(ANSA-AFP) - BELGRADE, DEC 4 - Enaon (Italgas Group) is offering 1 billion in investments for Greece's energy transition by 2031, according to a business plan presented today in Athens. The plan calls for the digitalisation of Greece's gas network, including distribution to underserved areas. There are also plans to develop and integrate renewable gases such as biomethane. In total, there will be 2,500 km of new networks, over 2,200 of which will be low-pressure and the remainder medium-pressure, primarily for the supply of gas to industrial clients. (ANSA-AFP).
