In October 2023, Nickel Industries signed a binding agreement for solar power at Indonesia Morowali Industrial Park in Central Sulawesi without having to fund the equipment. SESNA would develop, install, operate and maintain the project. The buyer said its indicative electricity price was materially below its existing power costs, although it did not disclose the price. [3]
That transaction changes the question for anyone hoping to build a solar company for Indonesia’s nickel producers. Financing the panels is already a business. The opportunity worth examining is whether a new developer could deliver additional electricity sooner—and still earn a return after leaving the buyer a saving.
The plant buys useful electricity, not panel capacity
Nickel processing can use electricity to heat furnaces that turn ore into metal. Many Indonesian facilities are remote and depend on coal-fired power built for industrial use. WRI’s January 2026 analysis reported 55 operating nickel-processing facilities and about 100 billion kilowatt-hours of sector electricity use in 2023. A kilowatt-hour, or kWh, measures energy consumed and billed. [2]
The climate stakes are substantial, but they are not automatically a supplier’s revenue. Katadata’s November reporting describes the dispute over Indonesia’s “green nickel” claims and continuing coal dependence; it does not establish a premium that buyers will pay for cleaner nickel. A solar developer would need to earn its money from the electricity budget. It would leave fuel used directly in processing, and much of the cost of existing coal infrastructure, untouched. [1][2]
Solar adds another constraint: maximum panel capacity is not a promise of round-the-clock power. MWp, or megawatts peak, describes the panels’ rated maximum output. Sunshine varies, and the plant’s electrical system must be able to accept the energy when it arrives. The proposed company would sell this usable, metered energy while existing supply maintained production continuity. The technology catalogue describes solar’s variable output and integration requirements; an actual site study must establish how much can be used. [5]
Buyers already have several ways to procure it. In June 2026, transaction adviser DLA Piper reported financing for a 262 MWp solar project with 80 megawatt-hours of battery storage at Morowali, costing approximately US$210 million and targeting operation in early 2027. That is evidence of a financed project, not completed output. Xurya offers performance-based monthly leasing and outright purchase; SUN Energy offers rental, leasing and purchase. No numerical tariff for a comparable nickel site is public in these sources. [4][7][8]
These suppliers sell capital and delivery capability as well as hardware. SUN’s October 2026 announcement of a mining-electrification development in Berau is another sign of competition for industrial customers, although it does not establish nickel-plant delivery. IMIP also reports solar adoption among its tenants. A new company would be competing for additional, uncontracted work against established developers and the owner’s option to buy a system itself. [9][11]
Make the next site easier to deliver
The Repeat-site solar developer for nickel plants would start with authorised plant owners and park power purchasers in Sulawesi. Its hypothesis is simple: reuse engineering where sites genuinely match, build local construction relationships and settle connection requirements early enough to deliver useful energy sooner than a competing developer or an owner-appointed contractor.
Day to day, the team would obtain the buyer’s electricity-use records and authority to develop the site, commission the necessary engineering, agree who bears the risk of rejected output or shutdowns, and secure financing before ordering equipment. It would then build, meter and maintain the system, collecting long-term payments for accepted energy. If the buyer shuts down or cannot use the output, the capital still has to be repaid. A minimum bill would protect the developer by leaving some of that risk with the buyer; those terms would need agreement before financing. Engineering contractors would gain paid repeat work; financiers would require a creditworthy buyer and contracts that support repayment. The park operator would need both a reliable system and a share of the economic benefit.
An experienced industrial-energy team could seek its first introductions through engineering contractors already dealing with owners’ procurement staff. Conversion would require a priced offer, a credible start date and agreement from the people controlling the site and network. Official electricity-administration guidance distinguishes different supply and self-supply structures; it is a reason to check the actual contracting authority, not evidence that this proposal already has permission. [10]
The hoped-for advantage is speed, supported by reliable execution and easier purchasing. There is no evidence here that SESNA is generally slow or unable to reuse designs. The years between a historical agreement and a later financing announcement do not establish delay attributable to the supplier. An incumbent could match the method; repeated delivery would have to build buyer trust, operating records and lower development costs before it became more than a temporary advantage.
