Abstract

Abstract: In liberalized electricity markets, the coordination and funding of transmission infrastructure are ongoing challenges. The challenge is to establish transmission tariffs that provide signals for efficient usage of the existing network and demand for new network capacity. Mexico's liberalized electricity market exemplifies the changing responsibilities in transmission planning. Through the adoption of locational marginal pricing, the Mexican market is well positioned to capture congestion costs and motivate efficient behavior. We highlight some of the potential problems that Mexico's currently planned approach and transmission tariffs could raise for generation location incentives. A long-term transmission plan can facilitate network optimization, with generation following the lead of transmission investment instead of the other way around. Highlights: Mexico's electric transmission cost allocation follows a fully socialized tariff. New clean energy generation creates a need for appropriate transmission investment charges. Integration of generation and transmission planning can achieve network efficiencies.
