Placing sustainability at the center of its strategy and focusing on people and technology, Enerjisa Distribution Companies – including Başkent EDAŞ and AYEDAŞ – have introduced a groundbreaking technology to Türkiye in collaboration with one of the global leaders in electric infrastructure safety, Osmose Utilities Services Inc. Through this cooperation, the “Stray Voltage Detection” technology will be implemented in Türkiye for the first time.
This innovative solution enables the early identification of electrical faults in urban infrastructure that may not be visible but pose serious threats to human safety. These faults can now be detected with pinpoint accuracy, enabling rapid intervention by field teams.
Driven by its people-oriented approach and a commitment to pioneering technologies in the sector, Enerjisa Distribution Companies have brought this innovation to enhance grid safety and strengthen infrastructure resilience.
Previously tested in Türkiye following its introduction from the Netherlands, the technology is now officially being deployed following a signing ceremony held in Istanbul. The ceremony was attended by Enerjisa Energy CFO Dr. Philipp Ulbrich and Enerjisa Distribution Companies General Manager Oğuzhan Özsürekci, alongside senior Osmose representatives: Adi Srinivasan (Vice President of Underground Systems), Remco Zinkweg (Managing Director of Osmose BV, Netherlands), and Mark Schoenberger (Senior Director of Underground Operations).
According to the agreement signed between Enerjisa Distribution Companies and Osmose, this mobile stray voltage detection technology will be used for six months across Istanbul’s Asian side to make the electricity infrastructure safer. The technology enables the identification of potential voltage leaks in the grid with high precision, and any issues detected will be addressed rapidly and effectively by field teams.
A First for Türkiye: Enhanced Safety in Energy
Developed by U.S.-based Osmose, this advanced system features specialized sensors and camera systems mounted on the rear of pickup vehicles. While in motion at speeds of up to 40 km/h, the system can detect voltage leaks exceeding 1 volt with high spatial accuracy.
The collected data is transmitted in real time to a tablet computer inside the vehicle, allowing operators to monitor leak locations instantly. The system also includes audio alerts, enabling operators to identify leaks even without looking at the screen. To ensure personal data privacy, all visual recordings from the cameras are automatically deleted when the vehicle is stationary.
Successful Field Trials Completed
Field trials were conducted between February and March 2025 with participation from Osmose experts and Enerjisa field teams. The results were as follows:
Each day, detailed inventory reports were generated for detected voltage leaks, including voltage value, GIS ID, address, asset identification, grounding point, photo documentation, and third harmonic data. These analyses enabled the identification of whether faults originated from neutral or phase-to-ground issues, facilitating targeted and timely interventions in risky areas.
“We Will Continue to Invest in Safe and Sustainable Energy”
Highlighting their continued efforts to strengthen Türkiye’s energy infrastructure with a focus on technology and people, Oğuzhan Özsürekci, General Manager of Enerjisa Distribution Companies, stated:
“At Enerjisa Distribution Companies, safety has always been our top priority as we work to ensure uninterrupted power to more than 22 million people across 14 provinces. We operate with a people-centric mindset and aim to maximize the safety of our distribution networks.
This mobile stray voltage detection technology, which we previously tested in the field, will first be implemented in the AYEDAŞ and Başkent EDAŞ regions, and we plan to extend it to all of our operational territories. While enhancing the safety of our services, we will continue to adopt innovative technologies in line with our vision of a better future, to deliver uninterrupted, high-quality, safe, and sustainable energy.”
Also speaking on the cooperation, Dr. Philipp Ulbrich, CFO of Enerjisa Enerji, emphasized the importance of proactive investment in grid safety:
“With the cooperation with Osmose we at Enerjisa Enerji significantly improve the safety of our distribution grids for the benefit of our customers and our employees. Via the innovative solution smaller leakages can be detected easily allowing our maintenance teams to fix them within hours, wherever the damage is located. As safety and security of supply are our top priorities we are investing into this solution already in 2025 and hope that the regulator will consider the spendings starting from next year in the regulated OPEX base in order to provide the right incentives for efficient, scalable solutions like the Omose powerline leakage detection.”
