A typical residential rate schedule might be the following: 5 cents per kilowatthour for the first 35 kwhr, 4 cents per kilowatthour for the second 35 kwhr, 21 cents per kilowatthour for the next 130 kwhr, 2 cents per kilowatthour for all energy over 200 kwhr. heater is installed all energy over 200 kwhr shall be billed at 1.3 cents per kilowatthour. Where an electric water EXAMPLE 11. Using the foregoing rate schedule, calculate the cost of service for electric energy if the difference between two successive monthly meter readings is 224 kwhr. Solution Step 1: Step 2: Step 3: Step 4: 35 X 0.05 = $1.75 35 X 0.04 = 1.40 130 X 0.025 = 3.25 24 X 0.02 = 0.48 Total cost = $6.88 Rate schedules for industrial power and light service, generally three- phase alternating current, vary somewhat on the basis of connected load, maximum demand, and energy consumption. In addition to the basic charge for energy (kilowatthours) there are at least three other items of cost, representing property investment and operating expense; that must be included in the bill for service. The latter come under the headings of (1) maximum load and load factor,' (2) adjustment for power factor,' and (3) adjustment for the cost of powerhouse fuel. One such schedule for power and light service, available to customers having a billing maximum load of 25 kw or more, is the following:

EXAMPLE 11. Using the foregoing rate schedule, calculate the cost of
service for electric energy if the difference between two successive monthly
meter readings is 224 kwhr.
Solution
Step 1:
Step 2:
Step 3:
Step 4:
35 X 0.05 = $1.75
35 X 0.04 =
1.40
130 X 0.025 = 3.25
24 X 0.02 =
0.48
Total cost = $6.88
Rate schedules for industrial power and light service, generally three-
phase alternating current, vary somewhat on the basis of connected load,
maximum demand, and energy consumption. In addition to the basic
charge for energy (kilowatthours) there are at least three other items of
cost, representing property investment and operating expense; that must
be included in the bill for service. The latter come under the headings of
(1) maximum load and load factor,' (2) adjustment for power factor,' and
(3) adjustment for the cost of powerhouse fuel.
One such schedule for power and light service, available to customers
having a billing maximum load of 25 kw or more, is the following:
