Sentinel Data Centers, a developer and operator of enterprise colocation data centers, has brought online North Carolina’s first dedicated transmission voltage substation for use by a multi-tenant data center.

Engineered and constructed similarly to Sentinel’s NJ-1 69kV substation in the NY/NJ region, Sentinel NC-1’s 100kV substation can support up to 50MW of capacity in a 2N configuration, with redundant service via separate feeds from diverse 230kV utility switching stations. In addition to enhanced reliability, Sentinel Data Centers’ new transmission voltage substation would facilitate more attractive occupancy economics.

“The resiliency profile of the new NC-1 substation materially enhances our core offerings to the most discerning large enterprises,” said Todd Aaron, Co-President of Sentinel Data Centers. “Our ability to provide a truly differentiated utility solution resonates deeply with those users who require 100% uptime and appreciate the fundamental underpinnings of high availability.”

The new substation also enables Sentinel’s Transmission+ product set, an “infrastructure-light” solution that would leverage transmission-quality utility distribution to provide high availability levels using less infrastructure and at a lower cost. Transmission+ load blocks can be deployed granularly allowing Sentinel’s end-users to match cost structures with resiliency requirements on a workload-by-workload basis.

Low Power Costs

“Multi-tiered data center solutions remain a widely unmet need in the colocation space,” said Paul Hines, Vice President of Operations & Engineering at Sentinel Data Centers. “The inherent reliability in our transmission voltage utility service permits flexible infrastructure tiering that can easily match tenant application requirements, while maintaining high availability.”

The substation build took place over a 24-month period, during which time Sentinel Data Centers collaborated with Duke Energy on designing and constructing the 100kV substation. Through Duke Energy’s new OPT-V rate, which incentivizes high voltage and large loads, Sentinel’s NC-1 facility would realize among the lowest power costs in the eastern US.

Since its inception, Sentinel has developed more than 1.6 million square feet and 120 megawatts of multi-tenant and build-to-suit data center solutions for a diversity of Fortune 500 enterprises across multiple industries, including financial services, healthcare, technology and biotechnology.
