Energy storage has become an area of focus in many jurisdictions across the globe due to its potential to offer a wide range of benefits to electricity systems. This Expert Guide brings together analysis from our legal experts across 22 jurisdictions.
NPUC has put together this list of electric grid storage battery capacity by country to help visualize the road to renewable energy.
Different countries have developed varied regulatory frameworks to support energy storage, reflecting their unique market structures, policy priorities, and energy transition goals.
Over 65 countries and 100 organisations support the Global Energy Storage and Grids Pledge, led by the COP29 Presidency. The pledge sets out the targets to achieve 1,500 GW in energy storage and 25 million kilometers of grid
Over 65 countries and 100 organisations support the Global Energy Storage and Grids Pledge, led by the COP29 Presidency. The pledge sets out the targets to achieve 1,500 GW in energy storage and 25 million kilometers of grid infrastructure by 2030.
This treemap, created in partnership with the National Public Utilities Council, visualizes which countries had the most grid-scale battery energy storage systems (BESS) in 2023.
According to Rho Motion''s BESS database as of February 2025, by 2027 the top 20 countries'' deployed BESS grid capacity will have grown by at least 289% compared to 2024.

The Energy Storage Program is a global partnership convened by the World Bank Group through ESMAP to foster international cooperation to develop sustainable energy storage solutions for developing countries.
Different countries have developed varied regulatory frameworks to support energy storage, reflecting their unique market structures, policy priorities, and energy transition goals.
Without adequate storage, countries can find themselves stuck if supplies are limited or run out. We''ve investigated the gas and electricity storage capacities of countries around the world, to see who can hold the most.
This treemap, created in partnership with the National Public Utilities Council, visualizes which countries had the most grid-scale battery energy storage systems (BESS) in 2023.
Global energy storage capacity outlook 2024, by country or state Leading countries or states ranked by energy storage capacity target worldwide in 2024 (in gigawatts)
Without adequate storage, countries can find themselves stuck if supplies are limited or run out. We''ve investigated the gas and electricity storage capacities of countries around the world, to see who can hold the most.
Ireland and Germany’s capacities only grew by 28% from the previous year. Meanwhile, South Korea’s capacity remained the same. The International Energy Agency estimates that 1,300 GW of battery storage will be needed by 2030 to support the renewable energy capacity required to meet the 1.5°C global warming target.
This treemap, created in partnership with the National Public Utilities Council, visualizes which countries had the most grid-scale battery energy storage systems (BESS) in 2023. China has nearly half the world’s grid storage battery capacity and keeps growing at a breakneck pace.
To support the global transition to clean electricity, funding for development of energy storage projects is required. Pumped hydro, batteries, hydrogen, and thermal storage are a few of the technologies currently in the spotlight.
According to the International Energy Agency, 1,300 GW of battery storage will be needed by 2030 to support the renewable energy capacity required to meet the 1.5°C global warming target. But how close is the world to reaching that target?
California’s 8.6 GW is the largest capacity of any state and more than twice that of second-place Texas. Although Canada had only 0.4 GW of storage capacity in 2023, it quadrupled its capacity from the previous year. However, its 426% annual growth rate is still not the highest of the top 10 countries.
Our review demonstrates that no jurisdiction currently provides a comprehensive regulatory framework for energy storage, with the majority of jurisdictions currently allowing storage to be defined as “generation” for the purposes of licensing and other regulatory requirements.
