Complete guide to Texas net metering: solar buyback plans, REPs & regulated utilities

Updated

It’s difficult to parse through everything you need to know about going solar in Texas - are the savings worth it?

Texas’ unofficial state motto might as well be, “Go big or go home”, so it should come as no surprise that the Lone Star State’s solar industry is one of the fastest-growing in the nation, with enough solar currently installed to power almost two million homes. In fact, the Solar Energy Industries Association (SEIA) recently named Texas as the second-best state for solar in the country, second to none other than California.

But what does come as a surprise is that Texas doesn’t have any statewide rules for solar net metering - the policy that saves homeowners money on their electricity bills by crediting them for excess solar energy their solar panels generate.

Instead, the state has a few solar buyback programs for Texans to take advantage of, which are, in a way, a form of net metering. However, the lack of official state net metering rules, paired with the way Texas’ electricity market works, makes it a bit difficult to navigate exactly what solar options might be available to you.  

But you’re in luck! We’ve broken down what you need to know about the solar buyback plans that are offered, whether or not you are even able to choose your own plan, and if solar is a worthwhile investment for you.

    Texas net metering at a glance:

    • Texas does not have a statewide net metering policy, but seven retail electric providers, as well as many municipal utilities and electric cooperatives offer some form of a solar buyback program.
    • Texans who live in a deregulated area of the state can pick a solar buyback plan from one of the following REPs (so long as they service your municipality): Green Mountain Energy, MP2 Energy, Octopus, Pulse Power, Rhythm, Reliant, or TXU Energy.
    • Pulse Power will most likely provide the highest solar savings because it does not put a cap on how much solar electricity it will purchase from customers.
    • If you live in a regulated area of Texas, you can only use the solar buyback plan offered by your utility company. Not all utilities offer solar programs.
    • Going solar in Texas is worth it for many homeowners, given they have access to a decent solar buyback program.
    • By entering a few pieces of information about your home, you can calculate the cost of solar panels (with and without a solar battery), as well as your projected savings and payback time through our solar calculator.

    Texas’ electricity market

    texas' electric market, regulated and deregulated

    Before we get into the details about solar energy in Texas, we first need to clear up what's going on in the state’s electricity sector. 

    Around 85% of Texas participates in a deregulated electricity market, while the remaining 15% of the state participates in a regulated electricity market. Whether or not you live in the deregulated part of Texas will impact what you need to think about when going solar. 

    Deregulated Texas

    With a deregulated electricity market, the supply of electricity is separate from the delivery of electricity. This presents a unique situation for solar homeowners in Texas that many homeowners in the rest of the United States don’t have to deal with. 

    The supply of electricity: Texans can shop around for electricity rate plans from different electric companies, called Retail Electric Providers (REPs). If you want to go solar in the deregulated part of Texas, you’ll want to find an REP that has a solar buyback plan so you can maximize your solar savings. Whichever REP you choose will impact if solar will be a worthwhile investment for you. 

    The delivery of electricity: Even though you get to pick your REP when you live in a deregulated area of Texas, you do not have a choice over what Transmission and Distribution Utility (TDU) you have. The four TDU companies in Texas are:

    The electric bill you receive from your REP will include REP electric charges, as well as TDU fees that get sent to the utility operating in your area. 

    Regulated Texas

    If you live in an area that has a regulated electricity market, you do not choose an REP. Instead, your municipal utility or electric co-op will handle both the supply and delivery of electricity to your home. 

    So, the only electricity plans and solar buyback options you have are the ones offered by the utility company in your area. 

    Solar buyback rates offered by REPs in Deregulated Texas

    Like we said before, if you live in a deregulated area of Texas, you’ll need to pick an REP. When you’re looking to go solar, you’ll want to narrow it down to REPs that offer solar buyback plans. 

