Weslaco residents in zip code 78570 have access to one of the most competitive retail electricity markets in South Texas. Served by AEP Texas Central (AEP-Central) for delivery, this Hidalgo County city of 41,731 residents benefits from full deregulation — meaning 18 licensed retail electric providers (REPs) are actively competing for your business right now. In March 2026, shoppers in 78570 can choose from 76 total plans, including 67 fixed-rate options and 6 green/renewable plans. With a median household income of $37,250, finding an affordable, stable electricity rate matters deeply here — and the good news is that competition is working in consumers' favor, with the most competitive rates starting well below the market average.
The most competitive rate available in 78570 right now is 9.5¢/kWh, offered through the True Power AEPTCC 12-Month Fixed Residential plan from True Power. That's a meaningful discount compared to the average rate across all 76 available plans, which sits at 12.9¢/kWh — and a dramatic difference from short-term plan averages. The wide spread between the best rate and the average rate (roughly 3.4 cents per kilowatt-hour) underscores just how much money Weslaco residents can save by actively comparing options rather than defaulting to whatever plan they're currently on. For a household using 1,200 kWh per month — typical during mild spring months in the Rio Grande Valley — that difference translates to roughly $40 in monthly savings.
Contract length has an enormous impact on your electricity cost in 78570. Here's what the data shows for March 2026:
For most Weslaco homeowners, a 12-month fixed-rate plan offers the best combination of rate stability and competitive pricing heading into the high-demand summer months.

The entire Rio Grande Valley experiences some of the most intense summer electricity demand in Texas, with temperatures regularly exceeding 100°F from June through September. Locking in a fixed rate now in March 2026, before summer demand peaks, is a widely recommended strategy for Weslaco households. Rates in the broader AEP-Central South Zone tend to rise as summer approaches, making early spring one of the best windows to secure a competitive fixed-rate plan.

Lock in a 12- or 24-month fixed-rate plan before June to shield your household budget from summer demand spikes. Weslaco's July and August heat can push spot electricity prices sharply higher on variable-rate plans during peak grid stress periods.
If you're a Winter Texan spending only the cool months in Weslaco, look for short-term or month-to-month prepaid electricity plans with no cancellation fees — they offer maximum flexibility without locking you into a full annual contract.
Set your thermostat to 78°F when home and 85°F when away during Weslaco's long summer season. Each degree of cooling below 78°F can increase your air conditioning energy use by roughly 6–8%, a significant cost in a subtropical climate.

Check eligibility for the LITE-UP Texas program if your household income qualifies — this state assistance program can reduce your monthly electricity bill by a percentage discount applied directly through your REP, providing real relief during the Valley's highest-cost summer months.
