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?

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

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.

Z1 Cryptographic Module – an affordable HSM alternative

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.

Efficient market partner management of your gas market partners

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.

Smooth integration with your gas business application

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 SAP MACO will be available as an additional integration option.

Clear monitoring for gas / schedule gas communication

An intuitive monitoring with integrated reporting ensures full transparency and provides detailed data for effective error analysis.
