What is Demand Response?

• Management of electrical consumption• Active alleviation of grid stress• Load Shedding during peak demand periods

Controlled Load

Shedding / Balancing

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!

Communication enables efficient energy use

EnviroGrid’s swarm logic ensures that loads:


IP enabling edge devices leads to energy efficiency


Swarm methods for Demand Response

• Self configuring mesh network uses swarm logic to load balance all connected loads with minimal to no impact to occupant comfort

Swarm Optimized Networks

• No need to worry about thermostat setbacks, swarm logic is adaptive and self configuring


Real-Time Control and Reporting down to the level of each load is a “must have” to confirm activity
