GE’s Plans to Help You Manage Your Energy Use

GE Appliances & Lighting created the Home Energy Management (HEM) business, intending to be the first major appliance company to provide a whole-home solution for energy management.

When synchronized with the local utility company’s home smart-meter, coming into popular use, the HEM acts as the “central nervous system” for monitoring resource usage and controlling energy consumption within the home. The HEM, with the ability to collect data on multiple appliances, provides both real-time and long-term trend information on power and resource consumption and solar generation to the homeowners.

GE’s new Home Energy Manager (HEM) monitors all networked appliances which can include the refrigerator, range, dishwasher, washer and dryer, water heater, and will track all other home energy consumption including microwaves and televisions.

One of the primary goals of U.S. smart grid initiatives is to better use the energy production capacity the country already has. Home energy consumption efficiency can increase significantly when homeowners the option to participate in time-of-use pricing programs, which reward homeowners for lowering their consumption during periods of peak energy demand (usually 2-7 PM).

Simply providing consumers with energy consumption information motivates energy savings. A U.S. Department of Energy study showed that providing real-time pricing information to consumers via a smart meter helped reduce electricity costs 10% on average and 15% during peak periods.

“Knowing what is consuming electricity, and how much electricity that appliances are consuming, can be very empowering,” states Dave McCalpin, general manager of the new HEM business. “People will be able to make smarter choices if they have information. The once-a-month electrical bill provides no insight into your usage habits. We intend to change that.”

HEM’s design is targeted to include:

* Demand Response Integration, supporting communication standards Zigbee SEP 1.0, to enable demand response communication between a utility’s home smart meter and appliances on the home network, enabling real-time load shedding of networked appliances;
* Five-Day Weather Forecasts on Internet-enabled installations (communications supporting Ethernet, Wifi, and Zigbee SEP 1.0 standards);
* Electricity Usage Data Monitoring for the whole home for both short and long terms;
* Power Sub Metering for each GE demand response-enabled appliance;
* Solar Generation Monitoring of inverter output, including short- and long-term data where available;
* Water Usage Monitoring via household-wide data monitoring at 1-gallon resolution;
* Smart Thermostat Interface with full-featured seven-day programmable communicating thermostats that accepts demand response temperature offsets.

Whirlpool gets US Grant for Smart Appliances

Whirlpool has announced that it is the recipient of stimulus funds as part of the U.S. Department of Energy’s (DOE) Smart Grid Investment Grant program.

The grant of $19.3 million over a two year period – which Whirlpool will match with its own investments – will help the company accelerate its work to deliver to consumers smart appliances that can connect with the smart grid. For example, the company recently announced that in 2011 it would deliver one million U.S. manufactured smart dryers capable of reacting intelligently to signals from the smart grid by modifying their energy consumption to save consumers money on their home electric bills. In markets where utilities offer variable or time-of-use pricing, these dryers could save a typical consumer $20 to $40 per year, while also benefitting the environment.

“The grants announced today are a great example of public and private partnerships that will create the next generation of energy saving solutions,” said Mike Todman, president, Whirlpool Corporation North America. “Smart appliances combined with time of use pricing offer consumers the greatest ability to save money on energy costs while benefiting the environment.”

In addition, the funds will complement the company’s commitment that by 2015 all of the electronically controlled appliances it produces – everywhere in the world – will be capable of receiving and responding to signals from the smart grid. This commitment is dependent on two important public-private partnerships: the development by the end of 2010 of an open, global standard for transmitting signals to and receiving signals from a home appliance; and appropriate policies that reward consumers, manufacturers and utilities for using and adding these new peak demand reduction capabilities.
