    Auction approaches of long-term contracts to ensure generation investment in electricity markets: Lessons from the Brazilian and Chilean experiences
    (ELSEVIER SCI LTD, 2010) Moreno, R.; Barroso, L. A.; Rudnick, H.; Mocarquer, S.; Bezerra, B.
    The implementation of auctions of long-term electricity contracts is arising as an alternative to ensure generation investment and therefore achieve a reliable electricity supply. The aim is to reconcile generation adequacy with efficient energy purchase, correct risk allocation among investors and consumers, and the politico-economic environment of the country. In this paper, a generic proposal for a long-term electricity contracts approach is made, including practical design concepts for implementation. This proposal is empirically derived from the auctions implemented in Brazil and Chile during the last 6 years. The study is focused on practices and lessons which are especially useful for regulators and policy makers that want to facilitate the financing of new desirable power plants in risky environments and also efficiently allocate supply contracts among investors at competitive prices. Although this mechanism is generally seen as a significant improvement in market regulation, there are questions and concerns on auction performance that require careful design and which are identified in this paper. In addition, the experiences and proposal described can serve to derive further mechanisms in order to promote the entrance of particular generation technologies, e.g. renewables, in the developed world and therefore achieve a clean electricity supply.

    Distribution Network Rate Making in Latin America: An Evolving Landscape
    (IEEE, 2020) Moreno Vieyra, Rodrigo Andrés; Bezerra, B.; Rudnick van de Wyngard, Hugh; Suazo Martínez, C.; Carvalho, M.; Navarro Espinosa, Alejandro Andrés; Silva Montes, Carlos; Strbac, G.
    Following the trend observed in developed economies, various Latin American governments are committed to reducing greenhouse gas emissions, particularly in the power sector. In countries such as Chile, Peru, Colombia, Brazil, and Mexico, various regulatory policies have been issued to meet renewable-generation integration targets and satisfy the increasing demand from consumers for supply quality. Meanwhile, the integration of distributed generation (DG) in rural and urban areas as well as the increasing need to integrate electric vehicles (EVs) in urban areas are driving important reforms in the distribution sector.

    Ensuring Resource Adequacy with Auctions of Options and Forward Contracts
    (IEEE, 2007) Barroso, L. A.; Rudnick Van de Wyngard, Hugh; Moreno, R.; Bezerra, B.
    The implementation of auctions of long-term firm energy call options and forward contracts as part of the instruments adopted in emerging countries to ensure resource adequacy is discussed. These mechanisms are being implemented in Latin American nations (Brazil, Chile, Peru, El Salvador and Panama) and fast-growing economies in Europe such as Turkey. Brazil has led this process and in overall has auctioned about 25,000 average MW of contracts, involving about 65 billion USD in financial transactions, while Chile has carried out its first auction in 2006, involving about 1,300 average MW (30% of energy sales of the main interconnected Chilean system expected for 2010). Overall, this mechanism is proving to be adequate to attract investments and ensure resource adequacy.
