345 S.W.3d 60
Tex.2011Background
- AEP Texas Central Co. and CPL Retail Energy initiated a Section 39.262 true-up proceeding to finalize stranded costs and related true-up amounts.
- The PUC issued a final order determining market value, NBV, and a capacity auction true-up under Chapter 39 of PURA; Consumers intervened.
- Market value could be determined under several methods; Subsection (i) requires the ECOM model for remaining nuclear assets unless other methods apply.
- AEP elected the sale of assets method (h(1)) after selling its STP generation assets; Consumers argued ECOM or other methods should be used for nuclear assets.
- The PUC allowed sale of assets method for nuclear assets but left open NBV adjustments for commercially unreasonable conduct.
- The court of appeals remanded on several NBV adjustments, and the Supreme Court granted review to resolve method selection, NBV adjustments, capacity auction true-up, and interest.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Proper valuation method for nuclear assets | Consumers: ECOM required for nuclear assets after sale; sale method not permitted. | AEP: sale of assets method valid for market value; Subsection (i) backups only; PUC reasonable. | Sale of assets method permissible for market value; Subsection (i) backup not mandatory. |
| NBV adjustments for commercially unreasonable conduct | Consumers: NBV adjustments were insufficient or improper. | PUC validly adjusted NBV for commercially unreasonable conduct under 39.252(d). | NBV adjustments for commercially unreasonable conduct are permitted and sustained. |
| Capacity auction true-up basis | True-up must be based on actual prices from 39.153 capacity auctions, not proxy prices. | PUC used a proxy; issue not properly remanded previously. | Remand to recalculate capacity auction true-up using actual auction prices per State v. PUC. |
| Interest on stranded costs | CenterPoint invalidated Rule 25.263(0)(3) start date; rate may be valid. | PUC correctly applied Rule 25.263(0)(3) with a modified start date. | Interest on stranded costs properly calculated with the modified start date. |
| Bridge power sales and tax gross-ups | Arguments about bridging profits and tax gross-ups affecting NBV and stranded costs. | PUC's treatment supported by evidence; bridge sales not mandated; gross-ups justified. | Bridge power sales not required; gross-ups upheld to avoid windfall. |
