Sumba Iconic Island 100% renewable energy An initiative of the 2010 Indonesia-Netherlands Joint Working Group on Energy
Adi Lagur, Field Coordinator (Sumba Iconic Island)
Smart Villages Island Electricity Workshop – E4SV - Bunaken, 3 – 5 Nov 2015
Our approach:
• Holistic, long-term energy development
• Combined energy access and development
• Inclusive, bottom-up planning
• All technologies, all financial models
• Multi-stakeholder
• Inspirational goals
• Joint vision and ambition, not a fixed plan
“100% renewable energy is possible”
A groundbreaking, globally replicable initiative to provide energy to people and businesses.
Why Sumba? • Remote island, high costs for fossil fuels
• Low density population of 660,000
• High poverty rate: average incomes are ¼ of national average
• Low access to electricity: 24.5%
• 10 MW peak load for grid, diesel
• 36.000 households off grid
• Wide variety of potential renewable energy sources: wind, solar, hydro, biogas and biomass
• Support by provincial, local government and PLN
• Transport links to Jakarta via Bali or Kupang
Government the private sector local civil society
multilaterals INGOs international donors
Progress with
stakeholder engagement • MoUs with MEMR and
regional and local
stakeholders
• Research and feasibility
studies
• Demonstration projects
• Regular stakeholder and
working group meetings
to coordinate policies and
activities
• Creation of formal task
force structure and road
map under MEMR Decree

On-grid activities
• Electrification ratio increased from 24% to ~40% in 4 years
• PLN, independent producers: Increased hydro capacity
• BPPT: 500kW centralized solar PV system in West Sumba
• Sewatama, Hivos, Danida: 850kW wind turbine (in preparation)
• MEMR: 1MW biomass plant and 1 MW wind (in preparation 2015-
2016)
• PLN: Grid extensions and improvements
• Feasibility studies for pumped water storage options by AFD/CR

wiring range walking distance range
4 - 6 km 1.5 km
virtual grid extension by battery driven lighting
• Only 154 of 352 villages in Sumba are electrified
• Community-based solutions
• Micro-hydros
• Revitalization of broken mini-grid
• Extension of grid connection
Off grid
• PLN’s solar home systems
(SEHEN): good penetration, but
need to ensure sustainability
• ‘Energy kiosks’ providing sales
and extension services
• Domestic biogas from
Hivos/SNV for clean cooking
and high quality, affordable
fertilizer
• Solar PV irrigation pumps for
farmers’ groups
Economic development
• Increased yields from irrigation and organic fertilizers
• Improved options for post-harvest processing and handling
• Sector development in biogas
• Power in communities for productive use and micro-
enterprises
• Improved grid reliability provides new commercial
opportunities
Case Study – Corn Shelling
Case Study – Flour Grinding
Case Study – Rice Hulling
Key factors – ways to move forward • Acceleration to reach new 2020 target
• Changes and improvements to existing policies to attract investment
• Roadmap revision against new target
• Removing barriers for action
• Not just energy for electricity production, but energy access
• Addressing people’s energy needs beyond lighting
• Replicable concept aligned with stakeholder interests in other islands
