This week, the SIBAT and CREATech team, from Luzon, Philippines, took the initiative to complement their 25 years of micro hydro development in the northern Philippines with a learning visit to Tonibung and CREATE’s work in Sabah, Borneo Malaysia.  Tonibung has been the pioneer of community-based micro hydro systems in Malaysia for 25+ years, focusing on indigenous communities and social enterprise.  Tonibung closely collaborates with Green Empowerment.  HPNET's collective knowledge has been greatly enriched by the active membership of all  five organizations.

The SIBAT team took time to understand Tonibung’s local manufacturing developments and their approach to linking MHPs to social enterprise for scaling productive end use.

The team visited Longkogungan village and Kalanggaan village, along with Tonibung staff members Bill Baxter and Willery Larry, and Green Empowerment staff member Dan Frydman.

Here is what SIBAT engineer Ms. Benazir Bacala has to say about the recent visit:

“Visiting the sites of Tonibung made me appreciate more the work of NGOs. It was an adventure that we could never forget, risky hiking,  lots of crossing rivers...Very inspiring how Tonibung and its staff were also able to reached those villages in remote areas to provide sustainable energy to the communities and their efforts and dedication to help the people.

We learned a lot about their mhp with pelton turbines, both direct couple and belt-driven systems, that were locally manufactured at CREATE.”

Over the last year, HPNET has shed light on the key factors for sustaining hydro mini-grids over the long-term. This webinar addressed the importance of social enterprise for ensuring mini-grid sustainability, featuring practitioners who are leading the transition from grant-dependent to enterprise-based hydro mini-grids. The speakers highlighted the potential for local social enterprise to support revenue-driven and equitable hydro mini-grids. 

The webinar presented:
​

• The linkage between enterprise-based approaches and long-lived hydro mini-grids;
• Best practices to transition from grant-dependent to local social enterprise models, based on micro hydro experience in Nepal, Malaysia, and Indonesia;
• Solutions to scale their efforts to more micro hydro communities, including how to make better use of funding resources that currently go toward grant-dependent projects.

Introducing SEEED

The webinar also introduced a new HPNET initiative: Social Enterprise for Energy, Ecological, and Economic Development (SEEED). The SEEED initiative aims to support local practitioners and micro hydro communities in the transition to enterprise-based approaches.

The webinar supported an initial objective of SEEED, by identifying and highlighting the work of practitioners who are already paving the path toward long-lived mini-grids anchored in local social enterprise.
​
Stay tuned for more information on SEEED, to be released in coming weeks!

HPNET and WISIONS hosted a Deep Dive Workshop at the Asian Development Bank (ADB) Asia Clean Energy Forum (ACEF) 2019, entitled Hydro Mini-Grids in the Asia-Pacific: Scaling Inclusive
Enterprise-Based Approaches.  Special thanks to the ACEF team, our speakers, and WISIONS for making the rich dialogue possible!

Part 1 - Examples and Opportunities for Enterprise-based Hydro Mini-Grids
Moderator:  Divyam Nagpal
Panelists:  Bir Bahadur Ghale, Hydro Concern Ltd., Nepal; Satish Gautam, UNDP Renewable Energy for Rural Livelihoods, Nepal; Sandra Winarsa, Hivos Southeast Asia; Meherban Khan, Aga Khan Rural Support Programme (AKRSP) Pakistan, and Dipti Vaghela, Hydro Empowerment Network

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:​

A common cause of power outages in communities with micro hydropower systems is when the demand on the system is too high. Residents are often unaware of their energy usage leading them to connect more appliances than can be supported. This causes the safety systems to disconnect the supply, causing the shutdown.

Through collaboration between Tonibung, Green Empowerment and HPNET, and funding from the WISIONS Sustainable Energy Project Support (SEPS) grant, an open-source design for the device was conceptualized, aimed at enabling local practitioners to manufacture it themselves.

The load indicator was envisioned to be a simple plug-and-play device that can be fitted in any regular household socket. When the micro hydropower system is nearing a critical threshold, the device will sound an alarm warning consumers that further usage of appliances will overload the system and cause a power outage.

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.”
