  1. Potential Using of Renewable Energy in Telecommunication Stations Maria de Fátima N.C. Rosolem - CPqD Glauco Ribeiro dos Santos - CPqD Luiz Antonio Soares - CPqD Luiz Eduardo Ferreira Dias Junior - CPqD Pamela Tobias Frare - CPqD Raul Fernando Beck - CPqD Vitor Torquato Arioli - CPqD

  2. Increasing in Telecommunications Demand • Indicatorsof Brasil Telecom (Acces-million) • Mobilephone: 157,5 • Fixed: 41,7 • Broadband: 10,4 • Cable TV: 6,6

  3. Climatic Changes

  4. Renewable Energy • Solar Photovoltaic (PV) • Wind Energy • Storage Systems - Fuel Cell

  5. Solar Photovoltaic (PV)

  6. Solar Photovoltaic (PV) Projeto Data Center - Affordable Internet Services Online Inc.

  7. Clean Energy Silent “Free” and Infinite Modular Well suitable for stand alone applications Low maintenance costs Long lifetime Simple operations High cost Low efficiency Efficiency Degradation Storage systems Operating conditions (poor light conditions) Temperature sensibility Low power density TechnologyPros andCons

  8. Wind

  9. Clean Energy Easy to manufacture Suitable for Large applications Stand alone systems Connected with the grid Competitive Price Huge unexplored potential Noise and visual pollution Competitive Price Low capacity factor Operating conditions (seasons and wind speed dependence) Heavy Infrastructure to install Technology ProsandCons

  10. Fuel Cell

  11. Available Technologies

  12. Stationary application - Telecom • Electrochemical device – DC supplier; • It is a suitable solutions in extreme conditions; • It helps in a low carbon footprint; • It is a interesting solution more, not is the BEST solution. It is better when used combined with other energy sources (batteries, PV and wind)

  13. Run time Environment temperature resistance range (- 25 º to 45 º C) Silent Clean Energy Life time Low Maintenance No recharge time Remote control Start up High cost Poor field database Hydrogen cost Refueling Standards and codes TechnologiesProsandCons

  14. Hybrid Systems

  15. Hybrid System PV - Wind - Diesel - São Tomé - Brazil

  16. Average Prices (U$/Kw) • Fuel cell – U$ 3,000/Kw • Solar Photovoltaic – U$ 400 – 1,000/Kw • Wind Energy – U$ 0,11 – 0,22 /Kwh * * Last prices in Brazil

  17. Conclusions • Today the people are more consciences about the environments • In Brazil the using the renewable energy in telecommunications companies is small • This type the energy is expensive, it is necessary the incentive programs *
