Sec. 436.17  Establishing energy or water cost data.

    (a) Each Federal agency shall establish energy costs in the base 
year by multiplying the total units of energy used in the base year by 
the price per unit of energy in the base year as determined in 
accordance with Sec. 436.14(c).
    (b) When energy costs begin to accrue in the base year, the present 
value of energy costs over the study period is the product of energy 
costs in the base year as established under Sec. 436.17(a), multiplied 
by the appropriate modified uniform present worth factor adjusted for 
energy price escalation for the applicable region, sector, fuel type, 
and study period consistent with Sec. 436.14, or as calculated by 
computer software provided or approved by DOE and used with the official 
discount rate and escalation rate assumptions under Sec. 436.14. When 
energy costs begin to accrue at a later time, subtract the present value 
of energy costs over the delay, calculated using the adjusted, modified 
uniform present worth factor for the period of delay, from the present 
value of energy costs over the study period or, if using computer 
software, indicate a delayed beneficial occupancy date.
    (c) Each Federal agency shall establish water costs in the base year 
by multiplying the total units of water used in the base year by the 
price per unit of water in the base year as determined in accordance 
with Sec. 436.14(c).
    (d) When water costs begin to accrue in the base year, the present 
value of water costs over the study period is the product of water costs 
in the base year as established under Sec. 436.17(a), or as calculated 
by computer software provided or approved by DOE and used with the 
official discount rate and assumptions under Sec. 436.14. When water 
costs begin to accrue at a later time, subtract the present value of 
water costs over the delay, calculated using the uniform present worth 
factor for the period of delay, from the present value of water costs 
over the study period or, if using computer software, indicate a delayed 
beneficial occupancy date.
