From the 206 Villages in the SabahRE2 Project Portfolio, consortium member TONIBUNG have now undertaken feasibility studies for 57 communities in a possible 35 mini-grids across Sabah. These locations have been selected on the basis of technical feasibility for mini-grid deployment through micro-hydro, solar or solar/hydro hybrid systems. The results showcase a portfolio of opportunities from which a selection and planning process for each mini-grid project can lead into the engineering and implementation stages. The findings of the Feasibility Studies are summarised here.
The Feasibility Studies complement the Project Portfolio by providing field data for testing technical and financial estimates and assumptions to enable basic design and costing. Generation capacity estimates are based on estimates of dry and wet season flow alongside available head in forest streams close to un-electrified communities. This video shows how engineers and communities collaborated to produce these assessments in Ranau, and here is a useful background video on how to do micro-hydro feasibility studies developed by TONIBUNG and Green Empowerment under another project with the Alliansi Masyarakat Adat Nusantara (AMAN) in Indonesia. Similarly, solar radiation potentials are investigated in the selected sites involved. Feasibility Studies seek to match calculations of current and future demand based upon the Project Portfolio data collected under Output 3 to the supply dimensions of local renewable sources.
Under the upcoming phases of the project we shall be using the Feasibility Studies to craft produce project funding documents.
