The document argues that public finance is essential to close the 'viability gap' for CSP, as more than 98% of plants built by 2012 required such support. It highlights that while international financial institutions (IFIs) provide critical long-term debt and concessional finance, currency hedging costs often offset these benefits. The authors suggest that deploying 5-15GW of CSP could reduce electricity production costs by 14-44%, potentially making the technology competitive in Morocco and South Africa. Key recommendations include moving away from flat tariffs to remunerate the flexibility provided by thermal storage and transitioning from international to local private debt to ensure long-term sustainability.

The research analyzes wind power contracts under Brazil's PROINFA feed-in tariff scheme, finding that a nonlinear payment structure led wind farms to systematically misreport capacity factors (CFs). By comparing reported and realized CFs for 41 operational projects, the authors demonstrate that reported values clustered around price schedule cutoffs, while realized values did not. This misreporting resulted in wind farms being contracted for 14% more energy than delivered and 12% of first-year payments being over-payments. The paper concludes that a simple 1% interest rate penalty on overpayments would have effectively eliminated the incentive to misreport.

The report identifies that current investor-owned utility and independent power producer models are ill-suited for the low-carbon transition, potentially raising renewable energy costs by up to 20%. It proposes a systemic evolution across five segments: generation (matching financing to risk profiles), transmission (improving renewable integration), market operation (valuing flexibility), distribution (adapting to distributed generation), and customer management (integrating demand response and electric vehicles). The document highlights the emergence of new financing models like YieldCos as a way to provide secure cash flows and lower costs.

The analysis of Brazil's PROINFA program reveals that wind farm developers systematically manipulated capacity factor (FC) estimates to maximize tariffs and contracted energy volumes. This behavior led to a 14% shortfall in expected energy production and 12% overpayments in the first year of operation. The study suggests that a simple 1% interest penalty on excess payments would have eliminated the incentive for such manipulation.

The study analyzes the PROINFA feed-in tariff in Brazil, finding that project developers systematically misreported capacity factors (CFs) due to a tiered price schedule and a lack of penalties for overpayments. This misreporting led to a 14% gap between expected and actual energy production and resulted in 12% of first-year payments being over-payments. The authors suggest that a simple 1% interest rate penalty on overpayments would eliminate this misreporting, making the policy more cost-effective.

The document argues that the Green Climate Fund's Private Sector Facility (PSF) must address specific risk gaps—namely policy and financing risks—to unlock large-scale private capital for climate mitigation and adaptation. It proposes two primary business models: a 'Facilitated Model' acting as a fund-of-funds through intermediaries, and a 'Full-service Model' engaging directly with private actors. The authors emphasize the need for a clear separation between governance and management, suggesting the use of independent due diligence and private sector expertise, potentially through a dedicated Investment Panel, to ensure efficient decision-making and risk management.

This report by the Climate Policy Initiative evaluates federal policies to support India's goal of doubling renewable energy capacity to 55,000 MW by 2017. It compares existing subsidies—such as generation based incentives and viability gap funding—against proposed debt-related policies, concluding that low-cost, long-term debt is the most cost-effective long-term strategy, though it faces shortS short-term budgetary constraints due to high initial capital outlay.

This case study analyzes the 100 MW Rajasthan Sun Technique concentrated solar power (CSP) plant in India, examining how a combination of national policy, foreign public debt, and private risk management enabled the project despite broader failures in India's National Solar Mission (NSM) phase one. While the project demonstrates the viability of linear Fresnel technology and the importance of long-term public financing, it also highlights the 'winner's curse' associated with reverse auctioning schemes that led to underestimated costs and project delays across the sector.

The report identifies that high cost, short tenors, and variable interest rates of debt increase the cost of renewable energy in India by 24-32% compared to the US. It evaluates five recommended instruments to address these barriers: government bonds, infrastructure debt funds (mutual fund model), partial credit guarantees, partial risk guarantees, and exchange rate liquidity facilities. The analysis finds that government bonds offer the highest potential for cost reduction (up to 4.5 percentage points) and tenor increase (up to 10 years), while other instruments like partial credit guarantees can mobilize private capital from pension and insurance funds by enhancing project credit ratings to AA. The report also examines the impact of currency hedging costs, which currently neutralize the advantages of lower-cost foreign debt, and proposes a liquidity facility to mitigate this risk.

The Rajasthan Sun Technique CSP plant in India was made viable through a combination of subsidized power purchase agreements (PPAs), long-maturity debt from international public lenders, and a first-mover strategy by a financially strong private developer. While the project achieved low investment and production costs, the broader National Solar Mission (NSM) phase one faced significant deployment delays due to the 'winner's curse' in reverse auctions, overestimation of solar resources, and financing challenges. The project demonstrated high local content (61-71%) and the benefits of linear Fresnel technology, though it lacked energy storage. Key recommendations for scaling CSP in India include improving auction design, incentivizing storage, and mobilizing local private finance to reduce reliance on foreign public debt.

The report finds that debt-related federal policies, particularly a combination of reduced-cost and extended-tenor debt, are more cost-effective in the long term than existing subsidies like generation-based incentives and viability gap funding. While existing policies often provide better short-term budget efficiency and production incentives, debt-related instruments offer superior subsidy-recovery potential and overall reduction in total subsidy costs. The analysis highlights a trade-off between long-term cost-effectiveness and short-term capital outlay, suggesting that interest subsidies and accelerated depreciation are viable short-term alternatives to current federal support levels.

