Awaiting Regulatory Certainty for Solar Energy Adoption

Fabby Tumiwa dalam konferensi pers Smart Transportation and Energy di Indonesia pada Kamis (9/11/2023)

Jakarta, November 9, 2023 – Solar power has the potential to accelerate renewable energy in Indonesia’s primary energy mix. However, developing the country’s solar power plants has proved challenging. The Executive Director of the Institute for Essential Services Reform (IESR), Fabby Tumiwa, explained that Indonesia has the highest potential in solar energy. An IESR study shows that solar power in Indonesia could reach a technical potential and land suitability of 3,000-20,000 GWp. Despite this potential, there are regulatory challenges to developing solar energy in the country, particularly regarding solar PV. In 2022, the realized installed capacity of solar PV was only 271.6 MW, which was far below the planned capacity of 893.3 MW, based on data from the Directorate General of EBTKE of the Ministry of Energy and Mineral Resources.

“Solar PV utilization is currently limited to around 10-15% of its capacity, which makes the economics of solar PV low and unattractive. In 2021-2022, the growth of rooftop solar PV has stagnated. However, since the beginning of this year, there have been efforts to revise the regulations to prevent uncertainty. The revision process is long and has even been discussed at the Ministry of Law and Human Rights (Kemenkumham). Unfortunately, the process has not been completed yet and still requires further coordination between Ministries and Institutions,” said Fabby Tumiwa at Thursday’s Smart Transportation and Energy in Indonesia press conference (9/11/2023).


Fabby Tumiwa mentioned the uncertainty must be resolved immediately with strong leadership from President Joko Widodo (Jokowi). Additionally, on Thursday (9/11/2023), Indonesia unveiled the Cirata Floating Solar Power Plant, which has a capacity of 192 MWp, making it the biggest floating solar power plant in Southeast Asia.

“The inauguration of the Cirata Floating Solar Power Plant signifies the Indonesian Government’s commitment to developing solar energy. This project could not have been completed without the use of advanced technology and innovation from China, the world’s largest producer of solar energy technology. Considering Indonesia’s plan to increase the usage of renewable energy, we anticipate a significant demand for solar power plants in the coming years,” explained Fabby Tumiwa.

INDONESIA-CHINA Energy Transition Cooperation, First Of Its Kind High-Level Dialogue

INDONESIA-CHINA Energy Transition Cooperation, First of its kind high-level dialogue to advance renewable energy cooperation between Indonesia and China


26 September 2023 – The Coordinating Ministry for Maritime Affairs and Investment (CMMAI) of the Republic of Indonesia conducted a first of its kind high-level dialogue between Indonesia and China officials to deepen cooperation between the countries on energy transition. The dialogue was co-hosted by the Ministry,  Indonesian think-tank Institute for Essential Services Reform (IESR), China’s multi-stakeholder BRI International Green Development Coalition (BRIGC) and international environmental law NGO ClientEarth. The dialogue forms the basis for a report that IESR, BRIGC and ClientEarth will issue on China’s role in accelerating Indonesia’s energy transition. 

The dialogue brought together representatives from both governments’ institutions and key industry leaders to present and exchange views from both nations to find common ground for establishing cooperation, especially in the energy sector. High-level representatives from agencies and entities such as from the Coordinating Ministry of Maritime Affairs and Investment, Ministry of Investment, PLN, Ministry of Energy and Energy Resources, and Ministry of Industry from Indonesia and National Development and Reform Commission, Ministry of Commerce affiliated institute, China Development Bank, BRI International Green Development Coalition, China Renewable Energy Engineering Institute and China Renewable Energy Industries Association from China attended the event. 

This year marks the 10th anniversary of the announcement of the Belt and Road Initiative (BRI). It is also the 10th anniversary of the comprehensive strategic partnership between China and Indonesia. Over the past decade, China has increasingly prioritised cooperation on green development and has implemented a number of green, low-carbon, and sustainable clean energy projects. With the technology and cost advantages, this mutually beneficial partnership can bring leap-forward opportunities for Chinese investors, and tap into low-carbon transition in Indonesia.

Between 2006 to 2022, Chinese investments in Indonesia accounted for approximately USD 35 billion. A quarter of these total investments is channelled into the energy sector. However, 86% of this is for the fossil fuel energy industry. In line with  President Xi Jinping’s pledge at the 76th Session of the United Nations General Assembly, China announced that it will “step up support for other developing countries in developing green and low-carbon energy, and will not build new coal-fired power projects abroad.” One of the five proposals made by President Xi at the 30th Anniversary of China-ASEAN Dialogue Relations is to “jointly promote regional energy transition, discuss establishment of a China-ASEAN clean energy cooperation center, and enhance technology sharing in renewable energies” and to “intensify cooperation on green finance and investment to support regional low-carbon and sustainable development”. 

