Market Communication in the Energy Industry

EDI@Energy compliant exchange of EDIFACT transmission data,
Schedule Data Exchange and Redispatch 2.0 process via email

Energy Market Communications EDI@energy

The Act on the Digitization of the Energy Transition required the highest IT security levels for critical infrastructures (KRITIS). Building on this, EDI@Energy regulations on the safe exchange of EDIFACT transmission files for market communication in the energy industry have been in force since 2017. The latest regulatory additions include the introduction of both Schedule Data Exchange and the Redispatch 2.0 process. Version 1.5, valid from 01.04.2022, specifies, among other things, a minimum of 3072 BIT certificate key length as a secure data exchange requirement for market participants. However, The following remains unchanged: “If no agreement on a transmission channel is possible, email must be offered in any case“. Certificate management according to the applicable requirements is a major challenge.

Automated implementation of new communication requirements in the Energy Industry

The constant adaptation of specifications implies ongoing adjustments in the implementation phase. We support you by further developing the Z1 SecureMail Gateway Energy Module on schedule.

We offer more than the latest EDI-compliant algorithms for every regulatory update!

german edi energy email encryption and signing gateway

Our Easy. Secure. Encrypted. electronic communications claim is not fulfilled by only providing appropriate algorithms such as RSASSA-PSS for EDI-compliant emails. We go the extra mile, so you don’t have to. Previously, we have already implemented updated EDI@Energy regulations that require little to no effort for operators. All while ensuring automatic exchange of algorithms and keeping existing configurations intact. Zertificon’s Energy Module made it possible to implement the mandatory requirements on the specified deadlines with minimal effort during all update phases. Additionally, individual internal processes can be set up, enabling different configurations depending on the communication partner.

Regulatory adjustments to the safe exchange of EDIFACT transmission files will continue. And following the data exchange schedule and Redispatch 2.0 processes, we expect further EVU regulations to follow EDI@Energy best practices. Email remains the lowest common denominator in communication and will continue to be valid as a fallback solution. As such, you are always very well placed for secure communication in the energy industry with Zertificon. In addition to RSASSA-PSS or new key lengths, we always pay special attention to the usability and efficiency of your workflows. You can invest in a secure and carefree future in market communication with Zertificon.

Clearing Cases

If the communication partner is not compliant …

With the Energy Module as an extension to the Z1 SecureMail Gateway, you can exchange data conveniently, automatically, and immediately at the appropriate validity time in compliance with the guidelines. If the other party is not compliant, i.e., does not adhere to the latest algorithm for encryption and signature, the communication does not have to be interrupted. By forwarding the message to a clearing case mailbox, it can be processed in a structured manner. You will be informed via alerts if clearing cases accumulate over a short period. This way, you do not lose valuable time resolving special incidents.

Alternatively, policies for dedicated market partner addresses can be configured to allow less stringent compliance enforcement. Fluent communication is thus ensured even in the event of minor non-compliance with the policy.

Energy companies trust Zertificon for secure email communications

Zertificon has always been the competent partner for all complex challenges in secure digital communication for energy companies. As early as 2004, energy providers were among the first customers to use Z1 SecureMail Gateway for encrypted email exchange and digital signatures according to the German Federal Network Agency requirements. Our Energy Module has satisfied our existing customers and won over many other energy companies, Metering Point Operators (MOPs), Distribution Network Operators(DNOs), and Transmission System Operators (TSOs) as new customers.

Why it pays to switch to Zertificon

Notably, new customers who switch to us from other solutions report their surprise at how Z1 SecureMail Gateway simply does its job in the background. Once set up, it just runs. Feedback showed: 80% less effort!
