Question · Q3 2025
Rob Wertheimer asked for a detailed explanation of the engineering challenges and decision-making process involved in adapting Cummins' natural gas platforms for large engines suitable for prime power in data centers. Wertheimer also inquired about recent shifts in data center design, the role of backup power, and how the market has evolved over the past few months.
Answer
Jennifer Rumsey, Chair and Chief Executive Officer, explained that while Cummins possesses strong natural gas engine R&D capabilities, developing new large-engine products for data centers is a multi-year cycle. Rumsey emphasized that high reliability remains critical for data centers, ensuring backup power will persist. She noted that data centers are exploring prime power solutions, including peak shaving with existing products and stationary energy storage, as grid support becomes a challenge.
