#batteries: Save Money

Giant batteries,
. . . help renewable energy grow,
. . . in New England.

Grid-scale batteries can serve many functions:
. . . . . . Stabilize the electric frequency at 60 hertz per second,
. . . . . . “peak-shaving,” for one hour, saved our customers close to $200,000,
. . . . . . “firming & smoothing,” soak up excess energy when it’s being produced, and
. . . . . . . . . then push it onto the grid when the generators go silent
. . . . . . Save "Rejected Energy." (See Chart)

Every 4 seconds, computers tell the batteries to store or discharge energy,
. . . ramp at a rate of 1,  2, to 10, megawatts . . . within a single second,
. . . provide the service, at a price that reduces costs for consumers, and
. . . still make a profit.
