Tesla has reportedly struck a multi-year deal with Samsung SDI to acquire more than $2 billion in energy storage system (ESS) batteries over the next three years, according to sources cited by Korea Economic Daily.
The agreement reflects growing ambitions and competition in the global battery market as automakers and tech companies pivot toward large-scale storage solutions.
While no official confirmation came from either company, industry insiders say the order totals over 3 trillion won, signaling Tesla’s aggressive expansion in the non-automotive energy sector.
The deal was reported by a major business daily in South Korea, and quickly echoed by global news agencies as battery markets responded.
What Does the Tesla–Samsung SDI Deal Entail?
This deal covers the procurement of large-format ESS (Energy Storage System) batteries, designed primarily for grid-scale storage, utility projects, and Tesla’s own energy storage product lines.
The order amount reportedly exceeds $2 billion, to be supplied over three years. Such volume makes it one of the sector’s top deals in recent years, bringing together Tesla’s scale and Samsung SDI’s manufacturing prowess.
Samsung SDI is expected to deliver advanced battery modules suitable for applications ranging from power grid backup to renewable energy integration.
For Tesla, the agreement strengthens its supply chain by adding a premium battery partner for critical storage projects worldwide.
Did you know?
Samsung SDI is heavily investing in the development and eventual mass production of all-solid-state batteries, often called the "dream battery" for EVs due to their potential for higher energy density and improved safety. They completed a pilot line for these in 2023.
How Will ESS Batteries Shape Tesla’s Energy Strategy?
Tesla’s ambitions in energy extend well beyond electric vehicles. Energy storage is a key business pillar, covering utility-scale Megapacks and industrial Powerpacks.
Deploying Samsung SDI’s batteries is expected to aid in ramping up production capacity, supporting more installations in the U.S., Europe, and Asia.
With a consistent ESS battery supply, Tesla can accelerate projects supporting grid stability and renewable integration
mission-critical in regions with high solar and wind generation. It also helps Tesla stay competitive with other major ESS providers, including LG Energy Solution and CATL.
What Drives the Surge in Global Energy Storage Demand?
The global shift toward renewable energy has increased the urgency for reliable battery storage. Fluctuating solar and wind outputs require flexible storage technologies, making ESS batteries indispensable for power companies and regulators alike.
Market researcher Wood Mackenzie recently projected a doubling of global battery storage demand by 2030.
Policy moves and national decarbonization targets also propel ESS investments.
In the United States and Europe, financial incentives and grid modernization programs have flooded the market, while Asia-Pacific utilities seek to enhance supply reliability amid rapid electrification trends.

Is This Supply Pact a Game-Changer for Battery Makers?
Samsung SDI’s win is significant in an industry where gaining large contractual volume with Tesla signals performance, safety, and innovation leadership.
Analysts suggest such deals often set the tone for future tendering processes across the globe, with suppliers racing to meet quality and sustainability metrics.
For Tesla, diversifying its battery lineup means reducing risk and supporting more flexible engineering choices.
The Samsung SDI partnership may also spur further competition among Asian battery giants to secure global dominance in ESS supply.
What Factors Influence Execution and Future Prospects?
One key variable remains official confirmation. As of press time, Samsung SDI stated that “nothing has been finalized,” and Tesla has not commented, reflecting the competitive sensitivity of such negotiations.
If the deal is realized, focus will shift to delivery timelines, supply consistency, and on-the-ground project rollouts.
Currency fluctuations, sourcing of critical materials, and regulatory hurdles may affect pricing and execution.
But the broader message is clear: as grid operators and large energy buyers seek robust solutions, landmark supply pacts like this lead the global ESS transition.
The coming years could see even larger contracts as battery-makers ramp up capacity to meet accelerating demand for clean energy storage.
Whether this deal is the first of many or a unique one-off, all eyes are on Tesla and Samsung SDI to see how quickly their ambitions will be reflected in energy markets worldwide.
