1 Smart metering Declan Meally 7 th November 2008 Aachen

2 Smart metering Electricity in Ireland. What is a smart metering. What we are doing in Dundalk. The National Trial Some international aspects

3 Import Dependency 90% +

4 Irish electricity generation

5 Irish Housing Energy Use 26% of Ireland s energy use Energy spend 1.9 Billion p.a. 12Mt CO 2 emitted p.a. Energy saving potential >20%

6 Irish National Electricity Targets 15% electricity generation by wind by % Renewable electricity generation by 2020 mostly wind. Recent study states Irish system could cope with 42% wind generation. 20% improvement in national energy efficiency. 30% for public sector.

7 How? Interconnection. Combined cycle gas turbine generation. CHP Smart metering. Government commitment. Electricity supplier commitment 22Bn investment!

8 Why smart metering Two way communication power line carrier GSM GPRS Real time information display Allows time of use pricing Import & export potential allows local generation Switching capability.

9 Basic functions Smart Meters should have the following features: the ability to record and store register and interval data kw and kvar, import and export, also voltage profiles an integral remotely controllable switch the ability to record and flag events such as tamper or loss / restoration of supply Metering data stored in the meter, Compatibility with a remote home display unit

10 System Architecture Concentrator MV/LV SUBSTATION TLC LINK CONTROL CENTRE CLIENT POWER LINE CARRIER Meter Information terminal

11 INBOUND Meter reads Connectivity Tampering Customer FUNCTIONALITY Internal Memory to store information for at least a year Utility OUTBOUND Activate / De-activate Change power entitlement Pre-payment / Tariffs Software updates messages

12 Benefits Timely accurate automated meter reading Elimination of manual meter reading costs Accurate and timely billing No access issue overcome On demand readings Reduction of electricity theft Remote operation of meter eliminates need for access Facilitate micro-generation to be connected to the grid and associated tariff/credits for exported energy. Outage and Power quality monitoring monitoring

13 Dundalk pre trial 200 homes 50 as control group - baseline 3 x 50 test groups

14 Demand Side Management Implementation Data transfer Behavioural study Test of stimuli Energy efficiency impact. Examine potential for Peak vs Total energy saved

15 Advance Metering Infrastructure

16 Behavioural stimuli

17 In home display

18 Energy Management Structured approach. Targets. Provision of good data & information. All benefits the customer to make good decisions. Potential of between 10% & 15% efficiency.

19 National Pilot - Objectives Put in place pilot smart metering infrastructure Establish the best portfolio of smart metering technologies for Ireland Evaluate all the costs and benefits of Smart metering Support Government / CER s objectives around ToU Tariffs, demand management and energy efficiency 25,000 meters installed with first batch of 8000 meters in place during winter /11/2008 Tom O'Callaghan 19

20 Irish National Trial Most international trials focus on technology Advanced metering infrastructure Meter data management. Customer behavioural trial start Nov 08. Trial of behavioural stimuli. Real time billing Time of use tariff trial Technology trial Data transfer Meter infrastructure Renewable micro generation.

21 European picture Sweden: Driving Scandinavian Smart Metering. Government requires electricity meters accurately read monthly by 2009 Norway: Government looking at adopting Swedish model Denmark High Government tax on energy is driving Smart Metering programme and revenue collection Italy: Enel have installed 30 million Smart Meters since 2003 at a rate of 40,000 a day! Worked in collaboration with Echelon USA based manufacturer Programme complete in Italy (ENEL, AEM, ACEA)

22 International outlook A future without meters? Smart appliances. Home area networks. Load management. Who will jump first?
