(PDF) Pumped Hydro Storage in the Brazilian Power Industry: A
This study evaluates whether pumped hydro storage (PHS) systems are economically competitive compared to natural gas thermal power plants in meeting peak load
In addition, few studies analyse PHS costs in Brazil. The analyses made so far refer mainly to technical and environmental aspects. Enhanced Pumped Storage (EPS) has been proposed as a potential solution for the current Brazilian energy system .
In Brazil, the limited variation in electricity prices along the load curve does not favour the operation of energy storage systems. Such projects are economically attractive when they can purchase energy at low prices and sell it during periods of high demand.
Understanding the economic competitiveness of PHS has profound implications for energy policy and infrastructure investment in Brazil. It informs decision-makers about potential pathways to enhance grid flexibility, reduce dependency on fossil fuels, and achieve environmental sustainability goals.
Historically, Brazil has depended heavily on hydroelectric power plants for electricity generation. While hydropower relies on rainfall patterns and can be intermittent, the construction of large reservoirs has traditionally helped to regulate water flow effectively.
