Question 9.8: Calculate the utility bill for the facility considered in Ex......
Calculate the utility bill for the facility considered in Example 9.7 taking into account both a fuel cost adjustment of 0.015/kWh and a sales tax of 7%.
The fuel cost adjustment should be applied to the energy use, while the sales tax should be applied to the total cost. Thus, the monthly bill for the industrial facility considered in Example 9.2 becomes
(a) Customer charge=\$450.00
(b) Demand charge=490 \ kW*\$20/kW=\$9800.00
(c) Energy charge=50,000 \ kWh*[\$0.03/kWh+\$0.015/kW]=\$2,250.00
Total monthly charges (befor saies tax) =(a)+(b)+(c)=\$12,500.00
Total monthly charges (after sales tax)=\$12,500.00*1.07=\$13,375.00
The cumulative effect of both fuel cost adjustment and sales tax increased the utility bill for the month by [\$13,375 − \$11,750 = \$1,625].
