Istanbul Electricity, Tramway and Tunnel General Management (İETT) has built its first wind turbine, producing electricity via wind energy in the Beylikdüzü Metrobus parking area. The system works outside the city's electricity network and will produce 17,000 kWh of energy annually for the Beylikdüzü Metrobus operation building. According to data from a meteorology center, the metrobus parking area in Beylikdüzü has been identified as having the highest production capacity for wind energy. The wind turbine will produce 6 kilowatts every day and this will be transferred to the systems supply after being stored in accumulators. The system, which İETT plans to implement at every garage and metrobus platform, will prevent 8,000 kilograms of carbon dioxide gas emissions annually.

İETT has categorized its environmental management activities under "air," "water" and "waste." The institution, which began its environmentally friendly activities with compressed natural gas (CNG) buses, is continuing its new eco-friendly policy with "green garage" projects.

İETT established its first renewable energy facility in Beylikdüzü and aims to increase the number of these facilities in the near future. In 2016, its Energy Headquarters will be established by the institution and İETT will monitor and report on their energy producing facilities.

Celebrating its 144th year, İETT is working on various projects focusing on financial, ecological and energy efficiency in line with its 2023 vision. The system that was installed at the Beylikdüzü Metrobus parking area is expected to set an example to other institutions and projects. The system in Beylikdüzü enables İETT and other institutions to use energy efficiently and decrease the economic burden of energy expenses. The project will help İETT to be more energy efficient and contribute to the fight against global climate change.
