NEW YORK (CNNMoney.com) -- Some 18 million smart meters are set to make their way into American homes as part of the economic stimulus plan focusing on energy efficiency, Energy Department officials said Tuesday.
The meters, which are designed to more effectively communicate with utilities and appliances, and help consumers manage their electricity more efficiently, are being distributed by utilities around the country with partial funding from the federal government that was allocated under the stimulus plan.
The 18 million meters represent roughly 13% of all electricity meters nationwide.
The smart meters are part of a wider government effort to upgrade the nation's aging utility grid. The government announced $3.4 billion in funding Tuesday to help move the country toward a so-called smart grid. Utilities are putting in another $4.7 billion in matching funds.
The money is part of nearly $100 billion in spending and tax cuts the government authorized under the stimulus plan for a variety of energy projects.
Other projects announced Tuesday include modernization of electric substations and transmission centers.
Experts have long said the country needs to update its electricity grid, much of which was built during the early part of last century, if it is to deliver power more efficiently and handle electricity generated from sources such as wind and solar.
