Telecommunications & Energy: where are we going ?

During the last years TLC have deeply changed…..

…… and even more will change in the near future

Wireline network domain

E TOT

E TLC

E TOT: total energy consumption from mains (TLC equipment, cooling, ausiliary systems)

E TLC: energy consumption of TLC equipment


Past energy trends l.jpg
Past energy trends

In the ‘80 and ‘90 the network migrated towards full digital switching and transmission

This change had a strong impact on network’s energy consumption …

… was it possible to perform better?

High BB penetration in the last few years…

  • …with a related growth of the TLC energy demand

  • …but the new strong attention towards energy consumption has allowed a reduction of the total demand, mainly through:

    • cooling optimization

    • increased efficiency on Energy Systems

Today, the energy needed by the Telecom Italia’s Network is

more than 2.000.000.000.000 Wh (>2 TWh)

representing nearly 1% of the total National energy demand, second national user


Efficiency actions i l.jpg
Efficiency Actions (I)

  • Energy efficiency and dismissal of obsolete platform

    • Dismissal of obsolete trasmission and data platform

    • Rationalization of PSTN exchanges

    • Introduction of Free Cooling in the C.O.

    • Replacement and rationalisation of conditioning plants

    • Rise of the maximum temperature acceptable within an equipment room

  • Process efficiency: rationalization and simplification

  • Network Infrastructure and platform efficiency

    • Further fixed-mobile integration/simplification/modernization

    • OSS integration

  • Central Office disposal/clustering in a single location

  • Working space optimization

  • Organization evolution/rationalization


Efficiency actions ii l.jpg
Efficiency Actions (II)

Eco-Efficiency Indicator

  • The growing need of performance monitoring in the Sustainability area has led to the creation of an Eco-Efficiency Indicator

  • The Indicator is calculated as the ratio of the total traffic processed by the network (bit) and the global TI energy consumption (kWh, Joule)

  • Since 2006, the Indicator has been inserted in the Telecom Italia Sustainability Report(1)

Eco Efficiecy Indicator

Forecast 2007 set in the end of 2006: growth of 40%, with a total value of ~850 Bit/Joule

Efficiency actions iii l.jpg
Efficiency Actions (III)

CoC (Code of Conduct)

  • Power consumption reduction is a priority for the European Commission, especially for those sectors with a high development rate (e.g. BroadBand)

  • The norm is lacking, so EU has promoted a set of Code of Conduct [CoC] in order to minimize consumpion by BB, Data Center, STB, CPE equipment

  • CoC has been developed by heterogenous Working Groups: Authorities, Operators, Vendors

  • Telecom Italia is an active participant to the CoCs drafting

  • The objectives have to be pursued both at Standardization level and through “ad hoc” Purchasing policies

    New targets for CoC BB (last update on July ‘07) (1):

(1) Values are related to fully equipped DSLAMs with more than 100 lines


Efficiency actions iv l.jpg
Efficiency Actions (IV)

2006-2008 Environmental targets for Telecom Italia

  • Energy

    Optimize energy consumption

  • Waste

    Improve waste recycling management

  • Paper

    Reduce paper consumption and promote the use of recycled paper

  • Emissions

    Reduce emissions produced by vehicles and by heating system

  • Electromagnetism

    • Promote SAR (Specific Absorbtion Rate) qualification of handsets

    • Optimize electromagnetic fields management of the Base Transceiver Stations

Future trends iii l.jpg
Future trends (III)

Telecom Italia NGN2 (3/3)

  • Evolutionary services require the introduction of optical fiber in the access to shorten the copper drop…

  • … therefore, a new network paradigm of discontinuity is expected:

    • from many Central Offices with medium/high electrical load…

    • … to a limited number of very high load sites (e.g. Data Centers) and many distributed deployments in the access network due to the new topology of NGN2

  • The architectural solution (eg. Overlay vs Total Replacement) will have a strong impact on total energy consumption

A VDSL2 chip can transmit about 5 times more bits/s than ADSL2+, but requires at least double the energy to operate……

…….and even higher speeds/complexities are on the way


Future trends iv l.jpg
Future trends (IV)

Energy consumption and cost

  • Energy as a key issue for the NGN2 deployment

    • Energy consumption has a strong impact on

      • feasibiliy

      • sustainability/corporate image (Kyoto)

    • The electrical energy unit cost is expected to grow over the next years

Unit cost

> +200%

Exploring or re exploring possibilities for energy in telecommunications l.jpg
Exploring (or re-exploring) possibilities for energy in Telecommunications

  • Wireless Energy Transmission: “Wikitricity”

    • TILab prototyping running for wireless power transfer (MIT also working on this issue)

    • Next steps: use for the powering of ZigBee nodes (WSN) and for trials like ecoupled.

    • Total Energy Cost: distribution more expensive than consumption

  • Architectural efficiency: “Maxwell’s devil”

    • Localized cooling of “hot spots” for critical network equipment through Vortex technology (compressed air in input “splitted” in two separated hot and cold air flows

    • Relative low yields

    • Optimization at System Level

Solutions have to be found at an architectural system wide level !


User side power consumption l.jpg
User side power consumption Telecommunications

  • Lots of BroadBand related appliances/gadgets already populate our homes…

    …and many more will come

  • Their consumption is already comparable to that ofthe Telecom Network part

Energy optimization actions are in progress (CoC, Energy Star …) and more will have to be developed to avoid an uncontrollable increase in the home

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


Conclusions i l.jpg
Conclusions (I) Telecommunications

  • TLC Operators have to be efficient and flexible to face the new market challenges, even more than in the past

    • Further optimization and efficiency in HVAC (Heating, Ventilation Air Conditioning) and Energy System domain

    • Innovative/alternative solutions for energy supply

    • Choice of the most suitable architectural solutions (e.g. total replacement)

    • TCO for new systems/equipments including OPEX for energy consumption during the calls for bids (TI Purchasing Department has just adopted this strategy)

    • Optimization and efficiency at Equipment level (“intrinsic efficiency”)

      • push towards system/chipset vendors (strong attention to the power consumption since the early design phase)

      • further actions towards standardization bodies (ETSI, ITU-T) are required

      • actions also at (inter)national Government level (rif EU CoCs, ETNO)

      • Eco-Efficiency Indicators


Conclusions ii l.jpg
Conclusions (II) Telecommunications

  • New investments on technological R&D for NGN2’s innovative energy systems (invest today to save tomorrow)

  • Commitment towards Energy Saving, with special attention to Environment and Sustainability issues (e.g. global warming, Kyoto protocol,…), has for sure a positive impact in terms of Social Responsibility and Corporate image, and it can also lead to a greater competitiveness in the market arena

    A strategy oriented towards Energy Efficiency yields benefits for the Company and for the whole Community
