In a circular, the electricity firm said that it will be carrying out routine maintenance of the IT Prepaid System.

"The exercise will be conducted from Tuesday, 3 July 2018 at 10 pm to Wednesday, 4 July 2018 at 10 am. During this period, all PrePaid services which include buying tokens through PayBill 888880 will not be available.

"Other prepaid tokens buying outlets such as our banking halls and vendor outlets will also be affected," the statement read in part.

Kenya Power went ahead to advise customers using prepaid to buy tokens in advance.

However, those using the Postpaid will not be affected during this period.
