Indiana AI Boom to Consume 7 Billion Gallons of Water Annually
Amazon's "Silicon Heartland" investment prolongs fossil fuel era in small Great Lakes communities
Amazon’s massive $29 billion investment to turn Northwest Indiana into a "Silicon Heartland" is driving a resurgence in fossil fuel infrastructure and intensive water consumption. New natural gas turbines and aging coal plants are now poised to consume nearly 7 billion gallons of water annually to power the region's expanding AI data center campuses.
Key details
In Wheatfield, Indiana, state regulators have approved the construction of two new natural gas-fired turbines to support a $7 billion Amazon data center installation. These turbines alone are estimated to draw 23 million gallons of water daily from the Kankakee River, with approximately 16 million gallons — or 5.8 billion gallons annually — being consumed rather than returned to the watershed.
When combined with the requirements of the existing R.M. Schahfer Generating Station, which is being kept operational to meet surging AI power demands, the total indirect water cost reaches nearly 7 billion gallons per year. This volume is equivalent to the annual water supply of approximately 64,000 American homes. Furthermore, by 2040, experts anticipate that more than one-fifth of Indiana’s entire energy capacity will be dedicated solely to data center operations.
Why this matters
The Indiana expansion illustrates the "indirect" resource footprint of AI, where the primary environmental impact occurs at the power generation level rather than the data center site itself. The massive water draw from the Kankakee River threatens local water availability and ecological health in a region already struggling with industrial pollution and wetland loss.
Context
This development follows a broader trend where tech giants seek out regions with favorable tax incentives and available land, often at the expense of local resource stability. While some states have moved to restrict data center growth, Indiana has embraced the industry, granting utilities first-of-its-kind authority to generate energy specifically for data centers while keeping carbon-intensive coal plants online indefinitely to meet the load.
Risks and open questions
The prolonged operation of the Schahfer coal plant raises significant health and environmental concerns for local residents. Testing has already shown that the plant’s coal ash landfills have contaminated local groundwater with carcinogenic heavy metals. There are growing fears that the massive new water withdrawals and construction activity could exacerbate the spread of these contaminants through the region's shallow, flood-prone aquifers.
What happens next
Construction on the new natural gas turbines and the $7 billion Amazon facility is expected to proceed under the state's expedited energy policies. Environmental groups and local residents are likely to increase their scrutiny of water permits and groundwater monitoring as the Kankakee River begins to bear the full weight of the "Silicon Heartland" expansion.