The saving has to pay for the capital
A calculation shows how little room there may be. Using a generic Indonesian solar benchmark, an assumed exchange rate and an assumed 25-year investment period, one MWp would require about Rp12.8 billion upfront. Assume it supplies 1.5 million accepted kWh each year and charges Rp1,000–1,200 per kWh: annual receipts would be Rp1.5–1.8 billion. These are a commercial illustration, not a supplier quotation or measured demand. [5][6]
The developer has to recover the investment and compensate those providing the money. Applying financing-return assumptions of 8.5–11%, informed by the IEA’s Indonesian solar benchmarks, gives an annual capital allowance plus basic maintenance of roughly Rp1.35–1.62 billion per MWp. The remainder ranges from a loss of Rp120 million to a surplus of Rp449 million a year—before additional land, storage, electrical integration, taxes, replacement equipment, customer acquisition and company overhead. At the high financing rate and high selling price, 10% less accepted electricity consumes almost all that remainder. [5][6]
| Assumed price | Annual receipts | Remainder at 8.5% | Remainder at 11% |
|---|---|---|---|
| Rp1,000/kWh | Rp1.50bn | Rp149m | −Rp120m |
| Rp1,200/kWh | Rp1.80bn | Rp449m | Rp180m |
Nor is a service contract necessarily the buyer’s cheapest choice. On the same assumptions, buying the equipment rather than paying the service bill recovers the upfront cash in about 7.5–9.1 years, after basic maintenance. Allowing for the time value of money pushes the crossover to roughly 12.5–18.4 years in three of the four cases; in the fourth it does not occur within 25 years. Ownership therefore deserves a real bid alongside the service. The developer must sell valued relief from financing and execution work, or an earlier useful start, sufficient to justify its price. [5][6]
Earlier delivery has value only when the displaced electricity costs more than the solar bill. For a labelled hypothetical example, take 125,000 usable kWh a month, alternative electricity costing Rp1,400/kWh and solar at Rp1,100. Three months earlier saves the buyer Rp112.5 million. It does not save the full solar bill. Continuing existing coal power might cost less than either assumed price; only the plant’s avoidable cost—the spending that actually disappears when it uses less coal power—can settle that comparison.
This is also why buying panels speculatively is risky. In the same illustration, holding the full Rp12.8 billion investment idle for three months at 8.5% incurs about Rp272 million in simple carrying cost. Actual projects need not tie up all their equipment that way. The point is to commit equipment after the site and funding, so that the pursuit of speed does not consume the value it creates.
A sizeable contract is not an open market
Starting from WRI’s dated count of 55 facilities, assumptions about reachable Sulawesi sites and which have suitable land, buying authority, credit and uncommitted projects narrow the first market to roughly 4–12 potential sites in the calculation. Assuming 10–20 MWp at each and winning 20% of eligible work gives annual company receipts of about Rp13–83 billion. These are scenarios built from unmeasured eligibility and adoption shares, not a list of willing customers; several facilities may answer to the same buyer. [2]
That range could support a project-development company if the contracts leave a positive return after all costs. At the favourable end of the earlier illustration, a 10 MWp contract leaves about Rp4.5 billion a year before the omitted costs; at the adverse end it loses about Rp1.2 billion. More contracts would amplify either result. Repeating the same model at other Indonesian nickel sites offers a logical growth route, while other industrial processors are a possible later market rather than counted revenue.
The best next step is one real buying decision. Before construction, seek an authorised site’s operating data and compare priced, dated offers from an established developer and an owner-appointed contractor. Ask engineers and financiers to check usable output and every additional cost, then seek a conditional purchase commitment. The idea weakens sharply if no price both saves the buyer money against its cheapest adequate option and pays the developer’s full costs—or if the incumbent can supply the same energy just as soon.
