Reliant Energy vs Gexa Energy.Which is actually cheaper?
Smart home bundles vs pure low-rate play. Voltcheckr calculates the real effective rate of every plan at your actual usage — not just the advertised rate.
Moving in? No bill needed — just your ZIP and home size.
Who wins?
Gexa wins on raw effective rate at 1,000+ kWh for most months of the year. Reliant wins if you genuinely shift 35%+ of usage to overnight hours (EV owners, pool pumps). For the typical Texas household running AC from 3pm-9pm, Gexa's bill-credit plans beat Reliant's free-nights plans by 1-2¢/kWh on the effective rate. The Nest thermostat Reliant bundles has a retail value of $130 — but you're paying for it through a 1.5¢/kWh premium over 12 months, which costs $180-$200 at average Houston usage. Just buy the Nest separately and take the cheaper Gexa plan.
