What's Happening?
Over 1,500 GW of renewable energy projects globally are currently stalled in grid connection queues, according to Professor Jairo Quirós-Tortós, a sustainable transitions expert at Loughborough University. Speaking at COP31, Quirós-Tortós highlighted
that the future of electrification is heavily dependent on robust grid infrastructure. In Latin America and the Caribbean alone, curtailed clean power resulted in an estimated USD 7 billion loss in 2024. He emphasized that successful energy transitions require a comprehensive system encompassing planning, regulation, finance, permitting, and innovation, all integrated with the communities they serve. The Green Grids Initiative (GGI) has launched a Technical Assistance Solutions Hub to connect governments, regulators, utilities, and system operators with over 30 expert partners, including Loughborough University, to aid in planning, optimizing, and investing in modern grids. This initiative aims to support countries in achieving their ambitious renewable energy targets, such as 35% electrification by 2035 and a tripling of renewables by 2030, which will necessitate adding or replacing over 80 million km of grid by 2040.
Why It's Important?
The significant backlog of renewable energy projects awaiting grid connection poses a substantial challenge to global decarbonization efforts and economic growth, particularly in regions like Latin America and the Caribbean. The estimated USD 7 billion loss in curtailed clean power in 2024 underscores the economic inefficiency and missed opportunities for sustainable development. For the U.S., while the immediate focus of this report is global, the underlying issues of grid modernization and integration of renewables are highly relevant. The U.S. also faces challenges in upgrading its aging grid infrastructure to accommodate increasing renewable energy capacity. Delays in grid expansion and modernization can hinder the deployment of clean energy technologies, impacting job creation in the renewable sector and slowing progress towards climate goals. The GGI's initiative to provide technical assistance could serve as a model or a collaborative opportunity for U.S. efforts to streamline grid development and accelerate the energy transition, ensuring that investments in renewable generation are not undermined by inadequate transmission infrastructure.
What's Next?
The GGI Technical Assistance Solutions Hub will continue to connect countries with expert partners to address grid challenges, focusing on planning, optimization, and investment. Professor Quirós-Tortós will further discuss the role of flexibility in integrating renewable power, including grid optimization, the complementary use of hydropower and battery storage, and how regulation and climate finance can enhance power system security and resilience. The global push towards 35% electrification by 2035 and a tripling of renewables by 2030 will necessitate massive grid expansion and replacement, with over 80 million km of grid infrastructure required by 2040. This ongoing effort will involve continued collaboration between governments, industry, and academic institutions to overcome the systemic barriers currently delaying renewable energy integration. The success of these initiatives will be crucial in determining whether countries can meet their climate targets and realize the full economic benefits of clean energy.
Beyond the Headlines
The issue of grid infrastructure as a 'missing link' in the energy transition highlights a critical systemic challenge that extends beyond technological innovation in renewable energy generation. It points to the complex interplay of policy, finance, and engineering required for a successful energy transformation. The substantial financial losses due to curtailed clean power suggest that the economic models and regulatory frameworks surrounding grid development may be insufficient to keep pace with the rapid growth of renewables. This situation could lead to a re-evaluation of how grid projects are prioritized, funded, and permitted, potentially shifting investment focus from generation to transmission and distribution. Furthermore, the emphasis on linking infrastructure development with the people who will live with them underscores the growing importance of social equity and community engagement in large-scale energy projects, aiming to prevent local opposition from further delaying critical infrastructure.