This dialogue was conducted to understand both Indonesia and China’s development, especially in the field of sustainable energy and its manufacturing industries. The government of Indonesia has made a commitment to achieve net-zero emissions by 2060. To reach this target, an estimated investment of USD 1.1 trillion translating to 768 GW of renewable energy capacity needs to be installed. Solar will be the leading technology in Indonesia’s net-zero transition due to its large potential, low cost, and modularity. Indonesia also holds large global reserves of minerals needed for solar cells and batteries. It is therefore expected that demand for solar modules and other components in Indonesia will rapidly increase in the next five years.

Fabby Tumiwa, Executive Director of IESR, said, “Sustainability has become a core part of high-quality BRI cooperation and there are huge investment opportunities between the two countries to accelerate the green and low carbon transition of Indonesia’s energy system. It is technically and economically practicable to achieve zero carbon emissions by 2050 by decarbonising Indonesia’s energy system. This will require widespread electrification of key transport sectors, vast deployment of renewable energy, phase down of fossil fuel infrastructure, use of vast quantities of storage and electrolysers to balance supply and demand, as well as energy carriers for transportation and industry, and reliable grid connectivity between Indonesian islands.”

To deepen China-Indonesia green and low carbon cooperation, the draft report “Critical role of China on accelerating Indonesia’s energy transition” was presented during the dialogue. Elizabeth Wu, Legal Consultant from ClientEarth’s Energy Systems, Asia team, moderated a roundtable on the findings of the report. The roundtable considered: 

  1. Strengthening high-level renewable energy partnerships between China and Indonesia through the development of joint long-term strategies and concluding bilateral agreements. 
  2. Exploration of innovative mechanisms and financing structures to increase green project pipelines and BRI demonstration zones and pilot projects; and 
  3. Deepening exchanges and exploring further integration with ASEAN regional strategy.

Dimitri de Boer, ClientEarth’s Regional Director of Programmes for Asia expressed his thanks for the warm support from the officials and participants and said: “The Belt and Road Initiative can play a vital role in the global energy transition, by working with partner countries like Indonesia to really scale up renewable energy deployment.”

China’s Belt and Road Initiative Opportunities in Accelerating the Energy Transition in Indonesia


Beijing, March 27, 2023 – The Executive Director of the Institute for Essential Services Reform (IESR), Fabby Tumiwa, highlighted that the Belt and Road Initiative (BRI) allowed China to play a role in accelerating the energy transition in Indonesia. He mentioned this as a guest speaker promoting green and low carbon transition in BRI participating countries and  CCICED particular policy study on green BRI workshop on Monday (27/3/2023).

“Indonesia must increase its ambition to make emission reductions compatible with the Paris Agreement. Under the current plan, Indonesia will achieve the energy sector’s net zero emission (NZE) after 2060, but the electricity sector will reach zero in 2050. For this reason, we need more efforts to decarbonize the transportation and industrial sectors,” explained Fabby.

He also underlined that Indonesia needs a cumulative investment of around USD 1.3 trillion spread across various technologies in the push for decarbonization. Under these conditions, Fabby said, China could play a role in supporting the energy transition in Indonesia through technology, manufacturing, and investment cooperation, considering that there is market potential in increasing demand for renewable energy in Indonesia.

“Solar power will play an important role in Indonesia’s energy transition. Based on the 2021-2030 Electricity Supply Business Plan (RUPTL), PLN plans to add 3.9 GW of solar energy in 2025. For this reason, BRI’s investment in 2023 needs to be focused on financially feasible projects, such as scalable solar and wind power plants, said Fabby Tumiwa.

On the other hand, the existence of BRI can enable investment in the renewable energy component industry. This can be done by considering the complexity of the supply chain. Fabby emphasized that industrialization in Southeast Asia accompanied the push for the energy transition, such as energy storage, electric vehicles, and solar panels.

“Currently, Indonesia has started to develop the battery and electric vehicle industry because of its great nickel content. Low production costs and availability of resources are several opportunities to develop the local solar module industry in Indonesia,” said Fabby.

On the same occasion, Deon Arinaldo, Energy Transformation Program Manager, Institute for Essential Services Reform (IESR), explained various power system plans and projections expected to accelerate the spread of renewable energy in Indonesia. For example, the latest power system energy planning stipulates around 20.9 GW of renewables to be built in 2030. This number will increase by at least 5-6 GW if Indonesia considers the Just Energy Transition Partnership (JETP) target of 34% renewable energy mix in 2030.

“To achieve the national policy target in 2025, the IEA projects an additional solar energy capacity of 17.7 GW above that planned in the RUPTL. Meanwhile, based on the IESR scenario, the power generation capacity based on renewable energy must be boosted to 140 GW to limit global warming to 1.5°C,” Deon explained.

