Gas and diesel generator systems provide immediate, reliable protection against utility outages—keeping data centers online during storms, equipment faults, and planned shutdowns
Why it’s essential
Even short interruptions risk data loss, SLA penalties, and reputational damage. The industry targets 99.99% uptime, so generators are core infrastructure, not a “nice-to-have.”
Diesel
Highest power density, long runtime with on-site fuel (72+ hours), proven in harsh conditions. Consider fuel storage, maintenance, and emissions compliance.
Natural Gas
Lower emissions, continuous pipeline supply, fewer on-site logistics. Consider pipeline dependency and slightly lower power density.
Key metrics
Start to full load
~10 seconds
Minimum runtime
~72 hours (with appropriate fuel strategy)
Reliability target
99.99% + routine testing/maintenance
Redundancy
N+1 or 2N architectures
Customer segments
Enterprise (private DC)
long-term reliability, TCO, integration
Colocation & Cloud
strict SLAs, scalability, documentation
Edge & Telecom
compact, fast-deploy, remotely managed
Hyperscale
standardization across sites, efficiency, sustainability, remote ops
Buying criteria
Reliability/MTBF and references, 15–20-year TCO, regulatory compliance (emissions, noise, building codes, Tier), 24/7 service and parts, and alignment with sustainability goals.
Tier alignment
Designs map to Tier I–IV requirements for redundancy and fault tolerance; Tier IV demands concurrently maintainable, fault-tolerant power paths.
