Standard Choice Offer (SCO): Understanding Your Default Gas Rate

Learn How Ohio’s Default Natural Gas Rate Works and Whether It’s the Right Choice for Your Home

Key Takeaways

  • The Standard Choice Offer (SCO) is the default natural gas rate in Ohio for eligible customers who haven’t chosen a specific supplier.
  • Your monthly rate is calculated using the NYMEX market price plus a Retail Price Adjustment, meaning it changes every month based on demand.
  • While the SCO guarantees a market-based price, switching to a Retail Choice plan or government aggregation program can provide more predictable bills and eco-conscious options.

If you live in Ohio and use natural gas, you’ve probably noticed the term “Standard Choice Offer” or “SCO” on your monthly bill. For many residents — especially those served by Columbia Gas of Ohio or Enbridge (formerly Dominion East Ohio) — the SCO serves as the default setting for natural gas supply. It isn’t a penalty or a hidden fee. It’s a regulated, market-based rate assigned automatically because you haven’t actively selected an independent energy supplier or joined a local aggregation initiative. Understanding how this pricing works and utilizing tools like the state’s comparison chart can help you decide whether to stick with the default or shop around for a plan offering better stability. We’ll walk you through when it makes sense to stay on the SCO and when exploring a fixed-rate retail plan might be a smarter financial move.

What Is the Standard Choice Offer (SCO)?

The Standard Choice Offer (SCO) is the default natural gas rate for eligible Ohio residents who have not chosen an alternative supplier. It ensures you have uninterrupted access to a reliable supply of natural gas at a fair, regulated price. Unlike a fixed-rate plan where you pay the exact same amount per unit of gas for a year or more, the SCO is a variable rate that fluctuates monthly based on national energy trends.

It is crucial to know that your local distribution company — such as Columbia Gas of Ohio or Enbridge — still physically delivers the natural gas to your home, maintains the pipelines, reads your meter, and handles all emergency calls regardless of your SCO status. The SCO strictly dictates the rate you pay for the gas supply itself, not the delivery infrastructure. Heavily overseen by the Public Utilities Commission of Ohio (PUCO), its primary goal is to pass the true commodity cost of gas through to you without unauthorized markups. If you are a new homeowner setting up utilities in a participating service area, you are typically placed on this rate automatically after a brief introductory period.

Even if you are on the SCO, you might see a specific company name (like Direct Energy or AEP Energy) listed as your supplier on your bill. This is because these companies win “bids” to service SCO customers, but they must charge you the regulated SCO rate, not their own retail rate.

How the Standard Choice Offer Is Calculated

Your monthly SCO rate is determined by adding the wholesale NYMEX market price and a retail price adjustment.

One of the biggest advantages of the Standard Choice Offer is its structural transparency. While the price changes monthly, the formula used to set that price is public and thoroughly regulated. Understanding this calculation provides a clear window into the national energy market and helps clarify why your bill spikes in the winter or drops during the summer.

To figure out what you are paying, you can look at this simple equation:

SCO = NYMEX month-end settlement price + Retail price adjustment

  • NYMEX month-end settlement price: This is the wholesale cost of natural gas on the national market (the New York Mercantile Exchange). It reflects the raw cost of the fuel and surges naturally when winter weather drives up demand.
  • Retail price adjustment: This covers the chosen supplier’s administrative costs and risks for the year. Because it is set through competitive bidding, this service fee stays relatively stable for the entire year.

Importantly, your local utility company does not profit from the SCO supply rate. It is a direct pass-through cost, meaning you pay exactly what it costs the supplier to secure the gas on the wholesale market plus that approved adjustment. This structure protects you from arbitrary price gouging on the commodity itself.

Natural Gas Supplier Vs. Delivery Utility

Understanding the difference between a natural gas supplier vs. delivery utility is essential for reading your bill correctly and recognizing where your money goes each month. While one company procures your fuel, a completely separate entity maintains the physical infrastructure.

SCO Vs. Retail Choice Vs. Government Aggregation

When setting up utilities, you face a common decision: Should you stay on the standard default rate, switch to a retail supplier, or join a local aggregation program? There is no single “right” answer. You can explore more about the differences between fixed and variable rates or the benefits of flat rate natural gas plans to help inform your decision, as it depends entirely on your budget, risk tolerance, and personal sustainability goals.

Plan TypeRate Structure (Variable/Fixed)How to Enroll
Standard Choice Offer (SCO)Variable (Changes Monthly)Automatic default if you take no action.
Retail ChoiceMostly Fixed (can be Variable)Shop and enroll through the Energy Choice Ohio website.
Government Aggregation ProgramTypically Fixed (Community Rate)Automatic if your community passes a ballot measure (opt-out available).

