| In determining just and reasonable rates, tolls and charges, |
the commission shall fix a reasonable value upon all the property |
of a public utility and upon an electric plant to the extent paid |
for by the utility on the premises of any of its customers, which |
is used or required to be used in its service to the public |
within the State and a fair return on that property. In fixing a |
reasonable value, the commission shall give due consideration to |
evidence of the cost of the property when first devoted to public |
use and the prudent acquisition cost to the utility, less |
depreciation on each, and any other material and relevant factors |
or evidence, but the other factors shall may not include current |
value. In making a valuation, the commission may consult reports, |
records or other information available to it in the office of any |
state office or board. In the event of rate determinations for a |
public utility's ownership interest under a joint ownership |
agreement that are subject to the primary jurisdiction of the |
Federal Energy Regulatory Commission, the commission shall make |
the rate determinations in a manner that excludes from recovery |
in retail rates any cost found to be imprudent or excluded from |
wholesale rates by the Federal Energy Regulatory Commission. |
