The Slovakian regulatory agency –RONI– needed a model for the redesign of the wholesale electricity market, including the design of the market rules and regulation of transmission and generation in the context of privatization. Mr. Pabon co-led the development of the specifications of the price regulation formula for the transmission business and the guiding principles for transmission price reviews, calculation of the revenue requirement, and development of guidelines for determining cost-reflective transmission tariffs and procedures for ensuring non-discriminatory access to the transmission system.
