How Far Along Is B50 Distribution Progress Across Indonesia?
B50 Biodiesel Rollout Reaches Most Indonesian Fuel Stations
Kabarsaji.com – Indonesia’s shift to B50 biodiesel has advanced across much of the country, with roughly 94 percent of fuel stations now supplying the higher biodiesel blend. The rollout reflects the government’s transition away from B40, although a portion of the distribution network is still completing operational adjustments.
Eniya Listiani Dewi, the Energy and Mineral Resources Ministry’s director general for new and renewable energy and energy conservation, said 6,050 locations had begun B50 distribution. Another 360 sites remained in a transition stage as the nationwide fuel system moves from the previous B40 blend.
B50 is a diesel fuel mixture containing 50 percent biodiesel and 50 percent conventional diesel. Its biodiesel component is fatty acid methyl ester, or FAME, which is produced from processed vegetable oils and is central to Indonesia’s renewable-fuel program.
Terminals Continue Moving From B40 to B50
The transition is also underway at delivery terminals that supply fuel stations and other users. Of 104 delivery terminals, 76 had started handling B50, while 28 were still converting their operations from B40.
Fuel-terminal progress is further advanced within Pertamina Patra Niaga’s network. President Director Mars Ega Legowo Putra said 120 of its 121 fuel terminals were already distributing B50. The only facility yet to begin was the Sintang Terminal.
Sintang’s delayed rollout has been tied to access difficulties caused by dry-season conditions. Lower water levels have made river transport more difficult, affecting the terminal’s supply route.
This is due to weather factors. We are still having difficulty accessing the river channel at the Sintang Terminal due to the dry season, which has caused some rivers to shrink.
The situation illustrates why a nationwide fuel transition involves more than changing the blend at refineries or depots. Distribution depends on local transport links, storage systems, delivery schedules, and the ability of terminals to receive and move fuel reliably. Remote areas with river-based logistics can face different challenges from major urban markets served by road, rail, or port infrastructure.
More Than 10 Million Kiloliters Distributed
Total biodiesel distribution had reached 10.69 million kiloliters by September 2026. The figure includes 7.27 million kiloliters of B40 supplied from January through June, followed by 3.42 million kiloliters of B50 since distribution began in early July.
The changeover timetable gives distributors until September 30, 2026, to complete their transition from B40 to B50. This period allows fuel terminals, service stations, and industrial users to manage existing inventories while adapting to the new mixture.
For readers, the key practical point is that B50 availability has become widespread, but not every distribution point was fully converted at the same time. The transition period is intended to reduce disruption while the fuel supply chain standardizes the new blend across Indonesia.
FAME availability is expected to range from 16.8 million to 18 million kiloliters during 2026. Maintaining sufficient supply is important because the increased biodiesel portion in B50 requires more FAME than B40. The availability target therefore supports both routine distribution and the broader shift in blending requirements.
Testing Extends Beyond Road Vehicles
The B50 program is not limited to passenger vehicles and commercial road transport. Trials are currently taking place for trains, while testing has been completed in several other sectors. These include automotive applications, machine tools and agricultural equipment, heavy mining machinery, maritime transport, and electricity generation through generator sets.
Such testing matters because diesel-powered equipment operates under very different conditions. Mining machinery may work for long periods under heavy loads, generators need dependable fuel during extended operation, and marine engines face different storage and operating environments. Completed trials in these sectors indicate that the government has been examining B50 use across a broad range of diesel applications.
The rail trial remains a notable next step. Rail operations require consistency in fuel quality and supply because service reliability depends on regular, coordinated operations. Its ongoing status shows that the B50 transition is still being evaluated in certain uses even as distribution has expanded rapidly.
A Nationwide Transition Still Nearing Completion
Indonesia’s B50 rollout has moved from an early-July launch to distribution at thousands of locations within a few months. With most service stations and nearly all Pertamina Patra Niaga fuel terminals already participating, the program is close to full national coverage.
Remaining work is concentrated in transitional sites and locations facing logistical obstacles, including Sintang. The September 30 deadline provides the final window for the B40-to-B50 conversion, while continued FAME supply and sector-specific testing will shape how smoothly the new blend becomes part of everyday diesel use across the country.