Financed nickel solar is documented. A profitable speed advantage for a new company is still a hypothesis. Plant energy buyers who can share avoidable electricity costs, engineers who can price the connection work, and lenders who can price the proposed contracts could resolve it more cheaply than a speculative construction programme.

Economics workings: the weakest input is usable output at a real site
All following calculations are illustrations/scenarios, not customer commitments or project forecasts. Capital K = US$0.80/Wp × 1m Wp × assumed Rp16,000/US$ = Rp12.8bn/MWp. Maintenance = US$7,500/MWac/year ÷ 1.2 MWp/MWac × Rp16,000 = Rp100m/MWp/year. The assumed constant 1.5m accepted kWh/MWp/year is informed by the gross-yield benchmark; actual rejected output, outages and degradation can reduce it. Assumed tariffs Rp1,000–1,200/kWh give Rp1.5–1.8bn annual receipts. [5]
Annual capital allowance = K × r ÷ [1 − (1+r)−25], using an assumed 25-year horizon. Add Rp100m maintenance to obtain Rp1,350,709,536 at r=8.5% and Rp1,619,875,098 at r=11%. Do not add another interest charge to this blended-return allowance. At Rp1,000/kWh, residuals are Rp149,290,464 and −Rp119,875,098; at Rp1,200, Rp449,290,464 and Rp180,124,902. These are capital-adjusted remainders, not accounting contribution margins or project internal rates of return. Land, batteries, remote integration, taxes, replacements, degradation, acquisition and overhead remain to be priced. The IEA’s post-tax benchmark does not make this simplified cash-flow screen tax-complete. [5][6]
At 11% and Rp1,200/kWh, accepted output falling 10% cuts receipts by Rp180m, leaving only about Rp125 per MWp annually before extras. Scaling to 10 MWp gives the story’s favourable Rp4.49bn and adverse −Rp1.20bn annual remainders. An assumed Rp1bn acquisition/development allowance for a won 10 MWp project has an annual equivalent of about Rp98–119m using the same recovery formula; actual site engineering, legal work and failed-bid spending must replace this allowance. It is not observed customer-acquisition cost.
Ownership comparison assumes the identical system, output and maintenance. Simple crossover = K ÷ (avoided annual lease − maintenance): 9.14 years at Rp1,000/kWh and 7.53 at Rp1,200. Discounted crossover solves K = (avoided lease − maintenance) × [1 − (1+r)−t] ÷ r. At 8.5%, t=18.40/12.52 years for low/high tariff; at 11%, the high tariff gives 16.88 years and the low tariff has no crossover within 25 years. Taxes, degradation, replacements, residual value and different execution risks are omitted on both sides. Actual ownership can win, and actual continued fuel/grid supply may be cheaper still.
Speed example: assumed 1.5m kWh/year ÷ 12 = 125,000 kWh/month; three months × 125,000 × (assumed Rp1,400 alternative − assumed Rp1,100 solar) = Rp112.5m buyer saving. Full-asset simple carry: Rp12.8bn × 8.5% × 3/12 = Rp272m. These are hypothetical values explaining the relationship, not measurements of an incumbent’s delay or inventory practice.
From a facility count to annual supplier revenue
Initial Sulawesi scenario: 55 facilities [2] × assumed 40–60% reachable geographically × assumed 20–35% suitable, authorised, creditworthy and uncommitted = 4.4–11.55 facility-equivalents. At assumed 10–20 MWp each × 1.5m accepted kWh/MWp/year × Rp1,000–1,200/kWh, annual revenue per facility is Rp15–36bn and the eligible total Rp66–415.8bn. Assumed 20% capture = Rp13.2–83.16bn annual company revenue, representing approximately 0.88–2.31 facility-equivalent contracts at corresponding ends. Fractional facilities express scenario arithmetic; awards are discrete and gatekeepers may control several plants. The unmeasured eligibility shares can reduce the market to zero.
