Blacknight BK0 is a 24,165 sq ft data centre in Barrowside Business Park, Graiguecullen, Carlow. It provides 2 MW of IT load via an on-site ESB substation, with a design power density of 20 W per sq ft. Cooling relies on free-air economisers for most of the year, backed up by N+1 mechanical chillers on warmer days, targeting a PUE of 1.1 to 1.2, and redundancy is ensured through multiple utility feeds and N+1 cooling capacity.

The site is carrier-neutral, offering diverse fibre routes and multiple carrier options. Security features include 24‑hour CCTV, biometric and card‑access controls, and ISO/IEC 27001:2022 certification, with continuous monitoring of temperature, humidity and smoke detection systems in place. Phase 1 opened on 3 February 2014 after a €1 million investment announced in August 2012; further capacity has been provisioned at the substation but not yet deployed.
