How Brownsville electricity works

AEP Texas Central handles delivery throughout Brownsville. TDU charges run about 4.97¢/kWh plus around $5.94 monthly. Standard South Texas TDU pricing, but with longer cooling seasons than DFW, your annual kWh usage is higher and small rate differences matter more.

The actual electricity rate — the part you can control — is set by your Retail Electric Provider (REP). In Brownsville, the most common providers are Reliant, Direct Energy, Gexa, Pulse Power, Just Energy. Switching providers takes 1-2 billing cycles and doesn't interrupt service.

Long cooling season = pick longer-term fixed plans

Brownsville runs AC roughly 8 months per year. A 24-36 month fixed-rate plan protects you from rate spikes through multiple summers. Don't shop short-term.

Watch for "Texas Power Promise" upcharges

Compared to inland Texas at the same temperature, Brownsville AC works 15-25% harder due to humidity. Dehumidifiers and ceiling fans help noticeably.

Don't fall for "free nights" without doing the math

Major Texas REPs offer Spanish-language support — confirm before signing if it matters. Reliant, Gexa, TXU, and Direct Energy all have established Spanish customer service operations.
