Ameren Union Electric Co.
We were part of a team representing AmerenUE in In the Matter of Union Electric Co., the largest electric utility in Missouri, in a major rate case. We dealt with a broad range of regulatory and constitutional issues, including the relationship between federal and state regulatory jurisdiction, the protection of contract rights, and the taking of unregulated property.
We were responsible for two of the highest “dollar value” issues in the case. For the more significant of the two, we defeated the unprecedented effort of the Public Service Commission’s staff to extend the Commission’s jurisdiction to include in the rate calculation for Missouri customers revenue from the utility’s out-of-state, unregulated affiliate, which sells power in the wholesale market. For the second, we achieved a reasonable return on equity for the utility.
