Factors to consider when choosing an electricity plan
Before signing up for a new plan, it’s helpful to understand some basics about Duncanville’s energy market. Here are some terms you should know:
- Fixed vs. variable rates: If you choose a fixed-rate plan, you’ll pay the same price per kWh for the length of your contract. However, with a variable-rate plan, your rate can fluctuate from month to month, depending on market conditions.
- Plan length: Fixed-rate plans have set contract lengths (the most popular being 12, 24, or 36 months). If you cancel within your contract period, your provider will typically charge an early termination fee (ETF). In contrast, variable-rate plans don’t come with contracts or ETFs. As a result, you’re free to switch providers or cancel your plan whenever you want.
- Same-day energy deadlines: Most energy companies in Duncanville can get your lights on within the same day — as long as you sign up before their cut-off time. To learn more about same-day electricity connections, give us a call at the number on this page.
- Renewable energy options: In Duncanville, there are a handful of electricity companies that specialize in green energy. Renewable energy plans are either powered by renewable sources (like wind and solar) or come with renewable energy credits (RECs) to reduce your carbon footprint.
- Electricity Facts Label (EFL): Every electricity plan in Texas comes with an EFL, which outlines its rate, term length, renewable content percentage, and other important information.
- Your usage needs: To choose the best plan for your home, it helps to understand how much energy you consume in a typical month. Plans often have multiple price tiers depending on your usage. Check your previous electric bills to find out how much electricity you use in a billing cycle.
