Jan 13 (Reuters) - Ukraine's largest private energy

company DTEK will buy storage systems with total capacity of 200

megawatts from a unit of renewable energy storage provider

Fluence Energy ( FLNC ) to provide back-up for six power

stations, DTEK said on Monday.

Ukraine is facing an energy crisis after Russia intensified

bombardments of its energy sector, knocking out about half the

country's available generating capacity and causing blackouts

nationwide.

DTEK expects the power storage plants, located in different

sites across Ukraine, to be operational by October - before the

harsh winter season - with storage capacities ranging between 20

and 50 MW each.

In total they will supply the equivalent of two hours of

power in about half the households in the capital Kyiv, DTEK

said in a statement.

"Battery storage is a critical element in Ukraine's vision

to build a decentralised energy system that reduces our

emissions and enhances our energy security," the statement said.

"With advanced control modes, the battery-based storage

system should also enable faster restoration of power after

outages," it added.
