B&W Picks Siemens Energy to Deliver Steam Turbine Gensets for Data Center Project

Siemens Energy was selected by Babcock & Wilcox (B&W) to supply steam turbine generator sets for the Applied Digital project, in which B&W will deliver 1 GW of power for an AI Factory. The companies signed a limited notice to proceed (LNTP) to secure the turbine gensets, allowing B&W to deliver power by year-end 2028. The complete contract release is expected in Q1 2026.

“Teaming with Babcock & Wilcox and Siemens Energy—both global market leaders with many decades of experience—ensures we have the proven technologies and trusted expertise needed to meet our aggressive timelines,” said Wes Cummins, Chairman and CEO, Applied Digital. “This agreement gives us confidence that we can deliver the capacity needed to support the next generation of AI infrastructure, and we look forward to working with the teams from both of these companies.”

Previously, B&W signed an LNTP with Applied Digital to design and install four 300-MW natural gas-fired power plants with boilers and associated steam turbines. The company will also sign an ongoing parts and services contract to support the AI Factory once commercial operation begins. A proven plant configuration will help to satisfy the project’s accelerated schedule: A gas-fired boiler generates heat and steam to drive the turbines, producing reliable and dispatchable energy.

“This arrangement brings together two companies with long histories of innovation and leadership in the power generation industry,” said Kenneth Young, B&W Chairman and Chief Executive Officer. “Leveraging Siemens Energy’s advanced turbine technology alongside B&W’s proven boiler systems positions us to meet critical schedule milestones and deliver reliable power by the end of 2028.”

B&W’s solutions for AI and other data centers leverage proven technology to provide reliant, redundant, and readily available power. The company’s relevant project experience comes with thousands of boiler designs and installations worldwide at utility and industrial plants. Deploying its expertise in engineering, technology, construction, and project management, B&W ensures a fully integrated solution from design through operation.

“Our selection of Siemens Energy is a key step in delivering efficient, reliable power for our customer, Applied Digital, and the rapidly growing AI data center market,” said Brandy Johnson, B&W Chief Technology Officer. “We can deliver data center solutions significantly faster than what could be achieved with simple-cycle or combined-cycle power plants.”

Wet Gas Scrubbing

In December 2025, B&W received a $40 million contract to deliver and install advanced low-pressure wet gas scrubbing (WGS) technology at a major petroleum refinery in Canada. The WGS system controls SO₂ emissions from fluid catalytic cracking and fluid coker units, allowing refiners to comply with environmental regulations. With enhancements, it may also control NO_x and particulate emissions, furthering the technology’s approach to emissions compliance.

The WGS system features high SO₂-removal efficiency and low-pressure operation to minimize energy consumption. Its customizable designs accommodate challenging site layouts, while its integration with NO_x and particulate control technologies reinforces comprehensive compliance. B&W is an authorized licensee of ExxonMobil’s WGS technology, which has been successfully deployed in many refinery applications globally. In September 2025, the Canadian refinery customer placed a $10 million order and this WGS installation represents an additional $30 million commitment with B&W.
