    Cotulla, TX Utility Setup Guide

    Cotulla, the county seat of La Salle County in South Texas approximately 80 miles southwest of San Antonio, is a small community of around 4,000 residents with deep ranching and agricultural roots. If you're moving to Cotulla or already live here, understanding how to manage your utilities is essential. For electric service, Oncor Electric Delivery is the regulated utility that owns the poles, wires, and meters in your area—contact Oncor immediately if you experience an outage. For your electricity plans, billing, and customer support, you'll work with a retail electric provider like Ambit Energy, which is standard across Texas's deregulated electricity market. This separation means you can choose your rate plan while Oncor maintains the physical infrastructure. Cotulla's hot summers drive significant cooling costs from June through September, while winters are mild with minimal heating demand. Most households in the area use between 1,200 and 1,800 kilowatt-hours per month during peak summer months and considerably less in winter. When selecting an electricity plan, focus on competitive rates in the 1,000 to 2,000 kWh usage tier rather than advertised introductory rates at the 500 kWh tier, since that reflects where most households actually land over a full 12-month contract. Comparing plans across that realistic usage range will help you identify genuine savings for your family's actual consumption pattern.
