The smart grid is the evolution of our current electrical grid, using new technology to optimize the conservation and delivery of power. All told, the smart grid promises to increase the efficiency of today’s system by around 9% by 2030, saving more than 400 billion kilowatt-hours each year. That’s huge. That means we could save $42 billion in year 1 and as we keep saving energy, its value each year only increases.

The "grid" refers to our nation's electric power infrastructure. Smart grid is the application of information technology, tools and techniques that can make the grid run more efficiently. The current electric grid is highly inefficient and very much in need of modernization.

Smart meters run on two frequencies. The frequency communicating to the electric meter is 900 MHz (megahertz). If the premise also has a gas meter, the frequency from the electric meter to the gas meter is 2.4 GHz (gigahertz).

The electric meter frequency is similar to a cell phone and the gas meter frequency is similar to a computer router. Neither device will interfere with any wireless devices in the home and it is highly unlikely that the relatively weak fields produced the meter would interfere with the operation of a medical device.

Utilities are confident in the performance of their vendors and the equipment they are deploying as part of their grid modernization efforts. The meter make / model utilities selected undergo a variety of rigorous tests before they are approved for use in the field. The standardized tests are used to measure accuracy during various load and weather conditions; the tests are industry accepted and approved by the American National Standards Institute (ANSI).

Additionally, utilities have implemented an enhanced testing procedure where they test a percentage of all meters they receive from the vendor prior to installing them at a customer’s home or business. Utilities also continue to monitor meter accuracy after installation by conducting routine sample and/or periodic testing.

Certainly, utilities understand that with any vendor or equipment, problems can occur after installation, so customers are encouraged to contact their utility if there are ever any questions about the accuracy of the meter or the bill.
