A power transformer failure at the Kolatoli bypass substation on May 28, 2026, caused eight days of extensive load-shedding in Cox's Bazar. This crisis, coinciding with the Eid-ul-Adha holiday, severely disrupted hotel services and caused approximately 30,000 tourists to cancel bookings or leave the city. Electricity was restored on June 5, 2026, after the installation of a new 16/20 MVA transformer.
