Stalled by Streams: The Güzelyurt Geothermal Project and Turkey’s Environmental Balancing Act
Date: June 8, 2026
Introduction: A Promising Project Hits a Geological Snag
In a development that underscores the growing complexity of renewable energy infrastructure in Turkey, the proposed Güzelyurt Jeotermal Enerji Santrali (JES) in Aksaray province has been halted—not by market forces or technical failure, but by the very landscape it sought to inhabit. The 20 MW geothermal power plant, a flagship investment by GMK Enerji subsidiary Güzelyurt Jeotermal Enerji A.Ş., has been forced into a major revision after environmental and hydrological assessments revealed that the original site was dangerously crisscrossed by numerous dry stream beds.
What initially appeared as a routine environmental review has now evolved into a significant case study for the Turkish energy sector. It highlights a critical tension: while Turkey pushes aggressively for domestic, baseload renewable energy from geothermal sources, it cannot ignore the physical realities of its geography—especially in regions prone to sudden flash floods and seismic activity. The decision by the Aksaray Governorship and the State Hydraulic Works (DSI) to demand the termination of the original Environmental Impact Assessment (EIA) process signals a new era of rigorous pre-construction scrutiny. This article delves into the details of the Güzelyurt JES project, the reasons for its stalling, the planned revisions, and what this means for the future of geothermal energy in Turkey.
Project Overview: The Ambition of Güzelyurt JES
The Güzelyurt JES was conceived as a mid-sized but strategically important geothermal installation. Planned for a region straddling the Gülyurt and GülAğaç districts—specifically within the boundaries of Güzelyurt, Bozcayurt, Akyamaç, and GülAğaç villages—the project was built on a 2023/15 operating license area. The initial plan was robust: two separate units, each with a thermal capacity of 10 MWt and an electrical capacity of 10 MWe, culminating in a total installed electrical power of 20 MW.
With an estimated investment value of 490 million Turkish Liras (approximately USD 15-20 million, depending on exchange rates), the project was not trivial. It promised a tangible contribution to Turkey’s renewable energy targets. The projected annual electricity generation was calculated at 160,000,000 kWh. To put this into a relatable context, the company noted that this amount of energy would be sufficient to meet the annual electricity needs of approximately 47,620 people—roughly the population of a small Turkish city or a large town.
Geothermal energy holds a special place in Turkey’s energy mix. Unlike solar and wind, which are intermittent, geothermal provides stable, 24/7 baseload power with a very low carbon footprint. Turkey is already one of the world’s leading countries in geothermal energy capacity, second only to China and the United States in terms of installed capacity. Most of this development has historically been concentrated in Western Anatolia (e.g., Denizli, Manisa, Aydın). The Güzelyurt project represented an ambitious push eastward into Aksaray, a province in the Central Anatolia Region known more for its volcanic Cappadocian landscape than its geothermal potential. This geographic novelty was part of its appeal—and part of its risk.
The Stumbling Block: Hydrology and Disaster Risk
The project’s downfall, as initially configured, was not about geothermal fluid chemistry or seismic risk from drilling. It was about surface water—or rather, the absence of it most of the time. The critical issue identified by the Aksaray Governorship and DSI was that the planned site intersected with numerous "kuru dere," or dry streams.
In the arid and semi-arid climate of Central Anatolia, dry streams are a common feature. They are riverbeds that remain dry for most of the year, only carrying water after heavy rainfall or sudden snowmelt. However, to dismiss them as insignificant would be a grave error. In hydrological science, these dry streams are critical drainage pathways. When intense rainfall events occur—a phenomenon becoming more common due to climate change—these quiet, dusty gullies can transform into raging torrents within minutes.
The official objection from the Aksaray Governorship was stark. The letter reportedly stated that because the project site intersected so many of these dry streams, it could lead to "unwanted events" during a sudden downpour or disaster situation. This is coded language for flash floods, soil erosion, and potential structural failure. Imagine a geothermal power plant with its sensitive turbines, cooling towers, and electrical substations suddenly being washed over by a meter-high wave of mud and debris. The consequences would be catastrophic: not only loss of equipment and investment but potential loss of life among workers and nearby residents, as well as environmental contamination from spilled fluids (even if geothermal brines are less toxic than other industrial wastes).
The State Hydraulic Works (DSI), Turkey’s authority on water management, independently confirmed the finding. Their technical review concluded that the project area intersected with too many drainage lines. The DSI did not merely offer a suggestion; they formally requested either that "structural measures be taken" (e.g., massive culverts, diversion channels, or raised platforms) OR that the project site be revised entirely. Furthermore, they explicitly demanded the termination of the ongoing EIA process.
This dual demand from both local government and the DSI left Güzelyurt Jeotermal Enerji with no choice. Continuing with the existing site would mean embarking on an expensive, uncertain legal battle and potentially facing future liability for any disaster. The path of least resistance—and most prudent engineering—was to relocate.
