The progress of Indonesia’s vitality transition hinges largely on funding within the sprawling archipelago’s electrical energy grid infrastructure to soak up renewables and allow cross-border energy buying and selling, mentioned business watchers at a Jakarta occasion final Thursday.
Indonesia is residence to a medley of various vitality methods dotted throughout 6,000 inhabited islands, with the Java-Bali energy system – the biggest within the nation thus far, with 64 per cent of complete put in capability – among the many solely grids that join varied islands. Talking on the Unlocking capital for sustainability occasion on the Ritz-Carlton Mega Kuningan lodge, Ricky Faizal, electrical energy system planning and management vp at Indonesia’s nationwide vitality utility PT Perusahaan Listrik Negara (PLN), mentioned that with a purpose to increase renewable vitality capability within the nation and meet local weather targets, higher connectivity between electrical energy grids is essential.
To remain on observe to realize its 2060 net-zero goal and produce extra renewables into the vitality system, the archipelago will must be shut to totally related by 2035, mentioned Faizal.
A scarcity {of electrical} grid connectivity has meant an elevated reliance on captive coal crops to energy Indonesia’s booming nickel business, which satirically is considered one of Indonesia’s fastest-growing emissions sources because the nation pursues an ambition to be a transition minerals powerhouse.
“
There’s a have to spend money on grid infrastructure. That may allow regional energy sharing, which might be a tipping level within the vitality transition.

Indonesia’s vitality connectivity problem is difficult by a “mismatch” in demand and provide, Faizal defined. Java, probably the most populous island, and tourism hotspot Bali account for 70 per cent of Indonesia’s complete vitality demand; whereas much less populous Kalimantan, Sulawesi and Sumatra have their very own distinctive vitality methods designed to handle decrease energy masses.
Including intermittent renewables – the state utility plans to add 33.2 gigawatts (GW) of renewables capability from 2024 by way of to 2033 – presents stability points that grid upgrades might want to account for. “We are able to enhance renewables vitality capability, however it’s going to take funding and time,” mentioned Faizal.
A plan to construct a “tremendous grid” that connects the Indonesian archipelago is estimated to price US$1.5 million per kilometre of submarine cable alone, with energy converter prices operating to US$300-400 million per GW. Current stories pitch the overall price at US$25 billion.
Nonetheless, the tremendous grid has struggled to draw funding. A PLN govt lately conceded that the return on funding on transmission traces will not be as excessive as for energy era, so it has been tough to crowd in non-public capital.
The grid could also be partly financed by the Simply Power Transition Partnership (JETP), an settlement to mobilise an preliminary US$20 billion in funding from developed nations to decarbonise Indonesia’s vitality sector, though Indonesian ministers have bemoaned the issue in accessing this capital.
On the Unlocking capital for sustainability Indonesia occasion, audio system together with (from left) Sahid Junaidi, secretary of the Directorate Common of recent renewable vitality and vitality conservation at Indonesia’s vitality and mineral sources ministry, Karna Mohan, vp finance, Asia Pacific, Siemens Power, Dr Nuki Agya Utama, govt director of Asean Centre for Power, Enda Ginting, nation supervisor, Indonesia at Gurîn Power, and Ricky Faizal, vp, electrical energy system planning and management at PT PLN, mentioned the significance of creating coverage frameworks and capital mobilisation for the nation’s sustainable transition. The session was moderated by Meaghan See, director of partnerships, Eco-Enterprise. Picture: Eco-Enterprise
Regional energy sharing potential
The intermittency problems with including renewables to the grid might be eased by sharing the facility load and any extra provide throughout jurisdictions, which underscores the significance of a transmission infrastructure improve, mentioned Dr Nuki Agya Utama, govt director of Asean Centre for Power, a assume tank.
Nuki mentioned {that a} good grid – that’s, a community that may reply to modifications in utilization – is additionally wanted, in addition to battery storage methods to handle variations in demand as regional vitality buying and selling takes off. Indonesia signed a take care of Singapore to extend clear vitality commerce final September.
Northern Kalimantan and the Malaysian state of Sabah on the island of Borneo are prime candidates for cross-border energy sharing, though upgrades to transmission infrastructure and feasibility research are wanted earlier than renewables can be added to the grid, Nuki mentioned.
Whereas financing assist in vitality infrastructure in Southeast Asia has been rising, with 12 months on-year investments in inexperienced expertise within the regional bloc rising by 20 per cent in 2023, and Indonesia accounting for the majority of progress, there stays a “large finance hole”, mentioned Karna Mohan, vp of finance, Asia Pacific, for Siemens Power, an infrastructure expertise agency that transmits 40 per cent of Indonesia’s energy.
Southeast Asia at the moment accounts for simply 2 per cent of worldwide funding in renewable vitality, and the common annual funding of US$70 billion might want to a minimum of double to satisfy international local weather targets, mentioned Mohan. Indonesia will want an estimated US$150 billion to US$200 billion per 12 months between 2021 and 2030 to decarbonise its vitality sector, in accordance with projections by Indonesia’s planning ministry. Mohan added that the nation will even have to overhaul its regulatory framework to allow renewables to realize worth parity with fossil fuels, past crowding in funding.
Indonesia depends on fossil gasoline subsidies, which totalled US$12 billion this 12 months, in accordance with the Ministry of Power and Pure Sources (ESDM). The introduction of carbon tax on heavy business, slated to come back into play this 12 months, ought to assist to degree the enjoying area for clear vitality, Mohan mentioned.
Unlocking capital for sustainability is an annual flagship occasion on sustainable finance for Asia Pacific organised by Eco-Enterprise in partnership with UN Surroundings Programme (UNEP). The following regional version might be held in Kuala Lumpur, Malaysia, on 24 July 2024. Register to affix us on the occasion.
