A new analysis reveals that Turkey has approved more grid-scale battery storage capacity than any single European Union nation, highlighting a shifting dynamic in the global clean energy transition. The findings suggest that several developing economies are accelerating their adoption of key technologies even as some wealthier nations face implementation challenges.
According to the report, Turkish regulators have greenlit over 33 gigawatts (GW) of battery storage projects since 2022. This approved pipeline significantly exceeds the total planned and operational capacity in European leaders like Germany and Italy, which each stand at approximately 12-13 GW.
The rapid expansion is largely attributed to a 2022 policy mandating preferential grid access for renewable energy projects that are coupled with an equal amount of storage capacity. This rule has triggered a wave of applications, with approved projects already equivalent to 83% of Turkey’s current combined wind and solar capacity. Analysts note that this policy framework has sent a powerful signal to investors, positioning the country to potentially become a regional clean energy hub if the projects are completed.
Battery storage is a critical component for modern electricity grids, especially those integrating high levels of variable renewable sources like wind and solar. By storing excess power when generation is high and discharging it during periods of low wind or sunlight, batteries enhance grid reliability and reduce dependence on fossil fuel-powered backup plants.
Energy experts point to a global trend where plunging costs are enabling this acceleration. The price of solar panels and lithium-ion batteries has fallen by nearly 90% over the past decade, creating what researchers describe as a “tremendous opportunity” for countries to build affordable, clean, and reliable power systems. Turkey, alongside other nations in the global south, is now actively capitalizing on this economic shift.
Despite this progress in storage, Turkey’s overall energy mix remains complex. While it generates about one-fifth of its electricity from wind and solar—a share that leads its immediate region—it continues to rely heavily on coal, which accounted for 34% of power generation last year and benefits from substantial state subsidies. The country has set an ambitious target of reaching 120 GW of installed wind and solar capacity by 2035, but current annual additions are reportedly lagging behind the required pace to meet that goal.
Industry observers caution that realizing the full battery storage pipeline is not guaranteed. Potential obstacles include bureaucratic permitting delays and a market design that relies on volatile spot prices. Furthermore, Turkey’s existing large hydropower capacity provides a form of built-in storage and base-load power, meaning its immediate grid stability needs differ from those of many European countries.
The report emerges as Turkey prepares to host a major international climate summit later this year, focusing global attention on its energy and climate policies. The country’s strides in battery storage underscore a broader narrative: the geography of clean technology leadership is evolving, driven by policy decisions and rapidly improving economics.
