Solar-Friendly Utility Providers in Dallas-Fort Worth: The Complete Guide

If you’re considering solar for your DFW home, one of the most important factors in the math is which utility serves your address. Texas has a uniquely complicated utility landscape — your “utility” might be one of several different types of entity, and each treats solar differently. Some are deeply solar-friendly with strong incentive programs. Others are workable but not exceptional. A few are restrictive enough that they meaningfully affect the economics of going solar.

This guide explains the DFW utility landscape from a solar perspective: which utilities serve which areas, how each handles solar, and how to figure out exactly which utility provides power to your specific address. Contact us for a free consultation to discuss how solar would work given your specific utility.

Texas Has Two Types of “Utilities” — Understand the Difference First

The single most important distinction to grasp before evaluating “solar-friendly” utilities in DFW: most people in DFW have two different companies involved in their electric service.

The Transmission and Distribution Utility (TDU) owns the wires, transformers, and infrastructure that physically delivers electricity to your home. They read your meter and handle the physical interconnection of new equipment (including solar). Examples: Oncor, CoServ, Tri-County Electric Cooperative.

The Retail Electric Provider (REP) sells you the actual electricity and sends you the monthly bill. Examples: Reliant, Direct Energy, TXU Energy, Green Mountain, Chariot Energy.

This split exists because Texas deregulated its electricity market in 2002. The TDU and the REP are different companies. They have different rules. They affect your solar economics in different ways.

For solar specifically:

• The TDU controls interconnection — how your solar system physically ties into the grid and any program incentives (like Oncor’s Take A Load Off Texas)
• The REP controls compensation — whether you get paid for excess solar generation, and how much

Important exception: cooperatives and municipal utilities. Some areas of DFW are served by electric cooperatives (CoServ, Tri-County, Grayson-Collin) or municipal utilities (Garland Power & Light, Denton Municipal Electric). In those areas, you don’t have separate TDU and REP — the cooperative or municipal utility handles both functions. They set their own solar policies independently of the deregulated market.

With that framework in mind, here’s the DFW landscape.

The TDUs Serving Dallas-Fort Worth

These are the wires utilities that physically deliver power to most DFW homes. The TDU serving your address is determined entirely by location — you can’t choose your TDU.

Oncor Electric Delivery

The largest TDU in DFW and one of the largest in the U.S. Serves most of the Dallas-Fort Worth Metroplex including Dallas, Fort Worth, Arlington, Plano, Frisco, McKinney, Carrollton, Richardson, Garland (delivery only — see GP&L below for retail), and dozens of surrounding cities.

Solar-friendliness: Strong. Oncor has a relatively streamlined interconnection process and runs the Take A Load Off Texas program — a substantial incentive for solar paired with battery storage. The incentive is paid to your installer, who passes the value to you. Learn more about the Oncor Take A Load Off Texas program.

Solar customers on Oncor’s grid also benefit from access to the full Texas deregulated REP market, which means you can shop for the best solar buyback plan from dozens of REPs (more on REPs below).

CoServ (Denton County Electric Cooperative)

Member-owned cooperative serving large portions of Denton County, parts of Collin County, and slivers of surrounding counties. Notable areas include parts of Frisco, Little Elm, Aubrey, Sanger, Krum, and Argyle.

Solar-friendliness: Generally workable. CoServ offers solar interconnection and has historically offered some form of net metering or buyback for solar customers, though terms have shifted over the years. Because CoServ is a cooperative (not part of the deregulated market), you can’t shop different REPs in CoServ territory — CoServ handles both delivery and electricity sales. Verify current solar policies directly with CoServ before installing.

Tri-County Electric Cooperative

Serves portions of Tarrant, Parker, Wise, Hood, Jack, and other counties on the western side of DFW. Important for rural Fort Worth area and Weatherford-adjacent areas.

Solar-friendliness: Variable. Tri-County allows solar interconnection but their buyback or net metering structure has been more conservative historically than Oncor or CoServ. Worth verifying current policies if you’re in their service area.

Grayson-Collin Electric Cooperative (GCEC)

Serves parts of Grayson and Collin counties on the northeastern edge of DFW. Includes some areas near Anna, Melissa, and parts of McKinney.

Solar-friendliness: Variable. GCEC handles solar interconnections but their solar program structure differs from Oncor’s deregulated market approach. Verify current terms before installing.

Wise Electric Cooperative

Primarily serves Wise County, with some adjacent coverage. Most relevant for customers in the Decatur and Bridgeport area.

