PEAK-LOAD PRICING AT FLORIDA POWER AND LIGHT Florida Power and Light (FPL) faces demands during both peak-load and off-peak- load times. FPL must determine the price per kilowatt hour (kwh) to charge during both peak and off-peak periods. The daily demand for power during each period (in kwh) is related to price as follows: Dp=60-0,5Pp+0,1Po Do=40-Po+0,1Pp Here, Dp and Pp are demand and price during peak times, whereas Do and Po are demand and price during off-peak times.It costs FPL $10 per day to maintain 1 kwh of capacity. The company wants to determine a pricing strategy and capacity level that maximize its daily profit.
