In the three years since Turkey began fast-tracking battery storage licenses, its energy regulator has approved more than 33 gigawatts of capacity, a volume that matches the combined total greenlit across all 27 European Union member states over the same period. The approvals, documented by the energy think tank Ember using data from Turkey’s Energy Market Regulatory Authority (EPDK), land just months before Ankara hosts the COP31 climate summit later this year, handing the Turkish government a concrete infrastructure achievement to put on the table.
“Turkey has approved more battery storage capacity than the entire European Union combined,” said Euan Graham, an energy analyst at Ember who compiled the licensing data from EPDK’s public portal. “The speed of the regulatory process there is unlike anything we see in European permitting systems.”
The contrast with Europe is stark. EU member states have received roughly 221 GW in battery storage applications since 2022, according to Ember’s calculations drawn from national regulatory filings rather than a single EU-agency dataset. That figure has not been independently verified against consolidated data from bodies such as ENTSO-E or ACER, and readers should treat it as Ember’s own aggregation. Permitting bottlenecks and grid-connection queues have kept actual approvals across the bloc to about 33 GW. Developer interest is not the problem; bureaucratic throughput is. Turkey, working through a single national regulator, has matched that output with a fraction of the administrative complexity.
How Turkey’s approval pipeline works
EPDK processes battery storage projects through a structured pre-license and license system. Developers must post capital guarantees and meet investment cost thresholds before receiving authorization, meaning the 33 GW figure reflects projects that have cleared financial and technical scrutiny rather than speculative filings. Individual board decisions are logged through EPDK’s public licensing portal, though the regulator has not published a single consolidated list of all approved battery projects with their individual capacities, locations, or expected completion dates.
Ember’s methodology relies on extracting and aggregating individual license records from EPDK’s query system rather than drawing on a pre-compiled government total. Assuming most approved projects use one-hour battery configurations, Ember estimates the 33 GW translates to roughly 37 gigawatt-hours of energy storage. That distinction matters: gigawatts measure peak power output, while gigawatt-hours measure how much electricity a grid can actually draw on when solar and wind generation drops. If developers opt for longer-duration systems of two or four hours, the real stored energy could be significantly higher. If projects are downsized during construction, it could fall short.
Battery technologies and developers in the pipeline
EPDK’s licensing records do not specify which battery chemistry each project will use, but industry patterns offer guidance. The vast majority of utility-scale battery storage projects globally rely on lithium-ion technology, particularly lithium iron phosphate (LFP) cells, which have become the default for grid-scale installations because of their cost trajectory and safety profile. Turkey’s approved projects are widely expected to follow that trend, though some developers have explored sodium-ion and flow battery alternatives for longer-duration applications.
Public reporting has not produced a comprehensive list of the companies behind Turkey’s 33 GW of approvals. EPDK’s board decisions name individual licensees, but no aggregated directory of major developers and their respective capacities has been published by the regulator or by Ember. What is visible from Turkish energy trade press is that both domestic firms and international developers have applied for licenses, reflecting broad commercial interest in the market. Until EPDK or an independent tracker publishes project-level data, the composition of the pipeline remains opaque.
Why Turkey is moving fast
Turkey imports the vast majority of its natural gas, a vulnerability that successive governments have tried to offset by expanding domestic renewable generation. Solar and wind capacity have grown rapidly, but without large-scale storage, that generation is difficult to integrate reliably. Battery storage fills the gap, absorbing excess renewable output during peak production and feeding it back during demand spikes or supply dips.
The timing also carries diplomatic weight. Turkey is preparing to host COP31, and officials have been staging the country’s climate credentials in the run-up. A recent preparatory event in Istanbul, attended by the COP31 President-Designate, carried an explicit message about a “new era of climate action,” according to the United Nations office in Turkey. The battery storage numbers give that rhetoric a tangible foundation.
That said, no EPDK official has publicly linked the pace of storage approvals to COP31 hosting. The connection is drawn by international reporting and reinforced by the calendar, but it remains inference. Turkey may be accelerating storage primarily for energy security, with the summit optics serving as a secondary benefit.
The gap between paper and steel
Approved capacity is not installed capacity, and the distance between the two can span years. Construction financing, equipment procurement, supply chain constraints, and grid infrastructure upgrades all sit outside EPDK’s licensing process. No published data quantifies how many of Turkey’s approved battery projects have broken ground, how many are on track to meet their milestones, or how often pre-licenses lapse when developers fail to deliver.
Cancellation and attrition rates remain absent from the public record. EPDK’s pre-license procedures include deadlines and financial penalties that can disqualify developers who fall behind, but without transparent reporting on those outcomes, the 33 GW figure represents regulatory intent rather than confirmed grid capacity.
Europe faces a different version of the same problem. Its 221 GW application backlog, as calculated by Ember, signals enormous market appetite, but until permitting reforms clear the queue, much of that capacity will remain theoretical. Both Turkey and the EU are, in different ways, testing whether policy speed can keep pace with the energy transition’s physical demands.
What COP31 will put to the test
For energy companies and investors watching the summit, Turkey has established something measurable: a permitting environment where large-scale battery storage can advance faster than in most of Europe. Whether that speed translates into a functioning grid asset depends on execution, financing, and whether Turkey’s transmission infrastructure can absorb tens of gigawatts of new storage without costly upgrades.
The summit, expected later in 2026, will likely become the stage where Ankara tests whether regulatory velocity alone is enough to claim climate leadership among G20 economies still wrestling with fossil fuel dependence. The 33 GW number gives Turkey a strong opening argument. What happens on construction sites between now and then will determine whether it holds up.
