Mini-grid Webinar Series

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)¹ 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. 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:

• facilitating exchange among field practitioners, regional and international experts
  
• creating awareness on up-to-date developments, barriers and opportunities.
  

[1] In this context, micro hydropower refers to  <100kW, and mini hydropower refers to 100 - 1000 kW (or 1MW).

1st Webinar: Technology Differentiation

Webinar: Why mini-grid technologies -- PV, biomass, diesel, micro/mini hydro, wind, and hybrid systems -- need to be differentiated.

Webinar Recording

“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 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 -- Grid Interconnection (June 2017) and Productive End Use (July 2017).

2nd Webinar: Grid-Interconnection

Webinar: Grid interconnection of micro/mini hydro mini-grids: What happens when the national grid arrives?

Webinar Recording

Grid Interconnection - Introduction and summary		Grid Interconnection - Indonesia (a better version will be uploaded soon)		Grid Interconnection - Sri Lanka

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 depends on a number of parameters. Micro and mini hydropower systems which in general provide inexpensive renewable energy 24-hours a day can benefit from the grid’s ability to absorb electricity even at times of the day (or night) when local loads are low.

This second webinar in the series will present examples from Indonesia and Sri Lanka where micro and mini hydropower (MHP) systems have been successfully connected to the national grid and even benefited the local community. Country experts will describe how micro and mini hydropower developed in their country and what happened when the grid arrived. They will also explain the current conditions for grid interconnection (e.g. feed-in tariff, technical requirements and economic aspects) as well as the consequential opportunities and challenges for MHP owners.

Particularly in south and southeast Asian countries where national grids are extended not always in a “predictable” way, grid interconnection of MHP systems has emerged as an important topic, ruled by the following aspects:

• options for net metering, level of feed-in tariffs (FiT’s) and other policies and regulatory frameworks that support grid interconnection of decentralised renewables.
• clarity about ownership of the MHP system - especially for subsidised systems - and thus clarity about WHO benefits from the additional revenues.
• optional change of tariff systems for consumers on the (former) mini-grid.
• Possibility to still operate the mini-grid in an isolated mode in case of outages in the big grid.

Additional positive aspects can be: continuous stabilization of the national grid through decentralised energy production, increased domestic renewable energy production and lower carbon footprints.

3rd Webinar: Productive End Use

Webinar: Productive End Use -- Three examples of how to make it happen.

Date: Early July

Time: Forthcoming

Registration link: Forthcoming

Once implemented mini-grids need to be financially sustainable. Their operation and maintenance costs 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”.
