- ItemBenchmark regulation and efficiency of electricity distribution in a restructured power sector(IEEE, 2004) Rudnick van de Wyngard, Hugh, 1947-; Sanhueza Hormazabal, Raúl EdgardoA growing challenge in the restructuring of the electrical sector, where competition is introduced in the generation area, is to achieve equivalent efficiencies in the electrical distribution service, an activity that develops in a monopolistic environment. This summary discusses this challenge and the regulatory methodologies under application and/or evaluation that try to take to that efficiency improvement. The complementary presentation will give an overview of such tariff regulations and world-wide experiences. Special emphasis will be given to the concepts of model companies and distribution added value and their application in Latin America.
- ItemBenchmark regulation and efficiency of electricity distribution: strengths and weaknesses(IEEE, 2007) Rudnick van de Wyngard, Hugh, 1947-; Mocarquer, S.A growing challenge in the restructuring of the electrical sector, where competition is introduced in the generation area, is to achieve equivalent efficiencies in the electrical distribution service, an activity that develops in a monopolistic environment. Chile has had an experience of over 20 years of applying benchmark price regulation to its distribution companies. This summary discusses the strengths and weaknesses of the Chilean benchmark scheme .
- ItemHydro developments, generation options and the environment in Latin America(IEEE, 2008) Barroso, Luiz Augusto; Hammons, Tom; Rudnick van de Wyngard, Hugh, 1947-This paper provides a concise outlook of the hydro developments, generation options and the environment in Latin America. Various public debates have occurred in recent decades in industrialized economies over the energy supply future. Much greater attention is now being paid to these issues in developing economies. The debates are generally about the comparative economic, environmental and social trade-offs, and public acceptability of the various nuclear, thermal, hydro, and alternative generation options; and increasingly, about the potential role and contribution of demand management options. Panelists that have been deeply involved in this debate in their countries will discuss topics such as the main trends and issues for different electricity supply options in Latin America considering their social and environment implications, and sustainable development practices.
- ItemLessons from the 2010 Chilean earthquake and its impact on electricity supply(IEEE, 2010) Araneda, J.C.; Rudnick van de Wyngard, Hugh, 1947-; Miquel Duran, Pedro EnriqueSecurity of energy supply is a main concern worldwide, given the strong dependence on society functioning on its adequate delivery. Surges in fuel prices, political conflicts, wars and natural disasters threaten directly energy supply, and countries look at ways to protect themselves. On February 2010 an 8.8 Richter scale earthquake hit the central part of Chile and a tsunami following the earthquake hit coastal areas, affecting the most populated area of the country. Main supplies collapsed, electricity, water, gas, telephones, contributing to make matters worse for the suffering population. This paper illustrates events that took place in electricity supply during and after the earthquake in Chile, its impact on the generation, transmission and distribution infrastructure, and the lessons to be learned. The challenges in reconstruction are also discussed. The main interconnected system, generation and main transmission grid, was able to resume partial operation within a few hours, although in a weak condition. Damage took place in some main substations, and alternative paths and operational conditions had to be found. Security criteria had to be degraded in the system operation and handling of the main grid. The Chilean codes impose strict anti seismic standards for all electricity infrastructure construction, but the earthquake strength still produced damage in some grid installations. However, the most severe damage took place in the distribution networks, vast areas were left with no supply for weeks, including the large city of Concepcion being severely affected.
- ItemRisk allocation for efficient and timely transmission investment under markets with high demand growth(IEEE, 2009) Moreno Vieyra, Rodrigo Andrés; Rudnick van de Wyngard, Hugh, 1947-Under the need for anticipatory efficient investment in transmission, several problems arise at the regulation and incentives level; economies of scale justify carrying out larger initial transmission investments that existing generation and demand may be not willing to pay. This problem is increased with high demand growth where anticipatory investment is crucial for converging to an efficient electric system. Without anticipatory investment, the net number of lines in the long term may be duplicated/triplicated and/or the cost of reinforcing may sharply increase as lines were not initially built to be (easily) upgraded. This cost increase, assumed by generators in the case of additional lines, can ultimately create a barrier to entry for new agents and therefore constrains competition in the market while also impacting end user tariffs. In this paper a formal methodology is proposed to allocate the extra funds needed to build upgradeable additional lines. This is applied to a particular case in the Chilean electricity market.
- ItemRisk responsibility for supply in deregulated electricity markets - the Chilean case(IEEE, 2003) Rudnick van de Wyngard, Hugh, 1947-The presentation reviews the supply problems faced in the Chilean electricity market oven recent years, and how market and regulations have worked in relation to allocating the responsibility for supply. The risks associated with that responsibility are discussed and how Chile has taken actions in this regard, and the consequences of those actions. The Chilean regulation transfers full responsibility to suppliers. In theory, different types of penalties and compensations are applied when load is not supplied; in practice they have been difficult to put into operation. The presentation analyzes the performance of this approach, the crisis faced in 1998-1999 and the changes introduced to the regulation due to that crisis. Conclusions on the effectiveness of the regulations and the changes are developed as well as an assessment of unexpected impacts in the market.
