    • A delicate balance in South America 

      Rudnick, Hugh; Nobrega Barroso, Luiz Augusto; Valenzuela Mocarquer, Luis Sebastian; Bezerra, Bernardo Vieira (02/07/2008)
      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 ...
    • Auction approaches of long-term contracts to ensure generation investment in electricity markets: lessons from the Brazilian and Chilean experiences 

      Moreno Vieyra, Rodrigo; Nobrega Barroso, Luiz Augusto; Bezerra, Bernardo Vieira; Valenzuela Mocarquer, Luis Sebastian; Rudnick, Hugh (01/10/2010)
      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 ...
    • Balance of power 

      Valenzuela Mocarquer, Luis Sebastian; Nobrega Barroso, Luiz Augusto; Rudnick, Hugh; Bezerra, Bernardo Vieira; Veiga Pereira, Mario (01/09/2009)
      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. ...
    • Bidding strategies with fuel supply uncertainty in auctions of long-term energy call options 

      Bezerra, Bernardo Vieira; Nobrega Barroso, Luiz Augusto; Veiga Pereira, Mario (01/05/2011)
      This work develops a stochastic optimization model for the creation of a bidding strategy for a generator in an energy call option auction similar to Brazil's, i.e., where the bidder can offer both the premium and the ...
    • Expansion pressure: energy challenges in Brazil and Chile 

      Bezerra, Bernardo Vieira; Valenzuela Mocarquer, Luis Sebastian; Nobrega Barroso, Luiz Augusto; Rudnick, Hugh (01/05/2012)
      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 ...
    • Stochastic long-term hydrothermal scheduling with parameter uncertainty in autoregressive streamflow models 

      Bezerra, Bernardo Vieira; Veiga, Alvaro; Nobrega Barroso, Luiz Augusto; Veiga Pereira, Mario (01/03/2017)
      The optimal scheduling of hydrothermal systems requires the representation of uncertainties in future streamflows to devise a cost-effective operations policy. Stochastic optimization has been widely used as a powerful ...
