• The campus was to be the developer’s first with onsite generation
• Plans propose six data centers and one substation on 633 acres adjacent to an OG&E substation
• Cloverleaf plans to scale the project to at least 1,033 acres and 1.4 GW

Cloverleaf Infrastructure has dropped onsite energy generation from its plans for the USD 1bn, up to 1.4 GW proposed data center campus in Piedmont, Oklahoma.

The Nvidia-backed developer has removed a 300 MW natural gas peaker plant on the proposed site from the project plans – an endeavor that would’ve been the developer’s first project with onsite generation.

“As we work with the Piedmont City Council, plans for the project continue to evolve in response to feedback and discussions with City leaders,” according to an emailed statement from a Cloverleaf representative to NPM.

Plans for Project Open Sky include the construction of six data center buildings and one substation on 633 acres in Canadian County, adjacent to the Oklahoma Gas and Electric (OG&E) Mathewson Substation.

The initial six-building development is expected to require about 600 MW, and Cloverleaf is working with Cimarron Electric Cooperative and the Southwest Power Pool on power studies and transmission infrastructure.

Long-term plans call for expanding the campus to at least 1,033 acres and 1.4 GW of power demand, with a plan for 594 MW of contracted grid-connected generation and another 900 MW to be developed across three sites near the Mathewson Substation.

The project is expected to be developed over four to seven years, and its final footprint is subject to local approvals, technical design and project phasing.

At full buildout, it is estimated to generate USD 13m in annual property taxes and create about 300 permanent jobs, while the initial phase is expected to generate USD 9m in annual energy-related revenue for Piedmont.

Cloverleaf has also committed up to USD 10m in community investments.

Project Open Sky has been met with significant pushback from the community, with four-hour meetings continuing at least twice since the end of August, delaying city council’s official consideration.

Council is again set to consider Cloverleaf’s land use requests needed to advance the project on Sept. 28.

Cloverleaf is also separately pursuing 337 additional acres in the adjacent Kingfisher County, which the developer has described as an alternative path for the project if the Piedmont proposal does not advance.

During a prior council meeting, Cloverleaf Chief Development Officer Aaron Bilyeu said Cloverleaf will continue planning for the Kingfisher County while Piedmont considers the project.

The city of Piedmont spans Canadian and Kingfisher counties.

NPM is tracking seven planned, under construction or operational Cloverleaf data center projects.

Additionally, NPM interconnection queue data shows both Canadian and Kingfisher counties have eight planned power projects totaling more than 1.2 GW.
