Smart Metering

Market Overview and Challenges

Market Overview:

400Mu Smart e-meters to be deployed by

2015 ($2B SAM)

Deployment mainly driven by regulations

and mandates

75% are 1-phase e-meters

Challenges for Smart Meters & MCUs:

Cost effective:

- Meter in a chip

- Reduced Bill of Material

- Reduced calibration time at end of manufacturing line

Security: With an increased number of connected meters, any entry point to the

Grid need to be highly secured and protected against -

- Fraud: Need to guarantee billing information integrity

- Privacy: Power consumption data reflects users activity and can generate added value services

- Hacking: Smart Grid illegal access could result in a black out

Accuracy:

- Meet increased demands for accuracy while deceasing the power consumption of the meter
