Prabowo promises 100 gigawatts of solar power in three years

President Prabowo Subianto launched a program on Tuesday to build 100 gigawatts of solar power capacity within three years. Nikkei Asia puts the estimated cost at about $73 billion. A gigawatt is a measure of how much electricity a plant can produce at once, and the number that gives this announcement its shape is the starting point: Indonesia has 1.5 gigawatts of solar installed today, so the plan is close to seventy times that, in three years.

The reason given is money as much as climate. Indonesia buys a large share of its fuel from abroad and pays for it in dollars, so a rising import bill drains foreign currency and adds pressure on the rupiah. Power made from sunlight at home does not carry that cost. Prabowo's government frames the program as a way to lean less on fossil fuels and to keep more of the energy spending inside the country. Vietnam and the Philippines are pushing their own solar and nuclear plans, so Jakarta is not moving alone in the region.

What the announcement did not settle is who pays. Nikkei's report does not spell out how the $73 billion would be financed, which is the part that decides whether this becomes power lines and panels or another line in a speech. Indonesia has a long run of large announcements behind it this year, so analysts abroad will wait for the tender documents before they move their forecasts.

Why it matters

Electricity is one of the few household costs the state can actually move, so a real build-out would eventually show up in supply and in what you pay. The near-term test is not the 100 gigawatt figure but the first year: watch for actual contracts, financing partners, and how many gigawatts are connected to the grid a year from now. If the money never arrives, Indonesia keeps buying the same imported fuel, and the pressure that puts on the rupiah stays exactly where it is.