The report assesses the Risk/Reward Incentive Mechanism (RRIM) implemented by the California Public Utilities Commission (CPUC) in 2007. While the RRIM increased senior management's attention toward energy efficiency and drove the expansion of cost-effective programs like lighting, it struggled to protect ratepayers due to the abandonment of the 'true-up' process. The mechanism's design—characterized by sharp earnings 'cliffs' and retroactive implementation—led to significant regulatory conflict and unpredictable earnings, which limited its value to shareholders. The report concludes that while the RRIM was a valuable experiment, future incentives should be implemented before program design, avoid sharp payment distinctions, and be designed for predictability and repeatability.

The document argues that high debt costs in rapidly emerging economies can increase the cost of utility-scale wind and solar PV projects by 24-32%. It proposes two primary solutions: indexing renewable energy tariffs to foreign currencies to attract lower-cost international capital by mitigating currency hedging costs, and implementing government-backed concessional debt programs to reduce the total support required to make projects viable. The report provides detailed analysis of these mechanisms using India as a primary case study, suggesting that these interventions could lower the cost of renewable energy support by up to 30%.

The report analyzes the current state of concentrated solar power (CSP), noting that while it has potential to supply up to 10% of global energy demand by 2050, it remains expensive and heavily dependent on public support. The authors find that over 98% of total CSP investment to date has required public support. The document outlines a plan to evaluate the effectiveness of public finance through case studies in India and South Africa, expert dialogues, and a final lessons-learned paper. It details various public support mechanisms, including feed-in-tariffs, competitive tenders, reverse auctioning, and concessional loans, while highlighting the specific challenges and opportunities in emerging markets.

The report argues that Brazil can simultaneously increase agricultural production and improve environmental protection by enhancing land-use efficiency. It identifies key barriers to productivity, including limited access to rural credit, insufficient technological diffusion, underdeveloped land leasing markets, and deficient infrastructure. On the protection side, it highlights the need to combat small-scale deforestation in the Amazon, implement the Forest Code on private lands via the Rural Environmental Registry, and extend monitoring to other biomes, particularly the Cerrado. The authors propose a P&P strategy based on systematic monitoring of representative land-use areas and the creation of a public-private consortium to design and test effective policy interventions.

The report proposes a Production and Protection (P&P) strategy for Brazil to reconcile economic growth in agriculture with environmental conservation. It identifies significant within-region productivity gaps in cattle ranching, crop farming, and small-scale agriculture, suggesting that productivity gains can be achieved without further deforestation. Key barriers to these gains include limited access to credit, underdeveloped land rental markets, poor infrastructure, and gaps in technological diffusion. On the protection side, the report highlights the need to combat small-scale Amazon deforestation, enforce the Forest Code on private lands via the Rural Environmental Registry (CAR), and develop market-based incentives for biomes like the Cerrado.

The report argues that Brazil can simultaneously grow agricultural production and protect natural resources by improving land-use efficiency. It identifies key barriers to environmental protection, such as small-scale deforestation in the Amazon and lack of monitoring in other biomes like the Cerrado. For agricultural production, it highlights that non-geographical factors—including limited access to credit for small-scale farmers, underdeveloped land rental markets, and poor infrastructure—hinder productivity. The document recommends an integrated P&P strategy involving systematic monitoring and a public-private consortium to implement targeted policy interventions.

The IFC-PPCR project in Nepal aims to build climate resilience in the agricultural sector by incentivizing private actors to train farmers in improved agronomic practices and expanding access to climate-adaptive finance. The project targets 15,000 farmers growing rice, maize, and sugarcane in the Terai region. Key strategies include using PPCR grants to cover start-up training costs for agribusinesses and developing a risk-sharing facility to encourage local commercial banks to lend to the high-risk agricultural sector. While agribusinesses see a business case through improved crop supply and quality, banks are motivated by market potential and regulatory mandates to increase agricultural lending. The project highlights the importance of early consultation and tailored capacity building to overcome public and private sector reluctance in Least Developed Countries.

The Kalimantan Forests and Climate Partnership (KFCP) was a publically funded demonstration project (2009–2013) aimed at rehabilitating degraded peat swamp forests in Central Kalimantan, Indonesia. While it did not fully achieve its objective of demonstrating effective rehabilitation at scale, it provided critical technical data, an innovative canal-blocking design, and a model for community engagement through 'Village Agreements'. The study estimates that if such projects can save 26 million tons of carbon over 30 years, they could be financially viable for private investors at carbon prices between AUD 4 and AUD 23 per ton. However, significant barriers remain, including contradictory land-zoning laws, uncertain revenue-sharing frameworks, and the need for robust national measurement, reporting, and verification (MRV) systems.

The executive summary of 'The Global Landscape of Climate Finance 2013' reports that global climate finance flows have plateaued at USD 359 billion, a figure significantly lower than estimated investment needs. The document emphasizes that public policies and resources act as the 'engine room' of the system, necessary to reduce risks and costs to attract private capital, which is essential for scaling low-carbon and climate-resilient growth.
