Renewable Energy Management Center

by

T R Ganesh

WHY REMC?

• Ambitious plan by Govt of India for 175 GW RE.

• Recognise that RE is a different ball game• Must run

• Flexi watts, Reserves, Balancing etc

• Forecasting and Scheduling

• Interface with existing SCADA and

security tools

• Interface with existing scheduling suite

• Skill set requirement

Pattern of Renewable Generation in India
