Comprehensive information about the COP29 Global Energy Storage and Grids Pledge: 58 countries committed to 1,500 GW of energy storage capacity and 25 million km of grid infrastructure by 2030, building on the COP28 commitment to triple renewable energy capacity to 11,000 GW.
Information sourced from official COP29 documentation
The Global Energy Storage and Grids Pledge, launched at COP29, builds on the COP28 commitment to triple global installed renewable power capacity to at least 11,000 GW by 2030. This pledge integrates the crucial role of energy storage and grid expansion as the cornerstone of a resilient, decarbonized energy system.
Global energy storage capacity reached approximately 230 GW in 2022. According to Bloomberg NEF estimates, this capacity is forecasted to reach 650 GW by the end of this decade. However, current installed capacity and projected trends are not sufficient to ensure a green energy transition.
To fill this gap and enable achievement of the COP28 outcome on tripling renewable energy capacity, the G7 committed to a global energy storage target of 1,500 GW by 2030—a six-fold increase from 2022 levels. Furthermore, annual global investment in grid infrastructure needs to reach USD 600 billion by 2030 according to IEA analysis.
Energy storage and grid infrastructure are inherently interdependent, with storage technologies enhancing the ability of grids to integrate intermittent renewable energy, stabilize supply and ensure energy security, while grid expansions and modernizations are necessary to maximize the deployment and efficiency of energy storage technologies.

The Global Energy Storage and Grids Pledge represents a vital global initiative that strengthens renewable energy systems, enhances climate resilience, and demonstrates leadership in the fight for a clean, secure and just energy future.
The pledge directly supports the global goal of tripling renewable energy capacity by 2030 agreed at COP28. By focusing on actionable targets like grid investments and energy storage, it ensures tangible progress with focus on the enablers of getting to 11,000 renewable gigawatts.
With 58 countries across all continents and numerous private and non-governmental organisations already committed, this pledge represents a broad, united front to address the critical challenges of renewable energy integration.
The pledge includes well-defined targets essential to achieving a net-zero future: deploying 1,500 GW of energy storage by 2030, doubling global investments in grid infrastructure, and developing 25 million kilometers of grid infrastructure to ensure renewable energy reaches every corner of the world.
With support from governments, NGOs, and private-sector leaders including Iberdrola, Hitachi Energy, and Ørsted, the pledge fosters unprecedented collaboration, ensuring diverse expertise and resources are pooled for maximum impact.
Expanding grid infrastructure and energy storage capacity not only accelerates decarbonisation but also enhances energy reliability, supports economic development, and improves energy access in underserved regions.
Organisations and governments endorse the pledge to signal their alignment with its goals and their commitment to contributing within their capabilities to its achievement. Supporting the pledge does not impose any legal obligations on stakeholders. This flexibility ensures broader participation without risking overcommitment.
Energy storage and grid infrastructure determine how much renewable energy can actually be used. Without sufficient storage and transmission capacity, countries face limitations such as curtailment, instability, and congestion.
Storage helps smooth intermittent generation, while upgraded grids ensure energy can travel where it is needed. This combination is essential for achieving the three main objectives of modern clean energy systems:
The pledge promotes a broad range of storage technologies to enhance technological diversity and supply chain resilience
Including sustainable and cost-competitive alternative battery chemistries and materials with focus on second-life and recycling
Large-scale water-based storage systems leveraging elevation differences for energy storage
Including gravity energy storage and other mechanical systems for grid-scale applications
Including hydrogen for long-term energy storage and seasonal balancing
Heat and cold storage technologies for both industrial and grid applications
Addressing needs of local communities especially in remote and island areas
58 countries across all continents have committed to the Global Energy Storage and Grids Pledge, representing a broad, united front to address the critical challenges of renewable energy integration. Participation includes countries from Europe, Asia, Africa, North America, and South America that consider grid expansion and storage deployment essential for economic stability and climate resilience.
The pledge fosters unprecedented cross-sectoral collaboration between governments, NGOs, and private sector companies. Leading energy companies including Iberdrola, Hitachi Energy, and Ørsted have joined numerous other institutions, research organisations, and private sector partners engaging with these goals through policy commitments, investment plans, and technology development.
Note: Supporting the pledge does not impose any legal obligations on stakeholders. This flexibility ensures broader participation without risking overcommitment, allowing organizations and governments to contribute within their capabilities.
