Introduction 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 operators implement effective general engineering of fixed and mobile broadband networks and sites provisioning, managing or using those networks (i.e. ICT sites) in order to respond to critical issues of energy consumption while proposing essential solutions to broadband deployment. To guide this process, it is essential that metrics are defined, termed Global Key Performance Indicators (KPIs), that enable energy usage to be managed more effectively. The Global Key Performance Indicators specified in the standards in the ETSI EN 305 200 series [i.2] address operational infrastructures and do not consider design or operation of individual components comprising those infrastructures. The ETSI EN 305 200 [i.2] multi-part deliverable comprises: • The present document: a generic requirements document addressing Global KPIs for operational infrastructures. • A sub-series ETSI EN 305 200-2 that defines the Global KPIs, and drives energy management targets, for specific operational networks and sites and which describes how the Global KPIs are to be applied (which may be used to support future regulatory objectives): - ETSI EN 305 200-2-1 [i.3]: "ICT sites"; - ETSI EN 305 200-2-2 [i.4]: "Fixed broadband access networks"; NOTE: Excluding cable access networks. - ETSI EN 305 200-2-3 [i.5]: "Mobile broadband access networks". The standards do not define weightings of Objective KPIs or targets or limits for Global KPIs but may contain information on values that have been used by certain organizations. • A sub-series ETSI EN 305 200-3 including ETSI EN 305 200-3-1 [i.6] that defines particular implementations of Global KPIs within ICT sites based on the requirements of ETSI EN 305 200-2-1 [i.3], and which may define levels of performance to simplify and provide clearer understanding of Global KPIs allowing the evaluation of performance of energy use management in ICT sites. The standards do not define weightings of Objective KPIs or targets or limits for Global KPIs but may contain information on values that have been used by certain organizations. • A sub-series ETSI EN 305 200-4 including ETSI EN 305 200-4-4 [i.7] that defines design assessments of Global KPIs, and drives energy management targets, for specific operational networks and sites and which describes how the Global KPIs are to be applied (which may be used to support future regulatory objectives). These standards may be considered to be a contribution to the application of ISO 50001 [i.8] in relation to the development of policy for the continuous improvement of energy management and will accelerate: • the availability of operational infrastructure architectures and network implementations that use energy more efficiently; • the definition and attainment objectives for other environmental aspects of sustainability for operational broadband networks.

NTE Network Telecommunications Equipment 4 Context for Key Performance Indicators (KPI) 4.1 Energy management and sustainability concepts ISO Guide 82 [i.9], entitled "Guide for addressing sustainability in standards", defines sustainability as "state of the global system, which includes environmental, social and economic subsystems, in which the needs of the present are met without compromising the ability of future generations to meet their own needs". The standards in the ETSI EN 305 200 series [i.2] do not specifically address any social and economic aspects of sustainability but do focus on the environmental issues in relation to the operational performance of infrastructures of deployed broadband. The standards in the ETSI EN 305 200 series [i.2] adopt the position that the environmental viability aspects of sustainability addressing those elements that relate directly to energy consumption and its outcomes within the locale of the broadband deployment infrastructures are within scope. Other aspects such as environmental elements relating to the wider impact of power generation (e.g. greenhouse gas, carbon), consumption of other resources (e.g. water), and issues such as life cycle assessment are out of scope. While it is self-evident that if less energy is consumed by an operational infrastructure then the environmental impact of that infrastructure will be reduced, it is equally important to consider: • the task effectiveness of the operation for which that energy is consumed; • while not wishing to encourage poor task effectiveness, some benefit can be seen if waste energy, typically in the form of heat, is re-used. This may substitute for, to some degree, energy from other sources. Energy consumption, task effectiveness, re-use of waste heat and the contribution of locally generated energy from renewable sources are considered to work in concert, albeit to different degrees for different infrastructures. In the ETSI EN 305 200 series [i.2], these four aspects are considered and specified as Objective KPIs from which Global KPIs are produced (see clause 4.2) which reflect energy management of operational systems - meeting the needs of operators and legislators alike. The imperatives placed on the different elements may vary from time to time - regulators specifically encouraging local generation of energy from renewable sources but then shifting focus on to other areas. 4.2 Differentiation of Key Performance Indicators 4.2.1 General It is common for equipment suppliers to define the energy efficiency of their products in terms of either: • the energy consumed to perform specific tasks; or • task performance improvements for a given energy consumption. Within the ETSI EN 305 200 series [i.2], these are considered, separately, as improvements in "energy consumption" and "task effectiveness" respectively. SIST EN 305 200-1 V1.1.1:2018
ETSI ETSI EN 305 200-1 V1.1.1 (2018-07) 11By comparison, operators and legislators are more interested in the performance of complete systems at an operational level taking into account global management aspects. As a result they apply a wider view of energy management that combines energy consumption and task effectiveness with more general objectives. Against this background, the standards in the ETSI EN 305 200 series [i.2] recognize and differentiate between three types of energy-related KPIs as shown schematically in Figure 1. Operational Global and Objective KPIs are fundamentally different to the Technical KPIs applied to products and systems at the design and engineering stages. The former are used to monitor and drive user behaviour whereas the latter are substantial indications of potential operational performance. It is therefore important to support, but differentiate, the role of the Technical KPIs from the Objective and Global operational KPIs.
Figure 1: The relationship of energy related Technical, Objective and Global KPIs Technical KPIs relate to the design and engineering phase for the components, sub-assemblies, products and systems to be employed in the infrastructures of broadband deployment. They are measured under specific operating conditions and provide indications of potential performance in an operational infrastructure. These are not addressed by the ETSI EN 305 200 series [i.2]. The left-hand side of Figure 1 relates to the Technical KPIs of the design and engineering phase for components, sub-assemblies, products and

