of the sum of (i) the non-gas fixed costs allocated to BESS service

in the design of Natural's underlying base storage rates and (ii)

all variable costs reflected in BESS rates. The determination of

any such revenue credit shall be made on an annual basis,

commencing with the period ending November 30, 1994 and annually
