AK REGTP (Arbeitskreis Regulierung Elektrizität Gas Telekommunikation Post) is a working group dealing with all matters regarding the German regulation authority "Bundesnetzagentur" (former "REGTP") for electricity, gas, telecommunications and post. It is a platform for communication between its members and towards the regulation authorities as well as the legislator.

AK REGTP supports its members in the establishment and maintenance of their regulation management. An internal regulation management has become essential for energy companies after the amendment of the German energy act in 2005.
