LG Energy Solution Targets 50 GWh With 5 US Battery Factories

LG Energy Solution plans to bring over 50 gigawatt hours of annual battery manufacturing capacity online in the US by the end of 2026 across five facilities (MI, IL, AZ, OH, GA). The company also projects a 15% cost reduction on its next-generation cells by 2028. Tim Montague and John Weaver dig into that story and more in this May 1, 2026, edition of Clean Power Hour Live.

Tim and John cover five stories this week, drawn from industry publications and their own active projects in the field.

• LG Energy Solutions is building five battery factories with a combined capacity of 50+ GWh per year, targeting completion by the end of 2026. The company projects a 15% cell cost reduction by 2028. (Energy Storage News)
• Tandem PV began demonstration manufacturing of a perovskite-silicon module reaching 29.7% efficiency, backed by a warranty of less than 1% annual degradation over 25 years. (Solar Power World)
• On April 27, Trina Solar claimed the world record for silicon solar cell efficiency at 28%. Longi broke that record the very next day. (PV Magazine)
• The US Department of Commerce announced preliminary anti-dumping duties of 123% on solar modules from India, 35% from Indonesia, and 22% from Laos. (PV Magazine)
• Republican lawmakers introduced new legislation to extend the commercial solar ITC, which currently expires at the end of 2027. Safe-harboring by July 4, 2026, extends project runway to July 3, 2030. (Solar Power World)

The battery capacity numbers, perovskite efficiency milestones, and tariff developments covered here carry direct implications for procurement and project planning decisions in 2026 and beyond.
