Pilot Project Approach

Establish technical solutions for roll-out

Quantify the costs and benefits

4500 smart meters to be deployed

Nanyang Technological University to be the focal i t h th f ll it f li ti d l tipoint, where the full suite of applications and solutions

will be tested

Key Phases of the IES Pilot

Phase 1 – develop backend systems and infrastructure

Commenced in October 2010

2012Expected to be completed by mid 2012

Phase 2 – evaluate customer applications which ride on advanced metering infrastructure

Expected to commence in Q1 2012 and completed p pby mid 2013

Design Consideration

Design with the end in mind

Ability to integrate new technologies in future

Leverage industry-adopted standardsLeverage industry adopted standards

Data live in one place

Utilise standard/best-fit functionality and avoid customisations

Customisations developed outside the core system

Smart Meter – Open and Modular
