AS4 market communication gas

Compliant communication for energy suppliers – gas and schedule data gas with Z1 Energy

Since April 1, 2025, the changeover to AS4 for market communication gas introduced by the German Federal Network Agency (BNetzA) has been mandatory for all market participants. This also includes the schedule process gas, which is defined by Trading Hub Europe (THE). Z1 Energy is an all-in-one communication solution for the energy sector. We implement all requirements on time and in compliance with the official regulations – allowing you to focus fully on your core business.

Missed the deadline? Switch to AS4 now with little effort – with our Z1 Energy solution.

Key features of Z1 Energy for market communication and schedule process gas

AS4 certificate triples

Automated handling of AS4 certificates for gas and schedule gas

Z1 Energy customers obtain AS4 certificate triples (EMT.MAK) directly via Zertificon. We offer certificates from the registered Sub-CA DARZ.CA. In addition to procurement, Z1 Energy also manages, searches and stores your own and external AS4 certificates.

Crypographic Module

The HSM requirement doesn’t apply to all market roles: Companies that are passive external market participants can meet the required Security Level 1 using our significantly more cost-effective Z1 Cryptographic Module.

Z1 Energy offers a simple and largely automated market partner management that combines all relevant functions and market processes in one central system. Market partners are identified using DVGW code numbers.

Z1 Energy can be seamlessly integrated into your ERP or B2B applications – either via REST API or email interface.

By the end of 2025, our Z1 Energy ERP Adapter for SAP MaCo Cloud will be available as an additional integration option.
