How many GW of battery storage capacity are there in the world?
Strong growth occurred for utility-scale battery projects, behind-the-meter batteries, mini-grids and solar home systems for electricity access, adding a total of 42 GW of battery storage capacity globally.
Battery storage. In 2025, capacity growth from battery storage could set a record as we expect 18.2 GW of utility-scale battery storage to be added to the grid. U.S. battery storage already achieved record growth in 2024 when power providers added 10.3 GW of new battery storage capacity.
How many GW of solar & battery storage will be added in 2024?
Together, solar and battery storage account for 81% of the expected total capacity additions, with solar making up over 50% of the increase. Solar. In 2024, generators added a record 30 GW of utility-scale solar to the U.S. grid, accounting for 61% of capacity additions last year.
What is a small-scale battery energy storage system?
Most U.S. utility-scale battery energy storage systems use lithium-ion batteries. Our data collection defines small-scale batteries as having less than 1 MW of power capacity. Small-scale battery data are reported separately from utility-scale battery systems.

Portugal-based Greenvolt has secured nearly €60 million to build Central Europe's largest battery storage facility, a move that strengthens EU grid resilience and propels Portugal into a leading role in clean energy exports. Why This Matters. Portugal's energy-storage market is entering a new stage of maturity, combining grid-scale standalone batteries and hybrid (co-located) systems with renewable plants. Despite high concentration levels indicated by the HHI, the sector saw a significant growth rate of 27. The market is projected to reach USD 290. The market is driven by substantial government investment programs supporting grid flexibility and renewable. . The growth of solar and wind generation by 2030 could result in 3-5 TWh of curtailment which storage can capture during solar peaks, then discharge to meet evening demand when renewable generation declines. Storage provides real-time flexibility, enabling participation in balancing markets and. .

The pursuit of economic viability by storage facility owners will inherently lead to charging during low-cost hours and discharging during hours that are more economically attractive. Storage can replace thermal generation in constraint markets, easing the grid and supporting Portugal's 2040 phase-out target.
As storage proliferates, the probability of demand curtailment events drops sharply, easing concerns for remote workers who rely on uninterrupted connectivity. If everything on the books is built, Portugal will operate roughly 750 MW of batteries by early 2026, rising toward 2 GW by 2030.
Are battery energy storage systems a good idea for foreigners?
For foreigners used to stable northern-European grids, the proliferation of Battery Energy Storage Systems (BESS) promises familiarity: fewer brownouts, fewer dramatic tariff swings, and a growing menu of smart-home contracts that reward households for charging electric cars when surplus solar floods the lines.
Storage provides real-time flexibility, enabling participation in balancing markets and maintaining grid stability and inertia, especially in Portugal where these markets are growing. Despite the increase in interconnection capacity between Spain and Portugal, it could experience congestions during non-solar hours.
Let's break it down: Lithium-ion batteries: The MVP of storage, averaging €450–€600/kWh [1]. Flow batteries: The new kid on the block, perfect for grid-scale projects (€500–€800/kWh). .
