7 M M M M Establish Hierarchy AU D IT Micro-Manage Audit Capture Network Updates Accurately capture all the ing Points present in the network and place them in a logical hierarchical tree. Micro-Manage Audit by introducing more Levels in the hierarchical tree. Capture and update the hierarchical tree in case of any Network changes such as Network Extension, Switching, etc.

9 M M M M Establish Hierarchy Problem Statement: Accurately capture all the ing Points present in the network and place them in a logical hierarchical tree. Solution: For each present in the DB, use backtracing to find its Parent (Non- Consumer).

11 Post-GIS Pre-GIS Level Feeder Level DT Level Level Feeder Level DT Level Division Level Boundary Level Nodal Level Switching Level

12 AU D IT Micro-Manage Audit Problem Statement: In the Existing levels of Hierarchy the Inspection Area (Area of Focus) is too big. This is resulting in higher rates of Resolution Time Solution: Introduce more layers (i.e. s) into the Hierarchical Tree in order increase the number of Audit Sections thereby reducing the Area of Focus.

16 Problem Statement: Capture Network Updates Update the Hierarchical Tree in case of any Network Changes such as Network Extensions, Network Switching, etc. Solution: Since all changes made to the network are routed via Business Process, update the Process Flow to trigger Energy Audit extract whenever Network Changes are captured.

17 Enhanced Reliability Since the Data is extract only after going through multiple layers of QAQC, the reliability of Energy Audit Reports is greatly enhanced Reduced Processing Time Introduction of Additional layers have drastically reduced the Timelines associated with locating the issue Scalable Solution Solution is designed in such a way that any augmentation to the network (big/small) can easily be captured and passed on to the hierarchical tree. Completely Automated The triggering, extraction and delivery hierarchical tree is completely automated thereby eliminating any chance of userrelated error.