    Out of the over one hundred REPs operating throughout the Lone Star State, only seven currently offer some kind of solar buyback plan, and they include:

    But beware, not all of the solar buyback plans offered by these companies are created equal. We’ve divided the solar plans offered by these REPs into three categories: 

    • 1. Uncapped credit plans
    • 2. Credit cap plans
    • 3. Real-time metering plans

    1. Uncapped credit solar buyback plans

    Offered by: Pulse Power 

    Note: Chariot Energy no longer offers a solar buyback plan. As of May 2022, Chariot Energy took its Rise 12 solar buyback plan off of its website. It’s unclear if it will offer a new plan in the future. But for now, don’t count on getting Chariot’s uncapped credit plan.

    Uncapped solar buyback plans will save the most money for solar homeowners in Texas, because there is no limit on how much excess solar power the company will credit you for. 

    uncapped credit plans

    You see, there might be a few months out of the year where your solar panels produce more electricity than your home uses. When this happens, Pulse Power will pay you for that excess energy in the form of a bill credit, which can be carried over to help reduce your energy costs on future electric bills, when your solar panels might not produce enough energy to cover all of your electricity needs.

    The solar buyback credits are valued at the “energy charge rate”, which is the same rate Pulse charges you for electricity you use from the grid. Keep in mind though, electricity use from the grid will have additional TDU charges included. 

    These are not included in the solar buyback rate, however, which means your solar buyback credit will be worth slightly less than what you pay Pulse Power for each kilowatt-hour (kWh) of grid electricity. 

    The following table outlines the solar buyback plans offered by Pulse Power:

    Table 1. Uncapped credit solar buyback plans
    REP Plan REP monthly base charge Import rate per kWh* Solar buyback rate per kWh
    Pulse Power Solar Buyback 12 month $4.95 $0.17 - $0.19 $0.09 - $0.13
    Pulse Power Solar Buyback 24 month $4.95 $0.15 - $0.16 $0.08 - $0.09
    Pulse Power Solar Buyback 36 month $4.95 $0.09 - $0.15 $0.07 - $0.09

    *Based on 1,000 kWh usage, including TDU fees; varies by location

    2. Credit cap solar buyback plans

    Offered by: Green Mountain Energy, Rhythm, Reliant, and TXU Energy 

    Like the name suggests, these REPs place a limit on how much solar energy the company will credit you for. These REPs all happen to have the same credit cap - you will not receive any credit for solar energy production that exceeds the amount of energy your home used during that month. 

    capped credit plans

    That’s a little confusing at first, but it’s easier to understand with an example. Let’s say your home used 500 kWh of electricity from the grid in one month. This means the maximum amount of solar energy your REP will credit you for is 500 kWh. Even if your solar system produces 700  kWh in a month, you will still only get 500 kWh in credits. 

    What about that extra 200 kWh of solar you produced? It just goes to the grid, and you get nothing for it. Because these plans limit how much solar energy the company will “buy” from you, you’ll get slightly lower solar savings than if you chose Pulse Power as your REP.

    Just like with Pulse Power, these four REPs credit solar energy at the energy credit rate, which does not include any TDU charges. So, you pay a little more money for energy you take from the grid than what your solar energy gets credited for. 

    Table 2. Credit cap solar buyback plans
    REP Plan REP monthly base charge Import rate per kWh* Buyback rate below energy usage (per kWh)
    Green Mountain Energy Renewable Rewards Perfect Match 18 $9.95 $0.17 $0.16
    Green Mountain Energy Renewable Rewards Perfect Match 36 $9.95 $0.17 - $0.18 $0.11 - $0.12
    Rhythm** Rooftop Solar Buyback 12 $8.95 $0.14 $0.10
    Reliant Energy** Solar buyback $5.00 $0.15 $0.10
    TXU Energy Renewable buyback 24 month $9.95 $0.15 - $0.16 $0.14 - $0.15
    TXU Energy Renewable buyback month-to-month $9.95 $0.15 - $0.16 $0.14 - $0.15

    *Based on 1,000 kWh usage, including TDU fees

    **Rates start as low as these values and are subject to increases depending on your location

    Money-saving tip: You should consider installing a smaller solar system to minimize your excess energy! You don’t want to pay $18,000 to install a solar system that generates electricity and 1) you can’t use and 2) you can’t even get paid for. 

