AVAILABILITY BASED TARIFF
ABT or availabilty based tariff is a tehnical term associated with the transmission of power. It was with the introduction of this plan several disputes were finalised . A stability and responsibility was made in the grid through this plan.This abt is effective in the generating side. There are mainly two costs which is in generation.They are fixed costs and variable costs.
FIXED COSTS
Fixed cost is determined mainly by the day by day or annual generation of the station. These fixed charges are in availability tariff. If the total production done is less than what was expected then the station will be getting a lesser payement. And if the generation is greater than the expected one then company will get the higher payments.This is termed as "capacity charge".
VARIABLE COSTS
Variable cost is that dependent on the fuel costs ,daily running costs etc. In availability tariff the reimbursement is given through variable costs. This charge is termed as "energy charge".If the production is above the scheduled production , then the rate will be varing dependent on the grids frequency. If the scheduled production is of 500 MW and the plant is producing 550MW , then the rate will depend on the current electrical system. If frequency is less than 50.0 then plant gets more .If frequency is greater than 50.0 hz, then plant will be only getting what was actually being scheduled. No extra charges will be given to plant.
The main components of ABT are
Capacity charge
linked to plants capacity of generation and towards fixed costs.
Energy charge
linked to the fuel costs of production and towards variable costs.
Deviation payment
linked to system conditions and can be negative (in case the generation is less than what was scheduled)
