A1 Telekom Austria AG plans to expand its Smart Energy Control (SEC) pilot project nationwide, which is expected to save 1.2 GWh of electricity and prevent at least 432 tones of CO2 emissions in 2010. This translates into annual savings of about 175,000 Euros (about $223,000).
The pilot project, aimed at reducing power consumption at its mobile network, is part of the company’s “A1 energy management program” in which energy efficiency is aimed for through the intelligent use of GSM resources. The company called on Nokia Siemens Networks to help implement its intelligent energy management system in its mobile networks, which uses Nokia’s Event Analyzer (EvA) at the core of its SEC pilot project.
Mobile carriers like Nokia, Ericsson and Vodaphone have been looking for ways to improve energy efficiency for several years to reduce their energy consumption and cut their CO2 emissions.
The Nokia EvA automation solution delivers four functions to solve network challenges including automatic power down of cells to save energy, auto reset to repair network faults for lower downtime, auto change of network parameters to reduce the impact of faults on the network, and automated processes to increase fault detection, escalation or repair.
The initial project, implemented in Vienna at 303 locations with both 900 MHz and 1800 MHz resources, showed the greatest energy-saving potential at night and at weekends. In addition, the intelligent algorithms used by the SEC differentiated between short-, medium- and long-term energy-saving models, which allowed for automatic activation and deactivation of finely-tuned hotspots such as those encountered at events, spontaneous happenings or city tourism, said Nokia.
As a result of the pilot project’s success, A1 Telekom Austria is now planning to incorporate “intelligent energy savings” into its high-capacity UTMS network.
The telecommunication services provider has implemented a number of sustainability projects over the years that range from providing company bicycles for employees to equipping transmission stations with energy-efficient air-conditioner units and using wind turbines.
