Smart metering

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)

Examples for realisation

Smart metering in Austria About 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 metering and the Internet

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 “What is a Smartgrid?”

Smart grids Environmental Stewardship Committee at VTS “Smart Grid”

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 18 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
