Smart Metering - the Current
Situation in Slovenia

What are the drivers for meter change?
Requirements for energy saving
A goal without feedback is useless.
Requirements for energy efficiency
To use electricity efficient primarily means to use it at the right time!
Lord Kelvin: “If you can not measure it, you can not improve it!”
Requirements for a greater proportion of energy from renewable sources
Integration of distributed energy resources also into the low voltage grid!
New technologies, for examples:
• electric cars.
(Quater)hourly-based time-stamped measurements are needed!
Power flow tracing and power quality monitoring at the low voltage grid will be
necessary!
Implementation of Demand Side Management / Demand Response is a must!
At least, billing on the basis of actual consumption shall be performed frequently
enough.

Regulatory requirements for the deployment of advanced metering
• DIRECTIVE 2009/72/EC concerning common rules for the internal market in
electricity:
Where an economic assessment of the long-term costs and benefits has been made,
at least 80% of those consumers who have been assessed positively, have to be
equipped with intelligent metering systems for electricity by 2020.

Distribution System OperatorsDSO is responsible for metering.
• 11.500 industrial customers (P > 41 kW):
• All have already been equipped with AMR meters.
• Legislation binds DSOs to collect daily load profiles.
• 900.000 residential and small bussines customers:
• 80 % Ferraris meters, 6 % AMI and 14% other electronic meters (AMR,...).
• Legislation binds DSOs to do meter reading just once a year.

Functional requirements1. System-wide synchronized clock =>
synchronized readings and load
profiles. Accurate tariffs.
2. Remote meter reading and
management.
3. Different options for informing users
about their consumption, tariffs, etc.
(WEB postals, IHDs,...).
4. Remote user
disconnection/reconnection and power
limitation.
5. Time-of-use tariffs, dynamic tarrifs.
6. Multi-utility infrastructure (gas, heat
and water meters).
7. Measurements of losses. Fraud and
theft detection.
8. Power quality monitoring (blackouts,
brownouts logging,...).

Some highlights regarding the technology
• Communication technology:
• Smart meters to data concentrator: the combination of PLC and
GPRS will be used (95% PLC, 5% GPRS)
• Data concentrators to MDMS: GPRS or other networks – like
WiMAX, Ethernet, etc. – od course, if available in TS.
• Performance requirements call for an appropriate quality of services for
the mobile operators networks and for an appropriate power quality on
low voltage grid (PLC).
• Cyber security, data safety, data handling and data protection must be
considered very carefully.
• Equipment interoperability between at least two vendors is required !
• Life expectancy of the system sholud be at least 15 years.

AMI pilot projects
Various pilot projects have been carried out for several years. The biggest, for
example, are:
• Domžale region (Elektro Ljubljana): 17.000 MP, 370 TS
• Žiri region (Elektro Ljubljana): 6.000 MP, 246 TS
• Some highlights of the projects include:
• monthly billing on the basis of actual consumption,
•15-minute load profiles for all customers,
• customers can track their consumption with a WEB portal,
• measurements of losses - fraud and theft detection,
• multi-utility (gas metering),
• performance test were carried out (PLC and GPRS communications).
All DSOs have already operational MDM systems.

Smart Meters Rollouts
Elektro Gorenjska is preparing for a full scale rollout (80.000 metering points).
• Deployment of the system will take 5 years.
• Equipment interoperability between two vendors is required.
• Iskraemeco an Landis+Gyr were contracted to deploy the system.
• The project is in the Site Acceptance Test phase,
• interoperability tests are also performed.
Other DSOs should follow since there is not much time left till 2020!

• The total investment costs, evenly distributed over perriod of 5
years, were assessed at 207 million €.
• Global costs per metering point: 230 €/MP
• Cost benefit analysis shows that the investment into the AMI system
is justified:
