Start with the project, not the product
A solar installation, wind farm or energy-efficiency upgrade can have very different funding needs. Development, construction and operation each bring different uncertainties. A useful financing discussion starts with the investment budget, expected revenues or savings, completion timetable and the sponsor’s capacity to absorb setbacks. This overview focuses on electricity and clean-energy investment; it is not a list of currently available lending offers.
1. Equity and strategic investment
Sponsors or external investors contribute capital in exchange for an ownership interest. Equity absorbs business risk and can support early development before debt is available. Investors generally seek returns through distributions and capital appreciation, rather than scheduled loan repayments. Bringing in a partner also means agreeing governance, control and exit arrangements. IEA ↗
2. Corporate lending
A corporate loan is assessed against the borrowing company’s overall financial position and repayment capacity. It can fund an energy investment within an existing business, but the borrower remains responsible for the debt. The project must be considered alongside the company’s other obligations, security arrangements and liquidity needs. IEA — financing landscape ↗
3. Project finance
A dedicated project company can raise debt primarily supported by the project’s cash flows and contractual arrangements. Limited- or non-recourse structures depend on the agreed allocation of risk; sponsor support may still be required, particularly during construction. Detailed due diligence and documentation can make this approach more demanding than a straightforward corporate facility. IEA — financing landscape ↗
4. Green bonds
Green bonds raise debt for eligible environmental projects, including renewable energy. Under ICMA’s voluntary Green Bond Principles, issuers should explain project selection, manage the proceeds and report on their allocation and impact. The green label does not remove repayment obligations or establish that an investment is low risk. Issuance costs and reporting capacity also matter. ICMA ↗
5. Blended finance and development support
Blended concessional finance combines concessional resources with commercial finance to address barriers that otherwise deter investment. It can use instruments such as debt, equity or guarantees. Access depends on the programme and project: it is not an automatic subsidy, and public support does not replace commercial assessment. IFC ↗
Where does a power purchase agreement fit?
A power purchase agreement (PPA) sets terms for selling electricity. It is a revenue contract, rather than a loan or equity investment. Its price structure, duration, buyer credit quality and risk allocation can influence a project’s ability to obtain financing. A signed PPA alone does not guarantee that lenders will fund the project. World Bank ↗
A practical framework for comparison
Compare more than the headline interest rate: consider currency, tenor, repayment profile, fees, security, reserve requirements and reporting obligations. Stress-test lower generation, delayed completion, higher operating costs and weaker prices. For a factory’s solar project, distinguish savings from self-consumption from revenues on electricity sold; do not assume they follow the same contract or pricing model.
Preparing the first discussion
Prepare the project location and technology, development stage, indicative budget, sponsor contribution, permits and grid-connection status, generation assumptions and intended revenue model. Flag unresolved issues openly. In Türkiye and the UK, applicable permissions, market rules and support schemes need project-specific verification. The appropriate structure emerges from this evidence, not from a standard promised debt ratio.
