Energy: April 1986), p. 99.

J Average general obligation, mixed quality State and local bond yield as
of May 7, 1987, from Federal Reserve Statistical Release, May 11, 1981.
J Assumes a 30-year straight-line depreciation (present value).
?J Insurance costs based on FERC Generalized Power Value (PGPV) as reported
in Western Area Power Administration, Power Value Determinations
(Department of Energy: April 1986), p. A-11.
J Assumes that public entities pay no State or local income or ad valorem
taxes.
J Annual fixed fuel costs based upon following calculations:
Fuel Stockpile (75 days) x 24 hours x Plant Heat Rate
(11,377 KWh/BTU) x Plant Factor (489x) x Fuel Cost (115.2 cents per
BTU) x Annual Carrying Cost of Money (6.57X) x Unit Correction Factor
(-10 x 100,000,000,000,000)
J Operation and Maintenance (0&M) and Administrative and General (A&G)
expenses based on FGPV and adjusted for inflation using Producer Price
Index (1984-85). For FGPV see Western, Power Value Determinations, p.
A-9.
J Based on FGPV as reported in Western, Power Value Determinations,
pp. A-13 and A-13a. Investment and 0&M and A&G costs adjusted for
inflation.and cost of money assumed to be 6.57%.
The Mechanical Availability Adjustment reflects the superior mechanical
reliability and availability of the hydrogenerator. It is equivalent to
the ration of the availability of the hydrogenerator as a percentage of a
given period to the availability of the thermal facility as a percentage
of the same period.
DJ The hydrological flexibility adjustment reflects the superior flexibility
of the hydrogenerator to respond to regular fluctuations in load and to
provide ready spinning reserves. The adjustment is equal td 5%. This
figure represents a standard adjustment. See Western, Power Value
Determinations, p. III-20.
12 1985 average annual cost of coal for steam plants of 50 MW or greater
size in Mountain Census Division from, Energy Information Administration,
Cost and Quality of Fuels for Electric Utility Plants, 1985 (Department
of Energy: July 1986), Table 40, p. 52.

LJ Provided by the Upper Colorado Region of the Bureau of Reclamation.
Figures provided in Western, Power Value Determinations, page A-10.
Adjusted for inflation in 1984-85 using PPI.
Based on formula provided in Ibid., p. A-10.
Assume loss of 50 MW of Flaming Gorge Capacity would occur in August and
September, thus making it unavailable for marketing during the entire
summer season.
