Ellis emphasises the high cost of curtailment, noting that “in 2023 curtailment costs reached £920M due to grid limitations”. A report for Drax, published in May
pumped hydro capacity in the NEM is not required for many years. Pumped hydro considered by the Battery of the Nation initiative considers storage sizes ranging from 7 to 48 hours. ISP modelling considered storage as having only 2 hours storage in the case of battery energy storage systems and 6 hours in the case of pumped hydro.
Hydropower operations and maintenance costs are often 3–5% of the capital value of the asset. Over the life of the asset (possibly more than 70 years) this adds up to significant cost. Unforseen failures and poor performance will increase these costs even further.

Pumped storage hydro (PSH) must have a central role within the future net zero grid. No single technology on its own can deliver everything we need from energy storage, but no other mature technology can fulfil the role that pumped storage
Pumped storage hydro (PSH) is a large-scale method of storing energy that can be converted into hydroelectric power. The long-duration storage technology has been used for more than half a century to balance demand on Great Britain''s electricity grid and accounts for more than 99% of bulk energy storage capacity worldwide.
PHES has experienced thriving development for the fact of flexibility and affordability, and the robust adjustability across the variable timescale effectively alleviates the intermittency and stochasticity of VES (Schleicher & Oztekin, 2015).Nevertheless, it is these features help integrate VES, also bring challenges to the steady operation of pumped storage
Long Development Time: From planning to operationalisation, pumped storage hydropower projects can take many years to develop. This long lead time can be a disadvantage in rapidly changing energy markets.
The highly capital-intensive nature of hydro and its long lifetime therefore makes its harder to attract private capital to build it. Of all the hydropower installed globally between 2000 and 2020, 70% was publicly owned and operated.
Snowy Hydro power station, New South Wales, Australia. The 2024 ISP forecasts the need for 36 GW/522 GWh of storage capacity in 2034-35, rising to 56 GW/660 GWh of storage capacity in 2049-50.

A team of researchers found 35,000 pairs of existing reservoirs, lakes and old mines in the US that could be turned into long-term energy storage – and they don''t need dams on rivers.
The technology also has a much longer technical lifetime (50–100 years). Unsurprisingly, pumped hydro energy storage comprises the vast majority of global storage power capacity and global storage energy volume.
Energy Loss: While efficient, pumped storage hydropower is not without energy loss. The process of pumping water uphill consumes more electricity than what is generated during the release, leading to a net energy loss. Water Evaporation: In areas with reservoirs, water evaporation can be a concern, especially in arid regions.
While the upfront investment is relatively large, there are huge potential cost savings, many of which can be passed on to customers. A recent study by Imperial College found that just 4.5 GW of new long-duration pumped hydropower storage with 90 GWh of storage could save up to UK£690m per year in energy system costs by 2050.
