High Voltage Lines
The design of transmission lines is one of the services that Studio Pietrangeli has been providing for decades, bringing excellency into engineering in the smartest and most successful way. Passion and commitment of our experts are underpinned by state-of-the-art methodologies and the outstanding Italian tradition in power system disciplines, worldwide recognised.
Batoka Transmission System (Zambia/Zimbabwe)
This remarkable project is amed at integrating the Batoka Gorge HES within the interconnected power system of Zambia and Zimbabwe. The scheme entails application of phase-shifting transformers for addressing the issue of controlling power flows across the cross-border interconnector in a reliable, safe and resilient manner.
High Voltage Interconnector (GABON-CONGO)
This 400kV interconnection line, 350km long, is part of a much larger backbone (about 2000km) from the DR Congo to Equatorial Guinea. It represents one of the priority integration projects planned by the PEAC. It is conceived to wheel large quantities of energy over very long distances promoting renewable sources integration in the regional grid and increasing cross-border electric power trade.
Ruzizi's Transmission System (DRC-Rwanda-Burundi)
This is a very prestigious project which aims at an equitable distribution between the three countries of the hydroelectric resource coming from the Ruzizi waterfall developments. It is at the centre of the implementation strategy of the infrastructures for the regional market in the ECGLC countries.
More than 10 000 km of high voltage lines designed
The engineering services provided by Studio Pietrangeli cover all aspects
of high voltage electrical systems design, feasibility, investigations, environmental and social
impact assessment, detailed design, final design, tender documents, design for construction, works
supervision and technical assistance during procurement.
When designing high voltage lines and, more generally, transmission systems, Studio Pietrangeli's electromechanical engineers carefully select the network nodes to be connected, the voltage level, the reliability of the line route and its interference with protected natural areas and major infrastructures, the power to be transmitted in accordance with the indications set by the national grid code. They pay particular attention to harmonising the equipment of the transmission lines with that already present in the network. Given the key role played by transmission infrastructures in the overall electric system, planning studies are among the core expertise of our activities tailored to the technical and economic evaluation of new assets, renewable resources integration and strategic analysis devoted to system expansion plans.
We would like to point out that Studio Pietrangeli usually collaborates with the most important regional authorities in the energy sector such as : EAPP - Eastern Africa Power Pool, SAPP - Southern Africa Power Pool, PEAC - Central Africa Power Pool, WAPP - Western Africa Power Pool, EGL - Energy Organisation of the ECGLC - Economic Community of the Great Lakes Countries, ZRA - Zambezi River Authority, NELSAP - Nile Equatorial Lakes Subsidiary Action Program, and with national electricity companies such as TANESCO (Tanzania), ZESCO (Zambia), SEEG (Gabon), SNE (Congo), SNEL (DRC), REGIDESO (Burundi), EDCL (Rwanda), KETRACO (Kenya), EEPCO (Ethiopia), ZETDC and ZESA (Zimbabwe), NPA (Sierra Leone), SONABEL (Burkina Faso).
