Calculate the cost savings in electric utility bills for an industrial customer serviced by the OG&E RTP

Question:

Calculate the cost savings in electric utility bills for an industrial customer serviced by the OG&E RTP rate used in Example 2.8 if the excess electrical load experienced during the curtailment hours (between 3 p.m. and 8 p.m.) is shifted uniformly to the next 4 hours (between 8 p.m. and midnight). With this load-shifting measure, the demand during the curtailment hours would be 500 kW and the total daily energy use for typical days would remain the same as shown in Table 2.18. image text in transcribed

Example 2.8

Calculate the utility bills for an industrial customer serviced by OG&E under two rates:

i. Conventional rate with the following charges:

Customer charge: $150.00 Energy charge: $0.0264/kWh Demand charge: $13.1/kW ii. RTP rate structure with the hourly prices given in Table 2.15 . In addition, a customer charge (referred to as an administrative charge) of $300 is incurred monthly by the customer under the RTP rate. image text in transcribed

The hourly energy use and the contracted CBL profiles (for the RTP rate) are summarized in Table 2.16 for typical week and weekend days (data provided by Mont and Turner, 1999).

Assume that the month has 21 weekdays (including two curtailment days) and 9 weekend days. In the utility bill calculations, do not account for any other charges such as taxes and credits. image text in transcribed
