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 report examines the financing of Nationally Appropriate Mitigation Actions (NAMAs), emphasizing the need to move beyond reliance on international public funding toward leveraging private capital. It defines 'bankability' as the attractiveness of a project to investors based on its revenue-generating potential and provides a framework for designing such projects. Through eight case studies from countries including Morocco, Tunisia, and the Philippines, the document illustrates the roles of public-private partnerships (PPPs), the importance of implementing bodies (such as Special Purpose Vehicles), and the necessity of risk mitigation tools like partial credit guarantees and power purchase agreements. The report concludes with recommendations for NAMA developers to engage the private sector early in the design process and for international stakeholders to disseminate best practices in private funding.

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 details how Illinois municipalities use Community Choice Aggregation (CCA) to pool electricity purchasing power, enabling them to negotiate lower rates and switch to cleaner energy sources. Since 2013, over 90 Illinois towns have transitioned to 100% renewable electricity via Renewable Energy Credits (RECs), increasing demand for wind and solar by over 6 terawatt hours. The document provides case studies from Oak Park and Chicago, analyzes CCA adoption in other states like California and Massachusetts, and offers strategic recommendations for municipalities to move beyond RECs toward local renewable energy investments.

The report examines the transition of U.S. Navy bases in the Southwest toward microgrids to enhance energy security and integrate renewables. It identifies five key findings: the need for more granular design requirements, a conflict between utility-scale renewable goals and microgrid security, the immediate value of enhanced control systems, the complexities of participating in California's electricity markets, and internal Navy bureaucratic barriers. The document recommends that the Navy, grid operators, and regulators collaborate to define reliability needs, quantify the business case, and remove regulatory hurdles to enable microgrid adoption.

Thailand has achieved rapid growth in renewable energy, particularly solar power, through a combination of incentive policies, simplified regulations, and civil society engagement. Key mechanisms include the Small Power Producer (SPP) and Very Small Power Producer (VSPP) programmes, and the 'Adder' feed-in premium. While these policies attracted significant private investment and increased capacity, the government is now transitioning toward a more sophisticated feed-in tariff to manage costs and balance the energy portfolio, as solar growth has significantly outpaced other renewable sources.

The Ouarzazate I CSP project achieved a final bid tariff of USD 0.184/kWh, which was 25% lower than initial projections. This reduction was driven by higher estimated annual power generation (425 GWh versus 370 GWh), lower capital costs through increased local manufacturing content (approximately 65%), and a strategic 'early-mover' approach by the winning consortium, ACWA Power. The project utilizes a public-private partnership model where the public sector assumes most political and financial risks, while the private sector manages construction and performance risks. The study concludes that the model is replicable and scalable, as evidenced by the initiation of a second phase for an additional 300MW of solar thermal energy.

The report identifies significant gaps in risk mitigation for clean investments, particularly regarding policy and financing risks. It categorizes risks into four groups: political/policy/social, technical/physical, market/commercial, and outcome risks. In developed markets, gaps are most acute for policy risk due to retroactive support cuts and for technical risks in immature technologies. In developing markets, while the supply of political risk insurance is higher, policy risk remains under-covered and financing risks are exacerbated by weak domestic financial institutions. The authors argue that an optimal risk allocation framework should assign exogenous risks (like policy) to the public sector and endogenous risks (like technical) to the private sector.

The report examines first-loss protection mechanisms as tools to bridge the financing gap for low-carbon infrastructure by shielding institutional investors from initial losses. It analyzes two primary models: the European Commission-European Investment Bank Project Bond Initiative (EC-EIB PBI) and the proposed Sustainable Development Bond Assurance Corporation (SDBAC). The authors argue that for these instruments to be effective, they must align with investors' risk-return profiles, secure investment-grade ratings from agencies, and be priced competitively, often requiring concessional support from sponsors like development banks to remain viable.

The document examines policy risk—defined as unexpected government regulatory changes—and its impact on renewable energy investments. It analyzes existing tools like MIGA and OPIC political risk insurance and World Bank partial risk guarantees, while detailing a new OPIC FiT insurance product. The report concludes with recommendations for improving these instruments through standardization, expanded geographic scope, and better integration with credit rating agency methodologies to enhance project bankability.

The report examines Viet Nam's investment incentive framework for renewable energy, analyzing financial, fiscal, and market-based supports. While the government has established a policy framework including tax exemptions and price subsidies, stakeholder interviews suggest these incentives have a limited effect on investment decisions due to low electricity off-take prices, regulatory opacity, and a lack of trust in government guarantees. The study highlights a contrast between the modest success of small hydropower and the struggles of wind and biogas projects to achieve financial viability.

