The commercial department of the Central Authority was staffed at the top by three ex-CEB men who had been experts in the complex bulk tariff rules laid down in 1926 to secure equity between independent undertakings: a job which no longer existed.

On April 25, 2007, an intended secondary offer for the shares, in pursuance of the IPO's initial success, was abruptly postponed by former Finance Minister Amos Kimunya attributing the move to the prevailing share price being very low and the bulk tariff conflict between Kengen and KPLC.
