    Hydro 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.

    Risk 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.

    Risk 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.
