Energy transition: who takes the first loss?
Wind, solar and public money: Monsoon, Verdant and Citicore illustrate loss allocation, guarantees and the economic cost of financial support.

A wind project needs financing long before it delivers its first electricity. Before it is built, however, it must pass another test: persuading several investors that they will be paid, in a particular order, through years when wind, grid capacity or revenue may fall short. The energy transition is negotiated through that payment order too. A small pool of public capital may be enough to make the rest of the financing acceptable. Its size tells part of the story; the rights it gives up tell another.
On 28 October 2026, the International Energy Agency and Convergence published a study of blended finance for renewable energy in Southeast Asia. Their central estimate is USD 3.7 billion in cumulative international public support over 2026–2035, for selected sectors in Indonesia, the Philippines and Vietnam. The amount is conditional on the national pledges assumed in the scenario. The report examines a way to make projects financeable: using concessional capital to absorb, share or reduce particular risks. This capital accepts more favourable terms for the project than commercial financiers would offer, through lower returns, longer waits or greater risk. R01
The subject deserves more than a contest between generous public money and cautious private investors. Financing can open a market, build useful infrastructure and fairly reward those taking risk. It can also provide excessively costly protection to a project that would have found lenders anyway. The difference between those outcomes lies in the comparison with financing without support, the price of the protection and the distribution of the benefits it creates.
First loss is a governance choice: it identifies who accepts losses before others, in return for something. This investigation follows that exchange through three transactions, a fund with several levels of risk and two reproducible numerical examples. It also examines a less visible concession: receiving money back later, at a lower return.
Evidence cutoff: the afternoon of 29 October 2026, Europe/Paris. Transactions are described through announcements and public documents; complete contracts were unavailable in the material collected. The teaching calculations are entirely fictional. Dollars are US dollars; Vietnamese amounts remain in dong where that currency matters to the mechanism.
A ten-year estimate of USD 3.7 billion
The IEA estimate covers four groups: rooftop solar, decentralised solutions, batteries and offshore wind. It examines ten combinations of technologies and countries. Vietnam is excluded from the decentralised-solutions assessment because grid access is almost universal; Indonesian offshore wind is excluded because its market and regulatory framework remain at an early stage. Detailed electricity transmission and distribution needs also fall outside this assessment. R01
The horizon spans ten years. The unit is 2025 US dollars at market exchange rates. The Announced Pledges Scenario, or APS, assumes that announced commitments are fulfilled completely and on time. The USD 3.7 billion therefore expresses estimated international public financing need in a conditional future. Its uses include several forms of intervention, only some of which would involve blended structures. Budget commitments and actual payments will require separate tracking. R01
The breakdown gives an initial indication of the work involved. The report identifies approximately USD 100 million for rooftop solar, more than USD 200 million for decentralised solutions, USD 1.1 billion for batteries and nearly USD 2.3 billion for offshore wind. These rounded benchmarks convey orders of magnitude. Their presentation preserves the source’s approximations and the boundaries of its assessment. R01
A dollar spent preparing an offshore project may pay for studies or contract design. A dollar directed towards electrifying a remote area may sustain a service whose commercial revenue remains low. A dollar placed beneath a private tranche may improve its protection against losses. Adding these interventions is useful when considering a funding envelope; evaluating them requires recovering their individual purposes.
The first governance question emerges here. A financing target can easily become a target for signed volume. Public value, however, depends on the constraint removed: securing a grid connection, more predictable revenue, debt maturity compatible with the asset’s life, or an accessible service. Every expenditure should be linked to an outcome that the other available instruments would have had greater difficulty achieving.
The regional scope also recalls the physical dimension of investment. The IEA’s Energy Outlook 2026 considers generation, grids, energy security and end uses together. Our interpretation follows from that: an additional wind or solar farm gains value when the system can absorb its electricity. Preparing the grid and the contracts therefore affects the return on capital invested in equipment. B01
The cost of capital depends on contracts
An energy project converts spending today into revenue tomorrow. The cost of capital summarises the return required by those financing that wait, given the risks they face. Lowering that required return may allow a project to be built with a lower electricity tariff, or make longer debt possible. How that advantage is shared then depends on competition among developers and their contracts with buyers.
