If the units of power consumed is less than or equal to (<=) 75 kW per month, the government
will subsidize at the rate of 17.64 cents per unit for all consumptions equal to or less than
75kW per month and in effect the customer will pay 17.20 cents per unit.
If the units of power consumed are greater than (>) 75 kW per month, the user is not entitled
for government subsidy. All consumptions will be charged at the rate of 34.84 cents per unit.
