A project in development in partnership with CET-Nord: a 70 MW / 140 MWh battery storage system and 25 MW of gas-engine cogeneration, with commissioning planned for 2028.
The project brings together, on the CET-Nord site, a battery energy storage system of 70 MW / 140 MWh and a 25 MW cogeneration plant with gas-fired internal combustion engines, connected at 110 kV in the existing CET-Nord substation.
A strategic project. It is included in the list of strategic investment projects and is critical for energy security.
A prepared site. The 110 kV connection, the gas pipeline from the transmission network, the environmental approval and the technical concept are in place.
What it brings to the system. Stability for the transmission grid and heat for district heating in Bălți.
How it works
The battery and the gas engines connect to the same 110 kV substation at CET-Nord. Pick a mode to see which way the energy flows.
At night, between 00:00 and 06:00, the battery charges from the grid through the 110 kV substation, at up to 70 MW.
In the evening, between 17:00 and 21:00, the stored energy goes back to the grid. 140 MWh means two hours of operation at the full 70 MW.
The battery gives or absorbs power within seconds, in either direction, when the grid is out of balance, and helps to hold the voltage.
The gas engines generate electricity for the grid, and the heat recovered from them goes to district heating in Bălți.

01
The battery charges at night, between 00:00 and 06:00, and delivers in the evening, between 17:00 and 21:00.
02
It gives or absorbs power within seconds when the grid is out of balance, and holds the voltage.
03
The gas engines produce electricity and heat; the heat goes to district heating in Bălți.

Becomes the holder of the capacities of 70 MW of storage and 25 MW of generation.
The installation and the concrete platforms, at its own expense.
The cogeneration plant and the BESS system, owned by ESCO-VOLTAJ.
Delivers energy to the grid and heat to CET-Nord in the cold season.
Clears the site at the end of the partnership.
The site, the 110 kV connection, the gas pipeline, the utilities, the existing approvals and the technical concept.
It makes use of the connection approval without investing itself, with income from access and from the energy delivered, plus heat.
Services
Battery storage systems for producers and industrial consumers, including through the existing transformer substation.
Design, equipment supply and construction: solar parks, power networks, transformer substations.
LED lighting, LV/MV power networks, thermal installations and waste-heat recovery.
