Everything you need to know about Constellation Energy

Constellation Energy offers comprehensive energy strategies at competitive pricing for electricity, natural gas and renewable energy plans. Together, we can reduce your business energy bills, provide you with energy security and even increase your company’s eco-friendly energy initiatives.

Constellation Energy commercial electricity plans

Energy rates are variable and subject to market availability and consumer demand. They change almost every minute. Constellation Energy plans are designed to reduce this fluctuation. With deregulation, energy suppliers must compete for consumers, driving down the energy costs while promoting more customer-centric service plans.

  • Fixed-Rate Plans: Fixed electric rates are locked in through a contract, ranging from 12-36 months, while keeping your individual rate consistent regardless of the current local electric rate. While the wholesale cost of electricity varies, these plans help keep your budget predictable and affordable, giving you the energy security you need.
  • Variable-Rate Plans: These rates are determined by the current state of the energy market. You get a cheaper rate when energy is abundant but pay higher rates in times of high demand or low production. These plans offer the flexibility of no contract but are high in risk.
  • Block and Index Plans: These hybrid plans offer unique combinations of fixed-rate and variable rate plans. For large commercial energy users, these plans provide flexibility and versatility.
  • Pre-Paid Plans: Constellation Energy does not currently offer pre-paid also known as no-deposit plans. Check our other providers for these types of plans. Find other providers.

Pro Tip: Most often, businesses prefer fixed rate plans. However, we can help you determine the best plan for your business. For instance, we know how to avoid nasty cancellation fees, rate hikes, minimum usage fees, and peak energy use times—basically being overcharged for the cost of doing business. Our energy experts consider all of these factors and more as we compare Constellation Energy electricity rates for your business. Contact one of our experienced Energy Consultants today!

Frequently asked questions about Constellation Energy

Will Constellation Energy require a deposit?

In general, a deposit is required in order to sign up with Constellation Energy. This deposit may be waived if your credit score meets particular requirements or if you can provide information validating how reliable a consumer you will be.

Will Constellation Energy charge me a cancellation fee?

With fixed-rate plans, most energy suppliers, including Constellation Energy, charge an “early termination fee” when you cancel a contract prior to its expiration date. These can vary between $50 to $99 and are determined by the length of time left on your contract.

What is the best Constellation Energy plan?

The fact is that your best energy plan may look different than that of other businesses. Energy plans are simply not one-size-fits all. It's true that most businesses prefer fix-rate plans, but other aspects such as energy source and contract length, or using a block and index plan may be recommended or even required to meet certain industry eco-standards.
