Present technology
• electric meter device which measures the
amount of consumed electric energy
• consumption in Kilowatt hours
• Ferraris-meter most common technology
– Magnetic fields: consumer electricity, consumer
tension
• multirate meters (industry)
• somebody has to read off the electric meter
Smart metering technology
• combine electric metering with two-way-communication systems
• communication systems– displays real use
– transfers meter data to the supplier
• flexible tariffs (peak-load-pricing)
• supports micro generation technology (wind turbines, solar panels)
• different types of payment (prepayment or credit)
• forecast energy demand
Advantages of smart metering
• exact billing (mathematical projection)
• energy savings (3%)
• reading off stops
• flexible tariff changes (tariff or supplier)
• just one needed meter (two locally placed meters)
• metering production & consumption (PV, mini cogeneration units)
Disadvantages of smart metering
• implementation costs (800 million Euro up to two
billion Euro)
• privacy (data privacy, consumer protection)
• inferences on customer behavior (through
permanent recording)
Smart metering in Austria
• About 40.000 already
installed
• Pilot projects
• Technology by Siemens
• Energy providers patient
• Huge competition
• Disadvantages
Smart metering and the Internet
• Software to track energy usage behaviour
• Microsoft Hohm – Google PowerMeter
• Software connected with data from energy
provider
• Currently tracking the energy use, in future
controlling?
Smart grids
• Definition:
„electricity networks that can intelligently
integrate the behaviour and actions of all users
connected to it - generators, consumers and
those that do both – in order to efficiently deliver
sustainable, economic and secure electricity
supplies.” (The SmartGrids Technology Platform. 2006)
Smart grids
Smart grids should not be mixed up with smart metering, it includes much more technologies etc.:
The SmartGrids Technology Platform. 2006. “What is a Smartgrid?”
Advantages
• Environmental benefits
• Renewable energy
• Increased efficiency
• Security and reliability
• Money savings
• Integration of decentralized energy poducers
• Open energy market
• Disadvantages: costs, privacy, technology
Historical development
• Up to now:• grid with centralised power plants
• unidirectional load flow
• limited grid integration for new electricity producers
• top-down operational planning with previous data
• Current trend:• implementation of decentralised power plants
• multidirectional load flow
• grid integration for new electricity producers
• planning with real time information
Historical development

traditional grid vs. smart grid
ABB, 2009 „Auf dem Weg zum intelligenten Stromnetz“
Examples for realisation in Austria
Bundesministerium für Verkehr, Innovation und Technologie, 2009 „Intelligente Energiesysteme für die Zukunft“
•National pioneering projects
•Vöcklabruck: intelligent measurement and information system
•Smart consumer: municipality Großschönau -consumers as key players
•Biosphärenpark Grosses Walsertal: smart distribution grid
•Smart infrastructure in Salzburg
•Murau: energy vision – fail-proof power-supply for the region
•Smart services in Greater Linz
Model region Salzburg – smart infrastructure
• Vision to become the first Austrian model region
concerning smart grids
• Tough challenge to implement a smart infrastructure
(geographic situation)
• Finding solutions of an overlapping cooperation between
the energy sources and the infrastructure components
Steps of development
• Actually the Salzburg AG runs 26 hydroelectric power
plants, two thermal power stations and several
photovoltaic systems and biomass plants
• Creation of a better grid integration for suppliers of
renewable energy
• To guarantee an active customer participation (clarify
how to handle information)
• Finding the best technology solution for the customers
• Advance the implementation of bloc heating works