The research paper evaluates four types of cost limits—alternative compliance payments, contract price caps, retail rate/revenue impact caps, and renewable energy fund caps—across several U.S. states. It finds that while cost limits can insure against unacceptably high costs, they often create market uncertainty, may act as price floors rather than ceilings, and can conflict with renewable energy targets if not aligned with expected costs. For California, the author recommends avoiding public contract-level benchmarks, ensuring the limit is consistent with expected RPS costs, and implementing a simple, clearly defined mechanism with a predictable review process.

The Walney Offshore Windfarms project, the world's largest installed offshore windfarm at the start of 2012, overcame significant investment barriers through a dual approach. First, the UK government provided a robust policy framework centered on green tradable certificates (ROCs), which provided approximately 60% of expected project revenues. Second, the developer, DONG Energy, employed extensive financial engineering to 'de-risk' the investment for non-utility investors, such as the Dutch pension fund PGGM and Ampère Equity Fund. By using Power Purchase Agreements (PPAs), construction management agreements, and vendor financing, DONG Energy reallocated construction, operation, and price risks away from these institutional investors, effectively transforming their equity stakes into quasi-fixed income positions. The project attracted GBP 1.3 billion in private investment and is projected to avoid 8.3 MtCO2 and 193,000 tons of SO2 over its lifetime.

The report analyzes six case studies—onshore wind in the U.S. and Spain, solar PV in the U.S. and Italy, a solar power tower in the U.S., and offshore wind in Denmark—to determine how policy impacts the cost of finance. It identifies seven policy impact pathways, finding that the duration of revenue support and revenue certainty are the most critical factors in reducing financing costs. The analysis shows that while most projects' costs and returns align with benchmarks, the Italian PV case experienced inflated costs and returns due to a rush to qualify for a Feed-in-Premium. The report concludes that policies reducing risk and providing revenue certainty are essential for attracting institutional investors and scaling innovative technologies.

The document presents a structured 12-step framework for collaborative solar procurement, moving from early regional recruiting and site assessment through to procurement, installation, and long-term operation. The process emphasizes the importance of shared understanding among participants, competitive bidding to ensure best-value vendor selection, and the documentation of energy production and savings over a 25-year horizon.

The report examines the intersection of water scarcity and power generation in South and Southeast Asia, arguing that while regulatory protections have historically shielded shareholders, increasing water stress driven by climate change and demographic pressure creates material financial risks. It introduces a risk exposure framework based on business models, water dependency, and water security, and highlights that a significant portion of existing and planned capacity in the region is located in water-stressed areas.

The document outlines a comprehensive framework for accelerating campus climate initiatives, focusing on five key areas: climate action planning, buildings and utilities, renewable energy, transportation, and carbon offsets. It emphasizes 'whole-system thinking' and 'integrative design' to achieve deep energy savings and carbon reductions more cost-effectively than incremental improvements. The guide addresses common barriers such as insufficient capital, lack of technical expertise, and institutional resistance, offering specific financial tools like Revolving Loan Funds and Energy Performance Contracting. It also provides case studies from various U.S. institutions to illustrate successful implementation of energy-efficient retrofits, renewable energy installations, and sustainable transportation programs.

The document analyzes Egypt's wind energy potential, focusing on the Gulf of Suez, and compares the levelized costs of wind generation against natural gas CCGT. It identifies the primary barrier to expansion as a subsidized natural gas pricing system that makes wind uncompetitive. The report outlines five necessary conditions for large-scale implementation, including a clear long-term strategy, a revised tariff system, and grid reinforcement plans, while discussing the role of the proposed New Electricity Law in attracting private investment.

The 1995 power purchasing agreement between Tanesco and IPTL in Tanzania is cited as a failed public-private partnership due to alleged corruption, lack of feasibility studies, and the procurement of unnecessary diesel-generated power at inflated costs.

The document outlines three primary methods for companies to obtain green power: retail green power programs, renewable energy certificates (RECs), and on-site generation. It provides a business case for the transition, focusing on GHG reduction, stakeholder relations, and cost stability. The guide also details procurement strategies to minimize premiums, such as energy efficiency upgrades and demand aggregation, and explains the methodology for accounting for carbon benefits in corporate GHG inventories using e-GRID emission factors.
