Indonesia has all of the photo voltaic power and pumped-hydro power storage potential wanted to develop into a photo voltaic big by mid-century. At present developments, Indonesia would be the fourth largest producer of photo voltaic power by 2050.
A future financial and photo voltaic big
By the center of the century, Indonesia is anticipated to develop into the sixth most populous nation on this planet with 320 million folks. It is anticipated to develop into the highest 4 world economies by gross home product (after China, India and the US), from 16th spot at the moment. What occurs in Indonesia’s power markets is vital on a world stage when it comes to financial influence and greenhouse gasoline emissions.
Currently, Indonesia depends closely on fossil fuels for power and is a serious fossil gasoline exporter. Indonesia’s electrical energy consumption is beneath world requirements at about 1.1 MWh per particular person per 12 months. This compares to 6-12 MWh per particular person per 12 months in developed international locations such because the US, Europe, China, Singapore and Australia, and 2-5 MWh per particular person per 12 months in superior rising economies reminiscent of Brazil, Chile, Mexico and South Africa. Indonesia’s electrical energy consumption is more likely to improve considerably by mid-century on account of growing affluence, inhabitants development and electrification of transportation, heating/cooling and business. Using clear electrical energy to “electrify every little thing” permits for the entire decarbonization of an financial system.
Many regulatory and financial indicators level to the speedy shift away from fossil fuels as a supply of newly established electrical energy technology in Indonesia. The nation has comparatively poor wind power assets on account of its location on the equator. However, Indonesia’s photo voltaic assets are large. Importantly, the equatorial local weather implies that the demand and availability of daylight varies little from week to week, eliminating the necessity for seasonal storage.
If we assume that Indonesia’s electrical energy consumption will improve to 10 MWh per particular person per 12 months (much like developed economies at the moment) on account of elevated abundance, after which double to twenty MWh per particular person per 12 months to accommodate “electrification of every little thing,” then Indonesia will want about 6,400 TWh of electrical energy per 12 months by the center of the century. This could be in comparison with the present world electrical energy consumption of about 30,000 TWh per 12 months.
By 2023, there might be twice as a lot photo voltaic capability deployed worldwide than everybody else mixed. This is compelling market-based proof that photo voltaic power gives the most affordable electrical energy at the moment. A wealthy and decarbonized Indonesia by mid-century would require the deployment of about 5,000 GW of photo voltaic panels (15% capability issue). Assuming 25% environment friendly photo voltaic panels, the required space of photo voltaic panels is 20,000 km.2or 60 m2 (15 kW) per particular person.
Where can photo voltaic panels be positioned?
Indonesia is an equatorial archipelago with a excessive inhabitants density. Fortunately, Indonesia has limitless potentialities for the deployment of photo voltaic panels with low battle with environmental values.
Roofs can accommodate many photo voltaic panels, particularly within the early years of photo voltaic deployment. Abandoned coal mines can accommodate about 500 GW. Solar set up mixed with agriculture can accommodate 1000-4000 GW. However, the largest alternative is the photo voltaic panels floating within the calm, equatorial, ocean waters of Indonesia. In reality, Indonesia can harvest 500,000 TWh of photo voltaic power from maritime areas that haven’t skilled winds stronger than 15 m/s and waves larger than 6 m prior to now 40 years, which is 16 occasions larger than the present world electrical energy consumption.
100% photo voltaic power in Indonesia
Storage is required to help photo voltaic power in a single day and longer. Batteries can present economical power storage for a number of hours. However, Pumped Hydro Energy Storage (PHES) strongly prevails for large-scale power storage as a result of it’s cheaper. For instance, the Snowy 2.0 pumped hydro system in-built Australia gives 350 GWh of storage (2.2 GW of energy) at a value of $23/kWh, which is about one-tenth the price of comparable battery storage. In follow, a mix of latest and second-life batteries (excessive energy for brief durations) and PHES (low-cost long-term storage) is most popular.
Indonesia has limitless entry to premium high quality PHES websites within the vary of 5-5000 GWh. For comparability, 5000 GWh is equal to the batteries of 70 million electrical automobiles. Hundreds of Indonesian websites within the Global Pumped Hydro Atlas are very distinctive, with giant heads (altitude distinction between two reservoirs) of 600-1600 meters, brief strain tunnels connecting the reservoirs, and low-cost reservoir that requires the motion of small volumes of rock to dam giant volumes of water. Overnight storage is a solved downside.
Recently, a high-resolution evaluation of a 100% solar energy grid for Indonesia was carried out, together with hourly matching of a decade of demand, photo voltaic power provide, storage and transport. The all-in levelized value of wholesale electrical energy is estimated at $77-102/MWh, which is absolutely aggressive with different fossil fuels. Interestingly, the modeling reveals that connecting the entire of Indonesia by way of excessive voltage submarine cables isn’t any higher than every of the 5 principal areas “alone”. This is in contrast to the expertise of nations at greater latitudes the place giant space interconnection strongly reduces storage necessities by smoothing native climate and demand. In equatorial Indonesia, the climate all over the place is similar on a regular basis, and that is additionally the case in lots of different sunbelt international locations.
There isn’t any want to instantly shut Indonesia’s current coal-fired energy stations, as they generate a small fraction of world greenhouse gasoline emissions. The key to efficient decarbonization is to cease shopping for new fossil gasoline machines, together with energy stations, vehicles and industrial furnaces. Current gear will largely be retired within the subsequent 20 years, to get replaced by electrical variations pushed by clear photo voltaic power.
