Rolls-Royce Expands U.S. Generator Assembly Capacity
MANKATO, Minn. — Rolls-Royce has expanded its U.S. manufacturing footprint with the opening of a new $24 million logistics and assembly facility in Mankato that will more than double production capacity for backup power systems used in critical infrastructure.
The 250,000-square-foot center was built adjacent to the company's existing mtu power generation manufacturing facility and is designed to support increased production of mtu Series 4000 generator sets assembled for customers throughout the Americas.
The expansion adds logistics and assembly space to meet growing demand for backup power systems used in hospitals, airports, industrial facilities and data centers. According to Rolls-Royce, the investment will create more than 100 jobs, increasing the Mankato workforce by nearly 20%.
“As demand for reliable, independent energy accelerates in the U.S., this investment enables Rolls-Royce to keep pace with the market and provide mission-critical backup power generation at a greater scale than ever before,” said Jörg Stratmann, CEO of Rolls-Royce Power Systems.
Approximately one third of the capacity is dedicated to production and assembly activities. The building includes climate-controlled logistics and assembly areas, interior loading and unloading facilities, and space for future expansion.
The generator sets assembled in Mankato are powered by mtu Series 4000 engines manufactured at Rolls-Royce's facility in Aiken, S.C., where the company announced a $75 million expansion in 2025. Together, the two projects represent nearly $100 million in U.S. manufacturing investment aimed at increasing production of backup power systems.
