Demand side management for rural Nepal

Nepal has a long history in rural electrification, particularly through the efforts of a mature microhydro industry. However, in recent years, there has been a slowdown in the number of plants being installed throughout the country. The general conclusions that have been reached include:

* micro hydro plants (MHPs) that have only lighting as an end use are not financially sustainable, particularly in the more remote districts
* ongoing technical support is crucial for sustainability;
* training for developing technical and managerial skills is important;
* not all systems have been been properly designed

Many of these problems result from a focus on the supply of power without analysing the demand. The willingness to pay for MHP systems varies throughout the country, from 15 NRs/month in the most remote and poor districts to about 200 NRs/month in the richer districts. Although these figures are approximate, at a capital investment of about 14,000 NRs (US$200) per household, it is clear that it will take many, many months to recover the initial investment if there are no other income-generating end uses for the MHP.

One solution is to reduce household power consumption, allowing the power generated to be shared among more households. Several innovative projects are now under way which focus on this approach.

Title in French
Gestion de la demande pour le milieu rural népalais.
Abstract in French
La plupart des problèmes liés a l’électrification rurale au Népal sont dûs a l’absence d’évaluation de la demande. La capacité à payer pour l’installation des micro-centrales dépend du revenu. Une solution pour abaisser les coûts serait de diminuer l’énergie allouée aux foyers par l’introduction de lampes compactes fluorescentes ainsi que des chargeurs de batteries. Un nouveau point d’entrée pour l’éclairage en milieu rural est les diodes émetteurs de lumière (White Light Emitting Diodes) qui procurent suffisamment de lumière pour la lecture. Dans quelques zones, des technologies utilisant des pédales mues par la force humaine peuvent produire suffisamment d’énergie pour alimenter des lampes. En moyenne, il faut pédaler 30 minutes pour recharger une batterie qui peut fournir 4 heures d’électricité.