Introduction
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 operators implement effective general engineering of fixed
and mobile broadband networks and sites provisioning, managing or using those networks (i.e. ICT sites) in order to
respond to critical issues of energy consumption while proposing essential solutions to broadband deployment. To guide
this process, it is essential that metrics are defined, termed Global Key Performance Indicators (KPIs), that enable
energy usage to be managed more effectively.
The Global Key Performance Indicators specified in the standards in the ETSI EN 305 200 series [i.2] address
operational infrastructures and do not consider design or operation of individual components comprising those
infrastructures.
The ETSI EN 305 200 [i.2] multi-part deliverable comprises:
• The present document: a generic requirements document addressing Global KPIs for operational
infrastructures.
• A sub-series ETSI EN 305 200-2 that defines the Global KPIs, and drives energy management targets, for
specific operational networks and sites and which describes how the Global KPIs are to be applied (which may
be used to support future regulatory objectives):
- ETSI EN 305 200-2-1 [i.3]: "ICT sites";
- ETSI EN 305 200-2-2 [i.4]: "Fixed broadband access networks";
NOTE: Excluding cable access networks.
- ETSI EN 305 200-2-3 [i.5]: "Mobile broadband access networks".
The standards do not define weightings of Objective KPIs or targets or limits for Global KPIs but may contain
information on values that have been used by certain organizations.
• A sub-series ETSI EN 305 200-3 including ETSI EN 305 200-3-1 [i.6] that defines particular implementations
of Global KPIs within ICT sites based on the requirements of ETSI EN 305 200-2-1 [i.3], and which may
define levels of performance to simplify and provide clearer understanding of Global KPIs allowing the
evaluation of performance of energy use management in ICT sites.
The standards do not define weightings of Objective KPIs or targets or limits for Global KPIs but may contain
information on values that have been used by certain organizations.
• A sub-series ETSI EN 305 200-4 including ETSI EN 305 200-4-4 [i.7] that defines design assessments of
Global KPIs, and drives energy management targets, for specific operational networks and sites and which
describes how the Global KPIs are to be applied (which may be used to support future regulatory objectives).
These standards may be considered to be a contribution to the application of ISO 50001 [i.8] in relation to the
development of policy for the continuous improvement of energy management and will accelerate:
• the availability of operational infrastructure architectures and network implementations that use energy more
efficiently;
• the definition and attainment objectives for other environmental aspects of sustainability for operational
broadband networks.

