The company „Cyrus Energy“ was founded in February 2002, in Belgrade, in response to the initiative of partners from abroad (the Great Britain) with a view to unifying shared interests and actions in the territory of Serbia and Montenegro in terms of the provision of design, installation, consulting and engineering services, with the application of new technologies and solutions in infrastructure systems for energy distribution. Since November 2015, we are distributor of natural gas, at the „Padina“ urban neighbourhood, which covers two Belgrade municipalities (Vozdovac and Zvezdara). We manage, maintain and develop our own distribution network of total length of 39 km, with over 1,850 natural gas consumers connected to it. Annual sales of natural gas stand at up to 2,300,000 m³. The distribution gas network for the residential area „Mitrovo brdo – Padina“, with operating pressure up to 4 bar, was built entirely using high-density polyethylene pipes (HDPE), dimensions from Ø 180 mm to Ø 32 mm, household gas connections with a dimension of Ø 20 mm, as well as other connections to the distribution gas network with dimension from Ø 20 mm to Ø 90 mm. Locally manufactured polyethylene pipes were used during construction, whereas electrical fusion fitting is produced by „Fusion Provida“ – United Kingdom. All metering–regulating equipment on our distribution gas system, i.e. household metering and regulating sets, regulating stations (RS) and metering and regulating stations (MRS), is manufactured by „Elster Group GmbH“ – Germany, and is regularly serviced and maintained.
