The course is aimed at providing the basic background needed for understanding the national and international energy equilibria, with reference to economics and a focus on electricity. The course discusses the main economic issues of electricity as an energy commodity, considering the related markets. The course introduces the basic concepts about the operation of competitive electricity markets and the financial analysis of the investment project in the electro-energetic field. The key-aspects in the management of the power systems in the framework of the “energy transition” from fossil fuels to Renewable Energy Sources (RES) are introduced.

The student, at the end of the course, will be able to understand, within national and international energy scenarios, the interplay between energy and economic issues. He or she will be aware of the basic concepts of the economic and financial analysis and of the structure and operation of competitive electricity markets, being able to understand and interpreting the main related issues. The student will acquire a basic understanding of the key-issues, from an economic perspective but not limited to that, of the undergoing energy transition.

The course is organized in lectures and practical works. Lectures introduce to the students the key-concepts, also with an interactive approach. Practical work, in the classroom and ICT lab, will provide some insight, with the direct involvement of the students, on the topics presented in the lectures, also through general computational SW (Matlab) and dedicated power systems SW (Powerword). Practical work topics: 1.Technical-economic aspect of electrical energy, 2.Microeconomics and economic metrics, 3. Market clearing without network constraints, 4. Market clearing with network constraints and optimization problems, 5. Financial analysis of energy investments.
