Tesla Reportedly Agrees $2.11B Deal with Samsung SDI

Reports say Tesla has agreed to pay roughly $2.11 billion (about 3 trillion won) to South Korea’s Samsung SDI for ESS batteries over three years. The batteries are said to be for Tesla Energy products such as Megapack and Powerwall — not for electric vehicles — and some industry reports estimate supply could be about 10 GWh per year with Samsung SDI converting certain U.S. LFP lines, though those details remain unconfirmed. Samsung SDI has said nothing has been finalized and Tesla did not comment, leaving the arrangement unofficial for now. If confirmed, the deal would add a second major non-Chinese supplier for Tesla Energy (after a prior $4.3 billion LFP agreement with LG) and help meet rising ESS demand. Tesla’s energy division has been expanding rapidly, reporting roughly 44% growth and about $3.4 billion in revenue in the cited period, with Megapack deployments reportedly growing faster than EV deliveries.
