AVAILABILITY BASED TARIFF
(A) CAPACITY CHARGE
(B) ENERGY CHARGE
(C) ADJUSTMENT FOR DEVIATIONS (U I CHARGE)
Where
(A) = a function of the Ex-Bus MW availability of Power Plant for the day declared before the day starts x SEB’s % share
(B) = MWh for the day as per Ex-Bus drawal schedule for the SEB finalised before the day starts x Energy charge rate
(C) = Σ (Actual energy interchange in a 15 minute time block – scheduled energy interchange for the time block) x UI rate for the time block
TOTAL PAYMENT FOR THE DAY = (A) + (B) ± (C)
