  Optimizing dam siting in hydropower systems using a multi-objective optimization approach
  Hydropower systems can provide two dierent electricity services: base load and peak load generation or peak load generation only (Egré and Milewski, 2002). The former is often found in regions where hydropower is abundant, while the latter is found where hydropower complements other energy sources. In a region where hydropower oers base load and peak load generation, the increase in generation capacity can be readily seen as benecial in terms of energy reliability. On the other hand, hydropower plants are always associated with reservoirs, one of the main causes of social and environmental impacts. In the last years, hydropower projects have been facing many challenges around the world, frequently related to public expectations regarding social and environmental performances (Klimpt et al., 2002). Decision-makers often choose the best set of hydropower plants to be built in a given river or watershed based on optimization models. These models can be an important tool not only to decide what might be the best policy, but also to communicate the main stakeholders why a given policy was chosen and what were the main variables that lead to that decision. In addition, by using a multi-objective model that considers social-environmental aspects as a goal, and not as a constraint, it might be possible to better assess the trade-os that hydropower expansion presents. The main goal of this research is to develop a multi-objective decision-support model that may be used by policy makers to decide where to build new hydopower plants, considering social-environmental aspects explicitly as an objective function. Another desired goal is to identify the main aspects that might represent a barrier in this process, in order to try to overcome them or indicate that increase in energy/storage might not be possible, showing the main reasons and consequences of this outcome.
