International Micro-hydro Power Training Course

September 13th - October 8th 1993

Pokhara, Nepal

A four week in-depth training on the design of micro-hydro schemes (up to 300 kilowatts) will be conducted by ITDG in Nepal in September 1993. The course will be held in the picturesque town of Pokara in the shadows of Annapurna and the Machapuchre Himalayas. This course follows in the footsteps of a similar training that ITDG undertook in Sri Lanka in 1991.

Micro-hydro is not merely a scaled-down version of large hydro schemes. The training course will emphasize the different approach that is required for micro-hydro in the ownership and management, site survey, design, installation and maintenance of the schemes and the different ways in which it can benefit the local community. Field visits will be made to a number of working schemes in the area with part of the course conducted in a Himalayan village powered from micro-hydro.

Ed note: The electric heat storage cooker which can be powered from a micro-hydro scheme was described in BP 27 and 29.



An Energy Sector Simulation

Reproduced from RERIC News, December 1991, GPO Box 2754, Bangkok, Thailand

Microcosm is an energy sector simulation model for a developing country that has been developed by Dr David J Edelman, Associate Professor of Energy Planning and Policy, Division of Energy Technology, Asian Institute of Technology, Bangkok, Thailand and Dr Donald M Manson of DRI/ McGraw-Hill in Washington, DC, USA. It was originally programmed in Applesoft-Basic for the Apple II computer in l 985. This new version of the mode, Version 2.0, has been modified and expanded by Dr Edelman.

The model can be effectively utilized for energy analysis work of short duration in relatively small, data-poor economies. It is also quite useful for quick survey use on a regional or national basis in more complex economies and assists in early identification of sectoral bottlenecks in major energy planning projects. Its other major application is in the teaching and training of energy planners and policy makers.

A user of the tool should be a knowledgeable energy analyst. Nonetheless the simulation is extremely useful in comparing different policy options or investment programmes and in suggesting various combinations of action that might be tested. The model is designed to balance the supply and demand of 24 energy products, both commercial and non-commercial, in a nine-sector economy over 25 years.

Letters to the Editor

Dear Sir For some time now we have been trying lo set up an improved stove programme in Angola which can then be disseminated in pert-urban areas of towns, which are today suffering from a dramatic overpopulation due to the rural migration caused by the war.

Amongst other things we have tried to adapt the Zambian stove "M'baula" but without success because of its low energy efficiency. However, we have not been discouraged; we are writing to you Following an article in Boiling Point (no. 26, December 1991) on technology transfer.

We are therefore hoping that it will be possible, through you, to get into contact with institutions, universities or other organisations in different countries which have experience of setting up programmes or have disseminated improved stoves.

Perhaps we can benefit from their experiences - we arc lacking that now - or even find a stove that can be accepted in Angola, after some adaptions to suit the people. In fact it is the first time (hat a programme of this type has been set up here in Angola and one of our main obstacles is no doubt the lack of knowledge and experience on this subject, even when the problems of domestic energy supplies are becoming very serious.

Yours sincerely
Felix Net
Directeur National de L'eau

We are posting copies of ITDG's Stove Manual and other useful information, but no doubt M. Net would be interested to hear from stove workers in neighbouring countries.


The third HEDON meeting was hosted by Intermediate Technology Development Group in Stratford, 22-24 January 1993. The Household Energy Development Organisations Network (HEDON) brings together leading northern household energy agencies and being a relatively new institution, HEDON functions and structure are still evolving. According to a recent draft position paper, HEDON's primary objective is to encourage the appreciation of and support for household energy programmes among decision-makers and the general public in developing and developed nations.

In addition to providing a convenient forum for exchange of information and sharing of experiences, the meeting reviewed the draft position paper that outlines HEDON's priorities in the household energy sector. The paper is expected to be ready for distribution at the next meeting of HEDON, scheduled to be held at Eindhoven University of Technology in the Netherlands on 3-5 September 1993. More information about HEDON can be obtained from Peter Watts and will be reported in future editions of Boiling Point.
