CPL Plans and Rates in Texas

Unless you opted to choose another provider, Reliant Energy likely now manages your former CPL account. Reliant Energy offers prepaid and traditional electricity plans, as well as month-to-month plans and green energy plans. Below, we provide a quick reference for Reliant Energy’s electricity plan offerings, contact information and customer satisfaction ratings.

Reliant Energy Plan Types

Reliant Energy offers several types of electricity plans with several unique structures and some of the best rates for billing predictability. Plans offered to Texas residents include:

  • Fixed-rate plans: Lock in rates for up to 12, 24 or 36 months for more predictable monthly energy bills.
  • Time-of-use plans: Enjoy discounted — or free — energy rates during off–peak hours while paying very high rates during peak-demand hours.
  • Prepaid plans: Also called no-deposit plans, these plans bypass a credit check and upfront deposit but charge slightly higher energy rates per kilowatt-hour.

Overall, we recommend fixed-rate plans because our research indicates that they are the most straightforward. Additionally, they offer low-cost, predictable monthly energy bills.

Our Take on Reliant Energy

Reliant Energy is one of the largest and most trustworthy electric companies in Texas. It serves over one million residential customers and earned some of the highest scores in our review of nearly 100 energy providers in the State.