Solar-friendliness: Cooperative model with their own interconnection process. Verify current solar policies.

Farmers Electric Cooperative

Serves portions of Collin, Denton, Fannin, Grayson, and other northeastern Texas counties.

Solar-friendliness: Has historically offered net metering and contract buyback for excess solar generation, plus compensation for renewable energy credits in some programs. Generally workable for solar customers in their service area.

Municipal Utilities in the DFW Area

City-owned utilities operate independently of the deregulated market. If your home is in one of these cities’ service areas, you don’t choose a REP — the municipal utility handles your electricity entirely.

Garland Power & Light (GP&L)

Serves the city of Garland. Notable for having one of the better solar policies among DFW municipal utilities. GP&L has historically offered full retail credit net metering with no aggregate generation limit — meaning solar customers can size systems generously without hitting program caps. The interconnection process is relatively straightforward.

Solar-friendliness: Strong. GP&L is often cited as one of the more solar-friendly municipal utilities in DFW.

Denton Municipal Electric (DME)

Serves much of the city of Denton (note: parts of the Denton area are served by CoServ, not DME — verify your exact address). DME offers a renewable energy program and supports solar interconnection.

Solar-friendliness: Workable. DME’s specific buyback terms have varied over the years; verify current details.

Greenville Electric Utility System (GEUS)

Serves Greenville, Texas (outside DFW proper but in our extended service area). Offers net metering and a 100% renewable energy program.

Solar-friendliness: Reasonable. The 100% renewable program is interesting for customers who want their non-solar electricity to be renewable-sourced.

Other municipal utilities in surrounding areas operate with varying solar policies. We can advise on specific programs during your consultation.

The REPs (Retail Electric Providers) — What They Mean for Solar in Oncor Territory

If you’re served by Oncor (most of DFW), you have access to dozens of REPs competing for your business. The REP you choose has a major impact on your solar economics because the REP is who buys back your excess solar generation.

Major Texas REPs offering solar buyback plans include:

• Chariot Energy — solar-focused REP with strong buyback programs
• Reliant Energy — large incumbent with solar plan options
• Green Mountain Energy — renewable-focused REP with multiple solar plans
• Direct Energy — major REP with solar buyback offerings
• TXU Energy — incumbent REP, also offers free nights/weekends plans that pair interestingly with solar + battery
• Champion Energy — historical buyback provider
• Shell Energy — newer entrant to retail buyback
• Several others including Constellation, Pulse Power, Gexa Energy

Each REP has different rates, contract terms, rollover policies, and minimum/maximum system sizes. Some are much better for solar customers than others.

This is a separate topic with substantial detail. Read our complete guide to Texas solar buyback plans for the full comparison framework.

The key point for this page: Your REP choice matters most if you’re in Oncor’s territory or another deregulated TDU. If you’re in a cooperative or municipal utility’s territory, you don’t have REP options — your utility handles everything.

Oncor’s Solar Programs in Detail

Because Oncor serves most of DFW, their specific solar programs deserve additional attention:

The Take A Load Off Texas Program

Oncor’s residential solar incentive for systems paired with battery storage. The program pays for solar-plus-battery installations in Oncor’s service territory, with the incentive amount calculated based on system size, expected solar production, panel orientation, and battery configuration. It’s not a fixed dollar amount per panel or per kWh — the calculation is more complex.

The incentive is technically paid to the solar installer (a commercial entity), who passes the value along to the homeowner in project pricing.

Eligibility requirements:

• Located in Oncor’s service territory
• New solar installation (not a retrofit of existing solar to add battery)
• Solar paired with battery storage (the program requires both)
• System sized between 3 kW and 15 kW DC
• Grid-tied (not off-grid)
• Properly designed and commissioned to program specifications

We handle the application as part of our standard installation service. Read our complete Oncor Take A Load Off Texas guide here.

Oncor’s Solar Interconnection Process

Standard process for any new solar installation in Oncor territory:

1. Pre-installation design submission and approval
2. Installation by qualified installer (including any required Oncor-side meter work)
3. Final inspection and commissioning
4. Permission to Operate (PTO) — the official “live” signal

Typical timeline: 4-8 weeks from contract signing to PTO, depending on permitting volumes and Oncor’s current processing speed.

How to Find Out Which Utility Serves Your Address

Sometimes the trickiest part is figuring out which utility actually serves your specific address. Cities don’t have clean boundaries here — neighboring streets can be on different utilities.

