28 Haziran 2026 Planned Power Outage in İstanbul: Details and Expected Process

A comprehensive power outage will occur across İstanbul on Sunday, 28 Haziran 2026, as part of improvement and planned maintenance work on the electrical grid. BEDAŞ, serving on the Avrupa Yakası, and AYEDAŞ, the responsible authority on the Anadolu Yakası, will temporarily halt energy supply in specific districts and neighborhoods across the city. These planned outages are being carried out to further strengthen the city's infrastructure and prevent potential failures. Authorities announced that if the work proceeds as planned, electricity will be gradually restored on the same day. Citizens are expected to take precautions in advance against the outages occurring on this date and arrange their energy needs according to this schedule.

The planned maintenance and repair work may vary regionally during the power outage and will involve a series of technical processes. Carried out simultaneously on both sides, these works aim to renovate existing grid lines, integrate more resilient infrastructure systems, and minimize grid losses. The areas to experience outages have been determined based on the nature of the work and the technical requirements of the site, with implementations planned for different time slots throughout the day. Although the temporary lack of energy supply may partially disrupt daily life, it will make a significant contribution to İstanbul's energy infrastructure in the long run. Experts state that planned outages will prevent sudden and unexpected failures, providing a more resilient system against the increasing energy demand during the summer months.

The gigantic metropolitan structure of İstanbul necessitates extremely meticulous coordination and planning for such infrastructure works. The electricity distribution network, which affects millions of people and thousands of businesses every day, is constantly monitored and periodically renovated in areas where it is needed. Authorities ensure that planned outages generally take place on weekends or during time slots with relatively lower energy demand. In this way, the disruption of commercial activities is minimized, and potential damage to people's social lives is prevented. Thanks to the grid improvement works, İstanbul will take another step toward an uninterrupted and reliable energy infrastructure, in line with the smart city vision of the future.

The list of districts and neighborhoods that will experience outages is shared in detail through the official announcements and platforms of the electricity distribution companies. Since the information regarding when the electricity will be cut off and restored may vary from region to region, it is of great importance for citizens to access up-to-date information from official sources. Companies frequently warn their subscribers to keep their communication systems and mobile app notifications active. Unless there is a technical glitch, electricity will start to be restored automatically and gradually after the planned work hours end. Throughout the entire process, field teams will remain on standby in the areas where the outage is implemented to intervene immediately in case of any issues.

There are several practical measures the public in İstanbul, who will be affected, can take against these planned power outages. In particular, unplugging sensitive electronic devices such as refrigerators and deep freezers is a critical step to protect the devices and prevent sudden voltage fluctuations that may occur when power returns. Additionally, fully charging smartphones, computers, and auxiliary devices like powerbanks before the outage will prevent any communication and connectivity disruptions. In cases where cold-chain sensitive products like medications or special medical devices need to be used, it is essential to have alternative energy sources or cooling systems ready. Finally, avoiding the use of elevators during the outage hours will prevent negative scenarios that could arise due to the lack of backup generator infrastructure in some buildings.
