Smart Metering_ added value for customers?

• Extension of the “Broadband power line“ – testing relibility / availability / data transfer

• Project “Narrow band power line” – Meters using Meter&More protocol.

PLC GPRS• Technologically insufficient• Interoperability (the importance of IT)• Very high costs CAPEX, OPEX

• First Pilot Project → To test usable functionalities from the perspective of distributor

I. Phase – Display consumption data and price→ short term added value!

II. Phase – „Virtual super cheap fare, super expensive ”→ Low motivating customers to move their consumption even at a high price difference!

• Pilot project focused on the end user Smart meters gives them added value?

→ use PLC technology for low and medium voltage.

→ to test the possibility to change the currently used ripple control HDO

→ communication module implantable in any meter (interoperability)

• Pilot project „Broadband power line“

How it

works?

Operates by adding a modulated carrier signal to the wiring system. For this

reason utility companies uses special coupling devices to connect radio

transmitters to the power lines.
