BASIC PARAMETERS TO BE CONSIDERED FOR THE PROJECT (WHEREVER
APPLICABLE)

GENERAL INFORMATION
The objective of the Tendaho Sugar project is to establish a new sugar plant with a
total design cane crushing capacity of 26,000 tons per day to produce about
600,000- tons/annum of raw sugar and 50 % of raw sugar is to be refined to produce
refined sugar of EEC Grade II specifications. The project site comprises of Tendaho
dam and the proposed sugar factory which is located in the lower portion [delta
region] of the Awash basin and in Afar Regional State of Ethiopia. The dam site is
located 575 km away from Addis Ababa, capital city of Ethiopia, and is connected
through a very well developed highway from Addis Ababa to City of Djubouti.
Semera is the new capital city of the Afar Regional State, which is still under
construction, is located on the Addis Ababa Djubouti highway at a distance of 580
km from Addis Ababa. Logia, Dubti and Asaita are other towns in the nearby area.
The detailed picture of Ethiopia showing Tendaho is shown in Figure 1a and the
project area/Site is shown in Figure 1b.

GENERAL SITE DATA
Road approach
Project site is located in the lower Awash valley of the
Afar Administration region and about 600 km North
East to Addis Ababa. Road transport on all weathered
surfaced road almost up to the site is available.
Sea Port
Port of entry for imported goods by marine transport is
Port Djibouti. The transportation from Port Djibouti to
Tendaho site is by Addis Djibouti tarmac highway.
Air Port
Port of entry for air transport is Addis Ababa (about 600
km from project site).

PREVAILING WIND
During the milling season the prevailing winds are approximately South Westerly
from May to October, North-easterly from November to April. The factory building
should be designed for wind speed of 79 km/h.
