Small wind turbine construction workshop at Khwopa College of Engineering

Organized jointly by: Khwopa College of Engineering

Workshop conducted by: KAPEG and ACE

The workshop is scheduled from July 10th to July 17th, 2019.

Workshop Overview

The general aim of the construction workshop is to provide a simple and accessible way to enhance the ability and research capacity of students/faculties in universities in the field of small wind turbines (SWT) by being able to develop and reconfigure machines with the locally available materials.

The wind turbines built in the workshops are based on the designs of Hugh Piggott, a renewable energy expert living in the off-grid community of Scoraig (Scotland), as described in his ‘Wind Turbine Recipe Book’. These wind turbines can be constructed with the use of common materials, simple manufacturing techniques, and basic tools, providing a low-cost small wind turbine that anyone can build. Hundreds of homemade small wind turbines have been constructed worldwide using these designs, and have proven to be robust, efficient, easy to maintain and quick to repair. Typical applications of locally manufactured small wind turbines are development projects such as electrification of village communities, educational projects in universities and schools and sustainability projects such as renewable energy electrification of eco-villages.

Locally manufactured small wind turbines have been installed in various regions of Nepal in the past with initiatives taken by different INGO’s/NGO’s and companies. Various technical issues with the installed small wind turbines have been observed in the past by KAPEG in terms of design and construction malpractice. Therefore, the construction workshop is an approach taken by Kathmandu Alternative Power and Energy Group (KAPEG) in support with Khwopa College of Engineering (KCE) in order to strengthen the knowledge and capacity of students and faculties in the academic institutions.
