South Korea’s Doosan Heavy Industries will install a 70MWh standalone energy storage system at its own facilities in Changwon, as well as a smaller battery installation co-located with solar PV.

Back in September, Energy-Storage.News reported that Doosan Heavy Industries had executed a rooftop solar-plus-storage project at the facility. Doosan issued an update to say that this - originally announced as 300kW of PV coupled with a 1MWh battery – is now going to be a 3.5MW solar power station with an 8MWh energy storage system (ESS), although a release implied this capacity would be developed across the Changwon HQ and a plant in Gunsan run by Doosan affiliate, Doosan Infracore.

This week, Doosan Heavy said it has signed a contract with SK E&S, a Korean energy developer and supplier focusing on clean energy and LNG, for an ESS facility which will deal with onsite power demand management. Doosan is responsible for supplying the storage system, while SK E&S is handling “investment and operation” for the project. It is thought the project will help reduce the facility’s use of grid electricity during peak times.

Doosan also said it is supplying controls software and engineering services and will design, supply equipment and materials and construct the system too. The 70MWh system is scheduled for completion by September 2018. The two project partners will also look at developing factory-based microgrids, creating what Doosan called a FEMS (Factory Energy Management System) to go with a solar power plant. Doosan Heavy also said it has signed a contract for commercial and industrial (C&I) for solar and storage supply to a Korean SME, BSS.  

Doosan Heavy is also the owner of US energy storage and grid software specialist Doosan GridTech, which has been busy with projects including the energy storage system at Beacon Solar Plant in California for the Los Angeles Department of Water and Power (LADWP).

Doosan GridTech, acquired by the Korean group in 2016 and rebranded from its former name, 1Energy Systems, supplied advance control software to the Changwon projects also and signed a contract a couple of months ago to work on an ESS project at a substation with 130 year-old Michigan energy company Consumers Energy. The project, in Kalamazoo, Michigan, will be supplied with a 1MW / 1MWh turnkey ESS by Doosan GridTech,  

South Korea’s market for energy storage is currently booming, including centrally-procured grid-scale systems for the country’s main utility and grid operator KEPCO, opportunities in heavy industry for reducing C&I customers costs and a supportive government incentive programme. The country is also home to major advanced battery manufacturers including LG Chem, Samsung SDI and Kokam.
