Status Header
BlueOval Battery Park Michigan | Marshall, Calhoun County, MI | BlueOval Battery Michigan LLC (wholly owned Ford subsidiary) | ~20 GWh LFP prismatic | CATL technology license
Ford's language (2026-06-17): Assembling full LFP prismatic cells; past "initial pre-production battery cells"; undergoing CATL production-verification testing; "on track to ship electric vehicle batteries in 2026."
DOT characterization (2026-09-03): "Operational," production "commenced."
Assessed status: Pre-commercial production testing. Ford has disclosed no commercial shipment, accepted GWh, production rate, yield, or utilization figure. On the publication's evidence hierarchy, Marshall clears equipment installation and qualification testing but not commercial production. Duffy's "operational" runs ahead of Ford's own most recent disclosed milestone.
The Ledger
2023-02-13 — Original announcement
Stated: Ford announced a $3.5B wholly owned LFP cell plant at ~35 GWh annual capacity, 2,500 employees "to start," initial production 2026, using "LFP battery cell knowledge and services provided by CATL."
Observed: The Michigan Strategic Fund approved a Critical Industry Program grant — Michigan's discretionary cash incentive for large manufacturing projects — of up to $210M against $3.5B invested and 2,500 qualified jobs by 2027-03-31. Total package value approximately $1.035B.
Gap: None. Stated plan and state commitment aligned.
2023-09-25 — Construction pause
Stated: Ford said it was "pausing work and limiting spending on construction" until confident the plant could be operated competitively.
Observed: No WARN notice filed. Consistent with a pre-construction pause at a site that had no production workforce to separate.
Gap: None actionable.
2023-11-21 — Restart and downsizing
Stated: Construction would resume while Ford "re-timed and resized" the investment. Revised plan: ~20 GWh, 1,700+ jobs, 2026 production start. Ford did not quantify the capital reduction.
Observed: Capacity down 43%. Employment commitment down 32%. The revised capital figure stayed undisclosed for a further eighteen months.
Gap: Two of the three headline parameters were restated within nine months of announcement; the third — capital — was not.
2024-07-09 — Construction progress and incentive revision
Stated: Ford said the plant was approximately 20% complete and on track for 2026 production, and returned roughly 230 acres to the local development authority.
Observed: The Michigan Strategic Fund replaced the original incentive package the same day. Base grant fell from $210M to $141M (against $2.5B and 1,700 jobs), with up to $166M available at $3B and 2,100 jobs. The 15-year Renaissance Zone — a state property and business tax abatement — was rescinded. Ford-specific incentive value fell from approximately $1.035B to $384–409M.
Gap: Incentive value was cut by more than 60% against a capacity cut of 43%. Both the progress update and the incentive revision carry the same date.
2025-06-23 — Structure complete, equipment arriving
Stated: On a media tour, Ford said the building structure was complete, the project was approximately 60% complete overall, and production equipment was making sample cells off-site ahead of installation at Marshall. BlueOval Battery Michigan CEO Scott Davis put investment to date at $3 billion. Lisa Drake said equipment sourced from China would be Ford-owned, with Ford holding "full control of the production."
Observed: Reporters on-site confirmed structure completion. Sample cells were being produced off-site, not at Marshall. The $3B figure was Ford's first stated capital number after the downsizing, and it does not reconcile with the state's latest verified figure of $1.41B in qualified investment as of 2025-09-30. Two plausible reasons for the spread: the state's verification cycle lags actual spend, and "qualified investment" under the grant agreement may exclude categories Ford counts. Neither party has publicly explained the $1.59B difference.
Gap: Physical milestone confirmed. Investment figure not verifiable from public records.
2025-12-15 — Residential energy storage application added
Stated: In an SEC-filed release, Ford said Marshall would also build smaller-amp-hour cells for residential energy storage alongside the previously announced EV prismatic cells. The same release projected roughly $19.5B of companywide special items from product and manufacturing reallocation, allocated none of it to Marshall, and kept Marshall cell manufacturing on a 2026 schedule.
Observed: No line count, no capacity split between vehicle and storage cells, no revised site capacity. The 20 GWh nameplate figure was left unchanged.
Gap: That 20 GWh now spans two cell formats serving different applications. Absent a disclosed allocation, it cannot be carried into a model as an EV cell supply figure.
2026-06-17 — Full cells assembled at Marshall
Stated: Ford said 500+ employees were assembling full LFP prismatic cells through slurry mixing, coating, formation, aging and final inspection. The plant was "ready to ramp" and "on track to ship electric vehicle batteries in 2026." Targets: 800 employees by year-end, 1,700 eventually.
Observed: No disclosed commercial shipment, accepted volume, GWh output, yield, utilization or run rate. The state's most recent performance report, covering data through 2025-09-30, showed 146 self-reported non-temporary jobs and $0 disbursed under the Critical Industry Program grant. Ford's 500+ headcount stands at 29% of the 1,700 commitment. As of 2026-09-11, Ford's careers page listed 25 open Marshall positions, weighted toward production supervisors, maintenance technicians and quality operators — the mix an active ramp generates.
