The Enrollment You Didn't Request: How to Audit a Municipal Aggregation Contract in 2026

Municipal aggregation is one of the quieter ways American households buy electricity. A city or town negotiates a supply contract on behalf of residents, and most households are enrolled automatically unless they affirmatively opt out. The arrangement is not a scam, and it is not a guarantee of savings. It is a default, and defaults deserve scrutiny. As of November 2026, with many aggregation contracts approaching renewal, the practical question for residents is not whether bulk buying sounds sensible. It is whether the specific rate, term, and exit terms on the table beat the alternatives available to your household.

How Opt-Out Aggregation Actually Works

In states that permit municipal aggregation, a local government or its consultant runs a procurement process and selects a competitive electricity supplier. The utility still delivers power, maintains the wires, and typically sends the bill. What changes is the supply portion: the generation and related charges that appear on the bill. Residents in the participating jurisdiction are enrolled by default, usually after a notice period and an opt-out window. If a household does nothing, it stays in the program.

That structure is efficient for the municipality, because high participation gives it buying leverage. It also shifts the burden of vigilance to the household. A resident who ignores the mailer, misses the public meeting, or moves into town after the enrollment window may end up on a rate that is neither the cheapest nor the most suitable. Opt-out aggregation can be a useful consumer tool, but only when residents treat enrollment as a decision rather than a formality.

The Three Prices You Need on One Sheet

A meaningful comparison requires three supply prices, not one: the town's contracted rate, the utility's default service rate, and at least one competitive retail offer available to your address. The town rate is usually fixed for a stated term, though some programs include variable components or seasonal adjustments. Utility default service may change on a schedule set by regulators, so the relevant figure is the projected default rate for the months you will actually be enrolled. Retail offers vary widely and often include introductory pricing.

Use your annual kilowatt-hour usage, not a single month, and compare the all-in supply price per kWh. If the town rate is 10.8 cents and default service is projected at 11.4 cents, the headline difference is 0.6 cents per kWh. At 700 kWh per month, that is about $4.20 monthly, or roughly $50 annually, before any fees. That is real money, but it is not a windfall, and it can disappear if the town contract carries a monthly administrative charge or an early termination fee that the default service does not.

Item to compare	Town aggregation	Utility default service	Retail offer
Supply price per kWh	Fixed or variable?	Projected schedule	Introductory or standard?
Term length	Months or years	Month to month	Contract term
Monthly fee	Often none, but check	Typically none	Sometimes present
Exit fee	May apply after opt-out window	Usually none	Common
Renewable content	State-specific disclosure	State portfolio standard	Contract-specific

Delivery charges generally remain the same regardless of supplier, so savings and losses concentrate in the supply line. A town rate that looks competitive against default service may still lose to a well-priced retail offer, and a retail offer that looks cheap may carry a fee or a renewal rate that changes the math.

Fine Print: Fees, Terms, and the Renewal Trap

Aggregation contracts are public documents in many jurisdictions, but residents seldom read them. The provisions that matter most are term length, renewal mechanics, opt-out procedures, and fees. Look for whether the contract renews automatically, whether the renewal rate is disclosed in advance, and whether the municipality must re-bid or may extend with the incumbent supplier. A program that saved money in its first term can become expensive in its second if the renewal rate is set under a different market condition.

Check for early termination fees, monthly administrative charges, minimum usage requirements, and any variable-rate triggers. Confirm the renewable energy attributes being purchased and whether the program's green claim rests on renewable energy certificates that are separated from the actual electrons. Ask who is compensated in the transaction. Some municipalities use aggregation consultants or brokers, and their fees may be embedded in the supply rate rather than billed separately. That is not improper, but residents should know it exists.

Also verify the supplier's license status and complaint record in your state. Aggregation programs can fail or transfer, and the fallback is usually a return to utility default service. A household should know how that return works, whether it can happen mid-term, and whether any fee applies.

Questions to Ask Before a 2026 Renewal

A renewal is the right moment to test the program rather than accept it. Ask the municipality or program administrator for the new rate, the term, and the effective date. Ask whether the rate is fixed or variable and what portion of the price is subject to change. Ask for the opt-out deadline, the method for opting out, and whether an exit fee applies after that date. Ask whether renewal is automatic and whether residents receive individualized notice.

Residents should also ask how the new rate compares with the utility's projected default service rate, not merely with the old aggregation rate. Ask what renewable attributes are included, who the supplier is, and how the municipality selected it. Ask whether the consultant or broker is paid by the supplier and whether that compensation is disclosed. Ask what happens if the supplier exits the market or fails to perform. Finally, ask whether the program includes any low-income assistance, budget-billing coordination, or customer-service commitment that a resident would lose by opting out.

A Practical Audit Routine

Start with a recent bill and identify the supply charge and your annual usage. Obtain the town contract summary, the utility's default service tariff or projected rate, and two current retail offers for your address. Put the all-in supply prices, fees, and terms on one page. Set a calendar reminder for the opt-out window, and keep copies of the notices you receive. Households that move should confirm whether enrollment follows the address or the account. Households on budget billing should verify how the supply change affects the monthly payment.

The sensible conclusion is not that aggregation is good or bad. It is that automatic enrollment is a convenience, not a verdict. A town's bulk purchase can be the best available option for many residents, but it cannot be assumed to be the best for every load profile. The household that checks the rate, reads the exit terms, and asks about renewal before the deadline is the one that turns a default into an informed choice.