The EIA Process: A Mechanism That Worked
It is important to note that the stalling of this project is not a sign of failure but evidence that Turkey’s environmental regulatory framework is functioning. Critics of energy development often argue that EIA processes are mere formalities, rubber-stamped to allow rapid construction. However, the case of Güzelyurt JES suggests otherwise. The system flagged a fatal flaw, and the responsible authorities—Aksaray Valiliği and DSI—had the power and will to stop the process.
The original EIA application would have included a detailed environmental management plan. But the hydrological survey, likely a mandatory component of the EIA, revealed the stream intersections. The authorities determined that the proposed mitigation measures were insufficient, or that the inherent risk was too high. By demanding the termination of that specific EIA (i.e., for the original site), they forced the developer back to the drawing board. This is precisely what the EIA regulation is designed to do: prevent projects from being built in manifestly unsuitable locations.
For GMK Enerji, this is undoubtedly a costly delay. EIA processes take months, sometimes over a year. Having to restart the process with a new site means new baseline studies, new public participation meetings, and new reports. The 490 million TL investment is now on hold until the new site is fully approved. However, in the long run, this decision likely saved the company from a far worse fate: a plant destroyed by a flood, followed by lawsuits, insurance nightmares, and reputational damage.
The Solution: A 1,450-Meter Shift Southward
Faced with the necessity of change, Güzelyurt Jeotermal Enerji revised its plans. The new proposed site for the power plant will be located approximately 1,450 meters (almost 1.5 kilometers) south of the original location. This is not a trivial adjustment; it represents a significant relocation, likely moving the plant from a riskier, stream-dense area to a more geomorphologically stable zone.
The new coordinates still place the project within the broader administrative boundaries of Güzelyurt and GülAğaç districts and the same villages: Güzelyurt, Bozcayurt, Akyamaç, and GülAğaç. This is important for several reasons:
1. Community Relations: The company has already engaged with these villages during the initial EIA phase. Staying within the same general area means they do not have to start from zero with new communities, preserving some social license to operate.
2. Resource Access: The geothermal resource (the hot water reservoir underground) is not a point source but typically extends over a subsurface area. Moving 1.45 km south likely still allows the company to drill production and reinjection wells into the same geothermal reservoir, though new well pads will be needed.
3. Infrastructure: Transmission lines, access roads, and pipeline routes planned for the original site may need to be redesigned, but the shift is not so massive as to render all previous work obsolete.
The key question is whether the new site has been thoroughly vetted for the same hydrological issues. It is reasonable to assume that the revised location was chosen precisely because it does not intersect with major dry stream beds. The developer and authorities will need to confirm this with new topographic surveys, hydrological modeling, and flood risk assessments.
Technical and Logistical Implications of the Relocation
Relocating a geothermal power plant is not like moving a shipping container. It carries profound technical and logistical consequences:
1. Wellfield Redesign: The heart of any JES is the production wells that bring geothermal fluid to the surface and the injection wells that return the cooled fluid to the reservoir. The original well pad locations were presumably optimized for the original plant site. Moving the plant 1.45 km south may require longer pipelines between the wells and the plant, increasing heat loss and pumping costs. Alternatively, new wells may need to be drilled closer to the new site, an expensive proposition.
2. Topography and Civil Works: The new site must be prepared for construction. If it is on a slope rather than flat land, terracing and retaining walls will be necessary. Soil bearing capacity must be re-evaluated. While the original site may have required extensive drainage works, the new site might require different civil engineering challenges.
3. Grid Connection: The original plant site likely had a planned point of connection to the nearest transmission line. Moving the plant by 1.45 km could change that connection point, potentially requiring a longer or rerouted transmission line, which in turn would require its own environmental permits and land acquisition.
4. Permitting Timeline: The termination of the original EIA means the clock has reset. Güzelyurt Jeotermal Enerji must now file a completely new EIA application for the revised site. This involves a new application file, a new EIA report (or a request for an EIA decision), a new public meeting (the "Halkın Katılımı Toplantısı"), and a new review period by the Çevre, Şehircilik ve İklim Değişikliği Bakanlığı (Ministry of Environment, Urbanization and Climate Change). This process typically takes a minimum of 6-12 months, assuming no further objections.
Broader Implications for Turkey’s Geothermal Sector
The Güzelyurt JES story offers several lessons and signals for the Turkish energy market:
1. Site Selection is Paramount: For years, the geothermal rush was focused on resource availability—finding the hottest water closest to the surface. Güzelyurt demonstrates that resource is only one variable. Hydrology, geology, seismic risk, and land use are equally important. Future projects will likely see more rigorous pre-feasibility studies that integrate hydrology from day one.
2. Climate Change is a New Variable: The authorities’ concern about flash floods is not hypothetical. Turkey has experienced devastating floods in recent years, including the Black Sea floods of 2021 and 2023 and Mediterranean coastal floods. A warming atmosphere holds more moisture, leading to more intense rainfall events. Even if a dry stream has been dry for a decade, climate models suggest it could flood catastrophically. Regulators are clearly internalizing this risk.
3. DSI’s Growing Role: The State Hydraulic Works (DSI) is emerging as a powerful gatekeeper for energy projects. Traditionally focused on irrigation, drinking water, and hydroelectric dams, DSI is now asserting its authority over any project that could impact or be impacted by water flows. Energy developers must now treat DSI as a key stakeholder from the very beginning of project design.
