Fla. Stat. § 366.057

A public utility shall provide notice to the commission at least 90 days before the full retirement of an electrical power plant if the date of such retirement does not coincide with the retirement date in the public utility’s most recently approved depreciation study. No later than 90 days after such notice, the commission may schedule a hearing to determine whether retirement of the plant is prudent and consistent with the state’s energy policy goals in s. 377.601(2). At a hearing scheduled under this section, the utility shall present its proposed retirement date for the plant, remaining depreciation expense on the plant, any other costs to be recovered in relation to the plant, and any planned replacement capacity.