4 Context for Key Performance Indicators (KPI)
4.1 Energy management and sustainability concepts
ISO Guide 82 [i.9], entitled "Guide for addressing sustainability in standards", defines sustainability as "state of the
global system, which includes environmental, social and economic subsystems, in which the needs of the present are
met without compromising the ability of future generations to meet their own needs".
The standards in the ETSI EN 305 200 series [i.2] do not specifically address any social and economic aspects of
sustainability but do focus on the environmental issues in relation to the operational performance of infrastructures of
deployed broadband.
The standards in the ETSI EN 305 200 series [i.2] adopt the position that the environmental viability aspects of
sustainability addressing those elements that relate directly to energy consumption and its outcomes within the locale of
the broadband deployment infrastructures are within scope.
Other aspects such as environmental elements relating to the wider impact of power generation (e.g. greenhouse gas,
carbon), consumption of other resources (e.g. water), and issues such as life cycle assessment are out of scope.
While it is self-evident that if less energy is consumed by an operational infrastructure then the environmental impact of
that infrastructure will be reduced, it is equally important to consider:
• the task effectiveness of the operation for which that energy is consumed;
• while not wishing to encourage poor task effectiveness, some benefit can be seen if waste energy, typically in
the form of heat, is re-used. This may substitute for, to some degree, energy from other sources.
Energy consumption, task effectiveness, re-use of waste heat and the contribution of locally generated energy from
renewable sources are considered to work in concert, albeit to different degrees for different infrastructures. In the ETSI
EN 305 200 series [i.2], these four aspects are considered and specified as Objective KPIs from which Global KPIs are
produced (see clause 4.2) which reflect energy management of operational systems - meeting the needs of operators and
legislators alike.
The imperatives placed on the different elements may vary from time to time - regulators specifically encouraging local
generation of energy from renewable sources but then shifting focus on to other areas.
4.2 Differentiation of Key Performance Indicators
4.2.1 General
It is common for equipment suppliers to define the energy efficiency of their products in terms of either:
• the energy consumed to perform specific tasks; or
• task performance improvements for a given energy consumption.
Within the ETSI EN 305 200 series [i.2], these are considered, separately, as improvements in "energy consumption"
and "task effectiveness" respectively.
ETSI
---------------------- Page: 10 ----------------------
11 ETSI EN 305 200-1 V1.1.1 (2018-07)
By comparison, operators and legislators are more interested in the performance of complete systems at an operational
level taking into account global management aspects. As a result they apply a wider view of energy management that
combines energy consumption and task effectiveness with more general objectives.
Against this background, the standards in the ETSI EN 305 200 series [i.2] recognize and differentiate between three
types of energy-related KPIs as shown schematically in Figure 1. Operational Global and Objective KPIs are
fundamentally different to the Technical KPIs applied to products and systems at the design and engineering stages. The
former are used to monitor and drive user behaviour whereas the latter are substantial indications of potential
operational performance.
It is therefore important to support, but differentiate, the role of the Technical KPIs from the Objective and Global
operational KPIs.

4.1 Energy management and sustainability concepts
ISO Guide 82 [i.9], entitled "Guide for addressing sustainability in standards", defines sustainability as "state of the
global system, which includes environmental, social and economic subsystems, in which the needs of the present are
met without compromising the ability of future generations to meet their own needs".
The standards in the ETSI EN 305 200 series [i.2] do not specifically address any social and economic aspects of
sustainability but do focus on the environmental issues in relation to the operational performance of infrastructures of
deployed broadband.
The standards in the ETSI EN 305 200 series [i.2] adopt the position that the environmental viability aspects of
sustainability addressing those elements that relate directly to energy consumption and its outcomes within the locale of
the broadband deployment infrastructures are within scope.
Other aspects such as environmental elements relating to the wider impact of power generation (e.g. greenhouse gas,
carbon), consumption of other resources (e.g. water), and issues such as life cycle assessment are out of scope.
While it is self-evident that if less energy is consumed by an operational infrastructure then the environmental impact of
that infrastructure will be reduced, it is equally important to consider:
• the task effectiveness of the operation for which that energy is consumed;
• while not wishing to encourage poor task effectiveness, some benefit can be seen if waste energy, typically in
the form of heat, is re-used. This may substitute for, to some degree, energy from other sources.
Energy consumption, task effectiveness, re-use of waste heat and the contribution of locally generated energy from
renewable sources are considered to work in concert, albeit to different degrees for different infrastructures. In the ETSI
EN 305 200 series [i.2], these four aspects are considered and specified as Objective KPIs from which Global KPIs are
produced (see clause 4.2) which reflect energy management of operational systems - meeting the needs of operators and
legislators alike.
The imperatives placed on the different elements may vary from time to time - regulators specifically encouraging local
generation of energy from renewable sources but then shifting focus on to other areas.
4.2 Differentiation of Key Performance Indicators
4.2.1 General
It is common for equipment suppliers to define the energy efficiency of their products in terms of either:
• the energy consumed to perform specific tasks; or
• task performance improvements for a given energy consumption.
Within the ETSI EN 305 200 series [i.2], these are considered, separately, as improvements in "energy consumption"
and "task effectiveness" respectively.

11 Draft ETSI EN 305 200-1 V1.1.0 (2018-04)
By comparison, operators and legislators are more interested in the performance of complete systems at an operational
level taking into account global management aspects. As a result they apply a wider view of energy management that
combines energy consumption and task effectiveness with more general objectives.
Against this background, the standards in the ETSI EN 305 200 series [i.2] recognize and differentiate between three
types of energy-related KPIs as shown schematically in Figure 1. Operational Global and Objective KPIs are
fundamentally different to the Technical KPIs applied to products and systems at the design and engineering stages. The
former are used to monitor and drive user behaviour whereas the latter are substantial indications of potential
operational performance.
It is therefore important to support, but differentiate, the role of the Technical KPIs from the Objective and Global
operational KPIs.
