Background

Pérez-Arriaga was born in Madrid and went on to graduate as Electrical Engineer from the ICAI School of Engineering. He earned an M.S. and a Ph.D. in Electrical Engineering, both from the Massachusetts Institute of Technology in 1978 and 1981 respectively. After completing his Ph.D., Pérez-Arriaga became professor at the ICAI School of Engineering. In 1984 he founded the Institute for Research in Technology (IIT) at Comillas Pontifical University, being its Director until 1994. Since 2009 he rejoined the MIT (Engineering Systems Division, CEEPR, and MIT Sloan School of Management), where among other activities he teaches the graduate course “Engineering, Economics and Regulation of the Electric Power Sector”. He is also Director of Training at the Florence School of Regulation European University Institute in Florence, Italy. Beyond his role as professor, he has played an active role in the liberalization process of the electric power sector, not only in the implementation of the European Internal Market for Electricity, being one of the precursors of the Electricity Regulatory Forum (Florence) of the European Commission but also in the Latin American context (President of the Advisory Council of the Central American Electricity Market until 2005). He served as Commissioner in the Spanish Electricity Regulatory Commission (1995-2000) and later as Independent Member of the Single Electricity Market Committee of Ireland (2007-2012). Currently he is Member of the Board of Appeal of the Agency for the Coordination of Energy Regulators (ACER) in the EU, and Review Editor of the 5th Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). He has also rendered consultant services for governments and regulatory authorities, international institutions, industrial associations and utilities in over 30 countries.

Relevant academic contributions

The research activity of Pérez-Arriaga has been focused on the analysis of electric power systems, but it has been in permanent evolution. Through different stages, his research interests have included modeling, control and stability analysis of power systems; optimization of expansion and operation of power generation systems; transmission and distribution of electricity; and electricity sector regulation including issues related to transport, supply security, the design of regional wholesale markets and rates and, more recently, the sustainability of energy models and universal access to energy.

Mid-1970s to mid-1980s: Power systems control and stability analysis

His contributions in the field of electrical engineering began with the completion of his PhD at MIT under the supervision of Prof. Fred Schweppe, in which he formulated a new technique for the dynamic analysis of small perturbations of electric power systems known as Selective Modal Analysis.[1] This analytical framework allows approaching large and complex linear time-invariant dynamic system problems (such as dynamic stability analysis, or the determination of coherent generator groups and dynamic equivalents in transient stability studies) through a reduction technique that extracts the relevant quantitative and qualitative information. This framework was later applied intensively to solve different power system stability and control problems, such as the analysis of the oscillatory stability and control,[2] subsynchronous resonance or multi-area analysis of small signal stability.[3]

Mid-1980s to mid-1990s: Models for power systems and industrial applications

In the late 1980s and early 1990s, his research was focused on the development of new algorithms and methodologies to support the operation and planning of electric power systems. Among other contributions, he developed pioneering models for computation of spot prices in interconnected power systems and decomposition approaches to tackle optimal reactive power planning problems.[4] During this period he also contributed to computer-aided optimization design of electrical machines and other industrial equipment and to the development of expert systems with applications to the design and incipient default detection in industrial systems.

Mid-1990s to mid-2010s: Economics and regulation of electric power systems and markets

In the early 1990s, in the context of the Argentinean power sector restructuring, he began working on the analysis of the best regulatory methodologies for pricing power transmission services, formulating the principle of beneficiary pays for network cost allocation. Since then, he has devoted a major part of his research activities to the regulation and restructuring of the power industry.

He carried on with the seminal works of his mentor Prof. Schweppe on marginal pricing theories applied to power systems; on the generation side, he formulated the foundation for wholesale pricing considering generation operation and planning constraints[5] and identifying the reasons for mismatches in capital cost recovery with marginal generation prices. On the transmission side, he demonstrated why marginal prices fail to recover the total incurred network costs.[6] Later on, he added major contributions to the security of supply debate, formulating in the context of the redesign of the Colombian capacity payments mechanism in 1999 the reliability options mechanism,[7] the base of the capacity auction mechanisms later implemented in Colombia and New England. He has also worked intensively on the regulatory design of regional markets (both in Central America and in European Union) as well as on end-user tariff design. In 2013 he edited the book “Regulation of the Power Sector” (Springer-Verlag), used as textbook in his MIT course as well as in the annual training program for energy regulators of the Florence School of Regulation of the European University Institute.

Currently he is Principal Investigator of the Comillas University - Massachusetts Institute of Technology Electricity Systems Program Archived 2014-01-03 at the Wayback Machine. He was the principal investigator of the MIT Utility of the Future study, published in 2016.

Mid-2010s to date: Universal energy access

Pérez-Arriaga's current research interests are focused on power sector regulation and master electrification planning for universal energy access and energy for growth in low- and middle-income countries (LMICs). He is the principal investigator of the MIT-Comillas Universal Energy Access Lab. The group does research in LMICs, builds computational models for electrification planning, uses machine learning and remote sensing techniques for electricity demand and access rate estimation, and provides regulatory advice. Pérez-Arriaga directs the Global Commission to End Energy Poverty, developing the Integrated Distribution Framework (IDF). In 2023, Pérez-Arriaga founded the African School of Regulation.
