The Future of Market Communication: Secure, Flexible and Simple
We Accompany You during the Changeover to the AS4 Protocol
From October 1, 2023, the German energy market will take a further step towards the digitization of the energy supply industry. The AS4 protocol will then become the technical standard for digital market communication and ensure an increased security standard in data exchange. We support the transformation of the market partners and offer them the opportunity to react flexibly to the implementation.
For all market participants, the changeover represents a challenge that raises questions and creates uncertainty. We therefore attach particular importance to ensuring that the transformation proceeds consistently and as smoothly as possible and that the new market communication processes function as simply and automatically as possible.
