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.

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 of “Audit Sections” thereby reducing the Area of Focus.

Energy Audit Extract Triggered
Existing Process Flow
Updated Process Flow
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 of 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.
