As the transition to a clean energy future rapidly unfolds, this flexible technology will become even more important for a reliable, affordable and low carbon grid, write IHA analysts Nicholas Troja and Samuel Law. "Anything that can go wrong will go wrong". That old adage, Murphy''s law, must seem appropriate for many power grid

Hitachi Energy has been innovating static frequency converter solutions for more than 40 years. SFCs have a unique ability to control voltage, frequency, and power flow. This technology makes them crucial to several power applications, particularly rail, grid interties, shore-to-ship, and pumped hydro storage. SFCs are based on Hitachi Energy
The new plant is scheduled to go into operation in mid-2023. The four Pelton turbines with a total rated output of 44MW that are currently used in the Ritom plant will be replaced by much more powerful generating units in the new facility. To this end, Voith will supply two Pelton 60MW turbines and a 60MW storage pump.
Figure 2: The plot above visualises (logarithmic scale used) the estimated discharge durations relative to installed capacity and energy storage capacity for some 250 pumped storage stations currently in operation, based on information from IHA''s Pumped Storage Tracking Tool. The vast majority of pumped storage stations have a discharge
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.

Image: Alpiq. A pumped hydro energy storage (PHES) plant with a capacity of 20GWh in Valais, Switzerland will begin operations on Friday 1 July. The launch of the Nant de Drance plant, which sits 600m below ground in a cavern between the Emosson and Vieux Emosson reservoirs, marks the conclusion of 14 years of construction.
Pumped storage hydro power stations require very specific sites, with substantial bodies of water between different elevations. There are hundreds, if not thousands, of potential sites around the UK, including disused mines, quarries and underground caverns, but the cost of developing entirely new facilities is huge.
