Vodafone Türkiye partners with YEO Technology on a $100 million investment to build solar power plants that will meet 35% of its annual energy consumption—marking the largest ESCO model energy project in Turkey.
Vodafone Türkiye to Be Powered by the Sun: A Landmark ESCO Partnership
CALL Energy is set to lead a large-scale initiative that will contribute significantly to Vodafone Türkiye’s sustainability goals. The project will deliver clean, solar-based electricity equivalent to 35% of Vodafone Türkiye’s current annual energy consumption, reinforcing both companies’ commitment to sustainable development.
1.5 Million Square Meters of Solar Infrastructure Across Turkey
The project scope includes the development of solar power plants across approximately 1.5 million square meters of land in Central , Southeastern, and Eastern Anatolia regions of Türkiye. These plants will be fully designed, financed, and operated by CALL Energy under the ESCO model and will be transferred to Vodafone Türkiye at the end of the contract duration.
Exclusive Green Energy Supply for 15 Years
All electricity generated by these solar power facilities will be balanced with Vodafone Türkiye’s energy consumption, providing the telecom giant with long-term energy cost stability for a duration of 15 years and continue to operate the power plants until the end of the service life. These projects will also contribute to the country’s clean energy goals.
