TC Communications Hurricane-Proofs Jamaica’s Network Case Study As a result, in early 2007 JPS commissioned a “SCADA Visibility Project” to prevent these devastating blackouts from re-occurring. The SCADA Visibility Project had two main goals: • To provide a redundant high-speed communications network that would ensure 100 percent SCADA visibility into all 69kV and 138kV substations • To provision redundant teleprotection communications for the 138kV transmission lines that connect the 9 major substations.
