Smart Automation Automated metering- and customer processes

Customer information (power consumption over a time axis, actual power consumption) Automated change of tariff model (Customers choose their tariff model via Internet) Automated disconnection (or limitation of maximum power) of non paying customers Load management

Additional needed Smart Meter functionality Communication platform into the households (integration of gas- water- and heat meters, integration of power generating devices) Measuring functionality for grid parameters (voltage monitoring, voltage dips/outages, symmetry….)

Automated fault monitoring and diagnosis for the MV and LV grid

Integration of short circuit detectors Integration of ground fault detectors Transformer monitoring Feeder supervision

Reduction of grid losses / optimized grid planning and refurbishment

Continuous optimization of grid configuration based on actual load data Improved voltage symmetry Improved dimensioning of infrastructure

Increased application of decentralized power generation devices in households

Grid stability and power quality close to the customers has to be granted

Automatic re-configurating MV grids Introduction of new switching devices Introduction of reclosers

Smart Metering

Changes in two separated business segments (Meteringand Grid Operation) will happen:

- Can a benefit be gained out of synergy effects?

- How can an effective and a future proof strategy be developed, to align regulator requirements and the economic success of the company?

Smart metering:Reference example 1

Reference project for Energie AG Oberösterreich, Austria: The most important reasons for the implementation of an AMIS system are

Automated metering processes (meter reading,blocking of customer installations, billing,prepayment services, etc.)

Significant improvement of customer processes Implementation of various tariffs Quality improvement of consumption data due to

monthly meter reading Replacement of ripple control Recording of customer supply Automation of the transformer stations Support of Energie AG’s energy efficiency program


Smart metering:Reference example 2

High volume meter data managementfor gas and electricity

Time-of-use-based billing Residential load management Exception reporting and integration of

field workforce Automated commissioning of each

meter installation Detailed reporting for retail and

distribution applications Web-based energy Information portal Integrated wireless in-home display Fully managed smart service
