The Ledger

2022-01-25 — Announcement

Stated: GM and LG announced a $2.6B, 2.8M-sq-ft plant to create more than 1,700 jobs, open in late 2024, and reach 50 GWh annually. Cells were intended for GM's Orion Assembly and other EV plants. Neither release named a chemistry; DOE's project description later identified the Ultium facilities as NCMA pouch-cell plants.

Observed: LG's own 2022 company profile listed Lansing at 50 GWh but placed mass production in 2025, not late 2024.

Gap: A one-year difference between "opening" and "mass production" was present from the start, and neither company defined the distinction between those milestones.

2022-05 through 2023-02 — Shell construction

Stated: DOE's supplemental environmental assessment anticipated phased equipment installation from summer 2023, trial and debugging through 2025, partial operations in 2024, full operation in 2025.

Observed: Land clearing began May 2022 per DOE records. Final structural steel was installed 2023-02-24. A Delta Township utility agreement recorded Ultium's request for initial water and sewer by mid-June 2023 for process-equipment buildout. DOE's environmental assessment was conducted for Loan Programs Office purposes, but no Lansing-specific LPO conditional commitment or closed loan was identified in the reviewed public record.

Gap: Aligned on construction. LPO loan status for Lansing specifically, as distinct from the broader Ultium JV's DOE relationship, could not be determined from public sources.

2024-07 — Construction slowdown

Stated: Ultium spokesperson Katie Burdette said construction was continuing and the building should be "substantially complete" by October 2024, with installation and scaling to follow customer demand.

Observed: Trade and local reports cited unnamed sources saying equipment work had slowed and only two of five planned production lines had been installed. An LG Chem KRX regulatory filing disclosed later described construction as having been "temporarily suspended in July 2024 because of slowing EV demand."

Gap: The company's contemporaneous language described a building nearing completion; the regulatory filing, disclosed months later, confirmed a suspension the spokesperson did not name. The two-of-five-line count remains sourced only to unnamed industry participants.

2024-12-02 — GM agrees to sell its Lansing interest

Stated: GM and LG announced a non-binding agreement for LG to acquire GM's interest in the "nearly completed" facility. GM said Lansing then employed nearly 100 people and framed the transaction as capital efficiency. GM's ownership interest in Ultium Cells LLC, which continued to own the Warren and Spring Hill plants, was unchanged.

Observed: Michigan state records counted 148 employees as of 2024-09-30, with $432.2M in building cost and $608.1M in installed equipment.

Gap: GM's "nearly 100" and the state's 148 may reflect different counting methods; the discrepancy is unresolved. $608.1M in installed equipment is consistent with "nearly completed" as a description of the building but does not establish how many production lines were operational or qualified.

2025-03-25 — Michigan incentive transfer

Stated: Michigan's transfer memorandum described Lansing as a 41 GWh plant, construction approximately 98% complete, expected to begin production in spring or summer 2025. The $120M Critical Industry Program grant was assigned to LG Energy Solution Michigan, tied to at least 1,360 qualified new jobs by 2030-12-31.

Observed: 41 GWh appeared here for the first time in the reviewed record, and the memorandum did not explain the 18% reduction from the announced 50 GWh. A separate Renaissance Zone obligation requires at least $1.5B of investment by 2027-12-31; the Michigan Strategic Fund approved reassignment of the zone to LG in April 2025.

Gap: Capacity dropped from 50 to 41 GWh without published explanation. The state's 1,360-job obligation is a different figure from LG's stated goal of up to 1,700 at full capacity.

2025-05-07 — Acquisition closes

Stated: LG said ownership transferred, construction was more than 98% complete, and manufacturing equipment was being moved into the plant.

Observed: LG's audited 2025 financials recorded the transfer at $2.154B. A KRX filing records a Lansing-specific contract for electrolyte-system flushing, process-safety-management work, and "production stabilization" running 2025-07-01 through 2026-06-30 ($458,500). A separate filing records a $21.48M contract for utility and process installation beginning 2025-09-08, with a December 2025 amendment noting work remained in progress past the original completion date.

