It is generally deemed that increase in energy demand reflects
the higher economic status of the country. The inclusion of the
per capita natural gas consumption (Dmax=Capita) in logisticpopulation
approach will also be a function of the GDP at purchasing
power parity (PPP) per capita [27]. Additionally, the population
variable in logistic–population approach offers to generate different
scenarios of natural gas demand based on expected low-,
medium- and high-growth in population. At first, it was decided
to estimate Dmax=Capita based on Dmax obtained through implementation
of LMA. It was observed that although model adaptability was
in a good fit with historical natural gas consumption. But, forecasted
values of the natural gas demand under both approaches,
logistic and logistic-population were converging together in the
long-term due to their intrinsic saturating characteristics, resulting
in similar forecast. Therefore, in order to get diversity in results, we
decided to estimate the Dmax=Capita based on studies conducted in
the past.
