Zambezi agency seeks flow meters for 1,350-MW Kariba plants

The Zambezi River Authority (ZRA) seeks bids for flow metering equipment at the 750-MW Kariba South and 600-MW Kariba North hydroelectric projects on the border between Zimbabwe and Zambia. Bids are due May 30.

One of the functions of the bi-state ZRA is to allocate water to the Zimbabwe power utility for Kariba South (HNN 5/1/08) , which ZRA said has been upgraded to 750 MW from 620 MW, and to the Zambia power utility for Kariba North, which ZRA said is being upgraded to add 120 MW. (HNN 2/27/08)

Monitoring of water usage is achieved by flow meters at the power stations, which have experienced functional problems rendering them unsatisfactory, ZRA said.

The overall objective of the contract is to install an up-to-date turbine flow measuring system to enable ZRA to monitor water usage and to bill the power utilities for water used in power generation. Kariba South has ten turbines, while Kariba North has four.

The contractor is to replace existing equipment and to extend remote transmission of flow data to ZRA headquarters in offices in Lusaka, and in Harare and Kariba in Zimbabwe. It also is to provide training for system operation and maintenance.