    To avoid this, consider installing a smaller solar system that covers all of your spring or fall usage, but might not cover all of your sky-high summer electricity bills. No, you won’t eliminate all of your summer energy costs, but you will cut down most of it, while spending less on the solar installation.

    Your installer will work with you to determine the best size solar system to ensure your needs are met, without sending tons of extra energy to the utility that you won't get compensated for.

    3. Real-time metering plans

    Offered by: Octopus and MP2 Energy 

    Real-time metering (RTM) solar buyback plans operate a little differently than the other ones we discussed.

    The other six REPs provide credits based on your monthly net electricity usage and production. They look at the total amount of electricity that your home took from the grid, compare it to the total amount of solar energy your system sent the grid, and value your credits at the energy cost rate. 

    real time metering plans

    Octopus and MP2 Energy credit you on an instantaneous basis. This means at 12 PM when your solar panels produce 2 kWh more than your home needs, the REP is crediting you right then for those 2 kWh, instead of figuring out your net production at the end of the month. This wouldn’t really matter if the companies were crediting you at the energy credit rate, but they’re not.

    Instead, Octopus and MP2 Energy credit you for your excess generation at what the retail market price of electricity is at that exact moment. The retail market price of electricity fluctuates throughout the day, depending on factors like demand and where you’re located. 

    We can’t pin down exactly how much the retail market price of electricity will be, but it typically sits somewhere around $0.03 per kWh. There are extreme and rare cases where the real-time market price can be a couple bucks per kWh, which means your solar energy would be worth way more than what you pay, but these conditions are, like we said, extreme and rare. 

    Table 3. Real-time metering solar buyback plans
    REP Plan REP monthly base charge Import rate per kWh* Solar buyback rate per kWh
    MP2 Energy Solar Buyback 24 $0 $0.16 - $0.17 RTM
    MP2 Energy Solar Buyback 60 $0 $0.13 - $0.14 RTM
    Octopus Octo12 $10 $0.16 - $0.17 RTM
    Octopus Octo36 $10 $0.16 0 $0.18 RTM

    *Based on 1,000 kWh usage, including TDU fees

    So, what exactly does this all mean? Basically, because your solar generation is not netted against your energy consumption, and the rate that the REP pays you for excess solar energy is generally going to be much lower than the rate you buy electricity for. 

    Which REP should you pick?

    The right REP for you is going to depend on a ton of factors, including which REPs provide service in your area, the size of your solar system, what term length you’re looking for, and the amount of electricity you consume. 

    That being said, in general, the 36-month Pulse Power plan will likely give you the best savings. Not only does it have some of the lowest monthly base charges and electric rates, it doesn't limit the amount of solar energy it purchases from you - meaning your solar credits can offset your future electricity bills, leading to overall higher solar savings. 

    If Pulse isn’t an option for you, Rhythm’s plan can still take a decent chunk off of your electricity bill, plus it has a low base charge. TXU Energy is also a solid option, because its buyback rate is pretty close to what you pay for electricity, including TDU fees. 

    Overall, it’s a good idea to at least take a look at what each of the REPs are offering in your area and read the electricity fact labels the companies provide on their websites, which will give you an idea of how much electricity will cost you, as well as the rate your solar energy will be purchased for. 

    Solar buyback plans for utilities in Regulated Texas

    Going solar is a little more cut and dry for those who live in the 15% of the state that is regulated. Either your utility has some sort of solar buyback or it doesn’t. If the plan is good, it’s good; if it’s bad, it’s bad. 

    Let’s take a look at just a few of these regulated utilities and what kinds of solar programs they offer: 

    1. CPS Energy’s solar buyback plan

    If you live in the San Antonio area, you most likely get your electric service from CPS Energy. Even though you can’t choose which company you buy electricity from, the good news is CPS Energy does have a solar buyback plan called “net billing”.

