Irakasgaiaren azalpena eta testuingurua

The Energy Markets course explores the theoretical and empirical perspectives on energy markets architecture, and public policies affecting these markets. It discusses mainly aspects of the electricity power sector although the analytical tools learnt can be extended to other energy markets (brent, coal, natural gas, emissions,...).



The course examines price regulation, deregulation and liberalization, renewable energy promotion, the role of interconnections and self generation. Students use microlevel data from different energy markets worldwide to analyze the effect of different policies on the market structure, the level of competition and perspectives for future development.



In the practical sessions, the course combines microeconomic analysisis (eg. Cournot vs. Supply Function Competition) with empirical approaches based on time series (eg unit root analysis, VAR, …). R and Stata softwares are mainly used.



The course is located in the fourth block, just before the preparation of the Master's Thesis and after having completed the subjects of Algebra (first block), Optimization (first block) and Microeconomics (second block), which represent the preliminary basis necessary to undertake the course successfully. Basic concepts about time series, acquired in the Quantitative Methods subject (second block), are also recommended.



The course is related to the Sustainable Development Goals (SDG) of the United Nations 2030 Agenda in the following dimensions:



- SDG 7. Affordable and non-polluting energy. The course focuses on the study of energy markets, with a particular focus on renewable energies (Topics 1, 2, 3, 4).

- SDG 9. Industry, innovation and infrastructure. The course presents modeling of the energy industry, for spot and futures markets (Topics 5, 6).

The first call exam will be announced at the end of the second block courses. The exam has a weight between 40% and 60% of the total grade depending on the performance of the students submitting the homeworks.



In case the student does not submit all the homeworks, the final exam will be 100% of the final grade and it could include more questions.



Under exceptional circumstances that prevent face-to-face teaching and exams, the teaching and evaluation modalities may be adapted.

The second call exam will be announced at the end of the fourth block courses. The exam has a weight between 40% and 60% of the total grade depending on the performance of the students submitting the homeworks. Therefore, the grade of the homemorks still counts for the final grade.



In case the student does not submit all the homeworks, the final exam will be 100% of the final grade and it could include more questions.
