5 5-1. e7 Climate Change Projects Institutional Barriers & Lessons Learned Management Systems Creation of local utilities (PLDs) Successful management schemes are the key - Focus on involvement of local people - Clear objectives for all parties - Intensive training - over time - Establishiung after-sales service contracts with - local contractors e7 Climate Change Projects Institutional Barriers & Lessons Learned Technical Training Simulations & case studies Several training sessions required After start-up, some supervision is important 10

- Establishiung after-sales service contracts with - local contractors 9 5-1.

6 5-1. e7 Climate Change Projects Institutional Barriers & Lessons Learned Sustainable Financial Scheme Socio-economic studies Focus groups, e7 assessments & NGO presence Determine ability & willingness to pay - Need maximum income to assure sustainability - Must design tariffs within reach of villagers Clear & transparent banking schemes e7 Climate Change Projects Conclusions e7 s Indonesia project is one example - not finished yet! How renewable energy can work in remote areas Most important aspects: - Management schemes - Financial schemes - Training (technical and management) 12

of villagers Clear & transparent banking schemes 11 5-1.

9 5-2. Renewable Energy Supply Systems What institutional barriers are perceived 1. There is no Sustainable Organization for maintaining Energy Supply System 2. Lack of Human Capability for maintaining Energy Supply System 3. Lack of Financial Scheme Renewable Energy Supply Systems Lessons learned 1.-2 Clear objective of Organization shared by all members. Each member needs his/her own objective Each member should be evaluated fairly. Needs practical skills to cope with difficult situation. These skills must be developed by case-study workshop. Financial scheme must be firmly established. 18

Lack of Financial Scheme 17 5-2. Renewable Energy Supply Systems Lessons learned 1.-2 Clear objective of Organization shared by all members.
