Applications Rolls-Royce Power Systems Protects Underground Data Center In 2015, Cavern Technologies doubled its footprint to meet the needs of its growing client base. The 120,000-square-foot colocation facility meets the power, cooling and security requirements of more than 100 of the region's leading companies. The company's latest expansion of 60,000 square feet required MTU Onsite Energy backup power that would support the facility's increasing power needs, while offering the flexibility, scalability and expandability needed to support future expansions. Located in a limestone cave 125-feet beneath Lenexa, Kansas, Cavern Technologies offers built-to-suit private data suites to some of the nation's leading health care organizations, financial services institutions and tech companies. Taking their servers underground, these collocating enterprises are protected against weather by a natural rock bunker five times stronger than concrete that accommodates their specific space, power and connectivity requirements. Mounting Demands Designed to support small, medium and large enterprise customers, Cavern opened its data center doors in 2007. Seven years later, the company embarked on a 60,000-square-foot expansion that brought its total operating space up to 120,000 square feet, with 100,000 square feet more space available for expansion. Having uninterruptible power supply is not optional. To power its new footprint, Herron turned to Central Power Systems & Services, an authorized MTU Onsite Energy distributor in Kansas, Missouri and the Oklahoma Panhandle. Paul Chaponniere led the project for Central Power, whose partnership with Cavern has spanned many years. Through Photo - Central Power Systems and Services close collaboration, Herron and Chaponniere customized three MTU Onsite Energy Series 1600 DS500 500 kWe backup diesel generators for the subterranean data center's specialized needs. Units were installed in December 2014, each outfitted with a tailor-made master control panel (MCP) and set to run in parallel. The system is designed for proper load and complex function management from an integrated single source and allows Cavern Technologies to deliver on its customer guarantee of beyond 99.995 percent uptime. System Reliability The Series 1600 generator set provides reliability, high power density and fuel efficiency in the 250 kW to 600 kW power range. Generators feature an MTU engine engineered specifically for gen-drive applications and an outlet box designed to incorporate the breaker and control panels in one streamlined package. This design allows flexibility to switch the control panels and breakers to the right or left depending on the need and allows the mainline circuit breaker to be installed in a compartment on the right or left side per customer specification. The outlet box can accommodate multiple mainline circuit breakers, utilizing both compartments. Data center customers can typically specify fewer generator sets for applications, depending on the size of the installation. This is because MTU Onsite Energy diesel generator sets are certified at an 85 percent average load factor over 24 hours. Nothing Left to Chance Although inherent redundancy was built into the Cavern systems with the three units in parallel operation, MTU Onsite Energy created a custom master control panel for Cavern Technologies to add an additional layer of reliability. The best modern generator sets are computer-controlled to decrease likelihood of system failure. Generator set controllers provide system control, metering, protection, fault-alarm-status indication, event recording, system-auxiliary drive controls and programmable logic in a simple, easy-to-use package designed to ensure readiness of the standby system when needed. "To a great extent, reliability can be designed into generator sets, transfer switches, switchgear and control systems to increase the likelihood that they function as intended," said Jerhod Smithback, electrical engineering manager at MTU Onsite Energy. "The flexibility and structure of Cavern's master control panel is an example of this and stands out as an engineering highlight of the system." Power in Aggregate With an eye toward future growth, an additional four units will soon join Cavern Technologies' three existing generator sets. At full capacity, a total of seven 500 kWe will power the data center. In the existing paralleling environment, the four additional generators will install and configure seamlessly thanks to Cavern's MCP, while leaving capacity to scale up even more as power demands grow.
