Sec. 436.21  Savings-to-investment ratio.

    The savings-to-investment ratio is the ratio of the present value 
savings to the present value costs of an energy or water conservation 
measure. The numerator of the ratio is the present value of net savings 
in energy or water and non-fuel or non-water operation and maintenance 
costs attributable to the proposed energy or water conservation measure. 
The denominator of the ratio is the present value of the net increase in 
investment and replacement costs less salvage value attributable to the 
proposed energy or water conservation measure.