National sizing retains the same nickel-electricity job and Sulawesi-to-other-Indonesian-nickel-sites route at both ends. Total annual supplier-revenue scenario (TAM): dated 100bn kWh [2] × assumed Rp1,000–1,500/kWh = Rp100–150trn. Serviceable annual revenue (SAM): assumed 1–2% economically accessible incremental substitution = Rp1–3trn. Year-five attainable company revenue (SOM): assumed 2–4% of SAM = Rp20–120bn/year. These are conditional revenue envelopes, not measured electricity tariffs, technical solar potential or demand forecasts. The park strategy overlaps, so its market is not added. Other industrial processing is a plausible capability adjacency with no revenue included.
Secondary strategy and decisive tests
Park-contracted shared solar sells accepted energy to the authorised park utility, which continues supplying and billing tenants. The developer would combine suitable land or roofs only where network studies support it, obtain rights and finance, then build, meter and maintain. Contractors seek paid work; lenders seek a bankable buyer; the park must retain a saving without losing supply reliability. Aggregation might give larger single awards, but concentrates bargaining power and can add wiring and permissions costs. It is not a guarantee of round-the-clock solar supply or permission for tenant-to-tenant trading. [4][10][11]
The same capital illustration applies before any park margin, network charges or added site costs. At the high-rate/high-price case, only about Rp120 per accepted kWh remains before extras; a wholesale discount could consume it. Acquisition requires direct board/procurement access and costly site/legal diligence. No profitable wholesale price or partner commitment is established. A capable utility could instead own the system or choose its established developer.
Investigate the featured repeat-site business first: its initial question can be answered with one authorised 10–20 MWp proposal and matched priced bids, before buying assets. This is a business test. Participants would be the owner/park buyer, network engineer, qualified contractor and project financier; none is committed. Compare incumbent financed delivery, owner-built solar and existing power at avoidable cost on the same accepted-output and reliability scope. Measure authority, earliest credible start, buyer discounted saving, accepted output and developer return after actual acquisition and integration costs. Seek a conditional purchase commitment. Falsify the proposition if there is no authorised uncommitted site, no valued delivery gain or no price yielding both buyer saving and developer profit.
For Park-contracted shared solar, ask one authorised utility for a priced conditional purchase agreement for energy when available, reviewed by counsel, engineers and financiers. Compare utility ownership and an existing developer’s offer. Measure accepted output, net tariff, network work, buyer saving and developer return. Falsify it if there is no viable authorised buyer, no simultaneous saving and return, or only a purchase requiring an uneconomically guaranteed output. The park route can aggregate larger single contracts, but there is no evidence that its national potential exceeds the featured route: they pursue overlapping projects.
Routes considered and evidence still needed
- Pooled dispatch management and retrofit controllers contribute a compatibility study to the featured service; no measured control failure or saleable output gain supports a separate software business.
- Modular quick commissioning and plug-and-play systems merge into repeat-site delivery; required site studies and financing cannot be deleted.
- Output-linked billing and production-aligned payments contribute auditable settlement and negotiated shutdown terms. Performance billing already exists. A minimum payment protects developer receipts and leaves risk with the buyer; software cannot erase capital costs.
- Managed delivery and finance coordination can support the featured developer, but guarantees and finance premiums are costs to price, not automatic savings.
- Distributed-site aggregation contributes to the park strategy only where its extra cables, rights and diligence make economic sense.
- Local procurement with staggered capital calls lacks a demonstrated advantage over existing purchase and flexible-finance offers; reopen if a priced comparison establishes one.
- An internal trading platform adds fees and metering without established incremental value over central park purchasing; reopen on actual valuable surplus trades and verified authority, not an assumed prohibition.
Observed: a contracted financed-solar model, further project financing, commercial payment choices and physical/site constraints. Inferred: repetition could reduce development work. Unknown: a comparative delivery advantage, current buyer avoidable costs, usable output, uncommitted authorised sites and a fully costed profitable tariff. The existing suppliers may already perform the proposed work efficiently. The publication’s three bounded repeat searches found no matching post; that is not proof of exhaustive absence.
