The Kazakhstan-Primus Power – Flow Battery Storage System is a 25,000kW energy storage project located in Astana, Kazakhstan. The rated storage capacity of the project is 100,000kWh.

The electro-chemical battery energy storage project uses flow as its storage technology. The project was announced in 2015.


The Kazakhstan-Primus Power – Flow Battery Storage System is owned by Samruk-Energy (100%), a subsidiary of JSC Sovereign Wealth Fund “Samruk-Kazyna”.

The key applications of the project are electric energy time shift, renewables energy time shift and resiliency.

Contractors involved

Samruk-Energy is the owner. Primus Power is the technology provider for the project.

Additional information

The Energy Storage System is funded by I2BF Global Ventures. As part of the multi-year agreement, Samruk-Energy plans to purchase Primus systems totaling 25 MW/100 MWh representing 1,250 batteries. These Primus systems will be assembled inside Kazakhstan and help the country reach its renewable energy goals of 30% by 2030 and 50% by 2050. Primus Power has raised a $25 million Series D round, led by a group of investors that wants to try its technology out at megawatt scale in Kazakhstan.
