A new case study from PXiSE profiles the complex Slate utility-scale solar + storage facility which features five solar PV plants, integrated battery energy storage systems, and five distinct power purchase agreements (PPAs) all funneled through a single point of interconnection (POI). PXiSE’s Renewable Power Plant Controller manages the 300 MW facility through a configuration of secondary controllers at each of the five plants, overseen by a primary controller ensuring POI compliance.
