On April 7th, eleven micro hydropower professionals from six countries of South and Southeast Asia will be convening in Malaysia to participate in an ELC training workshop hosted by HPNET members Green Empowerment and Tonibung, funded by the WISIONS SEPS.
​
Electronic load controllers (ELCs) can be a vital component of micro hydropower systems. Without ELCs or other load management solutions, the electricity generated could veer outside of standard specifications, which may cause damage to appliances and system components, or become fire and electrical hazards in worst case scenarios.  However, it is often the least understood component of micro hydro systems by local practitioners, and hence can lead to long periods of downtime and high costs, when in need of troubleshooting, repair, or replacement.

The workshop aims to facilitate knowledge transfer of an Open Source ELC design to the participants. This design has been produced through collaborative project work supported by Engineers Without Borders-UK, their local partners Sibat (Philippines) and Tonibung (Malaysia). Work was continued by Green Empowerment and WISIONS, bringing about this event where the technology can be disseminated, reviewed and improved by other practitioners in HPNET.
​
The training will last two weeks, covering topics such as digital electronics, system topologies, troubleshooting and build sessions to improve practical electronics skills. The exchange activities will be done in Tonibung’s Center for Renewable Energy and Appropriate Technology. At the end of the training, participants are expected to have built their own digital ELC main circuit boards, have a good understanding of its operation, and have the skills required for installation, maintenance and repair of the system. They will be able to bring the knowledge gained back to their home organizations along with notes and resources, enabling them to share it with partners, and apply it to their projects for the advancement of sustainable development in their respective countries.

The exchange will explore how to further advance the Open Source ELC to include features for interconnection to the main grid and project-to-project interconnection, as well as improved load management.  The exchange builds onto the local momentum generated by participants of HPNET's 2016 regional training, "Capacity Building for Electronic Load Controller Technicians in S/SE Asia", supported by the WISIONS SEPS.

In partnership with the WISIONS of Sustainability Initiative and Energypedia, we are conducting a 4-part, quarterly webinar series on hydro mini-grids -- starting this month.   Join us!  Details below.

Renewable energy mini-grids are a cost-effective and reliable solution for energy access. Within the technologies available for mini-grids, micro/mini hydropower (MHP) has added advantages. It's techno-economic characteristics, such lower levelized cost of electricity, per kilowatt cost, and no need for battery storage, make it economically viable for grid interconnection and productive end use applications.

​Because MHP hardware can be manufactured locally and maintained by local actors, MHP development imparts local skills and jobs, which can evolve into local MHP enterprises. In addition, MHP strengthens catchment area and watershed protection, in turn increasing the climate resilience of vulnerable communities in hilly regions.

The number of hydro mini-grids in rural areas of Asia, Africa, and Latin America far exceed other types of mini-grids. As a proven technology with an extensive track record, micro and mini hydropower is the focus in this mini-grid webinar series. The objective of the series is to facilitate exchange among diverse actors advancing small-scale hydro, and promote approaches that lead to long-term success and optimal local benefits. Each of the four webinars will respectively provide insight on MHP reliability, sustainability, financing, and planning for scalability.

MINI-GRID RELIABILITY:  THE ROLE OF TRAINING CENTERS FOR MICRO/MINI HYDROPOWER
Watch here:​

Things progress quickly at Tonibung, and by March 2015, we had a site selected for crossflow implementation in a remote Murut village of the Bornean interior called Saliku. Pulling once again from HPNET’s wealth of knowledge and resources, we contacted a legendary (and prominently open source) turbine designer, Owen Schumacher, whose 20+ years working in Afghanistan yielded the implementation of hundreds of community micro hydro sites. Owen graciously afforded us personal, in-depth design guidance, recommending a crossflow design branded the “Traditional Mill Turbine”, or TMT, by his organization, Remote HydroLight.

Fabrication of Tonibung’s first crossflow turbine for real-world application began with the TMT-100 (so named for its 100mm effective width) in late April 2015 and continues to this time of writing, with fabrication expected to be completed by July 2015. You can stay informed about CREATE’s crossflow fabrication, and all other Tonibung activites, on their Facebook page. The open source nature of Owen’s simple TMT design allows for, and necessarily encourages, modification by workshop technicians around the world according to their local context and conditions. A complete list of Remote HydroLight’s open source turbine offerings can be found here, and their contribution to the field of open source Electronic Load Controllers (ELCs) can be found here.

Certainly, there is not enough space in a single blog post to identify all, or even most, of the influencers who have blazed the trail for me to pursue community micro hydro, but suffice it to say that my experience and good fortune has depended principally on the kindness of mentors, peers, and role models to help me find each new rung of the ladder. If one thing is certain, Laurent’s assurance to me lo those 5 years ago still holds as true today as it ever did. “All are welcome in this field -- the technology is built for everyone. There are many people who will guide you along the way, if only you show the dedication.”

On Feb. 2-6, 2015, HPNET's 2nd Annual Gathering of Micro Hydro Practitioners was  held at the ASEAN Hydropower Competence Centre (HYCOM), supported by WISIONS of Sustainability, and coordinated by Janathakshan, PT Entec Indonesia, Bandung Hydro Association (AHB), EnDev Indonesia, and IBEKA. HYCOM is a knowledge centre, offering training as well as facilitating research and development for micro, mini, and small hydropower sectors. In addition to a variety of targeted training activities, HYCOM supports the hydro industry in developing, testing, and improving their product at the national, regional, and international level.

HPNET consists of practitioners with various backgrounds from public sector, private companies, and grassroots organisations.The gathering was attended by 34 practitioners from 11 countries (Afghanistan, Bangladesh, India, Indonesia, Myanmar, Malaysia, Nepal, Pakistan, Philippines, Sri Lanka, and Thailand), making it one of the most international and diverse MHP-dedicated gatherings in Indonesia in many years. Site visits to mhp installations and electromechanical component manufacturers allowed participants to see closely how the industry has grown in Indonesia. These visits also served to excite participants’ ambitions in their home countries.

As part of the agenda, intense discussion sessions were organized to refresh the Network’s vision and working plan for the coming year and beyond. Technology transfer, knowledge sharing, and policy advising remain some of the main focus areas adopted by HPNET, but the importance of community involvement and local capacity building received special emphasis.

HPNET emphasizes overall sustainability by putting community empowerment as the core, ultimate goal. Forest and water conservation, productive use of energy, as well as technology innovation also will be strongly pursued by the Network, which has agreed that joint collaborations on transnational MHP initiatives are a vital mechanism to maintain and enhance the momentum of MHP development.

Gerhard Fischer, the holistic expert behind HYCOM, with over 30 years of experience in MHP development, thought the event to be very beneficial for all participants: “I am quite convinced that for these small power plants – maybe up to 100kW – the knowhow should be there where the site is. It should be accessible for the villages. That’s why the success of these things in Nepal, Indonesia, and other countries like Pakistan is connected with the local fabrication of the equipment. We need networking. Each country has its own development. To look what is working where and to coordinate this knowhow and to make it available is a very important thing.”

Fischer went on to explain the value of HPNET in linking institutions with similar targets. “We should work together,” Fischer added, “and also take seriously into account what others have done to develop the technology.”
