US data center firm QTS is planning to expand further into Europe with a new campus outside Milan in Italy.In the US, the firm has been named as the operator behind a large-scale development in Alabama.QTS has also detailed potential projects in Iowa and Texas, and topped out a data center in South Carolina.The company this week pulled out of the gigawatt-scale PW Digital Gateway data center scheme in Northern Virginia, ending a battle over the site that has raged for years, but shows no sign of slowing its activities elsewhere.QTS eyes former IBM site outside Milan for three-building campusQTS is planning a campus in Vimercate, a commune 25km north of Milan in the province of Monza and Brianza in the region of Lombardy.The project, which is listed as ‘in consideration’, would see the redevelopment of a 277,800 square meter (three million sq ft) industrial site. Up to €2.3 billion ($2.6bn) could be invested.Three buildings totaling around 220MW will be constructed on the site. Work could begin as soon as this year for a 2028 launch, according to local press.The site was previously home to an IBM campus dating back to the 1960s that has since been demolished. IBM used to manufacture computing systems at the plant until it was sold to Celestica Italia in 2000. Celestica closed the plant in 2007, selling the land and buildings to BAMES and SEM, which in turn closed the remaining IBM offices there around 2014.Real estate investor Kryalos, in which QTS owner Blackstone has a stake, is also involved in the project. News that Kryalos was seeking to develop a data center in Vimercate surfaced earlier this year.The project is awaiting approval from the Italian Ministry of the Environment (VAS).QTS eyes Clinton and Howard CountyAnother project on the QTS ‘in consideration’ page is located in Clinton, Iowa.“QTS is exploring the development of a data center facility in the Clinton area to support digital infrastructure used by businesses and organizations across the country,” the company said.Plans are apparently “still in the very early stages,” and QTS said an initial site plan will be available when submitted to the City of Clinton.QTS said the site will use a closed-loop cooling system to reduce water use, adding that the company will pay for all project energy infrastructure and that there will be no cost impact to existing Alliant Energy customers from this project if it moves forward.Local press reported last month that the company is looking to develop on 1,100 acres of private land north of US Highway 30, near Clinton’s airport. News of the project first surfaced in May, and the city recently decided against introducing a moratorium on data centers.The company also lists plans to develop in Howard County, Texas. Few details are available, but the company is looking to develop on land outside Big Spring. News of the project surfaced this week.QTS behind Project Marvel in AlabamaIn a busy period for QTS, the firm has also confirmed it is the company behind Project Marvel, a planned gigawatt-scale data center campus in Bessemer, AlabamaNews of Project Marvel first surfaced back in March 2025, with an unnamed company looking to develop a $14.5 billion, 18-building data center project spanning 700 acres. The company later filed for a 900-acre expansion, taking the site to 1,600 acres and up to 1.2GW of capacity across 18 buildings.Located just outside of Birmingham, which is one of Alabama’s main data center hubs, Bessemer is a city in Jefferson County.TPA Group had taken the site through planning and reportedly sold the site for $871 million in recent weeks.Bessemer City named QTS as the company behind Project Marvel this week. QTS now lists a campus in Bessemer as in development.“QTS Data Centers is pursuing plans for a proposed data center campus in Bessemer, Alabama. We look forward to the opportunity to build a long-term partnership with the City of Bessemer, Jefferson County, and the broader community as planning progresses, the company told local press.QTS tops out in South CarolinaAnd finally, QTS has topped out its latest data center building in York County, South Carolina.Contractor Gilbane announced the news this week, marking the completion of the structure of the building.“This milestone marks continued progress on our York data center campus and supports efficient execution and strong project outcomes,” said Jacob Bryant, VP, development, QTS. “Our investment in South Carolina supports the growth of critical digital infrastructure and positions us to meet increasing demand from our customers, while continuing to engage with and support the local community.”First announced in 2023, QTS is developing a 400-acre site and aims to invest $1 billion in the project. Up to nine buildings are planned across three phases.“Reaching this milestone reflects the strong coordination and commitment across our entire project team,” said Evan Synstad, VP, Gilbane Building. “Our team remains focused on working with our trade partners to deliver this work safely and support the York community throughout construction.”