Easy ways to check:

1. Look at your electric bill. The TDU (if you’re in Oncor territory) or utility (if you’re in a cooperative/municipal area) is usually listed somewhere on the bill. For deregulated customers, both your REP and TDU should be referenced.
2. Check the Public Utility Commission of Texas (PUC) website — they have an address lookup tool that identifies your TDU.
3. PowerToChoose.org — Texas’s state-run REP comparison site. If you enter your ZIP code and it shows REP options, you’re in a deregulated market (most likely Oncor). If it shows no options, you’re in a cooperative or municipal utility area.
4. Ask us during your consultation. We can identify your utility based on your address as part of the project evaluation.

Common Confusion Points About DFW Utilities and Solar

A few misconceptions worth clearing up:

“My REP is my utility.” Mostly no, if you’re in a deregulated area. Your REP (TXU, Reliant, etc.) sells you electricity but doesn’t deliver it. Oncor (or whoever your TDU is) delivers the physical power. For solar purposes, both matter — but they do different things.

“Oncor doesn’t buy back my solar.” Correct. Oncor is your wires utility, not your electricity seller. Your REP buys back your solar (if your plan includes buyback). Oncor’s solar program (Take A Load Off Texas) is a separate one-time installation incentive, not ongoing buyback compensation.

“Switching REPs will affect my solar system.” No. Your solar system is physically connected to Oncor’s grid, which doesn’t change when you switch REPs. The REP change only affects who bills you. Your solar continues operating identically.

“I have to choose a solar-specific REP.” Not exactly. Most REPs offer at least one solar plan, though plan availability and rates vary. Some REPs (like Chariot Energy) are solar-focused. Others offer solar plans alongside their standard plans. Either approach can work depending on the specific plan terms.

“All Texas utilities offer net metering.” No. True 1-for-1 net metering is rare in Texas now. Most REP solar plans are some form of fixed-credit, wholesale-rate, or rollover-credit structure rather than traditional net metering.

“My HOA can block me from going solar.” Texas law (Texas Property Code §202.010) prevents HOAs from prohibiting solar installations. They can require reasonable aesthetic considerations, but they cannot block solar outright. Don’t let HOA concerns deter you.

Frequently Asked Questions

Which is the most solar-friendly utility in DFW? For most homeowners, Oncor offers the best combination of incentive program (Take A Load Off Texas), interconnection process, and access to the deregulated REP market for buyback. Garland Power & Light is also notably solar-friendly with strong net metering. CoServ, Tri-County, and other cooperatives are workable but vary.

Can I switch from a cooperative to a deregulated utility? No. Your TDU/utility is determined entirely by your physical address — you can’t switch to a different one. If you’re in a cooperative or municipal utility’s territory, you have whatever solar terms that utility offers.

Does Oncor offer net metering? Not directly. Oncor handles the physical interconnection but doesn’t bill you for electricity, so they’re not the entity offering “net metering” in the traditional sense. Your REP determines how your solar exports are compensated. Many REP solar plans function similarly to net metering even though Texas doesn’t have a statewide net metering law.

What if I’m right on the border of two utilities? The exact address matters. Two homes on the same street can sometimes be in different utility territories. Verify by checking your current electric bill or using the PUC’s address lookup.

Will solar work the same regardless of which utility I have? Yes, technically. Solar panels generate electricity the same way no matter which utility delivers your power. What changes is the financial side — incentive availability, buyback compensation, interconnection requirements.

Are there utilities I should avoid for solar? There’s no DFW utility that outright refuses solar interconnection — all are legally required to interconnect qualified residential solar systems. But the financial benefits vary significantly. We can help you understand what to expect for your specific utility during the consultation.

Does Tri-County or GCEC offer the Oncor Take A Load Off Texas incentive? No. That program is specific to Oncor’s service territory. Customers served by Tri-County, GCEC, CoServ, or other utilities don’t qualify for that specific program. Some of those utilities have their own (typically smaller) solar incentives — we’ll identify what applies.

What’s the difference between a cooperative and a municipal utility? Cooperatives (CoServ, Tri-County, GCEC, Farmers EC) are member-owned. Municipal utilities (GP&L, DME, GEUS) are owned by the city government. Functionally they’re similar for solar customers — both handle delivery and electricity sales without REP competition.

Can I get solar in a cooperative territory? Yes, in nearly all cases. All major DFW cooperatives allow solar interconnection. The specific terms and any compensation for exports vary by cooperative.

Do REPs care which TDU serves me? Usually no — REPs serve customers across whichever TDUs operate in the deregulated market. The TDU determines your physical service; the REP determines your billing.