    Under its net billing plan, solar energy up to your home's monthly usage will be credited at the full-retail rate of electricity. Any solar energy produced that exceeds your home’s energy usage for the month will be credited at a lower rate. 

    Unfortunately, a recent announcement suggests that this net billing program might not be around for much longer. CPS’ board is currently in talks to eliminate the utility’s solar incentive program, and is discussing potentially cutting its net billing program. We will update this article as soon as a decision is made.

    You can read more details about going solar with CPS Energy here

    Table 4. CPS Energy’s net billing plan
    Utility Plan Import rate per kWh Buyback rate at/below usage per kWh Buyback rate above usage per kWh
    CPS Energy Net Billing $0.12 $0.12 ~ $0.02

    2. Austin Energy’s solar buyback plan

    Austin Energy services the city of Austin, as well as some surrounding municipalities. The municipal utility has a different approach to solar billing than most utilities, not just in Texas, but throughout the country. 

    Instead of crediting solar energy at the retail rate or the real-time market price, Austin Energy credits solar energy at the Value of Solar rate. The Value of Solar rate, or VOS rate as it’s sometimes referred to, takes many factors into account, like energy savings that solar provides to the utility, how solar can reduce stress on the grid’s transmission and distribution system, and the environmental benefits that home solar provides. 

    When you go solar with Austin Energy, you will have a meter that measures just your solar production, and a separate meter that measures your home’s electricity consumption during the one-month billing cycle. Your electricity bill will also have two parts: the energy charges and the solar credit. 

    The energy charge will be equal to all of the electricity your home consumed, multiplied by the retail rate of electricity. The solar credit will be equal to all of the solar energy your panels produced, multiplied by the VOS rate. 

    If the solar credit is worth more than your total energy charges, the credit will roll over to the next month. Austin Energy provides an explanation of what your electricity bill will look like with the Value of Solar plan here

    Table 5. Austin Energy’s Value of Solar plan
    Utility Plan Import rate per kWh* Value of Solar rate per kWh
    Austin Energy (within city limits) Value of Solar $0.03 - $0.11 $0.097
    Austin Energy (outside city limits) Value of Solar $0.04 - $0.08 $0.097

    *Varies by electric usage

    Right now, the Value of Solar rate is higher than almost all residential electricity rate tiers, meaning your solar energy is worth more than grid energy! This makes going solar with Austin Energy a great investment

    Keep in mind though, solar credits will not offset any taxes or fixed charges on your bill. 

    3. Brownsville Public Utilities Board’s solar buyback plan

    Brownsville Public Utilities Board (BPUB) has over 52,000 total electric customers, and it offers its solar homeowners a solar buyback program similar to the real-time metering programs offered by Octopus and MP2 Energy. 

    Your electric meter will read, in real time, how much solar energy your solar panels are sending to the grid. That excess energy is valued at the Fuel & Purchase Energy Charge (FPEC), which you can find on BPUB’s website

    Table 6. BPUB’s solar buyback plan
    Utility Plan Import rate per kWh* FPEC (Buyback rate) per kWh
    Brownsville Public Utilities Board Solar buyback $0.05 - $0.08 $0.04

    *Varies by electric usage

    The structure of this program provides lower savings than some of the other utility programs in Texas, thereby making the investment in solar a little less lucrative with BPUB. 

    4. CoServ’s solar buyback plan

    CoServ is an electric cooperative that operates across six counties in North Texas. CoServ offers a solar buyback program for customers who want to install solar panels, and it works just like the credit cap REP plans we described earlier. 

    CoServ will credit your solar energy production at the retail rate of electricity up to your monthly energy usage. CoServ will not provide credits for any solar electricity generated above your monthly usage. 

