Executive Director of the Institute for Essential Services Reform Fabby Tumiwa was standing as the speaker in Sumba Investment Forum 2017 which was held in Soehanna Hall, Energy Building and organized by the Ministry of Energy and Mineral Resources (ESDM) and Hivos Southeast Asia, on Monday (20/2).

Sumba Investment Forum 2017 was business forum between the governments, both national and regional, and investors to support the achievement of the target for 100 % renewable energy in Sumba by 2025.

Sumba Iconic Island (SII) has become a national priority program to meet the energy needs through the development of potentials for renewable energy . The program developed in Sumba, an island in East Nusa Tenggara is managed jointly by the Ministry of Energy and Mineral Resources (ESDM), Hivos Southeast Asia, PT PLN and local governments and community groups.

Speaking before hundreds of audience, Fabby talked about the on-grid of renewable energy and readiness of PLN in supporting the road map to meet the target of Sumba Iconic Island (SII) in 2020.

He explained that the current condition of electricity in Sumba has reached 30% and 15% are coming from renewable energy.

“The target of this program is to achieve the electrification ratio of 95% with an overall source of energy derived from renewable” Fabby said.

To achieve this goal requires a General Draft of Sumba Energy Supply (RUPES). This design contains a thorough analysis of the importance of this target and analysis regarding network selection off-grid and on grid, expansion plan of of existing grid and construction for the new grid.

“This plan should be developed and supported by private investment and optimizing the national financing” he said.

Further Fabby who also is a member of SII olicy executive team described of two scenarios for electricity production in Sumba for one year. For the high scenario, total electrification will be reached by on grid for 80% while the rest will be contributed from minigrid and off-grid. In the dry season when the water flow and water velocity is reduced, the penetration of renewable Energy is anticipated to reach 87% by pumped storage requirements and a backup power supply is always available . While the lower scenario, total electrification is reached by on grid 70%, and the rest came from mini and off-grid. In the dry season, diesel power plants required to substitute for off grid, and renewable energy penetration is expected of 71%.

Fabby also describes some examples for investment descriptions needs to be adopted. For the basic scenario with a 20 MW hydro strorage entire operating renewable energy generation will require lower investment costs than 10 MW pumped storage scenario strorage, Even so, the cost of power generation to the second scenario would be less than the first.

Fabby said that Sumba has big potentials for renewable energy and target of 100% renewable energy will be possible achieved over the next 10 years if it is supported by field analysis through feasibility study and adequate investment.

“Besides possessing the energy potentials, Sumba also has a favorable investment climate where provincial and local governments are very open to investors and PLN committed to off-taker in the development of networks,” Fabby said closing the exposure.
