First In The World
LSIS, a leading Korean electrical components manufacturer, has won the world’s first certification for its megawatt energy storage systems (ESS), from Underwriters Laboratories (UL), a U.S.-based global certification company. Accordingly, the company is seeking to enter the U.S. ESS market, which is rapidly growing by expanding new renewable energy generation and replacing outdated transmission networks with smart grid systems.
LSIS said on April 4 that it has received the UL 1741, which is a necessary product safety certification to tap into the U.S. power market, for its power conditioning system (PCS) for the one-megawatt ESS.
Demand for ESS runs high in the U.S. market, as not only the federal government but also the state governments are expanding new renewable energy generation and making massive investments in energy-saving ESS systems in a bid to minimize greenhouse gas emissions and modernize outdated electrical grids with smart grid technologies after the United Nations Climate Change Conference in Paris last year.
In particular, the PCS market in the U.S. alone is worth US$275 million (315 billion won) this year, and will grow 45.8 percent each year to US$4.87 billion (5.58 trillion won) by 2024. LSIS expects to increase its share in the North American market with the UL certification and technical competitiveness. Accordingly, the company plans to put up a good show in the market of medium capacity with 100 to 500 kilowatt as well, based on its business performance capability and technology in the large-scale ESS sector.
LSIS already completed the development of PCS products for the U.S. market in August last year. PCS helps control both alternating current (AC) and direct current (DC), stably connecting the ESS and the power system. It is regarded as a core technology that constructs the ESS, along with a battery.
Connecting the new renewable energy generation stage of with the power system conversion stage, the one-megawatt ESS made by LSIS is a solution that maximizes the power quality by adjusting the frequency before the end user receives power.
