Abstract

In the past century, fossil fuels have dominated energy supply in Indonesia. However, concerns over emissions are likely to change the future energy supply. As people become more conscious of environmental issues, alternatives for energy are sought to reduce the environmental impacts. These include renewable energy (RE) sources such as solar photovoltaic (PV) systems. However, most RE sources like solar PV are not available continuously since they depend on weather conditions, in addition to geographical location. Bali has a stable and long sunny day with 12 hours of daylight throughout the year and an average insolation of 5.3 kWh/m2 per day. This study looks at the potential for on-grid solar PV to decarbonize energy in Bali. A site selection methodology using GIS is applied to measure solar PV potential. Firstly, the study investigates the boundaries related to environmental acceptability and economic objectives for land use in Bali. Secondly, the potential of solar energy is estimated by defining the suitable areas, given the technical assumptions of solar PV. Finally, the study extends the analysis to calculate the reduction in emissions when the calculated potential is installed. Some technical factors, such as tilting solar, and intermittency throughout the day, are outside the scope of this study. Based on this model, Bali has an annual electricity potential for 32-53 TWh from solar PV using amorphous thin-film silicon as the cheapest option. This potential amount to three times the electricity supply for the island in 2024 which is estimated at 10 TWh. Bali has an excessive potential to support its own electricity demand with renewables, however, some limitations exist with some trade-offs to realize the idea. These results aim to build a developmental vision of solar PV systems in Bali based on available land and the region’s irradiation. Keywords: Energy modelling, solar PV, energy policy

Abstract

This study investigates enabling conditions for facilitating social innovation in the energy sector. This aspect is important to support the energy transition in Indonesia. This research provides appropriate project direction, including research (and action) gaps for the energy actors in Indonesia. The actors are encouraged to work further with the result of this study to stimulate the energy transition in Indonesia. This study uses a systemic change framework which recognizes four drivers of systemic change in a region: 1. transforming political ecologies; 2. configuring green economies; 3. building adaptive communities; 4. social innovation. These drivers are interconnected, and this study focuses on how the social innovation can be supported by other drivers. This study used interviews and literature review as the sources of data. There were interviews with eight experts who come from different countries and are experienced in social innovation in the energy sector. Afterward, this research reviewed related journal papers from the last five years, to check the latest developments within the topic, to support the interview results. The study found that the enabling condition can focus on one of the drivers of systemic change, which is building communities by increasing their participation, through several integrated actions. This point can be implemented in two types of citizen energy initiatives which are energy cooperatives and sustainable consumption initiatives. Further implementation of these initiatives requires a study on policy and governance support, to create complete enabling conditions to facilitate social innovation in the energy transition.

Abstract

The impacts of high dependence on oil on the economy have encouraged many countries to start eliminating or sharply reducing their dependence on oil consumption. As an oil importer as well as oil and gas producer country, Indonesia seeks to do the same thing by eliminating fuel subsidies, shifting to gas, and developing renewable energy. The oil price affects the economic and energy policies and impacts the efforts of reducing oil dependence. Using an econometric model of Indonesia’s energy that is constructed based on its energy balance model, this paper will examine factors that influence the oil demand in Indonesia. It will estimate the country’s energy needs from 2017 to 2030 and simulate various alternative strategies to deal with oil dependencies, such as an increase in the refinery capacity, and a shift from oil to gas in the transportation sector. This paper suggests that shifting from oil to gas in the transportation sector will be able to reduce oil dependency, while the alternative of increasing refinery capacity to 3 million barrel per day will be an opportunity to support greater short-term energy security and economic returns. Keywords: Economy, econometric, energy, oil dependence, sustainable energy security

Abstract

More than the half of Indonesian households primarily rely upon firewood for cooking. To overcomecthis problem, multiple initiatives established the decentralized biogas programs. This paper aims to analyze the environmental problem of firewood cooking and to find out various challenges and opportunities for biogas dissemination in rural areas in Indonesia. The method used in this paper is literature review with frameworks of DPSIR and stakeholder matrix. The result found that the firewood cooking is adversely impacting local wooded ecosystems, deforestation rate and negative effect on human respiratory health. The biogas programme is still not able to replace the firewood use. The research found that it is caused by two major challenges. The first one is the issue with the project's approach in which biogas programmes are still dominated by the government grants. This situation leads to community dependency on the grant, lack of investment and low demand and market in this sector. The second challenge is the technology part where many biogas digesters were not operated due to the low quality of installation, and lack of knowledge and skill of the biogas user about the maintenance and installation of the digester. This study suggests that there is the opportunity to improve the approach of governmental biogas programme. It has to involve more roles from non-state actors. In the user side, the farmers as majority user also should be trained properly how to maintain the biogas installations. As the solution, instead of the full grant, the programme can reduce the percentage of subsidy and turn the cost to provide more digesters and training. Key stakeholders need to have cooperation to increase the quality and quantity of the biogas dissemination. Keywords: Biogas, firewood, programme, technology, Indonesia

Abstract

In the wake of a new fiscal system related to oil and gas industry in Indonesia, namely the gross split system, concerns have been risen due to the fact that the new regulation puts forward EOR as an obligation for oil and gas contractors in order to gain significant incentives to improve field economics. Although EOR itself is a mature and proven technologically and economically to alleviate oil production thus encouraging profitable business, it has to be realized that most greenfields in Indonesia are relatively small compared to previous discoveries or case studies encountered abroad, rendering EOR to be economically obsolete to be implemented in full field scale. This study presents a new concept and suggestions for stakeholders to implement massive tertiary recovery in oil reservoirs around Indonesia using the less expensive and more result oriented, reducing the need for lengthy procedure before full scale EOR can take place. Keywords: Enhanced oil recovery, gross split, huff & puff
