THIS MONTH WE’LL wind up our review of practical steps to save on electrical bills with a brief look
at the bills themselves. Electrical bills are not ordinarily thought of as anything other than a necessary
aggravation in the complicated process of producing and delivering drinking water to a customer or
collecting and treating the wastewater from that customer. Surprisingly however, these bills, with a
little effort, can become one of the best tools the water manager has in his toolkit.
As a basis for this review let’s consider this
typical bill which happens to be from Alabama
and was issued by the Alabama Power Company
to a water system.
l items of i f
f information on this bill can
lead to money savings:
• On the left column note the difference of
over 100 kW between Pk kW of 493 and Bill
Demand of 628. This means the system is
paying for 100+ kW it didn’t use. Partly due
to our friend Mr. Ratchet.
• Again on the upper left column, note the
electric meter number 3165211. Be sure the
actual meter installed has this number. If not,
the constant (1) in the
4th column on the left
may be wrong and all
the figures will be also.
• In the figures on the right, note that all the
KWH (110,443) are charged at about 7.5 cents
per KWH. This company has a lower rate of
5.5 cents that is charged at higher kilowatt
hour amounts and it may be possible to take
advantage of this. See last month’s suggestions in this regard.
• Note the item Power Factor of 0.7071 toward
the bottom of the Metering and Usage figures. This is primarily a reflection of the
design and condition of the pumping equipment and the power company penalizes the
customer if it is below 0.90 and this penalty
is the other reason for billed demand being
higher than actual demand. Fortunately, it
can be corrected fairly easily.
• Finally, if you know the output of the pump(s)
at this location, you can get a rough check
of the water meter accuracy by multiplying
output by the quotient of KWH (110,413)
divided Pk kW (493). This quotient is a rough
measure of the hours this station operated
that month and the product is approximately
the water pumped.
