A Department of Energy analysis reveals that the Inflation Reduction Act has catalysed $52 billion in announced battery manufacturing investments across 34 US states since passage, creating a projected 78,000 direct manufacturing jobs. The 45X Advanced Manufacturing Production Credit, which provides $35/kWh for domestically produced battery cells, has been the primary driver of investment decisions.
Geographic Transformation
- Southeast Corridor: Georgia, Tennessee, and Kentucky account for 40% of announced capacity, leveraging automotive supply chain proximity
- Great Lakes Region: Michigan and Ohio attract cathode and anode material production, building on existing automotive manufacturing expertise
- Battery Capacity: Total announced US cell manufacturing capacity now exceeds 1.2 TWh by 2030
“The Inflation Reduction Act has fundamentally redrawn the map of global battery manufacturing. The United States is now the fastest-growing battery production region in the world.”—Secretary Jennifer Granholm, US Department of Energy
