Kenya power is implementing a ksh 13 billion underground power network project to improve the quality of electricity supply in Nairobi. The project is expected to reinforce the Nairobi city power supply system by providing alternative supply to existing substations.
This will exist flexibility of the existing system and scale down system losses riding on extension of the transmission line into the city. The project involves establishment of a new 220/66kv substation at the city Centre and construction of 16.5kilometers of 220kv underground cable from Embakasi substation to the proposed city Centre substation at a cost of ah 10.56 billion.
Currently 22 kilometers of 66kv transmission lines is complete while installation work on Liking road substation is finalized and see commissioning test is ongoing. ‘The underground cabling technology is more aesthetic compared to overhead lines and less expensive in terms of land acquisition challenge
Kenya power’s customer base has been growing tremendously over the years calling for investment in the network to ensure adequate power supply. Since June 2013 to date the number of customers has increased from 2.3 million customer to 6million. Meanwhile Kenya power will focus on four main areas mainly infrastructure development, network management, loss reduction and customer centricity in its strive to provide quality electricity.
Underground cabling is one of the ways the company is enhancing the capacity of the power distribution network. Other undertakings geared towards provision of quality electricity include refurbishment of existing substations to enhance their efficiency, construction of additional substations and associated lines and replacement of damaged poles among others.
The underground cabling project is funded by a twenty year concessional loan from China Exim bank and is expected to be completed by the end of July 2017.
The project is being implemented by TBEA co limited as the main contractor and Voacom limited,H.K builders and AKS as the local sub-contractors.
