The report outlines a financing facility to address debt capital shortages for India's rooftop solar sector, specifically targeting commercial and industrial segments. It proposes a mechanism to bundle small projects into a warehouse line of credit, which is then refinanced via asset-backed securities (ABS) to attract institutional investors. The facility aims to lower debt costs by 0.5-3.5% and add 500MW of capacity by 2022.

The National Energy Transition Strategy (NETS) for Saint Lucia identifies an optimal energy portfolio consisting of solar, wind, energy storage, energy efficiency, and existing diesel generation. This combination is projected to reduce diesel expenditures by 42% and carbon emissions by 40% by 2025. The report emphasizes that utility ownership generally leads to lower customer rates and that energy efficiency is the most cost-effective resource for minimizing system costs. While geothermal energy offers significant base-load potential, its viability depends on concessional financing and successful exploration. The strategy also highlights the need for regulatory reform, specifically decoupling utility revenues from sales to incentivize energy efficiency and avoiding 'rate shock' associated with certain independent power producer (IPP) arrangements.

The report analyzes the third party financing model for rooftop solar in India, where developers install and own systems and sell power to consumers via long-term agreements. While the model is financially viable in most states for industrial and commercial segments—often achieving grid parity without incentives—its growth is hindered by limited debt finance, consumer credit risk, and inconsistent net metering implementation. The report suggests policy interventions such as training bank officials, involving DISCOMs in power purchase agreements, and creating specialized dispute courts, alongside financial instruments like peer-to-peer lending platforms and green bond securitization.

The report finds that while Rajasthan has successfully increased its generation capacity and improved reliability, its distribution companies (discoms) face a severe financial crisis. Discoms are unable to recover operating costs through tariffs, leading to mounting debt and a heavy reliance on state government fiscal transfers. Although renewable energy capacity has grown rapidly, investment gaps in transmission and distribution (T&D) infrastructure hinder the integration of these sources and the achievement of comprehensive rural electrification.

The document examines the US YieldCo model, which raised $23 billion by mid-2015 but saw valuations crash due to aggressive growth targets that introduced market-correlated risks. It argues that by prioritizing sponsor objectives—such as recycling capital and monetizing undeveloped pipelines—these vehicles sacrificed the low-risk, bond-like characteristics of renewable assets. The authors propose a 'Clean Energy Investment Trust' (CEIT) consisting of a closed set of assets with no growth expectations, which they argue would better align with the needs of institutional investors and lower the overall cost of renewable energy deployment.

The report identifies off-taker risk, primarily driven by the poor financial state of public sector electricity distribution companies (DISCOMs), as a major barrier to foreign investment in India's renewable energy sector. It suggests that existing payment security mechanisms are inadequate and lack transparency. Using a new framework based on credit and financial guarantees, the author estimates that a mechanism for a 750MW solar project should be INR 4160 million, which is nearly three times the size of the existing mechanism for JNNSM Phase 2, Batch 1. The document recommends a more transparent framework to demonstrate risk coverage and long-term structural reforms for DISCOMs.

The paper argues that off-taker risk—specifically the risk of delayed payments from state-level public sector electricity distribution companies (DISCOMs)—deters foreign investment in India's renewable energy sector. While the Indian government has implemented payment security mechanisms (PSMs) under the Jawaharlal National Solar Mission (JNNSM), the authors contend these lack transparency and are inadequate in size. To address this, the authors develop a framework based on credit and financial guarantees, utilizing probability of default (PD), exposure at default (EAD), and recovery after default (RAD). Applying this framework to the Solar Energy Corporation of India (SECI) for JNNSM Phase 2, Batch 1, the authors estimate a required PSM size of INR 4160 million (INR 5.55 million/MW), which is more than 2.5 times the size of the existing INR 170 crore facility. The document concludes that transparent, adequately sized PSMs are essential to mobilize foreign capital and efficiently use public funds.

The Boulder Valley School District (BVSD) in Colorado is implementing a comprehensive energy strategy to reach net-zero energy and an 80 percent reduction in greenhouse gases by 2050. Supported by a $576.5 million bond approved in 2014, the district is utilizing deep retrofits, retrocommissioning, and new construction across its portfolio of over 50 buildings. In partnership with RMI, BVSD has adopted an integrative design process and a Sustainable Energy Plan (SEP) to reduce energy use intensity (EUI) from an average of 65 to less than 30 kBtu/SF. The initiative aims to save nearly $500,000 annually in utility bills and serve as a model for other U.S. school districts.

The report examines the South African utility-scale renewable energy market, primarily driven by the Renewable Energy Independent Power Producer Procurement Programme (REIPPPP). It details the growth of wind and solar PV, the impact of local content requirements, and the role of the Western Cape as a greentech hub. It also identifies expansion opportunities within the SADC region and other African nations, while noting infrastructure constraints at Eskom.

The paper examines two contrasting models for financing clean infrastructure in middle-income countries: Brazil's centralized approach led by the national development bank (BNDES) and India's decentralized system involving various public and private institutions. Through case studies of wind energy projects, the authors find that despite their structural differences, both systems are dominated by public financing and struggle with a lack of true non-recourse project finance and limited financial innovation. Brazil's model effectively supports national industrial goals through local content requirements and centralized auctions but faces risks of crowding out private investment and governance issues. India's model allows for more diverse participants and smoother integration of international development finance but suffers from higher system costs, uneven investment across sectors, and significant revenue risks due to the poor financial health of state-owned power distribution companies (discoms). The report concludes that the effectiveness of these models is heavily dependent on complementary regulatory and policy frameworks rather than the financing structure alone.

