The commission, in its discretion, may include in the valuation a reasonable allowance for construction work in progress but, in no event, may such an allowance be made by the commission until it has determined that the particular construction project is at least seventy-five per cent complete.
In determining the percentage completion of a particular construction project, the commission shall consider, among other relevant criteria, the per cent of time elapsed in construction; the per cent of construction funds, excluding allowance for funds used during construction, expended, or obligated to such construction funds budgeted where all such funds are adjusted to reflect current purchasing power; and any physical inspection performed by or on behalf of any party, including the commission's staff.
A reasonable allowance for construction work in progress shall not exceed ten per cent of the total valuation as stated in this division, not including such allowance for construction work in progress.
Where the commission permits an allowance for construction work in progress, the dollar value of the project or portion thereof included in the valuation as construction work in progress shall not be included in the valuation as plant in service until such time as the total revenue effect of the construction work in progress allowance is offset by the total revenue effect of the plant in service exclusion. Carrying charges calculated in a manner similar to allowance for funds used during construction shall accrue on that portion of the project in service but not reflected in rates as plant in service, and such accrued carrying charges shall be included in the valuation of the property at the conclusion of the offset period for purposes of division (C)(9) of section 4909.05 of the Revised Code.
From and after April 10, 1985, no allowance for construction work in progress as it relates to a particular construction project shall be reflected in rates for a period exceeding forty-eight consecutive months commencing on the date the initial rates reflecting such allowance become effective, except as otherwise provided in this division.
The applicable maximum period in rates for an allowance for construction work in progress as it relates to a particular construction project shall be tolled if, and to the extent, a delay in the in-service date of the project is caused by the action or inaction of any federal, state, county, or municipal agency having jurisdiction, where such action or inaction relates to a change in a rule, standard, or approval of such agency, and where such action or inaction is not the result of the failure of the utility to reasonably endeavor to comply with any rule, standard, or approval prior to such change.
In the event that such period expires before the project goes into service, the commission shall exclude, from the date of expiration, the allowance for the project as construction work in progress from rates, except that the commission may extend the expiration date up to twelve months for good cause shown.
In the event that a utility has permanently canceled, abandoned, or terminated construction of a project for which it was previously permitted a construction work in progress allowance, the commission immediately shall exclude the allowance for the project from the valuation.
In the event that a construction work in progress project previously included in the valuation is removed from the valuation pursuant to this division, any revenues collected by the utility from its customers after April 10, 1985, that resulted from such prior inclusion shall be offset against future revenues over the same period of time as the project was included in the valuation as construction work in progress. The total revenue effect of such offset shall not exceed the total revenues previously collected.
In no event shall the total revenue effect of any offset or offsets provided under division (A)(1) of this section exceed the total revenue effect of any construction work in progress allowance.
