Storage and pumped-storage plants in Switzerland
Table 3 shows the results for Switzerland compared to the existing plants. In 2010, SHP accounted for about 6.3% of the hydropower installed capacity. However, for storage schemes SHP accounted for only 1.3 % of the installed capacity and for pumped-storage schemes even less with 0.7%. There is potential to increase these figures.

Pumped-storage hydroelectricity
Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation.

What is Earthwork in Construction?
Introduction. Earthwork is a fundamental aspect of construction that involves the excavation, movement, and compaction of soil and rock to create a stable foundation for building structures. It is the first step in the construction process, preparing the ground for the construction of roads, bridges, buildings, and other infrastructure.
