45. For customers generating their own solar power, ZG&E charges them $3 per month per kilowatt (kWh) for excess electricity they export to the grid. Ready Edison charges customers a flat rate of $20 per month and credits them $0.06 per kWh for excess electricity they export to the grid. Determine the monthly bills for customers of both companies for each of the following:(A) Customer owns a 3-kW system and exports 120 kWh monthly to the grid.(B) Customer owns a 5-kW system and export 300 kWh monthly to the grid.

Respuesta :

(A) The customer that owns a 3-kW system exports 120 kWh monthly to the grid will have the following bills for both companies:

For ZG&E that collects $3 per kWh on a monthly basis, the monthly bill will be

[tex]120kWh\times\frac{\$3}{1kWh}=\$360[/tex]

For Ready Edison that collects $0.06 per kWh exported energy monthly, the computation of bill will be

[tex]\$20+(120kWh\times\frac{\$0.06}{1kWh})=\$27.2[/tex]

(B) The customer that owns a 5-kW system exports 300 kWh monthly to the grid will have the following bills for both companies:

For ZG&E that collects $3 per kWh on a monthly basis, the monthly bill will be

[tex]300kWh\times\frac{\$3}{1kWh}=\$900[/tex]

For Ready Edison that collects $0.06 per kWh exported energy monthly, the computation of bill will be

[tex]\$20+(300kWh\times\frac{\$0.06}{1kWh})=\$38[/tex]
