Why Choose a Fixed Rate Plan?

Fixed pricing gives you predictability. You know exactly what you'll pay per kWh the day you enroll — and that rate doesn't change until your contract ends. This is especially valuable in Prosper, where August temperatures routinely push electricity demand (and spot prices) to their highest levels of the year. Most fixed-rate plans also include a straightforward cancellation fee, so you can switch if a better deal appears.

Frequently Asked Questions

What is the cheapest fixed-rate electricity plan in Prosper?

The lowest fixed-rate plan in Prosper today is Octopus Energy — Octopus Lite 12 at 9.8¢/kWh for 1,000 kWh. At 500 kWh the rate is 22.7¢/kWh and at 2,000 kWh it is 15.8¢/kWh. Rates are pulled live from licensed Texas REP plan data.

How long do fixed-rate plans last in Texas?

Texas fixed-rate plans range from 3 months to 5 years. The most common terms are 12 and 24 months. Shorter terms give you more flexibility to re-shop; longer terms lock in today's rate for maximum price stability. If you break a fixed-rate contract early, most providers charge a cancellation fee of $50–$300.

Is a fixed rate or variable rate better for electricity in Texas?

For most Texas households, fixed-rate plans are the safer choice. Texas electricity prices can spike dramatically during extreme heat or cold — the February 2021 winter storm saw some variable rates hit $9/kWh. A fixed-rate plan eliminates that risk entirely. Variable rates may be cheaper in mild months but offer no protection against market surges.
