Andrés Chambouleyron

Managing Director

Andrés Chambouleyron is a managing director at Berkeley Research Group.

He has twenty-five years of experience as an economist, valuation expert, and consultant for public utilities (electricity, natural gas, water and sanitation, and telecommunications) and other regulated and non-regulated businesses. His work involves economic analysis, pricing and rate setting, valuation, business advisory, regulatory design and analysis, and damage assessment. In the public sector, Dr. Chambouleyron was economic advisor to Argentina’s secretary of Communications (2000–2001), where he helped design and implement the country’s new regulatory framework (i.e., interconnection, spectrum management, universal service, and licensing regimes); and advisor to Argentina’s minister of Economy in 2001 on regulatory issues.

Before joining BRG, Dr. Chambouleyron was undersecretary of tariff policy at Argentina’s Ministry of Energy and Mining, where he designed and implemented a subsidy-reduction program to both electricity generation and natural gas production and a social tariff regime for low-income families. After winning a public contest and getting the approval of Argentina’s National Congress, he became chairman of the board of Argentina’s National Electricity Regulator (ENRE), which regulates rates and quality of service for two electricity distribution companies in the Buenos Aires metropolitan area (six million users), one 500 KV electricity transmission company (fifteen million users), and seven 132 KV regional transmission companies.

Dr. Chambouleyron has been involved both as case manager and expert witness in twenty arbitration cases assessing damages for both defendants and respondents under the rules of ICSID, ICC, and UNCITRAL in Latin American, Europe, the US, and Canada. He has worked and provided written or oral testimony in sectors ranging from electricity generation, transmission and distribution, natural gas and oil production, transportation and distribution, water and sanitation services, telecommunications and satellite services, fish meal manufacturing, pesticides, and car financing services. He has provided consulting services to both private companies and regulatory authorities throughout Latin America on regulatory issues such as interconnection rates and tariffs for both fixed and mobile telecommunication operators, X-productivity offset factors, and tariff calculation for price-cap regimes in telecoms, electricity and natural gas distribution companies, weighted average cost of capital estimation (WACC) for electricity and natural gas distribution and transportation companies.

Dr. Chambouleyron’s research on pricing and regulatory issues has been published in several professional journals. He has collaborated in writing three chapters in three books related to regulatory and pricing issues. He has taught courses in microeconomics, industrial organization, and regulation at both undergraduate and graduate levels in local universities.
