The report identifies that the typical LCOE for well-run minigrids is at least $0.60 per kWh, which is too expensive for widespread use. It proposes six cost-reduction pathways—hardware standardization, demand stimulation, customer engagement, clustered project development, low-cost financing, and regulatory reform—to bring the LCOE down to $0.25 per kWh by 2020. The document also provides an investment roadmap to transition from grant funding to commercial debt.

The document identifies a critical gap in India's goal to achieve 40 GW of rooftop solar by 2022, noting that as of March 2018, capacity was only ~2.53 GW. It argues that while the Commercial and Industrial (C&I) segment is growing, expansion is limited to high-credit entities, leaving MSMEs underserved due to a lack of credit history and collateral. To address this, the authors propose a Credit Guarantee Mechanism (CGM) as a bilateral loss-sharing agreement between a trust fund and lending institutions. This mechanism would provide a Liquidity Backstop Pool for payment delays and a Partial Loss Guarantee Pool for defaults, effectively reducing the risk for banks lending to Renewable Energy Service Companies (RESCOs). The study estimates that $1 million in donor grant capital could mobilize $14 million in capital and install 18 MW of capacity.

The Battery Subscription Facility is a special purpose vehicle (SPV) designed to lower the high upfront cost of electric buses in India—which are 1.5 to 2 times more expensive than diesel buses—by providing batteries on a subscription basis. By separating the cost of the battery from the vehicle, the facility aims to reduce upfront capital expenditures for bus operators by 40-50%. The implementation is structured in three phases: a pilot phase (10-30 buses), a catalytic phase (1,000 buses), and a scale-up phase (up to 10,000 buses). The model relies on a tripartite agreement between the bus operator, the Facility, and a local financial institution (LFI), with long-term debt (8-10 years) sourced from development finance institutions (DFIs) to match the cash flow profile of electric bus operations. The facility primarily targets the corporate bus segment to minimize counterparty risk and simplify charging infrastructure installation.

The Rooftop Solar Accelerator (RSA), implemented by Peacock Solar, aims to overcome barriers to residential solar adoption in India—such as high upfront costs and operational inefficiencies—by using a solar leasing model, standardized product offerings, and advanced data analytics. The instrument targets smaller Indian cities, starting with a test phase in Kota, and seeks a mix of commercial debt, equity, and philanthropic capital to scale. If replicated, the model could potentially mobilize US$ 380 million and abate 640,000 tons of CO2 by 2022.

The Smallholder Forestry Vehicle (SFV) is a proposed financial instrument designed to scale smallholder forestry in Africa by aggregating tree production contracts into a Special Purpose Vehicle (SPV). By separating the high-risk establishment and harvest phases from the lower-risk growth phase, the SFV aims to lower the cost of capital and attract institutional investors. A proof-of-concept facility targeting US$ 35 million in coastal Kenya is proposed to restore 5,000 hectares of degraded land and provide climate-resilient savings to over 16,000 households. The analysis suggests that with concessional debt and first-loss equity, the vehicle can achieve a gross internal rate of return (IRR) of 11.1%. Long-term goals include expanding into Greater East Africa and mobilizing up to US$ 8.5 billion in initial investment to meet regional land restoration targets.

The Smallholder Forestry Vehicle is a proposed financial instrument designed to enable forestry companies in Africa to access long-term, low-cost finance by aggregating smallholder tree production contracts into a Special Purpose Vehicle (SPV). By separating the high-risk establishment and harvest phases from the lower-risk growth phase, the vehicle aims to attract institutional investors, including pension funds and impact investors. A proof-of-concept facility targeting US$ 35 million in coastal Kenya is proposed to demonstrate risk-adjusted returns and climate resilience benefits, such as land restoration and diversified income for farmers. The analysis suggests that the instrument can leverage significant private capital and be replicated across other East African nations to meet land restoration targets.

