Floating the solar dream – pv magazine International


From pv journal 03/23

Indonesian state-owned utility Perusahaan Listrik Negara (PLN) desires 2.4 GW of floating photo voltaic technology capability by 2025, underneath its 10-year marketing strategy.

A report printed by the Institute for Important Providers Reform (IESR) in November 2021 acknowledged that PLN is constructing a 145 MW (AC) website at Cirata Dam and a 60 MW (AC) challenge at Saguling Dam, each in West Java, plus a 90 MW(AC) facility at Singkarak Lake, in West Sumatra.

The Cirata Floating Photo voltaic PV challenge is being developed by UAE-state-owned Masdar Power and PLN subsidiary PT Pembangkitan Jawa Bali Investasi. The Ministry of Power and Mineral Sources spoke pv journal – by means of his Directorate-Basic of New Renewable Power and Power Conservation – that Cirata “36.38%” will likely be full by December 2022, though it’s scheduled to be accomplished that yr. The ministry mentioned that the indoor area necessities for the photo voltaic modules hindered the monetary feasibility and the poor situation of the reservoir mattress had a sophisticated set up of the anchor system.

The floating Saguling and Singkarak initiatives are being developed by PLN unit PT Indonesia Energy and 50% state-owned Saudi developer ACWA Energy which, in October 2020, provided to generate electrical energy at 30% lower than PLN’s tariff of $0.058/kWh, involves $0.041. “We see the nice potential of the nation and its dedication to renewable vitality and net-zero emission targets,” mentioned Salman Baray, nation director of ACWA Energy Indonesia. “We’re working carefully with Indonesia’s largest authorities utility firm, PLN, to assist their necessities.”

Baray additionally cited the issues attributable to getting sufficient photo voltaic panels in Indonesia. “An enormous problem we face is assembly the excessive native content material necessities for photo voltaic – that is one thing that every one photo voltaic builders face and battle to beat,” Baray mentioned. “In reality, it’s virtually unimaginable, at this stage, to satisfy the necessities for utility-related initiatives and we hope that issues will enhance considerably on this space.”

Made in Indonesia

Native content material necessities are established in laws 4/2017 and 5/2017, issued by the Ministry of Trade. The foundations require 34% to 40% of kit – together with photo voltaic modules, inverters, and mounting buildings – to return from Indonesian trade. All challenge providers – corresponding to logistics, set up, and development – should be offered by Indonesian firms.

Concerning the panel content material, 60% should come from Indonesian producers. The plan is for demand to hit 90% by 2025, supported by native polysilicon, ingot, and metallurgical-grade silicon manufacturing, in response to IESR’s “Photo voltaic Power Outlook 2023.” There seems to be no likelihood of that taking place, with the IESR saying that the dearth of cell manufacturing in Indonesia implies that module assemblers can solely obtain 47.5% native content material. The initiatives lack the required regulation consequently.

Knowledge launched by the vitality ministry in 2022 lists 21 photo voltaic panel assemblers in Indonesia with a complete annual manufacturing capability of 1.6 GW. Module elements together with tempered glass, EVA movie, and PV ribbons can’t be produced domestically.

No Indonesian photo voltaic producer has reached 100 MW of annual manufacturing capability. “If we want 150 MW of photo voltaic modules, no firm can promote us that capability,” Baray mentioned. “We have now to purchase it from a minimum of two to a few producers, which creates all types of challenges together with the problem of getting financing. One other problem can also be the usage of previous know-how, which has a value which is about 20% to 30% larger than, say, the price of panels from China.

Banking fears

The dearth of huge photo voltaic firms causes challenge bankability issues. Loans generally utilized by builders require firms to work on modules from tier-1 producers. Tier 1 is outlined as having equipped merchandise to a minimum of six initiatives inside two years and obtained non-recourse finance from six industrial banks throughout the identical interval. Indonesian photo voltaic firms don’t meet that normal.

The IESR says the federal government ought to present flexibility in native content material. “Indonesia has outlined its inexperienced ambitions and is working in the direction of them,” agreed Baray. “Nevertheless, the present restrictions are more likely to stop the achievement of its goals. We should develop native industries by creating enough demand, which is able to permit native producers to increase and make the most of economies of scale . If our firm pays to purchase panels – with previous know-how at the next value – it can enhance the tariff. PLN then has two choices: To go on the extra tariff to clients or to method the Ministry of Finance for subsidies The latter, Baray added, ought to go on to photo voltaic producers, as a substitute of reaching them by means of PLN and photo voltaic builders.

“PLN usually will get a nasty status for asking for extra subsidies,” mentioned the ACWA consultant. PLN didn’t reply to repeated interview requests from pv journal.