Wind and sunlight are the beginning of the chain. An installation needs permits, construction, a grid connection and maintenance. Electricity must be deliverable, billed and paid for. A borrower servicing dollar debt with local-currency revenue adds foreign-exchange exposure. Lenders therefore examine the quality of contractual commitments as closely as the promised technical performance. The report explicitly distinguishes revenue, regulatory, project-maturity and financing constraints. R01
An IEA study published in October 2025, based on a 2024 survey, had already identified the burden of financing costs and the shortage of sufficiently prepared projects. It also noted competition among financiers for some available deals. That observation matters: abundant announced capital can coexist with a shortage of projects able to receive it. The conditions observed in 2024 illuminate the mechanism; updating them would require a new survey. B02
Blended finance seeks a point of intervention along this chain. It can absorb a layer of losses, guarantee a payment, finance development or accept later repayment. Its effectiveness depends on an accurate diagnosis. A bank constrained by the concentration of its loans to a single electricity buyer faces a different problem from a project lacking a revenue contract.
That distinction raises a political question. The provider of public protection chooses which risks it considers acceptable to carry and the terms on which investors will be rewarded. Negotiation concerns both access to financing and the distribution of its value. When support reduces the cost of debt, the benefit may reach consumers, the developer or lenders in proportions that need to be established. The “transition” label describes the intended purpose; contractual cash flows allow us to examine its delivery.
First loss is determined by the ranking of claims
Consider an entirely fictional USD 100 million structure. It comprises USD 10 million in public capital, USD 20 million in private equity and USD 70 million in senior debt. Here, “senior” means the tranche protected by the other two: they absorb losses before it does. Assume a total loss of USD 25 million on the initial capital, with no interest, fees or subsequent recoveries.
In the first structure, public capital takes the first loss: all USD 10 million is lost. Private equity absorbs the next USD 15 million. Senior debt retains its principal. In the second structure, the USD 20 million in private equity absorbs losses ahead of the public capital. The public provider then loses USD 5 million; the senior tranche remains protected. With the same total loss, the contract shifts USD 5 million of the burden between the public provider and private investors.
The USD 70 million senior tranche has the same total USD 30 million cushion in both structures. Its protection against the capital loss used in this example therefore remains identical, regardless of the internal ranking of the first two tranches. The beneficiary of the concession becomes tangible: placing public capital ahead of private equity in the loss order improves the latter’s position here. This finding depends on the example’s simplified rules; a real transaction may have different interest provisions, security, guarantees and payment schedules.
The calculator below lets readers vary the capital, the first two tranches and the total loss. It calculates a conditional allocation: if this loss occurs, this is how it is shared. Establishing the expected cost of an intervention would also require probabilities for the different outcomes, payment timing and recoveries. None of these empirical parameters is assigned to the transactions examined here.
l0g / ENERGY TRANSITION / LOCAL CALCULATOR
Compare two orders for absorbing a loss
Fictional example: $100 million of capital, including 10% public capital, 20% private equity and 70% senior debt. A loss of 25% is allocated in two different orders.
Change the four assumptions
A: public capital absorbs losses first
| Tranche | Capital | Loss | Remaining |
|---|---|---|---|
| Public capital | |||
| Private equity | |||
| Senior debt |
B: private equity absorbs losses first
| Tranche | Capital | Loss | Remaining |
|---|---|---|---|
| Public capital | |||
| Private equity | |||
| Senior debt |
- Total loss in each structure
- Total remaining in each structure
- Additional public loss in structure A
Method and limits
Losses are allocated in order until each tranche’s initial capital is exhausted. A: public capital, private equity, senior debt. B: private equity, public capital, senior debt. Senior debt absorbs losses after both other tranches in each structure.
This is the allocation if the stated loss occurs. It is neither an expected loss nor a fiscal-cost estimate. The exercise excludes loss probabilities, interest, fees, guarantees, recoveries and payment timing. The inputs describe none of the transactions discussed in this article.
Calculations use exact integer units of one millionth of a dollar. Each displayed amount is rounded independently to cents; displayed rows may therefore differ by a cent when added.
Calculations run in this page. Inputs stay in memory while it is open.
