We will soon undertake further Indonesian site searching, and expect to find as many sites as in Australia (where we found 22,000 good sites). Of course, there is also large potential on other islands. Most of the 657 potential PHES sites we have identified in Bali are off-river. Figure 2 shows the location of prospective areas – the red areas are highly prospective. PHES can readily be developed to balance the electricity grid with any amount of solar and wind power, all the way up to 100%. Indonesia has enormous pumped hydro storage potential. This smooths out adverse local weather, greatly reducing the amount of storage needed.įigure 3: Upper reservoir pumped hydro sites in Bali. provide strong interconnection of the electricity grid between regions using high-voltage power lines spanning long distances.provide energy storage in the form of pumped hydro energy storage (PHES) and batteries, coupled with demand management.About 4.5 Gigawatts of new PV and wind will be installed in Australia in 2018, compared with peak demand of 35 Gigawatts.Īlthough PV and wind are variable energy resources that depend on the local weather, the approaches to support them to achieve a reliable 100% renewable electricity grid are straightforward: PV and wind are replacing old coal power stations as these are retired. In Australia, effectively all new generation capacity is PV and wind, and no new coal power stations are ever likely to be built. The Australian and Indonesian electricity systems are of similar size. PV (and wind) are now economically competitive with new-build coal and gas in Indonesia.

Although Indonesia has only a small amount of PV at present, exponential growth can change this quickly-as happened in Australia, China and many other countries.įigure 1: Net new generation capacity installed worldwide in 2017. About half of the panels would be on the roofs of buildings. Much less than 1% of Indonesian land would be required to produce all of the nation's electricity using PV. Indonesia has large solar potential because of its tropical location. 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. Gas and coal are in third and fourth spots respectively. Solar photovoltaics (PV) and wind are now the leading electricity generation technologies being installed worldwide each year. 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. Pumped hydro energy storage is a technique to store energy produced by electricity generation.
