Mini-Grids Webinar Series
Renewable energy mini-grids are a widely discussed solution for cost-effective and reliable energy access. However, within the mini-grids dialogue micro and mini hydropower (MHP) is often overlooked, despite the large number of beneficial projects operating globally, particularly in rural regions of Asia, Africa, and Latin America.
Many MHP systems originated as water mills that were upgraded to generate electricity (e.g. Afghanistan, Pakistan, and northern India). Some have transitioned from isolated mini-grids to grid-interconnected systems (e.g. Indonesia and Sri Lanka). As a proven technology with a long track record, micro/mini hydropower is the focus of this webinar series, which will also analyze similarities and differences among the various mini-grid technologies. read more
Each webinar in the series will focus on a distinct and relevant topic, namely Technology Differentiation, Grid-Interconnection, and Productive End Use.
The objectives of this webinar series are to strengthen the sector by:
a) facilitating exchange among field practitioners, regional and international experts
b) creating awareness on up-to-date developments, barriers and opportunities.
 In this context, micro hydropower refers to <100kW, and mini hydropower refers to 100 - 1000 kW (or 1MW).
1st Webinar: Technology Differentiation
1st Webinar: Why do mini-grid technologies -- PV, biomass, diesel, micro/mini hydro, wind, and hybrid systems -- need to be differentiated?
Thursday, 4 May 2017 at 2:00 p.m CEST.
“Mini-grids” have become increasingly popular in recent years because of
- The enormous cost of grid extension in rural areas as well as
- The limitations of household systems (e.g. solar home systems).
Often mini-grids based on different energy sources are simply lumped together when it comes to project and program design, calls for proposals, and in legal and regulatory frameworks. However, all mini-grids are not all the same. This webinar will highlight the important technical and non-technical features, as well as pros and cons of different technologies to create awareness on the need for differentiation of mini-grid systems.
The main objectives of the webinar are to provide:
- an impartial assessment of different RE technologies for electricity generation in mini grids based on facts and figures and experience from different countries
- an overview and framework for comparison (pros, cons, business models, ranges for specific cost per kW, generation cost per kWh, cost drivers, scalability, variability of the resource and related storage requirements etc.)
- key points to be considered when designing rural electrification programs with different RE technologies.
This webinar on mini-grid technologies is the first in a series of three webinars on mini-grids. Stay tuned for our upcoming webinars on -- Grid Interconnection (June 2017) and Productive End Use (July 2017).

2nd Webinar: Grid-Interconnection
As governments worldwide prioritize rural electrification, an increasing number of mini-grids built for rural communities are facing the “question” of what happens to the mini-grid when the national grid arrives. Whether this is a serious problem or rather a big opportunity for the community will depend on a number of parameters.
Grid interconnection of micro and mini hydropower (MHP) has emerged as an important topic in south and southeast Asia, driven by several factors:
- MHP facility owners’ need for long-term certainty in cases where the national grid is expanding into areas where isolated MHP mini-grids operate;
- Net metering, feed-in tariffs (FiT’s) and other policies and regulatory frameworks that support grid interconnected renewable energy;
- MHP’s ability to provide inexpensive renewable energy 24-hours a day, and the grid’s ability to absorb this electricity even at times of day (or night) when local loads are low;
- Country targets for increased domestic renewable energy production, lower carbon footprints, and increased electricity access.
This second webinar in the series will include
- Examples from Indonesia and Sri Lanka where micro hydropower systems have been successfully connected to the national grid and even benefited the local community.
- Country experts will describe how micro hydropower developed in their country, what happened when the grid arrived, as well as the current conditions for grid interconnection (e.g. feed-in tariff, technical requirements and economic aspects).

3rd Webinar:Productive End Use
are recovered from tariffs, which depend on power consumption. Providing only lighting is a missed opportunity to bring optimal impact to economically marginalized rural communities. Micro/mini hydropower can generate many kWh's -- we need to learn how to make use of them!
Productive End Use (PEU) of energy refers to activities that increase income or productivity in different sectors such as agriculture (e.g. irrigation, grain milling), manufacturing (e.g. carpentry, welding, and sewing), and the service sector (e.g. restaurants using electric lights, sound systems, refrigerators, mobile charging stations).
This third webinar in the series will focus on PEU of mini/micro hydropower systems. It will examine
- The social and technical pre-conditions, such as load management and technical reliability, and options such as mechanical drive for agricultural processing.
- The increase of load factor through PEU and corresponding increase of the economic viability of the system.
- Three examples of systems promoting productive end use in different countries. It will present pros and cons of electrifying "existing activities” versus “new businesses”.
