HEP Opskrba, the leading electricity supplier, has been conducting the '100 Green Trees' campaign as part of the ZelEn project.

Joint by its customers, future and current ZelEn users, HEP Opskrba employees landscape and plant trees around HEP hydropower plants. By doing so, we wish to contribute to the UN's 'A Billion Acts of Green' global campaign for protecting the planet and ensuring sustainable future launched in 2010.

  • In 2017, HEP Opskrba joined the 55th anniversary of Zakučac Hydropower Plant and the Jure Kaštelan Days, an event organized by the town of Omiš, the village of Zakučac and Jure Kaštelan Secondary School from Omiš. Planting 55 poplar trees in the 'Jure's Poplar Trees' line represented a symbolic marking of the Jure Kaštelan Days, on the occasion of which Jure Kaštelan Secondary School pupils performed a recital.
  • In 2016 –Marking the Earth Day, we embarked on landscaping the area around Čakovec Hydropower Plant, the first hydropower plant in Croatia with tubular turbines in the engine room. Čakovec HPP uses the water potential of the Drava river for electricity generation, protects the area from flooding, improves water supply and drainage, and enables the gravity fed irrigation of agricultural surfaces.
  • In 2015 – Marking the International Day of Forests, we embarked on landscaping the area around Kraljevac Hydropower Plant, once the biggest hydropower plant in the Austro-Hungarian Empire, put into operation in 1912. Despite its century long operation, this hydropower plant still runs flawlessly also supplying the entire Makarska Riviera with water.
  • In 2014 – The '100 Green Trees' initiative started in the oldest hydropower plant in continental Croatia – Ozalj Hydropower Plant. It was built back in 1908 and named 'Munjara'. As the neoclassical building in which the hydropower plant is located is deemed a protected cultural monument, many consider it to be one of the most beautiful hydropower plants in the Republic of Croatia.
