Sabey Corp. has commissioned its massive data center building in New York City and plans to hold a grand-opening ceremony Wednesday. Technology industry leaders and government officials, including New York mayor Michael Bloomberg, are expected to be in attendance.

The company is bringing online 18MW of critical power in a market with high demand for data center capacity. The 32-story Intergate.Manhattan tower is fully dedicated to data center space and supporting infrastructure, with only two floors with space reserved for offices.

Sabey is offering both turn-key and powered-shell wholesale options in the building. Each floor plate is 35,000 sq ft. The building’s power capacity can scale to 40MW.

Seattle-based data center provider bought the Verizon building on 375 Pearl St. in 2011. While plenty of new data center space had been built out in neighboring New Jersey, Manhattan, the global business hub was strapped for modern quality data center capacity.

Sabey is not the only company to have brought new space to the market, however. DataGryd, a newcomer to the data center marketplace, has brought new space online at 60 Hudson St., a major carrier hotel where the provider is occupying four floors.

Sabey specializes in large data center campuses. The company’s four properties in Washington, its home state, range from 173,000 sq ft to 1.2m sq ft, and its campus in Ashburn, Virginia, measures 490,000 sq ft.

Sabey has talked publicly about one tenant for its new Manhattan building. In July 2012, it announced that the New York Genome Center would install computing infrastructure at the former Verizon building and at Sabey’s Quincy, Washington, data center.
