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.

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).
Studio Pietrangeli, whose know-how is based on a solid knowledge of computational and modelling methodologies, has substantial experience in the following specialised fields and disciplines:
- Network studies for transmission and distribution systems
including:
- Load flow analysis with optimised power flow approach
- Short-circuit currents and levels calculations
- Voltage collapse inception studies
- Assessment of transient and dynamic stability of large power networks
- Assessment of inter-area oscillations across very extensive networks
- Energy Demand Forecasting Studies
- Evaluation of the electricity supply-demand balance update
- Generation and transmission master plan updates
- Cost-benefit analysis of alternatives
- Economic and financial analyses purposed to bankability of new projects
- Market and business asset research
- Assessment and identification of institutional and regulatory frameworks
- On-the-job training and knowledge transfer through seminars and specific courses
