utility assets. After the sniper attack in April 2013 of the Metcalf substation in California, the North American Electric Reliability Corporation (NERC) has established a standard for physical security measures [2], that has been approved by the Federal Energy Regulatory Commission (FERC) on November 20, 2014. This standard requires that the transmission owners develop a risk assessment, identify and document critical substations and control centers. They must also develop plans to secure these facilities and identify ways to expedite recovery if an attack occurs.
This is where the GIS technology can bring some advantages to the utilities when considering these security aspects. Thanks to the development of GIS technologies, more compact substations can be implemented. The first part of the paper will illustrate it through examples of GIS evolution. With such compact arrangements, possibilities exist to better integrate these substations into the surrounding and to make them much less vulnerable to vandalism or attacks. The second part of the paper will show interesting solutions that can be implemented thanks to the GIS technology. As risks cannot be totally eliminated, in case of fault on any asset, unavailability of assets has to be kept to the minimum and this is depending on the technologies implemented. The third part of the paper will highlight some key issues to consider when developing a GIS substation to maintain the highest operation continuity (also called service continuity).
