Tucson Electric Power says it plans to refund customers $9.5 million dollars in over-collected fees.

According to a decision filed by TEP with the Arizona Corporation Commission, the refund period could span 1-month, 2-months, or even 12-months.

Under this proposal, TEP would apply credits to residential customers based on usage, measured by kilowatt-hours. Non-residential customers would receive their refund based on a percentage of the bill.