4. Cost of Delay: The 490 million TL project will now face increased costs. Inflation in Turkey has been a persistent challenge, and a 12-18 month delay could add 20-30% to construction costs. Additionally, the company may face penalties or contract renegotiations with turbine suppliers and EPC contractors. This could cool investor enthusiasm for greenfield geothermal projects in less-proven regions.
5. Public Safety First: Perhaps the most important implication is the message sent to the entire industry: No project is too big, and no energy source is too green, to be exempt from safety regulations. Geothermal is renewable and low-carbon, but it is not harmless. A flooded power plant could release hydrogen sulfide gas (H2S), hot brine, or cause structural collapse. By demanding the termination of the original EIA, the authorities prioritized public safety over expedited energy production.
Community and Environmental Perspectives
While the news article focuses on the administrative and hydrological details, the perspective of local communities is crucial. The villages of Güzelyurt, Bozcayurt, Akyamaç, and GülAğaç are likely small, agricultural communities. For them, a geothermal plant brings both promise and peril.
On the positive side, a JES of this size would create direct employment during both construction (100-200 workers) and operation (20-30 permanent skilled jobs). It would also generate tax revenue for the local municipality and potentially provide cheap heat for greenhouses (a common synergy with geothermal plants in Turkey). The 47,620 people whose electricity needs would be met are mostly in nearby Aksaray city and surrounding towns.
On the negative side, local residents have often protested geothermal drilling due to noise, truck traffic, and concerns about induced seismicity (minor earthquakes). In the original site, the added fear of flash flooding would have been a major concern. The relocation 1.45 km south might alleviate some of these fears—or it might simply transfer the risk to a new area. Local residents will have the opportunity to voice their concerns during the new EIA process’s public meeting.
Environmental non-governmental organizations (NGOs) in Turkey, such as the Chamber of Environmental Engineers or local nature associations, will likely scrutinize the new EIA application carefully. They will ask: Has the new site been adequately assessed for ecological sensitivity? Does it intersect with any wetlands, forests, or wildlife corridors? The fact that DSI and the governorship forced a revision will be seen as a victory for environmental rule of law.
Comparison with International Practices
Turkey is not alone in facing these challenges. In the United States, the Geysers geothermal field in California—the world’s largest—is located in a seismically and hydrologically complex region. Projects there have faced decades of permitting battles over water usage and stream diversion. In Iceland, geothermal plants are built only after exhaustive hydrological and glaciological studies to prevent jökulhlaups (glacial outburst floods). In New Zealand, the resource consent process for geothermal projects explicitly requires flood risk assessments.
Turkey’s approach in the Güzelyurt case aligns with these international best practices. The authorities recognized that energy infrastructure should not be placed in harm’s way. The decision to request a site change rather than merely demanding expensive mitigation measures shows a precautionary principle that is still unfortunately rare in fast-moving energy markets.
What Happens Next?
As of June 8, 2026, the situation is as follows: The original EIA process has been terminated. Güzelyurt Jeotermal Enerji A.Ş. is preparing a new project file for the site 1,450 meters to the south.
The company must now:
1. Conduct a new environmental baseline study for the revised site, including a detailed topographic and hydrological survey.
2. Prepare a new EIA application report.
3. Submit the report to the Ministry of Environment, Urbanization and Climate Change for review.
4. If the ministry determines an EIA is required (as is likely for a 20 MW plant), a public meeting will be held in the affected villages.
5. The ministry will then issue a final "EIA Positive" or "EIA Negative" decision. Given that the new site was chosen to address the previous objections, an EIA Positive is likely, but not guaranteed.
6. Upon approval, construction can begin—likely in late 2027 or early 2028, pushing the planned operational date to 2029 or later.
Conclusion: A Necessary Detour on the Road to Renewable Energy
The Güzelyurt JES project’s stalling is, at first glance, a setback. A 20 MW geothermal plant that could power 48,000 people has been delayed by dry streams. But a deeper reading suggests a more optimistic narrative: Turkey’s regulatory system is maturing. The Aksaray Governorship and the State Hydraulic Works demonstrated that they will not sacrifice public safety for megawatts. The developer, while facing delays and increased costs, has the opportunity to build a safer, more resilient plant.
For the Turkish energy sector, the lesson is clear. The era of rapid, unconstrained renewable energy build-out is giving way to an era of smarter, more sustainable development. Geothermal energy remains a vital part of Turkey’s low-carbon future, but it must be pursued with eyes wide open to the landscape. The dry streams of Aksaray have spoken, and their message is one of caution and resilience. The Güzelyurt JES will likely still be built, but it will be built in the right place—1,450 meters south, where safety and sustainability can finally align.
As the world watches Turkey’s energy transition, this case will serve as a reference point. It proves that even "green" energy projects must earn their place on the land, and that environmental assessments are not mere formalities but essential tools for preventing disaster. The Güzelyurt project is delayed, but in the long arc of sustainable energy development, that delay may be the very thing that ensures its success.
