GWh E TOT: total energy consumption from mains (TLC equipment, cooling, auxiliary systems) E TLC: energy consumption of TLC equipment End of network digitalization Energy consumption became a Key Issue Wireline network domain Start of network digitalization Start ADSL deployment New challenge on energy saving Need of further actions on TLC equipments E TOT E TLC Appliances Power Consumpt.

6 OPEX for Energy in Telecom Italia - 1 Energy represents the most significant cost Strong attention to this issue since the 90ies actions have been taken to tackle it Projct Ambient & Efficiency Plan Network t k Energy Consumption significantly ifi decreased in the last 5 years, in spite of the growth in the number of equipment and services (BB) 5

7 OPEX for Energy in Telecom Italia - 2 In spite of total consumption decrease cost has increased From 5 cent/kwh in 2000 to 13,5 cent/kwh in 2007 world crises has lowered energy cost. but we hope it will increase again!!!! It will happen soon 6

9 OPEX for Energy in Telecom It - 3 All Company areas are accountable Consumption reduction requires team effort. NGN2: Crucial the consumption of the new equipment OPEX for energy are an integral part of bids evalutation ti TCO 5-10 years Architectural choices have a strong impact on consumption (hundreds of GWh) 8

10 CAPEX, OPEX and environmental impact of the solutions Capex /user Opex O&M Environmental impact /user /user % of penetration FTTCab FTTB FTTH (GPON) W/user Power consumption Year Power consumption Recycling costs Noise Size on field The best balance among these aspects has to be selected 9

11 The Energy consumption distribution in Telecom Italia - today ICT Mobile Network Offices Telecom Italia total domestic consumption: ~2,1TWh (year 2006) OLO/LLU Cooling Fixed Network NB Switching BB and remote equipment will grow NB switching is going to decrease and will induce a reduction in cooling Moreover, cooling is obviously related to the energy saving of BB BB and remote equipm. Transport Fixed network is the main part 10

12 GRUPPO TELECOM ITALIA The Energy consumption distribution in Telecom Italia - tomorrow 11

13 New approaches on Cooling 12

14 New approaches on Cooling (and beyond): Kaleidos TODAY IN CENTRAL OFFICES Joint Research Program with Berkeley WSN Trials in Telecom Central Offices Results: Consumption decrease from 6,4MWh to 4,3MWh (3000 per CO, 100 per point) batteries life 3 years flexible, expandable and reconfigurable sticker installation no wiring required TOMORROW IN THE HOMES 13

15 EU actions towards the 20 / 20 / 20 Code of Conducts Problem! In EU: ICT (BroadBand, Data Center, External Power Supply, UPS and Digital TV) could grow up to 250TWh by 2015 (the same amount used today by the whole Spain) A solution! EU developed 5 Codes of Conduct on these areas ec europa eu/energyefficiency/html/standby initiative htm The goal is to set ambitious targets and best practices, involving vendors and Operators towards an anticipated development and an earlier availability of efficient equipment CoCs are (currently) based on voluntary subscription Failing these goals would further empower mandatory actions (e.g. EuP) 14

16 Energy Efficiency GTTI Parma EU actions Code of Conducts The BB CoC is already the reference for Industries and Operators It paves the way for much greater EE at the Client and the Operator 15

17 Beyond CoCs CoCs draw the base line, but we expect (much) better equipment TCO is used in tender evaluation and it gives strong advantage to the least energy hungry equipment (in equipment such as ADSL2+, the energy OPEX equals the initial CAPEX in just 5 years) CoCs aim at the efficiency from the single equipment point of view We need to do more! Enable the enormous efficiency potentials of standby trough all the service chain New specifications should define how, ports with no activity, should enter a low power state without disrupting the higher layers (e.g. how to a VoIP terminal can go to standby without losing its IP address, authentication ) need to act at ITU-T, IEEE, ETSI, IETF, BBF, HGI level Enable the use of DSL low power modes CPE must dinamically activate low power mode for sub functions not in use Radio Base Stations must switch off their second channel when traffic is low... 16

18 User side power consumption Lots of BroadBand related appliances/gadgets already populate our homes and many more will come Their consumption is already comparable to that of the Telecom Network part W/average user - Today User side Network side 4x W/average user Long term Network side User side Cons: Customers have to be made aware on the energy behavior of the systems they are buying as it can have serious effects on their energy bill Pros: ICT and Smart grids can can enable great savings for end users 17

19 Wanna save money soon?.. Go standard! Rethink standards! No real competition among Operators on EE! Vendors need to guarantee longer life to their products Products are global! Costly to develop, especially for every single market! Working together on Standardization is a win-win but there is the need for Coordinated d action among Operators, Vendors, Academia and Std. Bodies Strong commitment of Regulators/Governments 18

20 The Energy Efficiency Inter-Operator Collaboration Group (EEIOCG) Defines high level strategic actions and coordinated guidance towards Standardization Equipment suppliers (both network and user side) in order to speed up the availability l of Energy Efficient equipment and networks, helping vendors towards investments optimization 19

21 Energy Efficiency and ICT FACTS: Utilization is low Edge devices are mostly idle Speed costs energy Reducing latency costs IP will go everywhere Most of the ICT energy consumption will be at the edge (User) will be at the edge (User) Economics matter POSSIBILITIES: Think broadly Re-think your objectives Design for real operating conditions, not for peak Integrate networks and appliances Use Network to get info and enable edge devices savings Source: B.
