LS Energy Solutions is the latest energy storage technology provider to launch modular all-in-one battery energy storage system (BESS) units for the utility-scale, as well as commercial and industrial (C&I) markets.
Two models are available of the new AiON Energy Storage System (AiON ESS) products: one for 1-hour duration applications called the Power Series and another configurable for 2 to 4-hours, called the Energy Series.
Using the company’s fourth generation of string inverters, housed in a single enclosure with lithium-ion batteries from Tier-1 providers, the systems are factory pre-assembled. LS Energy Solutions claimed the solutions are easy to use and require minimal installation work.
Both Power and Energy Series systems are operable from 220 VDC up to 1350 VDC, equipped with thermal management including HVAC and can be augmented with the addition of new enclosures that will be shipped without string inverters. They are designed to run in ambient temperatures of -5 degrees Celsius to 55 degrees Celsius and up to an altitude of 3280ft above sea level.
Power Series units come with 0.88MW rated power each and 0.94MWh rated AC energy, made with Samsung SDI lithium-ion batteries.
Energy Series units have between 0.5MW to 1MW rated usable power each and either 2.57MWh rated AC energy using SK li-ion batteries or 2.31MWh using Samsung SDI batteries.
The manufacturer said the two models are suitable for applications from smaller C&I to utility-scale installations requiring many hundreds of megawatts.
“The AiON-ESS builds on our previous generational solution to provide our customers with a factory-produced and integrated product that eliminates the need for complex on-site labor,” LS Energy Solutions CEO Steve Fludder said.
“The AiON-ESS container includes everything needed for fast and seamless installation, while the different storage configurations can meet a variety of energy needs.”
North Carolina, US-headquartered LS Energy Solutions was created through the acquisition of US motion and control tech manufacturer Parker Hannifin’s grid-tied energy division in 2018 by LS ELECTRIC, a subsidiary of South Korean conglomerate LS Group. CEO Fludder joined the company in 2020 after several years heading up NEC Energy Solutions — which has just recently been acquired by another Korean group, LG Energy Solution.
Fludder said the new products build on the LS Energy Solutions experience as “pioneers” in energy storage since 2008, having evolved since the Parker Hannifin days from “executing projects to delivering products”.
The product launch brings LS Energy Solutions into an arena of competition with the likes of Tesla’s Megapack, Wärtsilä’s GridSolv Quantum, Saft’s Intensium Max, Leclanché’s LeBlock, Powin Energy’s Stack range and the Fluence Cube, all of which are factory assembled modular ESS solutions for larger-scale applications launched within the last couple of years.
