With lifespans often spanning decades and relatively low maintenance costs, pumped storage hydropower is a long-term, cost-effective energy solution. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine. The system also requires power as it pumps water. From towering dams to intricate control systems, each component of a hydroelectric power plant significantly influences the overall cost of hydroelectric power generation. A closer look at these components helps reveal where costs originate and how efficiencies can be improved.
