Tesla and LG Energy Solution have signed a $4.3 billion battery supply agreement tied to Megapack production in the United States, according to a March 16 Reuters report and a U.S. government statement. The deal highlights how grid-storage demand is pulling more battery manufacturing into domestic supply chains.
Utility-scale battery storage prices in the U.S. fell sharply in the first quarter of 2026 even as distribution-scale pricing leveled off, a sign that suppliers are tilting toward larger projects for data centers and independent power producers.
Noon Energy says it has successfully operated a scaled-up long-duration energy storage system for thousands of hours, with some tests exceeding 200 hours. The milestone strengthens the case for multi-day storage as data centers and clean energy developers look for alternatives to short-duration batteries.
