Telecommunication need for utilitiesSync of production and usage of energy

This brings high demands for the telecominfrastructure.

1. Future proof > 15 to 20 years.2. High security3. High availability4. Superior indoor coverage5. Interoperability of hardware6. International standards7. Low TCO

Smart grid : (near) real-time communication tocontrol the grid.

Smart meter: secure communication, datacollection and control of energy endpoints.

3. PLC/GPRS Current issuesPLC

Issue Impact Status

Limited and unreliable communication Performance barely meetsprescribed requirements and doesnot meet future requirements

Opportunities for research onperformance improvement

Weak legal position in case of transmissionfailure

High probability of re-visit of sitesper address to repair problems.

European initiatives have beenlaunched to improve EMSregulation for PLC

Network coverage/penetration variable andunpredictable

Relatively high rollout costs andadministrative expenses

Improvement uncertain

High maintenance/management Relatively high management effort Improvement uncertain

GPRS

Issue Impact Status

The maintenance of GPRS as a nationalservice is very uncertain. The required termof 15 years will probably not be met

Early replacement of the entireamount of GPRS modules in thefield

Final decision is not expectedfor 2013

Technical lifespan of crucial components ofGPRS does not meet the requirements

High risk for re-visit within life-spanfor repair/maintenance issues

Improvement uncertain

Communication performance will probablynot be sufficient for increasing bandwithand communicatino needs during lifespan

High risk for re-visit within life-span Performance improvement notpossible (higher bandwidth notpossible)
