LISINER Commissions 5 MW / 20 MWh Microgrid Energy Storage Project in the Czech Republic

As Europe’s power-market reforms continue and renewable generation expands, demand is growing for fast-response and longer-duration energy storage. Against this backdrop, LISINER has commissioned a 5 MW / 20 MWh microgrid energy storage project in the Czech Republic, providing more flexible and stable energy support for the local power system.

Located at 49.552943° N, 15.956876° E, the project is designed as a relatively independent and controllable microgrid, capable of switching flexibly between grid-connected and off-grid operation. When connected to the grid, it can support regional grid regulation; in off-grid mode, it can provide stable power to local loads, helping improve supply reliability and local energy self-sufficiency.

As the share of wind and solar continues to rise, fluctuations in renewable generation and changing load demand are placing greater pressure on grid flexibility. The microgrid can provide regulation support under these conditions, helping ease grid pressure while improving the flexibility and stability of local energy use.

The project uses LISINER’s TRITON containerized energy storage system. While the system supports a standard charge/discharge rate of ≤0.5P, the project operates at 0.25P, enabling a four-hour storage duration. The longer-duration configuration allows the system to provide sustained energy support over a wider time scale, better meeting the microgrid’s needs for continuous regulation and stable output.

The system supports charging at 0–60°C and discharging at −20–60°C, helping ensure reliable operation across varying environmental conditions.

The project is developed and owned by ENVI ENERGO a.s., with non-recourse debt financing provided by Česká spořitelna, part of Austria’s Erste Group. LISINER worked closely with local partners across construction and grid connection, building practical experience for further expansion in the European market.

LISINER will continue to deliver safe and reliable energy storage solutions to support the global energy transition.