The Green Investments Partnership (GIP) fund, managed by Pentagreen, provides a real architecture to which this teaching example can be related. The IEA–Convergence report describes a catalytic junior tranche, followed by mezzanine and senior tranches remunerated on commercial terms appropriate to their risk. On 20 May 2026, Pentagreen announced USD 800 million in committed capital at the second close. The documents establish this general ranking without disclosing the full size or economic terms of each tranche. Our example’s 10/20/70 proportions therefore remain fictional. R01 C03
The provider taking the first risk also deserves to be named. It may be a government, a multilateral bank, a development fund or a foundation. For FAST-P, the broader Asian blended-finance programme to which GIP belongs, Singapore announced up to USD 500 million in concessional funding, with a matching objective involving other providers. That ceiling covers FAST-P as a whole. The precise amount allocated to GIP’s first-loss position requires its own documentation. C05
A return forgone is also a form of support
A transaction may repay all its principal and still have received substantial economic support. Money tied up has value over time. A reduced interest rate, long maturity or payment deferral transfers some of that value to the project and its other financiers.
Here is a second entirely fictional example. A lender advances USD 10 million today. It receives an annual 2% coupon, or USD 200,000 a year, for ten years; principal is repaid at the end of year ten. For this calculation alone, choose a 7% discount rate. Discounting expresses each future payment in today’s value using that reference rate.
The ten coupons and final repayment are then worth USD 6.49 million today, after rounding. The difference from the USD 10 million advanced is USD 3.51 million, or approximately 35.12% of principal. Yet the loan will have returned its USD 10 million and paid USD 2 million in coupons over time. The difference comes from the value assigned to waiting. The figure and its expandable data give the annual cash flows and calculation; the simulator lets readers change the loss-allocation assumptions.
Data and calculations
Fictional example: $10m principal, 2% coupons at each year-end for ten years, principal repaid at the end of year 10, chosen discount rate of 7%. Each cash flow is divided by (1 + 0.07) raised to its year number. Amounts below are rounded to cents.
| Measure | USD |
|---|---|
| Capital paid today | 10,000,000 |
| Present value of principal repayment | 5,083,492.92 |
| Present value of ten coupons | 1,404,716.31 |
| Total present value received | 6,488,209.23 |
| Difference from capital paid | 3,511,790.77 |
The reference rate is decisive. We set it at 7% to make the mechanism visible; it comes from none of the transactions analysed. The result is a present-value difference in a teaching model. Using it as an actual fiscal cost, guarantee premium or official grant equivalent would require further methodology and data.
The International Finance Corporation (IFC), the World Bank Group institution financing the private sector, describes concessionality as a difference between the offered price and a reference price, established from market information, a model or negotiation, depending on the case. Its disclosures may express this estimated subsidy as a share of project cost. A public-capital share, a first-loss tranche and concessionality measured in this way therefore answer three different calculations. The reference price should accompany any percentage presented to the public. G05
Timing also changes payment capacity. If a lender accepts later principal repayment, early revenue can service other debts. This concession is particularly useful when operating cash flows build gradually. It exposes the patient lender to a longer wait and leaves more cash available during the early years. The Monsoon case allows us to observe that logic in an arranger’s account.
Monsoon: protecting repayment when electricity cannot be delivered
The Monsoon wind farm in Laos sells its electricity to Vietnam. It offers a regional, cross-border illustration beyond the study’s strict three-country scope. On 1 March 2023, the Asian Development Bank, or ADB, announced a signed USD 692.55 million package for the 600 MW wind farm. In a release dated 28 August 2025, contractor POWERCHINA dates full commercial operation to 22 August 2025. C01 C12
The package comprises a USD 100 million A loan provided directly by ADB, a USD 150 million B loan syndicated to other financiers, USD 50 million in concessional financing, USD 382.55 million in parallel loans and a USD 10 million grant. These headings describe the instruments within the announced financing. The parallel loans bring together different kinds of institutions; their entire amount cannot serve as a measure of private capital. The package also has its own scope, distinct from total project cost including all equity contributions. C01
The function of the USD 10 million grant is particularly instructive. According to ADB’s financing team, it funds a debt-service reserve account. Extreme restrictions on delivery or generation can reduce revenue enough to jeopardise payments to senior creditors. The reserve then provides partial protection under the mechanism’s terms. C11
The causal chain is clear: less deliverable electricity means less revenue, then pressure on debt payments; the reserve supplies resources for debt service in the specified circumstances. The public intervention has a defined purpose. Its effectiveness depends on the triggers, the amount available and the exposure it enables lenders to accept. Construction risk, technical risk and other sources of difficulty require their own protection.
