The first Mobile Energy Efficiency Optimization project with Telefonica Germany and Nokia Siemens Networks’ Energy Solutions has been completed, and it looks like the German carrier stands to do well by doing good.
Telefonica Germany participated in the GSMA’s Mobile Energy Efficiency (MEE) Benchmarking service that helps wireless carriers lower their energy costs and carbon footprint by benchmarking network energy efficiency; during the past three years, the carrier says it improved network energy efficiency by 14 percent per connection. As a result, Telefonica Germany signed up to the GSMA’s MEE Optimization service, which identified an additional cost-saving potential of $2.4 million per year.
Launched last year, the MEE Optimization is a follow-on service from MEE Benchmarking that develops action plans that help wireless carriers reduce network energy costs and greenhouse gas emissions. It identifies energy-saving measures and assesses the business case of each measure, enabling operators to implement cost-effective solutions. Telefonica Germany investigated 20 cell sites in country to gather detailed data on their performance. Smart meters also were deployed to improve the accuracy of the data.
Notes from the Telefonica Germany project:
>> Application of Smart Energy Control Solution: Annual savings of $524,000 (nine-month payback), 2 gigawatt hours of electricity (GWh) and 1 kilotonne of carbon dioxide emissions (KTCO2) are estimated by Nokia Siemens Networks.
>> Switching to more efficient rectifiers: The aim is to help ensure that rectifiers used on site are high efficiency and the upgrade provides optimal results. This results in estimated annual savings of approximately $1.3 million in operating expenses, and as much as 5 GWh and 2 KTCO2.
Notes Gabriel Solomon, Public Policy head at the 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."
