Colstrip Energy Ltd. Partnership v. Northwestern Corp.
253 P.3d 870
Mont.2011Background
- CELP owns a Rosebud County electrical generating plant; Northwestern, a regulated Montana utility, must purchase electricity under PURPA and related Montana law; PSC oversees PURPA implementation in Montana.
- In 1984, CELP's predecessor AEM and MPC entered a 35-year Power Purchase Agreement; the 1988 First Amendment fixed rates years 1–15 and introduced a formula for years 16–(end) using specific variables and PSC-approved methods.
- The rate formula uses annual adjustments based on Handy-Whitman Index and an annually determined incremental cost of capital (ICC).
- Dispute arose over contract years 16–17 (2004–2006) calculations when CELP claimed Northwestern used wrong variables, seeking roughly $22 million in damages across contract and tort claims; arbitration followed without Northwestern counterclaims.
- A three-arbitrator panel in San Francisco issued an Interim Award (Aug. 24, 2009) and a Final Award (Oct. 30, 2009) denying CELP damages while noting Northwestern breached the contract; it held each party should bear its own arbitration costs.
- District Court confirmed the Final Award (June 15, 2010). CELP then appealed, challenging vacatur/ modification of the award; the court and now the Montana Supreme Court focus on whether vacatur was abused.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Arbitrators’ adherence to contract variables | CELP argues the Panel used wrong variables and failed to apply contract-mandated inputs. | Northwestern contends the Panel reasonably interpreted the First Amendment and consistent inputs under the contract. | No abuse; panel within authority. |
| Panel's reliance on intent vs. contract language | CELP claims the Panel rewrote the contract based on intent of sophisticated parties rather than the written terms. | Northwestern asserts proper interpretation and adherence to contract terms and amendments. | No abuse; Panel acted within powers. |
| Equitable adjustments versus contract enforcement | CELP contends the Panel’s equity-based result deviates from contract enforcement. | Northwestern asserts no deviation; decision reflects contract framework. | No abuse; award respects contract. |
| District Court’s vacatur/modification standard | CELP asserts the award should be vacated or modified due to inconsistencies and legal errors. | Northwestern maintains no statutory basis to vacate or modify; award defensible. | District court did not abuse discretion; no grounds to vacate or modify. |
