We show that project evaluation should be based on free cash flows at nominal prices. We present a case where the results from the constant price method are biased upwards and there is a risk to accept bad projects. It is a widespread practice to evaluate projects at constant prices. With an...

We present a hybrid mechanism application for the electrical system network expansion in Mexico, United States and Canada. The application is based on redefining the transmission output in terms of "point-to-point" transactions or financial transmission rights (FTRs); rebalancing the fixed and...

This paper presents an application of a mechanism that provides incentives to promote transmission network expansion in the electricity system of the Ontario province. Such a mechanism combines a merchant approach with a regulatory approach. It is based on the rebalancing of a two-part tariff...

We analyze the effects on social welfare of two different processes of transmission network expansion planning. A first model (integrated model) considers decisions on electricity generation and transmission as interdependent activities. A second model (disintegrated model) assumes that these...

Estudiamos esquemas de tarificación de la transmisión eléctrica en un contexto donde los precios de la electricidad son determinados en una bolsa de energía. Se pone énfasis en el impacto que significa traspasar, ya sea a través de un cargo fijo mensual o

One of the critiques to the regulatory framework of the Chilean electricity sector is the lack of flexibility for regulated prices (nodal prices) to adapt to changes in supply and demand. We develop a simple model to estimate welfare losses when using uni

En este trabajo se realiza un estudio de los cambios en la productividad explicados por el cambio técnico en el sector eléctrico español durante el período de vigencia del sistema regulatorio denominado Marco Legal y Estable. Para ello, hemos estimado una función de costes cuadrática de...

A key characteristic of regulatory schemes in Latin America is its virtual absence of mechanisms for coping with outages in the supply of public utilities. This paper presents such a mechanism, which has the advantage of being complementary to the medium

Los factores de distribución GGDF y GLDF son un método atractivo para prorratear los peajes que deben pagar los usuarios de sistemas eléctricos de transmisión. Sin embargo, se demuestra que el método no es suficiente para definir un único prorrateo. Los g
