What changed
FERC has formally instituted a Section 206 proceeding under the Federal Power Act against Tucson Electric Power Company et al. (Docket EL26-55), accompanied by establishment of a refund effective date. This is a significant enforcement mechanism that places the burden on the utility to demonstrate its rates remain just and reasonable. The proceeding scope encompasses the utility's rate agreement and any associated charges to customers.
Tucson Electric Power and affiliated entities named in the proceeding must actively participate in the FERC process, potentially facing rate modifications and customer refunds retroactive to the established refund effective date. The utility should prepare comprehensive justification documentation for its existing rate structure, cost of service methodology, and revenue requirement calculations. Failure to adequately defend rate levels could result in ordered refunds with interest to customers.
What to do next
- Prepare and submit rate justification documentation to FERC demonstrating current rates are just and reasonable
- Designate representatives and coordinate legal/compliance responses for the Section 206 proceeding
- Review historical rate filings and cost of service data to assess potential refund exposure
Penalties
Potential customer refunds with interest retroactive to the refund effective date if rates are found not to be just and reasonable
