    A delicate balance in South America
    (2008) Rudnick, Hugh; Barroso, Luiz; Mocarquer, Sebastian; Bezerra, Bernardo
    This article deals with the challenges of balancing the need for hydroelectricity with the impact on the environment. Economic efficiency, energy security, and environmental sustainability are concerns that must be considered in any energy policy in any given country. These key aspects remain challenged currently in South America. High energy consumption growth worldwide rising fossil fuels prices, strong environmentalist pressure toward reducing greenhouse gas effects, and promotion of renewable energy production have been a common challenge in South American energy markets. The development of vast unexploited hydroelectric resources is also at the center of attention, where its renewable character is being confronted with its environmental impact.

    Balance of power
    (2009) Mocarquer, Sebastian; Barroso, Luiz; Rudnick, Hugh; Bezerra, Bernardo; Pereira, Mario
    This paper discusses the challenges in the procurement of electricity. The primary challenge faced by the countries in Latin America is to ensure sufficient capacity and investment to reliably serve their growing economies. The turn of the century brought different challenges to the energy supply in the region and to its market policy emphasis, coupled with a worldwide rocketing up of fuel prices.

    Expansion Pressure: Energy Challenges in Brazil and Chile
    (2012) Bezerra, Bernardo; Mocarquer, Sebastian; Barroso, Luiz; Rudnick, Hugh
    In Latin America, primary energy demand is projected to grow on average by 1.7% per year and to reach 830 million tons of oil equivalent (mtoe) by 2035, according to the International Energy Agency's 2011 World Energy Outlook. Demand for renewables in the power generation sector in the region will double over that period, reaching nearly 140 mtoe in 2035. Furthermore, the IEA projects that biofuels use in road transport will increase by more than 4% per year, reaching 1 million barrels per day (mb/d) by 2035, representing around 25% of fuel consumption in the sector. The economic giant in the region, Brazil, will increase its primary energy consumption to 420 mtoe in 2035, representing more than half of the regional total.

    Flexible Connections: Solutions and Challenges for the Integration of Renewables in South America
    (IEEE, 2012) Rudnick van de Wyngard, Hugh; Barroso, Luiz; Llarens, Daniel; Watts Casimis, David; Ferreira, Rafael de Sà
    Feed-in tariffs, quota systems, and auction schemes are all used to stimulate NCRE growth in South America. These methods present common challenges in terms of development, operation, and transmission. Common solutions to these challenges are being developed, and Brazil is leading the way with its rapid incorporation of NCRE. The existing market, commercial, and regulatory frameworks may present barriers to the timely and cost-effective connection of renewable generation, as they may not be flexible and agile enough to allow for the connection of smaller, dispersed generators with short construction times. This has led to the revision of network tariff arrangements, including the review of network operating and design practices, security standards, access regimes, investment incentives, cost recovery, and rates. The experiences presented in this article illustrate some of the key initiatives and solutions being proposed to address the challenge of unlocking the doorway for renewables. Further concerns need to be addressed, however, with a broader vision that seeks convergence to an efficient, 21st-century, low-carbon energy system through more cooperative development of renewables and the required transmission assets.

    Zero-Marginal-Cost Electricity Market Designs: Lessons Learned From Hydro Systems in Latin America Might Be Applicable for Decarbonization
    (2021) Barroso, Luiz; Munoz, Francisco D.; Bezerra, Bernardo; Rudnick, Hugh; Cunha, Gabriel
    Large reductions in the cost of renewable energy technologies, particularly wind and solar, as well as various instruments used to achieve decarbonization targets (e.g., renewable mandates, renewable auctions, subsidies, and carbon pricing mechanisms) are driving the rapid growth of investments in these generation technologies worldwide.