However, said Deon, historically, the installed capacity of renewable energy has only grown around 500 MW per year. This happened because there were several main challenges, including excess capacity at the Java-Bali power plant. Moreover, the domination of coal power plant capacity with a take-or-pay mechanism needs to make room for the integration of renewable energy. Another challenge is the renewable energy procurement process and the requirements for using local content, which places unnecessary risks in developing renewable energy.

Total support from the Government is required for a promising solar energy

“Solar cells will be the new promising commodity in the future, just like oil now,” said Fabby Tumiwa during his explanation in the REinvest Indonesia – China forum.

The forum aims to bridge the two countries in renewables investment collaboration. Indonesia is actively seeking a way to provide cleaner, cheaper, and more reliable energy sources in order to revitalize its current energy system that heavily relies on fossils. Meanwhile, China faces global force as well to reduce its carbon emission due, and pledge to be carbon neutral by 2060. As the two countries have things in common to reduce carbon emission, dialogue to bridge the needs is set-up. 

Fabby Tumiwa, in his capacity as the chairman of Indonesia Solar Association and Executive Director of IESR, said that Indonesia needs to accelerate the renewables deployment to seize the target of RUEN i.e 23% renewables in national energy mix and further to be zero emission in 2050. Even though the government of Indonesia set the target to be net zero emission in 2070.

Solar PV can be the prime mover and key to achieving the decarbonization target. This is in line with the global urgency to have deep decarbonization. Mentioned by IEA in the latest report that solar and wind will dominate the energy system in the future up to 78% of power generation in 2050, in which solar should increase from 160 GW now to 650 GW in 2030. On the same occasion, IEA emphasizes the urgency to scale up renewables in this decade to achieve zero-emission in 2050. In terms of a strategic point of view, solar is a bit more privileged as it is able to be installed modularly. In the future solar energy is a popular commodity just like oil in the present day. 

However, the promising future is not coming without any flaws. There are a bunch of situations that hold back the acceleration of the solar PV industry in Indonesia. 

PLN’s oversupply condition is one of the most significant barriers to solar deployment. The situation makes it hard for both the government and private sector to penetrate renewables into the electricity system. 

Meanwhile, Eka Satria, CEO Medco Power Indonesia, highlighted some points including the preference of the government and Indonesian market to choose short-term low-cost energy sources, the uncertainty of policy and regulation, BPP vs local content requirements, and also land acquisition issue. 

As the chairman of the Indonesian Solar Panel Producers Association (APAMSI) Linus Sijabat shares things that should be prepared by the foreign investor in this occasion China, before penetrating the Indonesian market. Supply chain management, especially related to the local content requirement becomes his key point. 

“Foreign and domestic cooperation is required for products of more than 60% whose prices are competitive, the quality is internationally certified, and the market is sustainable,”

The willingness of the government must be shown in the regulation such as RUPTL (general planning of electricity compliance) so private investors will be able to see the potential market for renewables in Indonesia. Moreover, in Indonesia PLN stands as the single buyer for electricity. Besides the chance that should be visible in the planning document, another enabling environment for renewables investment must be ensured as well.

Bringing Indonesia to The Gigawatt Club:  Unleashing Indonesia’s Solar Potential

With energy transition becoming a global trend following action to mitigate climate crisis, many countries have integrated low-carbon energy systems into their national development agenda. Indonesia has the highest energy demand among ASEAN members, and fossil fuel resources still dominate Indonesia’s energy and electricity mix: less than 12% primary energy supply was from renewable sources, and the renewables only provided ~14.9% of Indonesia’s electricity generation in 2020 (IESR, 2021). Although Indonesia has established its renewable energy targets, i.e., 23% of primary energy mix by 2025, renewables growth in the country is slow, even stagnant over the years.

Indonesia is often called a frontier market for renewable energy, and that includes solar energy. While the technical potential is high, up to 207 GW according to Ministry of Energy and Mineral Resources, solar generation in the country is less than 1% – this slow growth is a combination of several inhibiting factors: lack of consistent and supportive policies, the absence of attractive tariff and incentives, as well as concerns on grid readiness. Solar energy will be key to open the doors for other renewables in Indonesia; along with the current government’s plan to issue presidential regulations on renewable energy pricing and deployment.

To support accelerated solar deployment in Indonesia, in March 2020, the Institute for Essential Services Reform (IESR) signed an MoU with the Global Environmental Institute (GEI) to collaborate on renewable energy development. To this end, we conducted two training sessions and technical exchanges on technical potential analysis of renewable energy resources by applying the Renewable Energy Implementation (REI) toolkit.

To date, with the supports from GEI, IESR has completed a GIS-based nationwide solar PV technical potential assessment in Indonesia. The assessment report is produced to provide detailed information for related stakeholders in identifying prospective locations for solar power plants at any scale, feeding energy planners and driving more ambitious solar development in Indonesia. The interests and growth need to be nurtured, yet the big question remains: what more Indonesia can do to enter the gigawatt solar installations?
