection Bundle Plans:
In certain markets like Texas, Constellation offers energy plans that come bundled with A/C protection. That means you not only get your electricity but also benefit from services like annual HVAC system inspections, diagnostics, and even discounts on repairs. It’s a perfect extra layer of protection during the long, hot summers.

Cancellation Fees

Cancellation fees are an important part of any energy contract, and Constellation is pretty upfront about theirs. For fixed-rate plans, if you cancel before the end of your contract, you may face an early termination fee (ETF) of $50-$150. However, Constellation tries to ease the risk for new customers with their 90-Day Satisfaction Guarantee: if you’re unhappy within your first 90 days, you can cancel your plan without paying a penalty.

For variable-rate plans, there usually aren’t any cancellation fees, one of the reasons they’re popular with people who want maximum flexibility. Also, if you’re currently under contract with another provider, Constellation sometimes offers promotions to cover up to $150 of your cancellation fees when you switch to them. Always double-check the fine print when signing up so there are no surprises!

Other Perks and Programs

One of the nice things about Constellation is they offer more than just energy. Customers can join the Constellation Rewards program, which gives you access to special deals, discounts, and even gift cards. In some areas, they also provide home services like HVAC repairs, maintenance plans, and plumbing services, a convenient way to bundle essential services with your energy bill.

For tech-savvy homeowners, Constellation supports smart home integration, offering plans that can work with smart thermostats and other connected devices. This not only helps optimize your energy usage but can save you money in the long run too. Plus, their mobile app and online portal make managing your account, paying bills, and tracking energy usage quick and easy.

Constellation Energy is a strong choice for anyone looking for reliable, straightforward energy service with a variety of plans to match different needs. Whether you want price protection with a fixed-rate plan, flexibility with a variable plan, or want to go green with renewable energy, they have an option for you. Their customer-centric approach, including perks like rewards programs, satisfaction guarantees, and smart home integrations, makes them stand out in a crowded marketplace.
