Partnerships

Three partnerships are on record, tiered flagship and core.

• Theben Smart Energy (advalju joint venture)flagshipStrategic or Co-development Partner · 1 January 2023In 2023, Lackmann founded advalju as a joint venture with Theben Smart Energy to focus on CLS-Management and value-added services. advalju developed the aEMT platform for §14a EnWG and §9 EEG compliance. The platform operates as either a standalone solution integrated with a customer's existing MSB infrastructure or as a fully integrated service within Lackmann's MSB platform. The joint venture combines Lackmann's metering operations expertise with Theben's hardware capabilities (CONEXA 3.0 SMGW, Selexa control boxes, value-added modules). This is Lackmann's most strategically important partnership, targeting the mandatory CLS-Management rollout required by end of 2025.
• IskraemecocoreTechnology or IntegrationIskraemeco is a long-standing strategic technology partner for Lackmann in the metering hardware domain. Lackmann highlights Iskraemeco's sustainability practices as a benchmark and a model for its own operations. The partnership dates back decades, with Iskraemeco supplying electricity meters (MT-series products) and Lackmann distributing these through its nationwide sales and installation network. In 2014, Iskraemeco awarded Lackmann the Golden Meter for selling 10 million Iskra meters in Germany.
• Theben (Hardware Supplier)coreTechnology or IntegrationTheben supplies key smart metering hardware to Lackmann including the CONEXA 3.0 Smart Meter Gateway (BSI-certified), Selexa R and Selexa D FNN control boxes, and value-added modules. These products are integrated into Lackmann's aEMT/CLS-Management solution and distributed through Lackmann's sales and installation network.
