Energy storage integrator and software provider Doosan Gridtech will deliver a 20MW/10MWh energy storage system to Los Angeles Department of Water and Power (LADWP).


Doosan GridTech, with its partner, KTY Engineering, will install the system at the utility’s Beacon solar PV plant in Kern County, California.

The Beacon solar installation was selected as the site for the battery storage system due to the high concentration of solar PV. The battery will provide multiple, coordinated functions to LADWP that will help efficiently integrate solar into the grid, minimising LADWP’s use of gas‐fired generating units.

The battery will also mitigate short-term impacts of the natural gas curtailment in the area, following the Aliso Canyon natural gas storage facility leak in 2016.

In 2016 Doosan Heavy Industries & Construction acquired 1Energy Systems, renamed Doosan GridTech, which has developed an open standards energy storage controls architecture.

Doosan’s battery storage system, uses lithium ion technology and enables preventative maintenance, required in the harsh Mojave desert environment, to occur without sacrificing availability.

The Beacon energy storage plant will be Doosan Gridtech’s sixth energy storage system delivered in three years marking it as a leading provider of utility-scale energy storage systems. The turnkey systems are based on an open standards software architecture.

Turnkey supply contracts are simpler and provide a higher degree of short-term risk management, while an open standards-based software architecture ensures long-term risk management in the form of flexibility across technology and suppliers.

The storage plant will be controlled by the Doosan GridTech Intelligent Controller, one of the first software control systems built on open standard interfaces.

The intelligent controller is the ‘brains’ within the energy storage system, with intelligence to coordinate schedules and operating modes with SCADA and respond to local signals from power meters and other sources.

The software is scalable enabling LADWP to potentially expand the Beacon site up to 50MW of capacity without the need for additional control software.
