Tesla and LG Energy Solution have agreed to build a $4.3 billion manufacturing facility in Lansing, Michigan, to produce lithium-iron-phosphate cells for Tesla's Megapack 3 utility-scale energy storage systems, according to the U.S. Department of the Interior.
Production at the facility is scheduled to begin in 2027, the agency said in a press release. The facility will supply cells for Megapack 3 systems assembled at Tesla's Houston-area Megafactory.
Tesla and LG did not immediately respond to a request for comment about the supply agreement.
The LG deal comes as Tesla sees increasing interest in its energy generation and storage production capabilities. In 2025, the company ended the year with nearly $12.8 billion in revenue within the segment, representing a 26.6% year-over-year growth rate, CFO Vaibhav Taneja told investors during the company's Q4 2025 earnings call.
"This was the result of higher deployments in all regions and continued strength in demand for both Megapack and Powerwall," Taneja said, referring to the company’s large-scale energy storage and home battery storage products, respectively. "As we look at 2026, our backlog remains strong, well diversified globally, and we expect increasing deployments with the launch of Megapack 3 and Megablock."
In its Q4 earnings call presentation, Tesla reported that it planned to begin production of Megapack 3 and Megablock at its Houston facility this year.
Meanwhile, LG, a major maker of electric vehicle batteries, also plans to expand its energy storage systems business. The company expects to book 90GWh of new grid-scale and other energy storage system orders this year and to expand its production capacity to over 60GWh, according to the company's 2025 financial results. It also said it plans to have more than 80% of its energy storage systems production capacity in North America.
LG has emphasized energy storage systems while maintaining automotive partnerships, including two multi-year EV battery supply agreements with Mercedes-Benz. However, Ford cancelled a $6.5 billion battery supply contract with the company last year as the carmaker shifts its focus away from EVs.
The latest partnership between Tesla and LG was confirmed as part of a broader package of projects meant to strengthen U.S. energy manufacturing, which included private sector commitments totaling $56 billion to secure critical energy supply chains in the U.S., according to the Interior Department. The commitments followed a meeting between the Trump administration and Indo-Pacific leaders from 17 countries.

Opening Takes

"Tesla's energy storage segment is now large enough ($12.8B, 26.6% growth) that securing LFP cell supply through 2027 materially de-risks a 30%+ CAGR thesis, but execution risk and policy dependency are underpriced."
Tesla's energy storage segment grew 26.6% YoY to $12.8B in 2025—now material enough to move the needle on consolidated margins. A $4.3B LFP cell partnership with LG de-risks Megapack 3 supply starting 2027, addressing the single biggest constraint to scaling grid storage. However, the 2027 start date is 18+ months away; near-term capacity remains bottlenecked. LG's pivot toward 80%+ North American energy storage production (away from auto) signals sector rotation, but Ford's $6.5B battery cancellation last year shows energy storage demand isn't guaranteed—it's policy-dependent and cyclical.
Devil's Advocate
The $4.3B capex commitment assumes sustained grid storage demand through 2027-2030, but if U.S. renewable subsidies weaken or interest rates spike (raising LCOE economics), utilization could crater. LG's automotive EV business is also deteriorating (Mercedes aside), suggesting the company may be over-committing to a storage bet precisely when auto demand softens.

"Tesla is successfully shifting its valuation narrative toward energy storage, but the capital intensity of this expansion creates significant execution risk that could pressure near-term cash flows."
This $4.3B investment is a strategic pivot for TSLA, signaling that the energy storage segment is no longer just a 'side project' but a core capital-intensive pillar. By securing localized LFP (lithium-iron-phosphate) supply, Tesla is de-risking against potential trade tariffs and logistics volatility. However, the market is over-indexing on the revenue growth of the energy division while ignoring the margin compression risks. Scaling Megapack 3 requires massive operational expenditure (OpEx) and integration of new battery chemistry at scale. If the 2027 production timeline slips—a common occurrence in gigafactory construction—the capital tied up in this facility will weigh heavily on free cash flow, potentially masking weakness in the automotive segment.
Devil's Advocate
The sheer scale of the $56 billion in broader U.S. energy commitments suggests an oversupply of battery capacity by 2028, which could lead to a price war and crater the margins of the very storage systems Tesla is betting on.