The USD 50 million in concessional financing serves additional functions. In a May 2023 interview, ADB explains that part of the financing carries a reduced interest rate and repayments pushed towards the end of the loan period. This arrangement improves debt-service coverage, particularly during the life of the commercial B loan. The stated senior maturities are seventeen years for the B loan and nineteen years for the parallel loans. The detailed repayment schedule and the allocation across these functions remain unavailable in the collected material. C11
Grouping the grant and concessional loans together as “USD 60 million of first loss” would erase this architecture. The reserve responds to an event; reduced rates and deferrals affect ordinary payments. Following the risk requires preserving those functions throughout the analysis, from the initial advance to possible calls and repayments.
ADB presents these arrangements as decisive in assembling the financing. That assessment comes from the institution that structured the transaction. It documents its reasoning and the announced terms; an independent evaluation would need to examine the competing offers available at the time, the alternatives and the results achieved. Entering operation is an observable milestone. The exact additional investment attributable to each dollar of support remains a more demanding question. C01 C11
Verdant: a guarantee changes whose ability to pay the investor examines
In Vietnam, the Verdant solar platform follows another route. In June 2026, GuarantCo announced a guarantee for a VND 792 billion green-bond programme with a fifteen-year tenor. The announcement envisaged two phases through the end of 2026. In July, FiinRatings described VND 390 billion of initial rated bond issues, a fixed nominal 6.95% coupon and a full, unconditional and irrevocable guarantee. The two amounts retain their separate status: a guaranteed programme and documented initial issues. C06 C07
The mechanism combines revenue from the installations with a second capacity to pay. When an issuer misses a covered payment, the guarantor acts under its undertaking. The detailed note on one bond specifies coverage of principal, interest and accrued interest. Creditors therefore examine the rights attached to the guaranteed bond alongside the developer’s own financial strength. C08
The ratings difference makes that transformation visible. FiinRatings assigns BB+ to the issuers and AAA to the guaranteed bonds. These belong to its Vietnamese national scale, within which the categories must be read. The AAA rating reflects the instrument’s protection as assessed by the agency. The installations retain their operating risks; the payment promise to their creditors benefits from an additional guarantor. C07 C09
Currency also matters. The IEA–Convergence report states that the relevant electricity sales contracts are denominated in dong. Debt in the same currency brings revenue and repayments into alignment, reducing that mismatch for the borrower. Locating the ultimate foreign-exchange risk at the guarantor and its funding providers would require examining their own balance sheets and hedges. R01
Assessing the public commitment requires three quantities. The guarantee ceiling measures contractual exposure. Expected cost depends on possible payments, their likelihood, their timing and recoveries. Cash actually paid out becomes observable when calls occur. Fees received further change the net cost. The IMF’s guide to government guarantees specifically recommends linking their management to exposure limits, fees and the budget treatment of support. G06
The collected Verdant documents leave guarantee fees, complete recourse arrangements and call schedules undisclosed. They establish protection and access to local financing while leaving the protection’s final economic cost open. Several governments support GuarantCo through different arrangements. Bondholders have the guarantor’s undertaking as described in the instrument; treating it as a direct sovereign guarantee from every funding country would add a right these documents do not establish. C06
The policy question therefore extends beyond displaying a large guaranteed face value. It concerns the financing tenor, currency and additional volume secured, followed by how the guarantor is paid for the exposure it accepts. The transaction’s quality lies in those conditions and in the outcomes of the projects financed.
Citicore: capital passes through several layers before reaching construction
The Citicore case shows why financial presentations must preserve corporate structure. In October 2025, Pentagreen announced a USD 55 million loan for the development and construction of solar and storage projects in the Philippines. The targeted portfolio could reach 2 GW of generation and 760 MWh of batteries. These capacities describe an announced deployment programme; the USD 55 million supplies one part of its financing. C04
The IEA–Convergence report places the intervention at holding-company level. A developer must fund studies, preparation costs and part of the contributions required by project companies before all their construction loans are available. A holding-company facility can provide that room to operate. The project banks then finance identified assets and contracts, with their own rights over cash flows and collateral. R01
Risk must therefore be read at two levels. First, the holding-company lender owns a claim whose repayment depends on the borrower and negotiated protections. Then the investors in the fund holding that claim share its portfolio’s results according to their rank. First loss at fund level concerns that second allocation. Understanding who loses when an individual plant encounters difficulty also requires tracing the rights of each company and lender.