The Socio-Climate Benefits Fund (SCBF) is a proposed investment vehicle designed to combat small-scale deforestation in the Brazilian Amazon. It operates by funding a 'New Company' that provides upfront capital, technical training, and market access to smallholders who implement sustainable agroforestry systems (SAFs) on their land. The model utilizes a vertical integration approach, similar to poultry or swine supply chains, where the New Company and smallholders co-own the harvest. The initial pilot targets the state of Acre, aiming to restore 12,000 hectares of forest and engage up to 3,000 properties over a decade. The fund seeks a mix of grants, concessional debt, and equity to overcome barriers such as lack of long-term finance and market access for small-scale farmers.

The report argues that India's 40 GW rooftop solar target by 2022 requires an estimated USD 39 billion in investment, but growth is hindered by high upfront costs and limited access to debt capital. It proposes a Solar Municipal Bond (SMB) model where municipal entities act as finance aggregators, issuing bonds to provide low-cost, long-term debt to private developers via capital lease arrangements. This model could reduce the levelized cost of electricity (LCOE) for rooftop solar by up to 12%. Case studies in Surat and New Delhi suggest that while the model is promising, significant barriers exist, including a lack of statutory mandates for municipalities to promote power generation and the need for high credit ratings to attract institutional investors.

It proposes a Solar Municipal Bond (SMB) model where municipal entities act as finance aggregators, issuing bonds to provide low-cost, long-term debt to private developers via capital lease arrangements. This model could reduce rooftop solar costs by up to 12%. Case studies in Surat and New Delhi indicate that SMBs could make rooftop solar more competitive against grid tariffs, particularly for commercial and industrial sectors. However, significant barriers exist, including the lack of a statutory mandate for municipalities to promote power generation and SEBI regulations requiring a 20% equity contribution.

The document introduces a financial model developed by the Intergovernmental Forum on Mining, Minerals, Metals and Metals (IGF) to help governments quantify the impact of tax incentives on public revenues. It emphasizes that conventional cost estimates often overlook 'behavioral responses'—actions taken by investors to maximize financial gains from incentives—which can significantly increase revenue losses. The guide outlines a four-step framework: estimating reference revenues, calculating direct costs, estimating behavioral costs, and determining the total revenue loss. It provides specific examples of behavioral risks, such as 'high-grading' (écrémage) in response to tax holidays, excessive interest deductions following withholding tax exemptions, and under-invoicing of ore sales under progressive royalty schemes. The document also advocates for the use of scenario modeling and sensitivity analysis to test the robustness of these estimates and determine if incentives are effectively targeted to support marginal investments.

The document argues that tax incentives in the mining sector are often inefficient and ineffective because mineral resources are immobile, making them less responsive to fiscal lures than other investments. It details how specific incentives—such as temporary tax holidays, withholding tax relief, and cost-based incentives—can trigger 'behavioral responses' like high-grading (écrémage) and abusive transfer pricing, which further erode the tax base. The guide provides a step-by-step methodology for modeling the budgetary cost of these incentives and offers specific policy recommendations to protect national revenues, including the use of accelerated depreciation over tax holidays and the implementation of 'bracket' rather than 'class' progressive royalties.

The briefing proposes the use of Solar Investment Trusts (SEITs), structured as Infrastructure Investment Trusts (InvITs), to address financing barriers for small-scale rooftop solar projects in India. By pooling assets, SEITs aim to attract institutional investors, reduce the cost of equity by 300-350 basis points, and potentially mobilize USD 1 billion for the rooftop solar sector within five years. However, the document identifies significant barriers to immediate implementation, including SEBI's minimum asset value requirement of INR 500 crore and strict leverage limits of 49%, which currently exceed the capacity of even the largest Indian rooftop solar developers.

Sustainable Energy Bonds (SEBs) are proposed as a mechanism to bridge the debt financing gap for small-scale sustainable energy projects in India. By aggregating small projects through a Non-Banking Finance Company (NBFC), SEBs reduce transaction costs and provide standardized impact reporting to attract impact investors. The analysis suggests that initial issuances, such as a proposed USD 5 million pilot by cKers Finance, require approximately 4% in public finance support—covering credit enhancement and monitoring, reporting, and verification (MRV) costs—to maintain competitive lending rates of around 10% for project developers.

