West Nusa Tenggara envisions a 100% renewable energy future

Mataram, Indonesia – ICLEI – Local Governments for Sustainability Indonesia conducted a Visioning Workshop on January27, 2021 in Mataram, West Nusa Tenggara (WNT). The workshop aimed to present energy modelling results and create a shared vision statement that will serve as a foundation for developing the 100% renewable energy (RE) roadmap. Around 20 stakeholders representing provincial and local governments, the private sector, and the academe were involved directly in the formulation of the vision statement. 


Participants shared concerns, interests, and alternative visions to achieve 100% renewable energy in WNT.

Scaling-up an ambitious renewable energy target requires the evaluation of its feasibility supported by technical energy modelling. In cooperation with Fraunhofer ISE, future energy scenarios exhibiting sustainable development in the region were evaluated and modelled based on data collected between August and November 2020. In the workshop, Dr. Annete Streingube shared the initial result of energy modeling.  Different scenarios are simulated by considering multiple energy demand projections, the possibility of connecting Lombok and Sumbawa islands’ energy system, and fuel price conditions. 

The result showed that it is feasible to achieve 100% renewable energy for electricity, cooling/heating, cooking, and transportation purposes in WNT by 2050. Solar photovoltaic and biomass from crop residues are projected to significantly contribute because of their abundant and untapped potentials. The electrolysis process will also be critical to provide heat for industrial processes and hydrogen for transportation in 2050. In addition to the technological perspective, Dr. Annette also provided the cost comparisons for each scenario. She recommended that trading electricity and biomass between Lombok and Sumbawa islands can potentially reduce the cost between 20% and 28%, particularly when the biomass price is low.    


Mr. Hasbulwadi, representing the Tourism Agency, provided several inputs regarding the vision statement of 100% renewable energy in all sectors by 2050.

Developing a comprehensive 100% RE roadmap with appropriate targets and objectives requires a clear vision envisaged by the local governments. The vision illustrates the desired future state of local governments to achieve renewable energy targets related to 100% RE. All stakeholders conveyed their interest, concern, and an alternative vision during the discussion. 

Mr. Julmansyah from the Environment and Forestry Agency suggested that the vision must ensure energy access, energy security, and energy affordability. Furthermore, stakeholder and public participation are required to guarantee its sustainability. A concern on the reduction of regional revenue from fossil-fuel diversion was also raised. However, at the end, the stakeholders agreed that the draft vision is “Terwujudnya NTB 100% Energi Terbarukan 2050” or “To achieve 100% Renewable Energy in all sectors in WNT by 2050. ICLEI will conduct a series of follow-up consultations to increase the stakeholders’ ownership before finalizing the vision. 

The workshop was concluded after the identification of key result areas (KRAs). There were five (5) proposed KRA’s covering policy, technology and resource development, institutional capacity building, financing, and community engagement. The roadmap will incorporate the actions identified in these KRAs .
