The landmark legislation has sparked a new wave of clean energy manufacturing. This database tracks major IRA-linked investments for projects in electric vehicles, solar and more on a monthly basis.

Editor’s Note: Amid the Trump administration’s review of the Inflation Reduction Act, many companies are reevaluating their investment plans for clean energy projects in the U.S. As Congress weighs the future of the IRA’s many tax credits and manufacturers consider the merits of their planned investments, we’ve taken a pause on updating this tracker.
Across the U.S., companies continue to invest billions of dollars in clean manufacturing projects as they pursue lucrative tax credits offered under the Inflation Reduction Act. The law, passed in August 2022, has helped spur a new era in U.S. manufacturing, with factories popping up in dozens of states to produce items such as electric vehicles, batteries and solar panels.
In the first year of the law’s existence, 39 states saw factory and other project announcements worth more than $86 billion. Since then, companies have continued to invest amid the Biden administration’s push to expand the country’s clean manufacturing industry and bring supply chains closer to home.
Tracking projects spurred by the IRA across states and clean energy sectors can help manufacturers better understand which states and regions are leading the investment wave.
Manufacturing Dive is monitoring these investments on a monthly basis and highlighting key trends in the data in a series of charts, including where investments are clustering across the U.S. and which foreign countries’ companies are leading in establishing projects.
We’ll be updating the data in these charts each month, based on the latest investment summaries from environmental group E2, which has been logging project announcements since the passage of the IRA.
Read on for five charts that break down what you need to know about clean energy manufacturing investments in the U.S. For the latest monthly data, scroll to the bottom for a breakdown of projects by investment, job creation, sector and location.
Investment by state: North Carolina leads the nation
Investment by sector: EV and battery projects dominate
Projects by region: The South is a hub for investment
Foreign investment: South Korea, Japan-based firms top the chart
Projects by month: Investments spiked in March 2023

December had three clean energy projects across three states, the lowest number seen since the IRA was enacted. One was a foreign-based electric vehicle project from an Austria-based company called Benteler.
The projects totaled an investment amount of nearly $300 million and are expected to create 500 jobs.