This architecture can address a real bottleneck: preparation funding is needed before revenue arrives, and often before more standardised project finance becomes available. The additionality hypothesis then concerns development speed, the number of projects reaching construction or the ability to finance less familiar technologies. Demonstrating it would require tracking drawdowns, permits, construction and refinancing.
The distinction between capital committed to a fund, a loan announced to a company and money used on a construction site is essential. Each represents a useful stage; adding them would count part of the same circuit more than once. GIP’s USD 800 million and Citicore’s USD 55 million have different scopes. Rigorous disclosure should allow readers to move from the financing envelope to the project, then from the project to the service delivered. C03 C04
Mobilisation ratios change with their scope
Using Convergence’s database as of May 2026, the report identifies 54 renewable-energy or battery transactions, representing USD 17.9 billion in transaction volume, across Association of Southeast Asian Nations (ASEAN) countries excluding Singapore. The historical chart is cumulative and starts in 2016 with transactions already recorded. The available documents describe the recorded transactions; an annual disbursement series would require different data. R01 R03
The report offers two revealing ratios. For USD 1 in concessional capital, there is USD 1.40 in private capital. When the numerator also includes commercial capital from development finance institutions and multilateral development banks, the ratio reaches 3.01. The word “commercial” can therefore encompass funds supplied by a public institution when their terms fall within that category. R01
These ratios provide two views of the financing. The second has a broader scope that already includes private capital. Adding them would create double counting. The report does not provide the underlying observations and weighting needed to turn their difference into a precise tranche applicable to each transaction. The figure therefore retains two explicitly defined numerators.
The mobilisation calculation asks a structural question: how much other capital is associated with the recorded support? Financial additionality asks about change: what difference does the support make compared with a situation in which it was absent? One investor may already have been preparing its commitment. Another may have been waiting for a guarantee before accepting a longer tenor. Financing packages of the same size can therefore have very different effects.
Measurement is becoming more disciplined. The joint multilateral-bank methodology framework released on 1 October 2026 distinguishes private-finance generation, mobilisation and catalysation. The methodology for measuring catalysation remains under development. It warns that the indicators can overlap; their amounts must remain separate. Mobilisation is measured at the commitment stage. Rules from the Organisation for Economic Co-operation and Development (OECD) also organise the declared causal link and attribution among institutions to limit double counting. Reporting in accordance with a methodology still needs to be complemented by evaluation of the scenario without support. G04 G03
The most tempting error would be to multiply the USD 3.7 billion of future public financing need by a historical ratio to announce forthcoming private investment. The scopes, instruments and denominators differ: future public support includes uses beyond the concessional capital in recorded transactions. A credible projection would require identified projects, their terms and their prospects of being delivered. The historical ratio supplies a descriptive benchmark; the future portfolio still has to be built.
Useful support must withstand the comparison with no support
The reasoning begins when a developer says its project needs assistance. It knows more than the funding provider about some costs, risks and financing opportunities. Lenders know their own constraints and the return they would accept. The public provider needs enough information to offer useful protection at the best collective cost. This asymmetry makes competition and comparison of alternatives valuable.
The OECD’s 2025 guidance recommends documenting additionality before, during and after the transaction. Modelling and, where suitable, competitive processes can help calibrate concessionality. That requirement leads to a concrete alternative: without support, would the project be delayed, smaller, financed in another currency, offered at a different tariff or abandoned? Each answer creates verifiable elements to track over time. G01
The assessment should also consider alternative public interventions. A guarantee to a generator can improve its borrowing terms; grid spending can open access for several generators. Preparation support can produce projects the market will subsequently finance. A public-service subsidy can suit a service with persistently low profitability. Comparing those routes requires defining the desired outcome before choosing the instrument.
A serious counterpoint appears in the January 2024 assessment of the International Development Association’s (IDA) Private Sector Window by the World Bank Group’s Independent Evaluation Group (IEG). IDA is the World Bank’s fund for the poorest countries. For the operations it examined, IEG found compliance with the minimum-concessionality principle. It also identified underuse of IDA capital where capital was reserved to cover the full exposure. Public money can therefore be deployed with excessive caution, at the cost of useful transactions left unfunded. G02
The same evaluation criticises fragmented financial information on risks, costs and income across World Bank Group entities. Its scope is the IDA window, largely focused on difficult markets, and its period covers fiscal years 2018–2023. It provides a methodological counterpoint based on a still-young portfolio; its findings do not evaluate the three Asian cases in this investigation. Whether these shortcomings persisted in October 2026 was not established by our research. G02
Those conclusions bring two responsibilities together. Public capital needs protection suited to possible losses. It also needs to serve the purpose for which it was entrusted. An excessive reserve ties up resources; protection that is inadequately priced or monitored can concentrate hidden risks. The appropriate calibration depends on the portfolio, dependencies among projects and stress scenarios, beyond the number of guarantee calls observed in the early years.
