The cost of electricity is expected to significantly come down after the Mombasa-Nairobi transmission line is completed.

Works on 400kV transmission line, the first in Kenya and East Africa, is expected to be complete in two weeks.

The Sh12.6 billion project began in December 2010 and is composed of 482km of the 400kV line between Mariakani and Isinya, and 220kV portions of double circuit transmission line between Isinya-Athi River- Embakasi.

The project has three substations at Mariakani, Rabai and Embakasi.

The new line begins at the Rabai substation and will connect to Olkaria II Geothermal Power Station through Suswa and Isinya, making transmission of power cheaper and more efficient.

The highestcapacity power line Kenya currently uses has 220kV.

Kenya joins countries such as the UK, which use power lines of similar capacity.
