The emerging of BIM (Building Information Modeling) techniques will change traditional procedures of design and maintenance for electric substations. In addition, Computational Holography, supported by wearable computers, has the potential to allow simultaneous engineering work, based on mixed reality and computer vision capabilities. It is believed that this set of tools will increase engineering design decisions. In this work, we propose a set of techniques to support a complete substation design, which is created by using BIM concepts that explore the Holographic world benefices. Experiments have shown that the coupling of these techniques has the potential to reduce the learning curve of the users, since it changes the way of collaboration among different professional specialists considering simulation intents.

The profits and benefits offered by Virtual Reality technology had drawn attention of professionals from several scientific fields, including the power systems', either for training or maintenance. For this purpose, 3D modeling is evidently pointed out as an imperative process for the conception of a Virtual Environment. Before the complexity of Hydroelectric Power Plants and Virtual Reality's contribution for the Industrial area, planning the tridimensional construction of the virtual environment becomes necessary. Thus, this paper presents modeling techniques applicable to several hydroelectric structures, aiming to optimize the 3D construction of the target complexes.
