Samsung SDI is poised to launch production of lithium iron phosphate (LFP) battery cells in the United States during the third quarter of this year. According to updates from the company, demand for these battery cells is projected to outpace production, underlining robust interest in US-made energy storage components.

US LFP battery cell timeline
Samsung SDI’s LFP battery project marks a key expansion in the US stationary storage supply chain. The company plans to begin production of lithium iron phosphate battery cells during the third quarter, offering a domestic alternative to overseas LFP cell sourcing. As LFP chemistry becomes an increasingly preferred solution for utility-scale energy storage developers, timelines for new US cell lines are closely watched by both storage integrators and power project investors.
The anticipated start in the third quarter of 2024 addresses a central challenge for storage developers: the reliability of the supply chain for both cost-competitive and domestically sourced battery cells. LFP cells are favored for large-format installations due to their combination of safety, lower cost, and adequate cycle life for grid-scale energy storage applications. Samsung SDI’s announcement positions it alongside a handful of cell manufacturers racing to operationalize US capacity in response to domestic content preferences and tax incentive provisions.
Market participants, including renewable IPPs and battery integrators, are expected to seek allocations from the first wave of production to meet domestic content requirements for the Inflation Reduction Act’s Section 45X incentives. The third-quarter launch is therefore significant for head-to-head competition with other market entrants and for buyers calibrating project delivery timelines.
Demand outpacing initial supply
Samsung SDI has indicated that initial demand for its US LFP cell output will outstrip available production, a trend that underscores the pressure on the North American energy storage supply chain. This imbalanced supply-demand dynamic is being driven by the scale and speed of utility-scale storage procurement in multiple US ISOs, where interconnection queues and offtake commitments have grown rapidly in the past two years.
Developers and integrators will likely face allocation constraints, especially as project backlogs and construction timelines hinge on confirmed battery supply. For institutional buyers and asset managers, securing offtake from early production batches could be critical for projects targeting near-term commercial operation dates. The demand outlook may also inform upcoming procurement strategies, as buyers assess contingencies in light of possible supply shortfalls.
Samsung SDI’s positioning reflects wider market realities, including the acceleration of bidding and long-term contracting for US-manufactured battery components. Capacity reservation practices may become more prominent as buyers look to lock in cell supply and pricing well in advance of project notices-to-proceed.
Strategic context for US storage
LFP battery technology continues to gain market share in the US storage sector, replacing legacy chemistries in many new grid-scale deployments. The ramp-up of American LFP cell manufacturing is driven by regulatory incentives, supply chain risk mitigation, and industry demand for price stability in long-duration storage.
The US government’s emphasis on domestic content for tax credits, as outlined in the Inflation Reduction Act, has increased the attractiveness of local sourcing. This benefits manufacturers like Samsung SDI who can bring US-based cell production online in time to meet federal and state project incentive deadlines. It also supports the supply resilience required for multi-year utility procurement programs.
In broader context, expansion of LFP production supports efforts to rebalance global battery supply away from China-dominated sources. US developers, grid operators, and investors are thus closely monitoring production milestones, as firm delivery of LFP cells becomes a key gating factor for timely storage deployment in wholesale electricity markets.
Implications for project procurement
The emergence of US-based LFP cell production is central to compliance with evolving project finance criteria, including offtake eligibility for tax credits and debt underwriting. Developers are recalibrating procurement to align with the timeline for domestically manufactured batteries, and the market’s response to Samsung SDI’s production capacity will influence contract structures and risk-sharing mechanisms for upcoming storage projects.
Certain project sponsors may prioritize contracting with firms whose cells are eligible for domestic content adjustments, aiming to maximize return on investment by pairing tax credit uplift with supply chain certainty. The expectation that demand exceeds initial supply may lead to higher premiums on US LFP cells compared to imported alternatives, at least through the first waves of production expansion.
How developers and utilities adapt procurement strategies, be it through long-term supply agreements, framework contracts, or joint-venture procurement platforms, will shape both near-term project delivery and the competitive landscape for battery integrators through 2025 and beyond.
What this means for buyers
Samsung SDI’s move to begin US LFP battery cell production in the third quarter signals a tightening domestic supply environment that will impact storage project timelines and procurement decisions. Buyers pursuing new projects should actively monitor cell allocation, contract timing, and domestic content compliance to secure supply and capture tax incentives. The expectation of demand outstripping initial output emphasizes the importance of early engagement with manufacturers. Project planning and offtake strategies may require adjustments as US-based supply becomes an increasingly important lever in project financing and delivery risk management.
