Last updated: 17 June 2024. The NZ Battery Project was set up in 2020 to explore possible renewable energy storage solutions for when our hydro lakes run low for long periods. A pumped hydro scheme at Lake Onslow was one of the options being explored. The Government stopped the Lake Onslow investigations in late 2023.
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 needs to play. It is a mature, cost-effective energy-storage technology capable of delivering storage durations in the critical 10–50 hour duration bracket, at scale, to cover fluctuations associated with a …
This paper introduces a utility-scale ESS based on pumped hydro storage (PHS), which is the most prevalent and mature example of medium–large scale energy storage. This commercially proven storage method currently accounts for over 95% of the total storage capacity being utilized in the world [6] .
As the introduction described, the pumped storage hydropower can effectively suppress fluctuations from wind and solar power and improve the absorptive capacity of power grid to them. Hence, the pumped storage units will operate in non-rated conditions frequently and unstably, which will produce the unpredicted fatigue failures to …

Seasonal pumped hydropower storage: addressing energy and water storage challenges [ 1 ] defines seasonal storage as "The ability to store energy for days, weeks, or months to compensate for a longer-term supply disruption or seasonal variability on the supply and demand sides of the energy system (e.g., storing heat in the summer …
Pumped hydro energy storage could be used as daily and seasonal storage to handle power system fluctuations of both renewable and non-renewable energy (Prasad et al., 2013). This is because PHES is fully dispatchable and flexible to seasonal variations, as reported in New Zealand ( Kear and Chapman, 2013 ), for example.
