Construction of a 100 MWh, 50 MW Modular Energy Storage Facility — Site Update

11/07/2025

Construction of a modular UZE with a capacity of 100 MWh and a power of 50 MW!

We will tell you what is happening on the site.

The foundation work and engineering preparation stage is currently being completed.

Current status of implementation:

Foundation work

✔️ Concreting of the UZE transformer substation foundations has been completed, and a limestone base for the 110 kV switchgear has been laid (70% complete).

✔️ Three layers of waterproofing have been applied to the foundations in accordance with technical requirements.

MPm-1 oil receiver

✔️ Concrete preparation and concreting of the bottom slab completed.

✔️ Installation of the reinforcement cage and walls of the structure is in progress.

Engineering networks

✔️ A storm sewer system and additional drainage made of D-150 mm PVC pipes with a length of 36 m have been laid.

✔️ Trenches for 35 kV cable lines have been prepared.

Next stages:

🔸 Installation of FM foundations for 110 kV main equipment (10 units) is underway.

🔸 Installation of the 110 kV switchgear grounding circuit and preparation for the installation of transformer equipment.

The 100 MWh capacity and 50 MW power UZE will become an important element of the energy infrastructure.
