Cost-Benefit Analysis (CBA) is a well-established technique for Decision-Making (DM) in companies recently applied to Smart Grid projects whose impact can span over the electrical power system borders and cannot be easily monetized. Therefore, CBA lacks in describing the smart grid potential and Multi-Criteria Analysis (MCA) has been introduced for improving DM. The Webinar covers DM fundamentals focusing on MCA and CBA. Pros, cons and research gaps of each technique are analysed with the aid of real-world examples. Finally, a novel implementation of MCA-CBA is proposed with particular reference to Smart Grid application as proposed by ISGAN Annex 3.
