LG Chem Makes Big Move In U.S. Energy Storage Market
A sign that utilities are serious about battery backups is the decision on Tuesday by AES Energy Storage, based in Arlington, Va., to buy 1 gigawatt-hour worth of inexpensive lithium-ion batteries from LG Chem Ltd. of Seoul. That’s enough electricity to power 100,000 homes in the United States.
LG Chem said it will provide the batteries for a project led by AES by 2020 in sales worth hundreds of billions of dollars, though didn’t disclose the specific value of the transaction.
AES’ plan is to package the LG batteries into large banks to provide clean electricity to a utility or a factory when other sources of energy aren’t available. These banks of batteries, also called battery farms, will use software tailored to provide energy for as little as 30 minutes or as long as four hours, depending on the need.
AES isn’t new to this kind of project. For several years it has set up energy storage systems (ESS) in the United States – in Ohio, Pennsylvania and West Virginia – as well as in Chile. All told, the companies’ existing farms so far have installed or are installing batteries with a combined capacity of about one-third of a gigawatt.
“LG Chem has succeeded in setting up a milestone by signing such a large contract for the first time in the world,” said Lee Ung-beom, the president of LG’s energy storage division. As a result, he said, LG Chem will be able to expand production of mid-size and large batteries for ESS, eventually eclipsing its production of batteries for electric vehicles (EVs), which so far has been its largest division.
