💡 Accountant's Note
Most regulated utilities have a Fuel Cost Adjustment (FCA) or Energy Cost Adjustment (ECA) clause that allows periodic (monthly, quarterly, or annual) adjustment of rates to reflect actual fuel cost changes without a full rate case. The clause includes a 'true-up' mechanism: if actual fuel costs are lower than the forecast used to set the FCA rate, the over-collection is tracked as a regulatory liability and refunded to customers in the next adjustment period. This prevents utilities from profiting from favorable fuel cost variances — regulators pass all fuel savings and costs directly to customers.
Practitioner & Systems Framework
💻 ERP Architecture
Track FCA collections separately from base rate revenue. The FCA regulatory liability or asset is the running balance between actual fuel costs incurred and amounts collected through the FCA rider. Many utilities calculate this balance monthly and report it to the PUC in monthly FCA compliance filings. The balance is carried on the balance sheet until cleared through rate adjustments.
⚠️ Audit Flags
Auditors verify the FCA mechanism calculation against the tariff provisions and PUC orders. The fuel cost basis (what costs are includable in the FCA — typically natural gas at spot or contract prices, purchased power, coal, nuclear fuel) must match the tariff definition exactly. Costs outside the defined fuel categories must not be included in the FCA.
