Wind Energy Storage
Published in Thomas Corke, Robert Nelson, Wind Energy Design, 2018
Pumped storage hydroelectricity is a method of storing and producing electricity to supply high peak demands by moving water between reservoirs at different elevations. The principle is that during times of low electricity demand, the excess generation capacity is used to pump water into a reservoir at a higher elevation. When the electric demand is higher, the water is released back into the lower reservoir. In doing so, the water is run through a turbine that generates electricity. In this process, a reversible turbine/generator acts as both a pump and a turbine. Figure 10.8 illustrates the process. Some facilities use abandoned mines as the lower elevation reservoir, but many use the height difference between two natural bodies of water or artificial reservoirs.
Hydropower, a catalyst for energy transition in Europe

Jean-Jacques Fry, Mark Morris, Anton Schleiss
As editor, Jean-Jacques Fry introduced the SIR. The three highest priority actions identified were for stakeholders to improve (1) the flexibility market, (2) public awareness, and (3) regulations. Thirty-eight high-priority strategic actions are grouped under three guidelines: Provide economic and legal support for flexibility and storage through improving flexibility markets, better practices for investing under uncertainty and developing a more relevant regulatory framework.Preserve biodiversity and enhance river ecosystems through best practice in sustainability and biodiversity protection, improved knowledge of environmental impacts, application of innovative compensation measures and development of holistic approaches that promote synergy and trade-offs.Raise public awareness through communication and dissemination, increasing societal resilience and local employment, developing best practices for sustainability and win–win situations, increasing security, decentralisation and independence of the European energy system through Pumped-Storage Hydroelectricity (PSH) and launching a collaborative platform for hydropower.
The Key Attributes, Functional Requirements, and Design Features of Resilient Nuclear Power Plants (rNPPs)
Published in Nuclear Technology, 2018
Another option would be to incorporate some form of electric load dump for some portion of the load. This concept of course underlies the use of pumped storage hydroelectricity, electric-driven flywheel storage systems, etc. However, it is difficult to envision how such systems could be acceptably interfaced to the rNPP from both the technical and economic perspectives.
