+//Given data
+//(i)A private diesel generating plant
+MD=900;// kW
+F_l=30;// Load factor in %
+Cc=90*10^5;// Capital cost in rupees
+Cf=800;// Fuel cost in Rs./ton
+Fc=0.3;//Fuel consumption in kg/kWh-generated
+Mc=2.5;// Cost of maintainence in paise/kWh-generated
+Oc=0.3;// Cost of lubricating oil,water,store,etc in paise/kWh-generated
+W=180000;// Wages in Rs./year 
+ID_1=10;//Interest and decpreciation in % per year
+//(ii)Public supply
+MD_pub=1500;// Maximum demand per year in Rs./kW
+Mc_pub=80;// paise/kWh

+//Calculation
+//(i)Private plant
+ID=ID_1*Cc;//Interest and decpreciation in rupees
+Nu=MD*(F_l/100)*8760;//Number of units required per year in kWh/year
+Fr=(F_l/100)*(Nu);// Fuel required in kg/year
+CF=Fr*(Mc_pub/100);// Fuel cost in Rs./year
+Cmo=((0.3+2.5)/100)*Nu;//Cost of maintainence,oil and water in Rs./year
+Tc=ID+CF+Cmo+W;// Total cost of running the plant per year in rupees
+Ec_1=(Tc/Nu);//The energy cost in Rs./kWh
+//(ii)Public supply
+Tc=(MD_pub*MD)+((Mc_pub/100)*Nu);// Total cost in Rs./year
+Ec_2=Tc/Nu;// Energy cost in Rs./kWh
