THE FULL TEXT OF THE PROPOSED RULE IS:
25-6.044 Continuity of Service.
(1) Definitions applicable to this part: (a) “Area of Service.” A geographic area where a utility provides retail electric service. An Area of Service can be the entire system, a district, or a subregion of the utility’s system in which centralized distribution service functions are carried out a region into which a utility divides its system.
(b) through (p) No change.
(q) Planned Service Interruption.” A Service Interruption initiated by the utility to perform necessary scheduled activities, such as maintenance, infrastructure improvements, and new construction due to customer growth. Customers are typically notified in advance of these events.
(2) Each utility shall keep a record of its system reliability and continuity of service data, customers’ Service Interruption notifications, and other data necessary for the annual reports filed under these rules. These records and data shall be retained for a minimum of ten years from the filing of each annual report. The utility shall record each Outage Event as planned or unplanned and shall identify the point of origination such as generation facility, transmission line, transmission substation equipment, or distribution equipment. The cause of each Outage Event shall be determined and recorded in a standardized manner throughout the utility. The date and time of the Outage Event and the number of Service Interruptions for the Outage Event shall also be recorded.
(3) through (5) No change.

25-6.0455 Annual Distribution Service Reliability Report.
(1) Each utility shall file a Distribution Service Reliability Report with the Director of the Commission’s Division of Economic Regulation on or before March 1st of each year, for the preceding calendar year. The report shall contain the following information:
(a) The utility’s total number of Outage Events (N), categorized by cause for the highest 10 causes of Outage Events, the Average Duration of Outage Events (L-Bar), and Average Service Restoration Time (CAIDI). The utility shall record these data and analyses on Form PSC/ECR 102-1, entitled “Outage Events” which may be obtained from the Division of Economic Regulation, 2540 Shumard Oak Boulevard, Tallahassee, Florida 32399-0850, (850) 413-6900;
(b) Identification of the three percent of the utility’s Primary Circuits (feeders) with the highest number of feeder breaker interruptions. For each primary circuit so identified the utility shall report the primary circuit identification number or name, substation origin, general location, number of affected customers by service class served, Number of Outage Events (N), Average Duration of Outage Events (L-Bar), Average Service Restoration Time (CAIDI), whether the same circuit is being reported for the second consecutive year, the number of years the primary circuit was reported on the “Three Percent Feeder List” in the past five years, and the corrective action date of completion. The utility shall record these data and analyses on Form
(c) The reliability indices SAIDI, CAIDI, SAIFI, MAIFIe, and CEMI5 for its system and for each district or region into which its system may be divided. The utility shall report these data and analyses on Form PSC/ECR 102-3, entitled “System Reliability Indices” which may be obtained from the Division of Economic Regulation,
(d) The calculations for each of the required indices and measures of distribution reliability;
(2) The Distribution Service Reliability Report will exclude the impact of all service interruptions associated with generation and transmission disturbances governed by Section 25-6.018(2) and (3), Florida Administrative Code. A utility may exclude from the Annual Distribution Service Reliability Report the Outage Events directly caused by one or more of the following: planned interruptions, a storm named by the National Hurricane Center, a tornado recorded by the National Weather Service, ice on lines, a planned load management event, an electric generation disturbance, an electric transmission system disturbance, or an extreme weather or fire event causing activation of the county emergency operation center.
(3) The report shall contain the following information on an actual and adjusted basis: A utility may submit a request to exclude an Outage Event from the Annual Distribution Service Reliability Report that is not specifically provided for in subsection 25-6.0455(2), F.A.C. Such a request must be filed with the Commission’s Division of the Commission Clerk and Administrative Services within 30 days of the Outage Event for which an exclusion is being requested. The Commission will approve the request if the utility is able to demonstrate that the outage was not within the utility’s control, and that the utility could not reasonably have prevented the outage.
(a) The utility’s total number of Outage Events(N), categorized by cause for the highest ten causes of Outage Events, the Average Duration of Outage Events (L-Bar), and Average Service Restoration Time (CAIDI). The utility shall record these data and analyses on Form
(b) Identification of the three percent of the utility's Primary Circuits (feeders) with the highest number of feeder breaker interruptions. For each primary circuit so identified the utility shall report the primary circuit identification number or name, substation origin, general location, number of affected customers by service class served, Number of Outage Events (N), Average Duration of Outage Events (L-Bar), Average Service Restoration Time (CAIDI), whether the same circuit is being reported for the second consecutive year, the number of years the primary circuit was reported on the “Three Percent Feeder List” in the past five years, and the corrective action date of completion. The utility shall record these data and analyses on Form
(c) The reliability indices SAIDI, CAIDI, SAIFI, MAIFIe, and CEMI5 for its system and for each district or region into which its system may be divided. The utility shall report these data and analyses on Form
(d) The calculations for each of the required indices and measures of distribution reliability.
(4) Adjusted distribution reliability data may omit Outage Events directly caused by:
(a) Planned Service Interruptions;
(b) A storm named by the
(c) A tornado recorded by the National Weather Service;
(d) Ice on lines;
(e) A planned load management event;
(f) Any electric generation or transmission event not governed by Section 25-6.018(2) and (3),
