Abstract

We use a panel database of rate reviews conducted for U.S. electric utilities to assess how consumer advocates and

elected Public Utility Commission heads affect regulatory policy and utility strategy. We find first that utilities

postpone rate reviews in states with consumer advocates and elected commissioners. Second, we find that, after

controlling for observed and unobserved state characteristics, states with consumer advocates and elected

commissioners tend to grant lower returns on equity. Third, these institutions have differential impacts on different

types of consumer: consumer advocates are associated with higher residential-industrial rate ratios while elected

commissioners are associated with lower residential-industrial rate ratios.

In this paper the authors explain the source of the California electricity crisis, and provides a way to limit its cost and to provide a sound basis for a sound development of the sector.
 


Political Institutions and Electric Utility Performance: A Cross Nation Analysis

This paper analyzes the interaction of the institutional endowment of a country and investment in an industry with extremely high politicization and sunk costs: electric utilities. It links quantifiable differences in institutional environments across a wide sample of nations to investment decisions in their respective utility sectors. Providing credible commitments against arbitrary decision making by the state, that may impact on the profitability of these investments, through the existence of a number of independent constraints on executive behavior creates a better environment for utility investment. Managers considering investment in infrastructure projects should therefore evaluate the investment proposal not only on its explicit terms but also on the likelihood that the government will honor them.


The Introduction of Direct Access in New Zealand's Electricity Market

ABSTRACT

New Zealand introduced completely deregulated direct access in 1994. In this paper we provide the first assessment of one full year of direct access. We explore the determinants of direct access penetration across all the operating distribution companies. We find that the penetration of direct access in New Zealand responded quite clearly to economic incentives: companies that had unbalanced rates, that had high direct costs, that had high utilization rates, that had low load factors and low frequency of system interruptions had, on average, much higher rates of direct access penetration. These results took place even though this analysis is confined to the first year of operation, and in an environment in which the terms and conditions for direct access are negotiated between the distribution company and each individual direct access competitor. Thus, we suggest, that much of the current emphasis in the US in regulating terms and conditions of direct access is misplaced.

ABSTRACT

Various proposals to restructure electric power transmission systems for an open and competitive market rely on concepts such as nodal prices, congestion revenues, transmission rights, etc. Implicit assertions are made concerning the regulation of transmission access, properties of economic dispatch, and the operation of competitive power markets. In this paper we formulate these "folk theorems" as explicit mathematical assertions, prove the ones that are true and present counterexamples to those that are not. The concept of contract network is a centerpiece in Professor William Hogan's recent proposal for establishing a Poolco in the operation of a restructured electric utility. The contract network is based on nodal pricing and transmssion capacity rights. We provide a detailed analysis of these concepts and show that the use of nodal pricing for transmission systems and the assignment of transmission capacity rights are not compatible to the promotion of economic efficiency. 

Implementing Open Access: With Special Emphasis On Chile's Experience

ABSTRACT

Chile's reforms of the electricity sector are pathbreaking: elimination of monopoly franchise, deregulation of generation and of new generation investments, introduction of direct access for large users, break-up of vertically integrated utilities, centralized dispatch undertaken by a private entity, and the introduction of an innovative regulatory system based on marginal cost price and on the role of a putative efficient firm. After 15 years of reforms, it is time to ask whether it is possible to improve upon a system that is, quite clearly, among the most efficient and sophisticated in the world. This paper has two main purposes: first, to present the main shortcomings in Chile's transmission pricing policy and possible solutions; second, to show that this problem may not have a global optimal solution. 

Nodal Prices And Transmission Rights: A Critical Appraisal

ABSTRACT

The main purpose of this paper is to challenge several claims about the roles of nodal prices and transmission rights that have been accepted by some practitioners and academicians involved in the discussion on the transition towards a more competitive electricity sector, both in the U.S. and abroad. In particular, we demonstrate the inadequacy of pricing transmission services and compensating transmission owners on the basis of nodal price differences. Although such application of nodal prices may be suitable in simple (i.e., linear or radial) networks, in networks with parallel flow paths basing transmission pricing on nodal price differences is inappropriate. Moreover, without extensive regulation, transmission capacity rights based on a nodal price differences will not produce the right incentives for transmission investment or expansion, nor will they provide appropriate compensation for ownership of transmission assests or rights in a decentralized ownership network. We assert that new methods to deal with transmission ownership compensation and expansion are needed if the move towards a competitive wholesale electricity market is not to be bogged down in a regulatory quagmire.
