Summary

Hydropower with reservoirs is the only form of renewable energy storage in wide commercial use today. Storing potential energy in water in a reservoir behind a hydropower plant is used for storing energy at multiple time horizons, ranging from hours to several years. Pumped storage hydropower plants (PSH) are designed to lift water to a reservoir at higher elevation when the electricity demand is low or when prices are low, and turbine water to produce electricity when the demand is high and/or prices are high. PSH are often designed with a relatively high capacity to operate in turbine or pumping mode for only a few hours each. Technically, PSH are equipped either with a separate turbine and pump or with a reversible pump turbine. They often use artificial reservoirs with limited capacity for storing water. The environmental impacts of PSH are similar to those from conventional hydropower plants. In addition, PSH may lead to additional threats to biodiversity by transferring water and species between sites. Special attention must be paid to environmental impacts caused by fluctuating reservoir levels. Future challenges for PSH development are connected with technical improvements to increase the potential head and the flexibility in pump mode, and also business models, grid connection, environmental and societal issues related to the increasing need for energy storage, and balancing services followed by the increased deployment of renewable and intermittent energy sources. This chapter includes results from a case study on large-scale energy storage and balancing services from Norwegian hydropower to Europe, showing the technical potential to develop 20 000 MW of new hydro of which about 10 000 MW includes pumping. Also included is a system analysis study showing how wind power production can benefit from a nearby hydropower plant with pumping capacity.
