Situated in a lush, green area surrounded by rice fields, the solar farm, funded by Sumitomo Mitsui Banking Corporation, Societe Generale and Standard Chartered, consists of 340,000 panels.
At 192 megawatt peak (MWp), the farm currently generates enough power to supply electricity for the Cirata area.
Widodo said the project would be expanded to 500 MWp, while PLN said it could eventually generate as much as 1,000 MWp.
It is also attempting to reach net-zero power sector emissions by 2050 in return for financing for its US$20 billion Just Energy Transition Partnership (JETP) plan.
Under the plan, Jakarta has pledged to cut its power sector carbon emissions to a peak of 250 million metric tonnes by 2030, down from a previous cap of 290 million.
“We hope there will be more renewable energy built in our country such as solar, hydropower, geothermal and wind,” Widodo said.