    You can read our guide to going solar with CoServ here

    Table 7. CoServ’s solar buyback plan
    Utility Plan Import rate per kWh* Buyback rate below usage (per kWh)
    CoServ (Summer) Solar buyback $0.13 $0.13
    CoServ (Winter) Solar buyback $0.11 - $0.13* $0.11 - $0.13*

    *Varies by electric usage

    5. Entergy Texas’ solar buyback plans

    Entergy Texas has almost 500,000 electric customers across its service area, which spans 17 counties in southeastern Texas. Entergy offers three separate options for solar owners under its net metering program: Option 1, Option 2, and Option 3. 

    Under Option 1, Entergy will not purchase any electricity produced by your solar system. You would have one meter installed that measures your net electricity consumption, and if you sent any electricity to the grid, you’re not getting credits for it. 

    Option 2 will provide the best solar savings, as Entergy will purchase your excess solar energy. Keep in mind, it will be at the solar buyback rate, which is lower than the retail rate of electricity. This rate varies depending on the season.  

    With Option 3, Entergy will purchase all of the electricity your solar panels produce at that same solar buyback rate, which results in slightly lower savings than if you went with Option 2.

    For more information about going solar with Entergy, check out our in-depth guide here.

    Table 8. Entergy Texas’ solar buyback plans
    Utility Plan Import rate per kWh* Solar buyback rate
    Entergy Net Metering Option 1 $0.10 $0
    Entergy Net Metering Option 2 $0.10 $0.04 - $0.05
    Entergy Net Metering Option 3 $0.10 $0.04 - $0.05

    Should Texans consider solar batteries?

    So, we know that most Texas homeowners don’t have access to a true net metering program, in which all solar energy is credited at the full-retail rate of electricity. Does that mean homeowners should get solar batteries to save extra money on their utility bills?

    From a financial standpoint, solar batteries will technically save you additional money on your electricity bills. Instead of sending your excess energy to the grid and getting paid at a less-than-retail rate, you would store the energy in your battery and use it later, thus making all of your electricity worth the full price. 

    However, batteries are pretty expensive, around $10,000 at a minimum, so the amount of extra savings you’ll get probably won’t pay off your battery system, even with the federal solar tax credit.

    With that said, you have to consider the other benefits of buying a solar battery, besides the extra savings you may or may not see. For one, solar batteries let homeowners greatly decrease their independence on the grid. You don’t have to pay the utility as much money and you get to use electricity that you produced right on your roof. Plus, it maximizes the amount of clean energy your home uses. 

    Perhaps the biggest selling point of solar-plus-battery storage is that you get to keep your power on during an outage. Having access to reliable backup power is a huge concern for Americans across the board, but for Texans especially. 

    Winter storms in recent years have caused prolonged blackouts because Texas’ utilities simply aren’t equipped to handle such low temperatures. A solar battery can give Texas homeowners peace of mind in these situations, which, for many, is priceless. If you're curious about solar batteries, our solar calculator gives you the option to see how a solar battery will impact your investment. 

    Are solar panels worth it in Texas?

    There’s a reason why Texas’ solar energy industry is growing so quickly, and it’s not because people like spending tens of thousands of dollars for fun. It’s because installing a solar energy system can be a worthwhile investment for many Texans, and it's ultimately up to you how worth it it is.

    Sure, everyone would like it if their REP or utility purchased their excess solar energy at the full-retail rate, but that’s just not the case. That doesn't mean you shouldn’t go solar, though. Installing solar panels, even just enough to cover a majority of your energy usage instead of all of it, can save you hundreds of dollars a month. In fact, many Texas homeowners can recoup their investment in their solar panels in as little as 12 years! 

    And it’s not just about the energy bill savings - switching to solar gives you the ability to generate your own renewable energy, right on your own roof. Why wouldn't you want to save money on your electricity bill while taking your energy freedom back from big companies?

    It’s all about smart planning, picking the right REP (if you can), and working with the right installer. You can start your solar journey by using our state-of-the-art solar calculator, which will give you an idea of what kind of solar savings you can expect, based on your location and your most recent electricity bill.
