Is the Fit Right? Considering Technological Maturity in Designing Renewable Energy Policy

This briefing from the World Resources Institute outlines various policy tools for driving investment in renewable energy, matching specific instruments to the commercial maturity of the technology, from early-stage R&D to mature deployment.

• Grants are appropriate for the earliest stages of technology development, specifically research and development (R&D) and early-stage demonstration. R&D grants address the uncertainty of whether a concept will become a viable application, while demonstration grants help technologies that struggle to access commercial investment due to performance uncertainties and a lack of warranties, allowing investors to pilot and evaluate technologies.
• Loan guarantee programs are most effective during the commercialization and early deployment stages. These programs attract private investors by sharing the risk of technical failure with a credible government agency, addressing the uncertainty of project performance that otherwise deters investment.
• Tax credits and feed-in tariffs (FITs) are designed for the commercialization and early deployment stages of innovation. These tools increase the profit earned from electricity production to help offset high upfront investment costs.
• Renewable electricity standards (RES) are most effective for mature technologies in early deployment by creating demand and letting the market determine the most efficient supply. RES can be open to competition or include 'carve-outs' to support specific technologies in the commercialization phase that are not yet cost-competitive.
• A supportive regulatory environment is necessary to prevent renewable energy technologies from facing disadvantages related to utility pricing structures, legal hurdles, and interconnection standards. Neglecting these barriers can increase deployment costs and lower the efficacy of incentive programs.
