According to the US Department of Energy,
approximately 67% of the energy in the form of
electricity is wasted from the point where it is
generated and enters the electrical grid, to the
point where a consumer uses the electricity.

Project Results

Average voltage at meters: 120

121V


Most motor loads, lighting, and appliances operate
at maximum efficiently at 110
-

114 volts.

Excess voltage above this level is typically
dissipated as heat and wasted.

Approximately 70% of homes and buildings
receive more voltage than they need.

“Major decline in

the number of

computer board repairs
in 2008 from the

same time period

in 2007.”


“P&L reports show a decrease of
59%

or a savings of
$
5,406

in maintenance costs over prior year.”


“Supply purchases to repair or replace

parts decreased
significantly, by a reported
42%

or a savings of
$
12,164

from the same period in the previous year.”


“The savings of
$
17,570

appears to be a direct result of
the installation of the MicroPlanet 3 Phase regulator.”
