Who will take the readings from the meter?

It also offers the “Reading Logging” service, which allows each customer to inform us of the readings of his meter, so as to get rid of interim Electricity Bills based on estimates.

Is there a possibility of discrimination and power cutoff only for the customers of GREEN, but not for the customers of PPC?

There cannot be, and there is not, any distinction between different groups of customers, as the Grid is common, irrespective of the electricity supplier of each individual customer.

Where there is a blackout in my area, will I be affected too, given that I am a customer of GREEN?

As the Grid is common, a blackout will affect all consumers in the area, including you, irrespective of their electricity supplier.
