Data center power supply plans
LG Energy Solution announced a strategy on October 26 to make power supply for artificial intelligence (AI) data centers a new source of growth. The company intends to expand its business structure beyond battery manufacturing into power infrastructure.
LG Energy Solution identified data center power supply solutions using energy storage systems (ESS) as a core new business that day. As rapidly increasing demand for AI computing makes a reliable power supply essential, the company plans to enter this market using battery manufacturers' storage and discharge technology. The company also explained that it plans to offer differentiated solutions by applying cell design technology and power management expertise accumulated through electric vehicle battery production to ESS products.
AI data centers consume far more electricity than conventional buildings to perform large-scale computing. According to the International Energy Agency (IEA), electricity consumption by data centers worldwide continues to rise, and growth in power demand is accelerating as servers dedicated to AI computing proliferate. Establishing a reliable power supply system is considered an important task because demand concentrated at particular times or power outages can interrupt services. LG Energy Solution explained that ESS can act as a buffer between power plants and data centers in these circumstances.
An ESS stores electricity and supplies it when needed, helping stabilize voltage and frequency when power supply and demand are unstable. For data center operators, it offers the advantage of keeping servers running without interruption even during outages or periods of peak power demand. In particular, observers note that AI computing servers experience sharp, instantaneous fluctuations in electricity consumption depending on their workload, making it difficult for the grid alone to accommodate such variations. LG Energy Solution plans to use this technological expertise to establish its position as a data center power solutions supplier.
Industry demand and power supply needs
Industry observers expect battery manufacturers to continue expanding into the power infrastructure market. As electric vehicle market growth slows, the AI data center power market is considered an attractive alternative for battery manufacturers seeking new sources of demand. An official at the Korea Battery Industry Association explained that the ESS market is emerging as a new source of support for the industry as demand for electric vehicle batteries slows. A battery industry representative said, "As data center power demand increases, demand for power stabilization using ESS is also growing."
A research fellow specializing in electricity said, "With AI server expansion outpacing grid expansion, storage facilities such as ESS can act as a buffer for power supply," adding, "More companies will apply battery manufacturers' production capacity and technological capabilities to data center power solutions." The researcher added, "For data center developers, grid expansion takes years, so more are initially adopting ESS, which take relatively less time to install."
Global technology companies are exploring various ways to secure the electricity needed to operate data centers. Some are building their own generating facilities or signing long-term supply contracts with utilities, while others are moving toward hybrid power systems that include ESS. In South Korea, continued construction of new data centers, particularly in the Seoul metropolitan area, has made power supply reliability a regional issue. A KPX official said increasing data center power demand was leaving some regions with limited spare power supply capacity. LG Energy Solution is understood to have developed a strategy to secure both data center operators and utilities as customers in response to this demand.
Kim, 41, who works in electrical facility design, said, "Data centers are expected to operate continuously, 24 hours a day, so their power reliability requirements are much higher than those of ordinary industrial facilities," adding, "More projects are designing ESS as part of their regular operating systems rather than as emergency power sources." Kim added, "When a battery manufacturer also directly supplies power solutions, responsibilities during installation and maintenance are clearer."
Expansion into power infrastructure
An LG Energy Solution representative said, "We will address the data center power stabilization market by combining our existing battery production capabilities with power management technology," adding, "We will continue working to expand our business beyond electric vehicle batteries into power infrastructure."
The strategy announcement is seen as an attempt by a battery manufacturer to expand across power infrastructure rather than remaining focused on supplying automakers. Other battery manufacturers are also showing signs of increasing the share of their ESS businesses as electric vehicle battery demand weakens. The Ministry of Trade, Industry and Energy has previously mentioned the need to update regulations to stabilize power supply and demand for data centers, while related industries are watching whether power infrastructure investment can become a new area of growth for the battery industry. Industry representatives said they were monitoring whether the data center power market could become a new revenue source for battery manufacturers.
The AI data center power supply market remains at an early stage, and no further details on contract values or supply schedules have been disclosed. LG Energy Solution said it plans to announce detailed business plans in stages.
