Indonesia — Renewable Energy Systems Project

Microhydro, solar, and wind power
Key Objectives:
  • To provide a reliable source of electricity to remote communities in Indonesia, through renewable energy such as solar home systems, microhydro, and solar-wind hybrid systems.
  • To contribute to sustainable rural electrification in the area, providing homes, schools, and community centres with electricity while reducing the use of traditional forms of fuel such as kerosene.
Completed in 2000

The Indonesia Renewable Energy Systems Project supplies a limited but reliable amount of electricity to households and communities in remote rural areas of Sumba, East Timor, and Sulawesi in Indonesia. Through autonomous electricity systems, owned and operated from within the villages, the renewable energy is harnessed from:

  • microhydro power 
  • solar home systems
  • wind-solar-diesel hybrid system

The rural electrification schemes provide homes, schools, and community centres with electricity while reducing the use of traditional forms of fuel such as kerosene.

Microhydro Power

The three microhydro power systems in the remote areas of Taba, Tendan Dua, and Bokin on Sulawesi Island as well as the microhydro power system at Waikelosawa on Sumba Island, were all completed and fully operational by December 2000. These systems provide electricity to roughly 2500 people through a power supply ranging from 13kW to 60kW.

Solar Home Systems

One hundred of the Partnership’s solar home systems and another 75 systems provided by the Indonesian government have been installed in two villages. The Partnership also rehabilitated 17 solar home systems in a third village. Each solar home system provides 50W to individual users, sufficient electricity for lighting, radio, and television.

Wind-Solar-Diesel Hybrid System

The Partnership also installed a solar photovoltaic-wind hybrid system with a diesel backup, as well as a distribution network on Rote Island. This facility provides electricity to more than 600 people and allows for more than three days of autonomy in case of adverse weather conditions.

The project, with a combined generation of approximately one million kWh per year, provides electricity to eight remote communities with more than 4000 people. The calculated CO2 offset resulting from this project is expected to reach more than 33,000 tonnes during its technical life.

Aside from the project’s technical merits, the focus was to develop and introduce an innovative, sustainable, and decentralised management concept for rural electrification. The team created small village-run electricity co-ops to manage the facilities and assume responsibility for their operation and maintenance. Furthermore, with the assistance of local NGOs and users’ groups, the Partnership provided a wide range of training and capacity building to enhance the local capacity of the village-run electricity co-ops, and to raise awareness among users in order to ensure the communities’ acceptance of the project. The Partnership sought to address the socio-economic intricacies of the remote and rural populations to sufficiently strengthen the local capacity in order to guarantee the long-term sustainability of the facilities. The project was monitored for two years following the completion of construction. 

At the workshop on "National Strategy Study on Clean Development Mechanism" of the State Ministry of Environment (KLH) on March 1-2, 2001 in Jakarta, the facilities were officially transferred to the Indonesian Government (Click here to view the press release). The Partnership also presented its Renewable Energy Systems in Indonesia: Lessons Learned report.

As an outstanding demonstration of sustainability and environmental achievement, the Partnership’s Indonesia project was awarded the 2002 ASEAN Energy Award in the off-grid category for the project’s Ta’ba Microhydro Power Plant at Bali’s PrepCom4 in July 2002, and the 2002 ICC/UNEP World Summit Business Award for Sustainable Development Partnerships at Johannesburg’s WSSD in September 2002 (click here to view/download Indonesia project information pamphlet).
