Despite solar being an ideal solution for energy access in off-grid
communities, the common deployment models of solar lanterns and
small home systems have not quite achieved the type of scale seen
in the grid-tied sector. Mini-grids and micro-grids are promising
deployment models for scale as they serve a much higher number of
customers per installation. Beginning in 2013, Gham Power initiated
a number of pilot projects in Nepal to test the feasibility of this model.
These experiences led to a focus on two specific configurations– a
micro-grid model to power entire villages or communities of 100 or
more households each, with majority of the load coming from anchor
tenants; and a nano-grid model for communities of 20-30 households
in a cluster, powering only predefined direct current (DC) loads. These
projects have large environmental gains. The project’s three micro-grids,
for example, replaces 4546KL of potential diesel and kerosene usage,
curbing 41 tons of CO2 emissions per year. Since individual micro-grid
sizes are still relatively small, project aggregation is a must in order
to bring institutional investment to these projects. To achieve this,
the authors call for the provision of open standards-based tools and
templates from off-grid project development.
