CoServ Solar Buyback: How It Works in 2026

If you're a CoServ Electric member and you've been looking into solar, most of what you've read probably doesn't apply to you. The majority of North Texas solar guides are written for Oncor territory — a deregulated market where you can choose your electric provider. CoServ operates differently, and understanding that difference upfront is what separates a solar investment that performs from one that disappoints.

CoServ Is a Co-op — That Changes Everything

CoServ Electric is a member-owned electric cooperative. When you pay your CoServ bill, you're not a customer of a deregulated utility — you're a member-owner of the co-op itself. That structure has one major consequence for solar buyers: you cannot choose a competing retail electric provider (REP).

In Oncor's service territory, homeowners have the freedom to shop for a REP — companies like Reliant, TXU, or Pulse Power — and some of those REPs offer plans that credit exported solar at the full retail rate (a so-called 1:1 buyback). In CoServ territory, that option doesn't exist. CoServ sets your buyback rate, and it's the same for every member with solar.

How CoServ's Solar Buyback Program Works

When your solar panels produce more electricity than your home is using at a given moment — midday in summer, for example — the surplus flows out to CoServ's grid. CoServ tracks this with a bi-directional meter installed at your home once your system is approved for interconnection.

At the end of each billing period, CoServ calculates your net usage: what you drew from the grid minus what your panels exported. If you exported more than you consumed, you receive a bill credit. If you consumed more than you exported, you pay for the difference at the standard retail rate.

What CoServ Actually Pays: The Avoided Cost Rate

Here's the part most homeowners don't hear until after they've signed: CoServ credits excess solar at the avoided cost rate — not the retail rate you pay for power you pull from the grid.

Avoided cost is the wholesale price of electricity that CoServ avoids purchasing from the market when your panels are producing. It's the co-op's cost savings, not your retail savings. In practice, this rate is significantly lower than retail.

As a rough illustration: if your retail rate is around 12–13 cents per kWh, CoServ's avoided cost rate may be in a range meaningfully below that. The exact figure changes based on wholesale market conditions and CoServ's tariff schedule. Contact CoServ directly for the current avoided cost rate before making any financial decisions.

What This Means for System Sizing

This rate gap changes the math on system sizing. Exporting excess power earns you significantly less per kWh than you'd save by consuming that same power yourself. That means:

• Oversizing your system (producing far more than you use) adds cost without proportional benefit
• The optimal strategy is a system sized to offset 90–100% of your annual consumption — not to maximize export
• Pairing solar with battery storage lets you capture midday surplus and use it in the evening, rather than exporting it at the avoided cost rate

CoServ's Solar Interconnection Process

The steps to go solar in CoServ territory are similar to Oncor, but you work with CoServ directly rather than through a deregulated application layer. Here's what to expect:

1. Solar system design — your installer designs a system sized to your usage. CoServ typically requires that systems do not exceed your historic annual consumption.
2. Interconnection application — your installer submits the application to CoServ on your behalf. This includes system specs, single-line diagrams, and equipment data sheets.
3. CoServ review — typically 15–30 days for standard residential systems. Larger or more complex systems may take longer.
4. Inspections — local city or county electrical inspection (required in most jurisdictions), followed by CoServ's own review of the completed installation.
5. Meter upgrade — CoServ installs a bi-directional meter at your location.
6. Interconnection Agreement — you sign CoServ's standard interconnection agreement, which outlines the terms of your buyback credit.
7. Permission to Operate (PTO) — once all steps are cleared, you receive written authorization to turn your system on.

Is Solar Still Worth It in CoServ Territory?

Yes — solar can make solid financial sense in CoServ territory. The avoided cost rate is a real constraint on export earnings, but it doesn't eliminate the case for solar. The key is approaching it with the right strategy:

• Size for self-consumption. A system designed to offset your own usage — not to maximize grid export — performs well under co-op rules. The savings come from power you don't buy, not from credits you earn.
• The 30% federal tax credit still applies. The Investment Tax Credit reduces your total system cost by 30%, dollar for dollar off your federal tax bill. That applies in CoServ territory just as in any other.
• Texas's solar property tax exemption applies. The added value solar brings to your home's assessed value is exempt from property taxes in Texas — regardless of whether you're in co-op or deregulated territory.
• Long-term electricity cost protection. CoServ rates, like all electricity rates, have risen over time. A solar system locks in a portion of your energy cost for 25+ years.
• Battery storage amplifies the value. In co-op territory specifically, a battery paired with solar can dramatically improve your return by shifting self-consumption into evening hours instead of exporting at avoided cost.

CoServ Territory and Our Service Area

CoServ Electric primarily serves Denton County and portions of surrounding counties in North Texas. Some communities within N-Tech's service area may fall within CoServ's service territory rather than Oncor's. The easiest way to confirm your provider: look at your electric bill. CoServ members will see "CoServ Electric" as their provider — there will be no separate REP listed, because CoServ serves both the distribution and generation functions for its members.

If you're unsure whether you're in CoServ or Oncor territory, or if you have a different cooperative serving your area, your electric bill will tell you. N-Tech will ask about your utility provider early in the consultation process to make sure your savings estimate reflects the correct buyback rate from day one.

A Note on Honesty

Some solar companies quote the same return-on-investment numbers regardless of whether a customer is in Oncor territory or a co-op. That's not accurate. The avoided cost rate matters, and a system designed without accounting for it will underperform relative to what was promised. We walk every customer through this before a single panel is ordered.
