Jawa Barat — Provincial Grid + DC + Industrial Feeders

Hydro and geothermal anchor the Java backbone here. Cirata (1.0 GW) and Saguling (700 MW) reservoirs run on the Citarum cascade; Wayang Windu, Salak, Drajat and Patuha contribute the highest geothermal share on Java. Layered on top: a 20 kV DC-feeder overlay covering the Karawang Timur, Purwakarta, Bandung edge and Cirebon clusters, plus a representative cut of major industrial intakes in Suryacipta, Indotaisei, Cimahi, Majalaya and Cirebon.

Jawa Barat System Headlines

Province-level estimates. Reserve margin reflects PLN AR 2024 surplus on Java-Bali allocated to Jabar by load. Renewable share is the highest on Java thanks to Citarum hydro plus the Bandung-Garut geothermal belt.

DC Operators & Industrial Intakes

Endpoints of the 20 kV overlay. Feed substation refers to the upstream 150 kV GI on the Jabar ring; injected intermediates (Karawang Timur, Purwakarta, Bandung Timur, Cirebon Industrial) are flagged where the base PLN dataset does not list them.

Confidence levels on individual rows: high = official filing or operator press release with explicit address, medium = operator website lists area and was geocoded to estate centroid, low = inferred from peering or sales material with placement at industrial-estate centroid. The 20 kV layer is curated for visualization, not a complete distribution map. Generation mix percentages are PLN AR 2024 estimates and may vary year-to-year with hydrology and geothermal availability.
