31 electricity needs in Libya should not be less than consumption. If that happens, it
will shake up the Libyan economy. Besides that, attention should be paid to that the electric power will be lost, as long as we have not resolved the bias in
producing electricity, should pay attention to power consumption and loss of electricity, or in other words to meet the demands for electricity in producing
electricity it needs to accumulate between electricity consumption and electricity loss.
4.3.6 Production cost in the process of distributing electricity to Libya
Production costs for producing electricity to be distributed to consumers as in the Table 4.11.

4.3.8 The Mathematical Model is Based On Forecasting
Formula of forecasting: Q = a + b × a × y 4.1
Where, a
= amount at the initial year b
= coefficient y
= difference between forecasting year target and the initial year Example: - mathematical forecasting of POP for 2017
y = 2017-2000 = 17 The increase in the amount of fuel consumption 2000-2010
Ratio of population = 2010-2000
= 6,355,112-5,231,189 =1123923
= 112392310 = 112392.3
