Vip mobile, the youngest of Serbia’s three mobile operators, is running a base station powered by solar and wind energy as part of a trial into renewal energy. The site provides coverage to several kilometers along the Belgrade-Nis highway that has no electricity grid connectivity. The operator is using Nokia Siemens Networks’ Energy Solutions, which can reduce the use of diesel generators at sites by as much as 90%.
“We are committed to extending network connectivity to under-served areas of the country, while ensuring the environmental impact of our overall operations remains limited. Renewable energy addresses these requirements by minimizing our reliance on diesel generators to power telecom infrastructure in areas with limited or no grid connectivity,” said Rene Schiefer, head of Access Network at Vip mobile. “Nokia Siemens Networks brings strong understanding of telecom network power requirements and management to provide a solution that helps us lower carbon dioxide emissions.”
The Off-Grid Site Solution provided by Nokia Siemens Networks uses solar panels, wind turbines, deep cycling batteries, alongside diesel generators for backup, and a “Green Energy Controller” that manages these components. The solution typically reduces the diesel generator runtime from 24 hours to an average of less than 3 hours per day.
As part of the six-month trial, Nokia Siemens Networks has enabled remote energy management of the site through its NetAct network management platform. This enables Vip mobile to monitor all green energy components anytime and eliminates the need for physical visits to install and maintain new software. The solution increases site reliability by ensuring round-the-clock power availability, providing return on investment in less than three years.
“Nokia Siemens Networks is committed to helping telecom operators reduce the cost of running their networks and strengthen their credentials as environmentally responsible organizations. With more than 80 percent of an operator’s total energy consumption taking place in the network, there is a large scope for them to minimize both their energy costs and carbon footprint by tapping renewable energy. Our Energy Solutions optimize this potential and provide a cost-effective transition to more energy-efficient networks,” said Josef Fuhl, head of the customer business team for Austria at Nokia Siemens Networks.
