Burkina Faso - Reinforcement of Electrical Infrastructure and on Rural Electrification (PRIELER)
The objective of this project was the elaboration of draft studies that deliver sufficient justification to implement the following works:
- Restructuring and extension of the electrical networks of Ouagadougou
- Construction of the 132 kV interconnection line Zano - Koupèla
Design studies, preliminary cost estimates, time schedules, detailed design, and tender dossiers were prepared to determine all requirements for an efficient implementation of the two projects.
A feasibility study was carried out for the interconnection line Zano - Koupèla resulting in the detailed design for the line, including line route study, environmental and social impact assessment (ESIA), and the choice of the substation locations.

Mongolia - Thermal Power Plant #4, Ulaanbaatar (Consulting Services for Modernization and Rehabilitation)
The project encompasses the modernisation and rehabilitation of the Russian design coal-fired Thermal Power Plant # 4 in Ulaanbaatar, which is the largest power plant in Mongolia, supplying electricity and heat to more than one third of the Mongolian population, i.e. approx. 1.1 million people. It generates more than 70% of the electricity for the central energy system. The plant consists of eight coal-fired boilers of 480 t/h that feed six turbines (1 x 80 and 5 x 100 MW). Steam is extracted for district heating and industrial use. The plant runs on middle-grade lignite from the Bangannur and Shivee-Ovoo mines. Project measures should achieve an increase of available capacity by 11.7 MW, a decrease of specific coal consumption and a reduction of the CO2 emissions.
intec's services
- Finalisation of scope and basic design of the project measures
- Preparation and issuance of tender documents/assistance with tender (bid evaluation, contract negotiations) for 3 lots: cooling water cleaning system with filtration, variable speed drives for two boiler feed water pumps and reverse osmosis water treatment plant
