Smart grids/ What is EnerTracker?

Smart Grid

Smart Grid: “… a power system that can incorporate millions of sensors all connected through an advanced communication and data acquisition system. This system will provide real-time analysis by a distributed computing system that will enable predictive rather than reactive responses to blink-of-the-eye disruptions.” (The Electric Power Research Institute - EPRI)

What is EnerTracker?

EnerTracker tracks the energy consumptions of individual home appliances using a single sensor. The sensor clamps on the plastic conduit going to the electrical panel of a house. The results are stored in internet. Users can monitor the energy uses of their appliances and houses with any internet accessible devices.

Uniqueness
• Monitor individual home appliances using a single sensor

• The sensor can be installed easily by customers

The sensor

•A device clamped on to the conduit of power panel;
•Can figure out the currents in the conductors enclosed in the conduit
The sensor
The receiver
•A device that connects to a home internet router
•Receive the data from sensor and transmit it to internet
The server and display
•A data server at a remote location that can process the data and determine the energy use of major home appliances
•Any internet accessible device can see the results

Customers only need to install the sensor and receiver

• A breakdown of power bill per home appliances
• The power cost associated with each use of a home appliance
• The energy use performance of a specific appliance in comparison with
similar types owned by others

What do a user get?

• A breakdown of power bill per home appliances
• The power cost associated with each use of a home appliance

The energy use performance of a specific appliance in comparison with similar types owned by others

The potential energy bill savings

if an appliance is used differently

Status monitoring (garage door

close, oven turned off, …)
