Description :
ENEO is a company in charge of the production, distribution and sale of electrical energy in the Republic of Cameroon under the Concession and Licensing Agreements dated July 18, 2001 and subsequent amendments.

ENEO Cameroon Generation and Distribution utility set up a Technical Design Office operating mainly in the sector of studies of distribution network issues.
The creation of the Technical Design Office was part of ENEO Top Management will to:
• Give a new direction to projects realization with roles separation in the triptych Studies-Procurement-Construction for better visibility, transparency and governance;
• Create a friendly technical environment for incubation of young Engineers on technical professions related to Distribution;
• Reappropriate and internalize the technical professions of Distribution;
• Enable a better issues analysis for a better preparation of the Company's investment programs.

As the volume of investments increased, ENEO decided to appropriate the services of the Technical Design Offices operating in the distribution network studies segment, to assist its B.E.T in the studies of issues relating to its missions.
Description of the Actual Services Provided The service consisted in carrying out design studies concerning the construction of 48km of MV line (30kV) in Almelec 148mm² between the cities of Mbui and Makondo and between Pouma and Messondo.

The studies included for each section:
• Topographical studies : realization of land surveys and details collect (planimetry, altimetry, etc ...) in cases where Eneo does not have them for structures implementation ;
• Geotechnical studies;
• Electrical studies of MV/MV, MV/LV substations and MV parts of Source substations;
• The sizing of the concrete structures of the MV/MV, MV/LV substations and the MV parts of the Source substations;
• Design studies of HV lines using CAMELIA software (Mechanical calculations of conductors; Definitions and choice of media types; Media Calculations; Profile skinning; Picket books; calculations of the Foundations; Tables of Arrows and Conductor Installation Tensions)
