Here is a rundown on three smart-grid demonstration projects worth noting.

There's one in which IBM, Honda and PG&E are testing whether a Honda Fit and the power grid can exchange data about the Fit's battery and conditions on the grid.

A pilot project in Farmingdale, N.Y., on Long Island, will look at whether consumers, when supplied with dynamic information about energy pricing, will respond by changing their behavior.

And in one Swedish town, a project is examining how the grid responds to intermittent connections such as electric vehicles and how it handles energy input from a series of lithium-ion batteries that ABB installed.

The bond is a link to EPRI's latest updates on smart-grid project around the world.
