if the grid is out. And with enough storage, they can disconnect from the grid indefinitely a development utilities fear.
A number of states have net metering, programs in which utilities purchase the excess electricity from solar panels that fed into the grid.
In combination with net metering, behind-the-meter storage creates the opportunity for customers to buy power from the grid
when prices are low and then sell stored energy from batteries when prices are high.
But electric cars create challenges for grid operators. Because they draw so much current during charging, there is the potential to overload circuits that serve neighborhoods.
EVS can help flatten the typical load curve of the grid and draw power at off-peak hours at night.
Since EVS are pulling power off the grid they can also offset excess power production from wind in particular,
Close on the horizon is so-called vehicle to grid (V2g) technology. Standards will finally make it possible to use the EV battery in two-way operation with utilities.

or have excess power, they push power back and forth into the EVSBATTERIES. Owners could be paid for these services.
grid operators struggle to meet the demand. Cutting power during those peak hours gives them more capacity to avoid brownouts.

At Tesla price, utility-scale batteries have the potential to perform better than 2 cents per kilowatt hour where it counts the most:
and if deployed at the grid level, they could actually lower electric bills. Even modeling batteries $100 more than the Tesla, the Texas analysts concluded that storage arrayed across the grid should cause a typical consumer electric bill to fall slightlyrom $180 per month to $179. 66.
That not a remarkable number if one is looking for savings, but it a remarkable number if one expects new capital expenditures on batteries to increase electricity bills. onsidering both the impact on electricity bills and improved reliability of grid-integrated storage,
total customer benefits would significantly exceed costs, the analysts, from The Brattle Group, found. Here why, according to their study:
By deploying batteries along the grid where peak loads are greatest, they can also defer investments in transmission