Retail choice allows you to proactively shop for an environmentally mindful supplier to find terms that fit your life, helping you implement everyday sustainable living tips. Alternatively, an aggregation program offers an excellent middle ground, providing budget stability without requiring you to comb through individual plans on your own.

How the Annual SCO Auction Works

Every year, the PUCO standard choice offer retail price adjustment is determined by an annual competitive auction overseen by the state. Certified retail natural gas suppliers submit bids to secure the right to service SCO customers. This rigorous bidding process ensures the Ohio standard choice offer remains a dependable, market-based price that protects residents from unnecessary overhead fees.

How to Find the SCO on Your Gas Bill

If you want to evaluate your current energy strategy, you first need to know exactly what you are paying. Finding your SCO gas rate and your assigned default supplier is a straightforward process:

  1. Locate your most recent utility bill, either via your online portal or your printed paper statement.
  2. Look for the “Supply Charges” or “Gas Cost” section, which is typically found on the second page of your billing breakdown.
  3. Identify the named supplier and check the price listed per Ccf (or Mcf) to confirm your exact rate for that specific billing cycle.

You can also check the natural gas section of the Public Utilities Commission of Ohio (PUCO) website to verify seasonal trends before making a switch.

Evaluating Your Energy Strategy

Choosing between an SCO or a fixed-rate plan depends on whether you prioritize market flexibility or budget predictability.

Deciding between the default rate, a retail supplier, and a community initiative ultimately comes down to how much you value bill predictability versus market flexibility. Here is a quick checklist to help you evaluate your current setup:

  • Stay on the SCO if: You prefer a hands-off approach and don’t mind your bill fluctuating with the seasons. It’s a safe bet if you want to pay the true market price for the gas commodity without worrying about early termination fees or long-term contracts.
  • Use Energy Choice Ohio if: You are managing a strict household budget and want to avoid winter price shock. By leveraging the state’s Apples to Apples comparison chart, you can proactively shop for a fixed-rate retail plan that locks in your pricing for 12 to 36 months, allowing you to opt for eco-conscious suppliers.
  • Join a government aggregation program if: Your local community has successfully negotiated a competitive bulk rate and you want the benefits of a fixed price without having to research and vet individual plans yourself.

Frequently Asked Questions About the Standard Choice Offer

Is the Standard Choice Offer a fixed or variable rate?

The Standard Choice Offer is a variable rate. It changes every single month based on the closing price of natural gas on the New York Mercantile Exchange (NYMEX) plus a set retail price adjustment approved by state regulators.

Does the Standard Choice Offer include my delivery charges?

No, the Standard Choice Offer only covers the cost of the natural gas supply itself. Your utility bill will still include separate delivery charges from your local distribution company, which cover the physical costs of pipeline maintenance and meter reading.

How do I switch from the Standard Choice Offer to a fixed rate?

To switch, visit the Energy Choice Ohio website and use the Apples to Apples comparison chart to review available fixed-rate plans. Once you select a certified retail supplier and sign a contract, they will notify your local utility, and the switch will happen automatically within a few billing cycles.

Is the Standard Choice Offer usually cheaper than a fixed-rate plan?

It completely depends on current market conditions. Sometimes the variable SCO rate is significantly lower than available fixed-rate offers, particularly when gas prices drop in the spring and summer. However, during periods of high winter demand or global volatility, the SCO rate can easily exceed fixed rates. We always recommend comparing current fixed offers to the recent SCO history to decide what fits your risk tolerance.

Can I cancel the Standard Choice Offer at any time?

Yes, you can leave the Standard Choice Offer at any time without paying an early termination fee. You simply need to enroll with a competitive retail supplier or join a government aggregation program. Once your new enrollment is fully processed, you will be switched off the SCO automatically.

Why is there a supplier name on my bill if I’m on the SCO?

You might see a company like Direct Energy, AEP Energy, or Interstate Gas Supply listed on your bill even if you are on the default rate. These companies participate in a PUCO auction to secure the right to service SCO customers. Despite their brand name appearing on your statement, they are required by law to charge you the strictly regulated SCO rate, not their private retail rates.

Does the SCO include carbon offsets or renewable gas?

Generally, no. The Standard Choice Offer is based strictly on the standard natural gas mix available in the pipeline system. If sustainability is a major priority for your household, you will need to switch to a retail supplier that specifically offers carbon-neutral gas or verifiable carbon offset programs.