"Securing a U.S.-based LFP cell supply via LG materially strengthens Tesla’s Megapack supply chain and supports upside to its energy-storage growth, provided the plant ramps on time and demand for Megapack 3 holds."
This Tesla–LG deal materially de-risks Tesla’s Megapack 3 supply chain by locking in domestically produced LFP cells and ties to a major battery OEM, supporting Tesla’s growing energy-storage revenue stream (Tesla reported ~$12.8B in the segment in 2025). It also aligns with LG’s stated capacity expansion and U.S. policy momentum to onshore critical energy manufacturing. However, benefits aren’t automatic: $4.3B capex with a 2027 start date leaves multi-year execution, permitting, and ramp risks; LFP suitability and cost competitiveness for all grid use-cases vary; and increased capacity could compress cell margins if demand or pricing softens. Watch timing, throughput targets, and Megapack 3 performance.
Devil's Advocate
If Megapack 3 underperforms or utilities prefer other chemistries/pack makers, the plant could sit underutilized and add fixed-cost strain; additionally, increased North American EES capacity risks a supply glut and price competition that would erode margins.

"This deal de-risks Megapack scaling, cementing energy storage as Tesla's $30B+ revenue growth engine by 2030."
Tesla's energy storage business, which hit $12.8B revenue in 2025 (27% YoY growth, per CFO Taneja), gains critical supply security from this $4.3B LG plant producing LFP cells for Megapack 3 starting 2027—feeding the Houston Megafactory amid a 'strong, diversified' global backlog. Energy is Tesla's highest-margin segment (likely 30%+ gross margins vs. auto's teens), now ~10% of revenue but poised for 50%+ CAGR as Megapack 3/Megablock scale. Localizes supply under IRA (despite Trump admin context), de-risking China reliance. Offsets EV softness; if deployments double to 100GWh/year, justifies TSLA re-rating from 60x forward P/E.
Devil's Advocate
Megaplants like this routinely slip 12-24 months (Tesla's own record), leaving 2026 backlog at risk of shortages/erosion; $4.3B capex (LG-funded?) pressures amid ESS oversupply and LG's Ford cancellation precedent.

"Energy margin upside is real, but 2027 supply timing leaves 18+ months of backlog erosion risk, and the valuation math assumes energy scales faster than Tesla's own execution track record supports."
Grok claims energy is 30%+ gross margin and justifies 60x P/E re-rating, but that math doesn't hold. If energy is 10% of revenue at $12.8B (implying ~$128B total), even 50% CAGR takes years to meaningfully move consolidated margins—especially if auto margins compress. The 2027 start date means zero contribution to 2026 backlog relief. Nobody's addressed whether utilities actually prefer LFP for grid vs. NCA/NMC, or if Megapack 3's economics justify the capex at current wholesale power prices.

"Scaling energy storage via heavy capex will likely drive multiple compression rather than the re-rating bulls expect."
Anthropic is right to question the margin math, but Grok’s reliance on a 60x P/E re-rating is the real elephant in the room. Tesla is trading as a tech company, but this LG deal forces them into a capital-intensive manufacturing reality. If the energy segment scales, it likely drives a multiple contraction toward industrial peers, not expansion. We are seeing a shift from high-margin software-like software revenue to low-margin grid infrastructure, which the bulls are conveniently ignoring.

"Megapack's 31% gross margins make energy a margin expander, not compressor, justifying premium multiples."
Google mischaracterizes energy storage as 'low-margin grid infrastructure'—Q4'24 earnings showed Megapack gross margins at 31% (vs. auto 17%), driven by software layers and long-term contracts. LFP excels for stationary apps (10k+ cycles, fire safety) where utilities prioritize cost/durability over NCA density. This deal expands high-margin rev to 20%+ of mix by 2028, countering auto weakness—not contracting multiples.
