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. Author providedīecause of its equatorial location solar energy does not vary much throughout the year, unlike in higher latitudes. 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.
