Roswell Park Cancer Institute Main Substation Replacement

The Roswell Park Comprehensive Cancer Center provides the latest diagnostics, technologies, and therapies to more than 46,000 patients annually. The 29-acre campus relies on its own substation to supply power. A replacement was crucial to the aging electrical service infrastructure to improve the system's reliability, automatic functions to support redundancy, self-healing, real-time metering, and system recovery/service restoration after a service interruption.

CHA meticulously coordinated the design and construction process to prevent power supply disruptions that adversely affect the facility's patients, multi-million dollar research activities, and critical operations. An enhancement to the substation building included extending its footprint to incorporate an adjacent fenced-in area. CHA designed the addition with independent structural systems and ensured the height did not exceed that of the original building. Through careful planning of the substation replacement, the project was executed smoothly without any nuisance outages throughout its duration.
