Complete control chain in accordance with Section 14a EnWG: SMIGHT, Thüga SmartService and Robotron demonstrate solution in real operation

Karlsruhe/Munich/Dresden, 30 April 2026 - SMIGHT GmbH, Thüga SmartService GmbH and Robotron Datenbank-Software GmbH have jointly implemented the complete control chain in accordance with Section 14a EnWG in real operation. The solution maps the entire process in a standardised and market-compliant manner: from the measurement data-based congestion detection in the local network station to the acknowledged control action at the control box.

The implementation of §14a control takes place in an integrated architecture based on a division of labour:

• SMIGHT provides measured value-based congestion detection, dimensioning of the control commands and the MSB gateway
• As a service provider, Thüga SmartService handles the operational operation of CLS management, metering point operation, gateway administration and certificate management
• Robotron takes care of energy industry data processing, process logic and integration into market communication

This ensures that a bottleneck is not only recognised, but also systematically processed, correctly communicated, rectified and documented in an audit-proof manner.

Measurement data-based bottleneck detection as a starting point

Congestion detection begins at the local substation, where SMIGHT's measurement technology continuously records currents and voltages with output and phase accuracy. If a defined limit value is exceeded, the SMIGHT IQ Copilot automatically generates a bottleneck signal based on real grid conditions. This signal is automatically transferred to a standardised control process.

SMIGHT MSB Gateway as a bridge between the grid and the market

The SMIGHT MSB Gateway plays a central role in the architecture. It ensures secure and standard-compliant market communication within the smart meter PKI, encrypts the control commands and connects grid operation and metering point operation.

Complex requirements such as certificate management, key management and addressing via the directory service are integrated and implemented in an operationally manageable manner.

In combination with Robotron's backend systems, this ensures that control pulses are not only transmitted, but also correctly embedded and processed in the market processes.

Legally compliant: from bottleneck signal to market-side control

Thüga SmartService processes the bottleneck signal via Robotron's CLS management, so that the control chain is seamlessly implemented via the smart meter gateway to the control box in the field.

The implementation was carried out consistently in accordance with the regulatory requirements of the BSI and BDEW. Certificate-based market communication, secure key management and clearly defined roles and responsibilities ensure a technically robust and regulatory compliant solution.

Basis for the broad rollout

In the project, all process steps, from congestion detection, market communication and backend processing to operational control, were run through and validated in real operation. This provides a structured, standard-compliant architecture that can be transferred to other distribution network operators.