IESR’s 2021 report states that steelmaker PT Krakatau Metal is constructing a 12.5 MW (AC) challenge at Krenceng Dam, in Cilegon, West Java, in partnership with renewables developer PT Akuo Power. Aluminum smelter PT Inalum and coal miner PT Bukit Asam are growing 770 kW (AC) at FPV websites at Sigura-Gura Dam in North Sumatra.

These websites will dwarf the challenge put up by Badan Pengusahaan Batam, the federal government company for the free port space of ​​Batam. The set up, at Duriangkang Dam close to Batam Metropolis, is reported by IESR, in 2021, as a 1.7 GW/4 GWh FPV and battery storage plant to be collectively developed by Singapore-based Sunseap. The vitality ministry, nevertheless, just lately introduced that the challenge companion is now PT Batam Sarana Surya subsidiary of coal miner PT Adaro Power Indonesia. The power is presently described as a 1 GW floating photo voltaic plant.

The directorate-general for renewables spoke pv journal that PLN’s PT PLN Batam unit will take 20% of the ability produced on the website, with the remainder being exported to Singapore. There isn’t a set date for industrial operation as a result of the builders are ready to seek out out, from the Ministry of Public Works and Housing, how a lot the reservoir can host FPV. Rules state {that a} most of 5% of the floor space of ​​dams, lakes, and reservoirs will be lined however Batam Sarana Surya desires to cowl 42% of Duriangkang Dam. Authorities permits are additionally required for the event of a forest space.

Some FPV websites are pushed by company sustainability insurance policies, in response to IESR Photo voltaic Analyst Daniel Kurniawan. He’s talking pv journal that “the most important purpose for the rising initiative from industries and companies is their sustainability objectives and the strain to decrease their CO.2 emissions. Additionally it is good for firms to satisfy their sustainability targets and, on the identical time, to scale back electrical energy prices. For companies, in addition they shouldn’t have to adjust to the native content material requirement of PV panels if they don’t promote their electrical energy to PLN.

G20 windfall

Jakarta secured an settlement on the G20 summit held in Bali in November 2022 that may see the governments of the US, Japan, Canada, Denmark, France, Germany, Italy, Norway, and the UK – along with the EU – present $10 billion which is affordable. loans, grants, and fairness funding to assist wean Indonesia off coal. The US mentioned personal monetary establishments will provide one other $10 billion as a part of the $20 billion Simply Power Transition Program.

In return, Jakarta has promised that emissions from the ability sector will start to fall this decade and the nation’s energy will likely be emission-free by 2050. Ministers are engaged on a renewed technique.

Power exports

The scenario relating to clear vitality exports stays unclear, in response to IESR, which says the federal government has but to subject any permits regardless of a minimum of 5 builders wanting. in export-oriented photo voltaic initiatives within the Riau Islands. Builders responded to a name made by Singapore in October 2021 for the provision of “low carbon electrical energy” from 4 GW of technology capability, however Indonesian President Joko Widodo reportedly desires to ban the export of inexperienced electrical energy for worry of lacking home emissions- discount targets. Clear electrical energy exports are allowed so long as native demand is happy, the exported vitality is just not backed, and the standard and reliability of electrical energy is just not affected. Nevertheless, Jakarta has not but issued any permits, in response to IESR.

Whereas the nation presently produces a surplus of electrical energy, it comes from coal-fired energy vegetation, severely proscribing the marketplace for international consumers. With neighboring Malaysia already exporting clear energy, decades-old talks about connecting the ability grids of the ten international locations of the Affiliation of Southeast Asian Nations (ASEAN) have gained new prominence.

“Governments are actually considering severely about tips on how to clear up their electrical energy system – particularly when electrical energy wants in Southeast Asia are anticipated to develop quickly,” mentioned Caroline Chua, a BloombergNEF analyst in Singapore. “Many are in search of an alternative choice to coal-fired energy vegetation.”

The problem, mentioned Chua, is that the ASEAN grids require loads of harmonization when it comes to insurance policies, laws, and market operations, as soon as the grids are related to one another. “ASEAN is geographically divided, not like Europe,” he mentioned. “This raises questions on infrastructure financing, how they combine electrical energy markets, and, in fact, about vitality safety to make sure dependable provide.”

BloombergNEF says that pilot initiatives in the direction of a unified grid community are going down in Thailand, Laos, Malaysia, Vietnam, and Singapore, and there are already cross-border interconnections between some electrical energy markets. Singapore is actively attempting to supply clear electrical energy imports to assist it meet its local weather objectives.

“This instance reveals how a rustic within the Southeast Asian area may also help develop renewables overseas,” added Chua. “The know-how for cross-border energy buying and selling exists. Nevertheless, in the case of financing, it may be very tough, particularly in Southeast Asian international locations the place the ability market continues to be very managed.”
