WISIONS of Sustainability
The main objective of WISIONS is to make clean energy a default solution for basic energy needs in developing regions, by helping local partners to identify successes and bring them to scale through regional networks, marketing and demonstration.

Grid-Connected Biomass Gasification in Sri Lanka
News from WISIONS posted on April 12th, 2017
A 20 kW power pellet (wood) gasifier and engine was purchased, together with an induction generator. The team designed and manufactured a suitable woodcutter and constructed a power house. Subsequently, they signed the "Standardised Power Purchase Agreement" with the Ceylon Electricity Board, which permits the energy produced to be sold to the grid. As a last step, the power plant was connected to the national grid. To ensure sustainability, a wood supply chain was established with the farmers, plant operators were trained and a 20 year power purchase agreement was signed.
Monitoring of the plant’s performance is still on-going. For more general information on this SEPS project, please visit our project page: Introducing grid-connected biomass gasification units for rural energy access and community development.
Handbook on Biogas Integration into Sustainable Farming Systems
News from WISIONS posted on January 9th, 2017
Biogas generation through the anaerobic digestion of biomass has been carried out successfully in India and other parts of the world for decades. In this SEPS project, biogas was produced mainly from banana stem-waste at small rural banana plantations and then distributed to more than 70 households in the village of Gundigere for cooking purposes. The project has demonstrated that a biogas system can be based solely on stem waste from banana plantations, although the methane generation potential of these parts of the plant is much lower than that of fruit and peel.
IEI’s in-depth handbook offers potential users information on:
- Integrated banana cultivation, biogas generation and stove-fuel delivery
- Operation at family/community/village level rather than industrial scale
- Actual implementation and operation in India
- Background information on technologies and resources
Enhancing Productive Biogas Use in Mexico
News from WISIONS posted on February 4th, 2016
In the second phase, the project aimed to demonstrate the feasibility of adapting and applying commercial gasoline motors available in the Mexican market in order to provide mechanical and/or electric power to small and medium farmers by using their biogas. In this phase, there were five significant areas of work: biogas filtration, matching energy production and use, motor sizing and design, grid interconnection, and training and maintenance. Sixteen motors have been adapted and installed by IRRI.
The project has already led to significant advances in the application of biogas for small scale electric power (between 5 and 10 kW) and has opened the door to the further development of the technology. All the installed motors are currently under a monitoring and maintenance regime for the next 12 months to improve data on the operating parameters and benefits of these systems.
