While PLN also intends to triple how much electricity it gets from renewable sources, most of the expansion in green energy will need to wait until the early 2030s as the utility struggles to first meet soaring demand for electricity. Indonesia’s grid is, for now, unable to accommodate on-again-off-again renewable energy, the company has said. The question for PLN is “how can renewables, which are indeed variable, and fossil fuel-based power plants be sewn together?” Darmawan Prasodjo, PLN’s president director, told a parliamentary commission last month ahead of the release of the supply blueprint. PLN unveiled a slide presentation of its RUPTL late last month, foreshadowing a massive buildout of solar and other renewable energy over the next 10 years.

Renewables will comprise a slightly smaller share of the planned expansion until the end of this decade.
