Fixed-rate electricity plans lock in your price per kWh for the full length of your contract — typically 6, 12, or 24 months. That means your energy charge stays exactly the same whether summer demand spikes or wholesale prices surge. For Collinsville households on Oncor Electric, a fixed-rate plan is the single best way to protect your budget from price volatility and avoid bill shock during Texas heat waves.
All rates in ¢/kWh for ZIP 76233. Oncor Electric delivery fee billed separately. Updated daily from licensed Texas REP data.

★ 1,000 kWh is the Texas standard usage benchmark. Rates include energy charge; TDSP delivery fees billed separately.
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 Collinsville, 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.
Compare by what matters most to you.
