Renewable energy auctions have become the dominant mechanism for procuring new wind and solar capacity worldwide. However, recent supply chain disruptions—exacerbated by the COVID-19 pandemic and geopolitical tensions—have exposed vulnerabilities in auction designs that can delay projects and increase costs.
According to the International Energy Agency (IEA), auction volumes for renewable energy reached record levels in 2023, but many projects faced delays due to shortages of key components like solar panels, wind turbines, and critical minerals. The IEA has highlighted that supply chain bottlenecks could threaten the pace of renewable energy deployment needed to meet climate goals.
To enhance resilience, policymakers are considering several measures. These include indexation of auction prices to raw material costs, flexible timelines for project completion, and diversification of supply sources. The International Renewable Energy Agency (IRENA) recommends incorporating supply chain risk assessments into auction design and promoting local manufacturing to reduce dependence on a few suppliers.
Industry experts also suggest that auctions should include penalties and incentives that account for force majeure events, allowing developers to recover from unforeseen disruptions without losing their contracts. Such reforms aim to balance the need for competitive pricing with the reliability of project delivery.
As the world accelerates the energy transition, making auctions resilient to supply chain shocks will be crucial to ensure that renewable energy targets are met on time and at an affordable cost.
