Power Plant EPC in Indonesia — Biomass, Gas and Captive Power

Indonesia combines very large agricultural residue volumes with a grid that still leaves significant areas under-served. For palm oil mills, sawmills and agro-industrial estates, a captive or IPP biomass plant is often the most economic source of firm power available.

The constraint is rarely technical. It is regulatory: local content requirements, the permitting sequence, and the terms under which power can be sold to PLN. Projects that skip this analysis at the feasibility stage frequently reach financial close two years later than planned.

Local content (TKDN) and what it means for your equipment

Power plant equipment supplied into Indonesian projects is generally subject to local content assessment. The required percentage and the applicable calculation method should be verified against the current regulation for your project category before equipment selection, because it directly affects which components can be imported and how the package is structured. We plan the equipment split at the enquiry stage rather than discovering the problem at customs.

Permitting and grid connection

The sequence typically runs through regional spatial approval, environmental approval, and a grid connection application to PLN, with the power purchase arrangement following. Timelines vary by region. Our advice is to run the environmental and grid studies in parallel from day one, and to fix the interconnection point before ordering long-lead equipment.

Fuel: the real determinant of project economics

Palm oil mills generating from EFB, fibre and shell have a structural advantage because the fuel is already on site. Projects that rely on purchased residue from third parties carry a fuel price and logistics risk that must be modelled honestly across a full season, not a single month.

Logistics and site delivery

Most equipment enters through Tanjung Priok (Jakarta), Tanjung Perak (Surabaya) or Belawan (Medan). Oversized items such as boiler drums and turbine rotors require route surveys, particularly for sites in Sumatra and Kalimantan where road bridges constrain load. We include the route survey in the project schedule rather than treating it as a detail.
