What are the current electricity market averages around San Marcos?

For statewide context, the latest Texas residential average from EIA is 16.39¢/kWh for Mar 2026, synced Jun 22, 2026.

Are Texas electricity prices expected to go up or down?

The latest EIA short-term outlook suggests Texas-area residential prices may move lower in the near term. The latest historical value is 15.69¢/kWh, and the next few forecast months average about 15.17¢/kWh based on the EIA outlook released Jun 8, 2026.

Why can the advertised rate be different from the final bill?

The advertised rate is only one part of the bill. Your final total can move because of usage tiers, bill credits, delivery charges from the utility, taxes, and the way a plan behaves at 500, 750, 1,000, 2,000, or 3,000 kWh. That is why SlashPlan compares plans across multiple usage levels instead of relying on one headline rate.

Should I compare plans at 500, 750, 1,000, 2,000, or 3,000 kWh?

Compare at the usage level that is closest to your home, then look at the surrounding usage points. Smaller apartments often land near 500 or 750 kWh, many homes cluster around 1,000 kWh, and larger homes or hotter months can move closer to 2,000 or 3,000 kWh. If a plan only looks cheap at one usage level, that is usually a sign to compare it more carefully before enrolling.

San Marcos sits on I-35 between Austin and San Antonio, with Texas State University and the spring-fed San Marcos River shaping much of the city's daily life. For local households, summer cooling, student housing, and everyday appliance use can all affect electricity costs, while small businesses need bills that are easy to forecast. San Marcos is generally served through municipal or cooperative utility service rather than Texas's competitive retail market, so residents should review their applicable rate schedule, billing options, and usage patterns. Understanding those details can help homes and small businesses manage electricity costs more confidently.

Why compare more than the headline rate

Keep the lowest advertised number in context

The best-looking rate at one usage tier is not always the plan that feels best on a real bill.

Electricity shopping is closer to comparing checkout totals than comparing one sticker price. Your plan, your usage, and the utility delivery charges all shape the final bill, so the best pick is the plan that still works once those pieces come together.

Usage-tier pricing can look very different at 500, 1,000, and 2,000 kWh.
Bill credits and minimum-usage rules can make a cheap plan expensive if your usage shifts.
Delivery charges still come from the utility even when you switch retail providers.
Fixed, variable, prepaid, and time-of-use plans do not carry the same billing risk.
