pumped hydro storage

Singapore could import large quantities of low-cost solar power from neighbouring countries using undersea cables, with the indicative cost being competitive with gas generation. Unlimited world-class pumped hydro energy storage is available in neighbouring countries in the range 50-5000 GWh to support very large scale transmission.

A cross-Atlantic subsea pumped storage collaboration will seek to overcome the land-based challenges plaguing traditional pumped hydro storage technology.

With a total investment of around CNY12.5 billion ($1.76 billion), the project located in Jiande City, Zhejiang Province, is expected to commence power generation before 2030.

Scientists in Morocco have evaluated how hybrid wind solar plants may be combined with pumped hydro storage to power remote rural areas. The proposed system was found to have an LCOE $0.03831/kWh and a 86% use factor.

Indian hydropower provider SJVN said the pumped hydro storage project will be deployed across Darzo Nallah, a tributary of the Tuipui River.

Three pumped hydro projects that would deliver a combined 1,035 MW/9,480 MWh of dispatchable capacity are among six projects that have been declared critical, state-significant infrastructure by the New South Wales government in Australia.

The Happurg pumped storage plant was shut down in 2011 for safety reasons after the base of the upper reservoir was damaged. Uniper has carried out feasibility studies on the site, with a view to reconnecting it to the grid in 2028. The facility can store approximately 850 MWh of electricity in the form of pumped water.

According to projections from Norwegian consultancy Rystad Energy, Southeast Asia’s share of pumped storage hydropower is set to increase nearly eightfold in less than a decade – from 2.3 GW today to 18 GW by 2033. Rystad’s figures say that there is currently 2.7 GW of pumped hydro storage under construction, while the remaining 13.3 GW is in various stages of development.

The European Investment Bank (EIB) will conduct economic and technological feasibility studies on two Bulgarian pumped storage hydropower plants due to be operational by 2032. The projects will each add generation capacity of around 800 MW and will both come with a price tag of around €900 ($964) million.

The pipeline of pumped hydro storage projects in the Australian state of Queensland continues to grow, with Victoria-based renewables company BE Power announcing plans to develop an 800 MW/9.6 GWh project at Mount Alma near Gladstone.
