Pre-Requisite of Energy Audit = Meter Hierarchy Tree.

D Micro-Manage Audit Capture Network Updates

Accurately capture all the Metering Points present in the network and place them in a logical hierarchical tree. Micro-Manage Audit by introducing more Meter Levels in the hierarchical tree. Capture and update the hierarchical tree in case of any Network changes such as Network Extension, Switching, etc.

Initiate Back Trace from Meter Meter Encountered? Consumer Meter? Continue Back Tracing Retrieve Meter Record from DB Assign as Parent Retrieve Next Meter Record from DB No Yes Yes No

Problem Statement: Accurately capture all the Metering Points present in the network and place them in a logical hierarchical tree. Solution: For each Meter present in the DB, use back- tracing to find its Parent Meter (Non- Consumer).

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. Meters) into the Hierarchical Tree in order increase the number

Problem Statement: 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.

Capture Network Updates

Since the Data is extract only after going through multiple layers of QAQC, the reliability

• f Energy Audit Reports is

greatly enhanced

Enhanced Reliability

Introduction of Additional layers have drastically reduced the Timelines associated with locating the issue

Reduced Processing Time

The triggering, extraction and delivery hierarchical tree is completely automated thereby eliminating any chance of user- related error.

Completely Automated

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.
