The IRA Two Years In: What Actually Got Built

The Investment Numbers

By mid-2024, IRA-related manufacturing investment announcements exceeded $250 billion in committed private capital. The major categories:

• Electric vehicle and battery manufacturing: ~$110 billion announced, concentrated in Tennessee, Georgia, Kentucky, North Carolina, Michigan, and Ohio.
• Solar manufacturing: ~$25 billion announced, concentrated in Georgia, South Carolina, Texas, and Arizona.
• Wind and offshore wind: ~$15 billion announced, mostly along the Atlantic coast and in upper Midwest manufacturing.
• Critical minerals processing: ~$8 billion announced for lithium, graphite, nickel, and rare-earth processing facilities.
• Hydrogen: ~$12 billion in the seven regional clean-hydrogen hubs.

Construction starts have run behind announcements. Production ramps run behind construction. The 2024 production has been modest; the 2026-2028 period is when the announced investments translate to visible manufacturing output.

Specific Project Cases

Hyundai Metaplant Georgia: $5.5 billion EV and battery facility near Savannah. Construction began in 2022; limited production began in late 2023; full production targeted for 2025. The facility is producing both Hyundai and Genesis EVs and serves as the test case for whether IRA-driven investment can build at the announced scale.

Form Energy West Virginia: $750 million iron-air battery facility near Weirton, West Virginia. Construction began in 2023 on the site of a former Weirton Steel mill. The facility will produce long-duration energy storage for grid applications. The location was a deliberate attempt to demonstrate that the IRA's "energy communities" bonus could direct investment to former coal-and-steel regions.

Q Cells Dalton: Hanwha's $2.5 billion solar manufacturing expansion in Dalton, Georgia. The facility produces solar cells, modules, and ingots at vertically integrated scale that was previously concentrated in Chinese manufacturing. The IRA's 45X manufacturing tax credits have made the economics work.

Each of these is a partial success story. None of them was at operational scale by 2024. The question is whether the announced projects will deliver at the projected scale and within the projected timelines, and whether the IRA tax credit revenue can sustain through the production years.

The Treasury Rulemaking

The IRA delegates substantial rulemaking authority to the Treasury Department. The most contested rules:

Section 30D (consumer EV credit): the domestic-content and "foreign entity of concern" rules determine which EVs qualify for the $7,500 consumer credit. The Treasury's 2023 guidance has been revised multiple times under pressure from various interests. The Korean manufacturers were briefly excluded, then included. The Chinese content rules have been progressively tightened. The current implementation excludes most pre-2024 EVs from the credit but includes most domestically assembled new models.

Section 45V (clean hydrogen credit): the rules governing what counts as "clean" hydrogen have been one of the most contested rulemakings. The "three pillars" approach (incrementality, time- matching, deliverability) determines whether hydrogen produced from the grid qualifies. Treasury's January 2024 proposed rule favored the strict three-pillars approach; industry lobbying has pushed for looser interpretation; the final rule remains unresolved.

Section 45X (manufacturing credit): the rules for which components qualify and at what credit values determine which sectors get the strongest incentives. The current rules favor battery cells over modules, solar wafers over panels, and processed critical minerals over raw extraction. The distinctions matter for which firms can profitably operate in the US versus continue offshore.

The Geographic Distribution

The Brookings tracking work has documented that announced investment skews toward Republican-leaning states. South Carolina, Georgia, Texas, Tennessee, Alabama, and North Carolina together account for over 40% of announced IRA manufacturing investment. The pattern is partly accidental (where energy projects make economic sense) and partly deliberate (the "energy communities" bonus directs investment toward former coal regions, many of which are Republican-leaning).

The political-economy strategy is that Republican legislators will defend IRA spending in their own districts, even if they would prefer not to vote for it generally. The strategy is testable: will the sitting Republican legislators in affected districts actually defend the spending if the program comes up for repeal? The early evidence suggests yes — multiple Republican senators have written letters to Treasury asking for favorable implementation in their states even while voting against the underlying legislation.

The WTO Challenges

The IRA's domestic-content requirements have produced WTO complaints from the EU, Korea, and Japan. The European Commission has been the most active critic, arguing that the credits effectively discriminate against EU-produced vehicles and components. The dispute-settlement process is slow enough that the cases are unlikely to produce decisive rulings before the IRA has been operating for several years.

The US response has been a combination of (a) negotiating bilateral agreements with allies (the US-EU Critical Minerals Agreement under discussion is the major example), (b) modifying Treasury rules to accommodate allied production, and (c) accepting that some allied firms will simply build in the US to qualify. The pattern is one of incremental accommodation rather than full retreat from the domestic-content framework.

The Risks Going Forward

Several risks could constrain the program's success:

• Political: an administration change could implement the rules in ways that reduce program effectiveness without requiring legislative repeal.
• Fiscal: the actual cost has run substantially above the original $369 billion estimate, partly because the credits are uncapped and demand has been higher than projected.
• Operational: announced investments may not deliver at projected scale. Some of the early announcements have already been delayed or downsized.
• Trade: the WTO complaints and bilateral conflicts could constrain the program's design over time.
• Industry capture: as the tax-credit revenue flows to specific firms, the firms may push for rule modifications that benefit them at the cost of program effectiveness.

The Two-Year Verdict

The IRA at the two-year mark has produced substantial private investment commitments, has shifted measurable manufacturing capacity toward US sites, and has built political coalitions that may make the program durable across administration changes. The actual production output remains modest because of construction lead times. The 2027-2028 period is when the empirical test will be conclusive: either the announced projects deliver at scale, or they do not, and the political coalition for further industrial-policy investment will follow accordingly.
