Georgetown, TX Electricity Rates & Plans

Last updated: October 18, 2026  ·  5 min read

Georgetown is one of the fastest-growing cities in the United States — a historic Williamson County city north of Round Rock that has become a major destination for retirees and remote workers drawn by its downtown square and Hill Country proximity. Despite its rapid growth, Georgetown remains served by Georgetown Utilities (GUS), a city-owned municipal utility. Georgetown residents cannot shop for competitive electricity plans. This guide explains why, what Georgetown Utilities rates look like, and what options Georgetown customers have.

Why Georgetown Has Georgetown Utilities — Not the Competitive Market

Texas's 1999 electricity deregulation law (Senate Bill 7) allowed municipal utilities to opt out of retail competition. Georgetown Utilities — which has served the city for over a century — chose to remain as a vertically integrated municipal utility rather than participate in the competitive ERCOT retail market. The Georgetown City Council sets utility rates through a formal public rate process.

Georgetown Utilities is notable among municipal utilities for its energy procurement strategy. The city entered into long-term wind and solar power purchase agreements that, on an annual portfolio basis, generate as much electricity as Georgetown uses citywide. Georgetown was widely recognized as the first city in the United States to be powered entirely by renewable energy on this annual accounting basis — a distinction driven by the economics of long-term renewable contracts rather than by any competitive market mechanism.

Georgetown Utilities Rate Structure

Georgetown Utilities uses a tiered residential rate structure — the first block of kilowatt-hours per month costs less per unit, and rates step up as monthly usage increases. The tariff includes an energy charge, a customer charge, and various riders. For Georgetown's current approved rate schedule, visit georgetown.org/utilities or call Georgetown Utilities at 512-930-3640.

Georgetown's Central Texas location means summer electricity demand is significant — July and August typically drive 1,000–1,600 kWh usage for a 3-bedroom home, with larger newer homes in Sun City and Wolf Ranch potentially higher. The tiered rate structure rewards conservation at every tier.

Georgetown ZIP Codes — GUS vs. Oncor Territory

ZIP	Area	Utility	Can Shop?
78626	Central Georgetown / downtown	Georgetown Utilities	No
78628	West Georgetown / Sun City	Georgetown Utilities	No
78633	North Georgetown / Lake Georgetown area	Georgetown Utilities (verify)	Verify by address
78681 (Round Rock border)	Georgetown / Round Rock fringe	May be Oncor	Verify by address

The service territory boundary between Georgetown Utilities and Oncor Electric Delivery is not perfectly ZIP-code aligned. Some addresses in ZIP codes that appear to be Georgetown may be in Oncor territory (and therefore deregulated). The only definitive way to confirm is to enter your specific address in the search tool — if competitive plans appear, your address is Oncor/deregulated.

Georgetown's 100% Renewable Energy Program

Georgetown's renewable energy story attracted national attention when the city completed long-term wind and solar power purchase agreements sufficient to match its annual electricity consumption on a portfolio basis. The economics that drove this decision were as much about price certainty as environmental goals — long-term renewable PPAs offered rate stability that fossil fuel-indexed power could not guarantee.

For residents, the practical result is that Georgetown's electricity is backed by a renewables-heavy portfolio. There is no separate "green energy premium" tier for Georgetown customers — the renewable sourcing applies to all customers by default. If rooftop solar is of interest, Georgetown Utilities has a residential interconnection program, though the terms may differ from standard net metering given the city's existing renewable procurement.

How to Lower Your Georgetown Utilities Bill

Since Georgetown residents cannot switch providers, bill reduction focuses on usage reduction and efficiency programs. Georgetown's tiered rate structure makes conservation particularly rewarding — every kWh that moves you from a higher tier to a lower tier saves the top-tier rate on all usage above that point.

Home efficiency improvements: Georgetown's warm climate means attic insulation, air sealing, and duct sealing are the highest-ROI investments for most homes. Sun City Georgetown's housing stock spans multiple decades; older homes in the original Sun City footprint may have 1980s-era insulation levels well below current standards.

Smart thermostats: Programmable thermostat setback during the peak afternoon hours (3–7 pm) in summer directly reduces demand and energy use without reducing comfort during occupied hours.

Rooftop solar: Contact Georgetown Utilities directly for current interconnection requirements, system sizing guidance, and buyback rates before investing in a solar system.

Frequently Asked Questions

Can Georgetown, TX residents shop for electricity plans?

No. Georgetown is served by Georgetown Utilities (GUS), a city-owned municipal utility operated by the City of Georgetown. Georgetown Utilities is not part of the deregulated Texas electricity market. Georgetown residents pay rates approved by the Georgetown City Council and cannot choose a different electricity provider.

Why can't Georgetown residents choose their electricity provider?

Texas electricity deregulation under Senate Bill 7 (1999) applied only to investor-owned utilities within ERCOT. Georgetown Utilities is a municipal utility — owned and operated by the City of Georgetown. Municipal utilities were allowed to opt out of retail competition, and Georgetown chose to remain as a vertically integrated municipal utility. Georgetown City Council sets utility rates.

What makes Georgetown Utilities unusual for a municipal utility?

Georgetown became widely recognized as the first city in the United States to be powered by 100% renewable energy on an annual basis. The city locked in long-term wind and solar contracts that, on a portfolio basis, generate as much electricity as the city uses annually. Residents still receive the same regulated service structure as any municipal utility — they cannot shop for plans — but the power mix behind their electricity is among the greenest of any utility in the US.

What are typical Georgetown Utilities electricity rates?

Georgetown Utilities uses a tiered rate structure. As of May 2026, the all-in effective residential rate runs approximately 10.0–14.0 cents per kWh depending on usage tier. Georgetown's rates have historically been competitive with the Texas average, though the long-term renewable energy contracts create some rate stability tradeoffs. Contact Georgetown Utilities at 512-930-3640 or visit georgetown.org/utilities for the current approved rate schedule.

Does Georgetown Utilities have a solar or net metering program?

Georgetown Utilities has a residential solar interconnection program. Since Georgetown already sources 100% renewable energy at the portfolio level, the value-of-solar credit structure and any net metering terms may differ from standard investor-owned utility programs. Contact Georgetown Utilities directly for current interconnection requirements, system size limits, and buyback rates before sizing a rooftop solar system.

If I move to nearby communities, can I get competitive electricity?

It depends on the community. Areas within city limits are typically Georgetown Utilities.
