Amazon Web Services (AWS) has received the green light for its planned data center campus in Marysville, Ohio.

As reported by Columbus Business First, the company received a reinvestment area agreement from the Marysville City Council on March 10 for a campus with two data center buildings. The company has committed to investing $1 billion in the data centers.

Marysville is in Union County, outside of Columbus.

The campus will be located on 55 acres of land in Marysville Innovation Park at 14684 Industrial Parkway. AWS plans to build two data centers spanning a total of 500,000 sq ft (46,450 sqm). An application was filed by AWS for the project last month.

As part of the "reinvestment area agreement," Marysville has awarded AWS a 30-year, 100 percent property tax exemption based on the assessed value of the data centers.

Construction is slated to begin this August, and be completed in 2027.

“We are proud to reinforce our long-term commitment to the state of Ohio with plans to expand AWS cloud infrastructure in the city of Marysville,” Roger Wehner, vice president of economic development at AWS, said. “Working with state and local leaders, we look forward to investing in the local community, strengthening its local workforce, enhancing educational opportunities and contributing to the city’s long-term growth."

AWS will also provide $15 million annually to the Marysville Exempted Village School District and the city over 15 years, and other community support projects.

Marysville city manager Terry Emery added: "This investment by AWS represents a significant step forward for Marysville and Union County. It reinforces our city’s ability to attract leading technology companies and showcases our commitment to fostering economic growth and job creation.”

The Marysville campus, also known as Project Cosmo, has been on the cards since at least October 2024 when AWS filed a rezoning application.

AWS has been investing significantly in Ohio, with the company previously stating it has spent more than $10 billion on digital infrastructure in the state in the last decade.

In 2023, AWS said that it planned to invest an estimated $7.8 billion by the end of 2029/2030 in data centers in Ohio. Around $3.5 billion of that is expected to go to New Albany, where it announced plans to build a five-building data center campus.

The company is also planning developments in other parts of Ohio. In November last year, Amazon announced plans to build a $2 billion data center campus in Sunbury in Central Ohio. The company purchased land for the project at the end of December.

Another campus in Fayette County in Southern Ohio, is also planned by AWS. News of the data centers first surfaced in November, with the company acquiring 590 acres in Jefferson Township last month. Local filings suggest the campus could go live in 2026.
