Profile

Deputy Director Financial-Economic Regulation and Regulated Prices at National Markets and Competition Commission (CNMC)

Ismael Bahillo holds a B.A. in Economics from Universidad de Valladolid and a master degree in Economics and Finance at CEMFI (Bank of Spain Foundation).

Mr Bahillo started his career as an Energy Analyst at NERA's Madrid office in July 2000. Since he joined NERA, he specialized in regulatory, financial and strategic issues concerning gas and electricity markets in Spain and in other European countries. In the gas sector, he analyzed existing and proposed gas legislation; carried out in-depth analysis of tariff systems and access regimes in various European countries; designed the regulated remuneration mechanism for gas transmission, storage, and distribution companies for a European country, including the calculation of the WACC for regulated activities; and advised on the corresponding final and access tariffs. In the electricity sector, he worked on the design of marginal cost-based electricity tariffs for the peninsular electricity system. He also advised in themes of commercial and corporate strategy, including the valuation of distribution companies and the profitability of regulated activities.

In 2011, Ismael Bahillo joined the State Secretary of Energy within Spain's Ministry of Industry, Tourism, and Trade as Advisor, responsible for the design and coordination of the regulation in the energy markets in Spain, with a special focus on the hydrocarbons sector.

In February 2012, he joined the former Comisión Nacional de Energía, CNE (National Energy Commission) as Deputy Director for Regulation. At the end of 2013, the merger of various Regulatory Commissions in Spain resulted in the creation of the Comisión Nacional de los Mercados y la Competencia, CNMC (National Markets and Competition Commission). Within this process, Ismael Bahillo was promoted to Deputy Director for Economic-Financial Regulation and Regulated Prices in the Energy Directorate at the CNMC.
