Based on the available information, certain data analysis is made taking into account both the market shares of the enterprises in the sector and the number of active competitors, turnover or output, while the economic approach was tailored to availability of the data for each market. The Natural Gas Sector has been analyzed in terms of market concentration, with the help of the Herfindahl-Hirschman and Concentration Ratio indicators.
