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 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
solutions to true broadband deployment. To guide this process, it is essential that metrics are defined, termed Global
Key Performance Indicators (KPI ) that enable energy usage to be managed more effectively.
EM
The ES 205 200 series of standards comprises:
• ES 205 200-1: a generic requirements document addressing Global KPIs for operational infrastructures;
NOTE: Global KPIs do not address design/operation of components or subsystems of broadband deployment
networks.
• a sub-series ES 205 200-2 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);
- ES 205 200-2-1: Data centres;
- ES 205 200-2-3: Mobile access networks.
These documents do not define KPI limits or targets (which is outside the scope of the ES 205 200 series of
standards).
These documents will accelerate:
• 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.
Within the present document:
• clause 4 explains the context underlying the need for the development of Global KPIs for energy efficiency
and introduces the Objective KPIs upon which the Global KPIs are founded;
• clause 5 outlines the role of the Objective KPIs that are used throughout the ES 205 200-2 series;
• clause 6 describes the general requirements that are applied to all KPIs defined within the ES 205 200-2 series;
• clause 7 provides a mapping of the operational infrastructures addressed by the ES 205 200-2 series to those
described in the ESO response to the European Commission Mandate M/462 [i.1];
• clause 8 summarizes the applicability of the Global and Objective KPIs defined in the ES 205 200-2 series;
• Annex A discusses the roles of different types of Key Performance Indicators i.e. Technical, Objective and
Global in relation to the overall energy management concepts of the present document.

The Global Key Performance Indicators (KPI) for energy management (KPI ) specified in the ES 205 200 series of
EM
standards shall reflect and encourage:
Objective 1: a reduction in energy consumption;
NOTE: Other sustainability issues are not considered within ES 205 200-1 or ES 205 200-2.
Objective 2: improvements in task efficiency (although the meaning of task efficiency may depend on the
particular operational infrastructure);
Objective 3: the re-use of energy;
Objective 4: the contribution of renewable energy.
While objectives 1 and 2 are in the foreground of the development of all Global KPIs, the relative priority given to the
objectives 3 and 4 above may differ depending on the opportunities available to the particular operational infrastructure.
Figure 1 shows the combination and inter-relation of the four objective KPIs in the production of the KPI for an

Key Performance Indicators (KPI ) that enable energy usage to be managed more effectively.
EM
The ES 205 200 series of standards comprises:
• ES 205 200-1: a generic requirements document addressing Global KPIs for operational infrastructures;
NOTE: Global KPIs do not address design/operation of components or subsystems of broadband deployment
networks.
• a sub-series ES 205 200-2 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);
- ES 205 200-2-1: Data centres;
- ES 205 200-2-3: Mobile access networks.
These documents do not define KPI limits or targets (which is outside the scope of the ES 205 200 series of
standards).
These documents will accelerate:
• 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.
Within the present document:
• clause 4 explains the context underlying the need for the development of Global KPIs for energy efficiency
and introduces the Objective KPIs upon which the Global KPIs are founded;
• clause 5 outlines the role of the Objective KPIs that are used throughout the ES 205 200-2 series;

4 Context
The Global Key Performance Indicators (KPI) for energy management (KPI ) specified in the ES 205 200 series of
EM
standards shall reflect and encourage:
Objective 1: a reduction in energy consumption;
NOTE: Other sustainability issues are not considered within ES 205 200-1 or ES 205 200-2.
Objective 2: improvements in task efficiency (although the meaning of task efficiency may depend on the
particular operational infrastructure);
Objective 3: the re-use of energy;
Objective 4: the contribution of renewable energy.
While objectives 1 and 2 are in the foreground of the development of all Global KPIs, the relative priority given to the
objectives 3 and 4 above may differ depending on the opportunities available to the particular operational infrastructure.
Figure 1 shows the combination and inter-relation of the four objective KPIs in the production of the KPI for an
EE
operational infrastructure.
