Network planning is a complex process encompassing collection and analysis of a large number of technical and non-technical data. The aim being to ensure reliable, stable power systems in the pre-sent and/or in the future.


intec offers professional methods for analysis and calculation of transmission networks for all voltage levels (from simple point-to-point interconnection to extra-high-voltage transmission networks), medium/low voltage distribution networks of any size (from micro grids to large interconnected power systems). Our experts provide power system modelling and analyses, grid integration studies as well as grid stability analyses using various modern and internationally-recognised software such as Siemens PSS®E and SINCAL, DigSILENT, PowerFactory, NEPLAN, WASP, ArcGIS etc.


intec’s team of specialists is also able to perform development plans for distribution and transmis-sion networks. This includes grid integration studies of conventional and renewable power plants, and subsequently to establish grid codes and other documents defining technical requirements and oper-ation rules for all energy market participants.


In accordance with the best engineering practices, we can provide our clients at the operation level of power systems with information or complete studies a day or several days ahead of operation. These studies include forecast modelling and analyses, net transfer capacity, generation adequacy analyses, protection coordination studies, solutions for high penetration of variable renewable sources, power quality, power system stability, congestions or short circuit currents to name but a few.


In the framework of all these activities, intec has the knowhow and experience to organise adequate appropriate training programmes on a diverse range of topics.
