Nextera Energy Resources LLC v. Iowa Utilities Board
2012 Iowa Sup. LEXIS 62
Iowa2012Background
- MidAmerican filed for advance ratemaking principles for Wind VII (up to 1001 MW) in 2009; NextEra intervened objecting to ratemaking principles for MidAmerican's Wind VII.
- MidAmerican is a rate-regulated utility serving retail customers; Wind VII would also be sold in wholesale markets; stipulation with Office of Consumer Advocate addressed twelve ratemaking principles and conditions precedent.
- Board granted advance ratemaking principles; NextEra sought judicial review; district court affirmed the Board.
- NextEra argued the Board misapplied 476.53(4)(c)(2) 'need' and failed to require comparisons with other feasible alternatives; argued potential equal protection and Commerce Clause issues.
- The Iowa Supreme Court upheld the Board's interpretation of 476.53, rejected 476.43 applicability, and held no constitutional violations; majority affirmed district court.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| How should 'need' be interpreted in 476.53(4)(c)(2)? | NextEra: Board misread 'need' as broader than present capacity. | MidAmerican: Board properly includes future environmental compliance, fuel diversity, costs, etc. | Board correctly construed 'need' to include broader factors. |
| Whether the Board correctly treated 'other feasible alternative sources' under 476.53(4)(c)(2)? | NextEra: require same-type wind comparisons and pre-application negotiations; otherwise restrict competition. | MidAmerican: statute allows cross-type comparisons; comparison before ratemaking principles is not required. | Board properly allowed comparison with other feasible (including non-wind) sources prior to ratemaking principles. |
| Is Iowa Code section 476.43 applicable to MidAmerican’s application? | NextEra: section 476.43 should apply to prevent discrimination against alternate energy producers. | MidAmerican: 476.44 exempts utilities exceeding 105 MW of alternative-energy capacity from 476.43. | 476.43 not applicable; MidAmerican exempt from 476.43 due to >105 MW of wind capacity. |
| Does applying 476.53 to a rate-regulated utility that competes in the wholesale market violate Equal Protection or the Commerce Clause? | NextEra: subsidizing wholesale market competition violates equal protection and burdens interstate commerce. | MidAmerican: rational-basis review; state has legitimate interests; burden on interstate commerce minimal; no violation. | No equal protection or Commerce Clause violation; rational-basis justification upheld. |
