TexSun Solar home Texas utilities
Find your utility.
Thirteen starting points, each with its official source. Texas has many more utilities and cooperatives; your bill is the authority on who serves your home.
Look on your bill for the company named next to delivery charges, or the utility that bills you. Summaries were checked on September 26, 2026; follow each source for current terms.
Delivery utilities with a separate retail provider
The utility delivers the power; you choose and pay a retail electric provider, who sets any buyback terms.
Oncor
Oncor's solar page says the installer applies, Oncor reviews and may study the system, an interconnection agreement is signed, and Oncor then gives written permission to operate.
Energy sent to the grid is recorded by the advanced meter and passed to your retail electric provider, starting with the first full billing cycle, typically 30 to 60 days after permission to operate.
Your retail electric provider, not Oncor, sets any buyback or credit, so there is no single export value.
Delivery-related charges continue to apply for homes with solar.

CenterPoint Energy Houston Electric
CenterPoint's page says the installer applies, followed by a design review, construction, a final review and permission to operate.
CenterPoint handles the connection, the permission and the meter; your retail electric provider handles buying and selling energy on your bill, and buyback offers vary by provider.

Texas-New Mexico Power (TNMP)

Entergy Texas
Entergy Texas's distributed generation page says systems up to 100 kW can qualify under Schedule SQF.
For qualifying renewable systems up to 50 kW whose interconnection was initiated on or after November 29, 2017, the default option bills all energy taken from the grid and credits exported energy at avoided cost. Check the current tariff for figures.

El Paso Electric (Texas)
El Paso Electric's Texas page recommends getting approval before you build. After a local inspection, the utility inspects, sets the meter and gives written authorization.
It bills net use at the applicable rate and net production under Rate 48, so solar customers still get a bill. Its New Mexico rules are separate.

SWEPCO
SWEPCO's solar page says to apply before installing or connecting, and that compensation follows current rates set by regulators.
Changing a system needs an updated application, and ordinary grid-connected solar may not power the home in an outage. Texas customers should use the Texas handbook.

Xcel Energy (Southwestern Public Service, Texas)
Xcel Energy's Texas interconnection document describes two options: using solar to offset your own use, or a net billing arrangement tied to a variable fuel cost factor, with a fee. Ask its Texas interconnection team for current figures.

City-owned utilities
Run by a city, with their own solar rules.
Lubbock Power & Light (LP&L)
The City of Lubbock's solar permit application says permits in the LP&L service area need an approved interconnection agreement, and only licensed electrical contractors may obtain that permit. The same form also mentions a cooperative, so not every Lubbock address is served by LP&L.

Austin Energy
Austin Energy's Value of Solar page says customers are credited for all their solar production and billed for all the electricity they use, with leftover credit carried forward on electric charges. The credit rate can change and is not your retail price.
Its FAQ expects the next update in November 2026, subject to City Council budget review; a proposed value there is not an approved rate.

Electric cooperatives
Member-owned, with their own solar rules.
CoServ
CoServ's solar page says a distributed generation contractor applies, the member signs a tariff acknowledgment, CoServ reviews the system, and written permission to operate comes before it runs.
Adding panels or a battery later needs a new application.

Not listed here?
Many Texas homes are served by a cooperative, a city utility or another company we have not summarized. Ask your utility how it reviews and connects rooftop solar and how it credits exported energy. No single export credit or process applies to every Texas home.
We can help you prepare those questions: request a solar call, or email info@texsunsolar.com.
