Rosatom’s Fuel Division, TVEL, and NG-Energo said on October 22 that they had commissioned an energy storage system at the Chayanda oil and gas condensate field in Russia’s Yakutia region. According to Rosatom’s Atom Media release, the system operates as part of an autonomous power plant. It is rated at 2,400 kVA of apparent power and has an energy capacity of 1,136 kWh.

The release says the storage unit provides a fast-acting power reserve and smooths short-term peaks in electricity demand. The stated aim is to partly replace spinning reserve, reduce loading on gas-turbine and gas-piston generators, and preserve their service life. The battery is designed to support the site’s power system during sudden load changes.

Rosatom says the installation reduces transient effects on generating equipment and helps the autonomous plant operate more evenly. The company says that should improve operating efficiency and create conditions for lower operating costs, but the announcement gives no quantified savings, battery lifetime or measured gain in site output.

Chayanda is described as one of eastern Russia’s large oil and gas condensate fields and a resource base for the Power of Siberia pipeline. The release cites Gazprom data estimating about 1.2 trillion cubic metres of recoverable gas and 61.2 million tonnes of oil and condensate reserves. Those are field reserve estimates cited in the company release and should not be confused with the capacity of the newly commissioned storage system.

Gazprom’s field profile places Chayanda in the Yakutia gas production centre and describes it, together with the Kovyktinskoye field, as a resource base for the Power of Siberia pipeline. Gazprom lists recoverable reserves of about 1.2 trillion cubic metres of gas and 61.2 million tonnes of oil and condensate, and annual design gas output of 25 billion cubic metres. It says the field was discovered in 1983, oil production began in 2014, and gas development began in 2015. This background explains why reliable autonomous power matters at a remote producing site, but it does not show the storage unit powers the gas pipeline itself or changes field output. The battery announcement is about the field’s isolated generation system.

The battery ratings describe two different properties. The 2,400 kVA figure is apparent power, a measure relevant to the rate at which the system can exchange electrical power; 1,136 kWh is its energy capacity, the amount it can store. Neither figure alone specifies how long the unit can sustain a given load, because that depends on operating conditions, discharge limits and system design. Rosatom describes the equipment as a fast reserve for short peaks and rapid load changes, rather than as a replacement for the site’s gas-fired generators. The company announcement does not give battery chemistry, cycle life, charge-discharge profile, cost or measured fuel savings, so those performance questions remain outside the reported figures.
