Focus on Demand Response
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

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
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

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
