Focus on Demand Response


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)


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


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
