Pumped hydro storage sites to support a 100% renewable electricity grid
With the support of the Australia Indonesia Centre we have identified 657 potential sites across Bali for pumped hydro energy storage (PHES), with a combined potential storage capacity of 2,300 Gigawatt-hours.
Pumped hydro energy storage is a technique to store energy produced by electricity generation. Using electricity generated from renewable energy such as solar power and wind, the potential sites for PHES that we identified in Bali would be enough to support a 100% renewable Indonesian electricity grid and more.
Solar photovoltaics (PV) and wind are now the leading electricity generation technologies being installed worldwide each year. Gas and coal are in third and fourth spots respectively. PV is accelerating away from other energy generation technologies because it’s cheaper, scalable and produces no greenhouse gas emissions, and because there is vast availability of sunshine.
