Jawa Tengah + DIY Provincial Grid + Industrial Intakes

Anchored by Tanjung Jati B (2.64 GW coal) on the north coast and Cilacap (1.4 GW) on the south, with the Mrica cascade and Dieng geothermal lifting the renewable mix to ~17% — the highest on the Java backbone.
This sub-page adds the 20 kV industrial-feeder overlay to the 500/150 kV provincial map and single-line diagram for Jawa Tengah and DIY.

DC Operators & Industrial Intakes · 20 kV Feeder Detail

Operator-level detail of the 20 kV feeder overlay. Capacity expressed as IT load (MW) for DC sites and aggregate intake (MW) for industrial estates. Confidence reflects how directly the address is sourced (high → press release / regulatory; medium → operator website; low → estate centroid).

Provincial Anchors

500 kV substations and major power plants drawn from the provincial filter of the base data file. Tanjung Jati B (Jepara) is the largest single coal asset on Java; Mrica + Dieng anchor the renewable mix.

        Footnote: Tanjung Jati B (Jepara) injects directly into the 500 kV Tanjung Jati - Ungaran corridor and is co-fired with biomass under the PLN co-firing programme; the renewable share reflects that mix plus Mrica cascade hydro and the Dieng geothermal field. Industrial intakes shown for Kendal SEZ, Batang KITB, Semarang, and Cilacap are sourced from PLN UID Jateng + DIY feeder maps where the overlay file is unavailable; capacities default to the estate centroid until the parallel overlay file lands.
