What is Demand Response?
• Management of electrical consumption• Active alleviation of grid stress• Load Shedding during peak demand periods

The Shocking Truth!
• It is estimated that a 5% lowering of demand would result in a 50% price reduction during the peak hours of the California electricity crisis in 2000/2001.
• If demand continues to grow unabated, to meet future demand will require 1,300 new power plants supplying 400 GW by 2020.
• It’s not just big corporations driving up demand… It’s you too!
