Why Has Indiana Become A Hotbed Of Data Center Activity?
Indiana has become a significant hub for data center development, driven by a 2019 sales tax exemption and the growing demand for AI infrastructure, attracting major tech companies. This rapid expansion has ignited statewide policy debates and local land-use conflicts, with concerns over electricity, water, and community impacts. As a result, numerous counties have implemented restrictions or moratoriums on new data center projects.
Indiana has emerged as a major center for data center development, largely due to a 2019 state sales tax exemption on qualifying equipment and electricity, making it competitive with established markets like Virginia and Texas. This growth has been further fueled by the accelerating demand for large AI facilities, leading to a more than 4,000% increase in power capacity demands since 2022.
Major tech companies, including Amazon, Google, Meta, and Microsoft, are actively pursuing projects in Indiana. Amazon Web Services, for instance, initially announced an $11 billion campus near New Carlisle, later expanding its commitment by another $15 billion. Meta is also developing a campus within the 9,000-acre LEAP Innovation District in Boone County, a project that has faced criticism regarding farmland acquisition, transparency, and water usage.
The surge in data center activity has escalated into a statewide policy debate, touching on the reshaping of Indiana's electric grid, water planning, and local land-use decisions. While the Indiana Economic Development Corp. highlights the economic benefits of such investments, critics argue that data centers create few long-term jobs relative to their intensive land, power, and water consumption, and that tax exemptions reduce local revenue. Local communities often raise concerns about noise, water, traffic, property values, and the loss of farmland during zoning hearings.
In response to these challenges, Indiana enacted House Bill 1007 in 2025, requiring large-load customers, including data centers, to cover at least 80% of the cost of increased generation. Additionally, nearly a third of Indiana's counties have moved to restrict or temporarily pause data center development, with 11 counties enacting temporary moratoriums and at least two, Marshall and Cass, implementing outright bans.
