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. S Several i l items of i f f information on this bill can i hi 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. Remember – Your electric bill could be your friend!
