💡 Accountant's Note
When regulated utility plant is retired, the accounting is distinctly different from commercial fixed asset disposal. Under FERC accounting (ASC 980 + FERC USoA): (1) The gross original cost is removed, (2) Accumulated depreciation is reversed, (3) Removal costs are recorded as actual costs incurred, (4) Salvage proceeds are credited. The net of these items flows to the 'Cost of Removal' account — which for regulated utilities flows to a Regulatory Liability rather than income. This is because regulated depreciation rates include a component for future removal costs — these charges have been collected from customers over years and must be returned through lower future rates.
Practitioner & Systems Framework
💻 ERP Architecture
FERC Account 108 (Accumulated Provision for Depreciation) absorbs retirements. The cost of removal and salvage flow through a net cost of removal regulatory account. Many utilities carry a large Regulatory Liability for 'accumulated cost of removal' representing decades of depreciation charges collected from customers for net removal costs not yet incurred. This is one of the most common regulatory liabilities on utility balance sheets.
⚠️ Audit Flags
Auditors test plant retirements against capital project closeout records. Items removed from plant in service without retirement accounting overstate plant and accumulated depreciation. The cost of removal regulatory liability amortization (as actual net removal costs are incurred) must be tracked. Coal plant early retirements require assessment of stranded cost regulatory asset treatment for un-depreciated book value.
📄 Required Documentation
Plant retirement work orders, salvage sale documentation, contractor invoices for removal, FERC account reconciliation, accumulated cost of removal regulatory liability roll-forward, PUC approval for any regulatory treatment of early retirements.
