Practical Results of Forecasting for the Natural Gas Market

Autor: Edvard Govekar, Primoz Potocnik

Publikováno v: Natural Gas

Natural gas consumption forecasting is required to balance the supply and consumption of natural gas. Companies and natural gas distributors are motivated to forecast their consumption by the economic incentive model that dictates the cash flow rules
