Biomass Power Generation Project in the State-owned Palm Oil Mills”
Sub-titleBiomass Power Generation Project in Sei MangkeiSpecial Economic Zone(SEZ), North Sumatra(Studies for Project Development and Organization )
The target of study is to plan the introduction of Indonesia’s first small CFB (circulating fluidized bed) boiler technology and torealize commercial biomass power generation.
“Biomass Power Generation Project in Indonesian State-owned Palm Oil Mills” (Studies for Project Development and Organization ) Company proposed: Shimizu Corporation
(1) Planning of overall facilities and evaluation of project profitability
(2) Study of project scheme, project plan and risk countermeasures
(3) Preparation of MRV methodology and review of methodology applicability
(4) Environmental impact and stakeholders’ comments
(5) Discussions with related agencies

EFB (empty fruit bunch) is an unused biomass resource in palm oil mills. It will be collected and utilized to generate power, which is supplied to industrial estates. As a result, the ratio of biomass used in domestic primary energy will be enhanced and this will contribute to NAMAs.
Purchased power Reduetion
of CO2 emissions
Current situation
CO2 emissions
- Power is supplied from the grid or generated by fossil fuels at the industrial estates.
- EFB is returned to palm fields close to the palm oil mill.
- Since part of the purchased power is substituted by power generated from biomass, emissions of CO2 derived from fuel at grid power stations is reduced.
- Auxiliary fuel for boiler and fuel for transportation of biomass are the project emissions.

Small CFB boiler power generation system: 12 MW
This Japanese low-carbon technology, which is unprecedented in the world, utilizes a compact (6 MW per boiler) fluidized bed (CFB) boiler for generating power from biomass. This has been developed for efficient power generation based on stably combusting EFB (empty fruit bunch of palm), which is fuel comprising high water content (50%) and large size (around 30 cm). The technology has undergone continuous combustion testing on the pilot level and is at the point where it can stand up to commercial operation. Conventionally, fibers and shells comprising low water content (20~30%) and small size (no more than a few centimeters) were used in small private generation stokers in mills, however, such equipment sometimes cannot be used with EFB because much of the fuel is not combusted and it is necessary to make frequent maintenance stoppages. The abovementioned CFB boiler has been packaged and its costs have been cut until it is now deemed to be internationally competitive in general assessments of technology, price and environment. The area around Medan in North Sumatra has been selected as the project site because it offers excellent road conditions and a high concentration of palm mills that will make it possible to achieve the cheap and stable transportation of fuel. Moreover, through conducting a joint project with a state-owned plantation corporation, it is intended to remove barriers to the biomass power generation business and realize stable commercial operation.

Planning of overall facilities and
evaluation of project profitability
Project site: Sei Mangkei Special Economic Zone , Industrial Estate・Designated under the Indonesia Economic Development Acceleration and Expansion
Plan (MP3EI) ・The first phase zone of 104 ha, out of the overall estate area of 2,002 ha, is under
construction. ・3.8 ha is planned as a biomass power plant area
Power : Sold to the industrial estate management company
Fuel (EFB):Colleced from 5 nearby mills (250,000~300,000t/y)
・Pay back period : 7.1 years (without Carbon Credit )6.2 years(with Carbon Credit )
Issues in project actualization・JCM capacity building ・Support from the governments of Japan and Indonesia
MRV・Focused only on green field projects ・Simplified the calculation of fuel consumption for
transportation ・Used the methodology format for domestic
emissions trading
Expected reduction in emissions: 57,500t-CO2/year
Finance:Own funding + other company funding + Government of Japan aid system
BOT system is to be proposed
• All Fiber and a part of Shell are utilized for power and steam at almost all the POMs(Palm Oil Mills) by stoker type boiler, and EFB is returned to Palm plantation by its high water contents
• Composting projects and waste-to-energy projects for EFB with Shell have been commenced in a few POMs, but EFB(100%)-CFB Boiler is not introduced
Reference Scenario : BAU
Project Activities• EFB will be collected from several POMs to one site, and then CFB Boiler
Plant will supply power to SEZ Sei Mangkei• Emission Reduction(ER) of the Project is calculated by following
(the reduction of fossil fuel in the Grid system) - (fuel use for EFB transportation)