Gap: Ownership transfer confirmed. The supplier contracts establish that substantial commissioning continued through H1 2026, consistent with "equipment being moved in" at closing and confirming the facility was not production-ready at acquisition.

2026-01 through 2026-05 — Shifting status language

Stated: LG's Q4 2025 investor presentation emphasized expanding North American ESS capacity at Lansing. The Q1 2026 presentation listed Lansing among sites "in operation" and associated it with LFP pouch and LFP prismatic formats. In May 2026, LG said pouch-battery mass production was occurring at Lansing and that prismatic LFP for Tesla's Megapack 3 would be added from 2027.

Observed: The reviewed disclosures do not define whether "in operation," "mass production," and the August "start of production" referred to different lines, different commissioning phases, or different commercial milestones. Facility-level GWh, line count, yield, and shipments were not disclosed at any stage.

Gap: Ambiguous. LG described Lansing as "in operation" by Q1 2026, producing by May, then declared "start of production" in August, using the terms sequentially without published definitions. This could reflect different lines reaching different milestones, or marketing cadence applied to a continuous ramp.

2026-08-18 — Production declaration

Stated: LG declared production began at the 226-acre facility, making large-format LFP cells for ESS through Vertech and NMC cells for Toyota vehicles. Approximately 900 current employees. Target of more than 35 GWh annually at full scale. Independently reported by Energy-Storage.News.

Observed: Consistent with the preceding equipment-installation and stabilization records. No WARN filings were identified for Lansing during the 2024-2026 transition period, though Michigan's archive may be incomplete. Active hiring for production, process, and engineering roles is visible on LG's careers site. No Lansing-specific equipment orders from Wuxi Lead, Manz, or Schuler were identified in the reviewed public disclosures; the named supplier evidence is limited to the CK Solution installation contract and the electrolyte-system stabilization contract documented above.

Gap: The declaration establishes that cells are being made. It does not disclose current GWh, utilization, yield, LFP/NMC line allocation, shipment volumes, customer-qualification status beyond the named Vertech and Toyota relationships, uncommitted capacity, or the ramp schedule to 35+ GWh.

Trajectory Assessment

The stated-observed gap at Lansing has narrowed since this publication's Issue 10 assessment, which found that LG's declared SOP at its facilities did not reach the downstream proof states: converted GWh, stabilized yield, customer qualification, accepted recurring shipments, uncommitted allocation. The production declaration, corroborated by dated supplier contracts for commissioning work, confirms the facility crossed from equipment installation into production. Workforce moved from roughly 100 to 148 at the ownership transition to approximately 900 at SOP, directionally consistent with a ramp, and the absence of WARN filings supports continuity through the JV dissolution.

Capacity moved the other way. The headline figure went from 50 GWh to 41 GWh to "more than 35 GWh" across three sources using three formulations, a reduction of up to 30% from announcement to the floor of the current target, with no published explanation attached to either revision. The product and customer base changed completely over the same period: from GM EV supply on NCMA chemistry to ESS through Vertech and Toyota EV supply on LFP and NMC. Whether that reflects the same physical lines reconfigured or different lines built to different specifications is not disclosed. The July 2024 report that only two of five planned lines had been installed, sourced to unnamed industry participants and never confirmed or updated by the company, has not been resolved by any subsequent disclosure. Current line count, and the relationship between installed lines and the 35+ GWh target, remain publicly unverifiable.

For teams evaluating Lansing as contractable domestic supply, the US Addressable Cell Supply Inventory finding from Issue 9 stands unchanged: no public record simultaneously reports current production, facility-level GWh, and quantity available to an unaffiliated buyer. Three downstream channels are now named. Vertech is captive ESS integration. Toyota is an OEM relationship for NMC cells. Tesla Megapack 3 is prismatic LFP, stated for 2027. Whether uncommitted capacity exists beyond those channels, at what volume, and on what timeline cannot be determined from public sources. The state's 1,360-job obligation by 2030-12-31 and the $1.5B Renaissance Zone investment requirement by 2027-12-31 are the next dated tests with observable outcomes.
