(1)
				PREVENTATIVE MAINTENANCE PLAN. Each utility or other person subject to this
				chapter, including persons who own electric generating facilities in this state
				who provide service to utilities with contracts of 5 years or more, shall
				develop and have in place its own preventative maintenance plan. This section
				is applicable to electric generating facilities as set forth at s.
				196.491(5)
				(a)1, Stats. Each plan shall include, among
				other things, appropriate inspection, maintenance and replacement cycles where
				applicable for overhead and underground distribution plant, transmission,
				generation and substation facilities.
(2) CONTENTS OF THE PLAN.
(a)
Performance standard
.
				The preventative maintenance plan shall be designed to ensure high quality,
				safe and reliable service, considering: cost, geography, weather, applicable
				codes, national electric industry practices, sound engineering judgment and
				experience.
(b)
Elements of
				the plan
.
1. Inspection.
a. The plan under sub. (1) shall include a
				schedule for the periodic inspection of all facilities owned and operated by
				the utility and used to provide electric service to its customers. The plan
				under sub. (1) shall describe the method for inspection of each type of
				equipment as designated by the reporting utility. Checklist/report forms shall
				be included in the plan under sub. (1).
b. The plan under sub. (1) shall include
				guidelines for inspectors to determine the condition of a facility or piece of
				equipment.
2. Condition
				rating criteria. A rating criteria shall be established to grade the condition
				of a facility or piece of equipment. Rating criteria for generating facilities
				should conform to generator availability data system (GADS) requirements as
				reported to the national electric reliability council, or other accepted
				industry practices.
3. Corrective
				action schedule. The results of inspections, assessments and condition rating
				criteria shall be used to define the schedule for implementing maintenance on
				the facility or piece of equipment. The plan under sub. (1) shall describe how
				facilities or equipment corrective action schedules are added to the utility's
				budget.
4. Record keeping. Each
				utility shall maintain records to allow auditing of its preventative
				maintenance plan implementation. The records shall include inspection dates,
				condition rating, schedule for repair (if applicable) and the date of
				completion of the repair. Inspection and repair records shall be retained for a
				minimum of ten years.
5. Filing of
				plans. Each utility, as well as the transmission company created by s.
				196.485,
				Stats., shall file a plan in compliance with this rule within 180 days of
				acceptance of the rules or, in the alternative, within 180 days after the
				utility transmission company or other person subject to this chapter begins
				operation of a facility subject to this chapter.
6. Reporting requirements. Each utility shall
				provide a periodic report to the commission showing compliance with its
				preventative maintenance plan. The report shall include a list of inspected
				circuits and facilities, the condition of facilities according to established
				rating criteria, schedules established and success at meeting the established
				schedules. For generation facilities, the report shall include a summary of
				each generating unit's operating performance statistics based on the utility's
				GADS data, or other accepted industry data convention. Reported generating unit
				performance data shall include net dependable capacity, capacity factor, forced
				outage rate, scheduled outage factor, primary fuel and production technology
				type. The commission shall establish a periodic report schedule for each
				utility of at least once every 2 years.
7. Exchange of information. At least
				annually, utilities shall exchange planned outage information for the coming
				year for expected maintenance and other outages of generators of 50 MW or more
				and transmissions lines of 100 kV and higher voltage. Utilities shall also
				supply the same information for nonutility generators of 50 MW or more in their
				control areas. Utilities shall exchange updates of such information as soon as
				reasonably practicable when such updated information becomes known.
