What is market communication in the energy industry?

Market communication (MaKo) refers to the exchange of information between participants in the German energy market. To facilitate this communication, standardized data formats have been introduced to ensure automated and efficient communication between energy suppliers. This standardization process was driven by the German Federal Network Agency (BNetzA), the German Association of Energy and Water Industries (BDEW) and the German Technical and Scientific Association for Gas and Water (DVGW), resulting in the standardization of business processes and data formats.

Particular mention should be made of the EDI@Energy expert group, which, under the leadership of BDEW, has been instrumental in developing regulations for the secure exchange of transmission files.

What is AS4?

AS4 is a communication protocol and stands for Applicability Statement 4. AS4 was developed specifically for use in B2B communication and is intended to ensure the security, reliability and interoperability of electronic messages. It is based on the Electronic Data Interchange (EDI) standards.

EDI, short for Electronic Data Interchange, facilitates the exchange of structured business documents using a standardized electronic format such as EDIFACT (Electronic Data Interchange for Administration, Commerce and Transport). These EDIFACT files play a crucial role in the business processes for supplying customers with electricity in accordance with the provisions of GPKE (Gemeinsame Prozesskoordination Elektrizität). In addition, AS4 provides a standardized method for exchanging business documents and messages between different parties via the Internet.

Since when is AS4 mandatory?

The German Federal Network Agency (BNetzA) published the specification for the future safeguarding of electronic market communication for electricity on March 31, 2022:

Why AS4 with NoSpamProxy? The advantages at a glance.

  • Conversion of the emails into AS4 messages

    NoSpamProxy customers have the possibility to send EDIFACT files via email. NoSpamProxy takes over the conversion of these emails into AS4 messages and forwards them to the web service of the communication partner.

  • Conversion to emails with EDIFACT files

    External communication partners can send AS4 messages to a NoSpamProxy endpoint. NoSpamProxy transforms these messages into emails containing the relevant EDIFACT files.

  • AS4 communication in the Fahrplan process

    The Bundesnetzagentur requires smooth communication between all market partners in the Fahrplan process via AS4 from December 1, 2024, with parallel operation starting on October 1, 2024. NoSpamProxy offers a secure exchange of Fahrplan data via AS4.

  • Everything available instantly - for easy operation

    After logging in to a registration page, NoSpamProxy customers have the data exchange addresses of their market partners, the URL for calling the AS4 web service (AS4 address), and the certificate with the public key immediately available. This is critical because market partners need to exchange the data exchange addresses and the certificates to be used before the first data exchange to ensure extensive automation. NoSpamProxy simplifies this step and makes it extremely user-friendly.

  • Dedicated user interface for AS4

    NoSpamProxy customers additionally benefit from a dedicated user interface. Market communication administrators can conveniently manage market partners, required certificates and AS4 endpoints via this interface. A dedicated user group for these administrators as well as standalone message tracking enable smooth market communication without the need to involve email administrators.

  • Automatic integration of all BDEW market partners

    All relevant data of our customers’ communication partners are automatically imported into the NoSpamProxy configuration. Manual import is not required.

  • Gas market communication via the AS4 protocol

    From April 1, 2025, all gas suppliers must communicate via the AS4 protocol. The transition period of six months begins on 1 October 2024. NoSpamProxy offers secure data exchange for all market partners.

  • Book the AS4 module easily

„The self-learning whitelisting and the intensive use of sender reputation techniques such as DANE, DKIM, DMARC and SPF were decisive factors in our decision to use NoSpamProxy. We are not aware of any other product that combines these functions so effectively and can therefore reduce the administrative workload and the number of helpdesk tickets to such an extent.“
