Arizona Renewable Resource Transmission Inventory Study

Arizona Public Service Company (APS) retained EPG for the Arizona Renewable Resource Transmission Inventory Study project (ARRTIS). ARRTIS convened an approximate five-month process to gather, review, and map renewable resource and environmentally sensitive data in the State of Arizona. This included the identification of areas where solar and wind resources were technically ideal for utility-scale generation development, and the definition and location of environmentally sensitive areas, including those that by statute or law would be excluded from consideration for generation facilities. Another aspect of the study was the acquisition and management of all Geographic Information System (GIS) data identified as available and relevant to the ARRTIS process. EPG staff also provided a technical review of the final ARRTIS report submitted to the Southwest Area Transmission Planning Group.
