Conflicting interests between stakeholders, the legislation and different transmission technologies turn TL planning into a complex spatial decision problem, however. Therefore, a Spatial Decision Support System (SDSS) which combines Multi-Criteria Decision Analysis (MCDA) techniques with methods provided by Geographic Information Systems (GIS) can support decision-makers in finding an optimal Transmission Line Path (TLP) that suits different interests. Existing SDSS, however, are constrained to either overhead lines or earth cables, while no computational solution has been found so far, for how they can be combined with each other. Furthermore, the methods prevailingly used come with some conceptual issues that affect realistic TL planning. Therefore, we investigated several methods for making GIS-based TL planning more realistic, developing two approaches that are the first of their kind to identify an optimal corridor for a combined line (CL), based on two different decision models. Both approaches were included in a 3D Decision Support System (3D DSS), which consists of various algorithms for determining optimal TL corridors and paths on different voltage levels, regardless of the transmission technology. A user study conducted with nine experts revealed that the procedural approach was most supported and represented stakeholders’ interests most reliably when identifying optimal CLs. Our results provide evidence that the 3D DSS facilitates the planning of new TLs, fosters the profound analysis of different alternatives, and supports stakeholders when discussing the benefits and weaknesses of different TLP alternatives. Since experts have high confidence in benefiting from a computer-based semi-automated approach, SDSS will play an increasingly important role in future TL planning.
