Commonwealth Edison Company v. Illinois Commerce Commission
997 N.E.2d 762
Ill. App. Ct.2013Background
- Commonwealth Edison (ComEd) sought a $360 million delivery-rate increase in Docket No. 07-0566 based on a 2006 historical test year and pro forma additions through Q3 2008; the Illinois Commerce Commission (ICC) granted a smaller increase in the 2007 Rate Order and excluded Q3 2008 plant additions.
- This court, in a prior appeal, held the Commission used an erroneous methodology by excluding post-test-year accumulated depreciation and remanded to allow the Commission to revisit accumulated depreciation and ComEd’s request to include Q3 2008 additions.
- While the remand and subsequent litigation proceeded, ComEd continued to collect rates set in the 2007 Rate Order; this court’s opinion in the prior appeal issued September 30, 2010.
- The ICC later entered a Refund Order (Feb. 23, 2012) requiring ComEd to refund ~$36.7 million collected between Sept. 30, 2010 (date of the appellate decision) and May 31, 2011 (when new 2010 rates became effective), recalculating rate base to account for accumulated depreciation and excluding Q3 2008 additions.
- ComEd appealed the Refund Order, arguing (1) the ICC lacked jurisdiction to order refunds, (2) actual costs during the refund period eliminated any unjust enrichment so no refund was warranted, and (3) the Commission failed to comply with the remand regarding Q3 2008 plant additions.
Issues
| Issue | Plaintiff's Argument (ComEd) | Defendant's Argument (ICC/Respondents) | Held |
|---|---|---|---|
| Authority to order refund | ICC lacked jurisdiction; only a court’s equitable power can compel refunds | Independent Voters permits refunds on remand; Commission must implement appellate decision and may order refunds to prevent unjust enrichment | ICC had authority; Refund Order valid under Independent Voters and this court’s remand |
| Whether actual costs negate refund | Actual plant value and operating costs during refund period exceeded projected amounts, so no unjust enrichment or refund necessary | Refund computed as difference between rates actually charged and rates that would have been set consistent with the appellate opinion; actual costs not considered to avoid retroactive ratemaking | Held for ICC: must refund the difference; allowing actual-cost evidence would be improper retroactive ratemaking |
| Compliance with remand re: Q3 2008 plant additions | ICC failed to make new findings and should have allowed inclusion of Q3 2008 additions (estoppel/insufficient detail) | Commission implicitly found record lacked support for Q3 additions and cited Staff testimony; Commission as factfinder may exclude them | ICC complied with remand; substantial evidence supports exclusion of Q3 2008 additions |
| Methodology for refund calculation | ICC should have offset refund by revenues/costs from subsequent 2010 Rate Order or actual period costs | Refund must be difference between rates collected under the reversed order and rates that would have existed under the appellate court’s view; test-year rules prohibit mixing years | Held for ICC: refund formula follows Independent Voters; test-year principles bar retroactive adjustment based on later rates or hindsight costs |
