San Marcos, home to Texas State University, has a unique electricity market with a high proportion of renters and students alongside a growing permanent resident base. Served by Oncor, San Marcos residents can choose from the same range of statewide providers as any other Oncor territory. Smaller apartments housing 1–2 students often use 500–800 kWh monthly, well below the 1,000 kWh benchmark used by most advertised rates.

Students and renters in San Marcos should focus on plans that look good at 500–700 kWh rather than 1,000 kWh; many advertised 'low rates' assume usage thresholds that renters never hit.

Who Delivers Electricity in San Marcos

Oncor (your delivery utility)

Oncor owns and maintains the poles, wires, transformers, and meters in San Marcos. They handle outages and infrastructure, but they do not sell electricity plans. You choose a retail provider separately, and Oncor delivers the power regardless of which provider you pick.

Oncor's delivery charges are the same for every customer in Hays County, regardless of retail provider. TrueBill includes these charges in every estimate.

Typical Electricity Usage in San Marcos

Summer (June–September)
700–1400 kWh
Air conditioning drives peak usage. Plans with bill credits at 1,000 kWh may not help much if summer usage regularly exceeds that level.
Winter (December–February)
450–900 kWh
Mild San Marcos winters keep most homes in the low-to-mid usage range. Electric heat can push this higher in colder years.

Frequently Asked Questions About Electricity in San Marcos

What electricity plans are best for students in San Marcos?
Students and apartment renters using 500–800 kWh monthly should avoid plans with large bill credits that require 1,000+ kWh to unlock. Instead, look for straightforward plans with low base charges and moderate per-kWh rates. Month-to-month or short-term plans also make sense for academic-year leases.
Does Texas State University affect local electricity rates?
Retail electricity prices in San Marcos are the same as anywhere else in the Oncor territory. The university has its own power contract but that does not affect what residents pay. Strong competition among providers keeps San Marcos rates in line with the broader Oncor market.
Are there no-deposit electricity plans available in San Marcos?
Yes. Several Texas providers offer plans with no deposit for customers with good credit, or pre-paid electricity plans that require no credit check. Pre-paid plans work like a debit card; you load money, usage draws it down, and you get low-balance alerts. These are popular with students who may lack Texas credit history.
Can I switch electricity providers in San Marcos?
San Marcos is in the Oncor deregulated service territory for choice-eligible addresses. Retail choice may not apply to every address in the metro area. Use your exact ZIP in compare flow to confirm eligibility and available plans.
Why can advertised electricity rates differ from my bill estimate?
Advertised rates often assume specific usage levels and plan conditions. Estimated cost at your own monthly usage can differ depending on credits, fees, and delivery charges. Plan terms may change, so confirm final details directly with the provider.
