Grid capacity is becoming a limiting factor for data center expansion, with connection requests increasingly outpacing available infrastructure. As utilities introduce curtailment requirements and “bring your own power” models, operators must rethink how power is sourced, managed, and deployed.

This Cummins whitepaper outlines how onsite generation can support growth in constrained grid environments, balancing reliability, compliance, and operational flexibility. It explores the trade-offs across diesel, natural gas, and battery systems, alongside the architectural and regulatory considerations shaping deployment decisions.

From demand response participation to hybrid power system design, the paper provides a practical framework for aligning onsite generation strategies with evolving grid conditions and long-term capacity planning.
