Rate-Regulated Accounting - Regulatory Asset (Deferred Cost Recovery)
Deferring an operating cost that would normally be expensed immediately, because the regulator has ordered or is probable to allow recovery through future rates — creating a regulatory asset under ASC 980.
Regulatory Asset - Amortization Over Authorized Recovery Period
Recording the systematic amortization of a regulatory asset into expense as recovery is achieved through customer rates, over the period authorized by the public utility commission.
Regulatory Liability - Over-Collection from Customers (Refund Obligation)
Recording a regulatory liability when the utility has collected more from customers than its authorized revenue requirement, creating an obligation to refund or credit customers in future periods.
Regulatory Disallowance - Write-Off of Regulatory Asset Denied by Regulator
Writing off a regulatory asset when the public utility commission denies recovery, ruling that the costs are imprudent, excessive, or not in the public interest — a potentially catastrophic earnings event.
Rate Case Filing Costs - Deferred as Regulatory Asset
Capitalizing the legal, consulting, and expert witness costs of filing a general rate case as a regulatory asset, amortized over the rate case period upon PUC approval of the new rates.
Pension / OPEB Regulatory Asset - Deferred Under ASC 980 vs. ASC 715
Recording the portion of unrecognized pension and OPEB costs (that would be charged to OCI under ASC 715) as a regulatory asset instead, because the PUC allows recovery of pension costs through future rates.
Stranded Cost Regulatory Asset - Deregulation Transition Costs
Recording stranded costs as a regulatory asset when a utility transitions from regulated monopoly to competitive markets, representing assets and costs that are no longer recoverable through market prices.
Revenue Decoupling Mechanism - Adjustment for Sales Volume Variance
Recording the decoupling adjustment to revenue where the utility's authorized revenue requirement is independent of actual sales volumes, preventing utility earnings from varying with conservation.
Utility Acquisition Premium - Regulatory Asset for Goodwill Recovery
Recording the acquisition premium paid above book value for a regulated utility as a regulatory asset when the PUC has authorized its recovery through future rates, rather than immediate write-off to goodwill.
Retail Electric Revenue - Cycle Billing to Residential & Commercial Customers

Unbilled Revenue Accrual - Electricity Delivered But Not Yet Billed (Cycle Billing)
Accruing revenue for electricity delivered between the last meter reading date and fiscal period-end, representing usage that has occurred but will not be billed until the next meter reading cycle.
Fuel Cost Adjustment (FCA) / Fuel Adjustment Clause - Over-Collection Regulatory Liability
Recording the over-collection of fuel costs from customers through the Fuel Cost Adjustment (FCA) rider when actual fuel costs were lower than the forecast embedded in current rates, creating a regulatory liability.
Fuel Cost Adjustment - Under-Collection Regulatory Asset (Fuel Costs Exceeded Forecast)
Recording a regulatory asset when actual fuel costs exceed the amounts collected from customers through the Fuel Cost Adjustment rider, creating a deferred cost to be recovered through future rate increases.
Wholesale Power Sales - FERC-Regulated Market Revenue
Recording revenue from wholesale electricity sales in organized wholesale markets (PJM, MISO, CAISO, SPP) at market clearing prices, recognized at the time of delivery.

Purchased Power Expense - Power Purchase Agreement (PPA) Cost
Recording the cost of purchasing electricity from independent generators under long-term Power Purchase Agreements (PPAs), recognized as electricity is delivered.
Emission Allowances - SO2 / NOx Cap-and-Trade (EPA Clean Air Act)
Recording the purchase of sulfur dioxide (SO2) and nitrogen oxide (NOx) emission allowances required under EPA's cap-and-trade programs, and their consumption as generation occurs.

ARO Accretion Expense - Annual Increase in Nuclear Decommissioning Obligation
Recording the annual accretion of the Asset Retirement Obligation as the decommissioning date approaches, increasing the liability as time passes and the discount unwinds.
Nuclear Decommissioning Trust Fund - Contributions and Investment Returns
Recording contributions to the externally-managed Nuclear Decommissioning Trust Fund and the recognition of investment returns within the trust, which offsets the ARO liability over time.
Plant Retirement - Removal from Service, Net Book Value Write-Off
