1. SINTEF Energy Research Experiences and results from Norwegian large scale AMR / RLC project EU Electricity Metering Seminar, Ispra, March 7 -05 Ove S. Grande SINTEF Energy Research Trondheim, Norway

2. SINTEF Energy Research The Nordic Power Market Spot market (Nord Pool) Balancing Market (TSOs) Financial Market (Nord Pool) Bilateral Market Norway Sweden Finland Denmark Germany Russia Capacity shortage Focus on Demand Response

3. SINTEF Energy Research Project motivation and focus Reduction of low prioritized load in peak load periods Reduction of price spikes Improved demand side price elasticity Focus on test and utilization of two way communication infrastructure (Automatic Meter Reading (AMR) + Remote Load Control (RLC)) as basis for Demand Response (Downloadable documentation at www.efflocom.com)

4. SINTEF Energy Research Status hourly metering Norway TWC to all customers >8000 kWh ? 80 000 customers ~60-70 % of the load Presently hourly metering is available from all consumers with yearly consumption > 100 000 kWh

5. SINTEF Energy Research Large scale test project Two way communication to 10 894 residential customers AMR- Hourly metering RLC- available for 50 % of the customers 6 technology vendors involved Terminal R a d i o GSM/GPRS

6. SINTEF Energy Research Main challenges Technology Data quality (referred to market settlement requirements) Standardization of interfaces

7. SINTEF Energy Research Data quality during test period

8. SINTEF Energy Research Power Supplier Network Operator CIS Transmission System Operator CIS MVS FE Customer Meter data Load control Settlement data WH Standard interface EDIEL/EDIFACT Non-standardised interface Settlement data Actors and interfaces Interfaces for information exchange Power Exchange

9. SINTEF Energy Research Incentives for reducing consumption Network tariffs ToU Energy Tariff (= Fixed part + Network losses + Variable Energy part) Energy part only activated in peak hours Peak load months Peak load hours Supplier products Spot price on hourly basis Spot price on hourly basis combined with agreements for remote load control Criteria for load control Spot price criterion Reserves criterion

10. SINTEF Energy Research Response on spot price 70

11. SINTEF Energy Research Test result RLC water heaters at different hours Nordic peak hour

12. SINTEF Energy Research Customer response to price signals

13. SINTEF Energy Research Conclusions Technology improvements are needed. Lower investment costs Quality of data Standardisation of interfaces in the “meter value chain” Registered reduction in consumption as response to price signals was 0,2 – 1,0 kWh/h 0,5 kWh/h response from remote load control of electrical water heaters 50 % participation of Norwegian household customers:  600 MW potential load reduction in peak hour
