Energy costs continue to rise, a trend that will continue in the future, while broadband penetration is introducing new

active equipment to the network architecture. In this context, and to reflect other environmental aspects of

sustainability, it is vital that the main telecommunication actors implement effective general engineering of fixed and

mobile broadband networks and sites provisioning, managing or using those networks (i.e. operator sites, operator data

centres and customer data centres) in order to respond to critical issues of energy consumption while proposing essential

These issues are of particular importance in data centres - both of operators and customers. To guide this process, it is

essential that metrics are defined, termed Global Key Performance Indicators (KPI ) that enable energy usage to be

For the purposes of the present document, the following terms and definitions apply:

core infrastructure (core network): functional elements (that is equipment and infrastructure) that enable

customer data centre: data centre that is not directly connected to the core network

data centre: structure, or group of structures, dedicated to the centralized accommodation, interconnection and

operation of information technology and network telecommunications equipment providing data storage, processing and

transport services together with all the facilities and infrastructures for power distribution and environmental control

together with the necessary levels of resilience and security required to provide the desired service availability

energy consumption: total consumption of electrical energy by an operational infrastructure

energy management: combination of reduced energy consumption and increased task efficiency, re-use of energy and

energy re-use: transfer or conversion of energy (typically in the form of heat) produced by the operational

fixed access network: functional elements that enable wired (including optical fibre) communications to customer

Information Technology Equipment (ITE): equipment providing data storage, processing and transport services for

ITE and/or NTE load: total requirement for power by a set of information technology equipment (ITE) and/or network

mobile access network: functional elements that enable wireless communications to customer equipment

Network Telecommunications Equipment (NTE): equipment dedicated to providing direct connection to core and/or

Objective KPI: KPI assessing one of the objectives of operational energy performance which is subsequently used to

operational infrastructure: combination of information technology equipment (ITE) and/or network

telecommunications equipment (NTE) together with the power supply and environmental control systems necessary to

operator site: premises accommodating network telecommunications equipment providing direct connection to the

core and access networks and which may also accommodate information technology equipment

primary distribution equipment: equipment which is required to manage, control and convert incoming power

supplies (primary, secondary and, where appropriate, additional) in a form suitable for distribution by secondary

renewable energy: energy produced from dedicated generation systems using resources that are naturally replenished

secondary distribution equipment: equipment which is required to manage, control and distribute the power provided

by the primary distribution equipment to the short-break and unprotected sockets within the data centre and to the

NOTE 2: The power supply may be single-phase AC, three-phase AC or DC. If there is a change from 3-phase to

1-phase supply, this is generally achieved at the secondary distribution equipment that is served directly

task efficiency: measure of the work done (as a result of design and/or operational procedures) for a given amount of

Δt the maximum time variation between measurement points of the different Objective Key

T the minimum time between which the Objective KPIs can be assessed to determine relevant trend

Figure 1 shows the schematic of the operational infrastructures of broadband deployment as contained with the ESO

NOTE: Not all the terms and abbreviations of Figure 1 are included in clause 3 of the present document.

Figure 1: Schematic of core network together with fixed and mobile access infrastructures

• an operator data centre (ODC) accommodates a mixture of information technology equipment (ITE) and

• an operator site (OS) will also accommodate a mixture of ITE and NTE - where the NTE may provide

connections to connections to core, fixed access, terrestrial mobile access and satellite mobile access network

It is unlikely that either the ODC or OS of Figure 1 would allow separate assessment of energy consumption of the ITE

and the various NTE for the disparate network infrastructures. As a result, the boundaries applied to ODC and OS in

relation to the objective of Global KPIs for operational infrastructures have to be modified from that of Figure 1 to that

Similarly, the principal difference between the ODC and the OS would be the relative proportion of ITE and NTE as is

shown in Figure 3. Furthermore a customers data centre (CDC) would also contain NTE - although generally providing

a connection to the access networks. For this reason, the present document considers its Global KPIs for operators data

The Global KPIs are therefore applicable to ODCs, OS and CDCs of all types, regardless of:
