VAC m = 1/12[KIn (1 - R)/(1 - R L) + On ]
Where, for a one year deferral:
VACm | = | utility's monthly value of avoided capacity, in dollars per kilowatt per month, for each month of year n; | |
K | = | present value of carrying charges for one dollar of investment over L years with carrying charges computed using average annual rate base and assumed to be paid at the middle of each year and present value to the middle of the first year; | |
R | = | (1 + ip)/(1 + r); | |
In | = | total direct and indirect cost, in mid-year dollars per kilowatt including AFUDC but excluding CWIP, of the avoided unit with an in-service date of year n, including all identifiable and quantifiable costs relating to the construction of the avoided unit that would have been paid had the avoided unit been constructed; | |
On | = | total fixed operation and maintenance expense for the year n, in mid-year dollars per kilowatt per year, of the avoided unit; | |
ip | = | annual escalation rate associated with the plant cost of the avoided unit(s); | |
io | = | annual escalation rate associated with the operation and maintenance expense of the avoided unit(s); | |
r | = | annual discount rate, defined as the utility's incremental after tax cost of capital; | |
L | = | expected life of the avoided unit; and | |
n | = | year for which the avoided unit is deferred starting with its original anticipated in-service date and ending with the termination of the contract for the purchase of firm energy and capacity. |
Am = [Ac (1 + ip)(m - 1) + Ao (1 + io) (m -1) ] /12 for m = 1 to t
Where: | Am | = | monthly early capacity payments to be made to the qualifying facility for each month of the contract year n, in dollars per kilowatt per month; | |
ip | = | annual escalation rate associated with the plant cost of the avoided unit; | ||
io | = | annual escalation note associated with the operation and maintenance expense of the avoided unit(s); | ||
m | = | year for which early capacity payments to a qualifying facility are made, starting in year one and ending in the year t; | ||
t | = | the term, in years, of the contract for the purchase of firm capacity; | ||
Ac = F[(1 - R)/(1 - Rt)] | ||||
Where: | F | = | the cumulative present value in the year that the contractual payments will begin, of the avoided capital cost component of capacity payments which would have been made had capacity payments commenced with the anticipated in-service date of the avoided unit(s); | |
R | = | (1 + ip)/(l + r); and | ||
r | = | annual discount rate, defined as the utility's incremental after tax cost of capital; and |
Ao = G[(1 - R) (1 - Rt)]
Where: | G | = | The cumulative present value in the year that the contractual payments will begin, of the avoided fixed operation and maintenance expense component of capacity payments which would have been made had capacity payments commenced with the anticipated in-service date of the avoided unit; and | |
R | = | (1 + io)/(l + r). |
PL = F/12{r/[1 - (1 + r)-t ]} + O
Where: | PL | = | the monthly levelized capacity payment, starting on or prior to the in-service date of the avoided unit; | |
F | = | the cumulative present value, in the year that the contractual payments will begin, of the avoided capital cost component of the capacity payments which would have been made had the capacity payments not been levelized; | ||
r | = | the annual discount rate, defined as the utility's incremental after tax cost of capital; and | ||
t | = | the term, in years, of the contract for the purchase of firm capacity. | ||
O | = | the monthly fixed operation and maintenance component of the capacity payments, calculated in accordance with paragraph (5)(a) for levelized capacity payments or with paragraph (5)(b) for early levelized capacity payments. |
