AN FRANCISCO — Google will announce its entry Tuesday into the small but growing business of “smart grid,” digital technologies that seek to both keep the electrical system on an even keel and reduce electrical energy consumption.
Google is one of a number of companies devising ways to control the demand for electric power as an alternative to building more power plants. The company has developed a free Web service called PowerMeter that consumers can use to track energy use in their house or business as it is consumed.
Google is counting on others to build devices to feed data into PowerMeter technology. While it hopes to begin introducing the service in the next few months, it has not yet lined up hardware manufacturers.
“We can’t build this product all by ourselves,” said Kirsten Olsen Cahill, a program manager at Google.org, the company’s corporate philanthropy arm. “We depend on a whole ecosystem of utilities, device makers and policies that would allow consumers to have detailed access to their home energy use and make smarter energy decisions.”
“Smart grid” is the new buzz phrase in the electric business, encompassing a variety of approaches that involve more communication between utility operators and components of the grid, including transformers, power lines, customer meters and even home appliances like dishwashers.
“They’ve been putting a chip in your dishwasher for a long time that would allow you to run it any time you want,” said Rick Sergel, chief executive of the North American Electric Reliability Corporation, an industry group that sets operating standards for the grid.
If the utility could “talk” to the dishwasher, it might tell the machine to run at 2 a.m. and not 2 p.m., or it might tell the homeowner how much money would be saved by running the dishwasher at a different hour.
