To develop and establish procedures and mechanisms to make electricity generated from biogas a feasible option for rural off-grid communities in the Sri Lankan dry zone
Today 1.2 million households and about 4.5 million people in Sri Lanka are still not connected to the electricity grid. To demonstrate that decentralised electrification of these communities is possible with electrical energy generated from biogas, Energy Forum has implemented this project. One of the main objectives has been to promote biogas as a mainstream off-grid energy technology in Sri Lanka.
Steps were taken to establish 12 pilot projects, which consisted of eleven Chinese type biogas units and one Small Batch Type biogas plant. To manage and operate the biogas power plants in the future, a community based organization (CBO) has been established in each village. Based on the experiences during the implementation of the 12 pilot projects, Energy Forum formulated a training manual for biogas power production. Following a 3-day training programme was run to selected potential biogas power developers. Parallel sessions have been conducted for developing financing schemes with officials of Provincial Councils and Regional Banks under the RERED project (Renewable Energy for Rural Economic Development Project). Energy Forum monitors the future performance of the pilot projects with the assistance of the Federation of Electricity Consumer Societies for another 3 years after project completion. Furthermore steps have been taken to draft biogas power standards for Sri Lanka.

Financial Issues & Management

Environmental Issues
The main environmental benefit of the biogas power plants is their low carbon emissions. It is tentatively estimated that the biogas power potential in Sri Lanka is around 300 MW. Assuming that 300 MW of fossil-based power plants are replaced with biogas-based energy, the net savings of CO2 emissions would be about 1.7 million tons per year. In this particular project the reduction was around 12,800 kg CO2 for the first year. Additional environmental benefits come from the by products of the biogas production as these can be used as fertilizer to aid crop growing, which reduces the chemical use of fertilizers. Furthermore, the biogas slurry is a pest repellent and hence can replace pesticides in agricultural use.Social Issues
The original concept was to test the establishment of community biogas power systems with community owned common animal sheds. However, this idea was not acceptable to the community as they were not willing to share a common shed for their animals as that was against their culture. To overcome this issue the Energy Forum tested possible options with individually owned animal sheds, which has also proofed to be successful.Results & Impacts
During the project 12 schemes have been established and are providing electricity to 56 households and water supply to 80 households. The energy systems satisfy all energy requirements of the households: energy for cooking, electricity and water supply. The access to modern energy services and clean water has significantly improved the living conditions in rural communities.Replicability

Lessons learned
The duration of the project was one year but future projects should plan more time to do some observations and tests prior the project so the long-term sustainability of the schemes can be better assured.Projects with same technology