The Matchmaker Service is a two-part instrument consisting of a subscription-based platform to match investors with city-level climate projects and a project preparation facility to improve project bankability. It specifically targets the financing gap for urban climate infrastructure in India, where municipalities often lack the capacity to create commercially viable projects and the creditworthiness to attract private capital. The report proposes a pilot project for electric bus fleets in Srinagar, Jammu and Kashmir, utilizing a blended finance model via a Special Purpose Vehicle (SPV) to reduce the high cost of capital associated with private operators.

The Climate Smart Cattle Ranching (CSCR) initiative proposes a 'New Company' to address barriers to sustainable beef production in Brazil, specifically targeting mid-sized ranchers in the Amazon who lack formal land titles. The model uses a blended finance approach—initially through a Participations Investment Fund (FIP) involving grants, concessional debt, and impact equity—to co-invest in pasture restoration and the adoption of Embrapa’s Good Agricultural Practices (GAP). By providing long-term capital (up to 10 years) and continuous technical assistance, the instrument aims to increase productivity from 0.5-0.7 to up to 4 Animal Units per hectare, potentially reducing emissions intensity by 90-95% per kg of beef. The strategy includes a phase-out of concessional capital in favor of commercial investment via a Credits’ Rights Investment Fund (FIDC) once a track record of receivables from deforestation-free beef off-take agreements is established.

The document proposes the Green FIDC, a specialized securitization vehicle that transforms risky greenfield projects into bankable assets for institutional investors. By utilizing a two-stage process—initial development finance followed by refinancing through senior shares in the Brazilian capital markets—the instrument aims to reduce reliance on the Brazilian National Development Bank (BNDES) and lower the cost of capital for renewable energy and energy efficiency initiatives. The analysis highlights two pilot opportunities: a 90 MW solar PV project in Ceará and a municipal street lighting LED retrofit in Rio de Janeiro. Financial modeling suggests the instrument is commercially viable, with the potential to leverage USD 1 billion in investment and avoid 10 million tons of CO2 if scaled.

The briefing presents a business case for applying R-PACE financing to new residential construction to achieve net-zero energy (NZE) goals. It identifies key market barriers—such as high up-front costs and split incentives between builders and buyers—and proposes a policy framework to integrate R-PACE into new builds. RMI's analysis across six U.S. states suggests that NZE homes can be delivered with no additional up-front cost to the buyer, providing annual energy savings that exceed the PACE assessment payments.

The report argues that traditional utility and project finance models are inefficient for renewable energy because they do not align with the specific risk-reward profiles of wind and solar assets. It proposes the Clean Energy Investment Trust (CEIT), a liquid, exchange-traded vehicle targeting liability-hedging investors (such as pension funds and insurance companies) by offering investment-grade, bond-like returns. To achieve this, the CEIT unbundles project cashflows into four streams: construction finance, predictable contracted cashflows (the CEIT core), volatile 'surplus' cashflows, and 'tail' cashflows occurring after the fixed-price regime expires. By using risk-mitigation tools—including diversification of 5-10 assets, conservative P75-P95 production estimates, and long-term O&M contracts—the model claims it can reduce the cost of wind-generated electricity by 15-17%.

The document outlines the financial and environmental modeling for a proposed USD 100 million equity fund designed to scale up renewable energy projects. It details the use of an option mechanism to make early-stage development more attractive to investors, projecting that public finance could mobilize significant private capital and abate substantial CO2 emissions. It also compares RESF to various other clean energy funds and technical assistance initiatives across Africa, Asia, and Latin America.

The report finds that finance flows to decentralized energy access enterprises are significantly lower than required to meet national targets, with a particularly severe gap in the clean cooking sector. While some markets like Kenya are dynamic due to PAYGO models and mobile money, others like Ethiopia and Myanmar struggle with severe foreign exchange restrictions and a heavy reliance on grants. Across all five countries, high collateral requirements from banks and currency volatility are primary barriers to obtaining debt. The study estimates that annual finance needs for Tiers 1-3 energy access in these five countries are approximately $3.97 billion, while the total estimated cost for meeting clean cooking targets through 2030 across four of the countries is $18.44 billion per year.
