ZGlobal provided Lendlease with complete Generation Interconnection Procedures (GIP) Interconnection Request (IR) Forms and Technical Data submission support. These efforts included a significant level of engineering and project management, such as the preliminary design of interconnection, preparing the site plan, single-line diagram, inverter/converter, and transformer specifications, gen-tie line data calculations, facility modeling in GE PSLF format (presumes support from the inverter/converter manufacturer), and coordination with the governing utility or balancing authority (BA). Additionally, for transmission projects, ZGlobal supported the projects through the Phase 1 results review, assessment of assigned upgrades, and validation of BA cost assignments. ZGlobal also prepared the quadrangle map and associated model updates.
