Appliances Wipe Out Blackouts
From the article:
- The devices switch off when they detect a power disruption on the electricity grid. Energy officials say the devices could save consumers billions of dollars by reducing the need to build new power stations.
The DOE's Pacific Northwest National Laboratoryis teaming with power companies to determine if home appliances that sense power fluctuations can make the electric grid more resilient and cost-effective. The first test this summer will involve 150 clothes dryers and 50 water heaters that will shut down for two to three minutes during power disruptions caused by demand overloads or severe weather events.
- The long term goal is to integrate the $5 controllers into appliances such as refrigerators, water heaters and air conditioners that together make up about 20 percent of the nation's power load, Pratt said. Building a smarter grid could allow appliances such as TVs, computers and lights to remain on, according to Pratt, and could avert blackouts similar to what happened in the Eastern states in 2003.
