Key Takeaways

  • Community choice aggregation (CCA) is a local energy program that lets a city or county buy electricity supply for its residents.
  • Your traditional utility company still delivers the electricity and maintains the power lines, even if your power is generated through a CCA.
  • Customers in many programs are automatically enrolled, but you can typically opt out and return to your utility’s default supply option.

Community choice aggregation is a local energy program that lets a city, county, or municipality buy electricity supply for residents and businesses while the regular utility still delivers the power. If you recently received a confusing letter in the mail about an automatic utility enrollment or noticed an unfamiliar supply fee on your latest electricity bill, you aren’t alone. It’s reasonable to pause when a new electricity supplier or supply charge shows up on your bill. So, exactly what is community choice aggregation? We’re here to help you unpack this program and decide if staying enrolled makes sense for your new home.

How Does a CCA Energy Program Work?

CCA programs enable communities to leverage combined purchasing power to secure cleaner energy sources or stabilize long-term rates.

At its core, this program allows local cities, counties, or municipalities to pool the electric demand of their communities together to buy power in bulk. By leveraging the combined purchasing power of thousands of residents, local governments may be able to negotiate competitive energy contracts on your behalf. The primary goals behind these programs typically involve securing a higher percentage of renewable energy โ€” like solar or wind โ€” or stabilizing long-term energy rates for the entire community. Community choice aggregation is only available in certain states and municipalities. If you’re moving, don’t assume your new address has a CCA program. You can check your city or county website, your state public utility commission, or your electric bill’s supply section.

๐ŸŒฑ Eco Edge: Many CCA programs offer a higher renewable energy mix than the default utility supply. Check your program’s power content label or renewable disclosure to see what you’re actually buying.

Instead of relying only on the utility’s default supply option, your local government may choose a supply contract for participating customers. When officials buy in bulk, they often gain access to cleaner power sources that might be too expensive for individual homeowners to procure on their own. If you want to dive deeper into how different municipalities implement these models, you can read the specifics according to the EPA’s Green Power Partnership.

Community Choice Aggregation vs. Utility Service

While a Community Choice Aggregation (CCA) buys the electricity supply, your local utility still delivers the power, manages billing, and repairs infrastructure.

Understanding the difference between a CCA and your utility can make the whole setup feel less confusing. The distinction comes down to generation versus transmission. The CCA buys the electricity supply, while your utility delivers it to your home.

Your local utility still owns the physical infrastructure, handles all the monthly billing, and dispatches service trucks to fix power outages. They simply distribute the power that your municipality purchased. You can read an excellent breakdown from the U.S. Energy Information Administration to understand exactly how electricity is generated, transmitted, and distributed to consumers, ensuring you never have to worry about losing your connection just because your supplier changed.

How to Compare CCA Rates on Your Electric Bill

To check for savings, find your CCA and utility supply rates, multiply each by your monthly kWh usage, and compare the supply costs directly.

To determine if you’re actually saving money, you need to compare the CCA’s specific generation rate against your legacy utility’s default supply rate. Start by digging up your most recent electricity statement. You won’t receive two separate bills in the mail. Instead, you’ll still get one consolidated bill directly from your primary utility provider. The CCA supply charge usually replaces the utility’s default generation or supply charge. Your transmission and delivery fees remain unchanged.

For example, if your CCA supply rate is 10 cents per kWh and you use 800 kWh in a month, your supply cost would be about $80. If your utility’s default supply rate is 11 cents per kWh, the same usage would cost about $88 before taxes and delivery charges. Here is a simple step-by-step process to check your rates:

  1. Find your CCA supply or generation rate on your bill.
  2. Find your utility’s current default supply rate on the utility website or state comparison site.
  3. Multiply each rate by your monthly kWh usage.
  4. Compare the monthly supply cost, not the total bill.
  5. Factor in renewable energy content, contract length, and any program fees.
Bill ItemWhat to CheckWhy It Matters

Should You Opt Out of Community Choice Aggregation?

Deciding whether to opt out of community choice aggregation depends on your priorities for cost savings versus supporting renewable energy.

Deciding whether to opt out of community choice aggregation ultimately comes down to your personal household budgeting and energy priorities. Customers in many CCA programs are automatically enrolled, but you can typically opt out and return to your utility’s default supply option. Check your local CCA notice for deadlines, fees, and re-enrollment rules.

๐Ÿ’ธ Money-Saver: Before you opt out, review your CCA notice or program website for the timing rules. Many programs allow no-cost opt-out, but deadlines and re-enrollment rules can vary.

If your local government secured a competitive bulk rate, staying enrolled is an easy way to support sustainable energy while keeping costs low. However, if the municipal rate creeps higher than the standard utility option, you can usually opt out, but you’ll want to check your local program’s timing rules first. Taking a few minutes to crunch those numbers is a vital part of managing your electric services effectively in your new home.

When Staying Enrolled Makes Sense

  • The CCA rate is equal to or lower than the utility default rate.
  • You want a higher renewable energy mix.
  • The program has transparent terms and no confusing fees.
  • Your city or county reinvests revenue into local energy programs.

When Opting Out May Make Sense

  • The CCA rate is consistently higher than the utility default rate.
  • You prefer your utility’s standard supply option.
  • You’re on a special utility rate plan and want to avoid billing confusion.
  • You don’t understand the contract terms after reviewing the notice.

Frequently Asked Questions About Community Choice Aggregation

Still sorting out whether your CCA notice is a good thing or a headache waiting to happen? These quick answers cover the most common questions homeowners and renters have when a community choice energy program shows up on their bill.

Is community choice energy mandatory?

While enrollment is often automatic due to state laws dictating an opt-out model, your active participation is never mandatory. You always retain the legal right to decline community choice energy and return to your legacy provider. A simple phone call or online form is usually all it takes to switch back.

Will my power reliability change with a CCA?

No, your power reliability won’t change at all. Your legacy utility company still maintains the physical grid, meaning your outage response, line maintenance, and electricity delivery still come from the same utility. You receive the same continuous flow of electricity regardless of who generates it.

How do I know if I live in a CCA service area?

The easiest method is to look at the supply section of your most recent electricity bill to see if a municipal aggregator is listed as the supplier. You can also check your local city or county government website, as they routinely post public notices regarding active bulk energy programs. Additionally, state agencies like the California Public Utilities Commission offer resources to check availability in specific regions.

Who do I call during a power outage?

In the event of an outage, you must call your traditional utility company to report the issue, not the CCA. The legacy utility still owns the poles, wires, and transformers, making them fully responsible for dispatching repair crews and restoring your service safely.

Does a CCA charge extra fees?

A municipal energy program replaces the generation charge on your bill; it isn’t an additional duplicate fee tacked on top of your normal charges. However, the specific rate you pay for that generation may be slightly higher or lower compared to the standard utility rate.

Can a renter participate in a CCA program?

Usually yes, if the electric account is in the renter’s name and the address is in a participating service area. If utilities are included in rent, the property owner or manager may control the account.

Is community choice aggregation the same as choosing a retail electric supplier?

Not exactly. A CCA is organized by a local government for eligible customers in a community, while a retail electric supplier is typically chosen individually by the customer in a competitive energy market.

Can I choose a greener CCA plan?

Many CCA programs offer different supply tiers, including standard renewable content and 100% renewable options. Availability and pricing vary by program.