The right instrument arrives at the right stage
The report’s four technologies occupy different stages of development. A rooftop-solar portfolio may primarily need to aggregate small installations and diversify electricity buyers. A battery needs credible rules for payment for its services. An offshore wind farm requires lengthy preparation and infrastructure compatible with construction and subsequent connection. Financing must follow that maturity. R01
Batteries are revealing. Their value may come from several services: shifting electricity delivery over time, supplying capacity or contributing to system stability. The report emphasises remuneration and contracting frameworks. When accessible revenue remains uncertain, a lower interest rate addresses only part of the problem. Rules that make those services saleable can change financing prospects more fundamentally. R01
For offshore wind, the report prioritises project preparation and market frameworks in the near term, before financial deployment at scale. Concessional support can fund knowledge and procedures that benefit several transactions. Its value is then measured through the quality of the prepared pipeline and the risks actually resolved. Announced megawatts must subsequently pass through permitting, contracting, grid and construction stages. R01
At the other end of the spectrum, some decentralised services for remote communities may remain insufficiently remunerative for a fully commercial model. Lasting support can be justified by energy access and its social benefits. Judging it solely by the private dollars attracted would favour the easiest projects to finance while penalising essential needs. The report recognises this limit to blended finance. R01
An exit from support also needs preparation from the outset. Completion of construction, the emergence of commercial offers or a fall in risk may justify reviewing terms. OECD guidance calls for that trajectory at both project and market level. Support with clear objectives and review dates can evolve with results; assistance renewed automatically may continue rewarding a difficulty long after it has been resolved. G01
Public contracts: risk accepted and value obtained
The investigation leads to a demand for clarity. To understand public protection, a reader should be able to follow one complete sentence: this institution accepts this risk, up to this amount and for this period, in return for this remuneration, to obtain this measurable change. The sentence connects the financial instrument to its justification. It serves a legislator, taxpayer or service user as much as a financier.
Sharing favourable outcomes belongs in the same discussion. When refinancing becomes cheaper, who benefits from the improvement? Does the concession shrink? Does the service become less expensive for users? An equity stake, a fee or a recovery clause can organise different answers. We propose them as subjects for contractual scrutiny; their presence in the cases studied has not been established by the accessible documents.
Monitoring must cross institutional levels. A fund may announce committed capital, a bank its loan, a developer its portfolio and a government its contribution. A common presentation of scope would allow those announcements to be reconciled without adding them together. It would also reveal the currency of risk, covered events, income received by the guarantor and project progress after signing.
Document quality matters even within diagrams. For AC/BIM Wind, the new report contains a reserve box showing USD 82 million, while the adjacent text states USD 5 million. ADB’s primary announcement confirms USD 107 million in financing and an additional USD 5 million grant for environmental and social safeguards. This investigation excludes the inconsistent box and records the discrepancy in its methodology appendix. It is a documentary problem and establishes no irregularity in the transaction. R01 C10
That care has wider significance. A drawing can turn a ceiling into expenditure, a guarantee into a grant or an announced project into an achieved result. Units, dates and calculation assumptions make it possible to trace an announced amount back to the risk actually covered. Making a mechanism accessible requires preserving the distinctions that change the conclusion.
First loss remains a legitimate and sometimes productive choice for public authorities. It can buy time, open a market, lengthen debt or enable infrastructure whose benefits exceed private revenue. Its justification grows stronger when the risk accepted, the return obtained and the additional outcome become verifiable. The real test of blended finance is the quality of that exchange: what transformation does the public obtain for the protection it provides?
Further reading
Financing electricity service continuity raises a related question: who funds useful capacity when ordinary revenues fail to reward it adequately? The analysis of the Bank of Japan’s green loans also shows how a contract’s date and interest rate distribute the benefit of financial support.