The RMI Innovation Center was constructed using an Integrative Project Delivery (IPD) contracting model to foster collaboration and cost-effectiveness. The building is designed for extreme energy efficiency in a cold climate, targeting an energy use intensity of 17.2 kBtu/ft2. RMI utilized a multi-party agreement to share risks and rewards among project participants and established an operational incentive pool based on avoided energy costs to ensure performance after occupancy.

The document outlines a framework for sustainable finance based on five transaction elements: financier, principal, expenditure, agreement (source of capital), and agreement (use of capital). It identifies three primary barriers to capital flow—risk/return, information, and scale—and suggests that these can be addressed through both policy and non-policy strategies. Applying this framework to case studies, the report finds that residential solar in the U.S. is primarily hindered by consumer-side barriers and lack of standardization, whereas electric vehicle (EV) adoption is stymied by limited financier demand for infrastructure-appropriate financial instruments.

Microsoft contracted for 285 MW of wind energy from two off-site projects, which were enabled by long-term off-take agreements. The company's data center energy group pursued these power purchase agreements (PPAs) to hedge against energy price fluctuations and reduce long-term costs, noting that powering a data center can cost twice as much as its construction. The process was supported by a corporate commitment to carbon neutrality established in 2012, which included an internal carbon fee and a "carbon neutral council." Microsoft accelerated its procurement timeline—completing the first deal in six months and the second in six weeks—by utilizing a dedicated centralized energy team, external partners, and explicit executive support.

The SE4All Finance Committee report identifies a global annual investment need of over $1 trillion to meet 2030 sustainable energy goals, noting a significant funding gap of $654-862 billion. It argues that while capital is abundant, it is not automatically allocated to sustainable energy due to perceived risks, particularly in emerging markets. The report proposes four key investment themes—green bonds, DFI risk-sharing structures, new insurance solutions, and aggregation models—which could collectively catalyze an additional $120 billion in annual investment by 2020. It emphasizes the need for improved project preparation, the use of dedicated project preparation funds, and the strengthening of the governance and creditworthiness of power utilities in developing countries to create a pipeline of bankable projects.

The Olkaria III project, a 110 MW binary geothermal plant, is the first privately funded geothermal project in Africa. It succeeded by utilizing a phased expansion strategy and a mix of public and private financing. Key enablers included the Kenyan government's provision of exploratory data and wells, a 20-year power purchase agreement (PPA) with USD-pegged tariffs, and long-term, low-cost debt from Development Finance Institutions (DFIs). The project achieved a levelized cost of electricity (LCOE) 13% lower than the average for similar Kenyan projects, demonstrating that public-private models can be more cost-effective than purely public ones.

The paper argues that high currency hedging costs in India negate the benefits of cheaper foreign loans, increasing renewable energy costs by 30% compared to the US. Using a stochastic model, the authors find that a government-sponsored FXHF could provide a 10-year currency hedge at an expected cost of 3.5 percentage points, which is 50% lower than market rates. Such a facility could reduce the delivered cost of renewable energy by up to 19% and government support costs by up to 54%, provided the government manages extreme currency risks. To achieve a credit rating equivalent to India's sovereign rating of BBB-, the paper estimates a cumulative capital buffer of approximately 30% of the underlying loan would be required.

The report finds that while renewable energy auctions are generally cost-effective and fair in project allocation, they often suffer from low deployment due to poor risk management. By analyzing 20 global auctions, the study identifies that project risks (such as transmission and land acquisition) have a greater negative impact on deployment than auction-specific risks. The authors recommend a 'controlled environment' for introducing wind energy auctions in India, including pre-identified sites and resource assessments, alongside the use of strong penalties for non-commissioning and payment guarantee mechanisms to ensure financial viability.

The Corporate Renewable Energy Buyers’ Principles, developed by large US businesses with support from WWF and WRI, identify six key priorities to help companies meet their public climate and energy goals. These include seeking greater choice in procurement options, cost competitiveness with traditional energy, and access to long-term, fixed-price contracts. The principles emphasize the desire for 'additionality'—driving new renewable power generation—and a preference for bundled energy and Renewable Energy Credits (RECs) over unbundled ones. The signatories also call for simplified third-party financing, the prevention of double-counting of emission benefits, and increased collaboration with utilities and regulators to expand procurement choices for both new and existing operations.

Kaiser Permanente partnered with NextEra Energy Resources to procure 110 MW of solar and 43 MW of wind power, aiming to meet 50% of its California electricity consumption through renewable sources. The organization views climate change as a health issue and set a 2012 target to reduce greenhouse gas emissions by 30% below 2008 levels by 2020. The deal is expected to avoid 215,000 metric tons of greenhouse gas emissions in California, equivalent to removing over 45,000 cars from the roads. The case study highlights the importance of assembling a cross-functional team, balancing economic feasibility with mission-driven goals, and managing internal stakeholder engagement to successfully execute complex off-site renewable energy transactions.

The document outlines the systemic shifts required to integrate low-carbon energy, arguing that traditional power plant financing and grid structures are ill-suited for renewables. It proposes new financing models like YieldCos and Muni Finance to lower costs, emphasizes the need for regionally integrated transmission and updated balancing markets to manage variability, and discusses the disruptive impact of distributed generation and demand-side flexibility on traditional utility models.
