351 S.W.3d 588
Tex. App.2011Background
- Constellation filed a PUC complaint alleging ERCOT protocols were inconsistent and under-scheduling charges were improperly assessed.
- SOAH ALJ granted summary disposition for Constellation; Commission reversed, finding ERCOT settled charges correctly under the then-current protocols.
- Constellation sought district-court judicial review; court reversed, holding the RPRS under-scheduled protocol and procurement protocol irreconcilable.
- Appellants (Commission, Luminant, Joint Intervenors) argued for deference to Commission construction and no collateral attack.
- Constellation cross-appealed contending ERCOT could not charge more than its actual procurement costs; issue framed as revenue-neutral uplift in socialized costs.
- This appeal reviews whether the Commission correctly interpreted the protocols and upheld ERCOT’s under-scheduling charges against Constellation.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Does the Commission properly interpret the RPRS protocols? | Constellation argues the under-scheduled charge misreads the protocols. | Commission/Luminant argue the protocols harmonize and support the charges. | Yes; Commission interpretation is consistent with the text |
| Are the RPRS under-scheduled and procurement protocols in conflict? | Constellation claims irreconcilable conflict between 6.9.2.1.1 and 6.6.3.2.1. | Appellants contend the two protocols coexist harmoniously. | No conflict; harmonized interpretation proper |
| Should the district court have deferred to the Commission's construction? | Constellation argues the court misapplied deference to agency interpretation. | Appellants urge deference to Commission due to regulatory scheme. | District court erred in failing to defer |
| May ERCOT uplift under-scheduling costs to all QSEs while remaining revenue-neutral? | Constellation claims uplift cannot exceed actual costs. | Appellants assert uplift and revenue-neutral provision under 6.3.1(10) authorize socialization. | Yes; uplift is allowed and revenue-neutral |
| Is Constellation entitled to resettlement based on an uplift solution? | Constellation seeks uplift-based resettlement as correct method. | Appellants maintain the under-scheduled method is correct under the text. | No resettlement; Commission's order affirmed |
