ENERGEX uses Oracle Primavera to forecast network projects over short, medium, and long time horizons. They extract data from Primavera using APIs to connect it to other systems and tools. Due to the large number and value of projects, extracting ROI from Primavera requires optimizing for memory usage and database performance. Potential solutions include using the Enterprise Reporting Database, job services, scripting, splitting projects across the structure, and upgrading to 64-bit.
