Global investment in power grids reached US$359 billion in 2024, marking a significant 14% increase over the average spending recorded in 2022 and 2023. This surge in investment highlights a growing focus on modernizing and expanding energy infrastructure to support the transition to cleaner and more sustainable energy sources. Key drivers include the integration of renewable energy, advancements in grid technology, and increasing electricity demand driven by electrification trends in sectors such as transportation and industry.
Key takeaways
- Global grid spending hit a record $359 billion in 2024, but remains nearly twice below the investment needed to meet the 1.5°C pathway.
- Advanced economies dominate grid modernization, while most developing nations fall further behind due to structural financing barriers.
- Without urgent de-risking measures to unlock private capital, inadequate grid capacity will slow renewable deployment and jeopardize decarbonization goals.
This record outlay was largely directed at upgrading transmission and distribution infrastructure to support the integration of rapid renewable energy additions, electric vehicles (EVs), and heat pumps, according to a new analysis from the International Renewable Energy Agency (IRENA).
However, the report warns that this investment, while substantial, remains critically insufficient. The $359 billion figure is 1.9 times short of the US$671 billion annual investment level required between 2025 and 2030 to align the world’s energy infrastructure with IRENA’s 1.5°C Scenario targets.
The Concentrated Investment Landscape
The global investment landscape for the energy transition is becoming increasingly uneven, with funding heavily concentrated in a handful of regions. Advanced economies are leading the push: China, the European Union, the United States, Japan, South Korea, and Australia account for the bulk of planned spending on grid modernization.
Their stable regulatory frameworks and mature capital markets allow them to undertake the large-scale, long-term infrastructure upgrades required for a decarbonized future.
Meanwhile, only a few developing markets, most notably Brazil, India, and Indonesia, are gaining real momentum. Their progress is often powered by public financing and rapidly expanding domestic energy demand, but these nations remain the exception rather than the norm in a broader landscape marked by widening disparities in grid readiness.
The Development Finance Bottleneck
For many developing nations, financing the grid upgrades essential to meeting renewable energy targets has become a major systemic bottleneck. According to IRENA, several deep structural challenges prevent these countries from closing the multi-billion-dollar investment gap.
Governments and utilities often have limited fiscal capacity, burdened by scarce financial resources and high levels of public debt that restrict their ability to undertake large, capital-intensive projects.
Cost-recovery constraints further weaken the sector: regulatory and political limitations frequently prevent utilities from charging tariffs that reflect the true cost of service, discouraging private investment and leaving utilities in precarious financial condition.
At the same time, these countries face a dual demand pressure, having to modernize aging, low-quality infrastructure while also expanding capacity to meet rapidly rising electricity consumption, all as they attempt to integrate increasingly variable renewable energy sources
Outlook: The Need for De-Risking Capital
The failure to invest adequately in power grids risks undermining the entire global energy transition. Without timely grid expansion, the unprecedented amount of renewable power currently being built, such as record solar capacity, cannot be effectively transmitted or utilized, leading to energy curtailment and slower decarbonization.
IRENA Director-General Francesco la Camera has consistently called for smarter use of public funds through risk-mitigation tools to unlock the necessary private capital. Urgent action is needed from policymakers to streamline permitting, ensure regulatory clarity, and create mechanisms for recovering grid costs to mobilize the private financing required to reach the necessary annual investment of $671 billion by 2030.
