Delinquency by Design: How Unpaid Bills Re-enter the Rate Base

When a household falls behind on its electricity bill, the immediate consequence is a shutoff notice. The longer-term consequence is less visible but more pervasive: the unpaid balance becomes a cost that regulators and utilities must allocate somewhere. In most U.S. jurisdictions, that somewhere is the remaining customer base. The mechanism is not hidden, but it is rarely explained at the kitchen table. Understanding how uncollectibles move through the ratemaking process is essential for consumers comparing retail offers and for regulators weighing the equity effects of rate design.

The Anatomy of an Uncollectible

Utilities do not absorb written-off accounts as a charitable gesture. When a customer’s debt is deemed unrecoverable—after collection efforts and any available assistance programs—the utility records it as an uncollectible expense. In regulated markets, that expense typically enters the revenue requirement during the next rate case. Commissioners review historical write-offs and may approve a forecast of future bad debt, which is then spread across all rate classes. The result is a modest but persistent surcharge embedded in the base rate.

In states with retail choice, the pathway differs but the destination is similar. Competitive retailers build bad-debt costs into their offers, and the incumbent utility—still responsible for delivery—recovers uncollectibles through a delivery charge. Some states allow explicit bad-debt riders that adjust annually, separating the cost from the general rate case. Either way, the paying customer funds the shortfall.

Moratoriums and the Arrears Cliff

The pandemic-era shutoff moratoriums brought the issue into sharp relief. States and utilities paused disconnections for months, allowing arrears to accumulate. When moratoriums lifted, many households faced balances far beyond their monthly ability to pay. Utilities responded with installment plans and expanded assistance, but the underlying cost did not disappear. In California, for example, the California Public Utilities Commission approved a sweeping arrearage relief program funded through a combination of federal dollars and a charge on ratepayers. In Illinois, the General Assembly created the Utility Emergency Repair Fund, financed in part by a small surcharge on gas and electric bills. These are explicit acknowledgments that unpaid bills are a shared liability.

State-Level Variation in Recovery

The methods vary considerably. Texas, with its competitive retail market, allows transmission and distribution utilities to recover uncollectibles through a dedicated rider reviewed annually by the Public Utility Commission. The rider appears as a separate line item on delivery charges. Pennsylvania’s universal service programs, funded by a gross receipts tax and a rider, provide low-income assistance while also recovering uncollectibles from all customers. New York’s regulated utilities include bad-debt expense in base rates, subject to reconciliation in rate cases. Each approach reflects a different balance between transparency, administrative cost, and political acceptability.

For consumers comparing electricity providers, the implication is straightforward: the advertised rate per kilowatt-hour is not the only cost signal. In regulated states, bad-debt recovery is baked into the tariff. In competitive markets, retailers may absorb some bad debt but typically pass it through in the form of higher prices for all customers or stricter credit requirements that shift risk to those with weaker credit histories. A plan with a low headline rate may still carry a higher effective cost if the provider’s customer base includes a larger share of delinquent accounts.

The Regulator’s Dilemma

Rate commissioners face a difficult trade-off. Aggressive recovery of uncollectibles ensures that utilities remain whole and that investors are not penalized for social policy choices. But shifting costs to paying customers can create a regressive burden, especially when the underlying cause of nonpayment is affordability, not avoidance. Some commissions have experimented with alternative rate designs—such as percentage-of-income payment plans or fixed charges that more closely track fixed costs—to reduce the cycle of arrears and write-offs. Others have expanded weatherization and bill assistance to address the root cause.

Practical Implications for Consumers

The next time a utility bill includes a line item labeled “bad debt” or “uncollectibles,” it is not an error. It is the visible tip of a cost-allocation system that every jurisdiction operates. Consumers shopping for electricity in competitive markets should ask whether a provider’s offer includes explicit bad-debt recovery or whether the delivery utility’s rider will apply regardless of the supplier. Businesses with multiple meters should review their tariff schedules for uncollectibles charges, which can vary by rate class. And regulators reviewing rate design should consider whether the current method of recovering uncollectibles aligns with broader affordability goals—or whether it simply recycles the problem into the next billing cycle.

The quiet surcharge for unpaid power bills is not going away. But understanding its mechanics is the first step toward a more informed discussion about who pays, how much, and whether the system can be designed to be both solvent and fair.
