The German Federal Network Agency (BNetzA) has decided to implement a new communication standard for market communication in the gas sector by 1 April 2025 (BK7-19-001, GeLi Gas 2.0). 

The switchover from standard e-mail via SMTP and AS2 to the AS4 secure transmission channel (Applicability Statement 4) is obligatory with this new ruling. Communication must be secured through use of the Smart Metering PKI (public key infrastructure) of the German Federal Office for Information Security (BSI), while also complying with defined cryptographic specifications.
