What is Power Quality? And how does it save money?
Q. What is "power quality"? And how does it save
money?
A. Your electric utility company or generator system
is tasked with supplying your facility with a steady
source of electrical power: a predictable, stable frequency;
a dependable, steady source of maximum current.
Any deviation from these three targets, at your supply point
or inside your facility, is a deviation from
the ideal, and is referred to as a "power quality"
problem. Of course, the presence of each of these three
factors at your supply and inside all points of your electrical
system is considered perfect power quality.
Fact: No facility has perfect power quality. In fact, within
today's increasingly complex electrical systems,
power quality is an often overlooked and costly element.
There is a widely held myth that poor power quality
has no cost, so long as there are no obvious, clearly seen
manifestations, such as tripping breakers, burning
of equipment or electronics, or erratic production operations.
In fact, the same variations from perfection
of voltage, frequency, and current supply that cause these
problems when present in sufficient magnitude
also cost money when at smaller, less obvious values, even
if there are no overt "problems." Electronic
and motor loads are regularly damaged and affected by poor
power quality, and create the greatest costs.
Unwanted variations in voltage or frequency cause cumulative
wear in both types of loads. A weak current
source starves these loads of power and creates over-hot
operation, which leads to premature failure.
Motors are silent witnesses to the cumulative effect of
poor power quality. Because of their long operating
lifetimes, motors are usually just replaced or repaired
as they fail, and the cause of the failure is often not
diagnosed.
Poor power quality issues can cut motor lifetimes in half.

Project Design
Q. What is a "Project Design," and what does it do for me?
A. Correcting the power quality issues in a specific facility is not as easy as changing
light bulbs or replacing a few motors; either of these requires only very simple information that can be found
on equipment nameplate. And, that's why the companies that sell these products can perform the initial design
work at no charge to a customer. It's really easy to do. And, the lights and motors recommended will be selected
from a number of stock, off-the-shelf products maintained in inventory by the supplier. The only purpose of the
initial "design" work is to permit the vendor to know which models and what quantities of these products will be
needed in that job.
Sadly, our life is not that simple. First, we do not have "off-the-shelf" products; everything we specify
into a job is custom-made for not only that job, but also for the precise piece of equipment or exact point
in the electrical system it is intended to be placed.
Secondly, we cannot have a "standard" approach to our work; every single facility is sufficiently different
to make this cookie-cutter approach impossible for us. In fact, we cannot even successfully do our job based
upon examining even detailed plans of a facility's electrical system. Our design work must be based upon
observed and measured data from, literally, every single electrical load and circuit in your entire facility.
All of your equipment and each of your electrical circuits forms a highly interactive whole, that ultimately
connects to your building's electricity meter. It is only by thoughtful and detailed evaluation of each separate
element in this overall system that we can responsibly arrive at the most cost-effective set of treatment
recommendations for your facility.
What degree of savings can I see?
Q. What degree of billing savings can I really expect?
A. Don't you really mean, "How good of a return will I see if I invest in your approach?"
What if we could reduce your electricity bill by 80%? Wouldn't that be great? But, what if it took 25 years
for this savings amount to reimburse you for the cost of our work? Would it still be a great deal?
No way.
What if we could only reduce your electricity bill by 3%...but the savings paid for the cost of the work in
six months? Would that be a good deal? Of course.
Depending upon the conditions of your electrical system, the mix of equipment, lighting, and air conditioning
you have, your normal hours of operation, and a variety of power quality issues, we could see project design
results in your facility of from 5% to 35% billing savings, with payback periods of from 10 months to over
100 months. Typically, the range is narrower, from 10% to 20% savings, and with payback around 36 months.
