Amazon data center plans could bring a potential $5 billion investment to Greater Cincinnati.
The proposal involves about 601 acres near Trenton in Butler County.
Amazon Web Services, the cloud computing division of Amazon, is negotiating a major data center project in Butler County. The Cincinnati Business Courier first reported the negotiations on Aug. 11, citing public statements from local administrators and elected officials.
The proposed site covers about 601 acres south of Trenton. The property sits in Madison and St. Clair townships near Wayne Madison Road and Hawkins Road.
The land stretches toward Augspurger Road and the Great Miami River. Much of the property currently consists of farmland and undeveloped land.
The project remains under negotiation. Local officials have discussed annexing the property into Trenton as part of the development process.

Amazon data center proposal takes shape near Trenton
The Amazon data center project could include 18 buildings, according to public statements reported by Local 12. Each building could measure about 220,000 square feet.
That would put the proposed development at roughly 4 million square feet across the 18 buildings. The final design, however, could change as negotiations and approvals continue.
The project would sit just south of Trenton. It would also be close to another major data center development already moving forward within the city.
Local 12 reported that the proposed Amazon site lies northeast of the existing Prologis data center project. That project involves four buildings within Trenton’s city limits.
Trenton has already positioned portions of its southern area for industrial development. The city’s development information says the area south of Trenton has an Industrial General designation.
The city also says its 2050 comprehensive plan identifies land south of Trenton for industrial uses.
Amazon data center negotiations began earlier this year
The Amazon data center discussions became public before the latest reports about the potential $5 billion investment.
Trenton City Council meeting minutes from May show that Amazon Web Services had contacted the city. City Attorney Nick Ziepfel described the discussion as preliminary at that time.
He said AWS had expressed interest in some territory involved in a proposed annexation. He also emphasized that the city did not yet have a specific Amazon proposal in May.
The latest reporting indicates that those preliminary discussions have advanced into negotiations. The project would require additional local decisions before moving forward.
The city is pursuing annexation involving land currently located in Madison and St. Clair townships. That process could determine how the proposed development proceeds.
Local residents have raised questions about the effects of multiple large data centers in the area. Trenton council meeting records show residents have expressed concerns about water, power, traffic, noise and emergency services.
Those concerns could become part of future discussions as the Amazon data center proposal moves through the approval process.
Amazon data center expansion follows major Ohio investment
The proposed Greater Cincinnati project would fit into Amazon Web Services’ broader expansion across Ohio.
AWS announced in December 2024 that it planned to invest $10 billion in Ohio. The company said the investment could expand its infrastructure to as many as eight new sites across the state by 2030.
AWS identified Fayette County as the first of those new sites. The company planned to invest about $5 billion there to establish new data centers.
AWS now says its planned data center expansion in Ohio could exceed $23 billion by 2030. The company describes that figure as one of the largest private investment commitments in Ohio’s history.
The company’s Ohio expansion focuses on cloud computing and artificial intelligence infrastructure. Growing demand for AI services has increased the need for large-scale computing capacity.
Amazon says its Ohio data center investments will create hundreds of AWS jobs. The company also expects thousands of additional jobs to receive support through its supply chain.
The company’s Ohio investment overview provides additional information about its data center and infrastructure expansion.
Amazon data center could add to region’s technology growth
A $5 billion Amazon data center would represent a significant addition to Greater Cincinnati’s growing technology infrastructure.
Data centers provide the computing capacity behind cloud services, online applications and artificial intelligence systems. They require large amounts of land, electricity, telecommunications infrastructure and supporting facilities.
Amazon has already established a substantial technology presence in Ohio. The company says it has invested more than $70 billion in the state since 2010.
Amazon also reports that its Ohio operations support more than 35,000 full- and part-time employees. Its broader investments include logistics facilities, renewable energy projects and cloud infrastructure.
The company says its planned Ohio data center expansion will support technical positions such as data center engineers, network specialists and engineering operations managers.
It also expects the investment to support jobs in telecommunications, facilities maintenance and electricity generation.
For Greater Cincinnati, the proposed development would expand the region’s presence in the data center industry. It would also place another large-scale technology project in Butler County.
Amazon data center raises infrastructure questions
The scale of the proposed Amazon data center also creates infrastructure questions for local officials and residents.
Large data centers need reliable electricity and high-capacity telecommunications connections. They also require extensive road, water and stormwater infrastructure during construction and operation.
Trenton residents have already raised questions about those issues during public meetings. City records show concerns about stormwater, utilities and other infrastructure connected to data center development.
Residents have also questioned the cumulative effects of multiple data centers. Those concerns include potential impacts on traffic, water, power, noise and emergency services.
The city has responded by providing information about data center development on its website. Trenton says modern data centers use sound-attenuating equipment and that emergency generators remain subject to Ohio Environmental Protection Agency regulations.
The city’s development information also says data centers can create additional jobs in supporting industries. However, the final economic impact of the proposed Amazon project remains uncertain.
Amazon data center still needs local approvals
The proposed Amazon data center has not reached the final development stage.
The negotiations must continue before the project can move through the necessary local processes. Annexation represents one important issue because much of the proposed site currently sits outside Trenton.
The city’s earlier meeting records show officials were still discussing annexation and Amazon’s interest in May. The latest reports now provide more details about the potential size and investment.
The Cincinnati Business Courier reported that the project could involve about $5 billion in investment. Local 12 also reported the 18-building configuration based on public statements from officials and administrators.
Neither source indicates that Amazon has formally announced the project as a completed commitment.
That distinction remains important as local officials consider the proposal. The project’s size, investment level and final timeline could change during negotiations.
For now, the proposal places Trenton at the center of another major data center development in Greater Cincinnati.
What happens next with the Amazon data center?
The next steps will likely focus on negotiations, annexation and local development approvals.
Officials will also need to address infrastructure questions as the project advances. Those discussions could include utilities, roads, stormwater management and other services.
The proposed site covers about 601 acres. Its potential 18-building campus would make it one of the largest data center developments connected to the Greater Cincinnati region.
The project also comes as Amazon expands its Ohio cloud infrastructure to meet demand from artificial intelligence and other digital services. AWS says its Ohio data center expansion could surpass $23 billion by 2030.
For Trenton and Butler County, the proposed Amazon data center could become a major economic development project if negotiations result in an agreement.
For residents, the coming approval process will provide more information about the project’s infrastructure needs, local impact and development timeline.
The Amazon data center proposal remains under negotiation, and additional details could emerge as Trenton continues its discussions with AWS.
