The Challenge of Institutional Investment in Renewable Energy

This executive summary by the Climate Policy Initiative (CPI) examines the potential for institutional investors—such as pension funds and insurance companies—to fund renewable energy infrastructure. It identifies three primary investment channels and analyzes the policy, regulatory, and institutional barriers that prevent these investors from lowering the cost of capital for renewable energy projects.

• Institutional investors manage $71 trillion in assets, but their ability to lower the cost of renewable energy depends on the investment channel used. Investment in corporations is the easiest path and could cover all corporate equity and debt needs for the next 25 years, but it is unlikely to lower financing costs because corporations make decisions based on their own strategies. Direct investment in projects has the highest potential to lower the cost of capital due to the investors' long-term horizons, but it is the most difficult path; CPI estimates these institutions could provide at most roughly one quarter of project equity and one half of related debt required through 2035. Pooled investment vehicles offer a middle ground but have seen mixed results due to high fees and uncertain cash flow profiles.
• Three types of policy barriers discourage institutional investment in renewable energy: incentives that are incompatible with the investors' tax status (such as U.S. tax credits for tax-exempt pension funds), unrelated policies that create conflicts (such as European energy market policies forcing a choice between generation and transmission assets), and inconsistent policies that create perceived risk (such as retroactive tariff cuts in Spain or the start-stop expiration of incentives in the U.S.).
• Internal institutional practices and financial regulations further limit direct investment. Many funds lack the specialist expertise to invest directly in renewables, and building such capacity is considered difficult for institutions with less than $50 billion under management. Additionally, the need to maintain liquidity, transparency, and diversification to ensure the security of pensions and insurance policies often conflicts with the illiquid nature of direct project investments.
• Pension assets within the OECD are highly concentrated, with 90% of these assets located in only six countries, meaning the potential for renewable energy investment is unevenly distributed globally, although insurance assets are more evenly spread.