Gap: Ford's language points forward: "ready to ramp," "on track to ship." What is confirmed is end-to-end cell assembly inside the building. Commercial acceptance, sustained output and customer-qualified shipment are all unconfirmed, which places Marshall alongside every other facility surveyed in the publication's US Addressable Cell Supply Inventory: none has yet publicly shown production, quantified output and buyer availability at the same time.
2026-09-03 / 2026-09-08 — DOT Secretary Duffy's characterization
Stated: Secretary Duffy called Marshall "operational," said production had "commenced," and objected to Ford's use of CATL technology on national-security grounds. The letter is dated September 3 and was posted publicly during the Labor Day week. It contains no tax determination, no adjudication under the prohibited foreign entity (PFE) provisions of §7701, no enforcement order, and no instruction to halt production.
Observed: Ford responded that the CATL arrangement was "a limited technology-licensing and services agreement" and that Marshall was "neither a joint venture nor a foreign-owned manufacturing operation." Ford's own most recent operational disclosure, from June 17, describes production-verification testing and future shipments. The license agreement has not been published, and Ford has not specified CATL's contractual authority over process changes, equipment specifications, quality release, data access or personnel. Congressional committees asked for those terms in September 2023 and again in January 2026. No public Ford response containing contract detail was identified.
Whether CATL's licensing role amounts to "effective control" under §7701 is a question about contract terms, not about public statements. Until those terms are disclosed, the question is not resolvable from the outside — by Duffy or by anyone else.
Gap: "Operational" exceeds Ford's own disclosed milestone. The effective-control question under §7701 matters commercially because it runs in two directions: a PFE finding would bear on Ford's own §45X production credit for cells made at Marshall, and separately on the FEOC-compliance status under §30D of any vehicle carrying those cells. Those are distinct assessments with distinct claimants. Duffy's letter is a policy objection, not a compliance determination, and does not settle either one.
Supplementary signals — no divergence identified
- WARN Act: No notice naming Ford or BlueOval Battery Michigan in Michigan's public WARN records, 2023–2026. Consistent with a site that reduced future hiring commitments rather than separating existing workers.
- DOE LPO: No conditional commitment or closed loan for Marshall in DOE's public portfolio. The $9.63B BlueOval SK loan covers Kentucky and Tennessee.
- SEC filings: Ford's 10-K and 10-Q filings from Q1 2023 through Q2 2026 contain no facility-specific Marshall reference — no allocated capex, impairment, or restructuring charge. The plant-level financial picture rests entirely on operating communications, not audited filings.
- 45X credits: No public Ford disclosure of §45X claims or eligibility expectations for Marshall was identified. There is no public registry of facility-level 45X claims for any US plant.
- Equipment suppliers: Ford has said the equipment was imported from China and is Ford-owned, but has not named the manufacturer. No supplier order references naming Marshall were found in publicly available earnings materials.
- Satellite/aerial imagery: Not assessed for this entry.
Trajectory Assessment
Through June 2026 the record is internally consistent. Ford described pre-commercial milestones in pre-commercial language, and the observable evidence supported those descriptions. The divergence in this audit enters from outside the company: a cabinet secretary applying "operational" to a plant whose operator describes verification testing and planned shipments.
Two figures remain unreconciled. Ford's $3B investment claim and the state's $1.41B verified figure sit $1.59B apart, with $0 of grant money disbursed as of the last state reporting date. Definitional differences between qualified investment and Ford's capital accounting probably explain part of the spread; nobody has said how much. Headcount, by contrast, is clean and trackable — 500+ against 800 by year-end against 1,700 eventually, with 25 postings open this week.
For a reader modeling domestic LFP cell availability, two things follow from the entries above. The 20 GWh nameplate cannot be used as an EV cell number, because since December 2025 it has covered residential storage cells as well and Ford has not split it. And Marshall's credit-eligibility status cannot be assessed from public documents at all, because the determining terms sit in a license agreement withheld through two congressional requests over three years.
If that disclosure pattern holds, the stated shipping window closes later this year without the public record gaining the output figures or the eligibility finding that a sourcing or compliance decision would require.
Last verified: 2026-09-11
- PFE interim guidance deadline: Treasury must issue PFE safe-harbour tables and associated guidance by December 31, 2026, which would determine whether Marshall's CATL licensing structure can be evaluated against a published standard rather than an undisclosed contract.
- DOE BESS threshold decisions: The September 9 bulk-power-system RFI asks what voltage, capacity, and criticality thresholds should govern whether BESS falls within the new grid-security regime — answers that could create a second compliance layer for Marshall's residential energy storage cells.
- Ford Glendale conversion timeline: Kentucky's September 10 restatement of Ford's plan to convert the former EV-battery plant to at least 20 GWh of BESS production by late 2027 adds a second Ford LFP facility whose CATL-technology exposure and PFE status will face the same undisclosed-contract question as Marshall.
- State incentive verification lag: Michigan's latest performance report covers data only through September 2025, so the next annual report should show whether Ford's qualified investment and job count have closed the gap toward the $2.5B and 1,700-job thresholds that trigger CIP disbursement.
