GSMA Finalizes Mobile Energy Efficiency Optimisation Project with Telefonica Germany

Apr 10, 2012 (Close-Up Media via COMTEX) -- The GSMA has announced the successful completion of the first Mobile Energy Efficiency Optimisation project with Telefonica Germany and Nokia Siemens Networks' Energy Solutions.

In a release, the Company said that Telefonica Germany participated in its Mobile Energy Efficiency Benchmarking service, which helps mobile operators lower their energy costs and carbon footprint by benchmarking network energy efficiency, and over the past three years has improved network energy efficiency by 14 per cent per connection.

Keen to improve its energy efficiency further, Telefonica Germany signed up to the GSMA's MEE Optimisation service, which identified an additional cost saving potential of euro 1.8 million per year.

"We are delighted that this collaboration with Telefonica and Nokia Siemens Networks is a success and look forward to achieving the identified savings," said Gabriel Solomon, Head of Public Policy, GSMA. "The GSMA is focused on replicating this success with other networks around the world as we increasingly see that energy efficiency is a strategic priority for mobile network operators globally." "At Telefonica we are fully committed to improving our energy efficiency and have defined public improvement targets and dedicated efforts for over a decade to this area, as part of Telefonica Group's energy and carbon strategy," said Gabriel Bonilha, Head of Energy Efficiency, Telefonica Group. "Being a MEE pioneer has helped us to quantify the opportunity ahead of us and this optimisation exercise, supported by the GSMA and Nokia Siemens Networks, is an important step in seizing that opportunity." "Working with the GSMA and Telefonica helped Nokia Siemens Networks to understand and provide innovations and high quality solutions to enhance energy efficiency in Telefonica's Mobile Broadband business," said Nestor Gonzalez, Head of Sales, Global Services, Nokia Siemens Networks. "Increasingly we see an ever greater convergence between good energy efficient performance and eco-sensitive design which helps to reduce the carbon footprint of telecommunications equipment." Energy efficiency measures that Telefonica Germany identified: -Application of Smart Energy Control Solution: Annual savings of euro 400 000 (nine-month payback), 2 gigawatt hours of electricity and 1 kilotonne of carbon dioxide emissions are estimated by Nokia Siemens Networks; and -Switching to more efficient rectifiers: The aim is to ensure that rectifiers used on-site are high efficiency and the upgrade provides optimal results. This results in estimated annual savings of approximately euro 1 million in operating expenses, and up to 5 GWh and 2 KTCO2.

The project identified overall estimated annual savings of up to euro 1.8 million in Telefonica Germany's radio network, by undertaking the measures outlined above, with financial paybacks of nine to 30 months. The energy and carbon savings identified totalled up to 9 GWh and 4 KTCO2 respectively. These savings would be in addition to the measures that Telefonica is currently implementing, which include switching more cell sites to free cooling.

The project for Telefonica investigated 20 representative cell sites in Germany, gathering data on performance. Smart meters were also deployed to improve the accuracy of the data. The information was assessed and a summary of results produced.

The GSMA represents the interests of mobile operators.
