ees Europe 2023 Expo in Munich – Leclanché LeBlock Energy Storage System Optimises Renewable Energy Storage

Mon Jun 12


  • LeBlock is a plug and play modular energy storage system for microgrids, solar plants and renewable energy plant operators
  • The advanced system is designed with enhanced safety features and reduces time and costs for transport, installation, relocation, expansion and recycling of energy storage solutions


YVERDON-LES-BAINS, Switzerland, 12 June 2023 – At ees Europe 2023 in Munich, Leclanché SA (SIX: LECN), one of the world’s leading energy storage solution providers, will present its innovative modular energy storage system, LeBlock™, at booth C3.390 from the 14th to 16th of June.

Recently, Leclanché installed its first operational multi-MWh LeBlock system for a Greek transmission systems operator (TSO), to maximise the energy consumption of its photovoltaic systems. At the exhibition’s inaugural edition in 2021, the plug and play system was among the finalists for the ees Award.

 Enhanced safety

In addition to its fire-resistant construction and fire detection and suppression system, LeBlock features an emergency stop to activate a controlled shutdown, either manually or automatically, when Leclanché Energy Management System (LEMS) detects anomalies. Each Battery Block is equipped with a standard deflagration panel to release internal overpressure in a safe manner, designed per NFPA 68.

Reduced total cost of ownership

LeBlock is the ideal solution for use in microgrids and a wide range of utility applications. Utilities can rapidly and efficiently maximise the use of their renewable solar and wind assets and provide them on demand using the highly secure, fully modular and scalable system. LeBlock is easily installed on site and its energy capacity can also be increased by simply adding more LeBlock units. Overall, the combination of plug-and-play connections, simplified logistics, minimal planning effort and rapid installation results in time and cost savings of up to 40 percent, as well as lower total cost of ownership.

Simplified logistics, installation and safe operation

Leclanché’s LeBlock energy storage system consists of five-foot-wide fully pre-installed and configured BatteryBlock and CombiBlock units that are easily combined through plug-and-play connections – including high voltage interconnects, communication and thermal management systems. Four LeBlock units attached together form the equivalent of a 20-foot container. These pre-assembled, CSC-certified LeBlock units allow for easy transport by land or sea directly to the installation site. Moreover, no site-specific cabling is required for on-site installation and no additional transport containers are needed eliminating packaging waste.

“Crucially, LeBlock enhances safety and reduces both the total cost of ownership and its carbon footprint. That is what makes our innovative design so successful, but we don’t just want to stop there. At ees Munich, we will be giving detailed insight on our newly developed LeBlock 2.0, which we plan to launch by the end of the year,” says Guido Guidi, SVP Global Sales, Leclanché Stationary Storage. “We look forward to many good conversations at the fair.”
