AGGM Austrian Gas Grid Management (AGGM) assumed on June 1st 2017 the role of market area manager (MAM) for the Eastern gas market area in Austria, which comprises all Austrian provinces except for Tyrol and Vorarlberg.

 Its responsibility in this role is to ensure that the individual gas suppliers are able to provide the required volumes of natural gas to all gas consumers everywhere in the country.
