the photovoltaic and wind power Hybrid Project in Indonesia
The project called the "Oeledo Project" started in 1997, and was completed in 2000. Oeledo itself is a village located in Pantai Baru District, Rote-Ndao Regency on Rote Island, East Nusa Tenggara (NTT). From Kupang, the city of NTT Province, Rote can be reached in about four hours by ferry via the Pantai Besar pier. The distance from this port to Oeledo is about 22 kilometers, but it can be reached by a 1.5 hour road trip because the road is dirt and damaged. This project was officially submitted to the Oeledo community in 2001. The Oeledo project consists of socio-economic, financial and technical studies, management capabilities of rural electrification schemes using a hybrid system and participating in community development steps. The project was designed and implemented by the e-7 Network of Expertise, an international organization consisting of nine leading power companies from the G7 countries (Canada, France, Germany, Italy, Japan, UK and the United States), in collaboration with the Government Indonesia and local non-government organizations. The hybrid system supplies 127 customers with 220 Volt AC power. Wind energy and photovoltaic generate electricity which is stored in batteries and supplied to consumers for 24 hours. Wind energy consumption is measured and paid on a base month to the Village Electricity Manager (PLD), who provides and ensures proper electricity service to customers. Before the Oeledo project, ordinary people used kerosene, candles and batteries to meet their electricity needs at a cost of around Rp. 10,000 to Rp. 20,000 per month. Whereas by using renewable energy technology, with a rate of IDR 800.00 / kWh and a specified capacity cost of IDR 5,000.00 (10,000.00) per 0.5 (1) A per month (circuit breaker) promoted by PLD, it is acceptable. by the community and set forth in the service agreement between the customer and the PLD. Apart from lighting and TV / radio applications, small-scale businesses have been built in Oeledo with the aim of sustaining electricity supply, such as lighting for kiosks, refrigerators, making handicrafts (sewing, wood carving, etc.), the process of making sugar and support the activities of women's groups in Oeledo. Measures of CO 2 emissions, avoided in the project, were estimated and documented since 2001. and compared with the baseline scenario. The amount and quality of estimated data makes it possible to calculate accurately and in detail about emission reductions. The average CO 2 emission of a diesel power plant is 1.1 kg CO 2 / kWh, the project survey shows that households in remote areas generate an average of 360 kg CO 2 / year in an area. The Oeledo hybrid system can supply community needs of 22,000 kWh per year and tends to increase. This amount of energy results in an avoided emissions of around 24t CO 2 / year. The maximum possible capacity is 44,000 kWh per year, sufficient for future service expansion and changing consumption patterns. The Oeledo hybrid system consists of 22 kWp from the photovoltaic system, 10 kW from the generator generated by wind energy, 20 kW from the diesel generator as a backup, a battery storage capacity of 144 kWh and a 2x20 kW IGBT inverter. The supply of the system is limited, but feasible, to be used to power 120 households, schools, and public places through an additional LV distribution network about 3 km away. The project life of the Oeledo hybrid system is limited by technical factors. The system components have a service life of 10-20 years. The fees collected from electricity customers saved in bank accounts can be sufficient to replace most components over a 15-20 year period. Economic analysis shows that 10-20% of investment can be returned within 20 years, including maintenance costs, management fees and replacement of components after their useful life.
With this project, the people of Oeledo and the state will receive many benefits, including:
• Improve information and communication • Extend productive time for the community • Improve education due to the extension of study time until evening • Improve access to information via TV and radio • In general, from a health perspective, the system creates a cleaner
environment, reduces the risk of fire, reduces toxic pollution at home due to smoke from kerosene combustion, reduces acute lung infections, and reduces cleaning of equipment - household appliances, bed covers and mosquito net which will reduce the cost of maintaining the house. • Opening new job opportunities and small scale businesses • Creating awareness to use renewable energy technologies • Increasing the electrification ratio in rural areas of Indonesia.
