Lewisville Electricity Rates

Edited by Rafael Morales
Last updated:

The cheapest True Fixed electricity rate in Lewisville today for a 12 to 23 month term is 11.6¢/kWh at 1,000 kWh, from Express Energy. Across the 46 True Fixed plans in that range we track in Lewisville, the average is 15.5¢/kWh. Both numbers account for the energy provider’s charges and all TDU delivery and base charges, so they reflect what you actually pay.

That 11.6¢ is the floor for a real fixed rate in Lewisville on a term of 12 months or longer. If you see a 12-month-or-longer plan advertised well below this rate, it is almost certainly a bill credit plan. Those rates only apply if your monthly usage lands inside a narrow window, usually right around 1,000 kWh. Over a year you will likely miss it in at least 4 months (overpaying $400 or more), using too little or too much. Clear Energy Facts does not recommend these plans.

Every plan listed here is True Fixed. If you are looking for a different plan type in Lewisville, we track those separately: Best Free Nights plans, Best Free Weekends plans, and No-credit-check prepaid plans.

Lewisville Housing & Heating Facts

Local housing and heating composition based on city profile inputs.

Median Year Built

1997

  • Lewisville has a large apartment population, and that is even more noticeable in ZIP code 75067, where renters make up about 60% of occupied housing. If you live in an apartment and your usage stays below 1,000 kWh for much of the year, avoid bill-credit plans. Those plans often look cheap at 1,000 kWh, but they can become expensive when your real usage falls below the credit threshold. 
  • February and August are the months with the highest bills. February can spike because of electric heating during cold weather, and August is usually the most expensive summer month because of air conditioning. The plans on this page and the bill estimates are for customers served by TNMP. If your address is in the Oncor area, your bill charges will be different.

What Happens If You Cancel Your Electricity Contract Early in Lewisville?

If you cancel your electricity contract before it expires, you will usually have to pay an early termination fee. In many cases, that fee is around $100 to $150 for a 12-month plan, and $200 or more for a 24-month plan or longer. The exact amount depends on your provider and the terms of your contract.

Even so, paying the cancellation fee can sometimes still be the better financial move. A lot of people in Texas, especially those who are not familiar with how the market works, end up paying far too much for electricity. If your current plan is costing you much more than the best plans available today, switching early may still save you money even after the cancellation fee.

For example, if you are overpaying by more than $500 over the remaining life of your contract, canceling may be worth it. In some cases, the savings can be much higher.

How do you know if canceling makes sense?
The only way to know for sure is to compare:
  •  your current plan 
  •  the early termination fee 
  •  the best plans currently available in Lewisville 

We created a comparison tool only for that purpose. The full process is explained in this article:  Can You Save Money Switching Electricity Providers?

In that guide, we show you how to compare your current plan against the best options in the market. Our tool helps you estimate how much you would pay if you stay, how much you would pay if you switch, and whether you would actually save money after the cancellation fee.

Types of Electricity Plans Available in Lewisville

If you are shopping for electricity in Lewisville, you will see several different plan types. Some are simple and easy to understand, while others depend on your monthly usage, the time of day, or special equipment in your home.

  • Truly Fixed Plans: These plans keep the same energy rate for the full contract term, which makes them one of the most predictable options in Lewisville.
  • Bill Credit Plans: These plans give you a bill credit only when your monthly usage falls within a certain range, so your real rate can change a lot from month to month. Almost all comparison websites feature this kind of plan.
  • Tiered Plans: These plans use different pricing levels based on how much electricity you use during the billing cycle. These plans are very common among large companies such as Reliant and TXU.
  • Free or Discount Nights Plans: These plans offer free or lower-priced electricity at night, but the daytime rates are often much higher. Reliant, TXU, Infuse, Revolution, Green Mountain, Amigo, and Just Energy are some of the companies that offer these kinds of plans.
  • Free or Discount Weekends Plans: These plans give you free or discounted electricity on weekends, but weekday pricing may be less attractive.
  • Buyback Plans: These plans are made for homes with solar panels and let you receive credit for extra electricity sent back to the grid.
  • Special Equipment Plans: These plans are linked to certain devices, such as smart thermostats, and may include special discounts or program benefits. Octopus and Think Energy are two companies that usually offer this type of plan.
  • EV Plans: These plans are designed for electric vehicle owners and usually offer better pricing during overnight charging hours.
  • Prepaid Plans: These plans let you pay in advance for electricity and usually do not require a long contract, though you must keep enough balance in the account.
  • Variable Plans: These plans do not lock in a fixed rate, so the price can go up or down each month.
